Full textAbstract:
Achieving biologically diverse agricultural systems requires a commitment to changes in land use. While in-field agrobiodiversity is a critical route to such a transition, riparian systems remain an important, yet understudied, pathway to achieve key diversity and ecosystem services and targets. Notably, at the interface of agricultural landscapes and aquatic systems, the diversification of riparian buffers with trees reduces the non-point source pollution in waterways. However, in riparian agroforestry systems, little is known about herbaceous community patterns and, importantly, the herbaceous community’s role in governing carbon (C) and nitrogen (N) cycling. Our study investigated herbaceous community taxonomic and phylogenetic diversity patterns in riparian (i) grasslands (GRASSLAND), (ii) rehabilitated agroforests (AGROFOREST-REHAB), and (iii) remnant forests (AGROFOREST-NATURAL). We then determined the biodiversity-ecosystem function relationships between community functional diversity metrics, C and N cycling, and greenhouse gas fluxes. We observed significant differences in taxonomic and phylogenetic diversity among riparian buffer types. We found that herbaceous plant communities in riparian agroforestry systems expressed plant trait syndromes associated with fast-growing, resource acquiring strategies, while grassland buffer plants exhibited slow-growing, resource conserving strategies. Herbaceous communities with high functional diversity and resource acquiring trait syndromes, such as those in the agroforestry riparian systems, were significantly correlated with lower rates of soil CO2 efflux and N mineralization, both of which are key fluxes related to ecosystem service delivery. Our findings provide further evidence that functionally diverse, and not necessarily taxonomically diverse, plant communities are strongly correlated to positive ecosystem processes in riparian agroforestry systems, and that these communities contribute to the transition of agricultural lands toward biologically and functionally diverse landscapes.

Agroforestry is a land management system developed in the Bina Wana Community of Forest (HKm). Agroforestri in Community forest land is the main source of livelihood for communities around the forest. Labor is a resource that can affect the quality and quantity of forest product production, so it needs to be managed well in supporting agroforestry management in HKm. The purpose of this study was to analyze the distribution and contribution of outpoured labor in the family for each agroforestry activity in Gapoktan HKm Bina Wana. The data collection method was conducted by survey using interviews using questionnaires to 24 Gapoktan members. Data analysis was carried out by tabulation for all purposes in this study. The results showed that the distribution of labor outflows was most abundant in harvesting and postharvesting activities, namely 23% of the total use of labor for all agroforestry management activities. Subsequent sequences were soil cultivation (19.09%), planting (14.33%), fertilizing (13.26%), weeding (18.77%), and spraying (10.56%). Total of use of labor is 68% which is included in workers outside of the family. The contribution labor in the family towards agroforestry management in HKm Bina Wana shows a percentage of 32% of total workforce used.

This research aims to develop the model of land utilization in private forest management in order to support the food sustain in agroforestry system. The result shows that the clustering private forest for crops can predict the crops development area in private forest and management of agroforestry system performance in private forest. This model is related to knowledge management dan crops zoning. The private forest zoning can be classified into 2 main components : (i) planting area (ii) type of plants cultivated by the farmers. The forest management consists of horticulture plants stands, labor. It can be concluded that clustering model of agroforestry area utilization in supporting food sustain which is managed by laction question zoning principles can predict the domination of crops in private forest area. The crops which still become the mainstay of society, cassava value LQ 3.53 is still cultivated in 2015. In addition, for stands, mangga value 3.58 is still potential as an alternative choice in order to add income of society around the forest area in 2015.

Full textAbstract:
Integrated forestry-farming (agroforestry) management typically involves the planting of trees at a wide spacing with intercrops grown in alleys between trees. A program initiated in Missouri, USA in 1965 establishes eastern black walnut on a 40- × 10-foot spacing with row intercrops (wheat, milo, soybeans etc.) for the first 10-to-12 years followed by cover crops of cool-season forages thereafter. Specialty crops of Christmas trees, balled and burlapped landscaping species, small berry crops and vegetables are also grown during the early years of plantation establishment. Contrary to conventional management of black walnut, short, clear boles (8 to 16 feet in length) with large full crowns for nut production are developed for maximization of profits. Economic analyses show the highest investment returns associated with management practices combining nut and wood production within an agroforestry regime. Key words: Forestry-farming, agroforestry, eastern black walnut, economics

Full textAbstract:
Afforestation programs are challenged by competition for land uses. Land use conflicts arise whenever there is divergent use, access and management of the resource or due to incompatible use and inadequate policy. Agroforestry may reconcile competing interests. However, small landholdings remain a challenge due to the negative ecological and economic impacts of most economically preferred trees for agroforestry systems. Such negative impacts lead to the emergence of conflict among different land users and in most instances, slows down afforestation efforts on the farm. This study intended to explore conflicts arising from on-farm tree-planting and other land use practices, to identify the conflict resolution mechanism adopted by land users and to evaluate their strengths and weaknesses in conflict management. Mixed method approach of structured and semi-structured interviews was employed in Bobasi, Kisii County, Kenya. Content analysis, means, frequencies and cross-tabulations were done. Results indicated that small landholdings coupled with poor agroforestry practices were the main source of conflict driven by the ready market for trees of high economic values but with negative ecological impact. Conflict management mechanisms adopted were mainly cooperative methods such as voluntary negotiations between tree farmers and crop owners. These included adopting silvicultural control measures, benefit sharing of tree stems along the boundaries and compensation mechanisms for losses incurred by crop owners. Right based management mechanisms were also noted among other land users who believed that what they did with their land and compound was their business and so exhibited competitive approaches such as avoidance, coercion, and adjudication.

