The United Nations Decade on Ecosystem Restoration runs from 2021 to 2030. Similar to other nature related international decades, its purpose is to promote the United Nation's environmental goals. Specifically, to facilitate global cooperation for the restoration of degraded and destroyed ecosystems. Along with fostering efforts to combat climate change, safeguard biodiversity, food security, and water supply. While much focus is on promoting restoration activity by national governments, the UN also wishes to promote such efforts from other actors, ranging from the private sector and NGOs to regular individuals.
Following on from the 2011 - 2020 United Nations Decade on Biodiversity, the decade on Ecosystem Restoration was launched in June 2021. The United Nations called for countries to follow through on existing pledges to restore a total area similar to the size of China by 2030. They also say the overarching goal of the decade is to catalyse a nature friendly movement that lasts beyond the 10 year timeframe.
The United Nations decade on Ecosystem Restoration began on World Environment Day, 5 June 2021. In a June 2021 report to help launch the decade, the UN called for nations to deliver on existing ecosystem restoration commitments, which in total add up to over 1 billion hectares, an area bigger than China. About half the world's GDP is directly dependent on nature, yet mankind is depleting natural resources at about 1.6x the rate at which nature can restore them. Already about 40% of the world's population suffers due to ecosystem depletion, with close to 20% of countries at risk of ecosystem collapse. The report advised that restoration efforts to address this could contribute about a third of the climate change mitigation needed by 2030, as well as protect nature and biodiversity, with significant benefits to humans in terms of physical health, mental health and economically. [1] [2] [3]
The UN also call for additional efforts beyond the existing pledges, including for action to restore aquatic ecosystems, and for a lasting global movement to endure after 2030. The UN also stated that while efforts from national governments are vital, everyone has a role to play, including the private sector, NGOs and individuals. [1] [2]
The UN define ecosystem restoration as "the process of halting and reversing degradation, resulting in improved ecosystem services and recovered biodiversity". [1] In practice, a particular restoration can involve quite different transitions, depending on what best suits the local conditions.
The UN advise that different approaches to ecosystem restoration are needed - what works well in one area might fail in another. Approaches they recommend include regenerative agriculture, ecological restoration and rewilding. [1]
The UN Decade on Ecosystem Restoration is co-led by two UN agencies - the UNEP and the Food and Agriculture Organization (FAO). [4] Other key bodies involved are the Center for International Forestry Research (CIFOR), the International Union for Conservation of Nature (IUCN), and the Global Landscapes Forum (GLF). In supporting the UN Decade, they will partner with other UN agencies, bodies and convention secretariats, and with international and indigenous organisations. [5] [2]
During the Bonn Challenge 3.0 high-level meeting in March 2018, El Salvador announced plans to propose a United Nations Decade on Ecosystem Restoration 2021–2030, aimed at boosting existing efforts to restore degraded ecosystems. [6] El Salvador's leadership on ecosystem restoration arose out of its support for the Bonn Challenge, which aims to restore 350 million hectares of degraded ecosystems globally by 2030, and endorsement of the New York Declaration on Forests. [7] [8] As one of the six Bonn Challenge pilot countries, El Salvador has pledged to restore 1 million hectares, equivalent to half of the country's territory. [9]
71 countries supported the proposal at its presentation by El Salvador's Minister of Environment and Natural Resources, Lina Pohl, to the 73rd session of the United Nations General Assembly in September 2018. [10] On 1 March 2019, the UN General Assembly officially adopted the resolution declaring 2021–2030 the UN Decade of Ecosystem Restoration. [11]
According to Minister Pohl, "Ecosystem restoration promoted through this UN Decade takes a multi-functional landscape approach, looking at the mosaic of interdependent land uses in which ecological, economic, social, and development-based priorities can find convergence, balance, and complementarity." [6] [10]
Pre launch material suggested the United Nations Decade on Ecosystem Restoration would focus on balancing ecological, social and developmental priorities in landscapes where different forms of land use interact, with the aim of fostering long term resilience. [6]
