Introduction of land shaping techniques under low land situations	·         Alleviation of the problems of water logging and salinity build-up ·         Rain water harvesting to supply fresh irrigation water during scarcity period ·         Converting land from mono-cropping to multiple cropping round the year and enhancing crop production ·         Crop diversification and enhancing cropping intensity
River water dynamics, soil & water salinity, and sedimentation load at specified grid intervals	·         Will help in preparing spatial and temporal variability of soil salinity and other relevant parameters in relation to river water hydrology and sedimentation ·         Appropriate strategies to be adopted for regulating river water flow to minimize increase in soil salinity ·         Sedimentation load in relation to river water hydrology will suggest drainage problems particularly in the coastal lowlands
Working out demand and availability of coastal water sources for their optimal use	·         Demand and availability of coastal water from different river basins should be worked out and optimized for use under various domestic, agriculture and industrial sectors on watershed basis. The water budget so prepared should be aimed at: a) increasing crop productivity for every unit of water; b) increasing potential groundwater supply through artificial recharge methods; c) concentrating on economic activities where the value of water is very high; and d) getting water transfers from the water-rich basins.
Optimal use of surface and subsurface water for arresting salinization of soil	·         Use of subsurface water for large scale irrigation and other practices should be moderated or minimized through application of suitable ‘optimization models’ in order to arrest intrusion of aquifer containing saline water landward ·         For aquifer in the coastal alluvia the artificial recharge, which is estimated to be about 10-15 % of the rainfall amount may be   aimed instead at arresting salt water intrusion landward or pushing the zone further seawards, and thereby reversing any trend for landward movement.
Creation of Integrated water management facilities through water harvesting in the pond on community basis	·         Introduction of on-farm reservoir (OFR) technology for creating water resources and mitigation of drainage problems ·         Adoption of suitable flood protection and drainage measures ·         Enhancement of cropping intensity and food production ·         Create opportunities for inland fisheries and integrated farming practices
Conjunctive use of poor quality water along with harvested rain water	·         Multiple crop cultivation under scarcity of fresh water situation
Desalinated water use and alternate energy use for irrigation and other agricultural operations	·         Attempt should be made to explore production of desalinated water through distillation, reverse osmosis, and electrolysis, most of which are yet to be cost-effective though technologically sound. ·         Alternate energy sources, such as wind,  solar and wave, available in abundance along the coast should be harnessed,  in place of fossil fuel, through use of cost-effective technologies.
Construction of protective embankments	·         Prevention of frequent flooding and intrusion of saline water in the agricultural fields during high tides
Drainage improvement by proper leveling of crop fields and by installing appropriately designed sluice gates, and their proper maintenance	·         Enhancement of crop production and improved crop security ·         Sluice gates to drain out excess water and simultaneously to prevent intrusion of saline water into the cultivated fields
The dynamics of alluvial landscapes and natural sedimentation patterns that determine the nutrient and energy flows in coastal areas are increasingly being modified by human activities, in particular those that affect water flows (dams, increased water extraction, deviation of rivers) and erosion, especially due to deforestation. This prevents or slows down vertical accretion, thus aggravating salt water intrusion and impairing drainage conditions in riverine, delta or estuarine areas. It reduces or blocks sediment supply to the coast itself, which may give rise to the retreat of the coastline through wave erosion. Beach erosion is a growing problem and affects tourism revenue, especially in island nations.	·         Desiltation of river, estuaries and drainage channels will help improvement of drainage, prevention from salt water intrusion and flooding of land. ·         Beach erosion may be substantially reduced through appropriate measures against erosion ·         Human activities such as construction of dams, diversion of water flow thereby adversely affecting the river hydrology, unplanned extraction of water from the aquifer, deforestation, etc., which are mainly responsible for increasing trend in sedimentation, should be regulated

Goal # 10: Ecology and adoption to climate change
