Global mean surface temperatures have risen by 0.85 ± 0.20 °C, over the period 1880–2012, and projections of future climate change suggest further global warming (IPCC 2013). Warming of the global climate is expected to be accompanied by increase of global precipitation, as warmer air is able to hold more water vapour (Wentz et al. 2007). However, precipitation changes are expected to differ fr...

introduction: evaporation and evapotranspiration are two major components of hydrological cycle which are very important for agricultural studies as well as water resources management. so far, various methods have been addressed for the estimation of daily reference crop evapotranspiration (et0). among them, fao penman-montieth 56 (pmf-56) (allen et al., 1998) is widely used as a standard metho...

Introduction ‘Everybody talks about the weather, but nobody does anything about it’, said Mark Twain. But this famous quote is decidedly inaccurate: people have long contemplated weather modification, and both adapt or adjust to weather conditions, and move towards or away from certain climatic regimes. Southern Africa generally has a high coefficient of rainfall variation, making droughts a fr...

In the coming years, climate change is predicted to impact irrigation water demand considerably, particularly in semi-arid regions. The aim of this research investigate expected adverse impacts on management Saudi Arabia. We focus influence requirements Al Quassim (97,408 ha) region. Different models were used for intermediate emission SSP2-4.5 and high SSP5-8.5 Coupled Model Intercomparison Pr...

Abstract Human-induced climate change significantly alters the spatiotemporal characteristics of zones, which drives agricultural land use and ecosystem change. However, detectability shifting zones rate time changes has yet to be adequately addressed at regional-to-local scale. We mapped analyzed temperature precipitation across Kenya during past four decades, linked those shifts in geographic...

Developing cultivars with traits that can enhance and sustain productivity under climate change will be an important climate smart adaptation option. The modified CSM-CERES-Pearl millet model was used to assess yield gains by modifying plant traits determining crop maturity duration, potential yield and tolerance to drought and heat in pearl millet cultivars grown at six locations in arid (Hisa...

Introduction: Global warming is one of the most important environmental problems that have raised researchers’ attention. The present study aimed to analyze heat stress trends using the Wet Bulb Globe Temperature (WBGT) index in the country of Iran during the summer over a 30-year period. Materials and Methods: Daily summertime statistical data regarding mean temperature and mean relative humi...

the objective of this study is to investigate of climate change in gorgan river-gharesoo basin and these impacts of this phenomenon on regional land use change, as well as provide guidance on the effective management and conservation of natural land area. analysis of climate data including rainfall, average temperature and relative humidity of nine synoptic stations in this area from east to we...
