In a first of its kind effort to encourage technology-driven development at the grassroots, the science-related departments of the government got together to inform the states about indigenous technologies currently available in the country and how they can be utilised to solve everyday problems.

There is an alarming rise in sea level along the Indian coast since 2004, said Shailesh Nayak, Secretary, Ministry of Earth Sciences.

Coral reefs, the most diverse marine habitat that support half-a-million species, may start losing dominance from Indian seas starting 2030 following increase in sea temperature, says a new study.

The coastal region occupies some of the most potential aquifer systems of the country. The coastal aquifers of India ranges from that of Jurassic to Recent and is seen almost all along the coast right from Gujarat to West Bengal. Some of the aquifers especially the Tertiary to Recent ones are highly potential and are developed extensively.

Scarcity of potable water could soon be a thing of the past, at least in coastal and island states. The Low Temperature Thermal Desalination System (LTTD) converts saline seawater into potable water - that too for six to seven paise a litre!

HYDERABAD: The hard corals of Porites species, found in abundance in the blue-water lagoons of the picturesque Lakshadweep islands, are facing a threat to their existence.

Global warming caused by high CO2 levels has retarded the growth of these corals, leading to fears that they might eventually disappear.

A group of 36 coral islands is being scattered in the Arabian Sea off the western coast of India. On such islands, groundwater is the only source of fresh water for the islanders. The demand for groundwater is increasing every year due to growing population and urbanization. On the other side the peculiar hydrologic, geologic and geomorphic features restrict the availability of groundwater.

But not as much as was thought, says a study SOIL erosion worldwide is threatening our agricultural base. Our farmers are suffering. The maximum amount of soil that an area can lose without affecting its ability to sustain plant growth is the soil loss tolerance value or the T value. Previously the T value for India was set at a uniform 11.2 tonnes of soil per hectare per year. Debashis Mandal
