      abstract = {This study investigated the extent to which climate  variability (proxied by rainfall variability) and  macroeconomic policies influenced food crop output in  Nigeria. It used time series data obtained from Central  Bank of Nigeria and National Bureau of Statistics  (1978-2009). Four functional forms of OLS models were  tried. The Cobb-Douglas function was finally adopted based  on standard econometric model selection criteria and  diagnosis. Chow test was used to test the hypotheses of the  study. It was found that rainfall variability influenced  crop output negatively. Climatic factor, loans guaranteed  by Agricultural Credit Guarantee Scheme Fund and lending  rate were all statistically significant drivers of crop  output in the economy at p<0.05, p<0.01 and p<0.05  respectively. Their elasticities were respectively 4.01%,  0.52% and 0.98%. No structural difference between the  economic reform era and the preceding era‟s regression  coefficients was found. Programmes to stem corruption and  loan diversion; subsidization of agricultural credit and  climate change adaptation capacity building programmes were  recommended to bring about sustainable food security in the  country.},
