World Wetlands Day observed
World Wetlands Day is celebrated on the second day of February every year. The day marks the adoption of the Convention on Wetlands (Ramsar Convention) held in Iran in 1971. This day serves to the influence and positive production that Wetlands have had on the world and in terms brings communities together for the benefit of Mother Nature. This day, also raises global awareness because wetlands play a significant role not only in people but in the planet. Community protectors and environmental enthusiast all come together on this day to celebrate their love for nature through celebration, which recognizes what wetlands have done for not only us humans, but all sorts of organisms in this world.
This year the occasion is celebrated with the slogan “Protecting Wetlands for Our Common Future.” The theme underscores the urgency of bold action to protect these natural habitats for the welfare of all people – and so future generations can continue to benefit from all that wetlands provide.
Wetlands are areas where water is the primary factor controlling the environment and the associated plant and animal life. They occur where the water table is at or near the surface of the land, or where the land is covered by water. The Ramsar Convention takes a broad approach in determining the wetlands which come under its aegis. Under the text of the Convention (Article 1.1), wetlands are defined as: “areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres”. In addition, for the purpose of protecting coherent sites, the Article 2.1 provides that wetlands to be included in the Ramsar List of internationally important wetlands: “may incorporate riparian and coastal zones adjacent to the wetlands, and islands or bodies of marine water deeper than six metres at low tide lying within the wetlands”.
Wetlands provide tremendous economic benefits, for example: water supply (quantity and quality); fisheries (over two thirds of the world’s fish harvest is linked to the health of coastal and inland wetland areas); agriculture, through the maintenance of water tables and nutrient retention in floodplains; timber production; energy resources, such as peat and plant matter; wildlife resources; transport; and recreation and tourism opportunities. In addition, wetlands have special attributes as part of the cultural heritage of humanity: they are related to religious and cosmological beliefs, constitute a source of aesthetic inspiration, provide wildlife sanctuaries, and form the basis of important local traditions. These functions, values and attributes can only be maintained if the ecological processes of wetlands are allowed to continue functioning. Unfortunately, and in spite of important progress made in recent decades, wetlands continue to be among the world’s most threatened ecosystems, owing mainly to ongoing drainage, conversion, pollution, and over-exploitation of their resources.
Wetlands are among the world’s most diverse productive environments; cradles of biological diversity that provide the water and productivity upon which countless species of plants and animals depend for survival. Wetlands are indispensable for the countless benefits or “ecosystem services” that they provide humanity, ranging from freshwater supply, food and building materials, and biodiversity, to flood control, groundwater recharge, and climate change mitigation. Wetlands are also essential for biodiversity: though wetlands cover only around 6% of the Earth’s land surface, 40% of all plant and animal species live or breed in wetlands.
However, wetlands as the most threatened ecosystem. According to the World Heritage and Ramsar Conventions, 64% of the world’s wetlands have disappeared since the beginning of the last century. In most regions across the world, wetlands continue to decline compromising the benefits that wetlands provide to people. According to the Global Wetland Outlook, we lose wetlands three times faster than natural forests. Therefore, the conservation of wetlands is a vital task of humanity, which can help achieving the Sustainable Development Goals by 2030.
Moreover, wetlands are ecosystems where water is the primary factor controlling the environment and the associated plant and animal life. A broad definition of wetlands includes both freshwater and marine and coastal ecosystems such as all lakes and rivers, underground aquifers, swamps and marshes, wet grasslands, peatlands, oases, estuaries, deltas and tidal flats, mangroves and other coastal areas, coral reefs, and all human-made sites such as fishponds, rice paddies, reservoirs and saltpans.
These lands are critical to people and nature, given the intrinsic value of these ecosystems, and their benefits and services, including their environmental, climate, ecological, social, economic, scientific, educational, cultural, recreational and aesthetic contributions to sustainable development and human wellbeing.
Wetlands offer vital freshwater, hosting over 100,000 species. They sustain humanity, exemplified by rice grown on wetland paddies, a staple for three billion people, contributing to 20% of global food. Additionally, wetlands act as natural shock absorbers, mitigating rainfall impacts and lowering flood and storm surge risks.
Over time, human construction has led to various ecological problems affecting wetlands. Overpopulation and construction has led to a decrease in environmental conservation and in total has brought upon issues to these lands. Many wetlands are being lost and ecologists claim that human should recognize the dilemma before the loss of a natural filter and conserver of the world.
With an approximate area of 819,277 hectares (nearly 5% of the country’s area), Nepal homes 242 wetlands which are often considered as the most productive ecosystems of the world.
Nepal has 10 sites designated as Wetlands of International Importance (Ramsar Sites) with a surface area of 60, 561 hectares.
These diverse wetland ecosystems from tranquil high-altitude lakes to Terai grasslands represent global biodiversity hotspots hosting vital habitats for numerous endangered species while supporting wetland rice harvesting and storm protection ecosystem services benefiting Nepal’s population. Designated Ramsar sites like Rara Lake conserve rare endemic fish and migratory cranes while providing ecotourism jobs balancing conservation aims.
Nepal’s longstanding Ramsar Convention commitments safeguarding 60,000 wetland hectares through 10 designated Wetlands of International Importance sites protecting the country’s reputation as a proud haven for rare waterbirds, rhinos, dolphins, crocodiles, and apex Gharial species threatened by habitat erosion.
Nepal’s Koshi Tappu Wildlife Reserve, Rara Lake, Mai Pokhari, Phoksundo Lake, Bisahajari Lake, Ghodaghodi Lake, Gosainkunda Lake, Gokyo Lake, Jagdishpur Reservoir and Pokhara Valley and a group of nine lakes in the area are included in the Ramsar List. Relevant Government entities and various climate and environment institutions organized programmes like educational workshops, cleanliness drives, and expert seminars to celebrated the day in Nepal. The programme they conduct comprise awareness on ecological and economic wetland services like water filtration, flood control, and agrobiodiversity reliance of indigenous groups, conservation of flora and fauna, urging policy enhancements preventing degradation from encroachment, infrastructures.
