Persian Gulf – June 1st, 2013

Dust blows off the coasts of Iraq (above) and Kuwait (left) and over the Persian Gulf. The plume of dust partially obscures the Shatt al-Arab, the river formed by the confluence of the Tigris and the Euphrates, and its mouth on the northern end of the gulf.

Egypt – May 30th, 2013

In Egypt, the 24,900 km2 Nile Delta represents about 60 % of the country’s total arable lands, and it is inhabited by about 30 million people. Water and air pollution continue to be a problem for the river. As development in the spheres of agriculture, industry, and urbanization have progressed among the human population, so too have the side effects associated with these practices increased, namely in the form of various pollutants. These pollutants range from agrochemicals to heavy metals to human waste products. With regards to the latter, many of the impoverished cities along the banks of the Nile cannot afford to build or maintain water treatment facilities, meaning that the water that the people living there use is dumped into the river untreated (click here for more information).

Climate Change and the Guadalquivir Basin, Spain

Spain – May 30th, 2013

In the Guadalquivir basin, in the southern part of Spain, agriculture is a key economic sector. Due to its privileged agro-climatic conditions, the region grows a wide range of crops, from cereals, oilseeds, sugar-beet and cotton, to varied fruits and horticulture products and olives.

Intensive and extensive productions coexist as well as market-oriented large, medium-size and small farms. However, this highly productive agriculture and its dependant socio-economic structure will be threatened by climate change impacts on water availability and frequency of extreme events such as drought.

The impacts of climate change on the agricultural sector in this region are expected to have large social significance, as this region has the second largest share of agricultural employment in Spain. In consequence, it will be relevant for this region to analyze CC impacts, vulnerability and adaptation strategies across different geographical locations, economic sectors and social groups.

The main issues concerning water management and climate change in this basin are: highly valuable ecosystems threatened by climate change and agricultural activity (Doñana National Park), technical challenges: improving water use technical efficiency (modernization of irrigation techniques), special institutional setting, different from other river basins in Spain, which poses water management under the shared competence of the regional administration and the river basin authority, that can promote mainstreaming of climate change under the water policies (click here for more information).

Nelson River Spilling into Hudson Bay, Canada – May 27th, 2013

Canada – May 26th, 2013

The Nelson River is a river of north-central North America, in the Canadian province of Manitoba. Its full length is 2,575 kilometres (1,600 mi), draining Lake Winnipeg before flowing into Hudson Bay, into which it can be seen spilling sediments here.

The river has a mean discharge of 2,370 cubic metres per second (84,000 cu ft/s), and has a drainage basin of 892,300 square kilometres (344,500 sq mi), of which 180,000 square kilometres (69,000 sq mi) is in the United States.

The Nelson River watershed is the second largest basin in Canada by population (5,492,879 inhabitants in 2011) and has a surface area about 987,000 km2 among which 472,000 km2 were used for agricultural purposes in 2006. This territory includes 70% of the land dedicated to agriculture in Canada. Due to the vast expanse of cultivated land, more pesticides are used in the Prairies than in any other region in Canada. Aquatic ecosystems are therefore becoming vulnerable to pesticide contamination (click here for more information).

Dust by Senegal River and Cap-Vert Peninsula, Senegal

West Africa – May 25th, 2013

Dust from the Sahara Desert blows westward off the coast of West Africa. The dust is thickest around the border between Mauritania (above) and Senegal (below), with plumes visible just north of the Senegal River (center) and the Cap-Vert peninsula, a rocky promontory extending west from the main sandy areas of Senegal on which the capital city of Dakar is located.
