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 new method for analysing environmental efficiency, based on the materials balance, is proposed. With this method, an environmental allocative efficiency measure can be defined analogously to the more commonly used economic allocative efficiency. Nutrient surplus in pig fattening, a typical balance indicator, is used to illustrate the concept in a two input - one output case. The materials balance based efficiency analysis is elaborated using data envelopment analysis (DEA). Results are compared with those of more common, merely input or output oriented DEA approaches. A main conclusion is that, ignoring the balance feature of environmental issues such as nutrient surplus might be a main reason why traditional integral analyses of economic and environmental efficiency yield contradictory conclusions.

Is it feasible to increase income and generate employment in the context of a traditional labour intensive rural industry with strong linkages to an agriculturally backward economy? In order to address this issue, primary data from four villages of Peruvian North Sierra was used. The case of the hat making activity, employing exclusively family labour, purchasing the main input (straw, paja de palma) from Ecuador, and with consumers concentrated on villages and small towns, was investigated. The analysis was made at the market level. Considering the context of a self-employment activity, a theoretical framework was developed to explain the determinants of labour demand, input demand, hat output and labour return. Demand and supply constraints to the expansion of hat making activity were found. Important differences in the value of labour marginal product across the sample were identified. These were mainly associated with the use of varied input quality. Growth based on local demand would not be viable given falls in consumer incomes - mainly farmers - and expected changes in consumer preferences; therefore the growth motor would rest more in market expansion and product diversification to urban consumers.

Sustainable agriculture implies the exploitation of natural resources now, without compromising the natural resources stocks for the future generations. In the context of the paper, agricultural sustainability takes place at the interface between agriculture and the environment. The focus is on the interplay between farming systems and agrienvironmental policies. Agricultural policies have major impacts on soil and water quality and on bio-diversity. Support commodity price policies have lead to serious problems of water pollution; high levels of soil erosion; nitrate losses and lost of biodiversity. The semi decoupeted income support policies and the introduction of the agrienvironmental schemes under the 1992 CAP reform were the first attempts to correct the negative aspects of the production-orientated policies. For the first time farmers were regarded as countryside and landscape keepers and as environmental conservationists. Under the 2000 Agenda similar emphasis was given to the sustainability of agriculture. The objective of this paper is to evaluate the impact of the different agri-environmental policies on typical farming systems and consequently their effects on water pollution, soil erosion and bio-diversity/landscape. A bio-economic model, integrating a mathematical programming model and crop growth simulation model, is applied to estimated the changes in the levels of nitrogen leaching and soil erosion, and in the degree of bio-diversity under the current and proposed agricultural policy scenarios. The following farming systems are studied: dry land cereal farming systems (intensive and extensive), livestock and irrigated farming systems using conventional and conservation farming technologies. The results show The results show that the main changes on water pollution, soil erosion levels and biodiversity are mainly due to changes in price and arable compensatory payments. The agri-environmental measures are more important as farm income source than as a policy instrument to influence environmental parameters.
