Protected area downgrading, downsizing, and degazettement (PADDD) events are processes that change the legal status of national parks and other protected areas in both terrestrial and marine environments. [1] [2] "Downgrading" is "a decrease in legal restrictions on the number, magnitude, or extent of human activities within a protected area (i.e., legal authorization for increased human use)." [1] "Downsizing" refers to a "decrease in size of a protected area as a result of excision of land or sea area through a legal boundary change." [1] "Degazettement" is defined as a loss of legal protection for an entire national park or other protected area. [1] Collectively, PADDD represents legal processes that temper regulations, shrink boundaries, or eliminate legal protections originally associated with establishment of a protected area.
PADDD is a phenomenon that has recently gained attention among scientists and policymakers. [1] [3] [4] [5] Scientific publications have identified 3,749 enacted PADDD events in 73 countries since 1892. [5] Collectively, PADDD events have removed protections from at least 519,857 km2 and reduced restrictions in an additional 1,659,972 km2. [5]
While proximate causes of PADDD vary widely, most PADDD events globally (62%) are related to agriculture, mining, oil and gas, forestry, fisheries, and industrialization. [5] Only 1.7% of PADDD events globally are associated with conservation planning. [5]
PADDD is a historical and contemporary phenomenon. [1] 78% of PADDD events worldwide were enacted since 2000 and 64% were enacted between 2008 and 2018. [5] Governments in at least 24 countries have proposed 847 PADDD events; governments in at least 14 countries are currently considering at least 46 PADDD proposals. [5]
PADDD has been studied and documented globally. Research on PADDD in Africa, Asia, and Latin America, which together contain most global conservation priorities and over 70% of all protected lands and waters, suggests significant tradeoffs between conservation and other policy objectives. [3] In the absence of PADDD, four countries in Africa would have met 2020 targets for protected area coverage established under the Convention on Biological Diversity. [3] In Brazil, PADDD events eliminated 6% of the total potential terrestrial protected area estate. [6] These PADDD events were primarily associated with hydropower and rural human settlements. [6] Research on PADDD in Australia has identified over 1,500 PADDD events, mostly associated with downgrading protections. Collectively, these PADDD events impacted over one-third of Australia’s protected area network. [7]
PADDD challenges longstanding assumptions that underlie established conservation strategies. For example, the assumption that protected areas are permanent fixtures on the landscape is foundational to Reducing Emissions from Deforestation and Forest Degradation (REDD+) policies. [1] Research on PADDD in three REDD+ priority countries (Malaysia, Peru, and Democratic Republic of the Congo) identified that rates of forest carbon emissions and deforestation were substantially higher in PADDDed forests relative to protected areas and slightly higher in PADDDed forests relative to never-protected areas. [8] Furthermore, iconic protected areas are not immune to PADDD. UNESCO World Heritage Sites, including Yasuníi National Park (Ecuador) and Virunga National Park (DRC), have been subject to 23 enacted and proposed PADDD events. [9] A case study of Yosemite National Park revealed that PADDD reduced the size of the park by 30% and lands that were removed from protection (downsized) were more fragmented than protected lands. [10]
Protected areas are among the most effective conservation measures, critical to global efforts to safeguard species and mitigate the impacts of climate change. [11] [12] [13] Rolling back protections for industrial-scale extraction may compromise biodiversity conservation efforts and ecosystem services afforded by protected areas. [5] [6]
PADDD suggests that conservation success is dependent not only on the creation of new protected areas but also the maintenance of existing protected areas. [9] Scientists highlight the need for decision-makers to consider protected area characteristics and the socioeconomic context in which they are situated to better ensure their permanence. [14] Research has indicated that less effective protected areas, in which deforestation rates were similar to unprotected sites nearby, were more likely to be degazetted. [15] These findings suggest that bolstering the ecological benefits of protected areas may improve their durability. [15] Scientists have suggested that the global PADDD trend could be combatted via a systematic programme of protected area "upgrading," whereby conserved wild areas are expanded via the purchase or gazetting of surrounding territory. [16] Successful examples of protected-area upgrading include Gorongosa National Park in Mozambique and the Guanacaste Conservation Area in Costa Rica. [16]
PADDD was a topic of discussion at the World Parks Congress in Sydney, Australia, in November, 2014. [17] PADDD was included in Motion 026 of the IUCN World Conservation Congress in Honolulu, Hawaii in 2016: “The World Conservation Congress, at its session in Hawai‘i, United States of America, 1–10 September 2016...Calls on governments not to de-gazette, downgrade or alter the boundaries of all categories of protected areas to facilitate environmentally damaging industrial activities and infrastructure development." [18]
IUCN 2020 World Conservation Congress Resolution 084 calls for a Global Response to PADDD, calling on IUCN members to strengthen protected areas; acknowledge the risks associated with unrestrained and poorly-governed PADDD for biodiversity conservation; refrain from enacting or investing in PADDD events that will lead to further extensive development. [19]
Ongoing responses to PADDD include Project Finance for Permanence (PFP), which is an innovative method to secure permanent funding for conservation areas. [20] The largest PFP, Amazon Region Protected Areas (ARPA), permanently financed conservation initiatives in 15 percent of the Brazilian Amazon. [21] [22]
The Legacy Landscapes Fund is an initiative to support protected areas for the long-term. It aims to support 30 protected areas by 2030 with sustainable funding totaling $1B USD. [23]
Ongoing debates surrounding PADDD events around the world appear regularly in the media; see PADDDtracker Twitter and Parkwire for examples.
