The document discusses the links between population growth and food production. It notes that population growth has increased demand for food, resulting in more farmland and water usage. Food production depends on limited resources like cropland and water that are under strain from rising populations. The document recommends strategies like improving crop yields, using resources more efficiently, shifting diets to require fewer agricultural resources, and reducing food waste to help address global food security challenges in the face of population growth.

1. Large Population
& Less Agriculture

2. Introduction
• Increasing numbers of people often drive up demand for food, which
results in additional use of arable land and water.
• Population and economic growth will result in a doubling of demand
for food globally.
• The population growth led to conversion of farm land to commercial
land and housing areas

4. Links between Population and Food
Production
• Most of the countries with the highest numbers of people facing food
insecurity also have rapid population growth.
• Food production depends on croplands and water supply, which are
under strain as human populations increase.
• Pressure on limited land resources, due to population growth, can
mean expansion of cropland.
• This lead to destruction of vital forest resources or overexploitation of
arable land.

5. According to FAO
• Food aid without simultaneous developments in local agriculture
sectors does not provide a sustainable solution to food insecurity to
population.
• Globally, the world is becoming more urban residents with high
population density, without land to farm, their food security is
dependent on their income and ability to purchase food products.
“Increased production of food alone will not solve the world’s
food security problem”

6. Factors to bring a change

mentioned by their usage in
sustainable ways can bring a global
change.

7. Advances in Agriculture and Population
 Hunters and Gatherers - during stone age
 Farming- About 10,000years ago
 The Industrial Revolution- during 1700s
 Green revolution
 The Future

8. Green Revolution
• Improving crops by selecting for traits that promote productivity;
recently, genetically engineered crops have been introduced.
• Increasing the use of artificial fertilizers and chemical pesticides.
• Agricultural machinery: plowing, tilling, fertilizing, picking, and
transporting are all done by machines.
• Increasing access to water. Many farming regions depend
on groundwater, which is not a renewable resource. Currently about
70% of the world’s fresh water is used for agriculture.

9. Five steps to Feed the World
1) Freeze Agriculture’s Footprint
2) Grow More on Farms We’ve Got
3) Use Resources More Efficiently
4) Shift Diets
5) Reduce Waste

10. 1.Freeze Agriculture’s Footprint
 The Forests and grasslands are converted to
farmlands to increase production.
 The loss of whole ecosystems around the globe,
forests continue to be cleared at alarming rates.
 Most of the land cleared for agriculture in the
tropics not contribute food security but instead
used to produce cattle, soybeans for livestock,
timber, and palm oil.
 Avoiding further deforestation must be a top
priority.

11. 2.Grow more on farms we have got
• The green revolution increased yields in Asia and globally
• Using better crop varieties and more fertilizer, irrigation, and
machines—but with major environmental costs.
• The world can now turn its attention to increasing yields on less
productive farmlands production levels and those possible with
improved farming practices.
• Using high-tech, precision farming systems, as well as approaches
borrowed from organic farming
• we could boost yields in these places several times over.

12. 3.Use Resources More Efficiently
• The green revolution relied on the intensive—and
unsustainable—use of water and fossil-fuel-based
chemicals.
• Commercial farming started to make innovative
ways to target the application of fertilizers and
pesticides by using computerized tractors equipped
with advanced sensors and GPS.
• Growers apply customized blends of fertilizer
tailored to their exact soil conditions, which helps
minimize the runoff of chemicals into nearby
waterways.

Sustainable Agriculture
Application of tailored fertilizers and
irrigation methods.

14. Organic Farming
• Organic farming can also greatly reduce the use
of water and chemicals by incorporating cover
crops, mulches, and compost to improve soil
quality, conserve water, and build up nutrients.
• Many farmers have also gotten smarter about
water, replacing inefficient irrigation systems with
subsurface drip irrigation.
• Advances in both conventional and organic
farming can give us more “crop per drop” from our
water and nutrients.

15. 4.Shift Diets
• It would be far easier to feed people if more of the crops we grew ended up in
human stomachs.
• Today only 55 percent of the world’s crop calories feed people directly; the rest are
fed to livestock (about 36 percent) or turned into biofuels and industrial products
(roughly 9 percent).
• Finding more efficient ways to grow meat and shifting to less meat-intensive diets
free up substantial amounts of food across the world.
• The use of food crops for biofuels could also go a long way toward enhancing food
availability.

17. 5. Reduce Waste
• An estimated 25 percent of the world’s food calories and up to 50 percent of total
food weight are wasted before they can be consumed.
• Waste occurs in homes, restaurants, or supermarkets.
• In poor countries food is lost between the farmer and market, due to unreliable
storage and transportation.
• Consumers can reduce waste by serving smaller portions, eating leftovers, and
encouraging cafeterias, restaurants, and supermarkets to develop waste-reducing
measures.
• Of all of the options for boosting food availability, tackling waste would be one of the
most effective.
