A call to action: 20 interventions that will matter. The report’s Call to Action identifies 20 points where interventions can create transformative and accelerated progress towards multiple goals and targets in the coming decade. These targeted actions are based on the recent scientific literature analysing the deeper systemic interconnections that identify synergies and trade-offs between individual goals and targets. Decisions based on science. Science must play a major role in advancing sustainable development.

Countries have publicly announced their commitments to restore degraded forests and lands.This report comes at a time when many countries are fully engaged in the challenging task of implementing their LDN targets and Bonn Challenge pledges with a goal to achieve them by 2030.

This UNCCD-SPI technical report provides well-established scientific evidence for understanding the strong linkages between land use and drought and how management of both is connected through water use. It introduces a new concept of Drought-smart land management (D-SLM) and organizes relevant approaches and practices in fourteen groups across four major classes of land use.

Monitoring progress towards the 2030 Development Agenda requires the combination of traditional and new data sources in innovative workflows to maximize the generation of relevant information. We present the results of a participatory and data-driven land degradation assessment process at a national scale, which includes use of earth observation (EO) data, cloud computing, and expert knowledge for Argentina.

The challenge of land degradation Sustainable land use is closely connected with many sustainable development objectives Land Degradation Neutrality (LDN).  It is estimated that two billion hectares of land is degraded worldwide, and we continue to degrade another 12 million hectares of productive land every year. According to the 2018 World Atlas of Desertification produced by the European Commission’s Joint Research Centre, 75% of the Earth’s land area is already degraded, and over 90% could become degraded by 2050.

When the UN Convention to Combat Desertification was created at the Rio Earth Summit over 25 years ago, it became the only international convention dedicated to protecting, managing and restoring our land. The environmental benefits of that work are already well documented, particularly when it comes to the inextricablelinks with climate change and biodiversity. But this book goes much further by highlighting the impact on the wellbeing of over three billion people – nearly half the world’s population – who are directly affected by land degradation.

Land restoration has tremendous potential to help the world limit climate change and achieve its aims for sustainable development. In its latest study, the International Resource Panel finds positive spin-offs to support all 17 Sustainable Development Goals agreed to by the world’s nations as part of the 2030 Agenda for Sustainable Development. While other reports have focused on a subset of the SDGs, this report has intentionally considered all of them, and has done so by inviting a large number of diverse authors to participate in the process.

The UNCCD-SPI technical report “Realising the Carbon Benefits of Sustainable Land Management Practices: Guidelines for Estimation of Soil Organic Carbon in the Context of Land Degradation” provides decision guidance for the estimation of soil organic carbon (SOC) in support of appropriate deployment of sustainable land management (SLM) technologies, in order to maintain or increase carbon in the soil and contribute to the achievement of land degradation neutrality (LDN).

Land degradation exacerbates the unique vulnerabilities of Small Island Developing States (SIDS) to environmental challenges, such as climate change, flash floods, soil erosion, lagoon siltation, coastal erosion and sea level rise, undermining their economic potential. Land Degradation Neutrality (LDN) contributes to achieving the Sustainable Development Goals (SDGs) in SIDS, preserving biodiversity and increasing resilience to climate change. Land degradation has a strong negative impact on climate-sensitive sectors like agriculture, water resources management and coastal zone management.

Numbers can tell a compelling story. In this brochure, the numbers highlight how much we rely on productive land. Amongst other valuable services, land feeds our families, provides fresh water and powers our future ambitions. Much of the data collected here, however, demonstrate how close we are to pushing our relationship with the land to breaking point. The magnitude of the challenges and potential consequences of failing to implement bold action on land and soil, in terms of future social stability and economic development, should not be underestimated.

Land degradation neutrality (LDN) is achieved if land degradation is avoided or reduced, and new degradation is balanced by reversing degradation elsewhere in the same land type through restoration or rehabilitation. The primary instrument for avoiding and reducing degradation is the application of sustainable land management (SLM) approaches and technologies. Because of its multifunctional roles and its sensitivity to land management, soil organic carbon (SOC) is one of the three global indicators for LDN, so predicting and monitoring change in SOC is vital to achieving LDN targets.

Located in the arid and semi-arid areas of West Africa, the Sahel has undergone profound changes over the past 50 years. Known for the prevalence of land degradation processes, the Sahel is suffering from the combined negative effects of population growth, human activities and climate variability, resulting in recurrent droughts and the continued decline of natural resources and land productivity.
