The Roles of Cassava in Marginal Semi-Arid Farming in East Nusa Tenggara—Indonesia"

Abstract: Risk and uncertainty in grain crop production are common in marginal semi-arid environments, such
As East Nusa Tenggara province. Growing root and tuber crops in a mixed-cropping system is one of the strategies
Developed by smallholder farmers to substitute food grains and minimize risk. Nevertheless, root and tuber crops
are not prioritized for food production systems since food crops in Indonesia are based more on grain and wetland
rice production systems. This paper reviews cassava crops, which are widely cultivated by smallholder farmers. This
paper contributes to understanding the roles of cassava for smallholder farmers, the diversity of the cassava germ plasm, the progress made to increase cassava productivity, and the potency of cassava crops to improve farmers’ incomes. This paper highlights that, in the low and erratic rainfall of dominant semi-arid regions, the development of cassava is pivotal to secure the harvest of food crops or food availability and income generation for marginal farmers.
