From tradition to transition
Sustainable diets are increasingly central to global food systems research, yet evidence from low- and middle-income countries remains limited. This study assesses changes in the sustainability of Ugandan household diets from 2005 to 2020 employing a new Sustainable Diet Index (SDI) encompassing healthfulness, environmental impact, cultural appropriateness, and economic affordability. Using nationally representative data, we found that diets beca…
Consumer behaviour and edible insect snacks in East Africa
Purpose We investigate consumer behaviour toward sustainable insect-based foods in East Africa, with a specific focus on grasshopper and cricket snacks in Uganda and Kenya. Notably, we examine the intention–behaviour gap, exploring the factors that contribute to discrepancies between consumers’ stated intentions and their actual consumption behaviour. We further evaluate the influence of attitude, perceived norms and perceived behavioural control…
Agroecological sustainability of traditional green leafy vegetable value chains in central Uganda
Diversifying food systems with traditional green leafy vegetables can enhance food and nutrition security in sub-Saharan Africa. However, the sustainability of these value chains, especially in informal markets, remains underexplored. This study assessed sustainability using agroecological principles within a value chain analysis framework. Data from 287 producers and 36 traders in Uganda showed that vegetable chains only partially align with the…
Contribution of the Baobab Value Chain to Equitable Rural Livelihoods and Poverty Alleviation in Ghana
Non‐timber forest products (NTFPs) are central to income diversification and livelihood resilience in Sub‐Saharan Africa. However, the welfare implications of baobab commercialisation remain underexplored. This study addresses this gap by analysing the contribution of the baobab value chain to household income, poverty reduction, and income inequality across regions, actor groups, and genders in northern Ghana. Using household‐level data of 808 a…
Impact of integrated soil fertility management on maize yield, yield gap and income in northern Ghana
This paper analyzes the impact of integrated soil fertility management (ISFM) on maize yield, yield gap and net income in northern Ghana using an inverse-probability-weighted regression adjustment (IPWRA). In this study, ISFM is restricted to the adoption of crop rotation (CR), inorganic fertilizer (FT), and farmyard manure (MN) either in isolation or in combination. We find a synergy in yield gain (86.52% increase in yield) and a decrease in yie…
Off-farm work and technical efficiency of wheat production
This study analyzes the impacts of off-farm work on the technical efficiency (TE) of wheat production, using data collected from 549 farming households in China. Unlike previous studies that only capture one dimension of off-farm work, in this study, we consider multiple dimensions, including off-farm work participation status of household heads, location choices (local or migrated off-farm work), and off-farm work intensity. We employ the stocha…
Land tenure and investment in productive inputs in Ghanaian cocoa farming
Does Adoption of Information and Communication Technology Reduce Objective and Subjective Well-Being Inequality? Evidence from China
Income inequality and distribution patterns in the cassava value chain in the Oyo State, Nigeria
Purpose This study analyses income inequality and distribution patterns among key actors in the cassava value chain. The study also identifies factors that influence profit of key actors in the cassava value chain. Design/methodology/approach The study was conducted in Oyo State, Nigeria, using primary data from 620 actors, consisting of 400 farmers, 120 processors and 100 traders in the cassava value chain. The Gini coefficient was used to estim…
Farming under irrigation management transfer scheme and its impact on yield and net returns in Ghana
This article analyses smallholder irrigation management transfer (IMT) scheme participation and its impacts on yield and net farm returns of rice farmers in northern Ghana. We apply the endogenous switching regression and control function approaches to account for both observed and unobserved policy-relevant drivers of farmers’ decision to participate in IMT and potential endogeneity. Our results show that farmers’ participation in the IMT scheme…
Fertiliser adoption and sustainable rural livelihood improvement in Nigeria
Microcredit and gender empowerment
Sustainable agricultural development requires capital investment. However, farmers in Africa are constrained by inadequate access to microcredit. Therefore, this article examines the extent to which gender influences access to microcredit. The empirical results showed that women are less likely to be able to access microcredit, compared to men. The study also found that separate sets of factors including assets endowment, socio-economic, institut…
Saving behaviour of citrus farmers in Ghana
This article reports on a study that examined the saving behaviour of farmers in southern Ghana, using a sample of 100 citrus farmers. Probit and Tobit models were used in determining the factors that influence farmers’ saving behaviours and amount of saved, respectively. The empirical findings showed that age, household size, dependency, marital status, distance to financial institution, transport cost and congestion exerted significant negative…
