the goal of this study was to estimate the sensitivity of reference evapotranspiration (et0) to changes in meteorological parameters in the caspian region. long-term meteorological data (1961-2008) were obtained from three synoptic meteorological stations. the region was primarily classified into three climatic zones, based on de martonne climate classification. the penman–monteith equation was...

Crude oil accounts for the lion’s share of the demand for fossil fuels. Within the past few decades, increased oil consumption in a variety of economic sectors has lead to massive release of toxic pollutants and greenhouse gases, most specially Carbon Dioxide, as well as inflicting damages to the Earth like global warming and climate change. Accordingly, it is imperative to explore the relation...

Agricultural production is sensitive to weather and thus directly affected by climate change. Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to systematically integrate these three types of ...

Food sustainability is a significant global concern with drastic change required to mitigate complex social, environmental and economic issues like climate change and food security for an ever increasing population. In this paper, we investigate the roles that digital interactions might play in bringing about more sustainable food consumption practices. To inform this exercise, we set out to un...

In arid and semiarid regions, water demands of different sectors are related to groundwater resources. Therefore, the assessment of its changes is very important to achieve sustainable development and optimal management of aquifers in the future periods. The aim of this study was to evaluate the effects of climate change on Islamabad aquifer. For this purpose, the output of general circulation ...