Full textAbstract:
Emergy analysis is used to evaluate agricultural management systems in order to diagnose their efficiency in using economic and natural resources. In this study, emergy analysis was used to evaluate an agroforestry production model and compare it to the traditional production model used in the semi-arid region of the northeast of Brazil. The agroforestry model comprises three subsystems: agrosilvopastoral (ASP), silvopastoral (SP) and preserved caatinga (CAT). For the traditional model, three subsystems were evaluated: an area under cultivation (AC); an area lying fallow for six years (F6); and an area fallow for nine years (F9). For each model and its respective subsystems, all input and output energy flows were identified. These flows were later quantified and transformed into emergy using their respective transformity values. The emergy performance of the systems and subsystems was evaluated by the indices: transformity (Tr), emergy investment ratio (EIR), emergy yield ratio (EYR), emergy renewability index (%R), environmental load rate (ELR), and emergy sustainability index (ESI). It was found that the agroforestry model uses a lower quantity (-13%) of natural resources than the traditional model. However, the agroforestry model uses 64% more resources from the economy than used in AC. More than 55% of the emergy required in the ASP and AC subsystems comes from services. The subsystems that required a greater amount of emergy and achieved less efficiency were SP in the agroforestry model and AG in the traditional model. Values for Tr were lower in CAT (2.6E+03) and higher in AC (2.4E+05). The ELR was low in all areas, ranging from 0.00 in F6 and F9 to 0.58 in SP. Values for %R ranged from 60.76 in AC to 99.98 in F6. The agroforestry system displayed better emergy performance due to a lower values for Tr and ELR, and greater renewability.

Full textAbstract:
Land degradation is major challenge of Nepal. The paper focuses mainly on causes and consequences of land degradation and their management approaches. Land degradation may occur through different physical, chemical and biological processes induced directly or indirectly by human activities like deforestation, shifting cultivation, overgrazing, steep slope farming, over use of chemical fertilizers and forest resources. These create many social problems like poverty, poor health and nutrition and demographic dynamics by lowering agricultural productivity. Agroforestry approaches like use of Multi Purpose Tree Species (MPTs), relay-cropping, terracing and contour cultivation, strip and alley cropping are appropriate to fulfill the needs of low resource farmers by restoring and increasing land productivity. The potentiality of the approach can be made more effective through holistic efforts, based on needs with active participation of farmers in planning and implementation stage.

Full textAbstract:
The change in land use as well as elevation changes microbial biomass carbon (C), nitrogen (N) and water extractable organic carbons (WOC), which are important parameters of soil fertility and essential for sustainable management of any land use. In Central Himalaya watershed (2B4D6) the land use pattern varies with elevation. The present study aims to examine the soils (0-30 cm depth) of different land uses i.e. agroforestry, silvipastoral and grassland for microbial biomass C, N, microbial population and WOC along the elevation. Microbial biomass C, N, microbial population and WOC contents varied significantly (less than 0.005) among land uses and it increased along the elevation. Maximum microbial biomass C and N was recorded in agroforestry, silvipastoral and minimum in grassland. While, WOC highest in silvipasture, agroforestry and grassland. Land uses along elevation had strong positive correlation with microbial biomass C, N and WOC. Thus it is concluded that microbial biomass C, N, microbial population and WOC changes significantly (less than 0.05) in different land uses and along elevation gradient.

Land use and management systems are factors that can influence carbon stock and its aggregate stability. This study assessed the carbon stock and aggregate stability of Inceptisols under different land use and management systems. The study was conducted on five properties located in the southern region of Amazonas state. Five areas were selected with different traditional land use systems (agroforestry, cassava, sugarcane, pasture and native forest). On each site, grids of 50 m x 50 m, with regular spacing of 10 by 10 meters were outlined for a sampling of 36 points in each mesh at a depth 0.00-0.10 m. We determined the bulk density, aggregate stability, total organic carbon and carbon stock. Data were subjected to analysis of variance (F test) and means were compared by Tukey test at 5% probability. We found that the highest values of carbon stocks were found in areas under sugar cane and pasture, followed by the areas under cassava, agroforestry and native forest. Carbon stocks and aggregate stability were significantly altered by land use management systems.

Full textAbstract:
Almost 20 million non-forest, cropland acres in the south-eastern United States can be classified as marginal. Demand projections for forest products call for a 40% increase by year 2030. Recently more land is being logged than regenerated. Land multiple use management, combining trees, cattle and wildlife, adjusts cash flows forward mitigating negative cash flow period associated with conventional forest production. Profit opportunities for smaller landowners are increased. Modification of tree population and spacing, allowing inclusion of hay and pasture, increases net present value (NPV) of agroforestry over traditional forestry. Model results show an increase in NPV from $554 to $948 per acre when beef cattle are added to loblolly pines on marginal lands. Key words: agroforestry, pines, cattle, NPV, multiple use

ABSTRACT: The evaluation of land use and management by the measurement of soil organic matter and its fractions has gained attention since it helps in the understanding of the dynamics of their contribution to soil productivity, especially in tropical environments. This study was conducted in the municipality of Colorado do Oeste, state of Rondônia, Brazil and its aim was to determinethe quantity of organic carbon and total nitrogen in the light and heavy fractions of organic matter in the surface layers of a typic hapludalf under different land use systems: Native Forest: open evergreen forest, reference environment; Agroforestry System 1: teak (Tectona grandis LF) and kudzu (Pueraria montana); Agroforestry System 2: coffee (Coffea canephora), marandu palisade grass (Brachiaria brizantha cv. Marandu), "pinho cuiabano" (Parkia multijuga), teak and kudzu.; Agroforestry System 3: teak and cocoa (Theobroma cacao); Silvopasture System: teak, cocoa and marandu palisade grass; and Extensive Grazing System: marandu palisade grass. The experimental design was a randomized block in split-split plots (use systems versus soil layers of 0-0.05 and 0.05-0.10 m) with three replications. The results showed that relative to Native Forest, the Agroforestry System 2 had equal- and greater amounts of organic carbon and total nitrogen respectively (light and heavy fractions) in the soil organic matter, with the light fraction being responsible for storage of approximately 45% and 70% of the organic carbon and total nitrogen, respectively. Therefore, the light densimetric fraction proved to be useful in the early identification of the general decline of the soil organic matter in the land use systems evaluated.

Community Forest (HKm) is one of the schemes of Social Forestry, in which the management of its working area implements the agroforestry system. This study aims to determine the structure of income and farmer welfare, agroforestry contribution to farmer income and the factors that influence the income of farmers who do agroforestry in HKm working area. The study was conducted at the Group of HKm Bina Wana, Rigis Jaya II and Mitra Wana Lestari Sejahtera, West Lampung District. The results show that agroforestry activities contribute to farmer income of 66% and the rest from other sectors. Based on income from agroforestry activities it is known that 93% of farmers are in the prosperous category. Factors that significantly affect farmers' income are the area of cultivated land, the number of plant species that have been produced and the training followed by the farmers. In accordance with the provisions of the farmers' land area within the HKm area is no longer possible to be expanded, therefore farmers should enrich with more types of multi-use plants and follow training to increase knowledge so that land management is more optimal to increase revenue.

