Since the 1990s, the Egyptian government has embarked on two national projects on settlement and agricultural development in the Western desert in preparation for expected future population growth. One of them is the Toshka irrigation project, which carries water from Lake Nasser through the depression of El Kharga towards Farafra Oasis. Another is the East Oweinat project, which has enlarged agricultural land in the south of the Western desert by developing water resources from underground aquifers of Nubian sandstone.

In an economic analysis the present use of the most important national park in South Africa, (Kruger National Park) is compared with the use of the same land for agricultural purposes. The present use of the Kruger National Park creates substantially more net social benefits to society than agricultural use. The question remains whether these benefits are equitably distributed at various levels of the South African society.

The global carbon cycle has feedbacks on the global climate, and climate-carbon cycle interactions are explicitly represented in earth system models (ESMs). In ESMs, leaf area index (LAI) is a key variable for projecting future environmental changes, but it might be one of the most difficult to precisely predict. In this research, historical LAI changes reproduced in the ESM named 'Model for Interdisciplinary Research on Climate ESM (MIROC-ESM)' are analyzed, focusing on impacts of CO2 fertilization effects, climate change, and land-use change.

The purpose of this study is to help build a clear picture of grazing in an agriculture region of China, to find out why farmers buy supplemental feed which is used in winter when their farmland is abandoned and covered by weeds. To meet this goal, I used the case of a village where farmers not only supplied but also bought supplemental feed to see how they used farmland. I discovered the following : The land fragmentation causes them to abandon arable field and borrow farmland from others by their relationship. So they don't have enough farmland to plant feed.

For over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment. In order to better understand and follow modification processes, a comparative study of livestock systems and land dynamics has been carried out on seven case studies on three continents through the use of a common grid.

This document provides an overview on land use and spatial development in the Montpelier region and turning points the planning and governance regime. In the first part we give an overview on the land use and regional development of the case study region. In the second part, we introduce the planning system, its major actors and instruments as well as governance aspects to the reader.

The work presents a brief report of the main results of a study carried out by the Spatial Engineering Division of the Department of Agricultural Economics and Engineering of the University of Bologna, within a broader PRIN 2005 research project concerning landscape and economic analysis, planning and programming. In particular, the study focuses on the design of spatial analysis methods aimed at building knowledge frameworks of the various natural and anthropic resources of rural areas.
