Vulnerability assessments have become necessary to increase the understanding of climate-sensitive systems and inform resource allocation in developing countries. Challenges arise when poor economic and social development combines with heterogeneous climatic conditions. Thus, finding and harmonizing good-quality data at local scale may be a significant hurdle for vulnerability research. In this...
As an important factor to be considered, rapid population growth, lack of resources and appropriate management has led the natural hazards threatening human societies increasingly. Although it is impossible to eliminate the effects of natural hazards, however, risk reduction and risk cities against natural phenomena has become the main topics of urban planning and design in recent years. Iran i...
Introduction: Mining is one of the most effective human activities to change the situation in the region, particularly in arid area. The human demand for minerals and energy resources under the ground has made mining and exploration operations inevitable. Mining is one of the common human behaviors with numerous outcomes for the ecosystem along with serious environmental and ecological conseque...
Land subsidence due to groundwater resources extraction is one of the abundance events occurred in Iran. If it is not properly managed, this phenomenon can cause irreparable damage to the affected areas. Population growth and agricultural technology have also led to overexploitation of the groundwater resources in some parts of Iran. The rate of land subsidence due to overexploitation of the g...
Effects of land use on temperatures during severe heat waves have been rarely studied. This paper examines land use-temperature associations during the 2011 heat wave in Greater Houston. We obtained high resolution of satellite-derived land use data from the US National Land Cover Database, and temperature observations at 138 weather stations from Weather Underground, Inc (WU) during the August...
Cities are developing innovative strategies to combat climate change but there remains little knowledge of the winners and losers from climate-adaptive land use planning and design. We examine the distribution of health benefits associated with land use policies designed to increase vegetation and surface reflectivity in three US metropolitan areas: Atlanta, GA, Philadelphia, PA, and Phoenix, A...
Mitigation and adaptation have become two main strategies that governments around the world are focusing on in response to the threat of global climate change. In August 2009, Typhoon Morakot heavily damaged the central and southern parts of Taiwan, causing irreversible damage to the environment, especially in the mountain areas. In this study, the goal is to attain sustainable reservoir manage...
Developing a Framework to Measure Watershed Sustainability by Using Hydrological/Water Quality Model
A framework is built, wherein hydrological/water quality model is used to measure watershed sustainability. For this framework, watershed sustainability has been defined and quantified by defining social, environmental and biodiversity indicators. By providing weightage to these indicators, a “River Basin Sustainability Index” is built. The watershed sustainability is then calculated based on t...
