FOOD, THE WEAK LINK“WE ARE ENTERING A NEW ERA OF RAISING FOOD PRICES AND SPREADING HUNGER” –LESTER BROWN
FOOD EQUATION:
Demand Population growth Rising affluence conversion of food into
fuel
Supply Soil Erosion Growing water Shortages Grain yields plateauing Rising temperatures
PRODUCTION HAS ITS LIMITS BUT DEMAND KEEPS ON

FOOD SECURITY
Large stocks of grains cushioned world crop shortfalls.

RISING FOOD PRICES, STRAINED BUDGETS AND HUNGER
Rising demand is raising food prices, for consumers who spend more than 50% of their income on food this
represents a serious problem, forcing them to eat less.
The increasing demand for food is rising food prices, making the poor not being able to keep up with them. Now many households that ate at least one meal a day have foodless days as a weekly routine.
RISING FOOD PRICES, STRAINED BUDGETS AND HUNGER
Despite the efforts to eradicate hunger, relentless population growth is making it more difficult and is putting excessive pressure on land and water resources making it difficult for farmers to keep pace. Most of the nearly 1 billion people who are chronically hungry live in the Indian sub-continent and the sub-Saharan Africa.
RISING FOOD PRICES, STRAINED BUDGETS AND HUNGER
These graphs show how population is growing even faster in developing countries, precisely countries that have hunger problems have the highest population growth rates making this problem persistent over time.

MOVING UP THE FOOD CHAIN
Worldwide roughly 35% of the 2.3 bi l l ion ton annual grain harvest is used for feed. In contrast, nearly al l of the soybean harvest ends up as feed.
People with the longest l i fe expectancy are not those who l ive very low or very high on the food chain but those who occupy an intermediate positi on.

WATER AND FOOD SCARCITY40% of the world grain harvest is grown on irrigated land, and 40% of world irr igated area is dependent on underground water.
Water tables are fal l ing, irr igati on wells are going dry.
If the pumping surpasses the sustainable yield of the aquifer, aquifers are depleted.

WHAT CAN WE DO?
Reduce excessive meat consumpti on.
By eati ng less meat we can save: Water Land Grains Fuel.

By eati ng less meat we can reduce methane emissions and ease global warming
WHAT CAN WE DO?Reverse biofuels policies
Do not support the use of biofuels, do not buy grain-based fuel.
