Many factors are involved in urban heat island development,such as lack of green spaces,improper choice of building materials,densification,and other human *** aim of this research was to quantify the effects of land-use/land-cover(LU/LC)changes on urban land surface temperature(LST)during a 25-year period(1993–2018)for the semiarid Shiraz City in southern Iran using Landsat data(TM,ETM+,and OLI/TIRS)and machine learning *** main LU/LC classes,such as orchard,vegetation,bare surface,asphalt cover,and built-up areas,were identified using a support vector machine *** images were used to retrieve normalized difference vegetation index(NDVI)and normalized difference built-up index(NDBI).The results showed that the mean LST over the entire study domain increased considerably between 1993 and 2018,due to urbanization,decrease of green areas,and increasing industrial ***-up areas increased considerably by 25.8%from 80 to 100.6 km^(2) between 1993 and 2018,while vegetation cover decreased dramatically by 69.3%.Mean LST increased from 38.4 to 40.2℃ during the 25-year period with a significant increase of 3.9℃ between 2013 and *** addition,the Urban heat island Ratio Index(URI)displayed a substantial upward trend during the 25-year period.

Water Status in the Syrian Water Basins

引用

Open Journal of Modern Hydrology 2012年第1期2卷 15-20页

作者： Khaldoon A. Mourad ronny berndtsson 不详

Syrian water resources face economic and physical water scarcity. This together with a large population and development increase and the climate change may lead to increasing risks for international controversies and disputes in the coming decades. According to FAO, the available water resource per capita AWPC is going to be half by 2025. Depending on its seven water basins, this paper analyses water demand and supply in the Syria with their projections till 2050. The paper shows that two of the seven Syrian basins need a specific concern as they face water scarcity problem. However, two basins have extra water. Therefore, the paper focuses on the need for a sustainable water management, which takes all nonconventional water resources into account to contribute in the Syrian water balance such as rainwater harvesting and wastewater reuse.

Can Integrated Water Resources Management Contribute to Sustainable Peace in the Middle East?

引用

Journal of Geoscience and Environment Protection 2013年第1期1卷 1-8页

作者： Khaldoon A. Mourad ronny berndtsson Karin Aggestam Center for Middle Eastern Studies Lund University Lund Sweden Department of Political Science Lund Sweden Department of Water Resources Engineering Lund University Lund Sweden

Water resources issue in the Middle East is an important question related to the 4th June 1967 line in the Middle Eastpeace process. This paper focuses on possibilities within the Integrated Water Resources Management (IWRM) approach to contribute to the peace process between what is calledIsraeland Arab countries emphasizing fruitful cooperation to resolve the 4th June 1967 line issue. The paper shows that start of a possible cooperation could be founded on interest-based negotiations and built on IWRM principles by a simple geographical allocation plan for theLake Tiberiaswater together with a joint environmental protection plan to build cooperation instead of confrontation and integration instead of fragmentation. In a better cooperative climate, withdrawing from the 4th June 1967 line could be a possibility because negotiation results would incur safer access to sustainable water resources and a comprehensive peace.
