Smallholder farmers’ willingness to pay for multi-stress tolerant varieties
Open AccessHambulo Ngoma, Kelvin Mulungu et al.ARTICLEClimate and Development2026
Several biotic and abiotic factors constrain progress in African agriculture. We assess the prevalence of and farmers’ willingness to pay (WTP) for varieties tolerant to fall army worm (FAW) Spodoptera frugiperda (J.E. Smith) in maize (Zea mays), rust disease in Soybean (Glycine max) and rosette disease in groundnuts (Arachis hypogaea) using experimental auctions. Pest/disease incidences varied across the three countries during the 2022/2023 seas…
Smallholder farm management under evolving land institutions
Open AccessJudith Chamberlin, Jordan Chamberlin et al.ARTICLELand Use Policy2026References: 35
In Zambia, clearing land for cultivation is a reported mechanism for making land claims in contexts of uncertain rights and expropriation risk, and leaving land fallow is less common for those with weaker land rights. When only some farmers in a village obtain land title, the land security of untitled landholders, particularly women, can become less secure in contexts where there are fears that chiefs can reallocate land away from untitled smallh…
Motivations and incentives for mechanization in Zambia
Open AccessKelvin Mulungu, Lushomo Molly Ngoma et al.ARTICLECogent Social Sciences2025
Smallholder farmers in Zambia face low agricultural productivity, and while tractor mechanization offers a solution, adoption rates remain low. The contextual factors driving this low uptake, including farmers’ preferences for different ownership and financing models, are not well understood. This study uses a mixed-methods approach, including surveys with 208 farmers, 18 focus group discussions (FGDs) and 28 key informant interviews (KIIs) acros…

Climate shocks, vulnerability, resilience and livelihoods in rural Zambia
Open AccessHambulo Ngoma, Arden Finn et al.ARTICLEClimate and Development2024
Climate and weather shocks pose risks to livelihoods in Southern Africa. We assess the extent to which smallholders are exposed to climate shocks in Zambia and how behavioural choices influence the negative effects of these shocks on vulnerability and resilience. We use household data from the nationally representative Rural Agricultural Livelihoods Survey and employ an instrumental variable probit regression model to control for the endogeneity …

Smallholder farmers' willingness to pay for two‐wheel tractor‐based mechanisation services in Zambia and Zimbabwe
Open AccessHambulo Ngoma, Paswel P Marenya et al.ARTICLEJournal of International…2023
Mechanisation is back among top development policy priorities for transforming African smallholder agriculture. Yet previous and ongoing efforts ubiquitously suffer from lack of scientific information on end‐user effective demand for different types of mechanical innovations to inform public investment or business development programmes. We assess smallholder farmers' willingness to pay (WTP) for two‐wheel tractor (2WT)‐based ripping, direct seed…
