The extensive arable land and great biodiversity present in Latin America and the Caribbean (LAC) have the potential to ensure sustenance and a good quality of life for its more than 600 million inhabitants. LAC has experienced important changes in land use. When the Europeans arrived in the 15th century, the forest cover of LAC accounted for approximately 75 per cent of the territory.

Road to Restoration. A Guide to Identifying Priorities and Indicators for Monitoring Forest and Landscape Restoration

By declaring the Decade on Ecosystem Restoration, the UN has recognized that there are only 10 years left to restore the world's degraded land. Countries are striving to fight climate change by 2030 through their Paris Agreement commitments and the Sustainable Development Goals (SDGs). But in many cases, their climate and development agenda are disconnected, even though sustainability and development go hand in hand – especially for rural communities. The divide is particularly severe when it comes to restoring degraded land.

Forests, Trees and the Eradication of Poverty: Potential and Limitations

Global

The report, “Forests, Trees and the Eradication of Poverty: Potential and Limitations,” shows that forests and trees support human well-being and are critical to end poverty. It finds that forest-poverty dynamics are affected by a range of social, economic, political, and environmental context factors, such as rural outmigration, gender norms, remittance flows, and elite capture. The report’s key messages are highlighted below. Forests and trees can help the poor face global changes such as climate change. Benefits from forests and trees to human well-being are unevenly distributed.

Mapping Together: A Guide to Monitoring Forest and Landscape Restoration Using Collect Earth Mapathons

Mapping Together helps people use Collect Earth mapathons to monitor tree-based restoration. Collect Earth enables users to create precise data that can show where trees are growing outside the forest across farms, pasture, and urban areas and how the landscape has changed over time. Building on WRI and FAO’s Road to Restoration, a guide that helps people make tough choices and set realistic goals for restoring landscapes, Mapping Together takes this process one step further.

Bioenergy and sustainability: Bridging the gaps

Journal Articles & Books
Novembre, 2015
Global

The development of modern high efficiency bioenergy technologies has the potential to improve energy security and access while reducing environmental impacts and stimulating low-carbon development. While modern bioenergy production is increasing in the world, it still makes a small contribution to our energy matrix. At present, approximately 87% of energy demand is satisfied by energy produced through consumption of fossil fuels.

Projected land demands for bioenergy fall well within conservative estimates of current and future land availability (240 to 905 Mha). Estimates for the amount of modern bioenergy needed to meaningfully mitigate climate change range from 80 to 200 EJ in the 2050 timeframe. At the upper end of this range, we estimate that about 200 million hectares would be required. This may be compared to most estimates for the amount of land available for bioenergy, which exceed 500 million hectares.

Global Land Outlook: Northeast Asia Thematic Report: Partnerships to Achieve Land Degradation Neutrality

Deforestation, land degradation, and unsustainable land management threaten our lives and are responsible, both directly and indirectly, for many economic, social and environmental issues. In particular, countries in Northeast Asia face the growing threats of desertification, land degradation and drought (DLDD). In China, it is estimated that “more than 40 per cent of Chinese arable land is degraded” (China Daily 2014). “The annual cost of land degradation in Mongolia is estimated at 2.1 billion United States dollars (USD)” (UNCCD, 2018).

Land degradation and desertification reduce the provision of ecosystem services by lands and soils. This constrains development, reduces water, food, and energy security, and triggers resource conflicts. Although biophysical processes and economic impacts are increasingly understood, efforts to combat degradation have been failing thus far to prevent further losses of land productivity, a cost estimated at 42 billion USD/year (Dregne & Chou, 1992; Requier-Desjardins, 2007).

Land Degradation Neutrality is a new way of approaching land degradation that acknowledges that land and land-based ecosystems are affected by global environmental change as well as by local land use practices. Achieving the target of a land degradation neutral world encourages adaptive management during planning, implementation, and monitoring of LDN-related activities and follows the LDN response hierarchy of avoiding, reducing, and reversing land degradation.

Land Matters for Climate Reducing the Gap and Approaching the Target

Journal Articles & Books
Novembre, 2015
Global

The land use sector represents almost 25% of total global emissions. These emissions can be reduced. There is also great potential for carbon sequestration through the scaling up, and scaling out, of proven and effective practices. Improved land use and management, such as low-emissions agriculture, agro-forestry and ecosystem conservation and restoration could, under certain circumstances, further reduce the remaining emissions gap by up to 25%. These climate-smart land management practices nearly always come with adaptation co-benefits.

Land Degradation Neutrality: Interventions to Foster Gender Equality

Women constitute the bulk of people who rely on land in many of the regions most affected by desertification, land degradation and drought. One in three people on earth depend directly on agriculture, while nearly 80% of employed women in least developed countries report agriculture as their primary livelihood. Food availability fluctuations also impact women’s role in food production and intra-family food distribution, with women often reducing their nutritional intake and that of their children, with dire health consequences.

The UNEP foresight report contains a description of the 21 emerging environmental issues identified through the UNEP Foresight Process. The process resulted in a list of 21 emerging environmental issues tagged 21 Issues for the 21st Century covering the major themes of the global environment including food, land, freshwater, marine, biodiversity, climate change, energy, waste, and technology, as well important cross-cutting issues ranging from the need for better environmental governance, to the need for human behavioral change towards the environment.
