Abstract:
Using a landscape simulation model, we examined ecological and economic implications of forest policies designed to emulate the historical fire regime across the 2 × 106 ha Oregon Coast Range. Simulated policies included two variants of the current policy and three policies reflecting aspects of the historical fire regime. Policy development was guided by the management intentions of four owner groups: forest industry, nonindustrial private, state, and federal. Fire severity was emulated with green-tree retention standards; fire frequency was emulated with annual harvestable area restrictions; and fire extent was emulated with harvest-unit size regulations. Simulated disturbance-based policies produced age-class distributions closer to the estimated historical range than those created by the current policy. Within 100 years, proportions of younger forests were within the historical range, while older forests moved closer to, but remained below, historical conditions. In the near term, disturbance-based policies produced annual harvest volumes 20%–60% lower than those produced by the current policy. However, relative costs of disturbance-based policies diminished over time. Our results suggest that if expediting a return to historical age-class distributions at a provincial-scale was a goal, then public lands would be needed to provide large patches of old forest. In addition, this experiment illustrated that distributing costs and benefits of conservation policies equitably across multiple private landowners is a significant challenge.

Abstract:
Abstract Forest management is a scientific discipline designed to develop methods of maintaining forest areas and to ensure the sustainable development of forest resources in terms and conditions of multifunctional forestry. This is a branch of practical forestry which deals with inventorying and assessing the state of forests, defines economic tasks and draws up a program of nature conservation for forest districts. The paper presents legal conditions related to the concept of forest management plan, as well as issues related to the area division, planning economic indications and their role for the forest environment. Authors present a forecast of impact of a forest management plan on the forest environment and the Natura 2000 sites.

Abstract:
The article deals with economic aspects of sustainable forest management. The analysis stems from Plíva’s typological system. Several hundreds of variants were calculated for forest silviculture profitability classified according to management intensity, target management system, proportion of ameliorating and improving species, proportion of natural regeneration, and set of forest types. The results show a possibility of labour saving and also marked differentiation of the effect of wood production function depending on natural and production conditions and management intensity.

Abstract:
A traditional approach to problems of the opening-up of forests has been based primarily on technical and economic aspects. It results particularly from the ground configuration and calculations of minimum costs for logging and transport operations. Optimum density of main forest roads is determined by a minimum value of the summary curve of costs of forest road construction and timber skidding. A new conception from the aspect of integrated forest management taking into account forest functions is based on a standard approach when technical and economic aspects are complemented by the particular functions of the forest. Thus, the technical and economic approach is changed to a technical-economic-environmental conception that will contribute to a reduction in negative effects of the construction of forest road network on the environment.

Abstract:
Abstract The special forest products industry has recently become an important factor in forest management. Plants common to the understories of many Pacific Northwest United States and coastal British Columbia forests are harvested, processed, and marketed worldwide in floral greens markets as supplements and complements in floral arrangements. The industry employed over 10,000 people in Washington, Oregon, and southern British Columbia in 1989, and generated an estimated $128.5 million in sales. Forestland managers are discovering the advantages associated with leasing harvesting rights to the producers and harvesters of these products. A mail survey was used to sample special forest products businesses in Washington, Oregon, and British Columbia during 1989. Descriptions of plant materials harvested and their value are presented and discussed. Business characteristics and total industry affects are discussed. The industry's impacts on the regional economies and the industries marketing strategies including channels of distribution, product development, market product development, and future market opportunities are also discussed.

Abstract:
Abstract In a stand managed for timber production, increased crown dieback and mortality of trees generally signal a need for reevaluating site conditions, management objectives, and harvesting practices. In this paper, we describe a case study of a northern hardwood forest stand intended for timber production but showing crown dieback and mortality. Plans for a diameter-limit cut were confounded by the presence of diseased and poor quality trees (especially sugar maples), a history of high-grading, and fair to poor site characteristics for sugar maple growth over much of the area. After evaluating the site, we suggested a revised management plan including a shelterwood cut favoring regeneration of both yellow birch and sugar maple. Forest management decisions based on ecological and economic considerations can promote both the long-term health and productivity of forest stands. However, management for long-term health and productivity are not likely to be accomplished under current market conditions in much of New England. North. J. Appl. For. 12(3):121-126.