The objective sought by this study is to highlight the socio-economic determinants that could be helpful in scaling up of best land management practices in high demographics areas. Indeed, a survey was carried out in Dan Saga and Tabofatt two villages’ clusters in order to identify the driver factors which explain the high adoption of best land management practices in these areas. The data were collected from 200 farmers (100 from each cluster), randomly chosen. The survey addressed the likelihood of farmer to use agroforestry practices and or erosion control practices, on the basis of four socioeconomics variables: the educational level of farmer (Instr), the distance between their farm and habitation (Prox), the possession of Harnessed Cultivation Unit (HCU) and the land tenure status (Land). Data were subjected to an analysis by statistical modeling of logistic regression. The results show that agroforestry technology is predominated in Dan Saga cluster (90% of citation for agroforestry practices) compare to Tabofatt cluster where people use mostly erosion control practices (76% of citation for erosion control practices). Among the socioeconomics variables, three main factors significantly influenced the adoption of best land management; the educational level of peasants, the modality of land tenure by purchase and by inheritance and the possession of harness unit. In addition, the main land management technologies perform a high profitability compare to state of inaction. These results could serve as a lever for scaling up of regreening policy in other degraded areas of Sahel’s region.

Full textAbstract:
Location-specific forms of agroforestry management can reduce problems in the forest–water–people nexus, by balancing upstream and downstream interests, but social and ecological finetuning is needed. New ways of achieving shared understanding of the underlying ecological and social-ecological relations is needed to adapt and contextualize generic solutions. Addressing these challenges between thirteen cases of tropical agroforestry scenario development across three continents requires exploration of generic aspects of issues, knowledge and participative approaches. Participative projects with local stakeholders increasingly use ‘serious gaming’. Although helpful, serious games so far (1) appear to be ad hoc, case dependent, with poorly defined extrapolation domains, (2) require heavy research investment, (3) have untested cultural limitations and (4) lack clarity on where and how they can be used in policy making. We classify the main forest–water–people nexus issues and the types of land-use solutions that shape local discourses and that are to be brought to life in the games. Four ‘prototype’ games will be further used to test hypotheses about the four problems identified constraining game use. The resulting generic forest–water–people games will be the outcome of the project “Scenario evaluation for sustainable agroforestry management through forest-water-people games” (SESAM), for which this article provides a preview.

The area of degreded peatlands in Indonesia is estimated at 4.4 million ha. Currently, the degraded peatland often a source of environmental problems, including sources of greenhouse gas (GHG) emissions and land fires. Restoration of degraded peatlands is intended to restore the value, function and benefits of the peat ecosystem, including efforts to prevent land damage, provide protection, and restore the ecosystem. One of the efforts to restore degraded peatlands is through revegetation. Agroforestry is a cropping pattern that uses a combination of tree crops with seasonal crops, and/or with livestock/fisheries activities. Agroforestry systems can be applied to degraded peatlands in production forest areas and other use areas. The advantages of agroforestry systems include; optimization of land, diversification of crops, reduce the risk of failure, can also prevent land preparation (for seasonal crops) with the burn system, and increase carbon stock. The success of an agroforestry system is very dependent on tree management which can reduce adverse effects and maximize the beneficial effects physically, economically, socially and environmentally. The selection of tree and agricultural plant types is important in order to restore degraded peatlands. The jelutung + pineapple agroforestry system provides physical, economic, social and environmental benefits. Jelutung + corn + horticultural crops are able to provide significant benefits. Agroforestry systems can be implemented to mitigate carbon emissions in degraded peatlands.

Identifying the importance of soil biology in different land use systems is critical to assess the present conditions of declining soil (C) and global land degradation while regulating soil health and biogeochemical nutrient cycling. A study was undertaken in a mixed watershed comprising of different land use systems (agricultural, grassland, agroforestry, and eroded); situated in the Shiwalik region in the foot hills of the lower Himalayas in India, a fragile ecosystem susceptible to land degradation. Soil samples from 0–15 and 15–30 cm depths were collected from these land use systems and analyzed for a suite of different soil health indicators, including physio-chemical soil properties, aggregate stability, soil microflora, and the enzymatic activities that are critical for nutrient cycling. Principal component analysis was used to group different land uses and understand their association with soil microflora, enzyme activities, and soil physio-chemical properties. We found that a greater number of soil microflora and enzymatic activities were associated with grassland and agroforestry land use systems. Aggregate-associated soil C correlated well with the soil microflora under different land use systems studied. The biplots revealed that the fungal:bacterial ratio (2 × 103–0.1 × 103) was a robust indicator of C accumulation and soil health, and was in greater association with the agroforestry land use system. Random forest, a non-parametric statistical test, on average explained that 68% to 92% of the variability in soil microbial population was due to land use and other soil health properties. Overall, the biological soil health indicators used in this study demonstrated the fact that land use management systems that employ constant crop cover with minimal disturbance have the potential to improve soil sustainability and ecological functioning.

Full textAbstract:
Cocoa agroforestry has evolved into an accepted natural resource conservation strategy in the tropics. It is regularly proposed as one of the main uses for REDD+ projects (Reducing Emissions from Deforestation and forest Degradation and the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks in developing countries) in the Democratic Republic of the Congo. However, few studies have characterized the cocoa agroforestry systems in this country. Hence, this research proposes to determine the impact of distance from Kisangani (the unique city in the landscape) and land-use intensity on the floristic composition of cocoa agroforests in Bengamisa-Yangambi forest landscape in the Congo Basin. The results revealed that species diversity and density of plants associated with cocoa are influenced by the distance from Kisangani (the main city in the landscape and province). Farmers maintain/introduce trees that play one or more of several roles. They may host caterpillars, provide food, medicine, or timber, or deliver other functions such as providing shade to the cocoa tree. Farmers maintain plants with edible products (mainly oil palms) in their agroforests more than other plants. Thus, these agroforests play key roles in conserving the floristic diversity of degraded areas. As cocoa agroforestry has greater potential for production, biodiversity conservation, and environmental protection, it should be used to slow down or even stop deforestation and forest degradation.

