Displaying 6 - 10 of 10Functional diversity enhances the resistance of ecosystem multifunctionality to aridity in Mediterranean drylands
We used a functional trait‐based approach to assess the impacts of aridity and shrub encroachment on the functional structure of Mediterranean dryland communities (functional diversity (FD) and community‐weighted mean trait values (CWM)), and to evaluate how these functional attributes ultimately affect multifunctionality (i.e. the provision of several ecosystem functions simultaneously). Shrub encroachment (the increase in the abundance/cover of shrubs) is a major land cover change that is taking place in grasslands worldwide.

Rural Agricultural Livelihood Survey
The Rural Agricultural Livelihood Survey (RALS) is a new panel survey designed to obtain a comprehensive picture of Zambia’s small- and medium-scale farming sector using the 2010 census sampling frame. An earlier household panel survey for rural Zambia was the Supplemental Surveys (SS) of 2001, 2004 and 2008, which enabled the publication of a large set of important research outputs by IAPRI, Michigan State University and a range of Zambian and international partner organizations.
Indigenous flora conservation in Kenya.
This paper describes the environmental degradation that has occurred in Kenya since early this century, initially due to the introduction of plantation farming. Forests have been further targeted for farmland, fuel wood, building materials and hardwood species. Range land species have also become threatened due to continued infiltration of the population. The discussion considers the efforts of the Kenyan government to legislate and administrate against the further loss of natural resources and the consequent development of environmental awareness among the populace.
