The special issue focused on topics in environmental and resource economics that originated from the inaugural conference of the African Association of Environmental and Resource Economists (AFAERE), held on 2-4 August 2021.
Climate change and its pronounced effects have greatly disfranchised the livelihoods of aquafarmers. To leverage these negative effects of climate change, climate-smart aquaculture (CSA) practices have been developed for adoption by farmers. However, it is not known whether these practices have made any meaningful contribution to farmers in terms of their livelihoods and resilience to the vagaries of climatic change.
Soil acidity is a major constraint to crop production in tropical regions. Although agricultural lime is one option to remediate acid soils, there is limited information on the potential returns on investments to liming by smallholders.
This study applied stochastic frontier analysis (SFA) and data envelopment analysis (DEA) to examine the technical efficiency of maize production in northern Ghana using cross-sectional data from 360 maize farmers for the 2011/2012 cropping season.
Sub-Saharan African countries, with their initially large agricultural sectors, reduce poverty and urbanise most rapidly and efficiently when they achieve rapid agricultural growth.2 The faster agriculture grows, the faster its relative importance declines.
While a large body of literature documents the existence of informal arrangements to share risk across and within households, there has been little research on the various coping strategies through which risk sharing takes place, and how these strategies function.
This study empirically investigates the effect of the productive safety net programme (PSNP) on household food consumption and dietary diversity in Ethiopia. The study applied random effects with instrumental variables to estimate the effect of PSNP membership.
This study examines how food prices and related seasonality factors affect the dietary choices of low-income farm households in rural Tanzania. The Kishapu and Mvomero districts were selected based on contrasting rainfall patterns, farming practices and economic activities.
This paper contributes to the expanding literature on multidimensional poverty and gender inequality in Tunisia by presenting an individual measure of multidimensional poverty.
Many governments adopt agricultural policies that affect production incentives across commodities. In addition, severe market failures in the form of high marketing margins often lower the prices that farmers receive.
This study investigates the driving factors that influence farmers’ decisions to adopt modern agricultural inputs (MAI) and how this affects farm household welfare in rural Rwanda. To account for heterogeneity in the MAI adoption decision and unobservable farm and household attributes, we estimate an endogenous switching regression (ESR) model.
This study examines the complementarity and substitutability effect of private investment and public expenditure on agricultural productivity in Nigeria for the period 1978 to 2018. The study employs the vector error correction modelling (VECM) technique, and the estimate shows that government expenditure on the agricultural sector had the most significant effect on agricultural productivity, followed by commercial bank credit for the agricultural sector.
Low agricultural commercialisation due to low productivity and a lack of access to and use of improved seeds are common features of smallholders in the Ethiopian highlands. Seed-producer cooperatives (SPCs) were established and strengthened in these highlands to facilitate smallholders’ access to improved seed.
This study characterises the nature of the vegetable production shortfall throughout Ghana for remedial action to be taken. By applying the meta-stochastic frontier analysis to a sample of okra, pepper and tomato farmers, the results show that the ranking of production inputs in production is in the order land, hired labour, fertiliser, pesticide and family labour.
Agricultural price transmission across space and time: The case of cowpea and yam markets in Nigeria
The transmission of price changes to markets has attracted renewed interest since the international food price spikes of 2007 to 2011. In response to this, this paper investigates the long-run behaviour of Nigerian cowpeas and yam tuber retail prices across space and time from 2000 to 2015.
This study examines the impact of remoteness on productivity growth among Malawian smallholder farmers.
The determinants of the technical efficiency (TE) of adopters and non-adopters of soil and water conservation (SWC) technologies in the upper Rwizi micro-catchment of south-western Uganda are compared using cross-sectional survey data from 246 smallholder farmers.
This study attempted to identify determinants of farmers’ maximum willingness to pay (WTP) for improved use of irrigation water.
In this paper, we establish a link between crop productivity, crop market participation and agricultural technology use among smallholder farmers.
Conservation agriculture is promoted as a green technology that enhances the productivity and food security of farmers. However, there is limited evidence from practising farmers regarding these expected outcomes.
We look at the prioritisation of agricultural value chains (VCs) for the allocation of R&D resources that maximise development outcomes (poverty, growth, jobs and diets) in Senegal.
We measured the producer price impacts of food and cash transfer programmes in Ethiopia using monthly panel data from 37 zones in four major regions over the period January 2007 to December 2010.
This study ascertained the influence of farmers’ perceptions of climate change effects and their household characteristics on the choice of adaptation technologies they adopt. The survey relied mainly on institutional and primary data for its analysis.
Integrated pest management (IPM) has been promoted globally as an alternative approach to the widespread broad-spectrum chemical insecticidal application for the control of pests and diseases in agricultural production to minimise the harmful effects of the chemicals on humans and the environment.
