Over 60 farmers, agriculture scientists, and agriculture department officials took part in the one-day seminar on ‘climate change and agriculture-impacts and adaptation' held at Tamil Nadu Rice Research Institute (TRRI), Aduthurai, near Kumbakonam recently.
The seminar was organised by Tamil Nadu Agriculture University (TNAU) and South Asian Network for Development and Environmental Economics (SANDEE), Nepal.
Speakers at the seminar said that an increase in global atmospheric concentration of carbon dioxide and other green house gases (GHG) are largely responsible for climate change in the form of shift in rainfall distribution, increase in temperature, and rise in sea level. It affects agriculture by reducing soil fertility, salination, and distribution of pest population and biodiversity which in turn influence productivity, sustainability and food security.
T.Jayaraj, Director, TRRI, said erratic monsoon distribution and rising temperature would decrease the yield up to 20 per cent under irrigated conditions and over 40 per cent in rain-fed conditions which in turn drastically reduce the income level of marginal and small farmers. He spoke about the long-term adaptation measures to tackle the impact of climate change.
N.Ajjan, Director, Centre for Agricultural and Rural Development Studies (CARDS), TNAU, spoke on the effects of climate change on agricultural productivity, poverty, and food security. He explained the initiatives of the government, Indian Council for Agriculture Research (ICAR), and Tamil Nadu Agriculture University such as Clima rice project, establishment of automated weather stations, and climate research fund.
T.R.Shanmugham, Department of Agriculture Economics, TRRI, and V.Saravanakumar, principal investigator of the SANDEE, spoke, a release said here on Thursday.
