Meeting the world's food security challenge will require a
multi-national, collaborative effort to integrate the best research
from science, engineering and socioeconomics so that technological
advances can bring benefits where they are most needed. The present
book covers the effect of major environmental problems on crop
production and how to cope with these issues for sustainable
agriculture and improvements of crops. The world's population is
predicted to hit 9.6 Billion by 2050, up from today's total of
nearly 7.3 Billion, and with it food demand is predicted to
increase substantially. The post-war 'second agricultural
revolution' in developed countries, and the 'green revolution' in
developing nations in the mid- 1960s converted agricultural
practices and elevated crop yields spectacularly, but the outcome
is levelling off and will not meet projected demand.
Simultaneously, crop production is affected by many other factors,
including industrial pollution, overuse of fertilizers and
insecticides, heavy metal and radiation stresses etc. It has been
noted that many pests are becoming resistant to insecticides.
Estimates vary, but around 25% of crops can be lost to pests and
diseases. Climate change associated with agriculture is also a
global issue. Agriculture is a significant contributor to
greenhouse gases and is estimated to account for 10-12% of total
greenhouse gas (GHG) emissions. Many of the issues highlighted are
global problems and are addressed thoroug hly in this work.
