What's Special About Wildlife Management In Forests?: Concepts And Models Of Rights-Based Management, With Recent Evidence From West-Central Africa

Décembre, 1998
Mali
Afrique sub-saharienne

Wildlife consumption is an integral part of the livelihood and trade patterns of many peoples in the developing world, and highly valued by them. Yet to date the dominant models of wildlife management in areas of high – and allegedly unsustainable – consumptive use have favoured the exclusion of the users from the resource and the denial of its local values. This gives little incentive to rural dwellers to manage wildlife sustainably.

The controversy surrounding eucalypts in social forestry programs of Asia

Décembre, 1996

Social forestry emerged amidst important changes in thinking about the role of forestry in rural development and a growing need for fuelwood. In an attempt to alleviate the fuelwood crisis, the World Bank encouraged the planting of Eucalyptus species in its social forestry programs in the 1980s. Eucalypts were the chosen tree species for the majority of social forestry projects because they survive on difficult sites and out-perform indigenous species and most other exotics in height and girth increment, producing wood for poles, pulp and fuel more rapidly.

The Great Green Wall initiative for the Sahara and the Sahel

Décembre, 2007
Afrique sub-saharienne

Desertification has had an acute impact in Africa, particularly in the Community of the Sahel-Saharan States (CEN-SAD), which is characterised by climate ranging from hyper-arid to dry sub-humid. The local communities and their livelihoods are heavily dependent on the increasingly fragile natural resources. This note, conducted by the Sahara and Sahel Observatory (OSS) on the request from CEN-SAD, summarises the results obtained from available documentation and consultations from experts and practitioners for the preparation and implementation of the Great Green Wall in the region.

Analytical situations of land degradation and sustainable management strategies in Africa

Décembre, 2007
Afrique sub-saharienne

In the face of trends towards a widening “food gap” and general poverty, this paper attempts to address the problem by discussing the methodologies necessary for sustainable land management to ensure improved food security, rapid economic development and poverty reduction in developing countries of Africa. The authors explain that the population of the world has been increasing at an exponential rate over the past few decades. Present projections suggest that it will be 11 billion by the year 2100.

Fighting an Uphill Battle: Population Pressure and Declining Land Productivity in Rwanda.

Décembre, 1995
Afrique sub-saharienne

Report draws attention to the structure of landholding as a set of mechanisms through which demographic changes in agrarian societies can alter the natural environment: demographically-induced change in the structure of landholding: farm holdings generally become smaller as an ever-increasing number of households enter the agricultural work force and seek to derive their livelihood from this fixed resource base holdings tend to become more fragmented, not simply in the number of parcels operated but in the distances between parcels, as farmers look harder and farther for whatever bits and p

Impact of carbon value on profitability of improved fallow agroforestry systems in Kigezi highlands, Uganda

Décembre, 2003
Ouganda
Afrique sub-saharienne

The economic advantages of improved agro forestry fallow systems over traditional continuous cropping systems are important tools that can be used to influence the choice of land use options at household levels. In Kigezi highlands Uganda, the upper parts of farmers’ crop field terraces are degraded due to continuous cropping. Improved fallows are being promoted in order to increase soil productivity while increasing fuelwood production.

Fuelling exclusion? The biofuels boom and poor people's access to land

Décembre, 2007
Afrique sub-saharienne
Amérique latine et Caraïbes
Asie méridionale

The policy debate about the merits and demerits of biofuels is growing and changing rapidly, with concerns being voiced over their effectiveness for mitigating climate change, role in recent food price hikes and social environmental impacts. This study contributes to these debates through examining the current and likely future impacts of the increasing spread of biofuels on access to land in producer countries, particularly for poorer rural people. It draws on a literature review of evidence drawn from diverse contexts across Africa, Asia and Latin America.

Land suitability for oil palm in Kalimantan, Indonesia

Décembre, 2006
Indonésie
Asie orientale
Océanie

There is an increasing global demand for oil palm, but its production provokes societal debate on the environmental and social aspects that surround it, particularly in southeast Asia. This study, at the request of request of the Dutch Ministry of Agriculture, Nature and Food Quality (LNV), ISRIC-World Soil Information, Alterra and Plant Research International, assessed the biophysical land suitability for the production of oil palm in Kalimantan, Indonesia.

Land tenure and fast-tracking REDD+: time to reframe the debate?

Janvier, 2013
Népal
Papouasie-Nouvelle-Guinée

This paper argues that legal reform of land tenure will not take place fast enough to enable developing countries to reduce carbon emissions from deforestation and forest degradation through REDD+. It highlights that a global agreement on REDD+ is needed by 2020, if the mechanism is to have a significant impact on mitigating climate change. However, legally defensible and enforceable land tenure rights, while a key enabling condition for effective and equitable REDD+, will not be achieved in most forest countries before this date.
