Integration of the Sustainable Development Goals and targets into the implementation of the United Nations Convention to Combat Desertification and the Intergovernmental Working Group report on land degradation neutrality
Indicator 15.3.1: Proportion of land that is degraded over total land area
Climate- and human-induced land degradation endangers the future survival of our planet. A new focus on achieving Land Degradation Neutrality (LDN) seeks to spark and grow transformative efforts to avoid, reduce and reverse land degradation through gender- and socially-equitable means.
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.
Land is the foundation for all life on Earth. How land is used and managed influences nature, food, water, energy, climate, and even our health. Today, the pressures on land and the wealth of resources it provides are greater than at any other time in human history.
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).
The Kyoto Protocol negotiated in the mid-1990s to address climate change adaptation and mitigation will be replaced by a post-Kyoto agreement in 2012. The new agreement under negotiation needs to seal the policy gaps in adaptation and mitigation that were omitted or excluded from Kyoto on account of scientific uncertainties. Particular attention needs to be given to the potential of land in all its dimensions considering its high capacity to store carbon. Land stores twice as much organic carbon as vegetation and the atmosphere combined.
Land has many uses. It provides water, food and energy. It is used to create wealth and employment and grow economies. And it provides other, often less obvious and tangible, services such as conserving biodiversity, storing carbon, purifying and storing water. It even regulates the Earth’s climate, for instance, by absorbing the heat from the sun. All of its uses are undermined and destroyed when land is degraded. Degrading the land disrupts these functions and leads to severe food, water and energy shortages.
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.
