Vegetation dynamics in rangelands and other ecosystems are known to be mediated by topoedaphic properties. Vegetation monitoring programs, however, often do not consider the impact of soils and other sources of landscape heterogeneity on the temporal patterns observed.
BACKGROUND AND AIMS: Grazing lands worldwide are increasingly subjected to intensification to meet global demand for food; however, management practices intended to increase production can also affect ecosystem carbon (C) stocks.
Reports of positive or neutral effects of grazing on plant species richness have prompted calls for livestock grazing to be used as a tool for managing land for conservation.
The need to maintain or increase livestock mobility in arid Africa has been widely embraced by ecologists, social scientists, and more recently regional governments. These movements are seen to sustain livestock production under a highly variable and changing climate.
The limited amount of studies addressing the long‐term effectiveness of restoration actions to combat land degradation is a constraint for current landscape restoration planning and implementation.
Reconciling the well known benefits of shrubs for forage with environmental goals, whilst preventing their dominance, is a major challenge in rangeland management. Browsing may be an economical solution for shrubby rangelands as herbivore browsing has been shown to control juvenile shrub growth.
Desert rangelands are characterised by low and highly variable rainfall regime, low forage production and high heterogeneity in the distribution of natural resources.
An International Conference was held in Rome, Italy 27-29 April 2015 to launch the IFAD and EU supported Project ‘Linking agrobiodiversity value chains, climate adaptation and nutrition: Empowering the poor to manage risk’.
