Road to Ankara and to a Land Degradation Neutral World

Reports & Research
Noviembre, 2015
Global

The World Business Council for Sustainable Development has developed a comprehensive work program that can help its members better understand risks linked to inaction and opportunities for action, structuring its work program around the international discussions led by the UNCCD on LDN. In particular LDN is reflected in the WBCSD’s Action2020 targets of “restoring at least 12 million hectares per year of degraded land”, and a business solution on “Restoring Degraded Land” has been developed to provide a response to land degradation challenges and the LDN target.

Drylands occupy more than 40% of the world’s land area and are home to some two billion people. This includes a disproportionate number of the world’s poorest people, who live in degraded and severely degraded landscapes. The United Nations Convention to Combat Desertification states on its website that 12 million hectares are lost annually to desertification and drought, and that more than 1.5 billion people are directly dependent on land that is being degraded, leading to US$42 billion in lost earnings each year.

Regreening Africa: A bottom-up transformation of degraded lands

Reports & Research

África

It is estimated that 20% of global land is either degraded or undergoing degradation, leading to an annual loss of 12 million hectares of productive land (UNCCD 2017). In Africa, some 715 million ha are degraded, including 65% of all arable land, 30% of all grazing land and 20% of all forests. This is due to increasing populations, poor land management, institutional challenges and climate change (Gnacadja and Wiese 2016).

This study develops options for the German government to improve international soil governance in the short, medium and long term. The study first takes stock of existing international instruments and institutions that are relevant for soil protection and its governance at the international level. It as-sesses the actual and potential steering effect of, inter alia, the Desertification Convention, the Biodiversity Convention, the Paris Agreement and climate regime, regional treaties, FAO, UNEP, IPBES and IPCC.

Guidance for using the IUCN Global Standard for Nature-based Solutions: a user-friendly framework for the verification, design and scaling up of Nature-based Solutions: first edition

IUCN unveiled a Global Standard providing the first-ever set of benchmarks for nature-based solutions to global challenges. The new IUCN Global Standard will help governments, business and civil society ensure the effectiveness of nature-based solutions and maximise their potential to help address climate change, biodiversity loss and other societal challenges on a global scale. The world is looking for durable and effective options to tackle global challenges such as climate change, food and water security, and now, economic recovery from the global pandemic.

Progress Towards the SDG Land Degradation and Restoration Commitments

Global

Since the commitments and reporting requirements of the SDGs ov erlap significantly with those of the UNFCCC and UNCCD, policy designe rs have mutually reinforcing incentives to advance this SDG commitment. When env ironmental degradation is minimized and restoration efforts are prioritized , ecosystems can sequester and store more carbon and lessen the impact of some c limate change effects.

Land degradation neutrality ( in The Mediterranean region under climate change : a scientific update)

This chapter sets out to present a short review of (i) the general context of land degradation under the framework of UNCCD – the international convention on desertification with a specific focus on Land Degradation Neutrality, and (ii) examples of the main processes responsible for soil degradation (e.g. surface crusting, runoff and water erosion, tillage erosion, wind erosion, and salinization), along with the principles of desertification control and land rehabilitation, in light of the socioeconomic context and ecological conditions and processes.

Caring for soil is caring for life. Ensure 75% of soils are healthy by 2030 for healthy food, people, nature and climate : interim report of the mission board for soil health and food

Life on Earth depends on healthy soils. The soil under our feet is a living system – home to many fascinating plants and animals, whose invisible interactions ensure our well-being and that of the planet. Soils provide us with nutritious food and other products as well as with clean water and flourishing habitats for biodiversity. At the same time, soils can help slow the onset of climate change and make us more resilient to extreme climate events such as droughts and floods. Soils preserve our cultural heritage and are a key part of the landscapes that we all cherish.

Life on land: Why it matters

Global

What’s the goal here? To sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss. Two billion hectares of land on Earth are degraded, affecting some 3.2 billion people, driving species to extinction and intensifying climate change. Goal 15: Life on land Human life depends on the earth as much as the ocean for our sustenance and livelihoods. Plant life provides 80 percent of the human diet, and we rely on agriculture as an important economic resources.

Land degradation states and trends in the northwestern Maghreb drylands, 1998–2008

States of ecological maturity and temporal trends of drylands in Morocco, Algeria and Tunisia north of 28 N are reported for 1998–2008. The input data were Normalized Difference Vegetation Index databases and corresponding climate fields, at a spatial resolution of 1 km and a temporal resolution of one month. States convey opposing dynamics of human exploitation and ecological succession. They were identified synchronically for the full period by comparing each location to all other locations in the study area under equivalent aridity.

The Lawra district of the Upper West region was selected as the case study. This study compared crop yields for FMNR and non-FMNR farmers. FMNR farmers are classified as having at least 8 trees per acre, with an average of 13 trees per acre (33 per ha) and a maximum of 40. Non-FMNR farmers are classified as having between 1 and 7 trees per acre, with an average of 5.Qualitative (focus group discussion) and quantitative (household survey) data were collected in April to May 2019. Over 500 households were interviewed in both CIKOD intervention communities and control sites.

Nature loss is a planetary emergency. Humanity has already wiped out 83% of wild mammals and half of all plants and severely altered three-quarters of ice-free land and two-thirds of marine environments. One million species are at risk of extinction in the coming decades – a rate tens to hundreds of times higher than the average over the past 10 million years. The World Economic Forum’s 2020 Global Risks Report ranks biodiversity loss and ecosystem collapse as one of the top five threats humanity will face in the next ten years.