Abstract:
Abstract Advancements in forest nursery management practices are directly tied to the value of the seeds used. When seed value is low and seeds are plentiful (as with wild seeds), old nursery practices that produce 5 plantable seedlings for 10 pure live seeds sown may be economically acceptable.However, with genetically improved seeds having a present value of 2 to 10 cents per seed, better nursery practices must be employed to provide optimum seed utilization. At some nurseries that produce 25 million seedlings and with seed costs of 0.5 cents per pure live seed, increasing nurseryseed efficiency by 10% could result in saving more than $20,000 annually. Also, if increasing nursery seed efficiency results in planting an additional 3,500 acres with improved seedlings, the increase in present value of future volume gains could easily amount to $90,000 peryear. To achieve the goal of producing 8 to 9 seedlings for every 10 pure live seeds sown, forest nurseries must have adequate funding to maintain the best personnel and equipment. South. J. Appl.

Abstract:
The objective of the paper is to establish an economic result of the management of forest stand under a selection system as exemplified on a model subcompartment. A qualitative research of tree species occurring in Subcompartment 116 D <br />at the Training Forest Enterprise (TFE) was made for this purpose. Cost and yield models of management were constructed and expected model costs and yields were calculated to establish a model economic result for the subcompartment. The models are entered actual data related to the general principles of management, to the volume of implemented silvicultural operations, and to the production capacity of the site. The volume of logging operations is based on a model decennial allowable cut and its assortment structure. A starting point for the establishment of costs are prices of concrete works set up by the TFE for the year 2004. Yields are calculated on the basis of average prices for raw timber assortments published by the Czech Statistical Office for the period from January to April 2004.

Abstract:
AbstractThis paper puts into relief the religious dimension of the fierce fight over the federal forests in Oregon. My purpose is to describe and comment on some of the religiously based normative pictures that underlie the institutional dynamics of the dispute. Oregon's religious contours are sketched as backdrop. Strands of civil religion Oregon style are teased out. Oregon Lutheran and Catholic visions are examined. Based on field observations, interviews and analysis of public documents, the essay finds a vital, though marginalised, religious dimension to the debate. Yet, moral vocabularies of a religious nature, evident in the personal convictions of forest debate participants, tend to drop out in public discourse, especially at the level of policy. While preserving the Enlightenment critique of religion, I argue, religion should be brought back in to the public square to give voice to religious persons and groups. Citizens and national forest policy makers must create the conditions in which religious voices are heard along with biological and economic ones. Not doing so violates a fundamental principle of political liberalism: inclusion. Suggestions are made as to how public debates, which include religious voices, might proceed.

Abstract:
The article considers the possibilities of developing forest entrepreneurship through expanding the range of ecosystem services and organizing sequestration Inustry on forest lands. The new type of forest management is based on the ability to balance carbon dioxide emissions into the atmosphere. The economic aspects of creating and using forest carbon farms are considered. To determine the standard costs for creating poplar and pine carbon plantations, the standard method was used. Creating carbon farms on forest land is a costly process, but carbon storage activities can bring numerous economic and environmental effects in addition to maintaining the carbon balance. The cost of creating one hectare of forest carbon farm is from 262 to 304 thousand rubles, while the economic effect of their use can significantly exceed the investment. The first stage in the organization of carbon farms should be the creation of test plantations-carbon polygons. It is proved that the necessary resources and prerequisites are available for the implementation of the actual practice-oriented task of creating carbon polygons in the Voronezh region.

Full text
Abstract:
Portland, OR, is the site of a unique urban food cart phenomenon that provides opportunities for small business ownership and access points for culturally specific food for the city's foreign-born and minority populations. Known as a "foodie haven," Portland also has an active sustainable food movement with engaged citizens and support from city and regional policies aimed at significantly increasing the consumption of local food. To date, there have been no in-depth studies on the sourcing habits of Portland food cart owners and whether or not these street-level actors are involved in the area's local alternative food movements (AFNs). The current understanding of the Portland food cart phenomenon is based on studies that have focused on carts and pods located in the central business district and "inner-ring" areas of the city. Areas beyond these locations (defined as Eastern Portland) are currently home to the majority of the city's growing foreign-born and minority populations. This thesis uses a situational analysis framework to explore the food supply practices of ethnic food cart owners operating in Eastern Portland cart pods. I investigate the feasibility of purchasing locally grown ingredients for use in ethnic cuisines and the degree to which cart owners incorporate the region's prevailing locavore ethics into their everyday culinary practices. Findings from this inquiry suggest that ethnic cart owners in Eastern Portland have a range of habitus, or personal dispositions and embodied knowledge, that is reflected in how they perceive the benefits of and barriers to "buying local" and the extent (if any) that they engage with AFNs in the Portland area. I assert that ethnic food cart owners in Eastern Portland are performing multiple community roles by providing access points for culturally specific cuisines for their particular ethnic groups, while also offering exotic experiences to other residents and tourists alike. I discuss variations within the food cart phenomenon itself by highlighting the differences in design, amenities, types of access, and neighborhood customer bases of cart pods located in Eastern Portland. Finally, I discuss future research directions for understanding the dynamics of food supply chains in small-scale, direct-to-vendor relationships and the implications for local and regional food sustainability policy goals.

