Climate change will have a permanent impact over Mesoamerican agricultural sector. Present day crops such as coffee may not be enough to secure agricultural subsistence levels, therefore, the first stages of crop diversification are being observed in countries such as Nicaragua. Implementation of new crops such as cocoa may lead to new impacts over the environmental structure of the Mesoamerican ecosystem. These impacts may be of different, nature, but being diversification an already undergoing process attention must be paid to the underlying motivation and decision-making processes involved. This study analyses subjacent motivations and contexts that lead to the potential incorporation of cocoa crops in present-day Nicaraguan coffee farms. In order to achieve that, three main motivations were identified: climatic, economic and governmental. An econometric analyse was performed over the variables that affect farmers? motivations and decisions, in order first to analyse this decision-making process, and second, to understand how social and climatic evolution over the next decades will impact the context under which agricultural output is shaped. It was found that climatic perspectives are most closely affecting the smallholders? decision of incorporating cocoa plantations into their farms. Therefore, climate change will most certainly have a major role in the reshaping of agricultural structure in most of Nicaraguan geography. Moreover, results show a lower impact of market conditions and public subsidies over farmers? choices and decisions. These results favour the intuition that risk-reduction is a preferred strategy among Nicaraguan smallholders.

Among the challenges facing the European Union agricultural sector in the coming years, the impacts of climate change could lead to much greater variability in farmers? incomes. In this context, the insurance industry will have to develop new instruments to cover farmers? incomes against losses due to meteorological factors. Some protective technologies that farmers can use for climate risk management have associated costs that vary as a function of the losses involved. These sorts of instruments compete with other less flexible instruments such as crop insurance. We here analyse an issue of decision-making, where the farmer can decide how much to invest in protection, as in situations where the farmer chooses which portion of a loss to protect in the case of adverse weather conditions, and we propose optimal management to mitigate the increasing negative effects of climate uncertainty. By analysing the optimal policy in a continuous choice situation, we consider whether farmers, as part of their crop management duties, should opt to protect some portion of their harvest value with available technologies, or whether they should protect the entire crop. To analyse this decision-making problem, we employ the cost-loss ratio model and take risk aversion into account.

Coffee producers in Mesoamerica are already facing some of the expected challenges arising from pressures derived by climate change, principally lowered water supply. Some farmers have implemented strategies of adaptation based on crop diversification, being the introduction of cocoa one of the main alternatives. The focus of this research is to analyse coffee producers’ perceptions on changing from coffee to cocoa as an adaptation strategy. This research tries to find the factors that smallholders take into account when facing the decision of introducing cocoa. Here we simulate the farmers’ response to climate factors and water needs, also considering its relationship with humankind, specially through variables related to economic and social development. Farmers’ perceptions were extracted via a specifically designed questionnaire applied to 219 small coffee producers in the departments of Esteli and Jinotega in Nicaragua. A Multivariate probit econometric model was estimated to analyse diversification through three simultaneous equations—for climatic, economic and social development drivers.  Marginal effects of these drivers were calculated and used to simulate farmers’ response to global change scenarios. Regional distribution of crop diversification probability was mapped considering different global change scenarios. The importance of climatic factors over the decision process is, as data shows, higher than social and economic issues. The environmental implications of this change, such as deforestation, have also been discussed.

The coming agenda for the European Common Agricultural Policy includes more incentives for the environmental compliance of farmer’s activities. This will be particularly important in the case of water risk management in Mediterranean countries. Among the new challenges is the need to evaluate some of the instruments necessary to comply with the Water Framework Directive requirements that emphasize the management of water demand to achieve the environmental targets. Here we analyze the implications of changing water rights as a policy response to these challenges. We analyze two important aspects of the decision: (i) the effects on the crop productivity and efficiency and (ii) the effects on the rural income distribution. We provide the empirical estimations for the marginal effects on the two considered aspects. First, we calculate a stochastic frontier production function for five representative crops using historical data to estimate technical efficiency. Second, we use a decomposition of the Gini coefficient to estimate the impact of irrigation rights changes on yield disparity. In our estimates, we consider both bio-physical and socio-economic aspects to conclude that there are long term implications on both efficiency and social disparities. We find disparities in the adaptation strategies depending on the crop and the region analyzed.
