... of farms, which discriminate different levels of social and environmental vulnerability. Four production functions are modeled (milk, cattle, goat and sheep) accounting for sample selectivity bias. Findings In response to increasing temperatures, farmers tend to shift their activities mainly to cattle...

.... Design/methodology/approach The study used a production function model using Fixed Effect Regression (FER) analysis and then using marginal impact analysis to assess the impact of climate change and variability on agricultural production. Therefore, the study utilized panel data for the period 1961-2009...

.... The author found from the stochastic frontier estimation in the production function that climate change adaptations exerted a significant impact on farm productivity. It helped in coping with the adverse effects and risk of climate change while increasing agricultural productivities of the farmer-respondents...
