How Does Climate Change Affect Tomato and Okra Production? Evidence from Nigeria.

This study examined the impacts of climate change on okra and tomato yields. Fertilizer consumption and credit to the crop sector were considered as covariates in the analysis. Time-series data, spanning a period of 40 years, were obtained from various sources. An autoregressive distributed lag model was applied to analyze short- and long-term impacts of climate change and agricultural inputs on okra and tomato yields. Not all variables were stationary at levels (order zero), but they were all significant at first difference, indicating the presence of cointegration. The Bound's test F-ratio was statistically significant and implied the presence of long- and short-term relationships among the variables studied. The mean temperatures had negative impacts on okra and tomato yields in both the short and long terms. Credit guaranteed to the crop sector had positive short- and long-term impacts on tomato yield; fertilizer consumption had a negative long-term impact on okra yield. Our study concludes that climate change, particularly rising temperature, impacts herbaceous fruit crop production in Nigeria. Therefore, we recommend that breeding and disseminating climate-smart tomato and okra varieties will help fruit crop farmers respond to rising temperatures.

Sustainable cereal production: A spatial analytical approach using the Ghana living standards survey.

Ghana as one of the countries south of the Sahara, depends solely on cereals as a major staple food. Ironically, Ghana's economy depends on large importation from the global north, particularly Asia, due to systemic production deficits. The probability of farming households producing enough cereals and the constraints to meeting domestic supply remains imperative. Therefore, the current research focussed on the Ghana Living Standard Survey seventh round (GLSS7) involving 15,045 cereal farmers nationwide. By estimating the probability of farming households producing cereals and the factors that constrain cereal production. Using random-effects regression models, the empirics show that farming households are expected to produce 5.87 tonnes of cereals annually. Specifically, farming households headed by males are expected to produce 6.01 tonnes of cereal crops in a year, 0.14 tonnes more than female-headed households. Non-poor households are expected to produce 6.82 tonnes of cereals in a year compared with an expected production of 6.29 tonnes by poor households. Cereal production is constrained by wealth status, gender, and age of household heads. Our findings attempt to inform and shape policy towards sustained cereal production in Ghana, and by implication countries in sub-Saharan Africa (SSA). The Ministry of Food and Agriculture (MoFA) in Ghana, should bring on board a structural policy that will address constraints related to gender, wealth, and age of household heads to enhance sustainable cereal production.
