National Conference on <strong>Science</strong> of Climate Change and <strong>Earth</strong>’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’<br />
<strong>12</strong>-<strong>14</strong> <strong>September</strong>, <strong>2011</strong>, <strong>Lucknow</strong><br />
Increase in agricultural production through organic process would satisfy<br />
parameters of sustainability, social acceptance and economic viability. All this is<br />
possible with direct assistance of animal population.<br />
It is beyond doubt that agriculture is not an industry. Industry is for the rich while<br />
agriculture is for the poor. Vice-versa is not true. Agriculture provides food for all.<br />
Animal’s solid waste is an asset for the mankind. They serve the mankind<br />
sincerely throughout their life. They do not affect the balance of nature – air, water and<br />
food. They have everything man needs – fertilizer, pesticide and energy.<br />
Human beings ‘only talk’ of ‘green economics’ while animals live and maintain<br />
‘green economy’ by themselves. Humans need to learn from these animals. The active<br />
support of these animals should be utilized (not exploited).<br />
The treatment of animal waste will take place in cottage industry model at family<br />
level in the villages. The village economy and hence the national economy will undergo<br />
drastic change.<br />
The potential of this sector in <strong>India</strong> is worth about $ one trillion per year.<br />

Variation in the preservation of biotic forms in chronological order has been<br />
studied in ecological perspective in two 2.5 and 5m deep sediment cores deposited since<br />
~3440 yrs BP and ~3630 yrs BP, respectively in the central part of Pichavaram<br />
mangrove wetland, Cauvery river delta. The preservation of organic matter is mainly in<br />
clay to silty clay sediments which constitutes remains of fresh water algal matter, fungal<br />
remains, dinoflagellate cysts, thecamoebians, foraminifera and loricated tintinid<br />
remains. The percentages of these vary in the sediment cores indicating 4 different<br />
ecological zones. The Phase I (~3630-3190 yrs BP) shows a stabilized estuarine<br />
ecosystem with a warm and humid climate coupled with moderate monsoon condition.<br />
Phase II (~3190-2750 yrs BP) reveals a high fluvial energy condition suggesting<br />
climatic amelioration from warm and humid to dry and arid. Phase III (~2750-760 yrs<br />
BP) shows a dry and arid climate coupled with weakened monsoon and Phase IV (since<br />
~760 yrs BP) shows a stratified estuarine condition with low fluvial energy favoring the<br />
growth of both fresh water and marine forms. Overall palynological and<br />
