Foster, Bryan. "Green Forestry? Case Studies of Sustainable Forestry and Forest Certification." ScholarWorks @ UVM, 2008. http://scholarworks.uvm.edu/graddis/84.
Full textAbstract:
Abstract This dissertation explored sustainable forest management from multiple perspectives: a literature-based investigation to define management practices that sustain ecological, economic, and social forest resources over time; a field-based research project to identify management practice differences between Forest Stewardship Council (FSC) certified, Sustainable Forestry Initiative (SFI) certified, and uncertified properties in Maine; and a field-based research project to identify stand structural differences between FSC certified and uncertified properties in Vermont. Based on an extensive literature review, we developed an iterative decision-making framework of goal-setting/implementation/ monitoring/review that could assist forest owners in choosing management practices to sustain ecological, economic, and/or social capital over multiple time frames. Our unique contribution is the identification of six concrete management concepts at the implementation phase: (1) BMPs/RIL, (2) biodiversity conservation, (3) community forestry, (4) forest protection, (5) sustained forest product yield, and (6) triad forestry. Forest owners can implement practices under one or more of these concepts to achieve their sustainability goals. We illustrate a hypothetical application of our framework with a case study of an FSC certified managed natural forest in the lowland tropical region of Costa Rica. In the white pine forests of south-central Maine, we compared three FSC, SFI, and uncertified private properties against local scale Montreal criteria using triangulation of evidence from management documents, staff interviews, and field inspections. Certified properties were associated with improved internal management systems and improved practices for biodiversity conservation. However, our data suggest that certification does not necessarily involve fulfillment of all Montreal criteria, such as adherence to sustained timber yield, consideration of multiple social issues, or ecological monitoring at multiple temporal and spatial scales. In northern hardwood stands in central Vermont, we compared three FSC certified and three uncertified that were analogous in terms harvesting date, silvicultural treatment type, forest type, and general location. The uncertified sites were randomly selected to remove bias. We conducted stand structural analysis of both live trees and standing and downed coarse woody debris, and also developed 10-year growth projections using FVS/NE-TWIGS. Our data suggest that FSC certified stands had similar timber economic value, similar live tree structure, and similar tree carbon storage, but significantly greater residual coarse woody debris than comparable uncertified harvested stands.

Full textAbstract:
Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. The working machines for CTL logging are heavy and their suspension systemis generally rudimentary, basically the only damping is provided by the tires. To meet futuredemands on operator comfort, sustainable forestry, and climate concerns, significant challenges areto find means for reducing daily vibration dosage, soil damage, and rolling resistance.Paper A proposes a full-scale virtual model of a four-wheeled forwarder concept equipped with twopendulum axels with an actively controlled hydraulic suspension system mounted on each wheelaxle. The simulation results are then analyzed to determine the required actuation power.Paper B presents a performance comparison of a six-wheeled medium-sized pendulum-armsuspended forwarder, with three different suspension systems; active, semi-active, and passive. Amethodology to optimize and analyze forestry vehicle suspension performance based on multi-bodydynamic simulations are proposed and applied for the studied forwarder.Paper C is a model-based investigation of the dynamic behavior of a traditional eight-wheeledbogie type of forwarder with the main focus on identifying critical issues and suggesting criteria forassessing the performance of the machine while traveling on sloped and rough terrain.Paper D investigates the performance of a novel all-wheel-drive pendulum-arm suspendedmedium-sized forestry machine with passive and active chassis suspensions. The dynamicperformance of the pendulum-arm machine concept is quantified with simulations and comparedwith a “traditional” bogie-machine.Paper E investigates how to model a tracked forwarder and how the performance comparison canbe evaluated in multi-body simulation software like Adams ATV.Paper F presents a comparison of the dynamic behavior of forestry machines with different types ofpassive chassis suspensions from three perspectives: their gentleness to terrain, operator and theirpotential for improved fuel efficiency.Paper G proposes a 12 degrees-of-freedom multi-body dynamics simulation model of a standardeight-wheeled bogie type of medium-sized forwarder and verifies the simulation model withmeasured data from the field test that was carried out the actual machine.Paper H reconfigures the model presented in Paper G and compares a medium-sized forwarderequipped with two different track units with the performance of a wheeled and bogie-type offorwarder on hard rough ground, as well as on soft soil.QC 20170123

Zurba, Kamal. "Is short rotation forestry biomass sustainable?" Doctoral thesis, Technische Universitaet Bergakademie Freiberg Universitaetsbibliothek "Georgius Agricola", 2016. http://nbn-resolving.de/urn:nbn:de:bsz:105-qucosa-212162.
Full textAbstract:
Despite the negative effects of fossil fuels on the environment, these remain as the primary contributors to the energy sector. In order to mitigate global warming risks, many countries aim at reducing greenhouse gas emissions. Bioenergy crops are being used as a substitute for fossil fuels and short rotation forestry is a prime example.
In order to examine the sustainability of energy crops for fuel, typical European short rotation forestry (SRF) biomass, willow (Salix spp.) and poplar (Populus spp.) are examined and compared to rapeseed (Brassica napus L.) in respect to various aspects of soil respiration and combustion heat obtained from the extracted products per hectare.
Various approaches are used to look at an As-contaminated site not only in the field but also in a soil-column experiment that examines the fate of trace elements in SRF soils, and in an analysis using MICMAC to describe the driving factors for SRF crop production. Based on the cause-effect chain, the impacts of land-use change and occupation on ecosystem quality are assessed when land-use is changed from degraded land (grassland) to willow and poplar SRF.
A manual opaque dynamic closed chamber system (SEMACH-FG) was utilized to measure CO2 emissions at a willow/poplar short rotation forest in Krummenhennersdorf, Germany during the years 2013 and 2014, and at a rapeseed site in 2014.
Short rotation forest soils showed higher CO2 emission rates during the growing season than the dormant season – with a CO2 release of 5.62±1.81 m-2 s-1 for willows and 5.08±1.37 µmol CO2 m-2 s-1 for poplars in the growing season. However, during the dormant season the soil sites with willow emitted 2.54±0.81 µmol CO2 m-2 s-1 and with poplar 2.07±0.56 µmol CO2 m-2 s-1. The highest emission rates for the studied plantations were observed in July for both years 2013 and 2014, during which the highest air and soil temperatures were recorded.
Correlations between soil emission of CO2 and some meteorological parameters and leaf characteristics were investigated for the years 2013 and 2014. For example, for the willow clone (Jorr) and poplar clone (Max 3), high correlations were found for each between their soil emission of CO2 and both soil temperature and moisture content. Fitted models can explain about 77 and 75% of the results for Jorr and Max 3 clones, respectively. Moreover, a model of leaf area (LA) can explain about 68.6% of soil CO2 emission for H275. Estimated models can be used as a gap-filling method, when field data is not available.
The ratio between soil respiration and the combustion heat calculated from the extracted products per hectare was evaluated and compared for the study’s willow, poplar and rapeseed crops. The results show that poplar and willow SRF has a very low ratio of 183 kg CO2 GJ 1 compared to rapeseed, 738 kg CO2 GJ 1.
The soil-column experiment showed that by continuing the SRF plantation at the As-contaminated site, remediation would need only about 3% of the time needed if the site was left as a fallow field.
In order to understand the complex willow and poplar short rotation forestry production system, 50 key variables were identified and prioritized to describe the system as a step to enhance the success of such potentially sustainable projects. The MICMAC approach was used in order to find the direct and the indirect relationships between those parameters and to classify them into different clusters depending on their driving force and interdependency. From this, it can be summarized that in order to enhance the success of a SRF system, decision makers should be focussing on: ensuring a developed wood-fuel market, increasing farmers’ experience/training, improving subsidy regulations and recommending a proper harvesting year cycle.
Finally, the impacts of land-use change and occupation on the ecosystem quality were assessed. Results show that establishing SRF plantations on degraded lands improved the ecosystem structural quality (ESQ) by about 43% and ecosystem functional quality (EFQ) by about 12%.
Based on overall results, poplar and willow SRF biomass can be recommended as renewable and sustainable sources for bioenergy.

