Almost one-quarter of the world’s land area has been degraded over the past 50 years because of soil erosion, salinization, peatland and wetland drainage, and forest degradation. The resulting damage, in terms of lost ecosystem goods and services, costs the world an estimated US$6.3 trillion a year. Almost a quarter of the world’s land area has been degraded over the past 50 years.
This is the result of soil erosion, salinization, peatland and wetland drainage, and forest degradation.

Why is it so important to restore degraded landscapes? It’s actually very simple.
We rely on healthy ecosystems to provide us with our food, water, clean air, climate stability, social and economic wealth; even our happiness and well-being. We only have to look at history to see the devastating consequences of not valuing or understanding ecosystems: whole civilizations have vanished after overexploiting their natural resources.

The Global Landscapes Forum (GLF) entered a new era in December 2017 when it successfully launched its next five-year phase, centered on building a worldwide movement to connect and engage one billion people around sustainable land use.

The inaugural meeting of this ‘new’ GLF was held from 19-20 December at the World Conference Center in Bonn, Germany, where the movement will take up residence over the next five years.

Policy reform is required to more accurately value natural capital and incentivize green investments through aligned subsidies, supportive financial measures, and risk mitigation support.

A centralized system that synthesizes evidence and connects projects to investors would both improve awareness of initiatives and funding sources, and build capacity and financial literacy.

Key information gaps persist in reporting, monitoring and impact assessment. Leveraging a centralized system could reduce redundancies, enhance cost-effectiveness and bridge finance gaps.

Landscape governance relates to how rules and decision-making address overlapping claims and conflicting interests in the landscape. It also relates to how rules and decision-making encourage synergies among stakeholders and stimulate the sustainable management of the landscape. In order to achieve sustainable landscape development, it is crucial to understand how governance processes are organized, and how this influences the decisions and behaviour of actors in the landscape.

Oil palm plantations in Indonesia have been linked to substantial deforestation in the 1990s and 2000s, though recent studies suggest that new plantations are increasingly developed on non-forest land. Without nationwide data to establish recent baseline trends, the impact of commitments to eliminate deforestation from palm oil supply chains could therefore be overestimated. We examine the area and proportion of plantations replacing forests across Sumatra, Kalimantan, and Papua up to 2015, and map biophysically suitable areas for future deforestation-free expansion.

In the last decade, there have been a number of global/regional targets and initiatives to halt and reverse land degradation and restore degraded land. Starting in 2010, these include the CBD’s Aichi Biodiversity Targets, one of which aims to restore at least 15% of degraded ecosystems; the Bonn Challenge and its regional initiatives to restore more than 150 million hectares; and most recently the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs).

The pressure on land is growing in many regions of the world, due to the increasing demand for arable crops, meat and dairy products, bio-energy and timber, and is exacerbated by land degradation and climate change. This policy report provides scenario projections for the UNCCD Global Land Outlook, exploring future changes to the use and condition of land and the resulting impacts on food, water, climate change and biodiversity.

Becoming land degradation neutral is not simply about restoring degraded lands. It is about self interest making sure the land can still provide food and fresh water for us, our children, and to the third and fourth generations. It is about giving every child, from Mongolia to Afghanistan and from Ethiopia to China, the fighting chance for a better life. If this all sounds too good to be true, read this book.

UNDP’s support to countries on sustainable land management and restoration is designed to enhance livelihoods, secure food and water, build resilience and increase carbon storage and sequestration. Drawing on over 40 years of experience and expertise, UNDP assists countries to integrate land and related environmental concerns into national and sectoral development plans and strategies, secure resources, and implement programmes that advance inclusive, sustainable growth and development.

The Great Green Wall is one of the main vehicles for delivering the Sustainable Development Goals and the Rio conventions in the Sahel. Biodiversity is the foundation of the Great Green Wall in many ways, determining soil productivity and water cycles and providing the foundation for risk management and resilient ecosystems. The Great Green Wall can make a major contribution to achieving many of the Sustainable Development Goals.

The authors briefly review how microbial biotechnology can contribute to improve activities aiming to restore degraded drylands and to combat their desertification, which are an integral part of the Sustainable Development Goal 15 of the 2030 Agenda. Microbial biotechnology offers notable promise to improve restoration actions based on the use of biocrust‐forming engineered cyanobacteria, which play key roles in maintaining ecosystem structure and functioning in drylands worldwide.