An ecosystem includes all living organisms, and their interaction with each other and their physical environment (such as soil, climate, atmosphere, and weather). [12] Each organism plays a key role and contributes to the health and productivity of the ecosystem as a whole. Ecosystems are interdependent, and damage or imbalance can have devastating and far-reaching consequences. [13] Biodiversity underlies all ecosystem services, which are the benefits that people obtain from ecosystems, indispensable to health, survival and wellbeing. [14] They include provisioning services (food, freshwater, wood and fibre, and fuel), [15] regulating services (modulating climate, disease, [16] food supply, and water purity), and cultural services (serving aesthetic, spiritual, and educational needs). [17]
Human activities are affecting the capacity of ecosystems to provide these goods and services. [18] [19] Drivers of biodiversity loss and decline in ecosystem functioning include climate change, deforestation, desertification and land degradation, freshwater decline, overexploitation, stratospheric ozone depletion, and pollution. Degradation of land and marine ecosystems adds to the threat of mass species extinction, and has a negative impact on the well-being of some 3.2 billion people, costing around 10% of the annual global gross domestic product (c. $6.3 trillion) in loss of species and ecosystem services. [20] Agricultural land and ecosystem degradation reduces resilience to climate change, which enhances the risk of catastrophic collapse in the face of rising temperatures and changes in rainfall patterns. [21] The benefits future generations can obtain from ecosystems will be greatly diminished unless these problems are addressed. [22]
Ecosystem restoration seeks to repair damage done by people to ecosystems and biodiversity. [23] It assists the recovery of degraded, damaged and destroyed ecosystems, to regain ecological functionality and provide goods and services of value to humans. [24] [25] The beneficial effects of ecosystem restoration include increased food and water security, contributing to climate change mitigation and adaptation, and managing the associated risks of conflict and migration. [21] The restoration of 350 million hectares of degraded terrestrial and aquatic ecosystems by 2030 could generate US$9 trillion in ecosystem services and remove 13 to 26 gigatons of greenhouse gases from the atmosphere. [26] The benefits obtained from ecosystem generation on average exceed the costs of the initial investment tenfold, whereas the cost of inaction is at least three times the cost of ecosystem restoration. [21]
Around 2 billion hectares of degraded lands worldwide have potential for ecosystem restoration. [27] Most of the rehabilitation work could take the form of "mosaic restoration", in which forests are combined with protected areas, agriculture, waterbodies, and human settlements on a landscape-wide scale. [28]
Transformational ecosystem restoration requires strong commitment, and the efforts of countries, the international community, civil society, the private sector, and other actors. Achieving the Bonn Challenge objective of restoring at least 350 million hectares of degraded landscapes by 2030 [6] could realize up to $9 trillion in net benefits, and alleviate poverty in many rural communities. [11] The UN Decade aims to promote a concerted and holistic landscape-focused approach to the interdependence of ecosystems, human needs, and biodiversity, to accelerate the progress needed to maintain and restore ecosystems. [6]
The UN Decade on Ecosystem Restoration was established in order to: [6]
Ecosystem restoration is recognized as a key component in achieving targets under existing international conventions and agreements. These include the 2030 Agenda for Sustainable Development and, under it, the Sustainable Development Goals (SDGs), [29] the Strategic Plan for Biodiversity 2020 and its Aichi Biodiversity Targets, [30] the United Nations Framework Convention on Climate Change and Paris Agreement, the United Nations Convention to Combat Desertification and its target of Land Degradation Neutrality, [31] the Ramsar Convention, and the United Nations Strategic Plan on Forests 2017 – 2030. [32]
Ecosystem restoration will contribute to all 17 Sustainable Development Goals, in particular to SDG15 (Life on Land), SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation), SDG 7 (Affordable and Clean Energy), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), SDG 14 (Life Below Water) and SDG 17 (Partnerships for the Goals). [29] Paragraph 27 of the Ministerial Declaration of the High-Level Political Forum on the SDGs held in July 2018 sets out commitments made to achieve sustainable management of all types of forests, halt deforestation, restore degraded forests, and substantially increase afforestation and reforestation globally by 2020. [33]
Planned activities during the UN Decade on Ecosystem Restoration are also designed to contribute to the Bonn Challenge to restore degraded and deforested land. The UN Decade builds on regional restoration efforts, such as Initiative 20x20 in Latin America, which aims to restore 20 million hectares of degraded land by 2030; [34] and the AFR100 African Forest Landscape Restoration Initiative, [35] that aims to bring 100 million hectares of degraded land under restoration by 2030.
