Managing rangelands: promoting and establishing sand dune fixing species: Stipagrostis pungens (Desf.) De Winter: a xerophytic quicksand- and dune-fixing species adapted to sandy deserts
Stipagrostis pungens is a perennial grass species which belongs to the Poaceae family. It is usually found with several erect culms, grows up to 1.5 m in height, and forms substantial tufts. It is a tall stiff glabrous grass with pungent leaves, and a C4 grass with sclerophyllous, spine-tipped, inrolled leaves, with sunken stomata. The root system extends laterally for a radius of 20 m or more. The roots are covered throughout their length by a sandy sheath, which is penetrated by the root hairs that occur throughout the entire length of the sheath.
Coupling land-use change and hydrologic models for quantification of catchment ecosystem services
Representation of land-use and hydrologic interactions in respective models has traditionally been problematic. The use of static land-use in most hydrologic models or that of the use of simple hydrologic proxies in land-use change models call for more integrated approaches. The objective of this study is to assess whether dynamic feedback between land-use change and hydrology can (1) improve model performances, and/or (2) produce a more realistic quantification of ecosystem services. To test this, we coupled a land-use change model and a hydrologic mode.

Making Rangelands More Secure
The topic of how best to make rangelands secure for local rangeland users is one of ongoing debates. The very nature of rangeland use – the need for landscape level planning incorporating spatially and temporally variable resources, and for recognising the multiple layers of use by multiple actors presents complexity that is not easily accounted for by the often inflexible and simpler land tenure systems that governments prefer to introduce.
Pastoralism and Security in West Africa and the Sahel
Why this study?
Recent years have witnessed an increase in violent conflicts involving pastoralists in parts of West Africa and the Sahel. They often take the form of clashes between herders and farmers, impacting human, national and regional security.
Given its mandate and role in conflict prevention, the United Nations Office for West Africa and the Sahel, in collaboration with the Economic Community of West African States, initiated this study in 2017 to examine the causes and identify concrete solutions to conflicts related to pastoralism.
