Item Adoption of Sustainable Agriculture Intensification in Maize-Based Farming Systems of Katete District in Zambia(Land, 2022) Hamazakaza, Petan; Kabwe, Gillian; Kuntashula, Elias; Egeru, Anthony; Asiimwe, RobertSustainable agricultural intensification (SAI) has been hailed as the solution to increasing crop productivity among farmers. Despite the significant promotion, there still remains a dearth of information on the adoption and intensity of SAI in Zambia. This study sought to identify factors that influence farmers’ adoption of SAI practices and intensity of use. A cross-sectional survey was conducted among 300 smallholder farmers of Katete district in Zambia. The Cragg’s double hurdle model was used to assess the key decision factors for SAI adoption and intensity of use. Empirical estimates revealed that limited years of farming and smaller total cropped field size were statistically significant decision factors that led to a reduced likelihood of SAI adoption. The results of the truncated model showed that smaller farm sizes and limited access to farmer extension services reduced the adoption intensity of SAI practices, whereas farmer affiliation with farmer associations and farmer training in crop production increased SAI adoption intensity. We recommend an increase in farmer training on and sensitization to the benefits of SAI practices aligned to their respective landholdings.Item Interconnectedness of Ecosystem Services Potential with Land Use/Land Cover Change Dynamics in Western Uganda(Land, 2022) Kaheesi Kusiima, Samuel; Egeru, Anthony; Namaalwa, Justine; Byakagaba, Patrick; Mfitumukiza, David; Mukwaya, Paul; Mensah, Sylvanus; Asiimwe, RobertUnderstanding the evolution of land use/land cover change (LULCC) and how it shapes current and future ecosystem services (ES) supply potential remains critical in sustainable natural resource management. Community perception of historic LULCC was reconciled with previous study via remote sensing/geographical information systems using recall data in the Budongo–Bugoma landscape in Uganda. Then, a CA-Markovian prediction model of a LULC situation in 2040 under business as usual (BAU) and forest restoration scenarios was constructed. Additionally, we assessed the perceived proximate and underlying drivers of LULCC, and how LULCC shapes ecosystem services potential using household surveys. The perceived LULCC trend for the past three decades (1990–2020) corresponded with previous studies showing grassland, bushland, tropical high forest, and wetland cover declined greatly, while subsistence farmland, commercial farmland, and built-up areas had a great increment. The predicted LULC under (i) the business as usual scenario showed a continued decline of natural LULC while anthropogenic LULC increased greatly, tending to cover half of the landscape area; (ii) forest restoration under different levels showed an improvement of forest cover and other native LULC classes with a decline in mostly subsistence farmland. The proximate drivers were in three principal components (soil infertility, subsistence farming, drought; infrastructural development, commercial farming, overstocking of livestock, pest and disease challenges; tree planting), while underlying drivers were in two principal components (technology adoption, corruption of environment stewards, policy implementation gaps; cultural gaps). Food and cash crops were perceived to be the most important ecosystem services in the landscape. Generally, the landscape ES supply potential was dwindling and predicted to continue with a similar trend under BAU, despite the increment in ES contribution of subsistence and commercial farmland. Forest restoration would slightly improve the landscape ES potential but would cause a decline in subsistence farmland, which would result in either a threat to food/livelihood security or a livelihood shift. We recommend combined interventions that seek to achieve a progressive frontier that achieves development needs and priorities based on national need such as food security through local level production with recognition for sustainable availability of ecosystem services.Item Micro-level analysis of climate-smart agriculture adoption and effect on household food security in semi-arid Nakasongola District in Uganda(Environmental Research: Climate, 2022) Egeru, Anthony; Mwesiga Bbosa, Martha; Siya, Aggrey; Asiimwe, Robert; Mugume, IsaacClimate-smart agriculture (CSA) is fronted as a sustainable, transformative, and technologically innovative approach that increases agricultural productivity, income and enhances greenhouse gas mitigation. However, there is limited micro-level evidence on the effects of the adoption of CSA on food security despite intensified promotion efforts in Uganda. A cross-sectional household survey among 165 respondents, undertaken in August–September 2020, was used to collect requisite data. Principal component analysis (PCA) with iteration and varimax rotation and analysis of variance were used in characterizing CSA practices. An ordered logit model was applied to identify the reported levels of CSA utility. Meanwhile, an endogenous switching regression was adopted to determine the effect of CSA adoption on household food security. Results showed that households used a combination of practices, including soil and water management, pasture management, livestock productivity and disease management. The PCA results revealed six major categories for the 16 most commonly used CSA practice combinations. The key factors that influenced the adoption of CSA practices among households included; access to climate information, total livestock units, ownership of non-livestock assets, and participation in off-farm activities. Results also revealed that the expected food consumption scores (FCS) for adopters and non-adopters were 53.87 and 66.92 respectively. However, when adopters and non-adopters were compared, we found that the adopters of CSA practices would have had a significantly lower counterfactual FCS had they not adopted CSA. While the adoption levels of CSA in this study is low, the counterfactual effects have shown that households that adopted CSA would have had a lower FCS