Adoption of such practices as conservation tillage, use of organic farming along with incorporation of organic residues and other materials such as biochar, appropriate land restoration & management practices, reduction of erosion, and optimal water use patterns like SRI in waterlogged rice cultivation are known for reduced emission of CH4 and N2O and thereby moderate climate change effects	§ Reduced climate change effects will help maintain ecology and productivity, and also moderate adverse threats due to natural hazards
Coastal waterlogged marshes are regarded as a rich source for carbon sink; therefore appropriate attention is required to estimate this valuable parameter with reference to different natural parameters prevalent in this ecosystem and preferably over a long period of time in the past through radiocarbon dating.	§ A study on this and its proper use will be very much helpful in ensuring sustenance in productivity and adaptation against climate change
Coastal ecosystem should be regarded as a rich repository of natural resources including plant and animal species	§ Abundance of natural resources and  their equilibrium developed and maintained over a long period of time is invaluable in ensuring sustenance in ecology vis-a-vis climate change and thereby withstand to a significant measure threats against natural disaster
Identifying intervention matrix of different technological, anthropological, natural & other climatic factors along with estimation of vulnerability index, and develop optimization guidelines for each coastal site. There should be an appropriate strategy to be worked out on optimum population density in the coastal ecosystem	§ Appropriate strategies and guidelines will ensure withstand in the long run damage against climate change for coastal and adjoining inland areas. § Optimum population density will ensure damage against natural disaster
Coral reefs cover < 0.5 % of the ocean floor and 90 % of the marine species are directly or indirectly dependent on them. About 20% of coral reefs have been destroyed in the last few decades and an additional 20% or more are severely degraded on a global scale. There is no proper estimate of the damage in the marine ecosystem in India. Among others coral bleaching, which results from rising ocean temperatures caused by climate change is also increasing and further threatens this valuable resource. Necessary action should be taken for estimating the damage and steps to prevent such damage especially in the wake of climate change.	§ Steps against damage of the coral reefs, a   highly valuable marine resource, will ensure to a significant extent maintain the aquatic species and sustain the ecological balance
The estuaries, regarded as “nurseries of the sea”, should be protected and maintained against environmental hazards and anthropological activities.	§ Most commercially important fish species spend some part of their life cycle in estuaries. Besides fish, many species of birds depend on estuaries for food and nesting areas. Marine mammals also use estuaries as feeding grounds and nurseries. All these marine organisms feed in estuaries because a healthy estuary produces between 4 and 10 times as much organic matter as a cornfield of the same size. Estuaries provide a wide range of habitats leading to a great diversity of marine life. Thus, maintenance of the estuaries will be very much helpful towards sustenance of the ecological balance.
The urban developments are taking up fertile agricultural land and leading to pollution of rivers, estuaries and seas by sewage as well as industrial and agricultural effluents. In turn, this is posing a threat to coastal ecosystems, their biological diversity, environmental regulatory functions and role in generating employment and food. Overuse of fertilizer can result in eutrophication, and in extreme cases, the creation of ‘dead zones’. Dead zones occur when excess nutrients—usually nitrogen and phosphorus—from agriculture or the burning of fossil fuels seep into the water system and fertilize blooms of algae along the coast. Besides, the occurrence of hypoxia in shallow coastal and estuarine areas has been increasing worldwide, most likely accelerated by anthropogenic activities.	§ Human activities, which now contribute more to the supply of fixed nitrogen each year than natural processes do, should be regulated particularly in the areas of use of fertilizer,  burning of fossil fuels, and surge in land clearing and deforestation. Thus, appropriate strategies should be developed to decrease the menace due to eutrophication, hypoxia and dead zones, which will help in maintaining the ecological balance of the ecosystem..
Goal # 11 Forecasting flood and natural hazards
Developing and validating a trans-continental forecasting system against flood and natural hazards	·         A system to be developed that may bring together operational meteorological forecasts with satellite and discharge data and a suite of hydrological models. ·         Network technologies should be perfected for rapid dissemination. ·         It should preferably be tested for validity in a trans-continental mode, and may be used as a template for flood forecasting also