Full textAbstract:
Currently the vast majority of Crown forestland in BC is managed by large private forest
corporations who hold industrial tenures. Concerns over the long term ecological and
social implications of forest management have generated increased support for small
scale forestry such as woodlot licences: Woodlots are the smallest tenure available in
the province, typically held by individuals, families, small corporations, and First Nations.
While many practitioners, academics, and environmentalists assert that small landholder
forest operations offer a comprehensive approach to forest management, there is a gap
between the supposed benefits of small scale forestry and empirical conclusive
evidence. The aim of this thesis is to fill this gap. Efforts made by woodlot licence
holders to implement sustainable forest management are examined. In addition
challenges experienced by licencees in their attempts at sustainable forestry initiatives
are analyzed. All woodlot licence holders in the province were surveyed via a mail out
questionnaire. 211 of the 813 licencees answered the survey. The according response
rate of 25.9 % is considered acceptable to make inferences about woodlots across the
province. Results indicate that the average woodlot operator undertakes a number of
voluntary measures that often surpass provincial requirements intended to institute more
ecologically sound and socially responsible forestry. The indicators of sustainable forest
management woodlot operators fall short of meeting are recognizing and consulting
First Nations regarding their rights to traditional lands and resources, and managing and
marketing diverse forest products. Licence holders identified administrative and
operating costs imposed by current provincial regulations, as the most significant barrier
undermining voluntary sustainable forestry practices. A number of recommendations to
address identified barriers were proposed by licencees. The most common proposal
was the provincial adoption of cost saving incentive driven administrative requirements
that reward operators applying sustainable measures of forest stewardship. The
findings of this research suggest that if appropriate revisions are made to woodlot
regulations, the expansion of the Woodlot Licence Program will encourage more
sustainable forest management of Crown land throughout the province.Applied Science, Faculty of

Full textAbstract:
Deforestation is a serious problem in Indonesia as a result of forest concessions that were granted by the government to private companies. The forest destruction was also caused by the encroachment by villagers during the political chaos and lack of law enforcement following the collapse of the New Order regime in 1998. In Lombok, villagers entered forests around their village, logged the trees and occupied the forests to plant fruit trees. As a response to this encroachment, the Indonesian government encouraged local participation by involving communities in forest management, which eventually developed into a community forestry management scheme. However, improper management by the forest farmers has generated negative externalities, primarily a reduction in the quantity and quality of water supply produced from the forest. To address the negative externalities problem, the local government in West Lombok developed a system of Payment for Ecosystem Services (PES). Importantly, the PES program in West Lombok was integrated with the Community Forestry program, designed for forest conservation and poverty alleviation.
This study investigates the impact of the integrated Community Forestry and PES programs on local forest conservation and socio-economic improvement. The study utilises “participatory econometrics” as a mixed quantitative and qualitative research method. The research included in-depth interviews, field visits, surveys, a focus group discussion and aerial photo analysis.
This thesis found that the PES program in West Lombok is a hybrid system that combines Coasean and Pigouvian theory. In conjunction with the Community Forestry program, the PES program could produce a sustainable outcome in the long term. This is confirmed by empirical evidence, as integrated PES and the Community Forestry program accommodates local needs, and can be used as a tool for forest conservation and the improvement of socio-economic conditions in the long term.

Buckingham, Kathleen. "The marginalisation of an orphan species : examining bamboo's fit within international forestry institutions." Thesis, University of Oxford, 2013. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.669868.
Full textAbstract:
This thesis presents an examination of the interplay between bamboo and institutions of resource management in China, India and internationally, highlighting the need for greater diversity and scope of Western dominated forestry institutions and associated mechanisms. Firstly, the thesis aims to explore the conceptual understanding of forests and the exclusion of bamboo from this construction. The key reason this question is important is that it changes the 'technological zones‘ of forestry. Growing resource scarcity has meant that bamboo is now an increasingly important input in the global forest products marketplace. Secondly, the thesis aims to examine how governance mechanisms and actors respond to the inclusion of this new input. The thesis adopts the 'paper route'; the first paper traces the socio-historical reasons why bamboo‘s potential is yet to be realised, particularly within international policy. It considers the challenges of forestry being predominantly conceptualised as treed lands and the implications for the limited efficacy of sustainable forestry, carbon and trade instruments when applied to bamboo. The second paper acts as an introduction to Western produced forest certification devices, focusing on their transformation within forestry institutions and perceived legitimacy within China. The third paper focuses on a case study of bamboo certification in India. The final paper analyses the controversy regarding the efficacy of forest certification for bamboo globally. The thesis aims to explore these topics through three lines of theory. First, it contributes to institutional framing theory by examining where the idea of a 'forest' originated from and the consequences this has had for the rise of bamboo as a 'timber' product. Second, the thesis aims to further legitimacy theory in two key ways, by examining how the Chinese government accommodates and facilitates the differing needs of both international and domestic markets, whilst ultimately assuming a legitimate form of (institutionalised) domestic governance, and how the perceived input (procedure) and output (efficacy) legitimacy influence the potential success of current and future forest certification for bamboo. Third, the thesis seeks to provide a dynamic analysis of the role of certification through the lens of performativity, which uncovers how certification can create different realities for different actors. This thesis is timely and important for a number of reasons. Firstly, China is gaining more prominence on the world stage, both as an economic and political power. With increased pressure on forestry resources, the forestry administration is determined to upscale sustainable forest management. This requires adhering to global notions of sustainability thorough market mechanisms and ensuring a degree of autonomy of forest management through localising processes. Secondly, China recently received Forest Stewardship Council (FSC) bamboo certification for some of the most intensively managed areas in the country. This has increased controversy amongst experts regarding the efficacy of the mechanism to truly bring about sustainable bamboo management. Thirdly, on a more global scale, one of the crucial issues with up-scaling bamboo management is the fact that there are over 1,200 species of bamboo, with three different rooting structures: monopodial (diffuse) sympodial (clumping), and amphodial (mixed) – which have distinct policy and management needs. Focusing purely on the large-scale, intensively managed, monopodial or treelike' stands in China would ignore the vast areas of small-scale, sympodial bamboo homesteads with issues regarding flowering and propagation of sterile species. Bamboo plantations in Africa, Latin America, and India are being developed, which require enabling policy and management mechanisms. With a global industry estimated at US$10bn, the implications of an inclusive and enabling frame for bamboo management could have wide ranging impacts for both natural resource management and livelihood development.

