The present study employs regional climate model projections for assessing the impact of root-zone water balance and groundwater levels using crop and groundwater models. The projections from Hadley Regional Model 3 (HRM3) for A1B scenario showed an increase in temperature and rainfall (RF) of 1.8 °C and 328 mm, respectively, during mid-century (MC) (2021–2050) for Indian central Punjab. The respective increase in values for the end of century (2071–2098) would be 4.4 °C and 486 mm, compared with present time slice (PTS) (2000–2010). In future, irrigation requirement would reduce, because of increased RF and decreased transpiration from cropped area owing to a shortening of crop duration of rice-wheat cropping system with temperature. The reduced irrigation need in future would decrease groundwater withdrawal resulting in the rise of groundwater level.
Intense bouts of flooding in the UK have increased substantially this century, with the frequency set to rise even further as a result of climate change.
That is the latest warning from the Environment Agency, which said severe flooding over the last decade was linked to extreme weather events and rising sea levels.
The agency highlighted Met Office data showing that there have been 17 record-breaking rainfall months and seasons since 1910 – nine of which have occurred since 2000.

Dedicated to limit the environmental impact and carbon emissions, Lebanon is one of the 195 countries who made history by taking a part in the Agreement at the Conference of the Parties (COP21) in Paris in 2015.
In the same year, the government published the Intended Nationally Determined Contribution (INDC) with the purpose of reduction of the possible risks and irreversible consequences of climate change on its already-stretched economy and natural resources. Although Lebanon’s share in global greenhouse...
Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2
While climate change is expected to affect agriculture and reduce crop yields, the complete effects of climate change on agriculture and the resultant human food supplies are yet to be fully understood.2,3,4
Simulating a Changing Climate
In order to understand how changes in CO2,...
Climate change is an unavoidable phenomenon of natural and anthropogenic origin against which mitigation and adaptation are required to reduce the magnitude of impact and vulnerability, to avoid risk in vegetable farming and to ensure sustainable livelihoods of the agricultural community. Genetic improvement of vegetable crops is an appropriate adaptation strategy to cope with climate change adversities. A combination study of genomics and phenomics provides a clear understanding of the environment's effect on...
This study analyzes effects of climate change (CCh) and of the increase of impervious surfaces on the groundwater recharge in the Alto Atoyac sub-basin (Oaxaca, southern Mexico). Water recharge was modeled based on HELP 3.95D; temperature and precipitation were derived, for a near (2015–2039) and a far distant future scenario, from GFDL-CM3 global circulation model (GCM), which describes the climate of Mexico under the RCP8.5 scenario. Potential recharge loss zones for the period of 1979–2013 were estimated...