Abstract:

The conflict in the Pacific Northwest between competing visions of how federal forests should be managed resulted in a political stalemate in the early 1990s. The Northwest Forest Plan (NWFP) was initiated to resolve the demands for maintaining ecosystem processes and biological diversity with the social and economic needs for timber harvest. The foundation for the plan rested with the development of ecosystem management. The intent of this research is to explore the events which led up to the adoption of the NWFP, how it was implemented by the US Forest Service and Bureau of Land Management and the subsequent reactions to and consequences of the plan.

The primary research consisted of thirty-eight semi-structured interviews with individuals responsible for the development of the initial plan, those tasked with implementing the plan and current federal agency personnel from the land management agencies and regulatory agencies. With the use of thematic analysis, key meanings were captured as expressed by the interviewees. The data was analyzed using institutional theory, capturing the organizational relations within the organizational field of the land management agencies.

Research findings suggest that the NWFP was unsuccessful in meeting the goal of addressing the social and economic issues as well as the goals for ecosystem management. This dissertation explores the organizational practices and cultural meanings that led to the final instantiation of the plan. It seeks to shed light on the reasons why these goals were not met and how future forest plans can move beyond the current stalemate between conservation and preservation.

Abstract:
Government funding for silviculture in British Columbia has expanded recently, but remains well short of the level recommended by many foresters. This thesis contains a proposal to replace government funding with investment from capital markets. It describes the funding mechanism, analyzes the implications to government, and introduces a method of distributing investment funds through a system of competitive bidding between forest management companies. In return for their participation, investors and forest companies would both receive equity in future timber production. The thesis concludes that at a cost of foregoing 50% of its future stumpage revenue, government might replace its current spending on intensive forest management with a funding level from capital markets of $500 million to $800 million per year.

Abstract:
The aim of the research is to quantify the HIV prevalence in human resources of forestry contracting businesses and to develop a management framework to promote economic sustainability of forestry contractors. HIV tests were conducted in the forest industry on the employees of contracting concerns from 2002/2003 to 2004/2005 with an accompanying questionnaire to collect demographic data. The HIV test results were analyzed with the demographic data to determine relationships between HIV prevalence and demographic factors. Contractors responded to a questionnaire on the effect of HIV and AIDS prevalence on (their) contracting businesses. The questionnaire also collected information about HIV and AIDS interventions and assistance to HIV and AIDS affected employees. Key stakeholders of other forestry sub-sectors were interviewed to facilitate comparison of the different sub-sectors and to establish if there were major differences between the sub-sectors, however, the focus was on the human resources of the forestry contracting sub-sector. The research results indicated that the HIV prevalence was increasing for the research period and was, in some regions, exceeding 40 per cent. The highest prevalence was recorded in the Highveld and Zululand regions and the lowest prevalence in the North-Eastern Cape. The HIV prevalence for females was constantly higher than the incidence for males and the ratio of males to females (all regions) approximated 68 per cent to 32 per cent. The high prevalence of HIV results in major social and economic impacts. The economic impact is aggravated through regulation (due to perceived market failure) and a bid for more equal distribution of wealth in the economy. The result of the sum of the impacts alludes to a conversion from labour to capital; however, to make well-informed decisions, various scenarios should be simulated to establish the optimum labour to capital ratio. The research further established that appropriate staffing is increasingly difficult and that the development of human capital is under pressure due to the high prevalence of HIV and AIDS. HIV and AIDS mitigation programmes will make a significant contribution to the return on human capital assets, as the economic life and productivity of such assets will be enhanced by such interventions. The management framework developed was assessed to be visually acceptable and useful by domain experts; however, to realise the full potential of the framework it should be used with anticipation of the research results regarding prevalence and future estimated AIDS releases and in conjunction with industry cost simulation models.

