Background and objective: The trend of increasing urban-rural population and the effect of household competition in meeting the basic needs of life, has caused the consumption of various resources, including Miandorood Mazandaran, to accelerate growth. In such a competitive space, agricultural land resources have changed so that the scope of these human needs for resources has led to land use change and, consequently, increased erosion and decrease renewable resources in the target study area. In this regard, the records of global research related to land use change, have indicated approximately the same results of quantitative and qualitative reduction of arable soils and increased erosion of soil resources. So, the purpose of this strategic research is a sign of the trend of land use change commonly on the shortcomings of process effectveness and cause the stability of cultivated soils, the development of mutual employment and increase the productivity of agricultural systems in the Miandorod region.
Materials and Methods: Miandorood region, due to the structure of natural civilization and special agricultural area, this research study was conducted in this strategic area. The total area of this area is 483 square kilometers, of which the usable lands area is 30,335 hectares. This research, which is a descriptive-analytical study with a field (survey) approach, and its statistical society is the internal and external system components of the region (strengths-weaknesses and opportunities-threats), and information on important soil components. Hence, the model of choice for this strategic goal is (WOTS-UP Analysis) and its subsets. For analysis and conclusion, respectively; Excel program, quantitative strategic planning matrix table and Wensim intelligent program were used for decision making. And to rank the internal and external components, experience and strategic thinking and consulting with experts in the region (in a survey), was used.
Results: Due to the trend of land use change and the increase of smallholders in the region, the percentage of process effectiveness 33.97%, has shown very low. As a result, with low process effectiveness, the amount of affected components such as; Reduction in soil organic carbon content from 2.7 to 0.56, usable phosphorus content of regional soils from 56.3 to 6.4 mg / kg, absorbable potassium content from 301 to 117 mg / kg, the amount of absorbable sulfur from 29.1 to 20.5 mg / kg, increasing the pH of plain soils from 6.6 to 7.9, and increasing Gradual electrical conductivity EC, from 0.9 to 3.0, (dS / m) and finally to increase the negative physical density at a depth of 25-30 cm in the arable soils of the region over the past decade Has been.
Conclusion: The results of this study, which were accompanied by the identification of development components (strengths and opportunities), and deterrence components (weaknesses and threat points), showed that land use change in the study area on the physical and chemical properties of soils Agriculture in the Miandorood region has a negative effect. Conversely, by implementing a strategic management system (Scenario 3 selection), it is possible to be effective in arable soils sustainability, development of bilateral employment, decrease of unemployment rate, and effectiveness in arable land productivity.
