1/100 000 scaled Environmental Management Plan of Istanbul Province has planned to use the green belt of Istanbul for agricultural purposes. One of the most important factors for the agricultural planning process is the protection of the water basins in Istanbul towards the fertilisers and pesticides pollutions. There are, in addition, other important factors influencing the agricultural planning which are providing rural development, prevention of land misuse and protection of biodiversity. One of the most appropriate approaches to perform these aims is organic farming. This study is a side project of the 1/100 000 scaled Environmental Management Plan of Istanbul Province and aimed at determining and mapping the potential organic farming areas in Istanbul. The study consists of 2 phases. First phase is synthesising the parameters of meteorological, topographic, agricultural, soil and forestry database, water basins, settlement, industrial, mining and waste disposal areas and transportation network. Multi-Criteria Suitability Analysis for organic farming areas by these parameters was determined through the quarries in Geographic Information System (GIS) environment. In the second phase the field surveys were submitted including soil and land survey in the rural areas about 253 000 ha and conducted polls in the rural settlements. The potential organic farming areas were determined and classified into 3 groups according to its priority degree. The results indicated that the potential organic farming areas in Istanbul, classified as first, second and third priority, covered, respectively, the surface area of 27 060, 5183 and 415 ha. which could promote the organic agricultural production.

Providing the sustainable use of natural resources is very important while determining the urban planning and developing strategies. Also another important subject in terms of urban planning process is the identifying the limiting factors that affect urban settlement negatively. Therefore, the determination of the ecological thresholds is one of the most significant factors that must be taken into consideration while urban land use planning. Edirne which is the most western province in Turkey has a rich inventory of natural resources within its wetlands, productive agricultural areas and forest areas. In addition to ecological riches there are also inconvenient areas in terms of urban settlement in Edirne like flood plains, dunes, etc. This study aimed at the subjects of analysis of natural resources inventory and determining the ecological thresholds in the Edirne province by means of parameters like terrain properties, agricultural and soil resources, forest areas, wetlands, surface and groundwater resources, protected areas and geological risky areas. The digital data of the parameters were stored in a geographic information system (GIS) database and made suitable for spatial analysis. The specialist opinions were taken into consideration for determining the thresholds of the parameters. To determine the ecological thresholds from these multi-parameters it was used that the analytic hierarchy process (AHP) which is a multi-criteria decision analysis method. The results of the AHP were applied within GIS environment and an ecological thresholds map of the Edirne province was created for urban land use planning. Source

For the protection of soil and water resources and providing the sustainable development in the Thrace region, a new model has been proposed for the best utilising the agricultural potential of the Thrace region where the cultivatable agricultural land covers about 82% of the total area. The model which has been taken into consideration in terms of rural development is based on the forming and construction of the organised agricultural zones (OAZs) and the agricultural sub-zones (ASZs) in the Thrace region. Since the development of the specialised and organised agricultural industry zones, it will be encouraged that to build new agricultural and livestock facilities will increase the potential of agricultural and livestock production in the region. Consequently, the OAZs and the ASZs will provide an increase in the agricultural labour supply and demand in the region and a decrease in the population loss in the rural areas.This proposed model has been applied within the 1/25 000 scale environmental management draft plans of three cities: Edirne, Kirklareli and Tekirdag provinces in the Thrace region.

The earth zone will come into intensive and long-term dry periods. It is essential to take precautions mainly for providing continuous food production and saving and planning water supplies against this natural disaster which impacts will rapidly increase in the near future. In this project, a model has been proposed which will provide the optimum water consumption and continuous agricultural production. The Silivri district was chosen as study area because it has got the highest agricultural potential in the province of Istanbul. All data which have been carried by 1:25 000 scaled soil map, air photos, satellite images and fieldworks are stored in a GIS database. Through the quarries in terms of topoghraphical database and physical and chemical soil characteristics, land use suitability classes (LUSC) have been determined and mapped. Further water-holding capacity of the agricultural land was determined according to the soil texture. Also the existent agricultural crops in the region and the new proposed agricultural crops, which can be able to adapt to changing conditions, have been listed. Consequently an agricultural crop pattern has been designed for the Silivri region against the drought periods by means of water-holding capacity of soil, annual water consumption of plants and LUSC.

Socio-economic and spatial development tendencies necessitate urgent, multi-dimensional and integrated measures for Istanbul, which highlight once more the importance of sustainable spatial planning for availing appropriate orientations to the human ecology and the future of mankind in general. Spatial planning could be used as an operational instrument to coordinate ecologically sound socio-economic development by aid of pro-active and preventive as well as protective approaches for natural and cultural environments. The sustainable spatial planning for Istanbul, however, requires a certain scenario based on functional continuity of the life-support systems, which are crucial for the entire metropolis and deserve to be regarded with priority in planning and management processes. In this study, the evaluation was considered as the initial step of sustainable spatial planning for the Istanbul metropolis, in which ecological belts and corridors were treated as essential macro-spatial elements. These prime elements were therefore determined as the main guides for design of the prospective metropolitan macro-form model, which would comprise local urban management issues and give projections to lower-scale planning studies from higher-scale viewpoints in hierarchically organised spatial systems.
