Article
Improved cultivars and agronomic practices have significantly increased chickpea production in Ethiopia in recent decades. Enhanced availability of chickpeas in Ethiopia, therefore, contributes to food, nutrition, and income security of the country. However, we know relatively little about the extent to which farmers have harnessed the full potenti...

This paper investigates the welfare impacts of improved groundnut adoption in Ghana, Mali, and Nigeria using three-year balanced panel data collected from 2,868 households. We apply the Cragg double hurdle model to understand the adoption process and a fixed-effects instrumental variable approach to estimate the impact on gross margins, household i...
Article
Full-text available
It is understood that the grain market pulls the seed market. The problem of low quality prompted failure of traders and processors to purchase most of the farmers’ grain to subsequently drive the use of improved variety seed. The aim of this study is to identify drivers that persuade farmers to use improved variety seeds for grain production. It a...

Background Seed systems are considered as a vehicle through which the sustainable agricultural intensification can be achieved. However, most sub-Saharan African countries have been ineffective to provide sufficient incentives for stakeholders to consistently invest in the seed systems specifically for crops like sorghum. This study was therefore c...

Yields of groundnut in Tanzania are reported to be 2.5 to 3 times lower than other African countries. Use of obsolete varieties, unreliable rains, disease and insect pests' infestation and poor agronomic practices are some of the causes. To address these issues and to contribute to better nutrition and increased incomes of 14 million people depende...
Article
Considerable research documents why women farmers have lower technology adoption rates than men farmers, but relatively little is known about what happens within a household after technology uptake. This study contributes through an investigation of the intrahousehold distribution of benefits and costs of agricultural technology adoption in western...

The management of rangelands, including climate change adaptation strategies, is primarily responsible for stimulating livestock productivity, which consequently improves food security. This paper investigates the impact of climate change adaptations on food security among pastoralists in semi-arid parts of Kenya, who have not received due attentio...
Preprint
Full-text available
The paper investigates the impact of climate change adaptation on food security in the Semi-Arid parts of Kenya. Our research used a sample of 440 households, and an endogenous Switching regression is estimated to account for the heterogeneity in the decision to adapt or not, and for unobservable characteristics of pastoralists. We examined how pas...
Conference Paper
Full-text available
Low agricultural productivity in sub-Saharan Africa has been associated with poor uptake of modern farming technologies like improved crop varieties. However, actual adoption of improved crop varieties is unclear because past empirical studies have relied on subjective self-reported adoption status that could be inaccurate. Weak seed systems have n...
Article
Full-text available
The adoption of improved sorghum technologies by smallholder farmers is still low in Tanzania. Many farmers fail to acquire quality inputs due to different underlying reasons. This article analyzes factors underlining the adoption of improved technologies among sorghum farmers in Tanzania and evaluates profitability of grain production. A total of...
Article
Full-text available
Poverty among smallholder farmers in sub-Saharan Africa has been associated with low agricultural productivity emanating from gender yield gaps among other factors. Using data collected from smallholder groundnut producers in Nigeria, we analyzed the gender yield gap by applying the exogenous switching regression (ESR) model and Oaxaca-Blinder (OB)...

Wheat is fundamental to human civilization and has played an outstanding role in feeding a hungry world and improving global food security. The crop contributes about 20 % of the total dietary calories and proteins worldwide. Food demand in the developing regions is growing by 1 % annually and varies from 170 kg in Central Asia to 27 kg in East and...

Many Sub-Saharan African countries have liberalized their economies and developed poverty reduction strategies aimed at opening up new market-led opportunities for economic recovery and accelerated growth. The outcomes of these policy reforms have, however, been quite mixed (Winter-Nelson and Temu 2002; Dorward and Kydd 2004; Fafchamps 2004). Many...

The history of producer organizations in sub-Saharan Africa (SSA) is a mixed one. In the past, producer organizations often failed to provide desired services due to dependence on government support, which led to heavy political interference as well as internal leadership and managerial problems. However, the hasty retreat of the state following ad...
