Livestock is poorly represented in N budgets for the African continent although some studies have examined livestock-related N flows at different levels. Livestock plays an important role in N cycling and therefore on N budgets including livestock-related flows. This study reviews the literature on N budgets for Africa to identify factors contributing to uncertainties. Livestock densities are usually modelled because of the lack of observational spatial data.

The authors started the discussion with the fundamental question: why are property rights important? The central hypothesis of this collaborative venture is that inappropriate property rights institutions lead to resource degradation. Two cases were distinguished: single-user resources and multiple-use resources. A good example of a single-user resource is land. Absence of secure property rights will result in land degradation, as incentives to improve the resource base do not exist under such conditions.

There is an increasing interest among researchers, practitioners and donors in using agricultural innovation system approaches to reach development outcomes. Limited practical experiences have been shared on the dynamics of these innovation processes and how project partners have dealt with that. The objective of this paper is therefore to share experiences from a smallholder livestock development project – the imGoats project in Mozambique – by reflecting on the dynamics of innovation processes in the project.

Restoration interventions to combat land degradation are carried out in arid and semi-arid areas to improve vegetation cover and land productivity. Evaluating the success of an intervention over time is challenging due to various constraints (e.g. difficult-to-access areas, lack of long-term records) and the lack of standardised and affordable methodologies. We propose a semi-automatic methodology that uses remote sensing data to provide a rapid, standardised and objective assessment of the biophysical impact, in terms of vegetation cover, of restoration interventions.
