In most mammalian species, body mass is one of the key factors affecting an individual's fitness. It is therefore important to know the causes of its variability. The present paper analyses the influences of habitat structure and other environmental factors on body mass in red deer. The research is based on data sets concerning 3,920 culled red deer from the entire Slovenia, which are geo-referenced within a kilometer spatial accuracy, and on 28 spatially explicit raster layers of population density, habitat structure variables (e.g.

Soil erosion supplies large quantities of sediments to rivers of Southeastern Asia. It reduces soil fertility of agro-ecosystems located on hillslopes, and it degrades, downstream, water resource quality and leads to the siltation of reservoirs. An increase in the surface area covered with commercial perennial monocultures such as teak plantations is currently observed at the expanse of traditional slash-andburn cultivation systems in steep montane environments of these regions.

The agricultural lands have a special legal regime and are subject to the protection aimed at limiting the seizure of these lands, preserving and increasing their fertility. The area of lands of this category in the structure of land Fund accounts for 100.8 million hа, or 38.6% of used land. Their share in the land Fund of the regions ranges from 70-75% (North-Kazakhstan, Akmola region) to 10-20% (Kyzylorda, Atyrau region). It is mainly related to different climatic conditions and vast areas of desert and semi-desert rangelands.

This paper aims to contribute further research on the conceptualization of agricultural multifunctionality through quantitative methods. The empirical analysis is based on a large dataset (Agrobarometre of Andalusia) consisting of self-reported measures of individual opinions on multifunctionality. Ordered probit models are proposed to analyze the extent to which individuals' perceptions of multifunctionality can be explained not only by individual and regional characteristics, but more importantly, by the preferences individuals have for a given type of agriculture.

We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd. We illustrate these packages with examples extracted from the various models. The role of this tool is discussed in order to show its advantages and its limits
