Seagrass distribution and its vulnerability in India

The coastal vegetation is of specialized nature, which grows under different conditions with one ecosystem linked to the other including the coral reefs. The vegetation can be classified into four groups 1. Marine algae or seaweeds 2. Seagrasses, 3. Mangroves and 4. Sanddune vegetation,which grows on a sandy shore beyond the highest high tide level. Seagrasses are submerged angiospermic monocotyledon plants. They are adapted to the marine environment and complete their life cycle underwater In contrast to other submerged marine plants (e.g. seaweeds), sea grasses flower, fruit and produce seeds. They also have true roots and internal system for the transport of gases and nutrient. They generally grow in shallow coastal water from the inter-tidal zone to depths up to 10m. In turbid estuarine environment, such as the Indian coast, where there is an enormous deposition of silt into the sea by major rivers, sea grasses are rarely encountered at depths below 10m. In less turbid areas, such as the Caribbean sea and Australian coast, sea grasses can be found at depths of 50m or more

“Garbage doesn’t have to be a dirty thing”

Waste Impact Trust is a NGO founded by Ms. Gayitri Handanahal who has served for 13 years in the social sector under diverse areas such as skill development among BPL Self Help Groups, Safe drinking water with the Naandi Foundation. For the last four years she has been working in Solid Waste Management. She conceptualized and coordinated a programme namely, “Reimagine Waste” as a series of Waste Hackathons in collaboration with the Centre for Product Design and Manufacturing (CPDM) at the Indian Institute of Science (IISc). These hackathons have specific themes on waste and are supported by corporates and institutions through 4-day events and the post hackathon activities. Hackathons provide a platform for creativity to find low cost, high impact solutions for day to day problems of waste management using technology. The unique aspect of these hackathons is that the vulnerable communities are part of the hacking teams and contribute to solutions from conception to prototyping to creating business plans

Mangrove ecosystem and its impact on fisheries

Mangrove formation is a tropical phenomenon confined to tropical coastal areas, and sometimes extends to sub-tropical or slightly beyond. Areas where mangroves occur include estuaries and marine shorelines. In comparison with the tropical rainforest biome which contains thousands of tree species, mangrove forests are less in diversity. But the ecosystem these trees create provides a home for a great variety of other organisms. Mangrove forests form an interface between marine and terrestrial environment

Instruments for siltation and sedimentation analysis

Land clearing and grading have adverse effects on lagoon, mangrove and other estuarine coastal ecosystems due to sediment transportation. Experiments have shown that the erosive power of water flowing with a velocity ‘V’, varies as ‘V2’ while the transporting ability of water increases to a velocity of ‘V6’. Sediments, which move as bed load at one section may be in suspension at another section. As the silt originates from the watershed, the characteristics of the catchment area such as it’s aerial extent, soil types, land slopes, vegetal cover and climatic conditions like temperature and intensity of rainfall have great significance in the sediment production in the form of sheet erosion, gully erosion and stream channel erosio

Solid waste management in Mangaluru

Mangaluru, the fourth largest city in Karnataka State is situated in the west coast of Southern India. It is the fast growing city in education, commerce and industry. The city with more than 5.5 lakh population faces the challenges of dealing with its solid waste. The rapid urbanization and changing lifestyles have led to the generation of huge amount of garbage and wastes in the urban areas. The initiative by Mangaluru City Corporation (MCC) could successfully collect the solid waste generated within Mangaluru City and process it at centralized processing plant at Pachanady of the City Corporation. The raw waste received at the site is pre-sorted and further sent to processing shed. The pre-sorted waste materials are being used as a raw material for windrow composting and vermin-composting. Some percentage of hotel waste and market waste is being used for bio-methanation plant. The rejects from windrow, vermin-composting and bio-methanation plant is sent to sanitary landfill site