Full textAbstract:
Agroforestry systems have been promoted as a solution to address trade-offs between environmental conservation efforts and the need for increased agricultural productivity on smallholder farms in Brazil. However, the impact of land use change from degraded pasture to agroforestry on soil properties remains unclear. The objectives of this research were to: (1) assess soil chemical, physical and biological properties across distinct land uses (degraded pasture, agroforestry and secondary forest); and (2) understand relationships between litter quality, soil organic matter (SOM) and key soil quality parameters in the Brazilian Atlantic Rainforest. Soils, macroinvertebrates and litter were collected in April and September of 2018 under five land uses, including: three types of agroforestry systems, a degraded pasture and a secondary forest in Sapucaia, Rio de Janeiro, Brazil. Our results showed that soil properties clearly separated the three agroforestry systems plots (AS1, AS2, AS3) from the forest and pasture plots. Moreover, litter quality and SOM likely influence multiple biological and physiochemical soil properties under agroforestry systems and secondary forest. Our findings suggest that agroforestry systems can help support soil biological, chemical and physical properties and that the litter quality may be an important driver of their effects and potential contributions to soil restoration in the region.

Land-use change forest conversion and poor land management have damaged forest ecosystem. It is automatically disturbing the components in the forest ecosystem, among other soil arthropods. Therefore, environmental friendly land management system is required. One such system is Sengon-based Agroforestry with Porang Cultivation. The objective of research is (1) to understand the structure and function of soil arthropods in the Porang and non-Porang lands; Research is conducted at KPH Saradan, Madiun Regency. Two locations are chosen, Agroforestry land with Porang cultivation and non-Porang Agroforestry land. Method of research is observational survey. Sampling technique toward Arthropod is Pitfall Trap. Result of research indicates that the diversity of soil Arthropods family in the Porang land is counted to 27 families, while in the non-Porang land, 30 families of soil Arthropods are estimated. Shannon-Wienner Diversity Index in the non-Porang land is in low category with H>1 (1.32), while the diversity index in the Porang land is in very low category with H<1 (0.83). Bray-Curtis Index, which is measuring the similarity of two compositions of land community in the Porang and non-Porang lands, is counted to 0.91, submitting to the category of not different. The community of land Arthropods in the Porang land plays some roles such as soil decomposer (57 %), litter transformer (22%), and predator (21%). The roles of litter transformer and predator have similar rate (26 %).

"Mountain Farming Systems’ Exposure and Sensitivity to Climate Change and Variability: Agroforestry and Conventional Agriculture Systems Compared in Ecuador’s Indigenous Territory of Kayambi People."

Full textAbstract:
Smallholder farming is considered one of the most vulnerable sectors to the impacts of climate change, variability, and extremes, especially in the developing world. This high vulnerability is due to the socioeconomic limitations and high environmental sensitivity which affect the biophysical and socioeconomic components of their farming systems. Therefore, systems’ functionality and farmers’ livelihoods will also be affected, with significant implications for global food security, land-use/land-cover change processes and agrobiodiversity conservation. Thus, less vulnerable and more resilient smallholder farming systems constitute an important requisite for sustainable land management and to safeguard the livelihoods of millions of rural and urban households. This study compares a comprehensive socioeconomic and environmental dataset collected in 2015–2016 based on household interviews of 30 farmers of highland agroforestry systems and 30 farmers of conventional agriculture systems, to determine which system provides better opportunities to reduce exposure and sensitivity. A modified Climate Change Questionnaire Version 2 of the World Overview of Conservation Approaches and Technologies (WOCAT) was applied to collect the data. The interview data are based on the perceptions of Kayambi indigenous farmers about the levels of exposure and sensitivity of their farming systems during the last decade. Descriptive statistics were applied to analyze the data from the 60 farms. Results indicate that both agroforesters and conventional farmers clearly perceived increases in temperature and reductions in precipitation for the last decade, and expected this trend to continue in the next decade. Furthermore, conventional farmers perceived greater exposure to droughts (20%), solar radiation (43%), and pests, weeds and disease outbreaks (40%) than agroforesters. Additionally, results emphasize the better ability of agroforestry systems to reduce exposure and sensitivity to climate change and variability. These findings support the well-known assumptions about the key role played by agroforestry systems for climate change adaptation and mitigation, especially in developing countries.

Full textAbstract:
Arbuscular mycorrhizal fungi (AMF) are important components of the soil microbiota in terrestrial ecosystems, under the influence of various factors such as soil use and management, and can be adapted to a structure and diversity of fungal communities. The aim of this survey was to evaluate the influence of different systems of land use and management on AMF diversity in the Roraima State, Brazil. We collected soil samples in agroforestry, conventional soybean planting, conventional corn and native forest. After 150 days of incubation in a greenhouse, we extracted the spores in order to evaluate AMF, volume and to determine taxonomic identification. We found 16 species of AMF and the genus Acaulospora was the most frequent, followed by Glomus. Soil under agroforestry system had the highest species richness and the native forest, the lowest. On the other hand, soybean and corn areas presented greater density values than agroforestry system and native forest. In the agroforestry system, SOM attributes, Al3+ and H + Al had influence in AMF species richness. Thus, agroforestry constitute sustainable alternative influencing AMF communities in these ecosystems.

This study evaluated the contribution of agroforestry (AFS) and traditional systems to carbon sequestration and nutrient reserves in plants, litter and soil. The study was carried out in the semiarid region of Brazil in a long-term experiment on an experimental farm of the goat and sheep section of the Brazilian Agricultural Research Corporation (Embrapa). Two agroforestry systems were investigated: agrosilvopastoral (ASP) and forest-pasture areas (SP) as well as traditional agriculture management (TM), two areas left fallow after TM (six fallow years - F6 and nine fallow years - F9) and one area of preserved Caatinga vegetation (CAT). Soil, litter and plants were sampled from all areas and the contents of C, N, P, K, Ca and Mg per compartment determined. The AFS (ASP and SP) had higher nutrient stocks than the traditional and intermediate stocks compared to the preserved Caatinga. In the ASP, a relevant part of the nutrients extracted by crops is returned to the system by constant inputs of litter, weeding of herbaceous vegetation and cutting of the legume crops. After fallow periods of six and nine years, carbon and nutrient stocks in the compartments soil, litter and herbaceous plants were similar to those of the preserved Caatinga (CAT), but still lower than under natural conditions in the woody vegetation.

