There has been a dramatic decline in cocoyam production in Nigeria in recent years due to climate related stressors. We investigated the nature and extent of these impacts and the resilience building strategies used by cocoyam farmers in Nigeria. Data were collected from the farmers in 2010 and 2017 and from FAO statistical database. Results show a yield decline from 8mt/ha in 2005 to 4mt/ha in 2016, due to acid rain, causing bleaching of cocoyam leaves, die back, smaller tubers, early decay of the tubers and decline in the quality and taste of the tubers.

The study investigated gender in wholesale smoked-fish marketing in Kanji Lake Basin, Nigeria. Specifically, the study identified roles of  individual actors in fish marketing, determined the profitability of fish marketing, analyzed the marketing efficiencies and estimated gaps  in the fish marketing chain. A two-stage sampling procedure was used to select 60 wholesale smoked-fish marketers from 13  communities. Primary data were collected from wholesale smoke-fish marketers using an interview schedule.

Food security remains a major concern, as efforts to commercialise and specialise in agricultural production have been constrained. This is partly due to land scarcity, compelling smallholder farmers to operate on fragmented lands. Land reforms that seek to consolidate lands and promote crop specialisation can be welfare-enhancing because they can stimulate investment in agricultural innovation.

Specialization and intensification have been the main focuses of agricultural development and modernization for decades, among those who claim that doing so will increase agricultural output. Specialization and commercialization in agriculture are linked to greater efficiency than subsistence farming, as these can boost the production and competitiveness of smallholder farmers. However, in recent years, some have questioned this model's resilience and long-term viability.

AbstractWe contribute to the inverse farm size-productivity puzzle (IR) literature by examining the relationship using a unique data set from southern Ghana that covers farms between 5 and 70 ha. The study uses an instrumental variable (IV) for land size to mitigate some effects of measurement error in land size. The inverse relationship between farm size and farm productivity is upheld when ordinary least squares estimators (OLS) are applied but becomes insignificant although still negative in the IV estimation. The results show that measurement error in land size attenuates the IR.

Background: The study was motivated by the lack of poultry waste management policy in Nigeria to develop better initiatives for the development of green and alternative energy sources to mitigate climate change. Multiplicities of researches have neglected the research in this area despite the environmental health concerns and benefits associated with it. Methods: The study was conducted in 2019. Three states with a high concentration of poultry farmers in South East Nigeria were selected. A multi-stage sampling technique was used to select poultry farmers and policy actors for the study.

In Nigeria, agriculture plays a critical role in the economy and remains the key to the country’s economic diversification plan. However, the agricultural sector is facing numerous challenges such as climate change, widespread insecurity, price volatility, poor government policies and the emergence of COVID-19 pandemic has further exacerbated the already existing problems.

The COVID-19 pandemic has caused disruptions to global food supply chains. It has led to severe economic stress and malnutrition particularly in developing countries. This paper outlines the impact of COVID-19 pandemic on agriculture and livelihoods in Nigeria, measures put in place by the Nigerian Government to cushion the effect and parses evidence on programmes and policies that can help speed up sustainable economic recovery that Nigeria desperately needs post COVID-19 pandemic, through agricultural growth.
