Sectional view of sand dam
Sand dams. Drought is the most serious natural hazard facing Eastern Africa in terms of severity and frequency of occurrence. The most seriously affected areas are Arid and Semi Arid Lands (ASALS) that face frequent reduction of water or moisture to significantly below the normal or expected amount Pastoralists and agro pastoralists who occupy this vast region barely meet basic water requirements. Consequently they suffer from livelihood losses, hunger, diseases, conflict and internal displacements. The worst affected are women and children who may have to walk all day long in search of water.

Due to limited and unreliable rainfall most rivers are ephemeral seasonal sandy bed streams and only experience heavy water run-off for short periods of time after rain. During such periods of high flows, large quantities of sand are transported downstream while others get trapped on the upstream sides of rocks ledges along the stream. Such sand traps form natural aquifers that are capable of providing clean adequate water if well harnessed. Using appropriate technologies this can be exploited for water storage in the form of sand dams.

You can have a green Christmas.
Green living (or sustainable living) is about practical choices, large and small, to preserve the earth and have a better quality of life. It is a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources and his or her own resources.

In order to make sustainable choices, it is very helpful to have solid, reliable information that tells us which behaviors are sustainable and which are unsustainable. In quantitative terms, which actions will make the greatest difference, and should be prioritized. Green living can be high tech (buying a hybrid vehicle), low tech (green cleaning, or completely "back to nature." It can be smart grid or off the grid. Sustainable city living explains some of the areas of action for a city dweller.

Practitioners of sustainable living often attempt to reduce their carbon footprint by altering methods of transportation, energy consumption and diet. Proponents of sustainable living aim to conduct their lives in ways that are consistent with sustainability, in natural balance and respectful of humanity's symbiotic relationship with the Earth's natural ecology and cycles. The practice and general philosophy of ecological living is highly interrelated with the overall principles of sustainable development.
