چکیده
This study projects water availability and sustainability in Nigeria due to climate change. used Gravity Recovery Climate Experiment (GRACE) terrestrial storage data (TWS), Global Precipitation Climatology Center (GPCC) precipitation Research Unit (CRU) temperature data. Four general circulation models (GCMs) of the Coupled Model Intercomparison Project 5 were downscaled using best four downscaling methods. Two machine learning (ML) models, RF SVM, developed simulate GRACE TWS for period 2002–2016 then projection spatiotemporal changes TWS. The projected assess based on reliability–resiliency–vulnerability (RRV) concept. revealed that linear scaling was over Nigeria. had better performance than SVM modeling area. also there would be decreases during wet season (June–September) increases dry (January–May). Decreases range 0–12 mm periods 2010–2039, 2040–2069, 2070–2099 under RCP2.6 0–17 RCP8.5 season. Spatially, annual are expected increase northern part decrease south, particularly country’s southeast. Groundwater higher all RCPs compared other this can attributed rainfall period.

Sustainability of Small Reservoirs and Large Scale Water Availability Under Current Conditions and Climate Change
Semi-arid river basins often rely on reservoirs for water supply. Small reservoirs may impact on large-scale water availability both by enhancing availability in a distributed sense and by subtracting water for large downstream user communities, e.g. served by large reservoirs. Both of these impacts of small reservoirs are subject to climate change. Using a case-study on North-East Brazil, this...

15 صفحه اولGlobal climate change and tree nutrition: influence of water availability.
The effects of global climate change will regionally be very different, mainly causing considerable changes in temperature and water availability. For Central Europe, for example, increased temperatures are predicted, which will cause increased frequencies and durations of summer drought events. On the other hand, the predicted changes in precipitation patterns will lead to enhanced rainfall du...
متن کاملClimate Change and water in Southwestern North America special feature: water, climate change, and sustainability in the southwest.
The current Southwest drought is exceptional for its high temperatures and arguably the most severe in history. Coincidentally, there has been an increase in forest and woodland mortality due to fires and pathogenic outbreaks. Although the high temperatures and aridity are consistent with projected impacts of greenhouse warming, it is unclear whether the drought can be attributed to increased g...
