World's soils are under threat

Abstract: . The Intergovernmental Technical Panel on Soils has completed the first State of the World's Soil Resources Report. Globally soil erosion was identified as the gravest threat, leading to deteriorating water quality in developed regions and to lowering of crop yields in many developing regions. We need to increase nitrogen and phosphorus fertilizer use in infertile tropical and semi-tropical soils – the regions where the most food insecurity among us are found – while reducing global use of these products overall. Stores of soil organic carbon are critical in the global carbon balance, and national governments must set specific targets to stabilize or ideally increase soil organic carbon stores. Finally the quality of soil information available for policy formulation must be improved – the regional assessments in the State of the World's Soil Resources Report frequently base their evaluations on studies from the 1990s based on observations made in the 1980s or earlier.

Global governance of soil resources as a necessary condition for sustainable development

TL;DR: A new Global Soil Partnership (GSP) was proposed by the FAO and the EU in this article to ensure the necessary availability of soil resources for both current and future generations.

No silver bullet for digital soil mapping: country-specific soil organic carbon estimates across Latin America

TL;DR: In this paper, the authors identified country-specific predictors for soil organic carbon (SOC) and tested the performance of five predictive algorithms for mapping SOC across Latin America, including support vector machines, random forests, kernel-weighted nearest neighbors (KK), partial least squares regression (PL), and regression kriging based on stepwise multiple linear models (RK).

Voluntary Guidelines for Sustainable Soil Management: Global Action for Healthy Soils

TL;DR: The Voluntary Guidelines for Sustainable Soil Management (VGSSM) were developed by the Global Soil Partnership (GSP) and adopted by FAO and its member countries as mentioned in this paper.
