Somalia is the longest known case in modern times of a country whose central state has ceased to exist for many years. Although Somalia is often said to be a country in chaos and anarchy, a new form of social organization emerged here some time ago. Indeed, many Somalis appear to have adapted well to their country's statelessness.

Although «urban» and «rural» development are often considered as in opposition to each other and seen as competing with each other for investment and support, many urban centres owe much of their economic base to agriculture. Ironically, one of the best tests of whether rural development is working is whether local urban centres are booming - as increasing agricultural output is served by markets and producer services there, and as real increases in income for a wide range of rural households are reflected in increased demand for goods and services provided by urban-based enterprises.

Hardest hit by desertification is Sub-Saharan Africa, where poverty is more widespread, preparedness for catastrophe is lower, and means for adequately coping with the phenomenon are very weak; two thirds of the arable land will be lost by 2025.The subcontinent needs improved integrated initiatives on local, national und multinational level for a sustainable natural resources management. Environmental Information systems can increase awareness and throw light on decision making processes on the complexity of desertification badly needed by most African countries.