Several additional studies have highlighted PADDD around the world including: China (Ma et al, Huang et al), Bhutan (Dorji et al), South Africa (De Vos et al), Mexico (Lebreton, Depraz et al), the Caucasus region (Mancheno et al), Ecuador (López Sandoval et al) and Brazil (Laue & Arima, Bernard et al, Correia et al, Villen et al).

Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural processes that sustain life.
Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of the U.N.'s Convention on Biodiversity. Ultimately, these movements should be further promoted to encourage biodiversity and to conserve a functional ecosystem.
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources is limited.
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable".
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management.
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
Wilderness or wildlands are natural environments on Earth that have not been significantly modified by human activity, or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one-quarter of Earth's terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity.
Habitat destruction occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide.
Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution, climate change, and the illegal wildlife trade. The IUCN estimates that 42,100 species of the ones assessed are at risk for extinction. Expanding to all existing species, a 2019 UN report on biodiversity put this estimate even higher at a million species. It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife. Prominent conservation agreements include the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the 1992 Convention on Biological Diversity (CBD). There are also numerous nongovernmental organizations (NGO's) dedicated to conservation such as the Nature Conservancy, World Wildlife Fund, the Wild Animal Health Fund and Conservation International.
Marine protected areas (MPA) are protected areas of the world's seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations, MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish. The value of MPA to mobile species is unknown.
In biology, a refugium is a location which supports an isolated or relict population of a once more widespread species. This isolation (allopatry) can be due to climatic changes, geography, or human activities such as deforestation and overhunting.
Environmental issues in Bolivia include deforestation caused by commercial agriculture, urbanization, and illegal logging, and biodiversity loss attributed to illegal wildlife trade, climate change, deforestation, and habitat destruction. Since 1990, Bolivia has experienced rapid urbanization raising concerns about air quality and water pollution.
MARXAN is a family of software designed to aid systematic reserve design on conservation planning. With the use of stochastic optimisation routines Marxan generates spatial reserve systems that achieve particular biodiversity representation goals with reasonable optimality. Over the years, Marxan has grown from its standard two zone application to consider more complex challenges like incorporating connectivity, probabilities and multiple zones. Along the way, Marxan’s user community has also built plug-ins and interfaces to assist with planning projects.
The national parks of Madagascar include all officially recognized protected areas as of 2015. The protected areas network of Madagascar is managed by the Madagascar National Parks Association (PNM-ANGAP). The network includes three types of protected areas: Strict Nature Reserves, National Parks and Wildlife Reserves. At the 2003 IUCN World Parks Congress in Durban, the Malagasy President, Marc Ravalomanana, announced an initiative to more than triple the area under protection from approximately 4,200,791 acres (17,000.00 km2) to over 14,826,322 acres (60,000.00 km2). This "Durban Vision", as it has been dubbed, involved broadening the definition of protected areas in the country and legislation has been passed to allow the creation of four new categories of protected area: Natural Parks, Natural Monuments, Protected Landscapes, and Natural Resource Reserves. As well as allowing these new objectives for protected areas management, the new legislation also provided for entities other than PNM-ANGAP to manage protected areas, such as government ministries, community associations, NGOs and other civil society organizations, and the private sector.
Wildlife trade refers to the products that are derived from non-domesticated animals or plants usually extracted from their natural environment or raised under controlled conditions. It can involve the trade of living or dead individuals, tissues such as skins, bones or meat, or other products. Legal wildlife trade is regulated by the United Nations' Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which currently has 184 member countries called Parties. Illegal wildlife trade is widespread and constitutes one of the major illegal economic activities, comparable to the traffic of drugs and weapons.
Landscape-scale conservation is a holistic approach to landscape management, aiming to reconcile the competing objectives of nature conservation and economic activities across a given landscape. Landscape-scale conservation may sometimes be attempted because of climate change. It can be seen as an alternative to site based conservation.
Defaunation is the global, local, or functional extinction of animal populations or species from ecological communities. The growth of the human population, combined with advances in harvesting technologies, has led to more intense and efficient exploitation of the environment. This has resulted in the depletion of large vertebrates from ecological communities, creating what has been termed "empty forest". Defaunation differs from extinction; it includes both the disappearance of species and declines in abundance. Defaunation effects were first implied at the Symposium of Plant-Animal Interactions at the University of Campinas, Brazil in 1988 in the context of Neotropical forests. Since then, the term has gained broader usage in conservation biology as a global phenomenon.
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.
Biodiversity loss happens when various species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. This in turn leads to a reduction in biological diversity in that area. The decrease can be temporary or permanent. It is temporary if the damage that has led to the loss is reversible in time, for example through ecological restoration. If this is not possible then the decrease is permanent. This ongoing global extinction is a biodiversity crisis. The cause for most of the biodiversity loss are those human activities that push the planetary boundaries too far.
Keo Seima Wildlife Sanctuary is a 2,926.9 km2 (1,130.1 sq mi) protected area of mixed seasonal tropical forest in eastern Cambodia, located in Mondulkiri and Kratié provinces. The area was first established as Seima Biodiversity Conservation Area in 2002, later becoming Seima Protection Forest in 2009, finally becoming Keo Seima Wildlife Sanctuary in 2016. The site is of national, regional, and global importance for a range of biodiversity, with more than 950 species recorded within the protected area. It is also the ancestral and contemporary home of a large number of the Bunong ethnic group.