Full textAbstract:
The concept of Sustainable Forest Management (SFM) has been promoted in the past few decades all over the world. Non-industrial private forest (NIPF) owners play an important role in that aspect in the U.S. because of their number (about 16 millions), the size of forest land under their control (about half of all forest land in the continental US), and the dynamism of their population (increasing number of new owners). This study sought to better understand how NIPF owners come to a decision for adoption (or non-adoption) of SFM practices. We developed a theoretical model combining four theories (the Value-Belief-Norm theory, the Theory of Planned Behavior, the Elaboration Likelihood Model, and the Innovation-Diffusion Process) to explain NIPFâ s decision making. Using multivariate analyses, we determined which elements of the developed theoretical model were significant in explaining adoption of eight groups of practices. Overall, some of the most significant predictors of adoption we identified were technical assistance, motivations for owning land and the use of a written management plan. Particular attention was also directed toward the eventual relationship between education and adoption of SFM practices and it was found that NIPF owners who attended educational programs tended to be likely adopters compared to those who did not attend any educational program. Since SFM was not limited to the US, we also analyzed the concept of SFM with the same goals as in the US, but under a completely different context (socio-cultural, economic and ecologic) in Africa, through the community-based natural resource management (CBNRM) system. We used four case studies and focused on criteria such as participation, equity (both procedural and distributive, power devolution, trust, etc) to analyze how CBNRM works on the field, what lessons to take from the cases to better ensure the goal of sustainability of the resources.Ph.

Full textAbstract:
This study assessed the effectiveness of Malawi’s forestry regulatory regime towards achieving sustainable forest management (SFM). The main purpose was to examine the policy contexts and institutional conditions within Malawi that aim to generate effective SFM. The study involved a comprehensive literature review of policies, legislations, journals and government reports.
The study has revealed that Malawi has several forest regulatory frameworks that enshrine SFM concept. However, implementation of these frameworks has been a big issue due to poor coordination; and inadequate financial and human resources. Effectiveness of the forest regime to achieve SFM is associated with increased forest cover. In Malawi, the outcome indicators of the forest regime like increased forest cover and incomes have been declining instead of increasing. Therefore, Malawi’s forest regime has not been effective to achieve SFM. It is therefore, recommended to strengthen the capacity of forest administration institutions at central, regional and local levels.

Full textAbstract:
Changes in landscape pattern caused by changes in forest management, namely the Sustainable Forestry Initiative (SFI), and the implications of these structural changes on landscape processes were analyzed. Landscape structure was studied based upon the comparison of landscapes with different management histories. Ecological processes were analyzed based upon simulation of stand and landscape attributes of habitats for several vertebrate species and upon simulation of hydrological processes such as water and sediment yield. A methodology to integrate landscape and stand pattern and dynamics with landscape processes was developed for this work. It integrates a forest landscape structure model, several stand level growth and yield models, vertebrate habitat models, and a hydrological model. The comparisons among landscapes revealed that forest management has a strong influence on landscape structure. The SFI program increases fragmentation of the landscape indicated by the presence of more and smaller patches, more edges, more complex shapes, and less and smaller core areas. Traditional intensive and extensive management show comparable patterns characterized by high aggregation and connectivity. Landscapes managed according to the SFI program show higher Habitat Suitability Index (HSI) values for American woodcock, American beaver, wild turkey, fox squirrel, and gray squirrel. HSI is higher for pine warbler in the landscape not managed according to the SFI program. Downy woodpecker and barred owl present very reduced HSI values in either landscape. The SFI program induced fragmentation of the habitat of pine warbler and the establishment of narrow and elongated habitats in a network structure for the remaining species. Both patterns are determined by SMZs. The scenario representing management according to the SFI program presents higher sediment yield at the watershed level than the scenario representing management not according to the SFI program due to higher channel erosion related to the absence of buffer strips in the non-SFI scenario. In general, management according to the SFI program increases landscape diversity and evenness, habitat suitability for most species, potential vertebrate diversity, and provides habitat structure suitable for most species. This management also decreases sediment loss at the watershed level.

Full textAbstract:
Thesis (MDF)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Developing sustainable forests has been acknowledged to be important, not just as a way of averting deforestation and land degradation, but as another opportunity to contribute positively towards rural development, especially in sub-Saharan Africa. Forestry development has, however, not received the recognition it deserves. Its importance to economic development and its potential contribution have not been explicitly communicated and thus remain undervalued. The long rotations required for trees to mature, plus the associated risk from fires, pests and diseases has affected the sector’s ability to attract investment. In South Africa this reluctance is evident in both the public and private sectors alike. Access to finance for forestry remains a challenge, which negatively affects the supply to the processing part of the value chain. The objective of the study is to review current forestry funding mechanisms in South Africa, specifically plantations and their contributions to rural economic development. Using secondary data, the study reviewed the current sector funding from the state, development funding institutions and the private sector. The study also looked at alternative sources used in other countries and how they can be customised to the South African economy. In this study it was found that there are gaps between policies aimed at the development of the sector on the one hand, and the resources allocated to the sector on the other hand. The available schemes fail to support the sector policies’ objectives. These discrepancies can be attributed to the poor design of the current offering, the development of which failed to fully consider the dynamics of the sector. The conclusion of the study was that the government needs to play more of a leading role in developing the sector, especially with the small-scale growers who cannot be catered for by both commercial and development banks. The sector also stands to benefit significantly from better collaboration between the public and private sectors. Policies that create an enabling environment would also encourage the private sector to invest more. The study also suggested that, in view of the dynamics of the sector and its contribution to climate change risk mitigation, there is room to tap innovative funding such as that offered by environmental funding.

