Billions of people around the world are suffering the consequences of the climate emergency, food and water insecurity, and the COVID-19 pandemic. Ecosystems are an indispensable ally as we meet these challenges. Protecting them and managing their resources in a sustainable manner is essential. But just increasing the protection and sustainable management of our remaining natural landscapes and oceans will not be enough: the planet’s degraded ecosystems and the huge benefits that they provide must also be restored. By declaring the UN Decade on Ecosystem Restoration, governments have recognized the need to prevent, halt and reverse the degradation of ecosystems worldwide for the benefit of both people and nature. The 2021–2030 timeline underlines the urgency of the task. Without a powerful 10-year drive for restoration, we can neither achieve the climate targets of the Paris Agreement, nor the Sustainable Development Goals. This report presents the case for why we all must throw our weight behind a global restoration effort. Drawing on the latest scientific evidence, it explains the crucial role played by ecosystems from forests and farmland to rivers and oceans, and charts the losses that result from our poor stewardship of the planet. The UN Decade on Ecosystem Restoration provides a unique opportunity to transform food, fibre and feed production systems to meet the needs of the 21st century, and to eradicate poverty, hunger and malnutrition. This we seek to achieve through effective and innovative landscapes and seascapes management that prevents and halts degradation, and restores degraded ecosystems. The restoration of forest landscapes, farming, livestock and fish-producing ecosystems should primarily contribute to restoring them to a healthy and stable state, so that they are able to provide ecosystems services and support human needs for sustainable production and livelihoods. For example, around one third of the world’s farmland is degraded, about 87 per cent of inland wetlands worldwide have disappeared since 1700, and one third of commercial fish species are overexploited. Degradation is already affecting the well-being of an estimated 3.2 billion people – that is 40 per cent of the world’s population. Every single year, we lose ecosystem services worth more than 10 per cent of our global economic output. If we can manage to reverse this trend, massive gains await us. Reviving ecosystems and other natural solutions could contribute over one third of the total climate mitigation needed by 2030. Restoration can also curb the risk of mass species extinctions and future pandemics. Agroforestry alone could increase food security for 1.3 billion people. Restoration on a global scale requires sustained investments. But there is growing evidence that it more than pays for itself. For example, restoring coral reefs to good health by 2030 could yield an extra USD 2.5 billion a year for both Mesoamerica and Indonesia; having doubled its forest cover since the 1980s, Costa Rica has seen ecotourism grow to account for 6 per cent of GDP. While restoration science is a youthful discipline, we already have the knowledge and tools we need to halt degradation and restore ecosystems. Farmers, for instance, can draw on proven restorative practices such as sustainable farming and agroforestry. Landscape approaches that give all stakeholders – including women and minorities – a say in decision-making are simultaneously supporting social and economic development and ecosystem health. And policy makers and financial institutions are realizing the huge need and potential for green investment. The United Nations stands behind this crucial initiative. As well as contributing research to this report, the United Nations Environment Programme (UNEP) and Food and Agriculture Organization (FAO) along with their partners will provide leadership, coordination and technical support throughout the UN Decade. International cooperation can help countries to implement their existing restoration pledges, which cover more than 1 billion hectares, an area bigger than China. Global meetings on climate and biodiversity slated for later this year are an opportunity for governments to increase their ambition further, and to force the pace of implementation. But long-term success will depend on the UN Decade realizing its overarching goal of catalysing a global movement that outgrows and outlives the 10-year timeframe. By engaging in restoration, everyone – from governments and businesses to civil society groups and individuals – can contribute towards resetting our relationship with nature.

GONZALES, KAYRI HAVENS, MARION KARMANN, FRANCIS F. KILKENNY, SIEGFRIED L. KRAUSS, ANDREW J. LOWE, PEDRO MARQUES, PAUL G. NEVILL, PATI L. VITT, AND ANNA BUCHAROVA Selecting the geographic origin—the provenance—of seed is a key decision in restoration. The last decade has seen a vigorous debate on whether to use local or nonlocal seed. The use of local seed has been the preferred approach because it is expected to maintain local adaptation and avoid deleterious population effects (e.g., maladaptation and outbreeding depression). However, the impacts of habitat fragmentation and climate change on plant populations have driven the debate on whether the local-is-best standard needs changing. This debate has largely been theoretical in nature, which hampers provenance decision-making. Here, we detail cross-sector priority actions to improve provenance decision-making, including embedding provenance trials into restoration projects; developing dynamic, evidence-based provenance policies; and establishing stronger research–practitioner collaborations to facilitate the adoption of research outcomes. We discuss how to tackle these priority actions in order to help satisfy the restoration sector’s requirement for appropriately provenanced seed.

