Agroforestry: Challenges and Opportunities in Rhino Camp and Imvepi Refugee Settlements of Arua District, Northern Uganda

In the past, the environment has been a low priority in humanitarian operations for refugee agencies and implementing partners because of the emergency context. However, actions to safeguard the environment can be undertaken concurrently with emergency interventions and organisations should take responsibility for conserving the environment in refugee settlements in the same way that they are responsible for the welfare of refugees. Tree-based interventions, such as agroforestry, have been demonstrated as a viable option for resilience and sustainability in landscapes with increasing human pressure. Refugee settlements are subject to intense human pressure and suffer environmental degradation as a consequence. The potential benefits of agroforestry in refugee settlements though are not well researched. This study explores the implementation of agroforestry schemes in refugee settlements in the Arua district of Uganda. Using semi-structured interviews with the beneficiaries of the International Centre for Research on Agroforestry (ICRAF) agroforestry projects in Imvepi and Rhino camps, the study identifies key benefits for participants and the environment. These include improved livelihoods and nutrition. However, there are challenges to overcome before agroforestry can be made more widely available in refugee camps. Key barriers include insufficient land, limited water availability and lack of local knowledge, which limits productivity. This research shows how relief, rehabilitation and development can work hand in hand to reduce social and environmental pressure in the targeted refugee settlements and host communities and improve the well-being of beneficiary households by creating opportunities for income generation, improving nutrition and contributing to social cohesion

Farmers\u27 Attitudes Towards On-Farm Cultivation of Indigenous Fruit Trees in Adwari Sub-County, Lira District, Uganda

This study was conducted in Adwari sub-county, Lira district to (i) determine the conservation status and threats to indigenous fruit trees (IFTs), (ii) assess farmers’ attitudes towards IFT cultivation, (iii) documents local knowledge on propagation and management of IFTs, and (iv) identify opportunities and constraints to promotion of IFTs cultivation. Semi-structured questionnaires were administered to a total of 120 randomly selected respondents. MINITAB statistical package was used to analyze the data. Logistic regression analysis was performed to show the influence of socio-economic characteristics on farmers’ towards their attitudes to plant IFTs. The population of IFTs was found to be generally declining. The major reasons for decline were charcoal burning and firewood collection. Although, majority of farmers had positive attitudes towards cultivation of IFTs, their attitudes were influenced by gender, education level, farm size and occupation status. Lack of clear markets for indigenous fruits, unclear information about their food values, lack of seedlings in local nurseries, and dearth of information propagation techniques were the major hindrance to cultivation of IFTs. There is a need especially by local governments and local councils to formulate clear strategies on conservation of IFTs for example by establishing a community nursery and propagation center for IFTs. There is a need to address the issue of marketing and pricing of indigenous tree fruit products. Lastly, there is a need of further study to analyze the market environment for indigenous tree fruits compared with alternative possibilities such as exotic fruits or agricultural crops

Trait-based approaches for guiding the restoration of degraded agricultural landscapes in East Africa

Functional ecology provides a framework that can link vegetation characteristics of various land uses with ecosystem function. However, this application has been mostly limited to [semi-]natural systems and small spatial scales. Here, we apply functional ecology to five agricultural landscapes in Kenya, Uganda and Ethiopia, and ask to what extent vegetation characteristics contribute to soil functions that are key to farmers’ livelihoods. We used the Land Degradation Surveillance Framework (LDSF), a multi-scale assessment of land health. Each LDSF site is a 10 × 10 km landscape in which vegetation cover and erosion prevalence were measured, a tree inventory was carried out, and topsoil (0–20 cm) samples were collected for organic carbon (SOC) analysis in approximately 160 × 1,000 m2 plots. Land degradation is a recurring phenomenon across the five landscapes, indicated by high erosion prevalence (67%–99% of the plots were severely eroded). We used mixed models to assess if vegetation cover, above-ground woody biomass and the functional properties of woody vegetation (weighted-mean trait values, functional diversity [FD]) explain variation in SOC and erosion prevalence. We found that the vegetation cover and above-ground biomass had strong positive effects on soil health by increasing SOC and reducing soil erosion. After controlling for cover and biomass, we found additional marginal effects of functional properties where FD was positively associated with SOC and the abundance of invasive species was associated with higher soil erosion. Synthesis and applications. This work illustrates how functional ecology can provide much-needed evidence for designing strategies to restore degraded agricultural land and the ecosystem services on which farmers depend. We show that to ensure soil health, it is vital to avoid exposed soil, maintain or promote tree cover, while ensuring functional diversity of tree species, and to eradicate invasive species

On-Farm Management of Vitellaria paradoxa

The population of shea butter tree (Vitellaria paradoxa C. F. Gaertn.)—a priority tree with enormous economic and cultural values to the parkland communities in Uganda, is rapidly declining due to rapid human population growth, increasing land fragmentation, and high demand for woodfuel especially charcoal. Reversing this trend will depend on the rural community involvement in the planting, facilitating natural regeneration, and tending of shea trees on farm. As such a survey was conducted in Amuria district, eastern Uganda, to assess local strategies and constraints to on-farm management of shea trees, and document socio-demographic factors influencing the on-farm conservation. About 93% of the households protected naturally regenerated V. paradoxa trees mainly on farms. V. paradoxa was mostly propagated through coppices and seedlings. Although insecure land tenure, insecurity, pests, disease, and shortage of planting materials were reported as major hindrances, farmsize, family size, and gender significantly (P≤0.05) influenced people’s willingness to conserve V. paradoxa. Byelaws and policies on shea conservation need to be properly enforced, and further propagation research is required especially towards shortening the juvenile period of V. paradoxa so that more farmers can start propagating the tree other than relying on its natural regeneration

Evidence-based opportunities for out-scaling climate-smart agriculture in East Africa

Climate-smart agriculture (CSA) is being widely promoted as a solution for food insecurity and climate change adaptation in food systems of sub-Saharan Africa, while simultaneously reducing the rate of greenhouse gas emissions. Governments throughout Africa are writing policies and programs to promote CSA practices despite uncertainty about the ability for practices to meet the triple CSA objectives of CSA. We conducted a systematic review of 175 peer-reviewed and grey literature studies, to gauge the impact of over seventy potential CSA practices on CSA outcomes in Tanzania and Uganda. Using a total of 6,342 observations, we found that practice impacts were highly context (i.e. farming system and location) specific. Nevertheless, practice effect across CSA outcomes generally agreed in direction. While our results suggest that CSA is indeed possible, lack of mitigation data precludes a more conclusive statement. Furthermore, the inclusion of potential adoption rates changes the potential of CSA practices to achieve benefits at scale. Given the uncertainty and variable impacts of practices across regions and outcomes, it is critical for decision makers to prioritize practices based on their desired outcomes and local context

THE POTENTIAL FOR FOREST LANDSCAPE RESTORATION IN DEGRADED FARMLANDS: Filling knowledge gaps on the restoration of degraded smallholder landscape mosaics

The main objective of this work package was to illustrate the utility of comparative studies in scaling up forest landscape restoration (FLR) projects by combining systematic field-based methodologies with advanced remote sensing analyses to provide real-time as well as past assessments of key indicators of land degradation. These methods and approaches allow for the prediction of indicators of ecosystem health to be made for large landscapes
