Current levels of nitrogen deposition, especially ammonia, seriously impact upon ecosystems biological diversity. However, land use policy maintaining and enhancing key ecosystems in the UK in most cases does not explicitly take account of this pollution in terms of onsite management prescriptions. In this paper the economic potential of agricultural land retirement to reduce localised nitrogen...

Land-use-change patterns are the result of the complex interaction between the human and the physical environment. Case studies of the determinants of land-use change can help to analyse which theory is appropriate in a particular region and stimulate the development of new theoretic understandings. In this paper an empirical method is presented to analyse the pattern of land-use change that al...

Human use of land has transformed ecosystem pattern and process across most of the terrestrial biosphere, a global change often described as historically recent and potentially catastrophic for both humanity and the biosphere. Interdisciplinary paleoecological, archaeological, and historical studies challenge this view, indicating that land use has been extensive and sustained for millennia in ...

Aim We used the extensive climatic and land-use gradient on Mt Kilimanjaro, Tanzania, to study large-scale variation of nutrient use in ground-foraging ant communities. In particular, we tested the hypothesis that recruitment of ants to six different nutrients would vary with elevation and between land-use regimes. We also tested whether the nutrient space (number and evenness of nutrients) use...

planners have regarded understanding urban use per capita since the beginning of new thinking of urban development. this was stared with its pragmatics toward primary comprehensive urban plans and became a source for urban development plans that have tried to adapt per capita and standards with country’s conditions. iran's supreme council for planning and architecture, determined standards...

soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure.so, this research has been done for achieving this purpose. this area is arounding sa...

land use planning, refers to how to use, distribute and protect the land. this type of planning can be considered from different perspectives, such as sustainable development perspective view is one of important land use views. in this paper we have tried to study and evaluate the land use change of maragheh city from sustainable development perspective, and study the harmony or disharmony with...
