FOOD AND
AGRICULTURE
AND
ENVIRONMENT
WORLD FOOD SUPPLY AND THE
ENVIRONMENT
Modern food problem is associated
with two processes:
The great increase in human
population  outstrips local food
production in many areas.
An inadequate food distribution
system for these growing
population
WORLD FOOD SUPPLY AND THE
ENVIRONMENT
Increase in world food production in
the past have been accomplished in
two ways:
Increase the area in food
production
Increasing the production per unit
area
LAND, PEOPLE, AND AGRICULTURE:
 11% of the total land area of the world is in
agriculture
 In the future, when the human population doubles,
the production of agriculture must double, just to
meet the present level of per capita food
consumption. The associated problem is:
◦ More land will be required for the housing of the
additional population.
 we need to increase productivity per unit area
 Food production depends on the environment e.g.,
drought, lack of crucial resources.
AN ECOLOGICAL PERSPECTIVE ON
AGRICULTURE:
 Biome: large naturally occurring community of
flora and fauna occupying a major habitat
 Agro-ecosystems : Agriculture can be viewed as
human-developed biome which can be termed as
agro-ecosystems.
SOIL AND AGRICULTURE:
 Agricultures depend heavily on soil quality but can
lead to a decline in that quality:
 Amount of organic matter declines
 Traditionally, farmers combat the decline in the soil
fertility by using:
 Organic fertilizer such as animal manure
 Chemical or Artificial fertilizers.
SUPPLY:
 
 Green Revolution: Development of new types of
crops with higher yields, better resistant to
diseases, or better ability to grow under poor
condition.
 Improved Irrigation: improve yield and reduce
overall water use.
 Increasing the amount of agricultural land:
EFFECTS OF AGRICULTURE ON
ENVIRONMENT
 ON-SITE OR PRIMARY
EFFECTS:
◦ Includes erosion, loss of soils, and
increase in sedimentation
downstream in local rivers.
 OFF-SITE OR SECONDARY
EFFECTS
◦ Global effects include climatic
changes as well as potentially
extensive changes in global
MAJOR ENVIRONMENTAL PROBLEMS
THAT RESULT FROM AGRICULTURE
INCLUDE:
 Deforestation
 Desertification
 Soil erosion
 Degradation of water resources
 Salinization
 Accumulation of toxic metals
 Accumulation of toxic organic compounds
 Soil, air, and water pollution

Food and Agriculture and Environment Lec 11

  • 2. WORLD FOOD SUPPLY AND THE ENVIRONMENT Modern food problem is associated with two processes: The great increase in human population  outstrips local food production in many areas. An inadequate food distribution system for these growing population
  • 3. WORLD FOOD SUPPLY AND THE ENVIRONMENT Increase in world food production in the past have been accomplished in two ways: Increase the area in food production Increasing the production per unit area
  • 4. LAND, PEOPLE, AND AGRICULTURE:  11% of the total land area of the world is in agriculture  In the future, when the human population doubles, the production of agriculture must double, just to meet the present level of per capita food consumption. The associated problem is: ◦ More land will be required for the housing of the additional population.  we need to increase productivity per unit area  Food production depends on the environment e.g., drought, lack of crucial resources.
  • 5. AN ECOLOGICAL PERSPECTIVE ON AGRICULTURE:  Biome: large naturally occurring community of flora and fauna occupying a major habitat  Agro-ecosystems : Agriculture can be viewed as human-developed biome which can be termed as agro-ecosystems.
  • 6. SOIL AND AGRICULTURE:  Agricultures depend heavily on soil quality but can lead to a decline in that quality:  Amount of organic matter declines  Traditionally, farmers combat the decline in the soil fertility by using:  Organic fertilizer such as animal manure  Chemical or Artificial fertilizers.
  • 7. SUPPLY:    Green Revolution: Development of new types of crops with higher yields, better resistant to diseases, or better ability to grow under poor condition.  Improved Irrigation: improve yield and reduce overall water use.  Increasing the amount of agricultural land:
  • 8. EFFECTS OF AGRICULTURE ON ENVIRONMENT  ON-SITE OR PRIMARY EFFECTS: ◦ Includes erosion, loss of soils, and increase in sedimentation downstream in local rivers.  OFF-SITE OR SECONDARY EFFECTS ◦ Global effects include climatic changes as well as potentially extensive changes in global
  • 9. MAJOR ENVIRONMENTAL PROBLEMS THAT RESULT FROM AGRICULTURE INCLUDE:  Deforestation  Desertification  Soil erosion  Degradation of water resources  Salinization  Accumulation of toxic metals  Accumulation of toxic organic compounds  Soil, air, and water pollution