Hood, Paula Elizabeth. "Effects of Selective Logging and Roads on Instream Fine Sediments and Macroinvertebrate Assemblages in the Clackamas Basin, Oregon." PDXScholar, 2015. https://pdxscholar.library.pdx.edu/open_access_etds/2407.

Full text
Abstract:
Logging and associated skid trails, haul routes, and roads can have significant impacts on the magnitude and timing of sediments in streams in forested watersheds. Loss of vegetation, soil compaction, use of heavy logging equipment, and alteration of natural hydrologic patterns within the watershed can increase landslide rates, create erosion, and generate fine sediments. Selective logging, also called thinning, is a logging practice that leaves some trees within sale units unharvested. The ecological impacts of thinning on stream ecosystems are not fully understood and need further study. My hypothesis was that macroinvertebrate assemblages would be different in streams in non-reference areas that contain recent selective logging compared to streams in reference areas, and in downstream vs. upstream of selective logging units. I also hypothesized that selective logging and high road densities would be associated with increased instream fine sediments. I sampled water quality parameters and macroinvertebrates in three managed and three reference streams in the Clackamas River Basin during the field season of 2013. Turbidity, temperature, dissolved oxygen, conductivity, total dissolved solids (TDS), suspended sediment concentrations (SSC), and flow were sampled at each stream on four occasions during spring through early fall. Macroinvertebrates were sampled once in late summer or early fall. EPA rapid habitat assessments, canopy cover, pebble counts, embeddedness, and slope were also determined. Water quality parameters and macroinvertebrate indices in reference and non-reference sites were compared using t-tests, Welch's tests, or rank based equivalents. Macroinvertebrate assemblage patterns and associated environmental variables were characterized using non-metric multidimensional scaling (NMDS) ordination plots and envfit overlays. Macroinvertebrates had higher abundance and taxa richness in non-reference streams, and indices suggested poorer water quality in non-reference streams. Non-reference streams had a lower percentage of shredders and a higher portion of gatherer-collectors. Associations between land use, fine sediments, and changes in macroinvertebrate metrics and community assemblages were apparent at the reference vs. non-reference scale. It is likely that macroinvertebrates are responding, at least in part, to past logging and high road densities in non-reference streams. Fewer indications were found that recent logging may be affecting water quality and macroinvertebrates. Pearson's correlation coefficients show that the percent of recent logging upstream of study sites was correlated with several measures of fine sediments, suggesting that recent land use may be affecting sediment levels at the subwatershed scale. Stream temperatures increased from upstream to downstream in non-reference sites. Though no continual stream temperature data were collected in this study, the history of continuing temperature standard exceedances in the area suggest that further investigation of how selective logging may be affecting stream temperature and other water quality parameters in the Clackamas Basin is warranted. No other differences in water quality parameters were found from upstream to downstream, possibly because water quality was sufficiently protected, or because signals from land use impacts may be obscured by a several factors, including upstream confounding factors such as roads and past logging, and natural variability.

Full text
Abstract:
This study provides an analysis of watershed response to climate change and forest fire impacts, to better understand the hydrologic budget and inform water management decisions for present and future needs. The study site is 2,365 km2, located in the upper Umatilla River Basin (URB) in northeastern Oregon. The Precipitation Runoff Modeling System, a distributed-parameter, physical-process watershed model, was used in this study. Model calibration yielded a Nash Sutcliffe Model Efficiency of 0.73 for both calibration (1995-2010) and validation (2010-2014) of daily streamflow. Ten Global Climate Models using Coupled Model Intercomparison Project Phase 5 experiments with Representative Concentration Pathways 4.5 and 8.5 (RCP), were used to observe hydrologic regime shifts in the 2020s, 2050s, and 2080s. Mean center timing of flow occurs earlier in the year in both pre- and post-fire conditions, where there are increased winter flows and decreased summer flows throughout the 21st century. Change in temperature and percent change in precipitation is more variable in the summer than winter increasing over time, with a slight decrease in winter precipitation in the 2080s in RCP 8.5. Temperature increases 1.6°C in RCP 4.5 and 3.3°C in RCP 8.5 by the end of the 21st century. The ratio of Snow Water Equivalent to Precipitation decreases 96% in the 2080s in RCP 8.5 before forest cover reduction, and decreases 90-99% after forest cover reduction. Potential basin recharge and the base-flow index are both sustained throughout the 21st century with slight declines before forest cover reduction, with an increase in basin recharge and increase in base-flows in the 2080s after fire-burns. However, the simulated sustained base-flows and area-weighted basin recharge in this study, do not take into account the complex geologic structure of the Columbia River Basalt Group (CRBG). A more robust characterization and simulation of URB aquifer recharge would involve coupling the PRMS model with a groundwater model in a future study. Although groundwater recharge in the CRBG in the URB is not well understood, the long-term decline of groundwater storage presents a serious environmental challenge for the Confederated Tribes of the Umatilla Indian Reservation and communities in the URB.

