Item Application of the TOA-MD model to assess adoption potential of improved sweet potato technologies by rural poor farm households under climate change: the case of Kabale district in Uganda(Food Security, 2014) Ilukor, John; Bagamba, Fredrick; Bashaasha, BernardSweet potato technologies that increase productivity, such as drought resistant varieties and virus free planting material are being promoted in order to reduce the vulnerability of poor farm households to climate change. In this paper, the Trade-off Analysis, Minimum Data Model Approach (TOAMD) was used to assess the adoption potential of these technologies by resource poor farmers under climate change in Uganda. The model was calibrated and validated using household survey data collected in 2009 from Kabale district. To simulate adoption potential, the base system data was generated from household data and adjusted to reflect impact of climate change on crop yields and prices by 2050. The percentage increase in yields resulting from the use of climate resilient sweet potato technologies were used to estimate yields for alternative systems based on the results from sweet potato trials by the National Agricultural Research Organization (NARO), Uganda. Adoption potential of sweet potato technologies varied across altitudes. Compared with the high and lower altitudes, adoption potential is lowest at moderate altitude despite higher yields and lower costs of production. Paying farmers to adopt new sweet potato technologies is economically rational at the higher and moderate altitudes but not at the lower altitudes. The provision of free planting material (subsidy) for the evaluated technologies resulted in a modest increase of 2 % in adoption potential. Therefore, providing this as a way of increasing adoption of sweet potato technologies to reduce vulnerability of poor farm households to climate change will have a very small impact. Instead, climate change adaptation policy should focus on creating enabling environments for farmers tomarket their produce so as to raise returns and reduce the opportunity costs of climate change adaptation strategies.Item Impact of creative capacity building of local innovators and communities on income, welfare and attitudes in Uganda: a cluster randomized control trial approach(International Initiative for Impact Evaluation, 2019) Nkonya, Ephraim; Bashaasha, Bernard; Kato, Edward; Bagamba, Fredrick; Danet, MarionTechnologies and innovations are a key driver of human developments and competitiveness. Failure of imported technologies has galvanized efforts on technologies generated by close collaboration between external investors and local committees. The general objective of the study was to determine the impact of Creative Capacity Building (CCB) training on human welfare and local communities’ perception on their ability to innovate. Specifically, the study targeted a number of major outcomes of CCB training namely, economic impacts, behavioral changes, attitudinal change and technology creation and use including policy influence. CCB is a hands-on training approach whose students are community members with any educational level. CCB focuses on harnessing local creativity and indigenous knowledge in the technology design process, facilitating community innovations and invention. In skills training workshops, trainees work collaboratively to design and develop tools that meet their needs. The training encourages and trains people to make technologies that generate income, improve health and safety, save labour and time and change perceptions about themselves.Item Pathways to sustainable intensification of the coffee-banana agroecosystems in the Mt. Elgon region(Cogent Food & Agriculture, 2019) Sebatta, Christopher; Mugisha, Johnny; Bagamba, Fredrick; Nuppenau, Ernst A.; Domptail, Stephanie E.; Kowalski, Benjamin; Hoeher, Matthias; Ijala, Anthony R.; Karungi, JeninahDespite the importance of coffee and banana as key income and food sources for millions of farmers inhabiting the densely populated East African highlands as well as and urban dwellers, there are declining yields. One of the causes for this decline is increased soil degradation that has led to recent conversions of more forest land into crop land in marginal and sensitive mountain ecosystems. However, evidence shows that only a few households manage the desired shift to sustainable production systems, mainly due to social, economic and environmental constraints. In this study we therefore, set out to find out typologies of coffee-banana farms based on intensification levels and pathways taken using a number of agricultural intensification surrogate indicators. We also sought to find the driving factors and barriers for intensification. Using Principal Component, cluster and Pearson correlation analyses, and later both a Generalised Linear and Multinomial Logit models, results revealed four distinct intensification pathways, one of which is a high-inputhigh- output conventional pathway and the other three were low-to-medium input agroecological pathways. Adoption of an intensification pathway could be impeded by geographical location, wealth status in form of livestock, land and lack of credit access. We found the hypothesis that resource-rich farmers intensify by capital investments, while the resource-constrained farmers intensify through labour true for the conventional and agroecological intensification pathways respectively. The existence of intermediary pathways under the agroecological classification creates opportunities for interventions that target to increase yields while reducing degradation and negative environmental impacts of agriculture.
