Abstract

Soil degradation is globally concerning due to its adverse effects on the environment and agricultural production. Much of Swaziland is at risk from degradation. This paper assesses farmer perceptions and responses to soil degradation in 2002 and 2014, focusing on two land uses that underpin rural livelihoods: arable land and rangeland areas. It uses repeat household surveys and semi‐structured interviews, in two case study chiefdoms in the country's middleveld (KaBhudla and Engcayini) in the first longitudinal study of its kind. We find that observations of land degradation are perceived mainly through changes in land productivity, with chemical degradation occurring predominantly on arable land and physical degradation and erosion mainly in rangeland areas. Changes in rainfall are particularly important in determining responses. While perceptions of the causes and impacts of degradation largely concur with the scientific literature, responses were constrained by poor land availability, shorter and more unpredictable cropping seasons because of changing rains and low awareness, access to or knowledge of agricultural inputs. We suggest that sustainable arable land management can be enhanced through improved access to alternative sources of water, use of management practices that retain soil and moisture and greater access to agricultural inputs and capacity building to ensure their appropriate use. We suggest collaborative management for settlement planning that integrates soil conservation and livestock management strategies such as controlled stocking levels and rotational grazing could improve land quality in rangeland areas. Together, these approaches can help land users to better manage change. © 2016 The Authors. Land Degradation & Development published by John Wiley & Sons Ltd.

Highlights

  • Land degradation can be defined as a persistent deterioration of land’s productivity and often focuses on the soil component (Adeel et al, 2005)

  • Increased variability in annual yields was mainly attributed to changes in the use of agricultural inputs

  • South Africa suggests that greater population densities correlate with higher levels of vegetation and reduced erosion (Kiage, 2013), our results show the opposite

Summary

Introduction

Land degradation can be defined as a persistent deterioration of land’s productivity and often focuses on the soil component (Adeel et al, 2005). Degradation is caused by multiple factors, both biophysical (e.g. climate, topography, hydrology and soil characteristics) and human (e.g. land use and management, policies and governance, migration, poverty and natural resource exploitation). These factors interact over multiple spatial and temporal scales (Kiage, 2013). Processes of land degradation have been observed across the globe, including in South America (Torres et al, 2015), Asia (Xie et al, 2015) and Africa (Stringer & Dougill, 2013).
