The sandy croplands in the Free State have been identified as one of the main dust sources in South Africa. The aim of this study was to investigate the occurrence and strength of physical soil crusts on cropland soils in the Free State, to identify the rainfall required to form a stable crust, and to test their impact on dust emissions. Crust strength was measured using a fall cone penetrometer and a torvane, while laboratory rainfall simulations were used to form experimental crusts. Dust emissions were measured with a Portable In-Situ Wind Erosion Laboratory (PI-SWERL).

The purpose of this research is to better conserve biodiversity by improving land allocation modeling software. Here we introduce a planning support framework designed to be understood by and useful to land managers, stakeholders, and other decision-makers. With understanding comes trust and engagement, which often yield better implementation of model results.

Roughly 90% of farmers in the Western Cape Province of South Africa have converted to no-tillage systems to improve the efficiency of crop production. Implementation of no-tillage restricts the mixing of soil amendments, such as limestone, into soil. Stratification of nutrients and pH is expected. A soil survey was conducted to determine the extent and geographical spread of acid soils and pH stratification throughout the Western Cape. Soil samples (n = 653) were taken at three depths (0–5, 5–15, 15–30 cm) from no-tillage fields.

What is the state of land information in South Africa? Is there really a lack of land data to support decisions and to improve land governance? This was the point of departure that a team of specialists grappled with to uncover the many different sources of land data and information available in South Africa. For the very first time, they attempted to systematically review and categorize the entire ecosystem of data and information related to key land topics in the country, assessing over 104 land datasets from 59 different sources.

The spread of COVID-19 in South Africa and other countries in the region has again brought to the fore the fact that very dense, under-serviced, mostly informal, settlements are not healthy places to live. They are also places where the spread of a disease is difficult to prevent or manage.
The kind of emergency response that was required to address the imminent spread of COVID-19 highlighted the widespread vulnerability of the poorest, compounded by highly unequal access to services and ongoing unhealthy living conditions.

Joint Ventures (JVs) between ‘agribusiness’ investors and ‘small farmers’ or ‘customary landowners’ are being promoted in South Africa’s land and agrarian reform programme as a way to include land reform beneficiaries in the country’s competitive agricultural sector. This paper undertakes an in-depth comparative analysis of two JV dairy farms located on irrigation schemes in the former ‘homeland’ of the Ciskei, in South Africa’s Eastern Cape Province. The community, through government investment, brings the fixed assets to the business: land, irrigation infrastructure and milking parlours.

This study presents an integrated examination of both the ecosystem services (ES) and ecosystem disservices (EDS) associated with smallholder animal husbandry in rural livelihoods in three villages in southeast South Africa. It recognises the contribution of ES supporting and resulting from smallholder livestock and poultry production, but also details the limiting factors or EDS, such as tick-borne disease, birds of prey or unpalatable rangeland, produced by the same system.

Protected area managers rely on relevant, credible, and legitimate knowledge. However, an increase in the rate, extent, severity, and magnitude of the impacts of drivers of change (e.g., climate change, altered land use, and demand for natural resources) is affecting the response capacity of managers and their agencies. We address temporal aspects of knowledge governance by exploring time-related characteristics of information and decision-making processes in protected areas.

United Nations Educational Scientific and Cultural Organization (UNESCO) Biosphere Reserves strive for a harmonious interaction between humans and nature. As landscapes provide suitable units to mutually address matters of conservation and sustainable development, this study aims to explore the potential and realized contribution of biosphere reserves for landscape governance and management. We emphasize the role of stakeholder participation and cooperation as an overarching condition for integrated landscape approaches.

Landscape stewardship is increasingly understood within the framing of complex social-ecological systems. To consider the implications of this, we focus on one of the key characteristics of complex social-ecological systems: they are relationally constituted, meaning that system characteristics emerge out of dynamic relations between system components. We focus on multi-actor collaboration as a key form of relationality in landscapes, seeking a more textured understanding of the social relations between landscape actors.