Full textAbstract:
Erosion is a serious concern across the US and the globe. One effective method to reduce soil erosion is to apply rolled erosion control products (RECPs). One material source for use in RECPs that has not been studied is low-value forest residuals (LVRs). The objectives of this study were to design RECPs out of four LVRs (leaf litter, willow whiplets, willow chips, spruce needles) and to assess their ability to reduce soil loss, control water quality (turbidity and total phosphorous), and enhance germination. LVR RECPs were tested using ASTM standards on bare, detritus, and burned soils. Leaf litter and spruce needle RECPs were highly effective at all three abilities, while the willow whiplet and chip RECPs were effective at reducing erosion, but less effective at controlling water quality and enhancing vegetation. Overall, the use of LVRs as a material source for RECPs shows great promise.

Full textAbstract:
The research concerns the potential for using the native plants of the Negev Desert in southern Israel in the Negev, which will help to promote more sustainable landscape development in the region. The study combines the data collection in the field of 163 plant species located in the Negev desert and the literature review of these species. The plants’ key physical, visual and aesthetic characteristics as well as their natural growing conditions are analysed. The analysis leads to an evaluation of the Negev plants in terms of suitability for particular uses in the Negev landscape. The conclusion reached is that the main reason for the non-use of the native plants is that they are still considered a part of the hostile desert environment. They have not as yet been ‘culturalised’. The advantages/disadvantages of using the native plant species is considered for each plant using a natural/quasi-experimental method, where each of the 163 species located by the author is analysed in terms of its physical and aesthetic characteristic and potential use. Furthermore, the individual species are matched with an exotic species and evaluated according to their potential landscape and ecological effects, water use and their potentials for environmental use in natural areas, the middle landscape and garden locations. The analysis and evaluation of the native Negev species confirms that 95%-96% of the native Negev plants have the potential for environmental use in natural areas and the middle landscape and 69% have the potential for garden use. A scientific study of the shade characteristics of 6 native Negev trees confirms that these trees provide an equal, if not better shade, compared to two control species and thus their potential for use in creating shade and altering micro-climate has been proven. The research also proposes a series of micro-landscape solutions, which will help to promote plant establishment and growth in the Negev as well as other desert environments. These proposals are seen as part of the agenda for establishing more sustainable landscape development in the Negev.

Full textAbstract:
This thesis has the aim of presenting a forest management system to be applied on small farms, especially in the settlement projects of the Brazilian Amazon, and to examine its sustainability by investigating the responses of the forest in terms of the changes in natural regeneration in felling gaps and the dynamics of the residual trees. Using the program CAFOGROM, an additional aim was to simulate the forest responses to different cycle lengths, harvesting intensities and silvicultural treatments to determine the theoretical optimum combination of these parameters. The proposed forest management system was designed to generate a new source of family income and to maintain the structure and biodiversity of the legal forest reserves. The system is new in three main characteristics: the use of short cycles in the management of tropical forest, the low harvesting intensity and environmental impact and the direct involvement of the local population in all forest management activities. It is based on a minimum felling cycle of ten years and an annual harvest of 5-10 m3 ha-1 of timber. The gaps produced by logging in PC Peixoto can be classified as small or less often medium sized (canopy openness from 10% to 25%). Differences in gap size and canopy openness produced significant differences in the growth rates, species richness and species diversity of seedlings, but no statistically significant differences could be determined according to the position of the quadrats in the gaps. Mortality rates increased and recruitment rates decreased with increasing gap size. The density and recruitment of seedlings of commercial species was not different between gap sizes, but gap creation increased the growth rate of the seedlings of these species.

Full textAbstract:
As the past century’s technological development has progressed the Swedish boreal forests have transformed into dense, highly productive, homogenous and coniferous forests. The area around Saxdalen in Ludvika municipality has long been dominated forests which have been heavily worked since the 18th century. There are in Ludvika 119 000 hectares of productive forest land. Around 70 percent are owned by forest companies and 20 by private forest owners. The forestry is governed by national laws and instructions from the Swedish Forest Agency. Foresters may also choose to abide by certification systems such as FSC and PEFC. 80 percent of Swedish productive forest is certified. This thesis is based on literature review and 8 field studies of regeneration fellings in Saxdalen. The purpose of this thesis is to understand to what degree environmental considerations are taken during regeneration fellings to preserve biodiversity. The focus of the thesis has been the preservation of storm sturdy trees, deciduous trees and standing dread trees, larger tree stumps and protected zones around watercourses. The protected zones were found severely lacking in practically all the observed fellings. The quality the trees preserved varied greatly between the fellings. In this study there were no found links between the ownership form or certification system and the considerations taken during regeneration fellings. A lot of parties are involved in fellings and those responsible aren’t always in full control. The work of preserving boreal forests resilience and biodiversity must be conducted in more strategic and coordinated fashion. There must be common criteria and strategies for large forest areas so that species can spread and survive the forestry, especially considering future climate change.