Agroforestry systems are part of the history of the European Union rural landscapes, but the regional increase of size of agricultural parcels had a significant effect on European land use in the 20th century, thereby it has radically reduced the coverage of natural forest. However, this cause conflicts between interest of agricultural and forestry sectors. The agroforestry land uses could be a solution of this conflict management. One real – ecological – problem with the remnant forests and new forest plantation is the partly missing of network function without connecting ecological green corridors, the other problem is verifiability for the agroforestry payment system, monitoring the arable lands and plantations.
Remote sensing methods are currently used to supervise European Union payments. Nowadays, next to use satellite imagery the airborne hyperspectral and LiDAR (Light Detection And Ranging) remote sensing technologies are becoming more widespread use for nature, environmental, forest, agriculture protection, conservation and monitoring and it is an effective tool for monitoring biomass production.
In this Hungarian case study we made a Spatial Decision Support System (SDSS) to create agroforestry site selection model. The aim of model building was to ensure the continuity of ecological green corridors, maintain the appropriate land use of regional endowments. The investigation tool was the more widely used hyperspectral and airborne LiDAR remote sensing technologies which can provide appropriate data acquisition and data processing tools to build a decision support system.

Incongruous management techniques have been associated with some significant loss of agricultural land to degradation in many parts of the world. Land degradation results in the alteration of physical, chemical and biological properties of the soil, thereby posing a serious threat to sustainable agricultural development. In this study, our objective is to evaluate the changes in a Cambisol structure under six land use systems using the load bearing capacity model. Sampling was conducted in Amazonas Region, Brazil, in the following land use: a) young secondary forest; b) old secondary forest; c) forest; d) pasture; e) cropping, and f) agroforestry. To obtain the load bearing capacity models the undisturbed soil samples were collected in those land use systems and subjected to the uniaxial compression test. These models were used to evaluate which land use system preserved or degraded the Cambisol structure. The results of the bulk density and total porosity of the soil samples were not adequate to quantify structural degradation in Cambisol. Using the forest topsoil level (0-0.03 m) as a reference, it was observed that pasture land use system was most severe in the degradation of the soil structure while the structure were most preserved under old secondary forest, cropping system and forest. At the subsoil level (0.10-0.13 m depth), the soil structure was most degraded in the cropping land use system while it was most preserved in young secondary forest and pasture. At the 0.20-0.23 m depth, soil structure degradation was most severe in the old secondary forest system and well preserved in young secondary forest, cropping and agroforestry.

Full textAbstract:
SUMMARYAlthough small-scale agroforestry systems (swiddens, complex and single-crop-dominated agroforests, and homegardens) form a diverse and important tropical land use, there has been no attempt to collate information on their value for biodiversity. This paper reviews 52 published studies that compared species richness and/or abundance between agroforests and primary forest, and 27 studies that compared biodiversity parameters across agroforests. The former covered a broad range of taxa and geographical areas, but few focused on homegardens, while those comparing across agroforestry systems were biased towards studies of plants (21 studies) and homegardens (13 of 27). Of 43 studies comparing species richness or diversity across habitats, 34 reported lower richness in agroforests than in adjacent forest. There was also high β diversity between primary forests and agroforests. Patterns of abundance shifts were less straightforward, with many species traits (for example diets) being generally poor indicators of response to agricultural disturbance. Among the few trends identified, restricted-range or rare species, and terrestrial and some understorey vertebrates tended to decline most, and open country species, granivores and generalists increased most in agroforests. Variability in biodiversity retention across systems has been linked most strongly to economic function, management intensity and extent of remnant forest within the landscape, as well as more subtle cultural influences. Species richness and abundance generally decrease with increasing prevalence of crop species, more intensive management, decreasing stratum richness and shortening of cultivation cycles. Increasing holding size did not necessarily reduce α diversity. Knowledge of the general effects of small-scale agroforestry on biodiversity is substantial, but the great diversity of systems and species responses mean that it is difficult to accurately predict biodiversity losses and gains at a local level. Further work is required on the influence of spatial and temporal structure of agricultural holdings on biodiversity retention across agriculture/succession/forest mosaics, how β diversity across individual holdings influences biodiversity across landscapes, and ultimately on how agricultural intensification can be best managed to minimize future losses of biodiversity from tropical landscapes.

Most of the agroforestry systems (AFS) in Nepal are traditional, and deliberate management of trees, crops and livestock as an integrated and interactive agroecosystem, albeit its enormous socio-economic and ecological benefits, is limited. The objective of this review paper is to understand the prospects, analyze challenges and suggest practical solution for promoting agroforestry as a viable system balancing economic, social and environmental concerns. We develop this paper based on practical experience on the ground and an in-depth review of relevant literature and highlights the prospects, challenges and ways forward of AFS, both farm-based and forest-based, in Nepal. Nepal has enormous agroecological diversity, suitable land availability for agroforestry, traditional knowledge, skill and labor forces, and huge prospects of adapting new technologies and developing market systems, especially considering emerging markets for developing remunerative and environment friendly value chains. However, the prospective value chains of the mountain agroforestry products face many challenges, including i) socio-economic constraints of the farmers mainly because of high initial adoption costs, limited information on benefit-cost of agroforestry practices, limited knowledge on full benefits of agroforestry, and limited markets and marketing information; ii) institutional constraints because of unclear policy to support agroforestry, the lack of extension services and undefined administrative boundaries; and iii) inadequate scientific knowledge, expertise and technologies to address management complexity of agroforestry system. We therefore suggest having a scan of those challenges and find out solutions, especially for promoting growth and competitiveness of the sector with poverty reduction strategy ensuring availability of food, fuel, fodder and employment opportunity for local communities. The paper provides a few successful cases of AFS and finally suggests ways forward to promote AFS and a business model which could help achieve the untapped potentials for enhancing income and employment opportunity, achieving food and nutrition security, and building sustainable land use systems.

