Cash crops are grown and sold for monetary gain and not necessarily
for sustenance. They include coffee, tea, coconut, cotton, jute,
groundnut, castor, linseed, cocoa, rubber, cassava, soybean, sweet
potato, potato, wheat, corn and teff. While some of these crops
have been improved for realizing yield potential, breeding of many
of them is still in infancy. Crops that underwent rigorous breeding
have eventually lost much of the diversity due to extensive
cultivation with a few improved varieties and the diversity in less
bred species is to be conserved. Over the past years, scholars and
policy makers have become increasingly aware of the short and
long-run impact of climatic factors on economic, food security,
social and political outcomes . Genetic diversity, natural and
induced, is much needed for the future generations to sustain food
production with more climate resilient crops. In contrast, crop
uniformity produced across the farm fields in the form of improved
varieties is genetically vulnerable to biotic and abiotic stresses.
Thus, it is essential and challenging to address the issue of
compromising between maximizing crop yield under a given set of
conditions and minimizing the risk of crop failure when conditions
change. Cash crops are grown in an array of climatic conditions.
Many of the world's poor still live in rural areas. Many are
subsistence farmers, operating very small farms using very little
agricultural inputs for achieving marketable outputs. Conserving
the diversity of these crops and addressing all issues of crop
culture through modern tools of biotechnology and genomics is a
real challenge. We believe the focus of this book is to fill an
unmet need of this and other grower communities by providing the
necessary knowledge, albeit indirectly via the academics, to manage
the risks of cash crops breeding through managing genetic
diversity.
