    The farming system at landscapes preserving and restoring soil fertility of agricultural lands have been developed. Typification of lands was made and the types of agricultural landscapes were allocated: plain, hollow-gully, and gully-field. The analysis of the current structure of arable areas was made and resulted in the assessment of structure's influence on the state of soil fertility. The main degradation processes reducing the fertility of south chernozems were studied. There were proposed the ways of creating the sustainable artificial agricultural landscapes.

    Life Cycle Assessment (LCA) is a robust tool often used for eco-design. It allows the assessment of environmental impacts, at a global scale, accounting for all stage of a product life cycle, “from cradle to grave”. There is a methodological gap in this method to account for occupation and transformation impacts in marine ecosystems due to human activities. The task accomplished during this PhD is the development of a methodological framework for a new impact category in LCA to overcome this lack: the sea use. The general framework for sea use had to be defined.

    The presence of trees in the farms is typically considered a good practice in water shed  management. Therefore, it was examined the voluntary adoption of land uses considered more compatible with the water ecosystem service (shade coffee and woodland) in the region of Trifinio (located in Honduras and Guatemala), where there is not given any incentives or payment for this environmental service. It was observed low adoption of these land uses on small farms.

    Research on the sustainable use of the soil as the main agricultural resource employing different field crop rotations and tillage systems was started in 2009. The influence of new technologies on sustainable output of agricultural raw materials used for safe and good quality food and feed production was studied at the Latvia University of Agriculture, Study and Research Farm “Peterlauki” where long-term field experimental plots were established specially for this purpose. Complex investigation of the soils at the experimental plots was performed.

    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.

    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.

    This study aims to clarify the features of community plans based on the 'Rural Rejuvenation Act'(RRA), choosing Miaoli county of Taiwan as a case study area. We scrutinized planning documents made by national and county government and conducted interview to government officials who take charge in Rural Rejuvenation. As a result, we clarified two features: 1) the form of planning document is developed by the government but contents are different from community to community, combining various hard and soft programs to deal with varying characteristics of local communities.

    Coping with water scarcity and growing competition for water among different sectors requires proper water management strategies and decision processes. A prerequisite is a clear understanding of the basin hydrological processes, manageable and unmanageable water flows, the interaction with land use and opportunities to mitigate the negative effects and increase the benefits of water depletion on society. Currently, water professionals do not have a common framework that links depletion to user groups of water and their benefits.
