Figure 4(c): Agroforestry – an alternative to the traditional tavy method of farming

With reference to Figures 4(a), 4(b) and 4(c), outline two reasons why a change from tavy agriculture to agroforestry may be more sustainable.

Markscheme

This question requires “Resource Booklet - May 2018 SL paper 1”, available under the "your tests" tab > supplemental materials.

In agroforestry:
forests/habitats and their biodiversity are maintained / reduces deforestation;
tree/forest cover/root system reduces risk of flooding/flash floods/soil erosion;
tree canopy/plant cover reduces impact of precipitation on soils / soil erosion;
within agroforestry soil maintains organic matter / levels of fertility / trees fix nitrogen in soil / leaves from trees enrich soil;
forest provides a variety of resources e.g. medicinal plants/firewood/timber/crops / farmer can get milk and food from agroforestry / forest can provide fodder for animal;
manure from animals can be used as a fertilizer for crops/trees;
land can be used sustainably/indefinitely/over long period of time rather than for a few years;
no burning of woodland reduces amount of carbon dioxide effect on global warming/climate change / forest can absorb carbon dioxide.

Accept converse statements for tavy method.

This question requires “Resource Booklet - May 2018 SL paper 1”, available under the "your tests" tab > supplemental materials.

tavy is a method that can be considered part of the local culture/traditions;
people tend to have an aversion to change / do not trust change;
if site conditions are poor, rehabilitation can take time / if soil is poor in nutrients it can be difficult to establish agroforestry / trees take time to grow so benefits would not be seen immediately;
agroforestry cannot provide same products as traditional methods e.g. rice;
lack of education to explain the advantages of alternative methods / lack of knowledge about agroforestry / agroforestry is a more complex system to farm / tavy is easier than agroforestry /agroforestry requires more work;
lack of funds to promote agroforestry.
