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.

The study examined the determinants of technical efficiency among lowland rice farmers in Enugu State, Nigeria. Primary data were sourced from rice producers through the use of well designed questionnaires. The study was conducted in four agricultural zones of Enugu State, during the 2017/2018 cropping season. Multistage and simple random sampling technique was employed to select 300 sampled rice farmers for the study.

ABSTRACT

Background: Obesity and the associated non-communicable diseases contribute significantly to the disease burden in Tanzania. Obesity can be attributed to the consumption of Sugar Sweetened Beverages (SSB) due to their high sugar content that leads to high caloric intakes. This study estimates the effect of SSB tax on the prevalence of obesity.

AbstractReducing the use of chemical pesticide while preserving crop yield is a practical strategy that makes agricultural production economically, socially and environmentally sustainable. Although the adoption of green pest control practices can help achieve such a goal, its adoption rate remains quite low. This study explores whether membership in agricultural cooperatives improves smallholder farmers' adoption of green pest control practices, utilising farm‐level data surveyed from rice farmers in China.
