Fuel for Life: Securing the land - energy nexus

Journal Articles & Books
Novembro, 2015
Global

Energy is central to nearly every major challenge and opportunity the world faces today. Be it for jobs, security, climate change, food production or increasing incomes, access to energy for all is essential. Sustainable energy is an opportunity too as it fuels lives, economies and the planet. Getting sustainable energy to all who want it represents one of the biggest development challenges of the 21st century.

Sustainable rangeland management in Sub-Saharan Africa - Guidelines to good practice

Journal Articles & Books
Dezembro, 2019
Global

In Sub-Saharan Africa, the popular perception of rangelands and their management is that these vast areas have major problems without solutions: the common narrative focuses on overgrazing, herds of undernourished livestock, erosion and desertification, drought, famine, and conflict.

However, evidence compiled and analysed in this book show that such a view of rangelands – as being unproductive and mismanaged systems – does not reflect reality. It needs reconsideration and revision.

2019 Land for Life Award: Decades of Impact

The 2019 edition of the Land for Life Award puts the spotlight on individuals and organizations that made outstanding contributions to achieve land degradation neutrality on a large scale, with long-term changes and dedicated actions for 25 years or longer. Those remarkable projects involve local people, communities and the society, raising the level of their ambition. Meanwhile, recent assessments remind us that two billion hectares of land are now degraded worldwide. This represents an area larger than the territory of the Russian Federation, the biggest country in the world.

Land Degradation Neutrality : Resilience at local, national and regional levels

Journal Articles & Books

Global

Land degradation refers to any reduction or loss in the biological or economic productive capacity of the land resource base. It is generally caused by human activities, exacerbated by natural processes, and often magnified by and closely intertwined with climate change and biodiversity loss. SLM practices include the integrated management of crops (trees), livestock, soil, water, nutrients, biodiversity, disease and pests to optimize the delivery of a range of ecosystem services. The overall objective is to maximize provisioning services (e.g.

Tools for Soil Organic Carbon Estimation and Management Science-Policy Brief

Land degradation neutrality (LDN) is achieved if land degradation is avoided or reduced, and new degradation is balanced by reversing degradation elsewhere in the same land type through restoration or rehabilitation. The primary instrument for avoiding and reducing degradation is the application of sustainable land management (SLM) approaches and technologies. Because of its multifunctional roles and its sensitivity to land management, soil organic carbon (SOC) is one of the three global indicators for LDN, so predicting and monitoring change in SOC is vital to achieving LDN targets.

Desire for Greener Land. Options for Sustainable Land Management in Drylands

Journal Articles & Books
Dezembro, 2012
Global

Humankind currently faces interconnected, worldwide challenges of feeding our rapidly growing population while simultaneously preserving our natural resource base, adapting to climate change, and creating or maintaining favourable living conditions for present and future generations. The world’s population is growing exponentially. It is expected to rise from seven to more than nine billion people in the next few decades.

Land Degradation Neutrality Fund : An Innovative Investment Fund Project

Global

Two billion hectares of productive land are degraded worldwide. This is an area larger than South America or twice the size of China, and 500 million hectares of this is abandoned agricultural land. We continue to degrade another 12 million hectares of productive land every year. We need to break this destructive cycle because the benefits of preventing land degradation and reversing it are far greater than the gains from degrading new land year after year.

Realising the Carbon Benefits of Sustainable Land Management Practices. Guidelines for estimation of soil organic carbon in the context of land degradation neutrality planning and monitoring. A report of the Science-Policy Interface

The UNCCD-SPI technical report “Realising the Carbon Benefits of Sustainable Land Management Practices: Guidelines for Estimation of Soil Organic Carbon in the Context of Land Degradation” provides decision guidance for the estimation of soil organic carbon (SOC) in support of appropriate deployment of sustainable land management (SLM) technologies, in order to maintain or increase carbon in the soil and contribute to the achievement of land degradation neutrality (LDN).

Land Degradation Neutrality for Biodiversity Conservation

Global

Land degradation and biodiversity loss are among the most pressing environmental challenges facing humanity. Land degradation has reduced the productivity of nearly one-quarter of the global land surface, impacted the wellbeing of about 3.2 billion people and cost about 10% of annual global gross domestic product in lost ecosystem services. An estimated 23% of total anthropogenic greenhouse gas emissions derive from agriculture, forestry and other land uses, contributing to climate change.

Land in numbers: Livelihoods at a tipping point

Journal Articles & Books
Novembro, 2014
Global

Numbers can tell a compelling story. In this brochure, the numbers highlight how much we rely on productive land. Amongst other valuable services, land feeds our families, provides fresh water and powers our future ambitions. Much of the data collected here, however, demonstrate how close we are to pushing our relationship with the land to breaking point. The magnitude of the challenges and potential consequences of failing to implement bold action on land and soil, in terms of future social stability and economic development, should not be underestimated.

Located in the arid and semi-arid areas of West Africa, the Sahel has undergone profound changes over the past 50 years. Known for the prevalence of land degradation processes, the Sahel is suffering from the combined negative effects of population growth, human activities and climate variability, resulting in recurrent droughts and the continued decline of natural resources and land productivity.
