This thesis gives an overview of the Maasai livestock economy as it has developed between 1890 and 1990. Particularly, it analyses the processes and policies of land use and landownership of the Maasai pastoral areas in Kajiado district, Kenya, from the arrival of the Europeans until the recent massive individualization of land tenure. The loss of grazing pastures due to increased cultivation, the establishment of game parks and mineral exploitation is said to undermine the livestock economy of Maasai pastoralists in Kajiado district.

This chapter explores the possibilities and limits of law and institutions as instruments for generating changes in environmental behaviour. First, an overview of the different schools of thought on law and natural resources is presented. It appears that the overall trend with regard to land and common property resources is orientated towards: 1) a bottom-up/sociological approach to the law-making process, and 2) devolution of powers to local communities in a setting of comanagement.

The National Land Act of 1964, designed to unify legislation concerning land, formally abolished the various local systems of land law in Senegal. The implementation of the various urban land regulations and the efforts to restructure and regulate the spontaneous settlements which were started in Ziguinchor, the capital of the Casamance, in the 1970s resulted in a great number of urban land conflicts. This paper reviews Senegalese law relating to urban land.

The papers included in this volume were earlier presented at a conference on the settlement of land claims in Africa, which was held in Amsterdam in September 2003. The papers are written primarily from an anthropological perspective.

Compte-rendu d'un séminaire sur les recherches pour le développement d'une agriculture durable au Bénin qui s'est tenu le 9 septembre 1993 à Amsterdam.

Pendant l'année 1982 et une partie de l'année 1983 l'auteur a effectué une recherche au Sénégal avec la collaboration de M. Sypkens Smit, anthropologue. Le thème central de la recherche était l'interaction entre les différents systèmes de droit foncier. Le présent rapport relate la phase préparatoire de la recherche, ainsi que les activités des deux chercheurs sur le terrain, en Basse Casamance. Le chapitre sur "Les aspects anthropologiques du droit foncier: le cas d'un village diola" est de la main de M. Sypkens Smit.
