Population  Growth  and Food Supplies

The  impact of population growth on food supply and nutrition will be greatest in countries already challenged by poverty and in adequate nutrition. Even though food supplies have increased in the past 30 years, more than 800 million people do not have enough food to meet their basic nutritional needs.

The current  world  population is 6.8 billion is  projected  to  grow  to 9.5  billion  by  2050 up  from  5.3 billion in  1990. This is an increase of 30 % in 20  years. India  and China expected to have equal population in 2028 .

India is home to 3 % of the world’s land mass with 17 % of its people, second only to China with 9 % of land mass with 20 % of the world's people.

Crop Yields  And Food Security. (All bracketed values are stand for India).

According to the United Nations  Food and Agriculture Organization (FAO), 30 % to 40%  of worldwide food production comes from an estimated 200 millions of irrigated lands –only one sixth of the world’s farmland. Irrigated farms have 50% -200% higher yields for most crops. Water clearly plays a critical role in food production. And the  resources that are central to world food security are as follows.

 

Ever increasing population  and food  nutritional needs .

  Finite  natural  resources;
  Degradation of natural resources.
  Global warming and subsequent  climatic variability .
  Production of  Bio fuel /  Ethonal  for transport fuel .
  Arable land decreasing to 0.086 ha per capita.
  Heavy spells of rain  and high temperatures will cause  flood and draught .
  World produces about  2.3 trillion tons of cereals (2300 millions tons ).
  This is ten  times what India produces. Only U.S and China produces more than  one sixth  380 millions tonnes.
  India’s gross cultivated area is about 190 million hectare and world over total cultivated area is 700 million hectare. 
  For the world as a whole, agricultural production will slow from average annual growth rate of 2.3 % during 1970 -1990 period to 1.8 % during the 1990 -2010 period.
  India has two roughly equal harvests a year karif and rabi.
  China takes three crops in its fertile valleys.
  All other nations due to climatic conditions produces once only .
  Normally world food grain stock is about 25 %  but in 2007 it fell down to 20% and now to 15%.

Israel alone can not be a model for Indian agriculture. A total area of  20,329 sq km (3287590 squire km and a growth rate of 1.6 %. Slightly larger than Massachusetts or half the size Haryana state of India .

Israel  has a total cultivated land of 400,000 hectares (16100,000  hectare) out or which  250, 000 hectares  (53000,000  hectares) are irrigated. A Population of 7.233 million   (1200  million) 0.6 %.of India .While Indian population increase is five times of Israel every year. Most of Israel farm size is more than 13 hectare and kibutz are more 200 hectares. Only 5% [60 % ] of population is in agriculture. 

How did China manage to outstrip India in agriculture when the two countries were more or less on a par  far as arable land (161 million hectares vs 130 million hectares ) irrigated land ( 55.8 million hectare  vs  54.5 million hectares ) and farm size  ( 1.4 hectare vs 0.4 hectare ) and farm  mechanization  (15.7 tractors vs 7 tractors per 1000  hectares.

India has 161 million hectares and world over total cultivated area is 700 million hectares. For the world as a whole, agricultural production will slow from average annual growth rate of 2.3 % during 1970 -1990 period to 1.8 % during the  period 1990-2010. Present goal of India is 4 % growth in agriculture and 8 % in horticulture and animal husbandry.

Current concerns in India for food security are as follows
Efficient Crop Rotation & Double Crops with Rain Water
Re-Cycling Organic Waste
Organic Farming up to the Possible Extent
Sustainable Agro forest
Dual Water System
Growing Local Food
Keeping the Ground Fertile & Keeping Away From Plastics
