today, in the countries of the world, the population in urban areas is increasing rapidly. In order to avoid adverse socio-economic and environmental impacts, rapid urban growth should be managed and planned in an appropriate manner. In order to plan and manage this phenomenon, spatial data related to the pattern and the growth rate is required. To achieve this, you can use various tools such as remote sensing and spatial information. In the present article, ASTER satellite images, cover changes and land use related to a part of Tehran city have been investigated. The review period is from 2001 to 2017. Then, in the next section, the CA-Markov integration model will be used to predict future urban growth.

Assessment and monitoring of forests and rangelands is one of the important and essential aspects for management of these areas. Today, satellite imagery is used as a relatively inexpensive and fast way to study vegetation in different scales, which is evaluated by studying the spectral properties of plants. Field survey and monitoring of vegetation on large scale is practically difficult or, to some extent, impossible due to time and cost. Therefore, the measurement of technology is very beneficial in that it has the advantage of having features such as providing a broad and integrated view of a region, the ability to repeat, streamline the information and the accuracy of the resulting information, save time and costs on other methods. The purpose of this research is to use remote sensing technology to evaluate and measure production and vegetation cover and sustainable development of natural resources. By studying and integrating the results of sampling and field measurements with remote sensing data, it can provide maps with a high level of vegetation coverage in rangelands that are in the management of natural resources and regeneration Damaged pastures are very valuable.

Medicinal plants play a central role, not only as traditional medicines used in many cultures, but also as trade commodities which meet the demand of often distant markets. In this paper, we review global trends in the close relationship between cultivation and wild harvest of MAP species, and then make recommendations on steps that should be taken to achieve a balance between consumption, conservation and cultivation. We absorbed the plan of management of forest and rangeland of khosrow Shirin after 15 years of performance of plan. The plan involve cultivation of medicinal plant and some tress. In this context, cluster level meetings were organized with farmers, traders, herbal healers, public representatives, experts, women selfhelp groups, and nongovernment organizations and officers from government departments. Wild harvesting of MAP will continue to prevail due to the economic reasons outlined above. Sustainable wild harvest management schemes need to be supported by governments and authorities. Management plans need to be established as a standard prerequisite for any such harvesting in the wild. There is a need to monitor and audit the harvesting process to determine whether it is sustainable. Identifying the conservation benefits and costs of the different production systems for MAP should help guide policies as to whether species’ conservation should take place in nature or the nursery, or both.