  • First International Forum for the Rights of Mother Earth
    First International Forum for the Rights of Mother Earth Celebrating World Environment Day Mexico City | June 1-5 2016 First International Forum for the Rights of Mother Earth 2 Movement: horizon, path, and destiny Horizon It is time to globalize legislation for the Rights of Mother Earth and establish a Universal Declaration of the Rights of Nature, to recog- nize her as a living being- the biggest of all-, to protect her, restore her, and link her to humanity by way of respect and preservation of all her species. Only this action can stop the irrational exploitation and the utilita- rian view that today drives the relationship between mankind and Nature. Therefore, this declaration is the first step to ensure the future of the innumerable forms of existence, including the human species, on our planet. Path Mexico has gained significant legal steps to shift from an anthro- pocentric to a biocentric view, such as the Law of Protection of the Earth in Mexico City and the constitutional recognition of the rights of Nature in the state of Guerrero. These legislative advancements First International Forum for the Rights of Mother Earth 3 motivate various national and international organizations and so- cial networks to convene the First International Forum for the Ri- ghts of Mother Earth on June 1st through 5th, 2016 in Mexico City, surrounding World Environment Day, celebrated on June 5th. Destiny The First International Forum for the Rights of Mother Earth brings legislators, scientists, philosophers, ecologists, artists, keepers of ancient traditions, and social and spiritual leaders together to de- fine actions that ignite social awareness —extensive, diverse, and in solidarity— centered around the importance of legislating the Rights of Mother Earth.

Framing the Discussion 2. The Impetus for Change 3. Defining Sustainable Agriculture 4. Benefits of Sustainable Agriculture 5. What A Sustainable Agriculture System Will Look Like Framing the Discussion: Sustainable Agriculture = Sustainable Society Developing a sustainable agriculture is a necessary part of creating a sustainable society. The root of the word sustainable is the verb, to sustain, which means to nourish and prolong. In social and environmental contexts we say something is sustainable when we believe it can persist indefinitely without exhausting resources or causing lasting damage. The actions we take as individuals are at the core of both the problems and the solutions. Just by purchasing conventional goods at your local supermarket, you cause 4 lbs of pesticides to be put into the environment each year. The food supply chain averages of 4200 miles to reach your plate, when it could come from local farms and use a fraction of the transportation fuels. And the 2.6 acres of U.S. farmland (your pro-rata share) have lost 50% of the carbon in the soil since 1907, the equivalent CO2 of burning 90 barrels of oil – on top of your normal carbon emissions. Cumulatively, agriculture impacts our society at a scope and scale that few appreciate, far beyond the initial realms of our food safety, quality, and the local environment. Due to the scale of natural resources required to provide food, fiber and fuel to 6.7 billion people, agriculture requires continued global-scale supplies of fertile land, clean water, fossil fuels, fertilizers, pesticides, and transportation infrastructure.

  • The Time to Act Is
    The Time to Act is Now Grassroots Multi-Faith Action for the Earth Introduction Religious communities are at a crossroads with our response to climate change and other imminent threats to the environment. For much of the past 15 years, religious communities’ primary focus has been education and awareness raising on climate change, teaching that our faiths and their central teachings apply not only between people and to the Sacred, but person to planet. That education, while still vital, is not enough. We must take bold public action. We’ve seen the magnitude of the crisis. We know that public action at scale is absolutely essential. On 11 March, 2021, diverse religious and spiritual communities in 49 countries carried out 420 actions to draw attention to the climate crisis. The Sacred People, Sacred Earth day of action was organized by a grassroots, global, multi-faith alliance called the GreenFaith International Network. You can experience the energy and passion of these actions by watching this short video on Sacred People, Sacred Earth. Around Earth Day in April and World Environment Day in June, religious and spiritual leaders around the world often offer a sermon, khutbah, dharma teaching, dvar torah, or other spoken message on the climate crisis. The religious or spiritual gatherings around these days, and every gathering of its kind, offers an opportunity to convey how our different faiths compel us to take bold action on climate change. The actions organized by grassroots people of diverse faiths worldwide, a few of which are featured in this document, offer powerful instructional examples of religious belief in action, examples which can help pastors, imams, gurus, priests, rabbis, and other spiritual leaders bring to life the importance of public, morally-rooted action on climate change.

