Relationships between the greenhouse effect and agricultural activity are usually and firstly considered in terms of the impact of climate change on agriculture. But in reverse, farmers and herders may react to a climate policy imposing a carbon price to GHG-emitting activities, and possibly contribute to the emissions mitigation as well as to carbon sequestration. The degree of efficiency of the reactions will vary across regions of the world and across activities. A methodology considering risk associated with technology changes is proposed for estimating and accounting these reactions under production and resource constraints. For a business-as-usual scenario quantified by the integrated assessment model Image, decisions concerning land-use and alternative practices are modeled. Results indicate that main agricultural activities provide little room for manoeuvre for emissions mitigation.

This paper examines the factors influencing farmers' participation in several agri-environmental schemes. A multinominal logit model is used to separate between participating and nonparticipating farmers. In addition this model allows to predict farmers participation in one measure as well as in different measures simultaneously. Data stems from a survey conducted in eight European countries and includes a description of both farmer and farm characteristics. Three categories of schemes have been analysed: landscape maintenance, biodiversity protection and restriction of intensive farming practices. The combination of these three types of schemes provides eight possible packages which can be selected by eligible farmers.

The multinominal logit model shows the importance of both farm and farmer as well as attitudinal characteristics on the participation in different combinations of schemes. For instance, the environmental concern favours landscape maintenance and biodiversity protection as well as their combinations with schemes requiring restrictions of intensive practices. However, it has a negative effect on the single participation in schemes requiring restrictions of intensive practices only. Our analysis confirms a number of previous findings. In addition, it shows the importance for policy makers to take into account that farmers have the opportunity to enter several schemes simultaneously. Indeed, due to cost complementarities, joint participation provides both private and public benefits.

A non-linear optimization model which maximizes total Ecuadorian social welfare, defined as the sum of Consumers’ and producers’ surpluses for the four major crops (corn, bananas, rice and African palm) is developed to evaluate the tradeoff between welfare and environmental degradation in Ecuador. It was found that a total welfare loss of US$122 million (a 11 percent reduction - from US$ 1.112 billion to US$ 989.66 million) would be expected from a 30 percent reduction in the total pesticide load on the environment in the production of the four major crops. The distributional impacts of the welfare loss were found, however, to be significantly skewed toward the loss of consumers’ surplus. Specifically, a 30 percent reduction of total pesticide load on the environment would result in a reduction of 3.86 percent of producers’ total surplus while consumers would be expected to loose 19.46 percent of their total surplus.
