“…The agro-ecological models examine changes in agro-ecological zones and crops as the climate changes. This analytical technique make use of well-calibrated crop models from carefully controlled experiments in which crops are grown in field or laboratory settings that simulate different climates and levels of carbon dioxide (Adams et al 1989(Adams et al , 1990(Adams et al , 1993(Adams et al , 1999Easterling et al 1993;Kaiser et al 1993;Rosenzweig & Parry 1994;Parry et al 1999Parry et al , 2004Kumar & Parikh 2001). To ensure that all different outcomes across experimental conditions can be assigned to the variables that are being investigated (temperature, precipitation or carbon dioxide), no variability is allowed in farming methods.…”

This study uses the Ricardian approach to examine the economic impact of climate change on agriculture in Zimbabwe. Net farm revenue is regressed against various climate, soil, hydrological and socio-economic variables to help determine the factors that influence variability in net farm revenues. The study is based on data from a survey of 700 smallholder farming households interviewed across the country.The empirical results show that climatic variables (temperature and precipitation) have significant effects on net farm revenues in Zimbabwe. In addition to the analysis of all farms, the study also analyzes the effects on dryland farms and farms with irrigation. The analysis indicates that net farm revenues are affected negatively by increases in temperature and positively by increases in precipitation. The results from sensitivity analysis suggest that agricultural production in Zimbabwe's smallholder farming system is significantly constrained by climatic factors (high temperature and low rainfall). The elasticity results show that the changes in net revenue are high for dryland farming compared to farms with irrigation. The results show that farms with irrigation are more resistant This paper-a product of the Sustainable Rural and Urban Development Team, Development Research Group-is part of a larger effort in the group to mainstream climate change research.

An important policy message from the empirical findings is that there is a need to provide adequate extension information services to ensure that farmers receive up-to-date information about rainfall patterns in the forthcoming season so that they make well-informed decisions on their planting dates. Policies that increase farmer training and access to credit and aid facilities and help farmers acquire livestock and other important farm assets can help improve net farm performance. Ensuring the availability and accessibility of fertilizers and crop seeds before the onset of the next cropping season can also significantly improve net farm performance across households. rtmano@mweb.co.zw nhemachenacharles@yahoo.co.uk This paper was funded by the GEF and the World Bank.

This paper explores how Latin American livestock farmers adapt to climate by switching species. We develop a multinomial choice model of farmer's choice of livestock species.Estimating the models across over 1200 livestock farmers in seven countries, we find that both temperature and precipitation affects the species Latin American farmers choose. We then use this model to predict how future climate scenarios would affect species choice.Global warming will cause farmers to switch to beef cattle at the expense of dairy cattle.

“…For these kinds of analyses, several authors have used more economic-based approaches, allowing for qualitative-quantitative assessments of higher levels of adaptation potentials, albeit with less agronomic detail (e.g., Polsky 2004; Adams et al 1999;Easterling et al 1993;Mendelsohn et al 1994). These studies tend to indicate small overall positive impacts for global agricultural economic indicators across scenarios and models in the first half of this century, for climate changes at the global scale of up to about 38C, and negative impacts above that degree of warming (see e.g., Hitz and Smith 2004).…”
