1 - Assessing the consequences of visa cancellation with the Republic of Azerbaijan on the sustainable development of the northwestern of Iran
Abolghasem mahmoodi afsaneh bashiriMany countries around the world use the visa cancellation policy as a privilege to attract tourists and develop sustainable tourism.

Since 2010, the world tourism organization has supported the growing trend of visa cancellation and tourist entry facilities. Iran is no exception to this rule and intends to benefit from the visa cancellation policy. Of course, the political benefits of a visa waiver for Iran is more important than tourism benefits. Northwestern region of Iran is important for the implementation of the visa cancellation policy due to special conditions; Proximity to 4 foreign countries, the existence of many tourist attractions and the need for further development. Among the four neighboring countries in the northwestern region of Iran, the Republic of Azerbaijan is very importance due to the same ethnicity, religion and culture, as well as some political issues. The visa cancellation with this country has had many positive and negative effects on the region tourism statistics, however, this trend has not had a positive impact on the sustainable development of tourism the study of these effects and providing a model for other regions of the country is one of the main objectives of this study which by combining quantitative and qualitative research methods, the result indicates that The visa cancellation with the Republic of Azerbaijan has been done with a political attitude and has not had significant positive effects on the indicators of sustainable tourism development in the northwestern region of Iran.

The study of plants species provides one of the required criteria for distinguishing a wetland area and is used in the process of ecological demarcation of the wetland. The vegetation in the water body and it’s around was studied by 42 sampling plots and its species were identified. 180 species belonging to 124 genera and 48 families were identified. The Poaceae, Asteraceae, Cyperaceae, Fabaceae, Brassicaceae and, Caryophyllaceae were the most abundant families, respectively. Classification of plants based on biological form showed that the highest biological form was related to therophytes with 43%. After that, hemicryptophytes with 18% and, geophytes with 16% had the highest ferequency, respectively. The plants in terms of geographical distribution, mainly belong to the cosmopolitan elements. 35% of species belonged to the obligate. The facultative upland with 32%, facultative wetland with 15%, facultative with 14% and Upland with 4% consisted other wetland indicator plants, respectively. Manuscript profile -

Therefore, it is important to recycle or prevent leakage and to remove them from contaminated water. There are various ways to remove and recycle oil; including physical, mechanical, biological and photochemical methods, filtration and the most widely used way is absorption methods. The choice of an economically suitable hydrophobic absorber should be easy to handle, not expensive, and not be classified as hazardous. The adsorbent material can be organic or inorganic. Organic materials usually include plants, animals, or other high-carbon compounds (such as food waste, rice husk, macroalgae, algae, creatine, etc.). It is also possible to use organic compounds produced in industries such as petroleum and fertilizer industries. Inorganic compounds used as adsorbents are usually substances such as: soil, clay, mud, zeolite, minerals, metal oxides and hydroxides. Manuscript profile -

Environmental Impact Assessment ensures the environmental concept of sustainable development by providing the necessary environmental information to determine the environmental friendliness of a proposed project. Mechanical harvesting of aquatic plants along with biological and reed harvesting in the whole area of West Wetland and opening the entrance of Chafrud River were the main activities that could be implemented in this project. Mechanical harvesting operations are performed with a Harvester machine and reed harvesting is done with a motor saw or manually. The most important activities of the project are mechanical harvesting (reed harvesting and immersion of aquatic plants floating with the Harvester machine), restoration and cleaning of waterways (Chafrud River), dewatering and rehabilitation of West Wetland, biological control and operation of wooden bridge and bird watching station. Environmental parameters, consequences and nature of the effect, impact time, magnitude of the effect and the scope of the effect were investigated and the positive and negative effects of the design were determined.

5 - Comparison of the effects of pollution caused by Saravan wastes on Kacha River during drought and wet year

The leachate produced flows in different layers of waste and carries toxic and polluted substances to surface or groundwater. Kacha River, which carries the contamination load from Saravan landfill, flows into Siahrud River; Siahroud passes through this lands on its way, flows to the north and after joining Goharroud, enters the eastern part of Anzali Wetland. In this study, sampling stations were located in Saravan landfill and Kacha River and sampling was done in winter and summer and COD, BOD, TDS, pH, EC, ammonia, phosphate and nitrate parameters were measured. Comparison of the results of leachate analysis of Saravan landfill and Kacha River in summer and winter showed that all parameters, including BOD and COD parameters, which are indicators of contamination load in the Kacha River, increased in the drought season (summer) compared to the wet season (winter) Which indicates the amount of more pollution from Saravan landfill to Kacha River and from there to Gohar River and finally Anzali wetland.

The release of rubber wastes into the environment causes many problems, including diseases, their bad landscape in nature, and terrible fires caused by their accumulation and environmental pollution. Also, rubber can be reused due to its non-degradability and elastic properties; as a result, the management of worn tires has a particular importance. There are several ways to manage rubber waste that can be safe and effective when done properly. These methods include sanitary landfilling, incineration, pyrolysis, milling, reuse at various scales, and re-coating. In this article, each method is reviewed and their advantages and disadvantages are stated. Also, there are examples of different applications of rubber waste in various industries. Manuscript profile
