Es indudable que en la actualidad estamos viviendo un fenómeno climático llamado en tiempos modernos como “Cambio Climático”, cuya evidencia científica es irrefutable. Las causas de este fenómeno mundial se atribuyen al aumento exponencial de las concentraciones de emisiones de gases de efecto invernadero en la atmósfera resultantes de las actividades humanas, entre otras, las provenientes del cambio de uso del suelo y por degradación forestal. Los bosques, a más de la prestación de bienes que ofrecen, tienen un rol fundamental en la estabilidad climática global.

The Kalu Ganga Basin in Sri Lanka is generally flooded once a year. A network of low-lying lands acts as natural retention and storage that captures floodwater, minimizing damage. An increase in the flood frequency has been observed in recent years. It is commonly perceived that this increase is caused by a rise in the frequency and severity of ‘very wet’ precipitation events. We conclude that land-use changes may have played a larger role in generating floods.

limatic and hydrological changes will likely be intensified in the Upper Blue Nile (UBN) basin by the effects of global warming. The extent of such effects for representative concentration pathways (RCP) climate scenarios is unknown. We evaluated projected changes in rainfall and evapotranspiration and related impacts on water availability in the UBN under the RCP4.5 scenario. We used dynamically downscaled outputs from six global circulation models (GCMs) with unprecedented spatial resolution for the UBN.

The Fertile Crescent (FC) is a high biodiversity region where most temperate-zone agricultural species originated and were first domesticated. A favourable environment, a special plant community and an adaptive population combined to initiate the transition from a hunter-gatherer economy to one based on agriculture and food production in the Fertile Crescent.