Resolutions relevant to ecosystem restoration adopted during past UN Environment Assemblies (UNEA) of the United Nations Environment Program (UNEP) include:
The following resolutions adopted during the fourth UNEA, from 11 to 15 March 2019, highlight the importance of ecosystem restoration: [39]
Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest, and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife.
Sustainable development is an organizing principle that aims to meet human development goals while also enabling natural systems to provide necessary natural resources and ecosystem services to humans. The desired result is a society where living conditions and resources meet human needs without undermining the planetary integrity and stability of the natural system. Sustainable development tries to find a balance between economic development, environmental protection, and social well-being. The Brundtland Report in 1987 defined sustainable development as "development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs". The concept of sustainable development nowadays has a focus on economic development, social development and environmental protection for future generations.
The United Nations Environment Programme (UNEP) is responsible for coordinating responses to environmental issues within the United Nations system. It was established by Maurice Strong, its first director, after the United Nations Conference on the Human Environment in Stockholm in June 1972. Its mandate is to provide leadership, deliver science and develop solutions on a wide range of issues, including climate change, the management of marine and terrestrial ecosystems, and green economic development. The organization also develops international environmental agreements; publishes and promotes environmental science and helps national governments achieve environmental targets.
Natural capital is the world's stock of natural resources, which includes geology, soils, air, water and all living organisms. Some natural capital assets provide people with free goods and services, often called ecosystem services. All of these underpin our economy and society, and thus make human life possible.
Rio Convention relates to the following three conventions, which were agreed at the Earth Summit held in Rio de Janeiro in June 1992.
The Trillion Tree Campaign is a project which aims to plant one trillion trees worldwide. It seeks to repopulate the world's trees and combat climate change as a nature-based solution. The project was launched at PlantAhead 2018 in Monaco by Plant-for-the-Planet. In the fall of 2018, the project's official website was published in order to register, monitor, and donate trees to reforestation projects around the world. The campaign is a continuation of the activities of the earlier Billion Tree Campaign, instigated by Wangari Maathai, who founded the Green Belt Movement in Africa in 1977.
Sustainability is a social goal for people to co-exist on Earth over a long time. Specific definitions of this term are disputed and have varied with literature, context, and time. Experts often describe sustainability as having three dimensions : environmental, economic, and social, and many publications emphasize the environmental dimension. In everyday use, sustainability often focuses on countering major environmental problems, including climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. The idea of sustainability can guide decisions at the global, national, and individual levels. A related concept is sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "Sustainability is often thought of as a long-term goal, while sustainable development refers to the many processes and pathways to achieve it."
The World Day to Combat Desertification and Drought is a United Nations observance celebrated each year on 17 June. Its purpose is to raise awareness of the presence of desertification and drought, highlighting methods of preventing desertification and recovering from drought. Each year's global celebration has a unique, novel emphasis that had not been developed previously.
Trees for the Future is a Maryland-based nonprofit organization founded on August 14, 1989, that trains farmers around the world in agroforestry and sustainable land use.
The International Resource Panel is a scientific panel of experts that aims to help nations use natural resources sustainably without compromising economic growth and human needs. It provides independent scientific assessments and expert advice on a variety of areas, including:
Forest restoration is defined as “actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest” i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans. Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Additionally, the potential impacts of climate change on restoration goals must be taken into account, as changes in temperature and precipitation patterns may alter the composition and distribution of climax forests.