Full textAbstract:
This study develops and tests a method of intervention designed to incorporate the concept of sustainable development into management strategies for the natural tropical forest, in the particular case of forest exploitation by small-scale local sawmilling enterprises. Sustainable development is defined as a development process that satisfies jointly the goals of the biological, social and economic spheres of forest management. A review of orthodox management strategies suggested that they focus on maximizing benefits in only one or two of these spheres, and are inadequate to address the requirements of truly sustainable development. The stakeholder concept, adapted from modern corporate management theory, was identified as one model with the potential to satisfy the requirements of sustainable development. A management strategy based on stakeholder theory, termed the Integrated Management Approach (IMA), was developed for the case of locally-developed sawmilling enterprises dependent on the natural forest. The IMA is an iterative process based on the following steps: (1) the definition of criteria and the collection of information to describe the system as it was intended to operate (i.e., the Technical Limit of the operation) and as the enterprise is found at the time of initial intervention (i.e., the Benchmark Situation of the enterprise); (2) development of Negotiation Aims, based on the information collected, according to which the enterprise can progress towards the Technical Limits necessary for sustainable development; (3) identification of stakeholders and (4) their stakes in the enterprise; (5) assessment of stakeholder satisfaction, and negotiation from that basis towards the Negotiation Aims; (6) monitoring and iteration as necessary. Three East African sawmill enterprises were used as case studies to develop and test the IMA. The case studies exhibit many of the social, economic and biological conditions which have hindered successful implementation of traditional management systems to the natural tropical forest. The outcomes of the IMA process for each case study were compared in terms of the rating accorded criteria for each sphere and across spheres, and of the participation and satisfaction of stakeholders. In general, all parameters increased with successive iterations of the IMA, although a major change of attitude by one of the key stakeholders in the final iteration for one enterprise reversed many of the gains previously made, thereby demonstrating one of the limitations of the strategy. The results of this study suggest that the IMA has considerable potential to progress the objective of sustainable development for the case of local sawmilling enterprises operating under frontier conditions. They also suggest that the IMA should be applicable more generally, in facilitating sustainable development for a variety of enterprises based on natural resource use.

This research assesses the state of sustainability of State indigenous forests in the Eastern Cape and provides recommendations to improve their sustainability. The Eastern Cape Indigenous Forest Management Audit (ECIFMA) report of 2009 provided the primary data for this assessment (DAFF, 2009). The research was inspired by the fact that the global challenge of forestry destruction and degradation where the extent of forests is being reduced at an alarming rate of 6% annually. It became essential for global leaders to develop policies and strategies that sought to promote sustainable forest management. The monitoring of sustainability of forests was only possible through use of globally and nationally developed sets of criteria and indicators. Eleven forest estates responsible for the management of State indigenous forests in the Eastern Cape were selected for this research. The choice was influenced by the availability of audit data from the ECIFMA report of 2009. This report contained performance information of 41 indicators under 18 criteria for monitoring sustainable forest management as extracted from the PCI&S assessment checklist developed for monitoring the sustainability of indigenous forests in South Africa (DWAF, 2005). The data was refined using the MCA methods (ranking and scoring) as described by Mendoza and Prabhu (2000). These methods yielded to the determination of the performance of indicators of forest sustainability. It was thus important to conclude the research by responding to the following questions: • What is the state of sustainability of the State indigenous forests in the Eastern Cape? • What recommendations could be made to improve the sustainability of State indigenous forests? It was found that the State indigenous forests were not managed in a sustainable manner. The research report is concluded by providing concrete recommendations to improve forest sustainability.

Full textAbstract:
As the doubling time of the global human population decreases, increasing emphasis is placed on sustainable development by both policy makers and scientists. Sustainable forest management is one part of the overall picture of sustainable development. One method to assess sustainable forest management is through the use of criteria and indicators. Criteria represent sustainable management goals. Indicators are measurable quantities that designate whether the goals are being met. The maintenance of forest health and vitality is a criterion of the Montréal Process Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests. Measures of air pollution, forest disturbance, and change in ecological integrity provide indicators of how well forest health and vitality are being maintained. Using national databases, I assess air pollution in the United States, demonstrate the use of epidemiological approaches to examine forest disturbances, and develop an analytical technique to identify gaps and target priorities in reserve networks. The analyses in this dissertation offer new approaches to large-scale analysis of Montréal Process Criteria and Indicators. The results can be summarized as follows. (1) From 1994 through 2000 air pollution was highest in the northeastern United States and the oak-hickory and loblolly-shortleaf forest type groups were consistently exposed to more air pollution than other forest types. Conversely, the western white pine and larch forest type groups were consistently exposed to less air pollution than all other forest types. (2) Examination of the southeastern United States revealed high rates of forest fragmentation in the piedmont and coastal plain region. In the Pacific North west, insect and pathogen activity was analyzed and recurring clusters of high rates of activity were identified. (3) Although protected areas of the Douglas-fir forest type group occurred throughout much of the species range, most existed in colder and drier parts of the range. To conserve representative habitats, future conservation efforts would be most effective in warmer and wetter areas of western Oregon, northwestern Washington, and northwestern California.

Full textAbstract:
The original design of this dissertation project was relatively simple and straightforward. It was intended to produce one single, dynamic, classification and mapping system for existing vegetation that could rely on commonly available inventory and remote sensing data. This classification and mapping system was intended to provide the analytical basis for resource planning and management. The problems encountered during the first phase of the original design transformed this project into an extensive analysis of the nature of these problems and a decade-long remote sensing applications development endeavor. What evolved from this applications development process is a portion of what has become a "system of systems" to inform and support natural resource management. This dissertation presents the progression of work that sequentially developed a suite of remote sensing applications designed to address different aspects of the problems encountered with the original project. These remote sensing applications feature different resource issues, and resource components and are presented in separate chapters. Chapter one provides an introduction and description of the project evolution and chapter six provides a summary of the work and concluding discussion. Chapters two through five describe remote sensing applications that represent related, yet independent studies that are presented essentially as previously published. Chapter two evaluates different approaches to classifying and mapping fire severity using multi-temporal Landsat TM data. The recommended method currently represents the analytical basis for fire severity data produced by the USDA Forest Service and the US Geological Survey. Chapter three also uses multi-temporal Landsat data and compares quantitative, remote-sensing-based change detection methods for forest management related canopy change. The recommended method has been widely applied for a variety of forest health and disaster response applications. Chapter four presents a method for multi-source and multi-classifier regional land cover mapping that is currently incorporated in the USDA Forest Service Existing Vegetation Classification and Mapping Technical Guide. Chapter five presents a study using nearest neighbor imputation methods to generate geospatial data surfaces for simulation modeling of vegetation through time and space. While these results have not yet been successful enough to support widespread adoption and implementation, it is possible that these general methods can be adapted to perform adequately for simulation modeling data needs.

