South India Wetlands Review 2017: Wetlands Critical in Changing Climate

KERALA WETLANDS REVIEW 2017

State wetlands face multiple threats In March 2017, a book titled “Biodiversity Richness of Kerala” revealed that riverine ecosystem of Kerala were subjected to human pressures in form of deforestation, land use change, construction of dams, roads, encroachments and mining affecting water holding capacity of the catchments and leading to drying up the rivers and wetlands. Kerala constituted only 1.18 per cent of India’s geographical area but it accommodated 25.69 per cent of the flowering plants in the country. In 2004, Kerala had around 328,402 hectare of wetlands which over the years had fallen to 160,590 hectare dramatic 49 per cent decrease. http://www.business-standard.com/article/news-ians/kerala-wetlands-face-multiple-threats-says-book-117030200590_1.html (Business Standard, 2 March 2017)

Mining posing threat to mangrove forests In Feb. 2017, the district environment committee of the Kerala Sastra Sahithya Parishad alleged that the mineral sand-mining activity carried out by the public-sector Indian Rare Earths along Vellanathurutu in Alapad panchayat was causing widespread damage to the naturally growing mangrove forests in the area. Calling for immediate ban on mining activity the committee complained that a destructive mechanical process was being applied in the area instead of applying the more eco-friendly beach washing method of mining.  According to committee the activity had already destroyed over 2 ha of mangrove forests at estuary where the Pallikkal River met the sea. At least 12 mangrove species, some of them threatened or endangered, were growing in the region. http://www.thehindu.com/todays-paper/tp-national/tp-kerala/Mineral-sand-mining-posing-threat-to-mangrove-forests/article17281729.ece (The Hindu, 10 Feb. 2017)

Karnataka Wetlands Review 2017: Bellandur Lake Remains On Fire

Wetlands For A Sustainable Urban Future : Text from Face Book post by Vishwanath Srikantaiah on occasion of World Wetlands Day 2018. 

Much grief, energy and monies can be saved if we imagine our ‘tanks’ as wetlands rather than water bodies in the city of Bengaluru.

World wetlands day is celebrated on the 2nd of February every year. For this year 2018 the theme is “Wetlands for a sustainable urban future”.

A simple definition for a wetland is that it is an area that tends to be saturated with water either permanently or seasonally and harbours a distinct type set of plants. Wetlands behave differently from a water body like a lake and need to be managed, if at all, completely differently.

Wetlands harbour bio-diversity much more than only water, have the ability to absorb pollutants and nutrients better, can manage floods, recharge groundwater, moderate temperature and area huge asset for a city.

In the city of Bengaluru itself the Karnataka State Lake Conservation and Development Authority (KLCDA) has sent a proposal to the central government that 176 tanks within the city be declared as wetlands. This would potentially protect these tanks better from encroachment and solid waste dumping as well as the construction of roads within.

The polluted stretches of the Vrishabhavati and the Dakshina Pinakini could also be brought under wetlands protection.

Wetlands, in combination with waste-water treatment plants, are a good way of reviving the tanks in the city. The example of Jakkur and Rachenahalli are possible starting points for an integrated approach to manage water in the city with wetlands playing an important role. Here waste-water treated to secondary standards are then allowed in to the wetlands which remove nitrates and reduce Total Suspended Solids, thus allowing for it to fill the water body. In turn , the lakes allow for fishing and recharge the surrounding aquifers.

Wetlands provide for a range of services including livelihoods for the poorer sections of society. Even now a range of fodder collectors pick up grass and alligator weed ( called Hongonney in Kannada ) for feeding their cattle almost all across the city.

Remedied waste-water from the city can be further treated in the wetlands and used for agricultural purpose. The proposal and project to transfer treated waste-water to the districts of Kolar and Chikballapur can also benefit substantially if wetlands are integrated in to the design at the first receiving tanks. This would also enhance flora and faunal biodiversity in the tanks of these drought prone rural districts at the same time benefiting agriculture there.

Integrating wetlands into the master plan and the urban fabric of cities is the need of the hour and that would be water wisdom.

West India Wetlands Review 2017: No Protection Here

GUJARAT WETLANDS DEVELOPMENTS 2017

Gosabara wetland declared IBA In March 2017 during a two days workshop, The Bombay Natural History Society (BNHS) declared 96 sq km coastal wetland area of Gosabara-Mokarsagar in Porbandar, as Important Bird Area (IBA) site. There are around 544 IBAs in India and 18 in Gujarat. As per experts though IBA does not have any legal status, it helps environmentalists to raise alarm if the site faces any threats and press for its conservation. In 2001, Salim Ali Centre for Ornithology (SACON) conducted a country-wide survey for important ‘Inland Wetlands of India’ and Gosabara-Mokarsagar wetland was one the 50 important wetlands of the country.  https://timesofindia.indiatimes.com/city/rajkot/gosabara-wetland-now-a-bnhs-iba-site/articleshow/57453811.cms  (The Times of India, 4 March 2017)

Maharashtra Wetlands Review 2017: Destruction Despite Legal Intervention

Throughout 2017, civil society groups have been working hard to protect the wetlands in mangrove and coastal area in Maharashtra. Bombay High Court has also passed several orders in this regard. State Government has taken some steps in the interest of wetlands. However despite all these, the wetlands in Maharashtra stand at the receiving end of encroachments, pollution and waste dumping.
