Their management, governance and conservation however remain neglected not because of awareness but due to lack of capacity and complexities involved in their assessment of management needs. Wetlands contributes a lot to the benefits of ecosystem and environment as a whole by providing numerous ecological goods and services but remain under tremendous threat, owing to human interferences e.g., agricultural intensification, rapid urbanization, industrialization, decline in the hydrological, economic and ecological functions they perform and thus their area shrink over the period of time and sometimes may leads to collapsing of wetlands. Wetlands, the most productive system, categorized as Protected Areas in India are mostly governed by the Wildlife Protection Act of 1972. Central Government has also published Wetlands (Conservation and Management) Rules, 2016 to regulate activities within wetlands in India. A common feature of all wetlands is that they are having two common characteristics: Water or ice and earth. A wetland may be found in Coasts, estuaries, flood plains or swamps or marshes or can be observed as shallow lakes. Biodiversity studies on aquatic eco systems are mostly restricted to a few charismatic fish species, aquatic plants, water birds which is an impediment to the conservation of wetlands. This module on Wetland Management and Conservation shall focus on the needs and approaches to Wetland management and their conservation in India.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\"><strong style=\"text-align: initial;font-size: 1em\">I.

Naturally occurring wetlands may occur in many different forms e.g., Inland wetlands and Coastal wetlands. Inland wetlands may also be grouped as Himalayan wetlands and Indo-Gangetic wetlands. Himalayan wetlands includes Ladhak and Zanskar; Kashmir valley; Central Himalayas and Eastern Himalayas. Indo-Gangetic wetlands extending from river Indus in west to Brahmaputra in east. This also includes wetlands of Himalayan Terai and Indo-gangetic plans.<\/p>\r\n&nbsp;\r\n\r\nTwo categories (Inland wetlands and Coastal wetlands) further can be distinguished further broadly as<strong>:<\/strong>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\"><strong><em>Natural inland wetlands <\/em><\/strong>include: lakes, ponds, cut-off meander, high altitude wetlands, riverine wetlands, waterlogged areas, rivers and streams (Fig. 1).<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\"><strong><em>Man-made inland wetlands <\/em><\/strong>include: surface reservoirs, tanks, water logged areas, and salt pans<strong>.<\/strong><\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\"><strong><em>Natural coastal wetlands <\/em><\/strong>include: lagoons, creeks, sand beach, mud flats, salt marsh, mangroves, and coral reefs.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\"><strong><em>Man-made coastal wetlands <\/em><\/strong>include: salt pan and aquaculture ponds.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\">A cycle of wetting and drying is necessary for some wetlands to be healthy and sustained. Wetlands that dry out periodically can be the most biologically diverse wetlands [Oates, 1994]. Advantage of this natural wetting and drying cycle is that it changes pH levels of soils and leads to increase in availability of nutrients to plants [Mitsch &amp; Gosselink, 2000]. It is worth noting that re-flooding of a dry wetland also helps production of plant material which can be good food to various insects and animals [DNRE, 1997]. Hydrological conditions also affect nutrient cycling. Wetlands that have water flowing through them or in pulses have highest rate of nutrient cycling [Mitsch &amp; Gosselink, 2000].<\/p>\r\n&nbsp;\r\n\r\n<img class=\"aligncenter size-full wp-image-493\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312.png\" alt=\"\" width=\"648\" height=\"429\" \/>\r\n\r\n<\/div>\r\n<div>\r\n\r\n<strong>III.\u00a0 <\/strong><strong>Wetland Ecology (Vegetation, Soils, Flora and Fauna) Wetland Vegetation<\/strong>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\">Wetland plant species often exhibit distinct adaptations that allow a greater tolerance and survival in wetland areas.