Full textAbstract:
Sustainable forest management is a key issue in Malawi. Malawi is a relatively small, resource poor, densely populated country, which in some areas is close to exceeding the energy capacity of the environment to support it. Despite the importance of forestry in Malawi, there is a severe lack of knowledge about the current state of Malawi’s forest resources. Remote sensing has the potential to provide current and historical insights into forest cover change. However, Malawi faces a number of key challenges with regards to in-country remote sensing. These include technical capacity for obtaining accurate and consistent forest area and biomass estimates, with errors at acceptable levels, as well as the necessary supporting capacity development for individuals and institutions. This thesis examines how remote sensing can be used to support sustainable forestry in Malawi, by assessing the use of both optical and Synthetic Aperture Radar (SAR) data for mapping forest cover, forest cover change and aboveground biomass (AGB). L-band SAR data was used to try and establish a relationship between radar backscatter and biomass, which has been achieved many times in other areas. However, no correlations between any field-based forest metric and backscatter explained enough of the variability in the datasets to be used to develop empirical relationships between the variables. There were also differences between my field measured AGB and AGB values predicted by a published backscatter-biomass relationship for African dry forests. The speckle inherent in SAR imagery, the heterogeneity of Malawi’s dominant miombo savanna, and Malawi’s variable topography are likely to have played a significant role in this. Two different MODIS products were investigated for their potential for mapping forest cover change, with regards to potential REDD+ schemes. As part of this, a published equation was used to calculate the break-even point for REDD+ schemes in Malawi, using estimates of forest area and deforestation for the United Nations Forest Resources Assessment 2010. The results of this equation show that measurement error is the most important factor in determining whether or not Malawi can make REDD+ economically viable, particularly at lower levels of deforestation. While neither of the MODIS products were able to produce a verifiable forest cover change map, they do confirm that Malawi is experiencing some level of forest loss, and help to narrow down the range of possible forest loss rates Malawi is experiencing to between 1-3% net forest loss per year. Finally, this thesis examines global trends in the engagement of developing country researchers with global academic remote sensing research, to investigate differences in in-country capacity for monitoring forests using remote sensing. The results of this found that while a significant proportion of Earth observation research (44%) has developing countries as their object of research, less than 3% of publications have authors working, or affiliated to, a developing country (excluding China, India and Brazil, which are not only countries in transition, but have well established EO capacity). These patterns appear consistent over the past 20 years, despite the increasing awareness of the importance of capacity development over this period. Despite inconclusive results from the approaches examined here, remote sensing can play a role in improving understanding about the dynamics of Malawi’s forest resources. There is a need for nationwide accurate, validated forest maps that can be repeated at least on a yearly basis, and remote sensing could produced these without the resources needed to conduct full national ground inventories each year. If remote sensing is to be useful as a forest mapping tool in Malawi, it needs to provide consistent, verifiable and updatable estimates of forest cover and biomass change. This ideally needs to be achieved using free or low cost data, and by using open source or open access software, as this will better enable incountry researchers to conduct on-going forest mapping activities.

ENGLISH ABSTRACT: A case study in miombo woodlands was carried out in Pindanganga and MOFLOR forest concession, Gondola and Dondo Districts respectively, in the centre of Mozambique, to analyse the impact of alternative forest management regimes and sectoral and extra sectoral policies on the well being of stakeholders and conservation of the woodlands. A system dynamics model, MIOMBOSIM, based on game theory and implemented in POWERSIM was developed. The analysis is based on a simulation model of the fluctuation over time of the human population, forest dynamics, harvesting costs of the private sector, household consumption, commercial outputs and prices (timber, charcoal, non timber forest products and domestic animals), using data from field surveys and the literature. It also simulated the effects over time of changes in charcoal production efficiency, sales amount and marketing prices of NTFPs, agricultural output prices, off-miombo greater employment availability and a combination between the changes (simultaneous increase in marketing prices ofNTFPs and agricultural output prices, simultaneous increase in charcoal production efficiency and agricultural output prices, and simultaneous increase in off-miombo greater employment availability and agricultural output prices). The modelling approach chosen allows to evaluate management regimes taking into account the different stakeholder interests, which are often conflicting. This study shows that improvement in the well being of stakeholders and resource conservation can be achieved with sound forest management practices. There is no management regime capable of fully satisfying the goals of the stakeholders. The cooperative management option is potentially beneficial to local communities if properly implemented and can improve the rural livelihoods and the woodland resources condition. It also shows that regulated forest management regimes incorporating social concerns or incorporating social and environmental concerns are potentially more beneficial to the household sector than the open access regime. Results found in the study show that an increase by 10% and 30% on charcoal production efficiency can lead to an increase in the per capita benefits of the household sector by 3.0 to more than 100%, but can not reach the poverty line (one dollar per day per person). An increase by 100% in the sales amount or 100% increase in market selling prices of NTFPs can lead to an increase in the per capita benefits of the household sector. An increase in agricultural output selling prices by 25% without any other incentive leads to agricultural expansion. An increase by 100% in off-miembo employment opportunities in the study areas has an insignificant impact on resource use and conservation for the local communities due to the very low employment opportunities currently in place (0.008% in Pindanganga and 0.005% in MOFLOR area). A combination of these two policies instruments under ceteris paribus condition can improve the well being of the rural communities depending on the management regime option, but can not reach the poverty line (one dollar per day per person). The ranking of the management regime can change depending on the policy instrument applied.
AFRIKAANSE OPSOMMING: 'n Gevalle-studie is in Miombo boomveld in Pindanganga en MOFLOR, onderskeidelik in die Gondola en Dondo Distrikte in die sentrale deel van Mosambiek, uitgevoer om die impak van alternatiewe bosbestuursisteme en sektorale en ekstra-sektorale beleide op die welstand van belanghebbendes (stakeholders) en bewaring van die boomveld te ontleed. 'n Sisteem-dinamika model, MIOMBOSIM, gebaseer op spel teorie (game theory) en ge-implementeer in POWERSIM, was ontwikkel. Die analise is gebaseer op 'n simulasie-model van die fluktuasie oor tyd van die plaaslike bevolking, bosdinamika, oestingskostes van die private sektor, huishoudelike verbruik, kommersiële uitsette en pryse (hout, houtskool, nie-hout produkte en huishoudelike diere), deur data van veldopnames en uit die literatuur te gebruik. Die invloede oor tyd in veranderinge in effektiwiteit van houtskoolproduksie, verkoopsvlakke en markpryse van nie-hout produkte, landbou uitsetpryse, beskikbare indiensneming buite die Miombo boomveldgebiede, en 'n kombinasie tussen die veranderinge, is ook gesimuleer. Die gekose modelleringsbenadering het dit moontlik gemaak om die bosbestuursisteme te evalueer met inagneming van die verskillende en dikwels teenstrydige behoeftes van die belanghebbendes. Die studie het getoon dat verbetering In die welstand van die belanghebbendes en hulpbronbewaring bereik kan word met gesonde bosbestuurspraktyke. Geeneen van die bosbestuursisteme kan die doelwitte van die belanghebbendes ten volle bevredig nie. Die kooperatiewe bestuursopsie is potensieel voordelig vir die plaaslike gemeeskappe indien behoorlik ge-implementeer, en kan die landelike lewensbestaan sowel as die toestand van die boomveld as hulpbron verbeter. Gereguleerde bosbestuursisteme wat sosiale belange of sosialeomgewingsbelange insluit, is potensieel meer voordelig vir die huishoudelike sektor as die vrye toegangsisteem (open access regime). Resultate van die studie het getoon dat 'n toename van onderskeidelik 10% and 30% in effektiwiteit van houtskoolproduksie kan lei tot 'n toename in per kapita voordele van die huishoudelike sektor van 3.0% tot meer as 100%, maar kan nie lei tot 'n vebetering bokant die armoedevlak nie (een VSA doller per dag per persoon). 'n Toename van 100% in die hoeveelheid verkope of 'n 100% toename in die markverkoopsprys van nie-hout produkte kan lei tot 'n toename in die per kapita voordele van die huishoudelike sektor. 'n Toename in die landbou uitsetverkoopspryse met 25% sonder enige ander insentiewe lei tot landbou-uitbreiding. 'n 100% Toename in indiensnemingsgeleenthede buite die Miombo boomveldgebiede in die studiegebiede het onbeduidende impakte op hulpbrongebruik en bewaring vir die plaaslike gemeenskappe as gevolg van baie lae huidige indiensnemingsgeleenthede (0.008% in Pindanganga en 0.005% in MOFLOR). 'n Kombinasie van die twee beleidsinstrumente onder toestande van ceteris paribus kan die welstand van die landelike gemeenskappe verbeter afhangende van die bestuursisteemopsie, maar kan nie die armoedsvlak oorskry nie (een VSA doller per dag per persoon). Die rangorde van die bestuursisteem kan verander afhangende van watter beleidsinstrument toegepas word.

