Global warming: A cause for concern

PANAJI: Environmentalists have suggested planting of more trees, use of vermiculture to reduce waste at source and tapping of renewable energy to


offset carbon footprints and counter the effects of global warming. "If India's temperature rises by 2 degrees celsius, there will be millions of environmental refugees," Emmanuel D'Silva, environmental scientist, said, quoting studies in this respect. "And it is important to accept that we are part of the problem" instead of thinking it is happening due to somebody else's fault".
Speaking on the theme "Taking responsibility for global warming" at Go! Green Goa - a workshop on ecological resurgence organized by Mozaic Design, an architecture firm, in association with other NGOs in the city, D'Silva said that India being one of world's top emitters of carbon dioxide, it was important to look at solutions. "About 94% of emissions are caused by the use of firewood," he said.
D'Silva called for planting of trees, especially neem and huge banyan trees, vermiculture to treat waste at source, as transportation of garbage in trucks costs crores of rupees and not only generated more emissions but also resulted in the burning of fossil fuel. "Organic waste in cities and urban areas should be recycled," he said. Citing some success stories in the use of biofuels made from pongamia trees which generated employment for the poor, he urged people to switch from incandescent bulbs to the energy-saving fluorescent ones.
N P S Varde, director and member secretary of Goa Energy Development Agency, said, "Our environmental problems are caused due to the use of energy, pollution in kitchens from chullahs, cutting of forests for timber and smoke emissions from transport vehicles."
Sharing his expertize on renewable energy solutions and advocating its use to reduce dependence on electricity, he said that alternate energy cannot replace the conventional type but can complement its use.
Stating that proponents of alternate energy solutions are working against the tide, he said, "There are points about renewable energy that are not appreciated." Use of solar energy can help reduce the dependence on electricity and carbon emissions, he added. About electricity, he explained that though citizens pay one rupee per unit for electricity, it actually costs Rs 7 but the subsidies are hidden and unknown to citizens.
Darryl Pereira explained how traditional and modern methods can be integrated in farming, while Lucano and Isa Alvares spoke about growing food at home. Clea Chandmal and Bruna Fogaca elaborated on the principle of permaculture in agriculture. Miguel Braganza stressed on organic food marketing while Yogita Mehra, a TERI researcher also spoke. Aaron Pereira, a representative of Indian Youth Climate Network, spoke about climate change, which was followed by the screening of a movie AD 2040 - the greenhouse effect.
