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.
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.
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.
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 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.
Funding from the voluntary carbon market (VCM) can help to restore productive landscapes, if it is embedded in the local context of traditions and in state governance systems. Restoration efforts under a performance-based VCM programme, if planned well, can also improve livelihoods.
Federal investments in ecosystem restoration projects protect Federal trusts, ensure public health and safety, and preserve and enhance essential ecosystem services. These investments also generate business activity and create jobs.
The review was conducted with the aim to provide guidance for future engagement / investments, in particular in the context of recent AU declarations on agriculture and on land restoration by NEPAD, GEF, TerrAfrica, the Great Green Wall Initiative for the Sahel and Sahara (GGWISS), UN agencies and other donors.
Land is of multi-dimensional character. It is multi-scale, multi-functional, multi-sectorial, multi-actor based: it needs people from practice and research to interact as equal partners to make sense of research for sustainable land management. The kind of research needed to deal with this complexity and these challenges we term implementation-oriented research.
Land take, or the change from non-artificial to artificial land cover, reflects on-going and often conflicting claims on land. Some of the land that is 'taken' for urban development is covered with an impervious surface, which severely hampers ecosystem functioning and the related delivery of ecosystem services.
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.
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.
