Here it was observed that manioc swiddens were customarily cleared and burned very incompletely, the stem-cuttings being planted among tangled and rotting debris (Figs. 1 and 8), whereas maize swiddens were cleared and burned more thoroughly and the seeds planted in open ground. Analysis of soil samples from manioc and maize plots revealed that, whereas in the latter organic carbon showed an expected decrease following clearance and burning, in the former it actually increased.

The Urarina, an Indian people of the Amazon in northern Peru have an interesting agricultural system which can become either slash and burn or slash/mulch. They slash the understory brush, plant plantains in the cut brush, and then fell trees on the cut brush and plantains. Sometimes they burn the slashed brush after it dries, but sometimes, if there is too much rain or if there is insufficient vegetation for a good burn, they do not burn, but simply let the slashed vegetation decompose. They may also plant maize, cassava, peanuts, and squash, sugar cane, taro, and sweet potatoes in their plots. Plots are generally abandoned after 2-3 harvests. Their system also effectively protects the soil from erosion. Kramer noted that the Urarina consider the system less difficult and labor intensive than the conventional slash and burn system. slash and burn, slash/mulch, Amazon, Peru

describes how committed scientists saved the cassava root crop in Africa
In much of the developing world, the cassava is a staple. In Africa alone, the cassava helps feed more than 200 million
people. The essay recounts how famine in parts of Africa was prevented with a successful campaign to defeat insects that
