Soil organic carbon (SOC) prediction from remote sensing is often hindered by disturbing factors at the soil surface, such as photosynthetic active and non–photosynthetic active vegetation, variation in soil moisture or surface roughness. With the increasing amount of freely available satellite data, …

Artists and other cultural workers have tried to create stable, long-term collective income systems for themselves forever. In 2004, an American tech entrepreneur launched one of the most ambitious redistribution schemes up to date, the Artist Pension Trust (APT). The idea was to give artists not just …

As a student of industrial product design I have gotten used to making and fixing everything myself. If I run into a problem or a product breaks, I try to solve and repair it. If I couldn’t do it yet, I'd just learn how to. This led me to build my own house on wheels at the start of 2020. The complete …

Diadema sea-urchins play a vital role in maintaining a balanced coral reef ecosystem by grazing away algae and creating bare substrate for coral recruitment. The RAAKPRO Diadema project aims to develop interventions to improve larval recruitment and juvenile survival to increase local Diadema populations. …

In this study, we compared the early fish colonization of three types of artificial reefs deployed in the coastal waters of Saba and St Eustatius in the Caribbean: reef balls®, layered cakes and piles of locally obtained basaltic rock. As an indicator of performance, three fish assemblage parameters …

In 1990, livestock grazing was introduced in Meijendel, a 1800 ha lime-rich coastal dune area, at a density of 0.06–0.07 LLU.ha-1.year−1 (1:12–18 ha) to counteract encroachment of tall grasses and shrubland on dune grassland and increase the bare sand area. Monitoring was based on four digital orthophotos …

The Compassberg Protected Environment (CPE) in South-Africa suffers severely from erosion in the form of gullies. Herbivory, bare soil, little water capture and lack of vegetation are the most important factors that contribute to erosion in the CPE. Grazing lawns are a vegetation type that is only found …