Full text
Abstract:
Humans make decisions within ecosystems to enhance their well-being, but choices can lead to unintended consequences. The ecosystem services (ES) approach supports decision-making that considers all environmental goods and services. Many challenges remain in the implementation of the ES approach like how specific ES vary through space and time. We address this research problem using the Tualatin and Yamhill river basins in northwestern Oregon as a study area. Freshwater ES are quantified and mapped with the spatially-explicit ES modeling tool, Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST). In chapter II, we develop a simple urban land cover change modeling approach with selected stakeholder input. The products of this analysis are used in part to answer the question of how the freshwater ES of water yield, nutrient retention, and sediment retention will change in the future, and how their distribution potentially will change? In chapter III, these ES are modeled in InVEST using the land cover scenarios and three downscaled global climate models. The base period is 1981 to 2010 and the future period is 2036 to 2065. The models are calibrated to empirical estimates, and display different sensitivities to inputs. Water yield increases with higher rainfall but decreases with the highest temperature scenario. Nutrient export and retention estimates are positively correlated. In the Tualatin basin, more urban lands generally lead to increases in nutrient exports and retention. The effect is reversed in the Yamhill basin from much larger agricultural exports. Sediment exports and retention increase with higher winter rainfall but are negatively spatially correlated due to topographic effects. Simulation of a landscape scale installation of riparian buffers leads to decreases in exports and increases in retention. The distribution of the provision of freshwater ES remains unchanged throughout the scenarios. With few parameters in each InVEST model, all display a high degree of sensitivity. Parameterization is subject to high uncertainty even with calibrated values. We discuss the assumptions and limitations of InVEST's freshwater models. The spatially explicit nature of InVEST is its main advantage. This work coupled with other analyses in the study area can facilitate the identification of tradeoffs amongst ES leading to better ecosystem management.

<i>Abstract.</i>—Fish assemblages in the Willamette River basin (Oregon) were once substantially degraded by water pollution, channelization, dams, nonnative fish, and conversion of natural forest and savanna to agriculture and urbanization. Restoration actions have included basinwide waste treatment, physical habitat rehabilitation, recovery of the Oregon Chub <i>Oregonichthys crameri</i> to stable status, and stocking reductions of nonnative fish to protect native fish. State and federal sewage treatment regulations and funding, federal endangered species regulations and funding, and reduced funding and support for stocking nonnative trout led to those rehabilitated fish assemblages. Periodic fish and habitat monitoring has documented the following improvements in fish assemblages: (1) decreased occurrences of pollution-tolerant species and increased occurrences of pollution-sensitive species and native main-stem species, (2) increased number of abundant Oregon Chub populations, and (3) persistence of resident native Rainbow Trout <i>Oncorhynchus mykiss</i>. Notably, no known extinctions of native fish species have occurred in the Willamette River, water quality index scores in the lower river have improved from poor to fair, and water quality in the upper river remains good to excellent. In conclusion, enactment of laws and regulations for environmental protection and the collective actions of state and federal agencies, tribes, municipal governments, universities, land trusts and conservation groups, watershed councils, and private landowners have led to a substantially rehabilitated river. However, population and economic growth, climate change, nonnative fish, winter steelhead (anadromous Rainbow Trout) and spring Chinook Salmon <i>O. tshawytscha</i> listings, a superfund site, channel alterations, toxic substances, poor fish passage at dams, and altered flow regimes remain challenges. Four lessons learned are that (1) pollution control and improved water quality and flows are essential to the recovery and persistence of native fish populations, (2) recovery of endangered species is achievable but requires knowledge of their life history needs, (3) the greater ecological fitness of native stocks facilitates their persistence, and (4) research and monitoring, combined with public communication and collaboration, are essential for habitat and native fish assemblage rehabilitation.