Full textAbstract:
Agroforestry, the intentional integration of trees with crops and/or livestock, can lead to multiple economic and ecological benefits compared to trees and crops/livestock grown separately. Field experimentation has been the primary approach to understanding the tree–crop interactions inherent in agroforestry. However, the number of field experiments has been limited by slow tree maturation and difficulty in obtaining consistent funding. Models have the potential to overcome these hurdles and rapidly advance understanding of agroforestry systems. Hi-sAFe is a mechanistic, biophysical model designed to explore the interactions within agroforestry systems that mix trees with crops. The model couples the pre-existing STICS crop model to a new tree model that includes several plasticity mechanisms responsive to tree–tree and tree–crop competition for light, water, and nitrogen. Monoculture crop and tree systems can also be simulated, enabling calculation of the land equivalent ratio. The model’s 3D and spatially explicit form is key for accurately representing many competition and facilitation processes. Hi-sAFe is a novel tool for exploring agroforestry designs (e.g., tree spacing, crop type, tree row orientation), management strategies (e.g., thinning, branch pruning, root pruning, fertilization, irrigation), and responses to environmental variation (e.g., latitude, climate change, soil depth, soil structure and fertility, fluctuating water table). By improving our understanding of the complex interactions within agroforestry systems, Hi-sAFe can ultimately facilitate adoption of agroforestry as a sustainable land-use practice.

In Colombia, one-third of the land is devoted to cattle farming, which is one of the main drivers of deforestation, land degradation, loss of biodiversity, and emissions of greenhouses gases. To mitigate the environmental impacts of cattle farming, agroforestry practices have been extensively promoted with mixed results. Despite research and extension efforts over the last 20-year period, agroforestry systems still involve a complex knowledge process among stakeholders that needs to be addressed. To understand the drivers of cattle farmers’ behavior with regard to adopting agroforestry practices, we apply a double hurdle regression for different social, economic and productive information to capture the decision to adopt and the intensity of the adoption as a joint decision of such practices. For this purpose, we use data from a survey (implemented as part of an international project) administered to 1605 cattle farmers located in five agro-ecological regions in Colombia. Our dependent variables are defined by the adoption of four agroforestry practices: scattered trees, trees and shrubs for forage production, forestry plantations, and management of native forest. The adoption decision of agroforestry practices was influenced by the access and use of credit, location, and the implemented livestock system. Herd size and participation in development projects that involved tree planting had a positive influence on the adoption and intensity of agroforestry practices, while the variable associated with presence of water springs tended to boost the intensity of adoption. The diffusion of these technologies might be increased among farmers who have adopted and who are potential adopters, and social capital and networking can play a crucial role in spreading agroforestry as sustainable practice.

There has been an incessant conversion of natural forests to agricultural land uses such as farmlands, grasslands and parkland agro-forestry in Africa during the last century. This study investigated changes in soil organic carbon (SOC) and total nitrogen (TN) stocks following the conversion of a natural forest to coffee-based agro-forestry, grazing grassland and well-managed maize farm in a sub-humid tropical climate of Ethiopia. Soil samples (up to 1m depth) were taken from each of these four land use types. Taking the natural forest as a baseline and with duration of 35 years since land use conversion, the total SOC and TN stocks were not significantly different (P > 0.05) among the different land use types when the entire 1m soil depth was considered. However, in the upper 0-10cm soil depth, the SOC and TN stocks were significantly higher (P < 0.05) in the natural forest than the agricultural land use types. There were different patterns of SOC and TN distributions along the soil depths for the different land use types. The SOC stocks decreased with depth in natural forest, but did not show any increasing or decreasing trends in maize farm, grazing grassland, and coffee-based agroforestry. The results of this study revealed that the negative effects of converting natural forests to agricultural land use types on SOC and TN can be prevented through appropriate land management practices in cultivated and grazing lands and use of proper agroforestry practices in a sub-humid tropical climate.

Agroforestry is a land use system that aims to sustain or increase total yields sustainably. Community Forest Utilization Permit (IUPHKm) is a business permit granted to local community groups to utilize forests in protected forest areas and / or production forest areas. HKm management for the community in the Melinani sub-district was carried out based on the technical design of agroforestry made by BPSKL in the Maluku and Papua regions. The research objectives are: (1) Knowing the economic, social and cultural and ecological characteristics of the Melinani community in utilizing Hkm; (2) Determine strategies and priorities for developing agroforestry systems and (3) Analyze the factors that determine the effectiveness of farmers' work. Multiple regression analysis is used in this research. For the determination of agroforestry development strategies used SWOT analysis and priority setting that must be carried out using the QSPM method. The results of the regression analysis indicate that the level of education and distance from residence have an impact on the development of agroforestry. The SWOT analysis is in the quadrant I. This means that even though the management of agroforestry development is under threat, it can be used to exploit opportunities. The results of QSPM calculations are 4 alternative agrofoestry management strategies in HKm. The technical design of agroforestry is still focused on agriculture and plantation crops, not yet combined with forestry plants, so the strata of the plant have not been well formed.

The unique Walnut Fruit Forests in Kyrgyzstan are a good example of the multifunctional use of forests in temperate zones. Not only are non-timber forest products (NTFPs) collected but the land in and around the forests is used for grazing and haymaking, as well as for arable cropping and the establishment of fruit orchards. Apart from sustaining the lives of the local mountain people, the Walnut Fruit Forests are extremely rich in biodiversity and have an important function as a watershed for the Ferghana valley. The simultaneous dependence of the population on both agriculture and forest offers ideal conditions for the extension and improvement of existing agroforestry systems. However, solutions must be found concerning the practice of uncontrolled grazing, the insecure land and tree tenure situation, the low productivity of the existing land use systems, the lack of agricultural advice and training and the serious impact of firewood collection on the forests in order to safeguard the Walnut Fruit Forest’s biodiversity while integrating the needs of the local population into forest management.

Kemuning sub village district is located in Bunder village, Patuk, Gunung Kidul. This area is near by the Bunder forest park and Wanagama Educational Forest. Most of the people live there are farmers. As the soil is relatively unfertile, they prefer to plant trees, so they called as forest community farmers. Among the trees, they plant cassava, peanut, and corn, so it called as agroforestry. In the field, the area seems still has the opportunity that can be added to be planted. Based on this situation, in this project, the optimalization of land use was introduced to ask the farmers to plant the undergrowth species includes: zingiber, kunyit and kencur. This project was started by introducing the agroforestry system, where they can plant together both trees and non trees at the same land. The socialization was done by inviting the farmers to come to the meeting. The advantages of agroforestry was explained to them, and also the post harvesting management to produce the instant zingiber was also trained and demonstrated to the female farmers. This product is also useful for attracting the local tourist who usually come at the week end. The output of this project was the agroforestry demplot can be built in the field, so the farmers can learn and study to develope at their own land. The female farmer can also make the instant zingiber as the healthy drink.

