Determinants of Climate Change Risk Management Strategies Among the Aquaculture Fish Farmers in Nigeria Using Multinomial Logit Model

Nigeria’s domestic supply of fishery products falls short of the demand; however, there is a growing aquaculture industry that has come to the rescue in filling the gap between supply and demand. The aquaculture fish farmers are prone to the risk of climate change, since weather and extreme events have become more unpredictable. This study assessed the climate change risk management strategies among the aquaculture fish farmers’ in Southwest Nigeria. Multi-stage sampling technique was used to select 480 aquaculture fish farmers’ in the study area. Descriptive statistics, likert scale and multinomial logit model were used to analyze the data. The study revealed that all the respondents were aware that climate is changing. The commonly used adaptation strategy by the fish farmers in the area was use of concrete /plastic pond (78%). The result of the multinomial logit model revealed that farm income influences the adoption of flood control/provision of water outlet by 19.22%, provision of alternative water supply (Well/Borehole) by 45.11% and the use of the concrete/plastic pond by 18.89%. Flood control/provision of water outlet, providing alternative water supply (Well/Borehole), use of concrete /plastic pond are all investment that were positively significant at 1%. Therefore, increase in farm income will lead to increase in these adaptation strategies to mitigate the effects of climate change on fish production in the study area. The study recommends that government at all levels should provide loan at a single digit interest rate to mitigate the effects of climate change on aquaculture fish farming.

Determinants of Household Demand for Fresh Fruit and Vegetable in Nigeria: A Double Hurdle Approach

The study investigates separately demand characteristics of consuming healthy food such as fresh fruit and vegetable (FV) based on the 2003/2004 Nigeria Living Standard Survey (NLSS) data. It uses the double-hurdle model that allows the analysis of both the decisions to consume and the demand for FV to differ. The empirical results show that an average household in the sample considered the demand for FV to be luxury good. But a closer look at the results across income groups show that households in the low and high-income groups considered the demand for fresh fruit to be necessity and luxury goods, respectively, while all households irrespective of which income groups they belong considered the demand for fresh vegetable to be luxury good in the study. Our results also imply that the demand for FV is higher among households with younger members, compared to households with older members. Regional differences in the demand for FV are also evident in the study
