The productivity of different lettuce groups and roquette was evaluated when sown in two different periods and cultivated either singly or intercropped. Theses experiments were carried out in Jaboticabal, São Paulo State, Brazil. The first growing period was from May to August (Autumn-Winter) and the second from September to November (Spring) of 2001. The experimental design was a randomized complete block with four replications. The treatments consisted of the combination of the following factors levels: lettuce groups (crisp, cv. Vera; looseleaf, cv. Elisa; and crisphead lettuce, cv.

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.

The combination of rice and fish production into one system is considered to be an efficient means of agricultural land use for small-scale farmers. In some of these so-called rice-fish systems rice and fish are grown in the same field, at the same time; in other systems they are grown in the same field, but in rotation. Rice-fish farmers pay most attention to the maximization of the rice yield. This is a logical choice because the rice field is not the most ideal environment for fish production as the rice crop shades the field floodwater, thus hampering aquatic primary production.

Nineteen microsatellite markers were used to fingerprint a set of 19 potato landraces from the island of La Palma (Canary Islands). These landraces represent relicts of early introductions from South America, although most are commonly cultivated by local farmers. The SSR primers detected 62 polymorphisms, 13 of which were present in all landraces. Several accession- and group-specific markers were detected. Jaccard similarity coefficients were estimated from the molecular data and UPGMA cluster analysis was performed. Some cultivars with related common names clustered together.

This paper analyses the impact of the Common Agricultural Policy (CAP) and macroeconomy on land use changes in the EU. Three scenarios are simulated up to 2030: baseline, macro scenario and policy scenario. Simulation results indicate that GDP leads to a stronger effect on land use changes than the CAP. Stronger changes in land use are observed at the crop disaggregated level than at the aggregated level for the total agricultural area, arable land, grassland and permanent crops.

The effects of subsidies on the development of organic farming (OF) in the Czech Republic and in some selected EU countries are analysed in this article. The level of subsidies for OF in the Czech Republic is continuously increasing. In 1998, the total amount of subsidies was 48 million CZK, whereas in 2004, it increased to nearly 277 million CZK. The increase of subsidies led to an increase in the number of organic farms as well as the area under OF.

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.