Thesis (PhD (For))--Stellenbosch University, 2002.ENGLISH ABSTRACT: This study aims to evaluate the effects of forestry policy on the sustainability of forest resources in Southern Africa. However, the study has confirmed that forestry policy does not operate independently of other policies. Its scope is defined by overarching framework legislation and policy, while it functions within a complex mesh of crosscutting and sectoral policies. Therefore, the implications of these external policies for forest conservation have also been assessed. The method used employs predominantly qualitative assessment of documentary data, which constitute the main contents of the three case studies: South Africa, Tanzania and Zambia. This qualitative information has been transformed into quantitative data, using a scoring scale of one to five for certain indicators of sustainable forest management (SFM). The average score for each country makes up a forest conservation index (FCI), which provides a comprehensive insight into the performance of a country's forestry and other resource conservation policies. South Africa's FCI is estimated at 3, while Tanzania and Zambia's indices have been rounded to 2 each. As South Africa's forestry policy and other biological resource conservation policies came into existence as recent as the mid- and late 1990s, this index suggests that these policies will lead to SFM subject to satisfactory implementation. Indeed, South Africa has a congruous forestry legislation whose regulatory mechanisms are appropriately blended with financial and framework incentives. Its overarching framework legislation and policy define forestry policy, while the crosscutting policies reinforce it. However, the country's performance on intergovernmental and intersectoral policy co-ordination is poor, as well as on the economic valuation of its natural forest resources. Furthermore, the formulation of South Africa's forestry policy was not founded on up-to-date forest resource data. Contrary to the South African case, Tanzania and Zambia's indices indicate the likelihood of unsustainable forest use and management. These countries' existing forestry and other resource conservation policy-making processes are narrow-based and gender-insensitive, rendering them unpopular among policyaffected and policy-connected stakeholders. These inappropriate policies and their blunt instruments distort markets for forest resources, i.e., create situations in which benefits are dissociated from costs, prices from scarcities, rights from responsibilities and actions from consequences. Both forestry policies and their governing tools were not founded on contemporary forest resource data, i.e., they are not issue centred. The countries' framework laws have also failed to institutionalise environmental impact assessment, monitoring and evaluation, intersectoral policy co-ordination, participatory approaches to natural resource management and ownership of environmental assets such as land and forest resources by local communities. The administration of forestry policy requires competent professional and technical staff. South Africa has adequate human resources in the forestry sector, although the personnel appear to lack the necessary skills for participatory forest management for poverty reduction. Tanzania has adequate but ineffective forestry personnel, resutting in lack of law enforcement and corruption while Zambia lacks professional staff to interpret and implement the existing forestry policy. The ineffectiveness and the lack of professional and technical staff, inter alia, is reflected in the high rates of deforestation, which have been estimated at 91,000 halannum for Tanzania and 851,000 halannum for Zambia. Unlike South Africa, both Tanzania and Zambia's sectoral policies fail to cultivate concerns for forest conservation. This situation is aggravated further by the pervasive lack of intra- and intersectoral policy coordination among biological resource conservation divisions and departments. The coherence of South Africa's forestry and other resource conservation policies is attributable to the scarcity of natural forests in the country. Approximately, 7.0% of South Africa's landscape is under forest cover, while Tanzania and Zambia have 37% and 42%, respectively. Decreasing supplies of forest coupled with the increasing demands for forest resources causes the value of forest resources to appreciate. Naturally, there is a stronger need for the forest-scarce South Africa to pursue prudent conservation policies to protect its limited forest than Tanzania and Zambia whose governments treat their respective vast land and forest resources as a safety valve for economic hardship without adequate investment in SFM. In summary, forest resource use and management in Tanzania and Zambia are littered by market and policy failures. It is envisaged that the opportunities and constraints identified in each market and policy failure will inform future forestry and related policy-making process, not only in the concerned countries but also in other African countries experiencing similar forest conservation problems.
AFRIKAANSE OPSOMMING: Hierdie studie het ten doel om die effekte te evalueer wat bosboubeleid het op die volhoubaarheid van woudhulpbronne in Suidelike Afrika. Hierdie studie het egter bevestig dat bosboubeleid nie onafhanklik van ander beleidspunte funksioneer nie. Die omvang daarvan word gedefinieer deur oorkoepelende raamwerkwetgewing en beleid, terwyl dit binne 'n komplekse netwerk van oorkruisende en sektorale beleid funksioneer. Daaom is die implikasies van hierdie eksteme beleidspunte vir woudbewaring ook bepaal. Die metode gebruik, wend hoofsaaklik kwalitatiewe beraming van dokumentere data aan, wat die hoofinhoud van die drie gevallestudies, nl. Suid-Afrika, Tanzania en Zambia uitrnaak. Hierdie kwalitatiewe informasie is omvorm na kwantitatiewe data, deur gebruik te maak van 'n skaal van een tot vyf vir sekere indikators van vohoubae bosbestuur (VBB). Die gemiddelde punt vir elke land vorm 'n woudbewaringsindeks (WBI), wat 'n omvatlende insig verskaf van die land se uitvoering van die bosbou- en bewaringsbeleid van ander hulpbronne. Suid-Afrika se WBI is beraam op 3, terwyl Tanzania en Zambia sa indekse elk tot 2 afgerond is. Siende dat Suid-Afrika se bosbou- en bewainqsoeleld van ander biologiese hulpbronne eers so onlangs as die middel- en laat 1990's in werking getree het, stel hierdie indeks voor dat die beleid sal lei tot VBB, onderhewig aan bevredigende uitvoering daarvan. Suid-Afrika het inderdaad 'n gepaste bosboubeleid, waarvan die regulerende meganismes toepaslik vermeng is met finensiele en raamwerk aansporings. Die oorkoepelende raamwerkwetgewing en beleid definieer bosboubeleid, terwyl oorkruisende beleidspunte dit versterk. Die land se uitvoering van interregerings- en intersektorale beleidkoordinasie, is egter swak, asook in die ekonomiesa waardering van sy natuurlike woudhulpbronne. Verder, is die formulering van Suid-Afrika se bosboubeleid nie gegrond op woudhulpbrondata wat op hoogte was nie. In teenstelling met die Suid-Afrikaanse geval, toon die indeksa van Tanzania en Zcrnbia die waCl'skynlikheid van onvomoubae bosbenutting en -bestuur. Hierdie lande se bestaande beleidvormingsprosasse vir bosbou en bewaring van ander hulpbronne, is eng-gebaseer en geslags-onsensitief, wat dit onpopulsr maak onder beleidgeaffekteerde en beleidverbonde insethouers. Hierdie ontoepaslike beleidspunte en stomp instrumente verdraai markte vir woudhulpbronne, d.i. skep situasies waarin voordele gedissosieer is van kostes, pryse van skaashed, regte van verantwoordelikhede en aksies van nagevolge. Beide bosboubeleidspunte en die leidingsinstrumente is nie gegrond op kontemporere woudhulpbrondata nie, d.w.s. hulle is nie rondom die kwessie gesentreer nie. Die lande se raamwerkwette het ook gefaal daarin om omgewingsimpakberamings, monitering en evaluering, intersektorale beleidkoordinering, deelnemende benaderings tot natuurlike hulpbronbestuur en plaaslike gemeenskappe sa eienaaskai van omgewingsbates, SODS grond en woudhulpbronne in te stel. Die administrasie van bosboubeleid verg bevoegde professionele en tegniese personeel. Sui-Afrika het voldoende menslike hulpbronne in die bosbousektor, hoewel dit voorkom of die personeel nie die nodige vaadiqhede het vir deelnemende bosbestuur vir die veligting van arnoede nie. Tanzanie het voldoende, maa oneffektiewe bosboupersoneel, wat 'n gebrek aan wetstoepassing en korrupsie tot gevolg het, terwyl Zambie 'n tekort het aan professionele personeel om die bestaande bosboubeleid te interpreteer en te implementeer. Die oneffektiwiteit en die gebrek aan professionele en tegniese personeel, onder andere, word gerefiekteer in die hoe tempo van ontbossing, wat beraam is op 91,000 ha/jaCl'vir Tenzenie en 851,000 ha/jaCl'vir Zembie. Anders as Suid-Afrika, faal beide Tanzanie en Zambia se sektorale beleidspunte daain om belange vir woudbewaring te kweek. Hierdie situasie word verder vererger deur die deurdringende gebrek aan intra- en intersektorale beleidkoordinering onder afdelings en departemente van biologiese hulpbronbewaring. Die verband tussen Suid-Afrika se bosbou- en bewaringsbeleid van ander hulpbronne word toegeskryf aan die skaarsheid van natuurlike woude in die land. Ongeveer 7.0% van die Suid-Afrikaanse landskap is bedek met woude, terwyl Tanzanie en Zambia onderskeidelik 37% en 42% bedek is. Verlaagde voorraad van woude, gepaard met die toenemende vraag na woudhulpbronne, het tot gevolg dat die waade van woudhulpbronne styg. Natuurlik is daar 'n groter behoefte vir die woud-arm Suid-Afrika om verstandige bewaingsbeleid na te streef om sy beperkte woude te beskerm as Tanzanie en Zambie, waa hulle regerings hul onderskeie ge\Yeldigegrond en woudhulpbronne behandel as 'n veiligheidsklep vir ekonomiese ontbering, sonder voldoende belegging in VBB. As opsomming, is die benutting en bestuur van woudhulpbronne in Tanzania en Zambia met mark- en beleidsmislukking besaai. Dit word beoog dat die geleenthede en beperkinge wat met elke mark- en beleidsmislukking ge'identifiseer is, toekomstige bosbou en verwante beleidvormingsproses kan inlig, nie net in die betrokke lande nie, maar ook in ander Afrika lande wat soortgelyke woudbewarings probleme ondervind.

