South boasts of more than 20 000 plant species; we have spectacular landscapes, and a scientific community committed to conserving our environment for current and future generations. Our botanical wealth is a rich source of medicines, and together with a strong agricultural sector, research in these fields has an exciting future.
In contrast, the country discontinuities in the actual rate of erosion are large: around 1.4 t ha −1 yr −1 on all land and 1.8 t ha −1 yr −1 on cropland. These values reflect the ...
The beginning of resource inventories, which was the dominant research in many countries, is dated back in the early twentieth century; some countries started with systematic survey, some with reconnaissance studies, and others produced general information with local observation. The 1970s FAO-UNESCO volume VI was the first ever official map of soils with ...
Soils and their management are fundamental to a range of essential ecosystems, societal and climate challenges facing humanity. , 25-30% of agricultural soils are considered degr aded ...

is defined as a set of fertility management practices that necessarily include the use of fertilizer, organic inputs, and improved germplasm combined with the knowledge on how to adapt these practices to local conditions, aiming at maximizing agronomic use efficiency of the applied nutrients and improving crop productivity (Vanlauwe et al. 2010 ...
The erodibility dataset overcomes the problems of limited data availability for assessment and presents a high quality resource for modellers who aim at erosion estimation on local/regional, national or scale. The new proposed dataset has also been verified against local/regional/national studies with very good results.

The Partnership (AfSP) was established in May 2015. It is composed of the Sub-Saharan countries. soils are very diverse and have great potential and value for food security and overall sustainable development. However, degradation is a serious process that is threatening the region’s resources through its ...

By contrast, forestland and other semi-natural vegetation areas experience an overall surplus of sediments which is driven by a re-deposition of sediments eroded from agricultural land. Combining the predicted loss rates with the organic carbon (SOC) stock, we estimate a SOC displacement by water erosion of 14.5 Tg yr −1.
The most common engineering classification system for soils in North America is the Unified System (USCS). The USCS has three major classification groups: (1) coarse-grained soils (e.g. sands and gravels ); (2) fine-grained soils (e.g. silts and clays ); and (3) highly organic soils (referred to as "peat").