Abstract:
This chapter discusses digital mechanisms for optimizing the management system in the forest industry, which includes organizational, legal, socio-economic, and environmental aspects. Efficient forest management is considered as an integral part of efficient nature management and includes the use of forest resources, their protection, and reproduction of forests. Digital management mechanisms in forest management in general and in the forest industry in particular are based on platform solutions. Platform solutions are based on the formation and processing of data on the basis of a single automated information system, which acts as the foundation for the development of digitalization in forestry. Such a digital platform is designed to provide informational, analytical, consulting, and other support to the activities of all subjects of relations in the field of use, conservation, protection, and reproduction of forest resources.

Abstract:
The Western Himalayan zone of India is not only threatened by rapid climatic changes, natural floods, and fires, but also by anthropogenic activities. Himalayan forests are vulnerable due to climatic changes and faced severe ecological deterioration due to anthropogenic pressures. The degradation of forests due to anthropogenic disturbances is increasing because of overgrowth of population, high poverty ratio, as well as the limitations of alternative livelihood options. Further resources from forest makes it inseparable to manage forest stands without considering the importance of socio-economic status and ecological aspects of forest management to the well-being of local communities. Therefore, the Himalayan forests and the communities depending on forests should be seen as a part of an evolving. This chapter will explore the vulnerability of the knowledge towards Western Himalayan forests and community-based management of forests. Additionally, it will sketch potential sites affected through anthropogenic pressures.

Abstract:
Emergencies are most probably the most important issue at the European and, of course, at the international level, in terms of impact to the economic structures, the ecosystems,and human and environmental resources. A number of emergencies have been identified within the Emergency Management Area and the areas under EMA coverage. These could be summarised as forest fires, chemical fires, structural fires, industrial accidents, oil and chemical spills, explosions, nuclear accidents, radiation, storms, tornadoes, floods, dam ruptures, marine algal blooms, avalanches, landslides, earthquakes, seismic waves, and volcanic eruptions. The modelling and simulation of the environmental hazards in Europe should be harmonised in a way where developments will proceed, through a consensus mechanism, between the industry, the users, and the standardisation organisations, to create a consensus approach by identifying best practice cases in the management (including detection surveillance and monitoring of the emergency), and to plan operational aspects of the emergency situations, identify proper technological breakthroughs, and identify techniques and developments.

Abstract:
‘Land degradation’ means the reduction and loss of the biological or economic productivity caused by land use change or by a physical process or a combination of the two. ‘Land’ means the terrestrial bio-productive system that comprises soil, vegetation, and other biota and the ecological and hydrological processes that operate within the system (UNEP 1992). The main components of land degradation are ecological degradation, soil loss, and reduction in the amount and quality of the available water resources for human survival and economic sustainability. Conacher and Sala (1998) have edited a major volume on land degradation in Mediterranean environments of the world and soil erosion mechanisms and water resources are considered in other chapters of this book (Chapters 6 and 21). This chapter will focus on the ecological aspects of land degradation by exploring some of the interactions between land use change, vegetation dynamics, grazing patterns, and wildfires. This chapter will also try to identify and avoid repeating the myths that abound in the more popular and/or politically motivated accounts of Mediterranean land degradation. Because of the complex spatial mosaic of environmental and cultural conditions across the Mediterranean (see Blondel 2006), it is not simple to identify the causes or main controls of land degradation or the management strategies required to combat degradation (Lesschen et al. 2007; Märker et al. 2008). As discussed in the context of lake sediment records in Chapter 9, it is certain that the origins of land degradation extend far back into prehistory. Indeed, Naveh and Dan (1973) have proposed a seven-phase history of land degradation for the Mediterranean basin, paraphrased thus: Phase 1 was the Lower Palaeolithic (around 1,000,000 to 100,000 years BP), when the Levant was the main route of biotic and hominid dispersal from Africa to Eurasia and later westwards through the Mediterranean basin. Hunting and gathering were the main activities and the populations were probably very low. Human impact on the environment is not known—but land degradation is assumed to have been negligible. After this, in Phase 2, it is argued that the use of fire as a tool for the opening up of dense forest spread westwards from Greece, possibly reaching France as early as 400,000 BP.

