Environmental conservation
- Biosphere reserves created under UNESCO's Man and Biosphere Programme with the objective of protecting larger landscapes and seascapes surrounding existing protected areas. These areas are considered sustainable use areas.
- World heritage sites are areas of universal natural and cultural value, declared under an international Convention for the Protection of the World Cultural and Natural Heritage. This status is usually given to an already designated protected area.
- Important bird areas are identified to give special attention to areas that are significant for bird conservation. These areas are identified by Birdlife International, an organisation based in the UK, with the help of national conservation organisations. These areas may or may not be covered under the country's protected area network.
- Wetlands of significant biodiversity value can be declared Ramsar sites. These sites are declared under an inter-governmental treaty on wetlands called the Ramsar Convention which was signed by countries at Ramsar, in Iran, in 1971. As of today, 160 countries have signed this convention which provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. This is the only inter-governmental treaty that deals with a specific ecosystem. Nineteen wetlands have been declared Ramsar sites in India, covering an area of almost 648,507 hectares.
- Conserve viable populations of prioritised native medicinal plant species in their natural habitat. Conduct studies on biological and ecological aspects of medicinal plants in order to develop appropriate conservation approaches.
- Sensitise and enable local communities and resource managers to manage MPCAs for effective conservation. Design and develop strategies and mechanisms for long-term conservation of medicinal plants.
- MPCAs are established in different bio-geographic zones and micro climates covering maximum habitat diversity and viable populations of prioritised medicinal plant species available in specific states. These are identified and managed in cooperation with state forest departments and local people.
- Strict Nature Reserve: Category Ia are strictly protected areas set aside to protect biodiversity and also possibly geological/geomorphical features, where human visitation, use and impacts are strictly controlled and limited to ensure protection of the conservation values. Such protected areas can serve as indispensable reference areas for scientific research and monitoring
- Wilderness Area: Category Ib protected areas are usually large unmodified or slightly modified areas, retaining their natural character and influence without permanent or significant human habitation, which are protected and managed so as to preserve their natural condition.
- National Park: Category II protected areas are large natural or near natural areas set aside to protect large-scale ecological processes, along with the complement of species and ecosystems characteristic of the area, which also provide a foundation for environmentally and culturally compatible, spiritual, scientific, educational, recreational, and visitor opportunities.
- Natural Monument or Feature: Category III protected areas are set aside to protect a specific natural monument, which can be a landform, sea mount, submarine cavern, geological feature such as a cave or even a living feature such as an ancient grove. They are generally quite small protected areas and often have high visitor value.
- Habitat/Species Management Area: Category IV protected areas aim to protect particular species or habitats and management reflects this priority. Many Category IV protected areas will need regular, active interventions to address the requirements of particular species or to maintain habitats, but this is not a requirement of the category.
- Protected Landscape/ Seascape: A protected area where the interaction of people and nature over time has produced an area of distinct character with significant, ecological, biological, cultural and scenic value: and where safeguarding the integrity of this interaction is vital to protecting and sustaining the area and its associated nature conservation and other values.
- Protected area with sustainable use of natural resources: Category VI protected areas conserve ecosystems and habitats together with associated cultural values and traditional natural resource management systems. They are generally large, with most of the area in a natural condition, where a proportion is under sustainable natural resource management and where low-level non-industrial use of natural resources compatible with nature conservation is seen as one of the main aims of the area.
- 1 : 50,000 scale Survey of India toposheet is divided into 36 grids further divided into 4 sub-grids, forming the basic sampling units. Two of these sub-grids are randomly selected and corresponding sub-grids in all the grids are selected to form the sample. The intersection of diagonals of such sub-grids are marked as center of plot on the map. At the center of selected subgrid a plot of 0.1 ha area is laid out in each such grid and data are collected from the plots falling in forest area only.
- For collecting data on soil, forest floor (humus & litter carbon), sub-plots of 1m x 1m are laid at each corner within the 0.1 ha plot.
- The data regarding herbs and shrubs (including regeneration) are collected from four square plots of 1m x 1m and 3m x 3m respectively. These plots are laid out at 30 meters from the centre of 0.1 ha plot in all four directions along diagonals in non-hilly area and along trails in hilly areas.
- Nearly two-thirds of the world’s ocean lies in areas beyond national jurisdiction (ABNJ), which are home to unique species and ecosystems
- Fragmented legal frameworks leave biodiversity in ABNJ vulnerable to growing threats
- The degradation of biodiversity in ABNJ affects the ocean’s capacity to provide resources necessary for human survival
- Negotiations are underway to create a new international instrument under the UN Convention on the Law, which would help close the existing ABNJ governance gap
- A new international instrument can provide a global framework for marine protected areas in ABNJ, ensure states assess impacts of potentially harmful activities, and facilitate inclusive scientific research that enables the equitable sharing of benefits from marine genetic resources.
- Natural World Heritage sites are globally recognised as the most significant protected areas on Earth
- These sites provide life-supporting benefits to millions of people – 90% of sites provide jobs, two-thirds are crucial sources of water and about half help prevent natural disasters such as floods or landslides
- Natural World Heritage sites are under increasing pressure from climate change, infrastructure development, mining, poaching and other threats
- To protect sites from threats, investment in their protection and management is urgently needed. Closely monitoring the status of sites, World Heritage-specific biodiversity targets, and adopting IUCN Green List standards for site management can also help
- These sites are a litmus test for our ability as a conservation community to protect biodiversity and pass on nature’s treasures to the next generation
- Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m
- Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent
- The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered
- Environmental impact assessments, effective regulation and mitigation strategies are needed to limit the impacts of deep-sea mining
- Comprehensive baseline studies are needed to improve our understanding of the deep sea