and therefore lower food security status had they not adopted CSA. We recommend CSA promotional efforts that give more attention to combined CSA practices and respond to local production constraints.Item Preferred Attributes for SustainableWetland Management in Mpologoma Catchment, Uganda: A Discrete Choice Experiment(Land, 2022) Bunyangha, Jackson; Muthumbi, Agnes. W. N.; Egeru, Anthony; Asiimwe, Robert; Ulwodi, Dunston W.; Gichuki, Nathan. N.; Majaliwa, Mwanjalolo. J. G.Sustainable wetland management is a focus of many countries worldwide. These mainly use protection as a key policy directive for conservation. However, avoidance directives tend to disenfranchise local populations. Thus, such management is often resisted and rarely effective. Tailoring management strategies to user preferences allows conservation to support community livelihoods for sustainable development. This study employed a discrete choice experiment to determine the wetland management attributes preferred by residents of Mpologoma catchment as a prelude to developing a co-management system. Listed in descending order, attribute preferences were paddy farmers’ schemes, fish farming, education and research, protected wetland area, and recreation and tourism. Respondents’ characteristics influenced their choices. Older adults were more likely to support fish farming. In contrast, existing paddy farmers tended to resist such focuses and an increase in protected wetland area. Additionally, respondents with higher education were opposed to paddy farmers’ schemes, and the preference for education and research was positively influenced by respondents’ income. Respondents were willing to pay between $0.64 and $1.76 per household for each unit improvement in the preferred attribute. Our results underscore the role of DCEs in unlocking individuals’ attribute preferences, whose integration into co-management systems can be important for sustainable wetland conservation.Item The role of camel production on household resilience to droughts in pastoral and agro-pastoral households in Uganda(Pastoralism, 2020) Asiimwe, Robert; Ainembabazi, John Herbert; Egeru, Anthony; Isoto, Rosemary; Aleper, Daniel Knox; Namaalwa, Justine; Diiro, Gracious M.Recurrent and prolonged droughts have exacerbated the problems of pasture and water scarcity in arid and semiarid lands (ASALs), hence, the need for immediate and long-term adaption strategies to such shocks. Camels are increasingly being integrated into mainstream livestock production systems as an adaptation strategy to droughts. However, rigorous empirical evidence remains scarce on the role of camel-rearing in household resilience to droughts. This study used cross-sectional data from 116 households in the Karamoja sub-region of Uganda to examine the effect of camel adoption on household resilience to drought. Resilience to drought was measured as an index constructed from consumption- and income-smoothing indicators using the principal component analysis (PCA) method. The effect of camel adoption on household resilience to droughts was estimated using Lewbel’s estimator. Descriptive statistics show that camel tropical livestock units (TLUs) constituted 25% of the total TLUs of the herd among adopting households. PCA analysis shows that income-smoothing factors (increased off-farm income and alternative sources of income) had the greatest contribution to resilience. Econometric results show that a unit increase in the proportion of camel TLUs significantly increased household resilience to droughts by 20%. The study recommends increased emphasis on income diversification both on-farm and off-farm across programmes that aim to build pastoral household resilience to droughts.Item Socio-economic determinants of pastoralists’ choice of camel production in Karamoja sub-region, Uganda(Pastoralism, 2017) Biira Salamula, Jenipher; Egeru, Anthony; Asiimwe, Robert; Knox Aleper, Daniel; Jjumba Namaalwa, JustineCamel production is a potential avenue for improved food and income security in dryland areas of East Africa. Despite this potential, there is a dearth of information on the increasing choice of camel production among pastoralists in the region. Camel-owning households were obtained through snowball sampling approach whereas those without camels were obtained randomly in the vicinity of those who had camels. A total of 116 respondents were interviewed in Moroto and Amudat districts of the Karamoja sub-region, Uganda. Descriptive statistics and binary probit regression analysis were conducted on the data. Results showed that 45% of the sampled households owned camels with an average camel holding of 17.96 ± 22.12 heads. There were more cows (9.67 ± 12.368) than bulls (3.85 ± 7.149) in the camel herds. Only 8% and 26% of camel herders had access to extension services and financial credit respectively. The binary probit regression model revealed that age of the household head, household size, on- farm income and herd size significantly influenced the decision to undertake camel production in the region. Furthermore, all the household members were engaged in different camel management activities; however, herding was mainly the responsibility of the children (34.9%) and adult males (32.1%). Milking was mainly done by women (33.6%) while disease management was done by adult males (48.7%) and the elderly (22%) in the household. Provision of higher milk quantities (44.3%) and camels being in the lineage (13.6%) were cited as the key motivations for camel rearing. On the other hand, 56% of respondents observed that the initial high cost of camel acquisition was the main limitation to owning camels. This study has shown that decision-making in transitioning to camel production in Karamoja is a result of socio-economic attributes including pastoralists’ perceptions of associated costs and benefits arising from camel production. Therefore, it is vital to strengthen innovative financing mechanisms and traditional systems such as agistments that can support pastoralists willing to acquire camels. There is need for extension services that target camel rearing where women and children are involved given their central role in camel management.
