An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
As more frequent droughts and floods threaten the global food supply, humans are increasing their demands on water and land,... The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.

Le cadre conceptuel scientifique pour la neutralité de la dégradation des terres (LDN) fournit une base scientifique pour comprendre, mettre en œuvre et surveiller la LDN. Il a été conçu pour créer un pont entre la vision et la mise en œuvre pratique de la NCD, en définissant la NCD en term...es opérationnels. Le cadre conceptuel est un produit de l'interface science-politique de la CCD.

El marco conceptual científico de la neutralidad de la degradación de la tierra (LDR) proporciona una base científica para comprender, aplicar y supervisar la LDR. Su objetivo es salvar la brecha entre la visión y la aplicación práctica de la ENC, definiendo la ENC en términos operativos. El ...marco conceptual es un producto de la interfaz ciencia-política de la CNULD.

Human use of land has been transforming Earth's ecology for millennia. From hunting and foraging to burning the land to farming to industrial agriculture, increasingly intensive human use of land has reshaped global patterns of biodiversity, ecosystems, landscapes, and climate. This review examines ...recent evidence from archaeology, paleoecology, environmental history, and model-based reconstructions that reveal a planet largely transformed by land use over more than 10,000 years. Although land use has always sustained human societies, its ecological consequences are diverse and sometimes opposing, both degrading and enriching soils, shrinking wild habitats and shaping novel ones, causing extinctions of some species while propagating and domesticating others, and both emitting and absorbing the greenhouse gases that cause global climate change. By transforming Earth's ecology, land use has literally paved the way for the Anthropocene.

The Scientific Conceptual Framework for Land Degradation Neutrality (LDN) provides a scientific foundation for understanding, implementing and monitoring LDN. It has been designed to create a bridge between the vision and the practical implementation of LDN, by defining LDN in operational terms. The... conceptual framework is a product of the UNCCD Science-Policy Interface.

We use soils to provide 98.8% of our food, but we must ensure that the pressure we place on soils to provide this food in the short-term does not inadvertently push the Earth into a less hospitable state in the long-term. Using the planeta...ry boundaries framework, we show that soils are a master variable for regulating critical Earth-system processes. Indeed, of the seven Earth-systems that have been quantified, soils play a critical and substantial role in changing the Earth-systems in at least two, either directly or indirectly, as well as smaller contributions for a further three.
