The drylands of Africa, exclusive of hyper-arid zones, occupy about 43 per cent of the continent, and are home to a rapidly growing population that currently stands at about 325 million people. Dry zones, inclusive of hyper-arid lands, cover over 70 per cent of the continent’s terrestrial surface. Outside of the cities many dryland inhabitants are either pastoralists, sedentary or nomadic, or agro-pastoralists, combining livestock-rearing and crop production where conditions allow.

En la no tan larga historia de la Humanidad, nuestros antepasados han luchado con demasiada frecuencia por la tierra y el agua. Aquellos tiempos están nuevamente de actualidad.

Human activities have resulted in unprecedented phenomena and severe impacts for the 21st century such as land degradation, natural resources scarcity, climate change, and a rapid decline in biodiversity. These alterations engender secondary effects such as political conflicts, disputes over resources, social disruptions and sudden shocks of catastrophic weather events which are becoming more frequent in critical regions of the world, particularly in drylands; and exacerbate threats for human, national and international security.

As the world reviews its progress in tackling global poverty and achieving the Millennium Development Goals (MDGs), drylands can no longer be ignored. Drylands account for more than a third of the world’s land surface and more than 2 billion of its people. Yet for too long, drylands and their inhabitants have been neglected in development processes.

Los desafíos y retos que supone la escasez de agua para las poblaciones de las tierras secas se van a ver incrementados tanto en magnitud como en alcance. Dado que la población mundial es ya superior a los 6.000 millones de personas, algunos países han superado los límites de sus recursos acuíferos. Con el escenario actual de cambio climático, casi la mitad de la población mundial habitará áreas con grandes problemas de agua antes del 2030, lo que incluye a una población de entre 75 y 250 millones de personas en África.

Les enjeux et menaces que représente le manque d'eau pour les populations des zones arides sont voués à prendre de l'ampleur. Alors que la population mondiale a dépassé 6 milliards d'individus, quelques pays ont déjà atteint les limites de leurs réserves d'eau. En considérant le scénario actuel de changement climatique, on estime que quasiment la moitié de la population mondiale vivra en zone de fort déficit hydrique d'ici 2030, dont 75 à 250 millions de personnes sur le continent africain.

The challenges and threats of water scarcity to dryland populations are set to increase in magnitude and scope. As the world’s population has swollen to well over 6 billion people, some countries have already reached the limits of their water resources. With the existing climate change scenario, almost half the world’s population will be living in areas of high water stress by 2030, including between 75 million and 250 million people in Africa. In addition, water scarcity in some arid and semi-arid places will displace between 24 million and 700 million people (WWDR 2009).
