Rapid uptake of greenhouse gas (GHG) mitigation measures is central to reducing agricultural and land use emissions and meeting the UK Net Zero policy. The socioeconomic challenges and barriers to uptake are poorly understood, with yet unclear structural pathways to the uptake of GHG mitigation measures. Using an online survey of 201 agricultural l...

The promotion of improved maize varieties and chemical fertilisers underscores many policy approaches addressing multiple production risks such as poor soil fertility and drought. However, the unsustainable use of chemical fertilisers has important implications for soil degradation. The synergies between improved maize varieties and sustainable lan...

Background In Sub-Saharan Africa, drought is one of the prevailing climatic conditions that has led to the modification of improved seeds to be resilient enough to improve yield and increase farm households' welfare. However, like most climate-smart agricultural practices, the adoption of drought-tolerant maize varieties is low. This study examines...

While the impact of land tenure security on farm yield has been extensively investigated in the literature, little is known about the role tenure security plays in mitigating risk exposure. Using a nationally representative dataset collected through a multistage stratified random sampling of 1820 maize farmers in Nigeria during the 2014/ 2015 produ...

This review brings to light, extensive body of research on the evolvement of agricultural technology in Sub-Saharan Africa with focus on adoption studies in West and East Africa countries. The review highlights historical green revolution events and the heterogeneity in the determinants of the adoption of agricultural technology. Three key popular...

Soil fertility depletion is acknowledged to adversely influence agricultural productivity and welfare status of rural farming households. Studies have shown that organic fertilizer utilization tends to rejuvenate the soil, thereby enhancing its productive capacity. This study seeks to estimate the welfare impact of organic fertilizer adoption among...

Studies have shown that climate change adaptation options (CCA) are implemented to buffer the unfavorable climatic changes in Nigeria causing a decline in food security. Against the background of measuring the impact of CCA options using cross-sectional data, this study assessed how CCA had affected food security using panel data on farming househo...

Despite the important roles of Sustainable Agricultural Practices (SAPs) in improving productivity, welfare, and food security of farming households, the adoption rates of SAPs have been perceived to be generally low, especially in developing countries. Using cross-sectional data collected from the 2015 Nigeria General Household Survey, this study...

The challenge of food security in Nigeria hinges on several factors of which poor technical efficiency is key. Using a stochastic frontier framework, we estimated the technical efficiency of agricultural households in Nigeria and tested for the significance of mean technical efficiency of food-secure and food-insecure agricultural households. We fu...
