“…This is not surprising because most farmers depend on agriculture for their subsistence and cash incomes and are unwilling to engage in practices that risk reducing crop production (Muschler and Bonnemann 1997;Mukadasi et al 2007). The forestry blocks were generally located on marginal land where there was no active agriculture and where opportunity costs were low.…”

Agroforestry on small-scale farms has potential to provide important ecological services, such as carbon sequestration and maintenance of biological diversity, while also providing on-farm products for domestic use and marketing. Payments for environmental services (PES) are an increasingly popular mechanism for encouraging production of ecological services on agricultural lands and may also contribute to poverty reduction and sustainable farming practices through adoption of new farming technologies. There is little current information, however, on the degree to which PES increase tree planting relative to a baseline or the effects of program participation on farmer livelihoods. This study examined the initial impacts of a recent PES program for agroforestry in southern Costa Rica by: (1) assessing the efficiency of PES in increasing reforestation relative to baseline tree planting activities; (2) examining farmer perceptions of socioeconomic and environmental impacts of PES; and (3) exploring obstacles to adoption of agroforestry practices. Thirty-six participant and non-participant farmers were given semi-structured interviews. Key informant interviews were conducted with forestry engineers, farmers' associations, NGOs, and government agencies. Farmers reported positive economic benefits in the first 2-3 years of program participation. PES participants also planted substantially more trees and more species than non-participant farmers. The PES program was effective in overcoming initial economic and technical obstacles that made adoption of agroforestry unattractive. Strong local organizations played a key role in facilitating adoption. Additional investment in short-to medium-term technical support will likely be necessary for broad retention of agroforestry practices beyond the life of the PES contracts.

“…Attitudes toward the conservation of species are, however, species-specific [ 26 ] and depend on several factors including the socio-demographic profiles (gender, age, education, ethnicity, etc.) of local people [ 19 , 27 ], their geographical location and preferences (local importance of species: UV, market value) [ 28 ], and their knowledge on the species biology [ 29 , 30 ]. Traditional conservation and management actions are diverse and may range from plantations where a species is deliberately planted, to assisted natural regeneration (ANR).…”

Background Carapa procera , Lophira lanceolata , and Pentadesma butyracea are three underutilized but increasingly threatened indigenous oil-seed tree species (IOS) in tropical Africa. Because local knowledge is vital for sustainable management, this study investigated the socio-economic factors that explain local people’s (i) preferences for these IOS, (ii) attitudes toward their conservation, and (iii) ability to identify “plus trees” based on seed traits. We predicted a positive relationship between response variables and informants’ age, residence status, gender (femaleness), and existence of market opportunities for each IOS. We also predicted that a higher preference for a given IOS has a positive effect on people’s attitudes for its conservation and the aptitude to identify its “plus trees.” We additionally expected significant differences among ethnic groups for each response variable. Methods Data were collected through individual semi-structured interviews with 336 informants from 14 randomly selected villages in the species distribution area of Kénédougou province. For each species, the collected data were the number of actual uses reported (converted to use value—UV, as a measure of the species preference), practiced conservation actions (converted to conservation attitude using a four-scale scoring method), and possible criteria for selecting preferred trees for seed oil extraction. Generalized linear mixed models were used to test for the fixed effects of socio-economic factors, and account for the random variation across villages. Results The results showed species-specific patterns. Carapa procera had the highest UV and hence was the most preferred IOS, particularly by women. Informants from the Siamou ethnic group had the highest UV irrespective of IOS. The most cited conservation actions were assisted natural regeneration and banning of tree cutting, which were practiced for C. procera and L. lanceolata . No conservation measure was cited for P. butyracea . The practice of tree planting was not recorded for any of the IOS. Young and male informants participated less in conservation actions. Tree selection for oil-seed collection was mainly guided not by “oil extraction yield” but rather by the “quality of extracted oil” (namely oil color and taste for food uses, and oil bitterness for medicinal efficacy). The selection mainly concerned L. lanceolata and was mostly practiced by elderly people. Conclusion This study provided useful local knowledge-based information to guide conservation actions and valorization strategies of three IOS. The study sheds further light on the socio-economic factors that are associated to local people’s preferences, conservation attitudes, and individual tree select...

“…The area experiences bimodal rainfall pattern with an annual precipitation of between 1000mm to 1600 mm (Opedes et al, 2022;Nakileza & Nedala, 2020). The mean average temperature ranges from 15˚C to 23˚C (Opedes et al, 2022;Graham et al, 2021;Mukadasi et al, 2007). In regards to vegetation, Tsume shares similar vegetation characteristics as the entire Elgon region.…”

Landslides continue to occur in the Elgon region despite interventions such as tree planting initiatives aimed at restraining them. The current study assessed the mechanical properties of six selected agroforestry tree roots on slope stability with a keen focus on root tensile strength, soil shear strength, and index of root binding. A standard deviation ellipse method was applied to model the spatial distribution patterns of selected agroforestry trees. Tree-landslide relationship was tested using the Pearson correlation method while root tensile and soil shear strength with a one-way (ANOVA) and descriptive statistics respectively. Species distribution results indicate a high dispersion rate of Croton macrostachyus and Markhamia luteaacross the study area and high concentration of Albizia coriaria downstream. A weak negative correlation (r = -0.20 < 0.01) was reported between diameter at breast height and landslide size. Tensile strength results observed a significant difference among species with (F (5, 573) = [18.161], p < 0.001) and Grevillea robusta (3.02±1.217kg/mm²), Albizia coriaria (2.53±1.382kg/mm²), and Markhamia lutea (2.28±1.01kg/mm²) as the best performers. The best shearing species was Albizia coriaria with average shear strength (52.46±10.24) kpa followed by Markhamia lutea (50.70±15.47) kpa. The Eucalyptus spp. on the other hand underperformed with average shear strength of (46.75±12.92) kpa. In conclusion, the presence of trees reduces landslide risk in an area and DBH is a very important guiding factor. Grevillea robusta, Albizia coriaria, andMarkhamia lutea emerged as best performers in terms of root tensile strength and soil shear strength hence their suitability for enhancing slope stability. However, Eucalyptus Spp., which is widely favoured in the region for its rapid growth was the worst performer with very low shear strength. Therefore, careful consideration of the tree characteristics is essential during promotion campaigns for slope stability in fragile environments.
