The goals were to investigate soil spatialdistribution patterns of metals; their potential ecological risk; and sources. The Hakansonpotential ecological risk index and index of geo-accumulation (Igeo) were used forevaluating the condition of soil heavy metal enrichment and the extent of potentialecological risk. Results demonstrated that the mean concentrations in the agricultural soilswere 2.23 mg/kg for Cd, 5.3 mg/kg for Cu, 38.002 mg/kg for Pb, and 13.84 mg/kg for Zn.The average concentrations of Cd and Pb in the agricultural soils were higher than averageworldwide soils and for Cu and Zn, values were lower than average worldwide soils. Thespatial mapping of the distribution of heavy metals produced by kriging interpolationshowed similar patterns for all heavy metals, and higher concentrations of all heavy metalswere observed in the western and southern parts ...

Therefore, communities require tools for determining the biosphere dynamics and the biophysical limitations of earth in order to assess the systems subdued
by humans. The ecological footprint is among the most important tools in this regard. It evaluates the relationship between humans and resources and is defined as the total area of land and water in different ecological levels,
needed to produce all the resources that people consume, and absorb the wastes they produce. The ecological footprint calculation is in fact the expansion of a quantitative method to illustrate the importance of investigating the effects the inhabitants’ consumption has on the productive
and non-productive land systems. This method can be employed in any area with comparable results. In this study, the ecological footprint of Isfahan was estimated considering the five basic factors of urban life: food, shelter, transportation, goods, and services. In 2011, the per capita ecological
footprint was calculated as 3.9 global hectares. This means that, the productive land and sea required for providing the needed resources and the sinks to absorb the waste resulting from the activities of each Isfahan citizen is 3.9 global hectares.

Dams, in spite of having some socioeconomic benefits, cause irreparable environmental damages. Environmental Risk Assessment analyses risks by ranking or comparing them with target values (Functional goals or Legal Requirements) in decision making process. Risk Assessment includes identification of affected Environment, Spatial-temporal Modeling, assessment of main ecological components, estimating risks quantity and comparison with existing criteria. The aim of this study is introducing a method for dam risk assessment that calculates Risk Levels, based on criteria such as cost, time, resources and expertsòpinion, and could achieve proposed control mechanisms for reducing the risk level of dam construction activities. In this case, earthquake risk in the location of Ekbatan dam was studied. For this study, Environmental risk coefficient was calculated by multiplying three factors: Impact Range, Probability of Occurrence, and Environmental Degradation. To prioritize and weight the effects of criteria, Analytic Hierarchy Process (AHP) was used. According to the results, the first priority in management strategies was " Education of downstream society to implement emergency action plans " with the final weight of 0.7155. " Education of strategies and actions for emergencies conditions " with the final weight of 0.2364, " Completing Earthquake forecasting supplies and equipment to avoid sudden attacks " with the final weight of 0.1989, " Preparation of equipments, affairs and supports to help in emergency situations " , and " Construction downstream detention and checking structures " were the next priorities.

than before. Thus having information about these changes is essential for management and restoration of ecosystem`s sustainable
normal order. Landscape metrics are quantitative tools of landscape situation. These metrics can give us a lot of information about
the structure and changes of landscape components. This study has been performed to investigate the landscape changes in
Golpayegan city located in Isfahan province in central Iran. In order to preparation of land cover maps and change analysis, satellite
imagery 1972 (TM) and 2010 (ETM +) and class area, patch density, number of patches, mean patch size, edge density and mean
shape index metrics were used. For analysis of landscape fragmentation, various metrics of landscape pattern in class level were
calculated using the Fragstats software. Landscape metrics analysis shows that medium ranges have been replaced by agricultural
lands, poor ranges, residential lands and bare lands. According to the results, increasing in the number of patches and decreasing
in the area average are important indicators of decomposition that indicate the destruction and fragmentation of the landscape. The
results of this study can be used in land evaluation, environmental studies and planning and integrated management for rational
utilization of natural resources and reducing of resource degradation.

This phenomenon causes a lot of environmental and socioeconomic problems in Iran and several other Middle-Eastern countries. A Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used for trajectory analysis in order to reconstruct the origins of air masses in dust storms over several cities in the Western Parts of Iran. Backward trajectories analysis by HYSPLIT model showed that the main source of two occurrences of dust storms over several Iranian western cities has been originated from Syria passing through Iraq and arriving at the Western part of Iran. The Moderate Resolution Imaging Spectroradiometer (MODIS) images was used to monitor the monthly vegetation changes in the dust storm source areas. The Enhanced Vegetation Index (EVI) was obtained from recent MODIS vegetation data (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009). Results revealed that source areas anthropogenic activities that reduced vegetation cover and activated wind erosion caused EVI numerical value reduction and dust storms occurrence over several Iranian Western cities.

One of them is ecological footprint that is the total area of land, to produce all the resources a population consumes and to absorb all of the wastes it generates. An important impact of human activities on the environment is climate change that relates to the concentration of greenhouse gases in the atmosphere. The most important gas is CO 2 which is released to atmosphere as a result of burning fossil fuels in daily life of human activities. A main part of increasing CO 2 in urban atmosphere is road transportation; so estimation of ecological footprint of it can describe the situation of consuming fossil fuels in a city. To do so, the amount of different fuels consumed in a period of time, the area under transportation constructions and also the energy consumed in the process of network construction and annual road maintenance should be regarded. In this study the ecological footprint of transportation activities in the city of Isphahan in central Iran was estimated at 0.4 global hectares. It means that for each Isphahan resident, 0.4 global hectares area is needed to sequester the CO 2 released to atmosphere from different transportation activities.

Iran's western part dust storms considered hazardous problem that cause many environment and socio-economic impacts. Sensitive areas to desertification were identified by Environmental Sensitivity Areas (ESAs) in the source area of western part of Iran's dust storms for 2003 and 2007. RS and GIS data have been used to assess the desertification severity and its relation with the pervasive dust storms occurrences in western parts of Iran. The comparison of ESAs maps over studied years, indicate the severity of desertification has been increased in 2007. Source area desertification may cause western part of Iran's dust storms. Generally, the occurrences of western part of Iran's dust storms have become more frequent over studied years.

However, there are little documentations on application of SWOT analysis in ecotourism. An assessment on systematic use of SWOT analysis was carried out in the present study to highlight the applicability of the SWOT technique in detailed investigations. In this study, based on field surveys and questionnaires (on Anzali Wetland and the local population), matrix of internal and external factors (threats, opportunities, weaknesses and strength) influencing tourism development in Anzali Wetland were evaluated within the framework of SWOT analysis and SO, WO, ST and WT strategies were identified. Based on the obtained results, the total score of 3.22 in IFE matrix suggests good condition of the system and high internal strength of the tourism development related to internal factors and the final score of 2.93 in the EFE matrix represents poor condition related to the external factors which means external factors have not been utilized properly; Thus appropriate planning and organizational management practices are required to deal with these factors. The study further proposes solutions, operational priorities and strategic planning according to environmental and local conditions of Anzali Wetland. Since the tourism industry in Iran is still in its early stages, particularly in Anzali Wetland region, the findings could help decision makers to estimate better the weaknesses, strengths, threats and opportunities, and to develop tourism industry in the region.
