    In this paper we study the interplay between residential location choice, sprawl and water quality. We propose an urban economics model of a, first, monocentric, then, polycentric city with two di erent residential areas : sewer-serviced suburbia, with small residential lot size, and exurbia where wastewater management is individual and on-site and residential lots are larger to accomodate sanitary requirements. Sewer and septic are also characterized by di erent abatement e ciencies.

    This study was done to establish relationships between management and sanitary practices on ewe dairy farms and the quality of milk produced. For this purpose, a survey was carried out on 118 farms and a total of 121,117 animals in the Castilla-La Mancha region (Southeast Spain) in which the veterinarians of the Association of Sanitary Defence participated. Flocks varied considerably in size, ranging from 120-7,200 sheep, with an average milking period lasting 3-5 months and milk yields of between 50 and 150 litres per lactation by mechanical systems on 75.0% of farms.

    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 purpose of this study was to explore the characteristic of structure, species composition and species diversity in secondary mixed deciduous forest at Thung Salaeng Luang National Park, Lower North of Thailand. This vertical stratification of the tree canopy can affect the growth of young trees on the ground surface, especially that of saplings and seedlings. Ground species can establish themselves very quickly when the light intensity is high enough and especially when the light can penetrate directly to the ground during gap formation.
