    Agricultural land use does not only concern farmers, but also has a large number of social and environmental effects. Consequently, it is to be assumed that farmers have to use financial resources as well as labour in order to provide these services. Using the nonparametric method of Data Envelopment Analysis (DEA), we calculated the economic as well as the ecological efficiencies of farms and examined whether farms are able to succeed in combining ecological and economic efficiency. In addition to this analysis, we studied the driving factors of the respective efficiencies.

    In Italy, the structure of farm has always shown remarkable elements of weakness. Among these, the small dimension, in terms of arable land, has represented one of the most difficult to resolve. The absence of a legislation that could favour jointness of the property have remarkably reduced the market of the land. In this scenario, a new law n. 203/1982 was lunched. Now farmers are considering rent land a possible strategy to increase hectares. The object of this paper is to analyse the situation of land contract in Campania Region.

    Econometric and simulation analyses indicate that land degradation does not threaten agricultural productivity growth and food security at the global level, but problems exist in some areas. Improving market performance could reduce erosion-induced yield losses to 0.1 percent per year and the number of hungry people in less-developed countries by 5 percent over 10 years.

    We describe a landscape scale non-linear discrete choice spatial optimisation model for identifying cost-effective strategies for achieving environmental goals. Spatial heterogeneity and configuration issues such as fencing costs, patch sizes and network linkages are explicitly accounted for and quasi-optimal allocations are determined using simulated annealing. Applications of the model being developed with New South Wales Catchment Management Authorities are discussed.
