<strong>Revitalization</strong> <strong>of</strong> <strong>Rivers</strong> In <strong>India</strong><br />

<strong>Draft</strong> <strong>Policy</strong> Recommendation<br />

In the context <strong>of</strong> that national objective, it is useful to note that one<br />

fruit tree approximately absorbs 4.22 gm <strong>of</strong> carbon per hour. One square<br />

kilometer <strong>of</strong> tree cover has the potential <strong>of</strong> sequester<strong>in</strong>g 3,500 tonnes<br />

<strong>of</strong> CO 2<br />

per year at 400 trees per acre. So 2000 square kilometers <strong>of</strong> tree<br />

cover has the potential <strong>of</strong> absorb<strong>in</strong>g 7 million tonnes <strong>of</strong> CO 2<br />

per year.<br />

Across the 20,000 km <strong>of</strong> river length <strong>in</strong> the country, that represents a<br />

reduction <strong>of</strong> 140 million tonnes <strong>of</strong> CO 2<br />

per year. That makes a significant<br />

6% contribution to the national carbon footpr<strong>in</strong>t reduction goal via<br />

forest covers. This 6% is a conservative estimate – it is likely to be higher<br />

because we haven’t accounted for two factors: the relatively higher carbon<br />

sequester<strong>in</strong>g ability <strong>of</strong> a multipurpose tree versus a fruit tree; and the fact<br />

that we would save methane emission from annual crops like paddy by<br />

flood irrigation which has much higher global warm<strong>in</strong>g ability.<br />

Carbon farm<strong>in</strong>g 45 is agriculture’s answer to climate change. Simply<br />

put, the goal is to take excess carbon out <strong>of</strong> the atmosphere, where the<br />

element causes global warm<strong>in</strong>g, and store it <strong>in</strong> the soil, where carbon<br />

aids the growth <strong>of</strong> plants. The pr<strong>in</strong>ciple is pretty straightforward—the<br />

practice, not so much. 46 The reduction <strong>of</strong> temperature <strong>in</strong> the river<strong>in</strong>e<br />

ecosystem results <strong>in</strong> reduction <strong>in</strong> riverbank temperature relative to the<br />

river water temperature. This will lead to recharge <strong>of</strong> groundwater, and<br />

will also prevent loss <strong>of</strong> nutrients <strong>in</strong> soil <strong>in</strong>to the river.<br />

Non-destructively harvested perennial (NDHP) crops is a<br />

categorization <strong>of</strong> plants/trees that can meet human needs <strong>of</strong> oil,<br />

carbohydrates, prote<strong>in</strong>s and energy, by not destroy<strong>in</strong>g them after they<br />

yield their produce. Replac<strong>in</strong>g perennial crops that are destroyed every<br />

year after the yield<strong>in</strong>g <strong>of</strong> the produce with NDHP crops, we ensure that<br />

the soil is not tilled and therefore the organic carbon is <strong>in</strong>tact. No tillage<br />

also saves energy that is spent by mach<strong>in</strong>ery used for this purpose. 47<br />

An excerpt from the book on Carbon Farm<strong>in</strong>g, that looks at trees and<br />

tree-based farm<strong>in</strong>g as a solution to the climate change conditions that<br />

perennial crops suffer is presented <strong>in</strong> Annexure 8.<br />