Soils can be a reflection of the physical processes occurring in the wetland (for example, water inflow, water chemistry, filtering of pollutants). Wetland soils impact directly on other wetland characteristics (e.g. water quality, fauna, vegetation) [EPA, 2006]. Soils found in wetland areas (or areas that were once wetlands) typically have distinct properties that allow some form of identification and understanding of current or previous inundation regimes [Dear &amp; Svensson, 2007]. General soil indicators that are used to identify a wetland soil are:<\/p>\r\n\u2022\u00a0 accumulation of organic matter (e.g. peat)\r\n\r\n\u2022\u00a0 gleyed (greenish-blue-grey) soil colours\r\n\r\n\u2022\u00a0 soil mottling (the presence of more than one soil colour in the same soil horizon)\r\n\r\n\u2022\u00a0 iron or manganese segregations\r\n\r\n\u2022\u00a0 oxidising root channels and soil pore linings\r\n\r\n\u2022\u00a0 reduction of sulfur and carbon (e.g. acid sulfate soil) [EPA, 2006].\r\n\r\n&nbsp;\r\n\r\n<strong>IV. Wetland Importance and Threats<\/strong>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\">Wetlands cover an utmost significant area of planet Earth. On a global estimate this area is 1280 million hectares (i.e., equivalent to approximately 9% of land surface). India currently has 26 sites designated as Wetlands of International Importance (Ramsar Sites), with a surface area of 689,131 hectares (<strong>Table 1<\/strong>) [Shabbir, 2016]. It is estimated that wetland cover approximately on an estimated of 1-5% of the geographical area in India, and it is also an estimate that this area support approximately one-fifth of the known biodiversity [SAC, 2011]. Geographical extent of wetlands in India is well distributed extending from Himalayas to Deccan plateau [Bassi et. al., 2014]. Proportionately, Gujarat has the highest geographical area proportion (17.5%) with Mizoram maintain\u00a0<span style=\"font-size: 1em;text-align: initial\">the lowest proportion (0.66%). In Union Territories in India, Lakshadweep has the highest geographical area proportion under wetlands (around 96%) and Chandigarh has the least geographical area proportion (3%) of geographical area under wetlands [Bassi et. al., 2014]. As per an estimate India have about 757.06 thousand wetlands covering a total wetland area of 15.3mha. In India wetland category-wise can be understood as inland wetlands accounts for 69%, coastal wetlands 27%, and other wetlands (smaller than 2.25 ha) 4% [SAC, 2011]. In all these categories, natural coastal wetlands have the largest area [Bassi et. al., 2014].<\/span><\/p>\r\n\r\n<\/div>\r\n<div>\r\n\r\n<img class=\"aligncenter size-full wp-image-494\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313.png\" alt=\"\" width=\"669\" height=\"600\" \/>\r\n\r\n<img class=\"aligncenter size-full wp-image-495\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314.png\" alt=\"\" width=\"634\" height=\"154\" \/>\r\n\r\n<\/div>\r\n<div>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\">Wetlands are considered amongst the most productive ecosystems on the Earth [Germandi et. al., 2008]. Wetland are important for human existence, social and cultural diversities, ecosystem health and maintaining biodiversity by being natural buffer for natural disasters, Kidney of landscape, Biological supermarket and liquid Assets [FMS Handbook, 2011]. These provide nourishment to dwelling flora and fauna [Germandi et. al., 2008]. Major services by these wetlands are maintaining nutrient balance, biodiversity maintenance, flood control, retention of toxins and pollutants, groundwater recharge and carbon sequestration [Turner et. al., 2000] along with silt capture, water for irrigation, aquaculture, fisheries, human domestic and livestock consumption. Presents various services and benefits that are and can be derived from our Wetlands are mentioned in Table 2. This exhibits the sincere importance of wetlands as an essential component of our ecosystem and Environment as a whole.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\">There are various ways Wetlands support human\u2019s well-being, e.g., wetlands act as kidney \u2018kidneys of landscape\u2019; since these ecosystem receive inflow of water and waste from various upstream sources. Wetlands help in stabilizing water supplies, they cleanse polluted waters, along-with protect shorelines and most importantly recharge groundwater aquifers. Wetlands are also considered \u2018biological supermarkets\u2019 [www.sandrp.wordpress.com, 2017] as well, due to availability of extensive food chain and biological diversity in wetlands. Wetlands, being vital for human existence, maintain a highly productive and important portion of our natural wealth and \u201cliquid assets\u201d [www.sandrp.wordpress.com, 2017], along with have special attributes to cultural heritage for humanity. Despite their tremendous value for extending food security for humans, life support for a range of plants and animals (biodiversity) and water content of area, where they are found available, wetlands still are among one of the most rapidly degrading ecosystems.