Land Degradation in Southern Africa: Restoration Strategies, Grazing Management, and Livelihoods

Abstract

Land degradation in communal rangelands poses significant challenges to environmental sustainability, agricultural productivity, and livelihoods in southern Africa. This study presents a bibliometric analysis of research trends, key contributors, thematic evolution, and collaborative networks in the field of land degradation in communal rangelands from 1997 to 2024. Utilizing data obtained from the Scopus database, we examined 66 publications to identify patterns in publication output, leading journals, influential articles, and prominent authors and institutions. The analysis demonstrates an overall increase in research output, with a notable surge in publications during the past decade, indicating a growing academic and policy interest in this field. Major themes identified include sustainable land management, restoration strategies, and the impacts of grazing management on ecosystem health. Networks showcasing co-authorship and keyword co-occurrence reveal robust collaborative connections among researchers and a concentrated focus on specific dominant themes. Consequently, these findings propose opportunities for expanding interdisciplinary research and exploring underrepresented areas. This study provides a comprehensive overview of the research landscape, offering insights to steer future studies and inform policy interventions aimed at mitigating land degradation and bolstering the resilience of communal rangelands in southern Africa.
