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 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.

Land is the foundation of our life; stopping the critical loss of land and turning this trend around is critical for the future prosperity and security of humankind. The Sustainable Development Goal 15 “Life on land” commits world leaders to work together to achieve land degradation neutrality (LDN) for safeguarding life on land. One of the objectives that comprises LDN is to reinforce responsible governance of land tenure.

Sustainable management of the natural resource base is a fundamental issue to support global environmental benefits provided by ecosystem services, and to ensure agricultural production and ultimately food security and livelihoods. Assessing Land degradation is a major component of effective sustainable land management particularly in Small Island Developing States (SIDS).

Land is an essential building block of civilization yet its contribution to our quality of life is perceived and valued in starkly different and often incompatible ways. Conflicts about land use are intensifying in many countries. The world has reached a point where we must reconcile these differences and rethink the way in which we use and manage the land.

The desertification is described as the land degradation occurring as a result of climate change and human activities in arid, semi-arid and semi-humid areas. In today’s world, climate change, desertification, land degradation and drought are amongst the most critical issues as they affect over 4 billion hectares of land in more than 164 countries, and directly impact approximately 1.5 billion people. These hazards threaten not only the environment, but also economy, security, development, food security and social life in Turkey as well as around the globe.

Productive land is a critical natural asset for rural communities in developing nations, providing them with a wide range of ecosystem resources, such as water, fertile soils, plant and genetic diversity – on which they depend daily for survival. For many communities, the land is also an integral part of their cultural identity, helping to maintain social cohesion and stability, in addition to building resilience to socio-ecological shocks and risks such as those caused by climate change. But land is a vulnerable resource that must be managed and restored to ensure a sustainable future.

Land Degradation Neutrality is one of the Sustainable Development Goal targets, requiring on-going degradation to be balanced by restoration and sustainable land management. However, restoration and efforts to prevent degradation have often failed to deliver expected benefits, despite enormous investments. Better acknowledging the close relationships between climate, land management and non-linear ecosystem dynamics can help restoration activities to meet their intended goals, while supporting climate change adaptation and mitigation.

Pressing issues such as water and food security, health, peace, and poverty are deeply linked to land degradation. The authors use China’s major land restoration programs as a case offering perspective on the existing problems in China’s major policies for improving degraded land and maintaining land resources in three dimensions.

Land provides crucial ecosystem services for human existence and human well-being, including provisioning, regulating, supporting and cultural services. Those services provide among others the production of fresh air, food, feed, fuel and fibre. They regulate the risks of natural hazards and climate change, offer cultural and spiritual values to our society, and support key ecological functions such as nutrient and water cycling, filtering and buffering, and are central to economic vitality.

The current pressures on land are huge and expected to continue growing: there is rapidly escalating competition between the demand for land functions that provide food, water, and energy, and those services that support and regulate all life cycles on Earth.
