There was a time when India had acute shortage of sugar. Then the government increased the procurement price of sugarcane and continues to increase the procurement price periodically. This has led to India becoming not only self sufficiet but also surplus in sugar.Not only this, sugarcane is one of the only 2 or 3 crops in which India’s yield is higher than world and Asian average yield.
If countries which are deficit in cereals increase procurement prices substantially,the farmers will find ways to increase the yield and production. These countries should also impose import duties on cereals to such an extent that the local produce becomes cheaper. The deficit in food grains can easily be wiped out in most of the deficit countries.
The question will arise as to how poor people who are malnourished for want of money to buy food gains shall buy at higher prices. The people do not have buying power because they do not have enough work. The govenments there should undertake massive works like digging lakes, canals, wells,laying roads, railway lines, power transmitters and lines solar power stations, hydro-electric power stations etc. Most of the west and east African countries receive over 1000 mm rainfall every year and hence increasing food grain production may not be a big problem at all.