<p><strong>Abstract.</strong> Agroforestry is an integrated self-sustainable land use management system that is not only capable of producing food from marginal agricultural land but also capable of maintaining and improving the quality of environment. Accurate assessment of trees on farmlands i.e. agroforestry would help in determining their contribution in meeting timber demand and also in carbon sequestration vis-a-vis climate change mitigation. In the present, high resolution multispectral satellite imagery (LISS-IV) has been used for mapping and estimating agroforestry area in Koraput district of Odisha. Both supervised and Object based Image Analysis (OBIA) classifications methods have been applied. In case of supervised maximum likelihood method, those pixels are fully captured where trees exist, whereas in OBIA captures trees according to their crown shapes. This proved OBIA method to be better in identification of trees on farmlands (scattered trees, boundary, and block plantations) than supervised method. This can lead to accurate estimation of area under trees in scattered form, in linear form and also in patch form. Improved results were obtained in case of OBIA classification with more than 90% accuracy. This research implies that remote sensing provide promising tools for evaluating and mapping of agroforestry at district level. Hence, the proposed approach of using high resolution remote sensing data in conjunction with OBIA method would be promising for mapping agroforestry area.</p>

Full textAbstract:
Agroforestry is receiving a win-win strategy for low-income countries through increasing attention in Bangladesh especially in the coastal region because of its capacity to address some of the negative consequences of intensive agriculture with sustainable perceptions, attitudes, and management through farmers both locally and globally. As the actual uptake and maintenance of agroforestry in proximity to the coastal area by farmers remains low and that is why this research work investigates agroforestry practices e.g., Homestead agroforestry, boundary plantation, mixed plantation, cropland agroforestry, agrisilvicultural systems, Agro-aqua silviculture, and Agro-aquaculture systems on a sustainable basis with a view to find out the farmers ‘perceptions and attitudes through identifying their constraints and problems with potential opportunities to adopt agroforestry in Satkhira district of Bangladesh. A sample of 80 respondents selected randomly was interviewed through a semi-structured interview schedule individually and a multistage random sampling technique was adopted to conduct the study. Therefore, results revealed that middle-aged farmers (36-50) (46%) are interested in agroforestry practice than a traditional practice. The adoption of younger (26-35) 35% farmers is increasing day by day since they have had more schooling than the older generation or perhaps have been exposed to new ideas as a migrant. Illiteracy (56%) has primary level of education) is the main reason for non-adoption of agroforestry. The farmers (28%) they taken lease from other people who have no own land they are not interested in agroforestry. Farmers (47%) are interested in agro-aquaculture practice, because high cash return get from this practice. About 68.7% respondents have taken positively agroforestry practice, but they have no training skill or facility. If they get this facility, they are more interested in agroforestry practice. Finally result mentioned that 76.25% respondents perceived agroforestry positively and most of the farmer’s (68.7%) have positive attitude towards it whilst maximum farmers (80%) think agroforestry system should be expanded. This research indicates that agroforestry is a catalyst factor which can be adopted more through directed programs, policies and practices by government and its related agencies from this positive perceptions and attitudes of this research. Thus, agroforestry is a sustainable potential land use in the long term through combination of intrinsic and extrinsic factors interact and drive adoption can help integrating technologies appropriately to ensure sustainability adjacent to the coastal region of Sundarbans of Bangladesh.

Agroforestry is attracting considerable attention in Ethiopia because of its potential for sustainable land use practices. As land tenure insecurity is a major limiting factor for sustainable land use practices in Ethiopia and developing countries in general, the Ethiopian government launched a rural land certification program to secure land tenure. There are limited empirical studies about the impacts of land certification on sustainable land use practices. To fill this knowledge gap, this study was outlined for an area in the Ethiopian Gozamen district. It investigates the impact of land certification on sustainable land use practices and is focused on factors affecting tree plantation based on a household survey, key informant interviews, focus group discussions, and field observations. The results of the study showed that the majority of the respondents practiced sustainable land use practices after their land was certified. Therefore, land certification has a great contribution on sustainable land use practices. In addition, age, consultancy, land size, education, and nurseries proved as significant factors for tree plantation. As access to land is a basic socio-economic precondition for sustainable agriculture and forestry in developing countries, tenure security is a key pathway for the development of the poor and it contributes essentially to achieve sustainable development goals.

Full textAbstract:
The world is faced with dual challenges to ensure food security for its large and still growing population and to mitigate climate change. It is necessary to develop more diversified and multifunction agricultural systems to address the challenges. Therefore, as a reasonable land use practice, agroforestry has become the hotspot in scientific research in recent decades. This study performed quantitative and qualitative analyses of agroforestry research published between 1990 and 2018 based on bibliometric methods, expecting to guidance for further research in order to scientifically understand of the trends and features of agroforestry research over time and by region. A total of 4204 publications were obtained from Web of Science. The results show that the research interest in the agroforestry field has significantly enhanced, and about 139 countries have been involved with the research in this field. These publications cover 66 subject categories and a great diversity research theme. Since 1990, the popular keywords in agroforestry research have been changed from “Intercropping”, “Alley cropping”, and “Multipurpose trees” to “Carbon sequestration”, “Ecosystem service”, and “Climate change”. This indicates that the theme of agroforestry research has changed and the research scale is gradually expanding. Furthermore, agroforestry research themes vary with regions, since different regions have various requirements on the function of the agroforestry system. In the end, given the current trend of agroforestry science, we conclude a list of research potentials of agroforestry in the future.

Full textAbstract:
Secondary tropical forests and coffee agroforestry systems contain fewer trees than native forests but can positively impact soil hydrological functions, such as water infiltration compared to the pasture land that they replace. However, for both land uses it remains in how far the soil hydraulic characteristics are comparable to that of native forest. Therefore, we investigated the saturated hydraulic conductivity (Ks) and some hydrophysical soil attributes in four land-use types: (i) a shade-grown coffee; (ii) a natural regenerated forest 15 years ago; (iii) a pasture; and (iv) a reference forest, in the municipality of La Jagua de Ibirico, César department, Colombia. We determined historical land use and conducted soil sampling, using the Beerkan method to determine the Ks values. We also measured canopy cover, vegetation height, diameter at breast height and total number of trees in the forest covers. Our results indicate that Ks values were similar for the coffee and the reference forest, reflecting the positive effect of trees on soil hydrological functioning in agroforestry systems. Our results suggest that 15 years of forest regeneration after land abandonment in Sub-Andean Forest, can improve the soil hydraulic attributes. Additionally, soil water repellency was observed for the reference forest soil.