Abstract:
В трансформационный период России система государственного управления лесным хозяйством неоднократно реформировалась административными методами, при этом экономические методы управления и экономическое обоснование принимаемых решений до настоящего времени не нашло должного применения. В лесном секторе, включающем государственное управление лесами, лесное хозяйство и отрасли лесной промышленности, возникают новые проблемы формирования взаимовыгодных экономических отношений между государством, собственником лесного фонда, бизнесом в лесопользовании, населением, проживающим на лесных территориях или вблизи лесов. Совершенствование финансовоэкономического механизма национальной лесной политики должно быть направлено на реализацию социально-экологи-экономических целей устойчивого развития государства и его территорий. Лесное законодательство и документы стратегического планирования за 20‑летний период неоднократно пересматривались, что создает проблемы в системе государственного управления лесами, значительно снизилась доля лесного сектора в ВВП. В настоящее время на уровне Правительства РФ формируется новый Лесной кодекс РФ, совершенствуется Стратегия развития лесного комплекса РФ до 2030 года, разработаны новые финансово-экономические модели использования и воспроизводства лесных ресурсов и экосистемных услуг леса.

Abstract:
The current European Union’s and state agricultural support is more focused on the modernization of farms in technological terms, coupled with the intensification of production, and weakly focused on the farm exclusivity and diversification. This creates a minor motivation for farmers to address the issues related to climate change mitigation. The main attention in the article is concentrated on two themes: climate change and forest management. The main research methods were used: analysis and generalization of scientific literature, interview, logical and systematically reasoning, comparison, abstracts and other methods. The farms in the lower mountain ranges of Germany will change different climate conditions analyzed in the 2017 summer. Sustainable framing wide term in black forest, forest lands, organic farms, are depending or considering the climate cycles. In economic social conditions of Germany, black forest farming is so sensitive towards ancient methods of farming and their equations with the current environment. In simple terms, black forest sustainable framing is farming ecological by promoting methods and practices that are economically viable. It does not only particular about economic aspects of farming perhaps on the use of non-renewable factors in the process of thoughtful and effective farming. Agriculture land of Black Forest contributes to the nutrient and healthy food to reach high standard of living of the black forest society.

Abstract:
The agricultural operations in India are suffering from a serious problem of shortage of electrical power on one side and economic and effective disposal of agriwaste stuff on the other. India being agriculture based country, 70% of its main income (share in GDP) comes from agriculture sector. Any enhancement of income from this sector is based upon adequate supply of basic inputs in this sector. Regular and adequate power supply is one such input. But, the position of power supply in our country defies both these characteristics. With a major portion of power produced being sent to the industrial and urban consumers, there is a perennial shortage of power in the agriculture sector. Consequently, there is an emergent need to produce more power in order to fulfil the needs of this sector effectively. One way of accomplishing this is setting up captive, preferably rural based, small power generation plants. In these power plants, instead of water-head, diesel oil or coal, we can use agri-residue to produce electricity. One such power plant (1–2 MW capacity) can satisfy the power need of 25 to 40 nearby villages. The agriwaste like rice straw, sugarcane-trash, coir-pith, peanut shells, wheat stalks & straw, cottonseed, stalks and husk, soyabean stalks, maize stalks & cobs, sorghum. Bagasse, wallnut shells, sunflower seeds, shells, hulls and kernels and coconut husk, wastewood and saw dust can be fruitfully utilized in power generation. This stuff is otherwise a waste and liability and consumes a lot of effort on its disposal; in addition to being a fire and health hazard. Agriwaste stuff which at present is available in abundance and prospects of its utilization in producing energy are enormous. This material can be procured at reasonably low rates from the farmers who will thus be benefited economically, apart from being relieved of the responsibility of its disposal. Agri-residue has traditionally been a major source of heat energy in rural areas in India. It is a valuable fuel even in the sub-urban areas. Inspite of rapid increase in the supply of, access lo and use of fossil fuels, agri-residue is likely to continue to play an important role, in the foreseeable future. Therefore, developing and promoting techno-economically-viable technologies to utilize agri-residue efficiently should be a persuit of high priority. Though there is no authentic data available with regard to the exact quantity of agricultural and agro-industrial residues, its rough estimate has been put at about 350 mt per annum. It is also estimated that the total cattle refuse generated is nearly 250 mt per year. Further, nearly 20% of the total land is under forest cover, which produces approximately 50 mt of fuel wood and with associated forest waste of about 5 mt.(1). Taking into account the utilization of even a portion (say 30%) of this agri-residue & agro-industrial waste as well as energy plantation on one million hectare (mha) of wastelands for power generation through bioenergy technologies, a potential of some 18000 MW of power has been estimated. From the foregoing, it is clear that there is an enormous untapped potential for energy generation from agri-residue. What is required is an immediate and urgent intensification of dedicated efforts in this field, with a view to bringing down the unit energy cost and improving efficiency and reliability of agri-waste production, conversion and utilisation, leading to subsequent saving of fossil fuels for other pressing applications. The new initiatives in national energy policy are most urgently needed to accelerate the social and economic development of the rural areas. It demands a substantial increase in production and consumption of energy for productive purposes. Such initiatives are vital for promoting the goals of sustainability. cleaner production and reduction of long-term risks of environmental pollution and consequent adverse climatic changes in future. A much needed significant social, economic and industrial development has yet to take place in large parts of rural India; be it North, West, East or South. It can be well appreciated that a conscious management of agri-residue, which is otherwise a serious liability of the farmer, through its economic conversion into electric power can offer a reasonably viable solution to our developmental needs. This vision will have to be converted into a reality within a decade or so through dedicated and planned R&D work in this area. There is a shimmering promise that the whole process of harvesting, collection, transport and economic processing and utilisation of agri-waste can be made technically and economically more viable in future. Thus, the foregoing paras amply highlight the value of agri-residue as a prospective source of electric power, particularly for supplementing the main grid during the lean supply periods or peak load hours and also for serving the remote areas in the form of stand-alone units giving a boost to decentralised power supply. This approach and option seems to be positive in view of its potential contribution to our economic and social development. No doubt, this initiative needs to be backed and perused rigorously for removing regional imbalances as well as strengthening National economy. This paper reviews the current situation with regards to generation of agriwaste and its prospects of economic conversion into electrical power, technologies presently available for this purpose, and the problems faced in such efforts. It emphasizes the need for an integrated approach to devise ways and means for generating electrical power from agriwaste; keeping in mind the requirements of cleaner production and environmental protection so that the initiative leads to a total solution.