<\/p>\r\n<img class=\"aligncenter size-full wp-image-496\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315.png\" alt=\"\" width=\"564\" height=\"640\" \/>\r\n\r\n<img class=\"aligncenter size-full wp-image-497\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316.png\" alt=\"\" width=\"566\" height=\"143\" \/>\r\n\r\n<\/div>\r\n<div>\r\n\r\n<strong>\u00a0<\/strong>\r\n<p style=\"text-align: justify\">Various threats that are identified for wetland sustenance are natural system modification, Human settlements (non-agricultural), biological resource use, pollution from different sources, agriculture and aquaculture, invasive and other problematic species and genes, transportation and service corridors, water regulation, human intrusion and disturbances, climate change and stressful weather, energy production and mining Geological events. Intense grazing and uncontrolled fishing are another threats to wetlands in our country. Another type of threats are encroachment of reservoir area for various activities for example, urban development, excessive diversion of water for agriculture etc. [Verma, 2001]. Major threat is loss wetlands by human intervention. Loss of wetland in India can be divided into two broad groups i.e., acute wetland losses and chronic wetland losses. Abrupt change in ecosystem or wetland e.g., filling up of water covered areas with soil is considered as acute loss whereas the example of chronic loss can be a slow and gradual elimination of forest cover from the wetland with subsequent erosion and filling up by sediments in the wetlands over period of time, say, many decades. It is worth noting, in reference to the wetland conservation that due to activities like agriculture, dam construction and other activities approx 5000km2 of wetlands are lost annually [McAllister et. al., 2001]. Wetland processes that should be managed or protected include:<\/p>\r\n\u2022\u00a0 hydrology\r\n\r\n\u2022\u00a0 food webs\r\n\r\n\u2022\u00a0 habitats\r\n\r\n\u2022\u00a0 nutrient cycling\r\n\r\n\u2022\u00a0 sediment trapping and stabilization\r\n\r\n<strong>\u00a0<\/strong>\r\n\r\nMultiple-use water services (including Flood control)\r\n\r\n&nbsp;\r\n\r\n<\/div>\r\n<div>\r\n\r\n&nbsp;\r\n\r\n<strong>V.WETLAND CONSERVATION:<\/strong>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\">Healthy and sustainable wetlands are must for a vast country like India hence conservation is the only key to it. Wetlands are a vital part of our waterways and contribute to the health of our coastal resources (such as sea grass beds, fisheries production) by improving the quality of water flowing from the catchments to the sea. Loss of any interlinked component in ecosystem is not a positive sign for health sustenance. It can be understood with a relation [Footelee et. al.,1996] e.g., in India, loss of 1Km2 of wetlands with higher population will have much greater impacts than loss of 1Km2 of wetlands in low population areas of abundant wetlands [Wylynko,1999]. It is interesting to understand that for sustained conservation of wetlands inflow and outflow of water from different source plays an important role. e.g., main types of inflows can be groundwater, rainfall, flooding rivers, tidal influences and surface flows (e.g. crops-farm runoff and irrigation tail-water) etc. Main types of outflows from a wetland can be evaporation from standing surface or running water, the seepage to ground-water (aquifer recharge), water evaporated to atmosphere by plants (called evapo-transpiration), water held in soils and sediments, overland or channel flows.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\">In terms of Carbon storage and sequestration wetlands plays a miraculously incredible role. Sediments in wetland act as long term stores of carbon while biomass (plants, bacteria, fungi and animals) and dissolved components in wetland waters (surface and groundwater) act as short term C-storage [Pant et. al., 2003]. Wetland may be the contributor of global methane emissions, but they contains highest carbon density (among terrestrial ecosystems) with greater potentials for additional C-sequestration [Pant et. al.,2003], based on different studies, during survey, it can be estimated that soils and organic matter in wetlands may contain 200 times more carbon than its vegetation, hence it is important in reference with wetlands conservation to avoid removing soil beneath water surface. IPCC, 2000 have estimated that restored wetlands\u2019 (in over 50 year periods) carbon sequestration potential is about 0.4 tonnes C\/ha\/year [IPCC, 2000]. Mangroves are able to sequester approx 1.5 metric tonne of C\/ha\/year [Kathiresan &amp; Thakur, 2008; http:\/\/mangroveactionproject.org, 2017]. Wetlands function as net sequesters or producers of GHGs, this sequestration characteristic depends on their bio-geo-chemical processes and hydrology [Bassi et. al., 2014; Lisha, 2017].