UN Climate Change News, 27 April 2022 - The way land resources - soil, water and biodiversity - are currently mismanaged and misused threatens the health and continued survival of many species on Earth, including our own, warns a stark (link is external) new report from the United Nations Convention to Combat Desertification ((link is external) UNCCD).
It also points decision makers to hundreds of practical ways to effect local, national and regional land and ecosystem restoration.
The report points out that many regenerative agriculture practices have the potential to increase crop yields and improve their nutritional quality while reducing greenhouse gas emissions and drawing down carbon from the atmosphere, thereby helping to combat climate change.
UNCCD's evidence-based flagship Global Land Outlook 2 (GLO2) report, five years in development with 21 partner organizations, and with over 1,000 references, is the most comprehensive consolidation of information on the topic ever assembled.
It offers an overview of unprecedented breadth and projects the planetary consequences of three scenarios through 2050: business as usual, restoration of 50 million square km of land, and restoration measures augmented by the conservation of natural areas important for specific ecosystem functions.
It also assesses the potential contributions of land restoration investments to climate change mitigation, biodiversity conservation, poverty reduction, human health and other key sustainable development goals.
Warns the report: "At no other point in modern history has humanity faced such an array of familiar and unfamiliar risks and hazards, interacting in a hyper-connected and rapidly changing world. We cannot afford to underestimate the scale and impact of these existential threats."
"Conserving, restoring, and using our land resources sustainably is a global imperative, one that requires action on a crisis footing…Business as usual is not a viable pathway for our continued survival and prosperity.
GLO2 offers hundreds of examples from around the world that demonstrate the potential of land restoration. It is being released before the UNCCD's 15th session of the Conference of Parties to be held in Abidjan, Côte d'Ivoire (COP15, 9-20 May).
Says Ibrahim Thiaw, Executive Secretary of the UNCCD: "Modern agriculture has altered the face of the planet more than any other human activity. We need to urgently rethink our global food systems, which are responsible for 80% of deforestation, 70% of freshwater use, and the single greatest cause of terrestrial biodiversity loss."
"Investing in large-scale land restoration is a powerful, cost-effective tool to combat desertification, soil erosion, and loss of agricultural production. As a finite resource and our most valuable natural asset, we cannot afford to continue taking land for granted."
GLO2 offers hundreds of good practice snapshots from around the world that illustrate context-specific measures to combat environmental degradation, restore land health, and improve living conditions.
Examples include rewilding - reducing the human footprint to allow natural ecological processes to re-establish themselves - in the Greater Côa Valley in northern Portugal and the Iberá wetlands in Argentina; drought preparedness and risk reduction through national programmes in Mexico, the USA, and Brazil; sand and dust storm source mitigation in Iraq, China, and Kuwait; and gender-responsive land restoration in Mali, Nicauragua, and Jordan. There are also cases of integrated flood and drought strategies as well as forest landscape restoration using high-value crops.
Good practices can involve terrace and contour farming, conserving and restoring watersheds, and rainwater harvesting and storage. In addition to their economic benefits, these measures improve water retention and availability, prevent soil erosion and landslides, reduce flood risk, sequester carbon, and protect biodiversity habitat.
"The case studies from around the world showcased in GLO2 make clear that land restoration can be implemented in almost all settings and at many spatial scales, suggesting that every country can design and implement a tailored land restoration agenda to meet their development needs," says Mr. Thiaw.
Many of the cases, he adds, underscore the value of education, training, and capacity building, not just for local communities, but also for government officials, land managers, and development planners. Linking local engagement to national policies and budgets will help ensure a responsive and well-aligned restoration agenda that delivers tangible outcomes for people, nature, and the climate.
