Restoration has never been more important, with almost a third of the world’s land surface degraded. But what exactly is restoration? And how do we know if it works?

 

More than 1.5 billion of the world’s poorest people are directly affected ...

Working with nature: tropical
forest regrowth and its potential for mitigating climate change

The Bonn challenge aims to restore 350 million hectares of
degraded land by 2030 of which currently almost 100 million hectares has been
committed through various initiatives. Restoration is a global priority; not
only to restore the productivity of degraded and unproductive ...

The Land Degradation Surveillance Framework (LDSF)

Key facts

The Land Degradation Surveillance Framework (LDSF) was developed as a response to a lack of methods for systematic landscape-level assessment of soil and ecosystem health. The methodology is designed to provide a biophysical baseline at landscape level, and a monitoring and evaluation framework for assessing processes of land degradation and the effectiveness of ...

Mapping the source of soil erosion

Predicting soil erosion

Conventional soil erosion models are generally based on the Universal Soil Loss Equation (USLE), or a revised (RUSLE) or modified (Williams and Berndt (1977)) version of the USLE. Betrie et al (2011) used the Soil and Water Assessment Tool (SWAT), which uses MUSLE to compute soil erosion, to model sediment transport in ...

Land cover change in the Virunga landscape

Last update on Feb. 24, 2014.

The Virunga landscape has one of the greatest diversities of habitats globally within about 790 thousand hectares. Thousands of hippopotamuses and elephants live in the park's rivers and its mountains are a critical area for the survival of the mountain and lowland gorillas. However, these habitats have undergone dramatic changes in land cover and ...

Maps of soil functional properties for Africa

Last update on March 19, 2014.

The Land Degradation Surveillance Framework (LDSF) was developed at the World Agroforestry Centre for landscape level assessments and studies of carbon dynamics, vegetation changes, soil functional properties and soil hydrological properties. The LDSF has been implemented in more than 20 countries in Africa to date, including the CIAT-led [Africa Soil Information Service (AfSIS)]("http://worldagroforestry ...