<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\">Awareness is another important tool for achieving sustainable success in most of environment systems and conservation related activities. The experts, policy makers and professionals with\u00a0<span style=\"font-size: 1em;text-align: initial\">advance knowledge on Wetlands must bring forward programs, seminars, open discussions etc among general public especially those living in vicinity and those who can be interested parties in dealing and protecting wetlands.<\/span><\/p>\r\n\r\n<\/div>\r\n<div>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\">Self rejuvenation by nature is another strategy for wetland conservation. Nature has capacity to rejuvenate its natural systems, considering system is left aloof from any interference other than Nature by itself. Wetlands are threatened by human interference e.g., degradation and reclamation of the wetland area. Degradation can be due to activities like drainage of water (clean and wastewater), landfill, pollution, alteration in hydrology, over-exploitation that leads to loss of biodiversity and disruption in ecosystem services provided by them [www.moef.nic.in, 2017]. Wetlands slow the passage of water and encourage the deposition of nutrients and sediments thereby improving water quality downstream. Wetlands are natural buffers and act as shield against increasing risk of floods, droughts and tropical cyclones. In addition, these ecosystem acts as sponges by storing peak rainfall and releasing water gradually during lean season [https:\/\/sandrp.wordpress.com, 2017]. Another important conservation strategy can be indepth study of aquatic Eco-system of these Bio-diverse wetlands without restriction to a few economical beneficial flora-fauna namely, fish species, aquatic plants, water birds that are identified in an around these wetland.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\">Major step in Wetlands Conservation Programs may include inventory &amp; mapping of wetland types, locations and associated regional ecosystems (REs); mapping of wetlands feeding river courses; water resources management; flora and fauna survey and inventorisation including habitat mapping, Remote Sensing or GIS based mapping of interconnectivity of wetlands. Maintaining Wetlands will sustainably delivers a diverse and wider range of important services for example, water-purification, recreational activities &amp; opportunities, coastal protection, water-supply, aquatic fauna including fish and fiber, and increasingly, tourism) that are vital for human well-being (Fig 2). Fig 2 explains assessment basic steps for wetland conservation that may include, Inventory of Class\/type of wetland; Status of vegetation, mapping etc. Further it is important to conserve wetland against degradation, de-vegetation, eutrophication, climate change and similar lethal phenomenon for water-bodies. It is expected that increasing phenomenon of global climate change will further exacerbate the loss of terrestrial water storage capacity of wetland leading to sea level rise; degradation of wetland\u00a0<span style=\"font-size: 1em;text-align: initial\">biodiversity including species (e.g., migratory species) that cannot relocate or migrate since they rely more or less on existing wetlands for different stages of their life cycle.<\/span><\/p>\r\n<img class=\"aligncenter size-full wp-image-498\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317.png\" alt=\"\" width=\"564\" height=\"284\" \/>\r\n\r\n<\/div>\r\n<div>\r\n\r\n&nbsp;\r\n<p style=\"text-align: justify\">Seriousness and accountability for implementation and conformity among government policies in all related areas of development, planning and economics of environment nature conservation, can be policy related steps to avoid deterioration of these wetlands hence conservation can be expected. In addition, good governance and management of these wetlands can also leads to significant conservation of these water-bodies called wetlands. As a part of their Corporate Social Responsibilities towards society and Environment, Industrial establishments including Private organizations, corporate houses may initiate various programs with employees and community participation to conserve these wetlands.<\/p>\r\n&nbsp;\r\n<p style=\"text-align: justify\">Impacts of climate change, hydrological regime alteration also adversely impacts wetlands hence general steps to avoid climate change and hydrology of ecosystem locally and globally may support conservation as well. For example, locally burning of trashes, setting up fires in landfills sites, forests, moderate use of automobiles to avoid combustion of fossil fuels, explosive and crackers on festivities, less use of fertilizers, chemicals- insecticides pesticides etc in crop fields, conservation of\u00a0<span style=\"font-size: 1em;text-align: initial\">ground water, maintaining good health of riverine systems may support wetlands conservation as well. Globally conserving water bodies and their hydrology, sustainable management of forests, avoiding combustion of fossil fuels, avoiding chemicals spraying on crops to eliminate pest and insects, control of pollution and leakages from landfill or contaminated sites to water-bodies, ban on encroachment of water bodies etc. may support wetlands conservation.<\/span><\/p>\r\n\r\n<\/div>\r\n<div>\r\n\r\n&nbsp;\r\n\r\n<strong>V.

