Water Dilemma in Isfahan and International Tourists' Effect on It Water Dilemma in Isfahan and International Tourists’ effect on it By: Sheyma Karimi Supervisor: Saeid Abbasian Master’s dissertation 15 credits Södertörn University | School of Social Science Abstract Tourism is one of the leading industries, in terms of international trading between countries. In addition to receipts received at destinations, international tourism has also generated US$211 billion in exports through international passenger transport services. The study is conducted in Isfahan, a city in center of Iran. The city is unique in its cultural heritage and archeology. It is one of Iran's oldest cities at more than 1,500 years of age. An important cultural and commercial center, Isfahan is Iran's third largest metropolitan area. Isfahan experiences an arid climate, like the rest of the Iranian plateau with low rainfall. Isfahan has a high capacity to attract international tourists to provide a better understanding of Iran’s history, culture, and natural environment to the world. Zayandeh Rud which means “life-giving River” is the largest Iranian plateau and the most important surface water in Isfahan. It starts from Zagros Mountains and ends in the Gavkhouni Swamp, a seasonal salt lake in the southeast of Isfahan. The catchment area has been affected by two drought periods within the last 15 years. Decreasing surface and groundwater availability has been accompanied by an increase in water withdrawal for irrigation, domestic uses, industry, and water transfers to neighboring provinces. This has led to severe ecological and social consequences. This study identifies the potentials of Isfahan in attracting international tourists and also evaluate the water crisis that the city faces. The research is based on qualitative method. The primary data is gathered through face to face and phone interviews and questionnaires. The results show some finding solutions to water crisis in Isfahan and some suggestions for improving tourism industry in the city. Keywords: Tourism Industry, International Tourists, Water Scarcity, Water Management, Climate Change i Acknowledgments I would like to express my sincere gratitude to my supervisor, Saeid Abbasian for his intelligent guidance and helpful and essential advices and comments throughout the time I have been working on my thesis.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. Precipitation Refers to any or all of the forms of water particles, whether liquid or solid, that fall from the atmosphere (e.g. rain or snow). Drought is a recurrent feature of climate that is characterized by temporary water shortages relative to normal supply, over an extended period of time – a season, a year, or several years. Water Scarcity Refers to the relative shortage of water in a water supply system that may lead to restrictions on consumption. Desertification means land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities. iii Table of Contents Abstract

There is a variety of important landforms in Iran. As national capital, they are used for economic purposes and also research and education aims. Some of the specific landforms are in danger of destruction due to excessive and inappropriate exploitations. If this type of operation continued ecological imbalance in the region will follow. Thus, protection of the geologic heritage for better protection of the environment and for scientific and educational applications seems necessary. Geo-conservation attempts to protect these features of the earth to avoid their decay. The purpose of this research is to conduct a hypothetical coding pattern for landforms of Iran. Identification, listing, programming, design of coding system, registration and definition of standards are performed to define buffer zones for the landforms. This ID assignment is to be suggested to the ministry of Science, Research, and Technology of Iran for implementation and further studies. With implementation of this coding system and access to a comprehensive database, execution of many plans can be performed with proper recognition of the area.

  • Determination of the Effective Factors on the Water Balance of Urmia Lake Basin with a Focus on Precipitation Trends
    Journal of Hydraulic Structures J. Hydraul. Struct., 2020; 6(2):95-115 DOI: 10.22055/jhs.2020.34399.1143 Determination of the effective factors on the water balance of Urmia Lake basin with a focus on precipitation trends Abdolah Hosseinpour 1 Ali Mohammad Akhoond-Ali2 Mohammad Reza Sharifi2 Ali Kalantari Oskouei3 Abstract Prevention of water loss for the Urmia Lake due to the drought is environmentally crucial for the lake basin and it seems that, the analysis of the historical process of factors governing the water mass balance equation for the catchment leading to the lake can provide insights on what has to be done. In order to do that, statistical significance for potential breaking points and rate of changes over time points of precipitation and runoff for 25 hydrological basin stations based on the data regarding Annual precipitation and Annual runoff related to the whole span of the lake basin from 1977 to 2019 has been studied and surveyed using Mann-Kendall test, Petit test and Sen’s Slope Estimator. For all hydrological basin stations breaking points have been observed in the water discharge time points from 1993 to 2005 and the decline of water discharge. Significant increase in precipitation in the entire Urmia catchment area of about 0.16 mm at a indicates its stability during the study period. The annual runoff of the studied basins into Lake Urmia in the two time periods before and after the discharge drop were estimated at 4.671 and 1.885 billion cubic meters per year, respectively, indicating volume reduction of 2.786 billion cubic meters (59.6%).

For many centuries it has provided the basis for a rich and prosperous region based around the ancient city of Isfahan. Analysis of water supplies and demand over the past 50 years in the Zayandeh Rud basin indicates that despite large investments in water resources development, the basin remains just as vulnerable to drought as it always has been. During the period of analysis two trans-basin diversions and a storage reservoir have been constructed which have more or less doubled the annual supply of water to the basin. But with each water resource development, extractive capacity for irrigation, urban and industrial use has increased by the same amount, so that all new water is allocated as soon as it is available. The most recent developments, since 1980, have actually increased vulnerability to drought because extractive capacity is greater than average flow into the basin. Whenever demand exceeds supply all water is extracted from the basin and the tail end dries up. During the past 50 years flows into the salt pan at the downstream end of the basin have been negligible for more than half the time.

    Rohan Freedman Cape Elizabeth High School Cape Elizabeth, ME Iran, Factor 2: Water Scarcity Iran: Securing Water and Revitalizing the Agricultural Sector Through the Improvement of Irrigation Efficiency With a long history of agriculture dating back to 10,000 BCE, the Islamic Republic of Iran was historically known as a primarily agricultural nation (“ĀBYĀRĪ”). However, the nation of Iran was transformed in the 20th century by the discovery of oil, resulting in rapid urbanization and sadly, losing its agricultural identity. Before the discovery of oil in 1955, 75% of Iran’s population lived in rural areas (Kent). After 1955, as foreign exchange revenues from oil boomed, subsidizing food, public education, health care, and water, investments in agriculture did not keep pace, causing a decline in agricultural production and contribution to the GDP (“Iran”). As a result, in a rapid reversal, 75% of Iran’s population now lives in urban areas (Kent). This national movement of people to towns and cities in search of employment opportunities has had negative ramifications on agriculture, such as: a significantly smaller agricultural workforce, a decrease in crop production, and a decrease in investment in agricultural technologies. Iran is losing its agricultural sector, and with it, its self-sufficiency in food production. This does not bode well in today’s changing world where oil consumption and prices are rapidly falling as the world moves toward greener energy sources. Iran has survived thus far, as a net importer of foods, providing for its people by subsidizing imported foods with oil revenues. However, climate change has made reliable imports from trading partners, Russia and India, unpredictable, as these countries suffer droughts and cut exports (“The Family”).
