Tavy works well and does not permanently destroy the forest as long as field sizes are small and farmers leave adequate time for re-growth. However, if farmers return to the fallow fields too quickly, as they do when human population densities increase, the soils become exhausted. And if little forest is left in between fields, then there are no parent trees to provide seeds and seedlings to restore the forest. Eventually large areas of forest are transformed into wastelands, upon which nothing can grow—neither rice nor forest. On these areas, farmers pasture a few cattle and continue to burn the grasslands each year, to provide "greener grass" for the cattle.

Pollution in the environment, deforestation and lowering biodiversity are the three effects of tavy farming.

Tavy farming refers to  practice in which a farmer cuts a portion of the forest and then burns it. After turn into ashes the farmer planting rice that is irrigated by rainfall alone. This farming has a negative impact on the Madagascar's environment due to cutting of trees, burning of forest and destruction of habitat of organisms living in the forest.

In this farming, pollution occurs due to burning of wood, deforestation occurs as well as lowering the biodiversity of the area so we can conclude that pollution, deforestation and lowering biodiversity are the three effects of tavy farming.
