Pastoralist knowledge and perceptions on land degradation and forage diversity loss: a case study in the Bordj Bou Arreridj semi-arid region, Algeria

Abstract

This study assessed the level of knowledge and perception of pastoralists in the Bordj Bou Arreridj zone in the semi-arid region of Algeria regarding pastureland degradation and loss of forage species diversity. Through group discussions and field surveys, 100 pastoralists were interviewed regarding the status of pasturelands (sub-steppe, scrub and forest pastures) and the effects of pastureland conditions on forage and livestock. Sixty percent of the interviewed pastoralists reported a high level of pasture degradation, and 40% had experienced this situation in the last five years. Perceived degradation is significantly related to pasture type, municipality, age and education of pastoralists. Ninety percent of the farmers noted a decrease in plant coverage and 70% reported a reduction in floristic diversity. Forty species belonging to 19 plant families have disappeared, or their floristic diversity has been reduced. Climate change and drought, as well as increasing local populations and overgrazing, are recognised as the principal causes of this situation. The current condition of pastures has significantly affected livestock (livestock prices and herd size). Local stakeholders must act quickly to manage livestock grazing and help pastoral farmers supply feed and cultivated fodder.
