The Economic Community of West African States (ECOWAS) recognises transhumance pastoralism as a beneficial livestock production system that can contribute to food security together with economic and political stability. Thus, the subregional bloc put together the ECOWAS Protocol on Transhumance and supporting regulations to actualise these benefits. These policies seek to regulate transhumance pastoralism

The persistent spread of shrublands is a global phenomenon observed across semiarid grassland-shrubland boundaries. Observations in South Africa, however, have detected a contrasting trend of increasing grass cover across the transition between the Nama-Karoo and Grassland Biomes over the last few decades. A west-to-east gradient of increasing mean annual rainfall, and underlying geology, controls

Knowledge about how pastoralism and kraaling may contribute to desired global objectives, such as soil fertility, is in danger of being lost. We tested whether short duration kraaling increases soil fertility across various biomes and countries via a meta-analysis (random effects model, n = 12 studies).

Implications of the breakdown in the indigenous knowledge system for rangeland management and policy: a case study from the Eastern Cape in South Africa African J. Range Forage Sci. (IF 1.4) Pub Date : 2023-02-27 Andiswa Finca, Suzanne Linnane, Jill Slinger, David Getty, M Igshaan Samuels
Communal rangelands in South Africa are generally perceived as overgrazed owing to complexities in their histories and collective utilisation which often leads to improper management. A suitable solution has not been found in land management policies because local people’s contexts and their indigenous knowledge are ignored. Hence, this paper is aimed at (i) assessing the role indigenous knowledge

Spatial variability of herbage yield, grazing capacity and plant diversity in a tropical savannah rangeland ecosystem African J. Range Forage Sci. (IF 1.4) Pub Date : 2023-02-27 ND Anane, R Ayizanga, FO Sarkwa, T Ansah, EC Timpong-Jones
To improve ruminant livestock production, evaluation of rangelands must be a routine. Rangeland evaluation gives information about the vegetation structure, biomass yield and quality. The Guinea savannah rangelands of Ghana lack research that characterises the spatial variability of herbage yield and quality. It was hypothesised that there is spatial heterogeneity in herbage yield, grazing capacity

There is a general perception that ruminants produce large quantities of greenhouse gases (GHG) which contribute to global warming. Ruminant production is also known as the world’s largest user of land, and southern Africa is no exception. Recent estimates indicate that livestock are responsible for approximately 4% of the world’s GHG emissions through methane production, compared with an initial estimate
