For a typical Indian farmer, using dung as cooking fuel in the form of biogas is a very costly techbnology. He would need about 40 kg dung every day for producing the necessary amount of gas. Because of higher standard of living of people in the cities, the ritual use of dung cakes and also their price has increased. The dung cakes made from 40 kg dung can be sold for <u>US$1 </u>. Spending a dollar every day for cooking the meals is absurd, because the food that the family eats, costs less than that. We are advocating that villagers use biogas plants of our design. 10 kg green leaves yield the same amount of biogas as 40 kg cowdung, and it takes only three days for the leaves to do this, while dung has to remain in the biogas plant for about 40 days. Dung can be used as an agricultural input. I have been advocating a type of agriculture which uses no fertilizers, because all the minerals required by plants are available in the natural soil. Just yesterday I saw on the t.v. an interview of a proponent of this type of farming. He claimed that about four million farmers in India followed his advice. All he advocates is to apply to the farmland 25 kg cowdung per ha, once a month. This keeps the number of micro-organisms in soil high, and it is the microbes which in turn make the soil minerals available to the plants. In my lectures, I advocate the use of 125kg green leaves per ha, once every two months.</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>Yours</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>A.D.Karve</div></blockquote><div><br></div></div><div class="gmail_extra"><span class=""><br clear="all"><div><div data-smartmail="gmail_signature">***<br>Dr. A.D.

Taken all the emissions from the production to consumption of foods - including those due to cutting forests, open burning of grass and leaves, forest fires - and valued in 20-year GWP terms, the contribution to atmospheric concentrations is much greater than that, say, from power generation. <br><br>Go read Nadine Unger. <br><br>Or Nick Stern, who I believe has gone veg.