Their management, governance and conservation however remain neglected not because of awareness but due to lack of capacity and complexities involved in their assessment of management needs. Wetlands contributes a lot to the benefits of ecosystem and environment as a whole by providing numerous ecological goods and services but remain under tremendous threat, owing to human interferences e.g., agricultural intensification, rapid urbanization, industrialization, decline in the hydrological, economic and ecological functions they perform and thus their area shrink over the period of time and sometimes may leads to collapsing of wetlands. Wetlands, the most productive system, categorized as Protected Areas in India are mostly governed by the Wildlife Protection Act of 1972. Central Government has also published Wetlands (Conservation and Management) Rules, 2016 to regulate activities within wetlands in India. A common feature of all wetlands is that they are having two common characteristics: Water or ice and earth. A wetland may be found in Coasts, estuaries, flood plains or swamps or marshes or can be observed as shallow lakes. Biodiversity studies on aquatic eco systems are mostly restricted to a few charismatic fish species, aquatic plants, water birds which is an impediment to the conservation of wetlands. This module on Wetland Management and Conservation shall focus on the needs and approaches to Wetland management and their conservation in India.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\"><strong style=\"text-align: initial;font-size: 1em\">I.

This also includes wetlands of Himalayan Terai and Indo-gangetic plans.<\/p>\n<p>&nbsp;<\/p>\n<p>Two categories (Inland wetlands and Coastal wetlands) further can be distinguished further broadly as<strong>:<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\"><strong><em>Natural inland wetlands <\/em><\/strong>include: lakes, ponds, cut-off meander, high altitude wetlands, riverine wetlands, waterlogged areas, rivers and streams (Fig. 1).<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\"><strong><em>Man-made inland wetlands <\/em><\/strong>include: surface reservoirs, tanks, water logged areas, and salt pans<strong>.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\"><strong><em>Natural coastal wetlands <\/em><\/strong>include: lagoons, creeks, sand beach, mud flats, salt marsh, mangroves, and coral reefs.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\"><strong><em>Man-made coastal wetlands <\/em><\/strong>include: salt pan and aquaculture ponds.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">A cycle of wetting and drying is necessary for some wetlands to be healthy and sustained. Wetlands that dry out periodically can be the most biologically diverse wetlands [Oates, 1994]. Advantage of this natural wetting and drying cycle is that it changes pH levels of soils and leads to increase in availability of nutrients to plants [Mitsch &amp; Gosselink, 2000]. It is worth noting that re-flooding of a dry wetland also helps production of plant material which can be good food to various insects and animals [DNRE, 1997]. Hydrological conditions also affect nutrient cycling. Wetlands that have water flowing through them or in pulses have highest rate of nutrient cycling [Mitsch &amp; Gosselink, 2000].<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-493\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312.png\" alt=\"\" width=\"648\" height=\"429\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312.png 648w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312-300x199.png 300w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312-65x43.png 65w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312-225x149.png 225w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-312-350x232.png 350w\" sizes=\"auto, (max-width: 648px) 100vw, 648px\" \/><\/p>\n<\/div>\n<div>\n<p><strong>III.\u00a0 <\/strong><strong>Wetland Ecology (Vegetation, Soils, Flora and Fauna) Wetland Vegetation<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Wetland plant species often exhibit distinct adaptations that allow a greater tolerance and survival in wetland areas.

Soils can be a reflection of the physical processes occurring in the wetland (for example, water inflow, water chemistry, filtering of pollutants). Wetland soils impact directly on other wetland characteristics (e.g. water quality, fauna, vegetation) [EPA, 2006]. Soils found in wetland areas (or areas that were once wetlands) typically have distinct properties that allow some form of identification and understanding of current or previous inundation regimes [Dear &amp; Svensson, 2007].

