La gestion durable des ressources naturelles, notamment dans les pays du Sahel, a toujours soulevé des problèmes dont celui de l’inadaptation des législations nationales y relatives. Le processus d’élaboration et de mise en œuvre de ces législations est à l’image des conditions politiques, socio-économiques et culturelles des pays en question. Le Burkina Faso, pour sa part, a connu plusieurs formes de régimes politiques et, de ce fait, capitalise un certain nombre d’expériences de réformes législatives et réglementaires dans le secteur des forêts et des ressources naturelles.
This document is divided in eight chapters. The first chapter reviews rangelands and rangeland development in Ethiopia. The second chapter is an introduction to the Borana Plateau with ref. to natural resources and pastoral society. It reviews secondary information on geology and sociology, as well as original information on climate, soils, wildlife, plant ecology and water resources for the central Borana Plateau. Chapter three deals with vegetation dynamics and resource use.
The Chinyanja Triangle (CT) is an area inside the Zambezi
River Basin, inhabited by Chinyanja-speaking people
sharing a similar history, language and culture across
the dryland systems of the eastern province of Zambia,
southern and central regions of Malawi and Tete Province
of Mozambique. Chiefs and Chiefdoms play a critical role
in decision making and influencing social relationships. The
Zambezi River, which originates in the Kalene Hills in Zambia
is joined by ten big tributaries from six countries, and is
Reliance on rainfall for agriculture and increased climate change and variability pose growing production risks in developing countries. Agriculture in Sub-Saharan Africa is dominated by smallholder farmers who depend mainly on rain-fed agriculture, putting food security at both household and national levels at risk, especially in the event of drought. Investment in smallholder irrigation becomes a priority in developing countries if food security and national development goals are to be met, as their economies are agro-based.
Malinau District, established through partition in 1999, is the largest district in East Kalimantan and contains some of its largest tracts of forest. With decentralization, the district has sought to generate revenues from its forests, but these efforts have been handicapped by a concurrent lack of institutional capacities to manage rapid forest exploitation and conflicts over claims. Timber extraction and utilization permits (Izin Pemungutan dan Pemanfaatan Kayu or IPPK) have been the main instrument for revenue generation, with 39 IPPK covering 56,000 ha.
The report describes the impacts of forestry decentralization on district finance, local communities and spatial planning, drawing on an 18-month research project in Bulungan District in East Kalimantan Province. It describes forestry management policies following the implementation of regional autonomy, and their impacts on district revenue and local livelihoods. The authors analyze district spatial planning, forest land use and community control over forest lands.