The Sustainable Development Goals (SDGs) or Global Goals are a collection of seventeen interlinked objectives designed to serve as a "shared blueprint for peace and prosperity for people and the planet, now and into the future." The short titles of the 17 SDGs are: No poverty, Zero hunger, Good health and well-being, Quality education, Gender equality, Clean water and sanitation, Affordable and clean energy, Decent work and economic growth, Industry, innovation and infrastructure, Reduced inequalities, Sustainable cities and communities, Responsible consumption and production, Climate action, Life below water, Life on land, Peace, justice, and strong institutions, and Partnerships for the goals.
Deforestation is a primary contributor to climate change, and climate change affects forests. Land use changes, especially in the form of deforestation, are the second largest anthropogenic source of atmospheric carbon dioxide emissions, after fossil fuel combustion. Greenhouse gases are emitted during combustion of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions. As of 2019, deforestation is responsible for about 11% of global greenhouse gas emissions. Carbon emissions from tropical deforestation are accelerating. Growing forests are a carbon sink with additional potential to mitigate the effects of climate change. Some of the effects of climate change, such as more wildfires, insect outbreaks, invasive species, and storms are factors that increase deforestation.
The Global Peatlands Initiative is an effort made by leading experts and institutions formed in 2016 by 13 founding members at the UNFCCC COP in Marrakech, Morocco. The mission of the Initiative is to protect and conserve peatlands as the world's largest terrestrial organic carbon stock and to prevent it from being emitted into the atmosphere.
Sustainable Development Goal 15 is about "Life on land". One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". The Goal has 12 targets to be achieved by 2030. Progress towards targets will be measured by 14 indicators.
Sustainable Development Goal 14 is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording is to "Conserve and sustainably use the oceans, seas and marine resources for sustainable development". The Goal has ten targets to be achieved by 2030. Progress towards each target is being measured with one indicator each.
Sustainable Development Goal 12, titled "responsible consumption and production", is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording of SDG 12 is "Ensure sustainable consumption and production patterns". SDG 12 is meant to ensure good use of resources, improve energy efficiency and sustainable infrastructure, provide access to basic services, create green and decent jobs, and ensure a better quality of life for all. SDG 12 has 11 targets to be achieved by at least 2030, and progress towards the targets is measured using 13 indicators.
Sustainable Development Goal 2 aims to achieve "zero hunger". It is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording is: "End hunger, achieve food security and improved nutrition and promote sustainable agriculture". SDG 2 highlights the "complex inter-linkages between food security, nutrition, rural transformation and sustainable agriculture". According to the United Nations, there are around 690 million people who are hungry, which accounts for slightly less than 10 percent of the world population. One in every nine people goes to bed hungry each night, including 20 million people currently at risk of famine in South Sudan, Somalia, Yemen and Nigeria.
The Kunming-Montreal Global Biodiversity Framework (GBF) is an outcome of the 2022 United Nations Biodiversity Conference. Its tentative title had been the "Post-2020 Global Biodiversity Framework". The GBF was adopted by the 15th Conference of Parties (COP15) to the Convention on Biological Diversity (CBD) on 19 December 2022. It has been promoted as a "Paris Agreement for Nature". It is one of a handful of agreements under the auspices of the CBD, and it is the most significant to date. It has been hailed as a "huge, historic moment" and a "major win for our planet and for all of humanity."
Peatland restoration is a term describing measures to restore the original form and function of peatlands, or wet peat-rich areas. This landscape globally occupies 400 million hectares or 3% of land surface on Earth. Historically, peatlands have been drained for several main reasons; peat extraction, creation of agricultural land, and forestry usage. However, this activity has caused degradation affecting this landscape's structure through damage to habitats, hydrology, nutrients cycle, carbon balance and more.