Wetland Importance and Threats<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Wetlands cover an utmost significant area of planet Earth. On a global estimate this area is 1280 million hectares (i.e., equivalent to approximately 9% of land surface). India currently has 26 sites designated as Wetlands of International Importance (Ramsar Sites), with a surface area of 689,131 hectares (<strong>Table 1<\/strong>) [Shabbir, 2016]. It is estimated that wetland cover approximately on an estimated of 1-5% of the geographical area in India, and it is also an estimate that this area support approximately one-fifth of the known biodiversity [SAC, 2011]. Geographical extent of wetlands in India is well distributed extending from Himalayas to Deccan plateau [Bassi et. al., 2014]. Proportionately, Gujarat has the highest geographical area proportion (17.5%) with Mizoram maintain\u00a0<span style=\"font-size: 1em;text-align: initial\">the lowest proportion (0.66%). In Union Territories in India, Lakshadweep has the highest geographical area proportion under wetlands (around 96%) and Chandigarh has the least geographical area proportion (3%) of geographical area under wetlands [Bassi et. al., 2014]. As per an estimate India have about 757.06 thousand wetlands covering a total wetland area of 15.3mha. In India wetland category-wise can be understood as inland wetlands accounts for 69%, coastal wetlands 27%, and other wetlands (smaller than 2.25 ha) 4% [SAC, 2011]. In all these categories, natural coastal wetlands have the largest area [Bassi et. al., 2014].<\/span><\/p>\n<\/div>\n<div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-494\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313.png\" alt=\"\" width=\"669\" height=\"600\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313.png 669w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313-300x269.png 300w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313-65x58.png 65w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313-225x202.png 225w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-313-350x314.png 350w\" sizes=\"auto, (max-width: 669px) 100vw, 669px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-495\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314.png\" alt=\"\" width=\"634\" height=\"154\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314.png 634w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314-300x73.png 300w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314-65x16.png 65w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314-225x55.png 225w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-314-350x85.png 350w\" sizes=\"auto, (max-width: 634px) 100vw, 634px\" \/><\/p>\n<\/div>\n<div>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Wetlands are considered amongst the most productive ecosystems on the Earth [Germandi et. al., 2008].

These provide nourishment to dwelling flora and fauna [Germandi et. al., 2008]. Major services by these wetlands are maintaining nutrient balance, biodiversity maintenance, flood control, retention of toxins and pollutants, groundwater recharge and carbon sequestration [Turner et. al., 2000] along with silt capture, water for irrigation, aquaculture, fisheries, human domestic and livestock consumption. Presents various services and benefits that are and can be derived from our Wetlands are mentioned in Table 2. This exhibits the sincere importance of wetlands as an essential component of our ecosystem and Environment as a whole.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">There are various ways Wetlands support human\u2019s well-being, e.g., wetlands act as kidney \u2018kidneys of landscape\u2019; since these ecosystem receive inflow of water and waste from various upstream sources. Wetlands help in stabilizing water supplies, they cleanse polluted waters, along-with protect shorelines and most importantly recharge groundwater aquifers. Wetlands are also considered \u2018biological supermarkets\u2019 [www.sandrp.wordpress.com, 2017] as well, due to availability of extensive food chain and biological diversity in wetlands. Wetlands, being vital for human existence, maintain a highly productive and important portion of our natural wealth and \u201cliquid assets\u201d [www.sandrp.wordpress.com, 2017], along with have special attributes to cultural heritage for humanity. Despite their tremendous value for extending food security for humans, life support for a range of plants and animals (biodiversity) and water content of area, where they are found available, wetlands still are among one of the most rapidly degrading ecosystems.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-496\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315.png\" alt=\"\" width=\"564\" height=\"640\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315.png 564w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315-264x300.png 264w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315-65x74.png 65w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315-225x255.png 225w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-315-350x397.png 350w\" sizes=\"auto, (max-width: 564px) 100vw, 564px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-497\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316.png\" alt=\"\" width=\"566\" height=\"143\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316.png 566w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316-300x76.png 