  • Fact Sheet on Health and Biodiversity
    Living in harmony with nature Health and Biodiversity We rely on biodiversity to stay healthy. Biodiversity sustains our food supply, is a source of medicines, and supports the provision of clean air and fresh water while also contributing to economic development, cultural and spiritual enrichment. It is now also widely recognized that biodiversity is affected by climate change, with negative consequences for human well-being, but biodiversity, through the ecosystem services it supports, also makes an important contribution to both climate change mitigation and adaptation. As all people require freedom from illness as well as social, emotional, physical, spiritual and cultural well-being, we cannot have healthy societies without biodiversity. Changes to biodiversity can have severe and unpredictable effects on the health of all living things, including people. Clearing new land, for example, can bring people into closer contact with wildlife that may transmit their diseases to humans and also promote the spread of disease from humans to animals. It may also reduce populations of predators that hold disease-carrying organisms in check. In addition, clearing of land may bring about the loss of plants and other organisms useful in medical research or that may contain substances used as medicines. People in developing countries face particularly heavy health burdens from a loss of biodiversity, with impacts on food supply and quality, medicines, and cultural and religious values. It has been estimated that approximately 80% of the world’s population from developing countries rely mainly on traditional medicines derived from plants and that 25% of prescriptions dispensed in United States pharmacies contained plant extracts or active ingredients derived from plants.

  • Evolutionary Restoration Ecology
    ch06 2/9/06 12:45 PM Page 113 189686 / Island Press / Falk Chapter 6 Evolutionary Restoration Ecology Craig A. Stockwell, Michael T. Kinnison, and Andrew P. Hendry Restoration Ecology and Evolutionary Process Restoration activities have increased dramatically in recent years, creating evolutionary chal- lenges and opportunities. Though restoration has favored a strong focus on the role of habi- tat, concerns surrounding the evolutionary ecology of populations are increasing. In this con- text, previous researchers have considered the importance of preserving extant diversity and maintaining future evolutionary potential (Montalvo et al. 1997; Lesica and Allendorf 1999), but they have usually ignored the prospect of ongoing evolution in real time. However, such contemporary evolution (changes occurring over one to a few hundred generations) appears to be relatively common in nature (Stockwell and Weeks 1999; Bone and Farres 2001; Kin- nison and Hendry 2001; Reznick and Ghalambor 2001; Ashley et al. 2003; Stockwell et al. 2003). Moreover, it is often associated with situations that may prevail in restoration projects, namely the presence of introduced populations and other anthropogenic disturbances (Stockwell and Weeks 1999; Bone and Farres 2001; Reznick and Ghalambor 2001) (Table 6.1). Any restoration program may thus entail consideration of evolution in the past, present, and future. Restoration efforts often involve dramatic and rapid shifts in habitat that may even lead to different ecological states (such as altered fire regimes) (Suding et al. 2003). Genetic variants that evolved within historically different evolutionary contexts (the past) may thus be pitted against novel and mismatched current conditions (the present). The degree of this mismatch should then determine the pattern and strength of selection acting on trait variation in such populations (Box 6.1; Figure 6.1).

Sanders, Dean of Graduate Studies Date Abstract Habitat fragmentation is an important subject of research needed by park management planners, particularly for conservation management. The Castle Parks, in southwest Alberta, Canada, exhibit extensive habitat fragmentation from recreational and resource use activities. Umbrella and keystone species within The Castle Parks include grizzly bears, wolverines, cougars, and elk which are important animals used for conservation agendas to help protect the matrix of the ecosystem. This study identified and analyzed the nature of habitat fragmentation within The Castle Parks for these species, and has identified geographic areas of habitat fragmentation concern. This was accomplished using remote sensing, ArcGIS, and statistical analyses, to develop models of fragmentation for ecosystem cover type and Digital Elevation Models of slope, which acted as proxies for species habitat suitability.

Pacheco CQVR – Chemistry Research Centre, University of Trás-os-Montes and Alto Douro, Quinta de Prados Ap. 1013, Vila Real 5001-801, Portugal; [email protected] Received: 3 February 2020; Accepted: 4 February 2020; Published: 6 February 2020 Abstract: Sustainability is a utopia of societies, that could be achieved by a harmonious balance between socio-economic development and environmental protection, including the sustainable exploitation of natural resources. The present Special Issue addresses a multiplicity of realities that confirm a deviation from this utopia in the real world, as well as the concerns of researchers. These scholars point to measures that could help lead the damaged environment to a better status. The studies were focused on sustainable use of soils and water, as well as on land use or occupation changes that can negatively affect the quality of those resources. Some other studies attempt to assess (un)sustainability in specific regions through holistic approaches, like the land carrying capacity, the green gross domestic product or the eco-security models. Overall, the special issue provides a panoramic view of competing interests for land and the consequences for the environment derived therefrom. Keywords: water resources; soil; land use change; conflicts; environmental degradation; sustainability Competition for land is a worldwide problem affecting developed as well as developing countries, because the economic growth of activity sectors often requires the expansion of occupied land, sometimes to places that overlap different sectors. Besides the social tension and conflicts eventually caused by the competing interests for land, the environmental problems they can trigger and sustain cannot be overlooked.
