The paper analyzes land use changes, notably cropland expansion, in SE-Niger from the mid-1980s to 2011. It scrutinizes land use trajectories and investigates how cultivation shifts between dune landscapes and valleys (bas-fonds) in response to climate, population pressure, and sociocultural opportunities, combining lenses rooted in land change science and the notions of double exposure and human-environmental timelines. Specifically, the interest is directed towards exploring the value of different methods of land use data harvesting.
The Sahel has been the focus of scientific interest in environmental-human dynamics and interactions. The objective of the present study is to contribute to the recent debate on the re-greening of Sahel. The paper examines the dynamics of barren land in the Sahel of Burkina Faso through analysis of remotely-sensed and rainfall data from 1975–2011. Discussions with farmers and land management staff have helped to understand the anthropogenic efforts toward soil restoration to enable the subsistence farming agriculture.
Climatic stress and anthropogenic disturbances have caused significant environmental changes in the Sahel. In this context, the importance of soil is often underrepresented. Thus, we analyze and discuss the interdependency of soil and vegetation by classifying soil types and its woody cover for a region in the Senegalese Ferlo. Clustering of 28 soil parameters led to four soil types which correspond with local Wolof denotations: Dek, Bowel, Dior and Bardial.
Crown diameter and tree density were measured in 52 communities in the Sudan-Sahel using satellite imagery to determine the relationships between rainfall and distance from community center to crown size diameter and tree density. As distance from the community center increased, tree density and crown diameter decreased. As rainfall increased, tree density decreased while crown diameter increased. Distance from the community center is a proxy for age since urbanization and our results indicate that older parts of communities show longer and more consistent tree management.

These guidelines are the result a consultative process that involved a large number of practitioners from both developed and developing countries. Two meetings were held in Glasgow and Delhi and a tentative outline was agreed upon. The guidelines are intended to provide a reference framework for decision makers and planners to adequately plan, design and manage the forest and trees in and around their cities.
This publication responds to calls in regional and global forestry forums to strengthen capacity for effectively developing and implementing payment schemes for environmental services in sub-Saharan Africa. In particular, the African Forestry and Wildlife Commission, at its 18th session, called for enhancement of the institutional capacities of member countries and the sharing of knowledge on payment schemes for forest environmental services at the national and subregional levels.
An international review of forestry and forest products
This regional evaluation is based on discussions and outputs of the consultation meeting of Francophone Africa on the Voluntary guidelines on the responsible governance of tenure of land and other natural resources that was held in Ouagadougou, Burkina Faso on 23-25 June 2010. The opinions expressed in this evaluation are those of the participants at the consultation meeting and do not necessarily reflect those of FAO.
