agro-ecological zoning is one of the effective tools for assining land to suitable land use.the study areawith16618ha islocatedin abyek area inqazvin province. in totally 43 agro- ecoloical zones were distinguished by combining maps of isohyet, isotherm, length of growing periodand agro-edaphic zones. based on above information a land suitability was produced for the study area and prediction o...

For the successful tree establishment, an evaluation of land suitability is necessary.In this paper, we demonstrate how to implement fuzzy classification of land suitability in aGIS environment for afforestation with Juglans regia in Gharnaveh Watershed of GolestanProvince in Iran. Juglans regia is one of the most important agro-forestry species in manyrural parts of Iran. Relevant criteria for...

European farming is dealing with global questions as food safety, climate change and energy, while attempting to sustain competitiveness in world markets, higher standards of food production and responding to new demands for public goods and services. The energy requirements of food production are here a central issue. But a literature review on this topic, centered in the Mediterranean, reveal...

Anthropogenic impacts increasingly drive ecological and evolutionary processes at many spatio-temporal scales, demanding greater capacity to predict and manage their consequences. This is particularly true for agro-ecosystems, which not only comprise a significant proportion of land use, but which also involve conflicting imperatives to expand or intensify production while simultaneously reduci...

For spatial decision support and regional (agro-)ecosystem modeling, land use data are of central importance and have to be available in a spatial data infrastructure for regional modeling. Usually, land use data are available, but they lack the desired information detail for many purposes. For example, in official land use maps, agricultural land use is generally differentiated between arable ...

The precipitation climatology and the underlying climate mechanisms of the eastern Mediterranean, West Asia, and the Indian subcontinent are reviewed, with emphasis on upper and middle tropospheric flow in the subtropics and its steering of precipitation. Holocene climate change of the region is summarized from proxy records. The Indian monsoon weakened during the Holocene over its northernmost...

Irrigation in the Mediterranean is of vital importance for food security, employment and economic development. This study systematically assesses how climate change and increases in atmospheric CO2 concentrations may affect irrigation requirements in the Mediterranean region by 2080–2090. Future demographic change and technological improvements in irrigation systems are taken into account, as i...

The development of a third world country requires a conscious balance between different planning and policy issues, such as population growth rate, gross national income, self-reliance and long-term sustainable ecological development. This paper reports on a cross-disciplinary project to design a decision support system (DSS) that aims to assist government policy makers in planning the regional...