300w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316-65x16.png 65w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316-225x57.png 225w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-316-350x88.png 350w\" sizes=\"auto, (max-width: 566px) 100vw, 566px\" \/><\/p>\n<\/div>\n<div>\n<p><strong>\u00a0<\/strong><\/p>\n<p style=\"text-align: justify\">Various threats that are identified for wetland sustenance are natural system modification, Human settlements (non-agricultural), biological resource use, pollution from different sources, agriculture and aquaculture, invasive and other problematic species and genes, transportation and service corridors, water regulation, human intrusion and disturbances, climate change and stressful weather, energy production and mining Geological events. Intense grazing and uncontrolled fishing are another threats to wetlands in our country. Another type of threats are encroachment of reservoir area for various activities for example, urban development, excessive diversion of water for agriculture etc. [Verma, 2001]. Major threat is loss wetlands by human intervention. Loss of wetland in India can be divided into two broad groups i.e., acute wetland losses and chronic wetland losses. Abrupt change in ecosystem or wetland e.g., filling up of water covered areas with soil is considered as acute loss whereas the example of chronic loss can be a slow and gradual elimination of forest cover from the wetland with subsequent erosion and filling up by sediments in the wetlands over period of time, say, many decades. It is worth noting, in reference to the wetland conservation that due to activities like agriculture, dam construction and other activities approx 5000km2 of wetlands are lost annually [McAllister et. al., 2001]. Wetland processes that should be managed or protected include:<\/p>\n<p>\u2022\u00a0 hydrology<\/p>\n<p>\u2022\u00a0 food webs<\/p>\n<p>\u2022\u00a0 habitats<\/p>\n<p>\u2022\u00a0 nutrient cycling<\/p>\n<p>\u2022\u00a0 sediment trapping and stabilization<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p>Multiple-use water services (including Flood control)<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<div>\n<p>&nbsp;<\/p>\n<p><strong>V.WETLAND CONSERVATION:<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Healthy and sustainable wetlands are must for a vast country like India hence conservation is the only key to it. Wetlands are a vital part of our waterways and contribute to the health of our coastal resources (such as sea grass beds, fisheries production) by improving the quality of water flowing from the catchments to the sea. Loss of any interlinked component in ecosystem is not a positive sign for health sustenance. It can be understood with a relation [Footelee et. al.,1996] e.g., in India, loss of 1Km2 of wetlands with higher population will have much greater impacts than loss of 1Km2 of wetlands in low population areas of abundant wetlands [Wylynko,1999]. It is interesting to understand that for sustained conservation of wetlands inflow and outflow of water from different source plays an important role. e.g., main types of inflows can be groundwater, rainfall, flooding rivers, tidal influences and surface flows (e.g. crops-farm runoff and irrigation tail-water) etc. Main types of outflows from a wetland can be evaporation from standing surface or running water, the seepage to ground-water (aquifer recharge), water evaporated to atmosphere by plants (called evapo-transpiration), water held in soils and sediments, overland or channel flows.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">In terms of Carbon storage and sequestration wetlands plays a miraculously incredible role. Sediments in wetland act as long term stores of carbon while biomass (plants, bacteria, fungi and animals) and dissolved components in wetland waters (surface and groundwater) act as short term C-storage [Pant et. al., 2003]. Wetland may be the contributor of global methane emissions, but they contains highest carbon density (among terrestrial ecosystems) with greater potentials for additional C-sequestration [Pant et. al.,2003], based on different studies, during survey, it can be estimated that soils and organic matter in wetlands may contain 200 times more carbon than its vegetation, hence it is important in reference with wetlands conservation to avoid removing soil beneath water surface. IPCC, 2000 have estimated that restored wetlands\u2019 (in over 50 year periods) carbon sequestration potential is about 0.4 tonnes C\/ha\/year [IPCC, 2000]. Mangroves are able to sequester approx 1.5 metric tonne of C\/ha\/year [Kathiresan &amp; Thakur, 2008; http:\/\/mangroveactionproject.org, 2017]. Wetlands function as net sequesters or producers of GHGs, this sequestration characteristic depends on their bio-geo-chemical processes and hydrology [Bassi et. al., 2014; Lisha, 2017].<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Awareness is another important tool for achieving sustainable success in most of environment systems and conservation related activities. The experts, policy makers and professionals with\u00a0<span style=\"font-size: 1em;text-align: initial\">advance knowledge on Wetlands must bring forward programs, seminars, open discussions etc among general public especially those living in vicinity and those who can be interested parties in dealing and protecting wetlands.