Full textAbstract:
The 1970s–1980s droughts in the Sahel caused a significant degradation of land and plant cover. To cope with this situation, populations have developed several biophysical and social adaptation practices. Many of these are agroforestry practices and contribute to the maintenance of agrosystems. Unfortunately, they remain insufficiently documented and their contributions to the resilience of agrosystems insufficiently evaluated. Many authors widely link the regreening in the Sahel after droughts to the resumption of rainfall. This study examines the contribution of agroforestry practices to the improvement of woody plant cover in the North of Burkina Faso after the 1970s–1980s droughts. The examination of practices is carried out by integrating the rainfall, soil, and geomorphology variables. Landsat images are used to detect changes in woody plant cover: increasing, decreasing, and no-change in the Enhanced Vegetation Index. In addition, 230 field observations, coupled with interviews conducted on the different categories of change, have allowed to characterize the biophysical environment and identify land-use practices. The results show a variability of vegetation index explained to 9% (R2 = 0.09) by rainfall. However, Chi-Squared independence tests show a strong dependence between changes in woody plant cover and geomorphology (p = 0.0018 *), land use, land cover (p = 0.0001 *), and land-use practices (p = 0.0001 *). Our results show that rainfall alone is not enough to explain the dynamics of agrosystems’ woody plant cover. Agricultural and social practices related to the dynamics of farmer perceptions play a key role.

<abstract> <p>This study evaluated the impact of land use and land cover changes on the water balance of the Couffo catchment (Benin) using the Soil and Water Assessment Tool (SWAT). To that end, soil, land uses, hydro-meteorological data including rainfall, temperatures (maximum and minimum), wind speed, solar radiation, relative humidity and discharge data were used as main inputs. To assess the impact of land uses on the catchment water balance, three different land uses (2000, 2006 and 2011) were used. Results showed that from 2000 to 2011, croplands and fallows increased by 34% while the shrub and grass savannahs decreased respectively by 34 and 24%. In addition, agroforestry and gallery forest decreased by 63% and 58% respectively while a rapid increase in settlement. The study outcome suggested that the SWAT provided satisfactory results for discharge with R<sup>2</sup>, NSE, KGE and absolute percent of bias (absPBIAS) ranged between (0.7–0.9), (0.6–0.9). (0.6–0.9) and (5.3–34) respectively. Moreover, the evaluation of land use and land cover changes on the catchment water balance resulted in an increase in annual surface water and water yield, while the groundwater and actual evapotranspiration (ETa) have decreased. Findings of this study may be a great contribution to water resource management in the Couffo catchment. This may contribute to better allocate water for the actual catchment population demand without dampening those of the future generation.</p> </abstract>

Purpose This paper aims at providing the evidence about how carbon sequestration in terrestrial ecosystems could contribute to the decrease of atmospheric CO2 rates through the adoption of appropriate cropping systems such as agroforestry. Design/methodology/approach Stratified randomly selected plots were used to collect data on tree diameter at breast height (DBH). Composite soil samples were collected from three soil depths for soil carbon analysis. Above ground biomass estimation was made using an allometric equation. The spectral signature of each plot was extracted to study the statistical relationship between carbon stock and selected vegetation indices. Findings There was a significant difference in vegetation and soil carbon stocks among the different land use/land cover types (P < 0.05). The potential carbon stock was highest in the vegetation found in sparsely cultivated land (13.13 ± 1.84 tons ha−1) and in soil in bushland (19.21 ± 3.79 tons ha−1). Carbon sequestration potential of the study area significantly increased (+127174.5 tons CO2e) as a result of conversion of intensively cultivated agricultural lands to agroforestry systems. The amount of sequestered carbon was found to be dependent on species diversity, tree density and tree size. The vegetation indices had a better correlation with soil and total carbon. Originality/value The paper has addressed an important aspect in curbing greenhouse gases in integrated land systems. The paper brings a new empirical insight of carbon sequestration potentials of agroforestry systems with a focus on drylands.

Full textAbstract:
How can we manage farmlands, forests, and rangelands to respond to the triple challenge of the Anthropocene—biodiversity loss, climate change, and unsustainable land use? When managed by using biodiversity-based techniques such as agroforestry, silvopasture, diversified farming, and ecosystem-based forest management, these socioeconomic systems can help maintain biodiversity and provide habitat connectivity, thereby complementing protected areas and providing greater resilience to climate change. Simultaneously, the use of these management techniques can improve yields and profitability more sustainably, enhancing livelihoods and food security. This approach to “working lands conservation” can create landscapes that work for nature and people. However, many socioeconomic challenges impede the uptake of biodiversity-based land management practices. Although improving voluntary incentives, market instruments, environmental regulations, and governance is essential to support working lands conservation, it is community action, social movements, and broad coalitions among citizens, businesses, nonprofits, and government agencies that have the power to transform how we manage land and protect the environment.

Full textAbstract:
Agricultural crop management practices that guarantee soil quality are necessary for the sustainability of agrosystems. The use of agroforestry systems to make food production viable with less loss of soil fertility is a possible alternative for sustainable agriculture. This work evaluated the chemical characteristics of an Oxisol in three systems of use and management: 1) peach for palm heart production; 2) peach palm for fruit and seed production; and 3) Urochloa decumbens pasture. In these areas, located at Fazenda Piloto of the Agricultural Sciences Department at the University of Taubaté - UNITAU, Taubaté-SP, Brazil, samples were collected at the depths 0-10cm, 10-20cm and 20-40cm. In these soil samples, levels of P, K, Ca, Mg, B, Cu, Fe, Mn, Zn, pHCaCl2, H+Al, total organic carbon and organic carbon stock were determined. The sums of bases (SB), cation exchange capacity (CEC) and base saturation (BS) were calculated. The results were subjected to analysis of variance and the means were compared using the Tukey test at 5%. The results indicate that soil cultivated with peach palm for palm heart production showed better fertility compared to peach palm for fruit and seed production and pasture. The upper layers 0-10cm and 10-20cm are the most fertile, concentrating P, Ca e Mg, high CEC, SB and BS.
