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.

Despite ambitious desertification control programmes, the area of desertified land has expanded continuously since the establishment of the People's Republic of China, with increasingly serious impacts on important industrial and settlement areas. Only in the new millennium is a reversal of this trend in sight.

In the ten years since it came into being, the United Nations Convention to Combat Desertification (UNCCD) has had little or no effect on the further encroachment of deserts. More than 80 countries have submitted National Action Programmes to combat desertification, but they appear to lack the financial and political commitment to implement them. What are the causes behind the UNCCD's weakness? How can the Convention be incorporated more effectively and efficiently into the architecture of international development?

People-centred early warning systems empower communities to prepare for and confront the power of natural hazards. However, the efficiency of such systems is to be measured in terms of lives saved and reduction in losses, which is directly related to the execution of an anticipated response by the people and institutions once a warning is issued.This paper addresses traditional views on early warning systems, and what it takes to transform them into efficient, people-centred systems.

The series of dramatic natural events is never ending. 2005 again illustrated that natural disasters are unavoidable. For disaster prevention systems to function properly, investments in raising risk awareness are key.

Afghanistan, Sierra Leone and Somalia: these three countries stand for different histories of a fragile state.The author of this article analyses different case studies to determine the various causes, such as the role of ethnic identities, claims to power by clans and other sub-state groups, or the lack of societal representation within the governments. For the author, the greatest risk to a state is violence, which can quickly spiral out of control in a weak state and lead to chaos.

Urbanisation and economic transformation - the growth of non-farm, industrial and service sectors - offer many opportunities for improvements in poor people's lives.The crucial challenge is to ensure that places work better for people, providing an enabling and supporting environment for changing livelihoods and economies. But all too often there is a failure to recognise and manage the urban transition, resulting in the continuing urbanisation of poverty, vulnerability and exclusion.

Looking at several large-scale land deals in Mozambique, Tanzania and Zambia, this extraordinary documentary highlights the nuanced impacts of these investments. Small-scale farmers and producers, national government officials, and African policy-makers unpack the deals, showing that there are winners and losers when providing investors access to large tracts of land in Africa. For example, land deals impact differently on women and youth, and altering land regimes also impacts on access to other natural resources such as water, fish, and local indigenous vegetables.