Abstract:
Abstract Recent interest in reducing stress on the food-energy-water (FEW) nexus requires the use of renewable, organic products that can subsequently address environmental sustainability concerns, such as mitigating greenhouse gas emissions. Pyrolysis-derived biochar from organic wastes (e.g., nutrient-rich agricultural wastes and leftovers, forest harvest residues, and cattle manure) and advanced feedstocks (e.g., algae) is capable of addressing ever-increasing global FEW concerns. Biochar water-nutrient holding capacity and carbon sequestration are key attributes for improving organic farming and irrigation management. The major challenge to commercialize biochar production from organic wastes is the conversion process. Pyrolysis process is a cost-effective and successful approach in comparison to other conversion technologies (e.g., gasification) due to low energy requirement and capital cost, as well as high process efficiency and biochar quality. To determine the environmental impacts of the biochar production process, an analysis of the material, energy, and emission flows of a small-scale pyrolysis process is conducted for a real case study, using life cycle assessment method with the assistance of available life cycle inventory databases within OpenLCA software. The results demonstrate that this study is able to enhance sustainability aspects across FEW systems by (a) employing a portable refinery to address upstream challenges (i.e., collection, transportation, and preprocessing) of waste-to-biochar life cycle, (b) recycling domestic forest and agricultural residues (e.g., pine wood), (c) producing organic biochar-derived soil conditioners that can improve organic cropping and FEW systems. Ultimately, we conclude by discussing techno-economic and socio-environmental implications of biochar production from organic wastes and advanced feedstocks.

Abstract:
Tree species are characterized by their perennial growth habit, woody morphology, long juvenile period phase, mostly outcrossing behaviour, highly heterozygosity genetic makeup, and relatively high genetic diversity. The economically important trees have been an integral part of the human life system due to their provision of timber, fruit, fodder, and medicinal and/or health benefits. Despite its widespread application in agriculture, industrial and medicinal values, the molecular aspects of key economic traits of many tree species remain largely unexplored. Over the past two decades, research on forest tree genomics has generally lagged behind that of other agronomic crops. Genomic research on trees is motivated by the need to support genetic improvement programmes mostly for food trees and timber, and develop diagnostic tools to assist in recommendation for optimum conservation, restoration and management of natural populations. Research on long-lived woody perennials is extending our molecular knowledge and understanding of complex life histories and adaptations to the environment, enriching a field that has traditionally drawn its biological inference from a few short-lived herbaceous species. These concerns have fostered research aimed at deciphering the genomic basis of complex traits that are related to the adaptive value of trees. This review summarizes the highlights of tree genomics and offers some priorities for accelerating progress in the next decade.
