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.
We are in the Anthropocene. For millennia, human actions have been shaping the world to the degree that they are inscribed in the geological and ecological record. Recently, this has been occurring with increasing speed and influence. This means we need to be asking integrative and effective questions about the world and how we relate to and in it. Human niche construction has broad and deep effects not just on landscapes and environments, but on the myriad of other beings sharing space with us.
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.
In many Sub-Saharan African countries, fuelwood collection is among the most important drivers of deforestation and particularly forest degradation. In a detailed field study in the Kafa region of southern Ethiopia, we assessed the potential of efficient cooking stoves to mitigate the negative impacts of fuelwood harvesting on forests. Eleven thousand improved cooking stoves (ICS), specifically designed for baking Ethiopia’s staple food injera, referred to locally as “Mirt” stoves, have been distributed here. We found a high acceptance rate of the stove.
Land is a cross-cutting theme in most contemporary development challenges. Contemporary literature shows that land governance benefits the broader administration and governance of society. Tools enabling evaluation of land governance, however, are often focuses on national or supranational levels. Ethiopia provides a case in point: rapid urbanization and urban poverty are an issue; however, limited studies assess urban land governance from a multi-stakeholder perspective. Citizens and government representatives at different levels are the sources of information.
Large scale land acquisition is a buzzword of the day in the world, more so in Ethiopia. The issue is indeed polarizing, in one hand it is dubbed as land grab and seen as ultimate scramble for land. On the other hand, it is often depicted as key to development, technology transfer and boost in productivity of an otherwise idle land available in Ethiopian lowlands, or somewhere else.
Peri-urban areas in Ethiopia like that of other African countries are places where much of urban growth is taking place and as a result the competition for land between agriculture and nonagriculture (urban built-up property) is intense. It is there that new properties and property rights emerge and at the same time the existing traditional or customary rights may also disappear or dissolve. This study has attempted to assess and demonstrate the process of built-up property formation process in the transitional peri-urban areas of Ethiopia.