<\/span><\/p>\n<\/div>\n<div>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Self rejuvenation by nature is another strategy for wetland conservation. Nature has capacity to rejuvenate its natural systems, considering system is left aloof from any interference other than Nature by itself. Wetlands are threatened by human interference e.g., degradation and reclamation of the wetland area. Degradation can be due to activities like drainage of water (clean and wastewater), landfill, pollution, alteration in hydrology, over-exploitation that leads to loss of biodiversity and disruption in ecosystem services provided by them [www.moef.nic.in, 2017]. Wetlands slow the passage of water and encourage the deposition of nutrients and sediments thereby improving water quality downstream. Wetlands are natural buffers and act as shield against increasing risk of floods, droughts and tropical cyclones. In addition, these ecosystem acts as sponges by storing peak rainfall and releasing water gradually during lean season [https:\/\/sandrp.wordpress.com, 2017]. Another important conservation strategy can be indepth study of aquatic Eco-system of these Bio-diverse wetlands without restriction to a few economical beneficial flora-fauna namely, fish species, aquatic plants, water birds that are identified in an around these wetland.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Major step in Wetlands Conservation Programs may include inventory &amp; mapping of wetland types, locations and associated regional ecosystems (REs); mapping of wetlands feeding river courses; water resources management; flora and fauna survey and inventorisation including habitat mapping, Remote Sensing or GIS based mapping of interconnectivity of wetlands. Maintaining Wetlands will sustainably delivers a diverse and wider range of important services for example, water-purification, recreational activities &amp; opportunities, coastal protection, water-supply, aquatic fauna including fish and fiber, and increasingly, tourism) that are vital for human well-being (Fig 2). Fig 2 explains assessment basic steps for wetland conservation that may include, Inventory of Class\/type of wetland; Status of vegetation, mapping etc. Further it is important to conserve wetland against degradation, de-vegetation, eutrophication, climate change and similar lethal phenomenon for water-bodies. It is expected that increasing phenomenon of global climate change will further exacerbate the loss of terrestrial water storage capacity of wetland leading to sea level rise; degradation of wetland\u00a0<span style=\"font-size: 1em;text-align: initial\">biodiversity including species (e.g., migratory species) that cannot relocate or migrate since they rely more or less on existing wetlands for different stages of their life cycle.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-498\" src=\"http:\/\/esp05.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317.png\" alt=\"\" width=\"564\" height=\"284\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317.png 564w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317-300x151.png 300w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317-65x33.png 65w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317-225x113.png 225w, https:\/\/ebooks.inflibnet.ac.in\/esp05\/wp-content\/uploads\/sites\/166\/2019\/03\/1-317-350x176.png 350w\" sizes=\"auto, (max-width: 564px) 100vw, 564px\" \/><\/p>\n<\/div>\n<div>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Seriousness and accountability for implementation and conformity among government policies in all related areas of development, planning and economics of environment nature conservation, can be policy related steps to avoid deterioration of these wetlands hence conservation can be expected. In addition, good governance and management of these wetlands can also leads to significant conservation of these water-bodies called wetlands. As a part of their Corporate Social Responsibilities towards society and Environment, Industrial establishments including Private organizations, corporate houses may initiate various programs with employees and community participation to conserve these wetlands.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">Impacts of climate change, hydrological regime alteration also adversely impacts wetlands hence general steps to avoid climate change and hydrology of ecosystem locally and globally may support conservation as well. For example, locally burning of trashes, setting up fires in landfills sites, forests, moderate use of automobiles to avoid combustion of fossil fuels, explosive and crackers on festivities, less use of fertilizers, chemicals- insecticides pesticides etc in crop fields, conservation of\u00a0<span style=\"font-size: 1em;text-align: initial\">ground water, maintaining good health of riverine systems may support wetlands conservation as well. Globally conserving water bodies and their hydrology, sustainable management of forests, avoiding combustion of fossil fuels, avoiding chemicals spraying on crops to eliminate pest and insects, control of pollution and leakages from landfill or contaminated sites to water-bodies, ban on encroachment of water bodies etc. may support wetlands conservation.<\/span><\/p>\n<\/div>\n<div>\n<p>&nbsp;<\/p>\n<p><strong>V.

In Fig 3 Ramsar sites, the wetlands of International importance that have been identified globally [De Groot et. al., 2006] have been presented. In Fig 3 percent of total Ramsar sites with their numbers globally [De Groot et. al., 2006] have been also presented in parenthesis. There are almost 26 Ramsar sites spread across India (Fig 4).
