System of Rice Intensification – Drawdown Strategy #53

The abbreviation SRI can stand for a number of things: Socially Responsible Investing[i], Scholastic Reading Inventory[ii], even the Stanford Research Institute[iii]. In climate and agricultural circles, however, SRI stands for System of Rice Intensification[iv]: a revolutionary method of growing rice developed by a French Jesuit in Madagascar in the 1980s. From humble beginnings in the…

Improved Rice Cultivation – Drawdown Strategy #24

Improved Rice Cultivation   20% of all calories[i] consumed worldwide comes from the humble rice grain, feeding approximately 3 billion people each year. Up to 20%[ii] of all methane (CH4) emissions each year also comes from rice—representing 10%[iii] of the agricultural sector’s yearly greenhouse gas (GHG) emissions (1.5%[iv] of the global total). While methane does…

District Heating – Drawdown Strategy #27

At first glance, district heating and cooling (DHC) sounds like the most modern of technologies. However, these networks of pipes that convey heated or cooled water into and between buildings have been around as far back as ancient Rome[i], where they were used to heat thermal baths, temples, even greenhouses.   DHC has come a…

Drawdown Strategy #23 – Farmland Restoration

“The default mode of all land is regeneration.”[i] Land is resilient: when degraded, it rebounds, regaining its ability to sustain life. Over the last century, however, land degradation—defined by the United Nations Food and Agricultural Organization[ii] as “any diminishment of biodiversity and ecosystem functioning that negatively impacts the provisioning of ecosystem services and ultimately impedes…

Drawdown Strategy #20 – Clean Cookstoves

Food nourishes human life, but cooking can be deadly. That’s the stark reality for 3 billion people[i]—40% of the world’s population—because of their stoves. In much of the developing world, households still use rudimentary stoves powered by charcoal, coal, and manure, and these fuels release deadly particulate matter. Household air pollution, in fact, is the…

Drawdown Strategy #20 – Nuclear Energy

HBO’s critically-acclaimed miniseries Chernobyl has recently brought nuclear energy back into the limelight, to mixed[i] reviews[ii]. Although the show’s creator Craig Mazin stressed in a tweet[iii] that “the lesson of Chernobyl isn’t that modern nuclear power is dangerous,” some viewers[iv] have taken away that message regardless. There’s no question, however, that nuclear power has a…

Drawdown Strategy #19 – Managed Grazing

We have already briefly encountered managed grazing, #19[i] on the Drawdown organization’s top 100 solutions to reverse climate change[ii], in our post on regenerative agriculture[iii]. Managed grazing is one of the four core practices of regenerative agriculture, because it can improve soil health, increase biodiversity and water retention, and sequester atmospheric carbon. In fact, Drawdown…

Drawdown Strategy #18 – Geothermal Energy

Humans have harnessed the heat within the Earth for millennia, perhaps most notably in the ancient Roman baths that served as centers of city life. Far more recently, we have begun to draw upon this geothermal energy—from the Greek roots geo (‘Earth’) and thermos (‘heat’)—as a renewable source of power. The planet contains an astronomical…
