Présentation

In the turmoil of a rapidly changing economy the Mongolian government needs accurate and timely information for management of their natural resources and formulation of agricultural land-use policies. Agriculture is one of the most important sectors of the Mongolian economy, as it is the major source of employment and the main land and water user. Mongolia began to cultivate virgin lands at the end of the 1950, 1976 and 2009 years. From 1990s, Mongolia entered a period of transition from a central-based planned economy to a market economy. The change to a market-oriented economy had also an impact on the natural resources and their management, not only due to privatizations, but also because of the strong land fragmentation as a result of the land distribution and increased urbanization. Mongolia’s transition experience since 1991 has been positive, but difficult. Privatization is considered essential to the process of reform for three main reasons : in first, to establish well-functioning markets, secondly to create incentives for decision makers to act in response to market signals, and third one is to assure irreversibility of the reforms themselves.

Agricultural sustainability has the highest priority in all countries, whether developed or developing. The discussion about development of the agricultural sector has often centered on the question of how to achieve adequate food security, while simultaneously providing sufficient income for food producers. Agricultural sector development is strongly related to land use. The way land is used has obvious implications for food security, economic development and the environment. Increasing the level of self-sufficiency in the production of strategic crops (e.g., wheat, barley, potato and vegetables) is one of the objectives of Mongolian policy makers. Currently, Mongolia is importing a significant part of its national requirements for these crops. For economic and social reasons, increasing national production and the level of self-sufficiency is urgently needed. Therefore there is need to develop mapping and monitoring cropland area in Mongolia.

The main objectives of this study are ; 4- to provide a recent perspective for cropland cover changes that have taken place between 1989 and 2000 and to examine the capabilities of integrating remote sensing and GIS in studying the spatial distribution of different cropland cover changes 5- to introduce precision farmland technology and to develop cropland information system in Mongolia 6- to investigate a crop stress index in wheat planting area using remote sensing techniques.
