The growing economy along with emerging industries generates hazardous waste which if not managed can pose to be a serious health hazard. Various strategies put forward by the Ministry of Environment and Forests in terms of regulatory and institutional framework, technical guidelines, identification, treatment and disposal to manage such waste are in place, but they require effective implementations.

With the increase in demand, withdrawal of groundwater has increased manifold over past few decades resulting in the long-term decline in groundwater levels. A higher rate of withdrawal over several years with heavy pumping coupled with rapid urbanisation has reduced the natural recharge of aquifers. Rainwater harvesting and guiding the non committed surface runoff to a depleted aquifer are ideal solutions for mitigating the problem.

Of the various macro-engineering schemes proposed to mitigate global warming, ocean iron fertilisation is one that could be started at short notice on relevant scales. It is based on the reasoning that adding trace amounts of iron to iron-limited phytoplankton of the Southern Ocean will lead to blooms, mass sinking of organic matter and ultimately sequestration of significant amounts of atmospheric carbon dioxide in the deep sea and sediments.

Bioplastic is an important and exciting new field in biotechnology which promises to help in saving the environment and slow down the depletion of non renewable resources. Bioplastics may be derived from biomass sources, such as vegetable fats and oils, corn starch, pea starch etc., rather than fossil fuel plastics which are derived from petroleum. However not all bioplastics are designed to biodegrade.

In a world which is increasingly becoming spatially aware geography and geographic information system (GIS) need realignment to enable geographers to fit in.

India is steadily venturing into renewable energy resources like wind and solar. With such unpredictable energy sources feeding the grid, it is necessary to have a grid that is highly adaptive in terms of supply and demand. A good electric supply is one of the key infrastructure requirements to support overall development, hence, the opportunities for building smart grids in India are immense.

Anoxia occurs when dissolved oxygen concentration in the water is zero, a level where most organisms cannot survive. The western Indian continental shelf which underlies the Arabian Sea becomes anoxic under certain conditions. This article delves into the phenomenon and the impact it has on the region.

Sea level change research has become crucial to the debate of climate change. This article attempts to identify factors that have been linked to sea level changes across the world, the change measurements and the possible consequences with special reference to the Indian Ocean.

In India, there is an urgent need to enhance the earning capacity of the people living along the coastal areas. Sea farming through large scale seaweed cultivation is being considered as an alternate and additional means of livelihood.

Climate change can have a strong impact on fisheries with far-reaching consequences for food and livelihood security of a sizeable section of the population in India.