Full textAbstract:
This thesis is an examination of the political settlement in Indian forest policy. In the last two decades the rapid degradation of Indian forests has led to a reconsideration of who should manage the forests and with what priorities. An agenda has emerged which identifies the decentralisation of resources to local communities for subsistence as a national priority. This thesis explores the content and development of the consensus over decentralised forest management. My focus in this respect is on a system of common property forest management in the Central Himalaya, and on two villages in District Kurnaun in particular. In chapter 1 argue that the content of agenda is determined by two interest groups, the government and 'a social forestry interest group', comprised of NGOs ahd the international development community. Both have theories about the interaction between environment and society in which their own specific interests are represented as being in the general interest of society as a whole. The 'conventional' position adopted by the government considers central control over local units of management necessary to prevent unrestrained resource use. The 'populist' position of the social forestry interest group maintains that common property regimes were a past tradition, and that their disruption - is a principle cause for deforestation. Both theories fail to explore the material causes for environmental degradation, and the way in which local communities have adapted their patterns of resource use and social relations of production in response to developments in the wider economy. In chapter 3, 5, 6 and 7 I show the inadequacies of populist and conventional explanations for the interaction between environment and society, and why the new agenda fails to offer a comprehensive agenda for development. In chapter 4 and 8 I consider the way in which the discourse over the environment has become entrenched in policy making.
