Avant-propos La notion de désertification se définit comme une dégradation des sols en zone aride, semi-aride et subhumide sèche, souvent appelée simplement « zone aride ». On estime qu’elle résulte d’une combinaison de facteurs, parmi lesquels les changements climatiques et l’activité humaine. Plus d’un tiers de la superficie totale de la terre est considéré comme zone aride. En termes démographiques, c’est un cinquième de la population totale du globe qui vit en zone aride déjà dégradée ou menacée de désertification.

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.

This paper describes a novel effort at developing index-based insurance for locationaveraged livestock mortality as a means to fill an important void in the risk management instruments available to protect the main asset of pastoralists in the arid and semi-arid lands of Kenya, where insurance markets are effectively absent and uninsured risk exposure is a main cause of the existence of poverty traps.

This guide summarizes international human rights standards applicable to involuntary displacement caused by public and private infrastructure and urbanization projects. It provides guidance for all involved parties: urban planners and architects, public authorities, the legal community, national or international financing entities, governments, civil society, and affected populations. It aims to provide guidance to assist in the execution of development projects that respect, protect and fulfil the human right to adequate housing of the communities that will be affected by them.

This paper evaluates the effectiveness of a new index-based livestock insurance (IBLI)
product designed to compensate for area average predicted livestock mortality loss in
northern Kenya, where previous work has established the presence of poverty traps. We
simulate household-specific wealth dynamics based on a model parameterized using rich
panel and experimental data from the region. The simulations allow us to investigate
patterns of willingness to pay for asset index insurance that is imperfectly correlated with
