Abstract In this paper, under the background of overall food security situation in the SAARC countries, attempts
have been made to analyse the production behaviour along with the total seeds of two major food crops rice and
wheat. This will help to draw up strategies and programmes for regional cooperation in ensuring food security and
reducing hunger and malnutrition in the region. Forecasting of area, production, yield and total seed production will
not only help to solve the food security problem but also seed security in these SAARC countries in future. In
addition to descriptive statistics, the Box – Jenkins ARIMA modelling technique has been used to analyse the
information from 1961 through 2010. The forecast shows that rice and wheat production for the year 2020 would be
about 794 and 777 million tons respectively in the world. In-spite of increase in production the study reveals that the
yield of rice and wheat in world would be 4.35 t/ha and 3.4 t/ ha in 2020 but the yield of these two crops in SAARC
countries, barring one country in each, will remain far below the world projection. Thus, under the given remote
possibility of horizontal expansion, the study emphasises the need for quantum jump in the per hectare yield of these
two crops for this region. The study also advocates that good quality of seeds in good amount be made available to
the farmers, otherwise the whole food security of this part of the Globe would be under tremendous risk.

1. Introduction
World population particularly the population of
developing world is increasing at an alarming rate. To
feed this ever increasing human population always
remains a challenging task to the planners of the
individual countries and also the world bodies. The
planners should know the likely population behaviour of
the countries under changing scenario. At the same time
they should have an idea about the likely demand for food
and other commodities. Thus, forecasting production
behaviours of the major crops play vital role towards the
planners for food and nutritional security. The planners
should have idea about the likely production scenario of
the major crops. Food crops like wheat, rice play
important roles in solving food and nutritional security
problem. About two third of wheat production in the
world is used for human food and one sixth is used as
livestock feed. It is grown on 216.70 million hectares with
production of 651.40 million tonnes in the world during
year 2010. India ranks second largest producer of wheat,
next to China, accounting 11.63 percent of total wheat
production in the world. Wheat is a staple food for about
one third of population and major supplement in the
human diet containing protein, niacin and thiamine. Rice
is another major staple food and a mainstay for the rural
population and their food security. Rice is vital for the
nutrition of most of the population in Asia, as well as in
Latin America and the Caribbean and in Africa; it is
central to the food security of over half the world
population, ( C. Calpe,( FAO, Rome, Italy) 2002). Rice is
the predominant staple food in at least 33 developing
countries, providing 27 percent of dietary energy supply,
20 percent of dietary protein and 3 percent of dietary fat.
Rice can contribute nutritionally significant amounts of
thiamine, riboflavin, niacin and zinc to the diet, and also
smaller amounts of other micronutrients. Many factors
influence the nutrient content of rice (Kennedy et al., FAO,
Rome, Italy, 2002). Rice is the staple food for nearly 70%
of the Indian population. During the year 2010-11 rice
with 94.01 million tonnes of production contributed to
40.5% of the total food grain production of the country.
Wheat is the second staple food of Bangladesh ( Rabbani
et al 2009.) Rice and wheat are the principal sources of
food, calorie, and protein intake for most of the people of
Bangladesh (Karim et al. 2010). Wheat has now become
an indispensable food item of the people of Bangladesh
and it continues to fill the food gap caused by possible
