Week 2 PH 173
Answer to Sample Midterm Question: B) Fall in death rates, but little change in birth rates
-GEC in the News: Gov. Brown implements water rationing
-Video: Gov Brown orders mandatory water restrictions
reduce in 25% of water consumption
more than 98% of california is suffering from abnormally dry conditions
-Thomas Malthus spoke about famine.
-Population is the single largest factor in influencing food demand.
-Rising personal incomes has also influenced economic development and food demand. People that
can now afford it feel like they have to buy it. (more money= not more food but more high quality
food: meat and dairy products tend to be more expensive)
-Regions which were once healthy now have more meat-based diets and increased rates in the some of
the diseases we have here, usually stomach problems.
-Per capita consumption chart:
only for developing countries (so not the US)
impacting the people of health around the world
-trying to calculate world hunger is almost impossible. How do we quantify world hunger?
-BMR (basal metabolic rate): calories that would keep your body running at rest.
Undernourishment: <1.2
assumes were not moving
-using the 1.2 BMR: 1 billion people are undernourished ( 1/7th of the world)
-Degrees of hunger differ across nations
-High population growth regions contain a vast majority of these people
-In developing nations: 1/3rd of all children under the age of 5 are undernourished
-19,000 children die daily from malnutrioning in these less developed countries.
-Women are at a higher risk for malnutrion because of things such as pregnancy and nursing, even
higher than that of a working man. (boy children even sometimes receive more food than girl children)
-Undernourishment in 2009:
875 million people in 1969-1971 to all the way over 1 Billion people are now malnurished.
-Causes of hunger:
unequal distribution of food because of capital
increasing population by 80 million a year
people have to wait in long lines that sometimes dont have enough food
two main factors: poverty and unequal distribution
hunger is becoming endemic where there is a wide gap between food production and population
growth. (growing countries without food)
were seeing less and less farms (Irvine used to be farm land). Our land is changing bc we want
to build cities and homes.
Food riots and protests caused the rise in food prices.
Absolute poverty: earn than less than a dollar a day
we dont know if we will have food after 2025 and the distribution might be even worse
Food insecurity will increase in places like Sub-Saharn africa and Asia
even political insecurity
-Health impacts of hunger:
political unrest
leading cause of death and disease in children in developing countries: protein deficiency
this lead to greater things

inflated stomach
impacts children's physical and brain development
15-25% fewer brain cells just because of malnutrition
and if it continues it can be 50-60% fewer brain cells
they are physically smaller than they should be
most imp cause of blindness: 100-140 million children have Vitamin A deficiency which causes
blindness. It also impacts your immune system
400 million people in the world have Iodine deficiency. In the US we iodized our salt to solve
this problem. It considered the single most preventable cause of brain damage.
4-5 billion people are iron deficient
we are not eating iron rich foods, However, too much iron is bad as well.
-Prospects for reducing world hunger:
more farms, however, all the rest of suitable farming land is in south america and africa but
transportation is a problem.
Increase in fish catch: decline in predator fish and contaminants in the ocean that destruct the
habitats of these fish
aquaculture: trying to grow fish?
Sometimes we grow carniverous fish but have to be careful bc if we feed them
contaminated fish then they as well will be contaminated
REDUCE POST-HARVEST FOOD LOSSES ( MOST IMPORTANT ONE)
27% of all the available food for consumption is waisted.
-Food insecurity: when youre not sure if you have enough food for the coming days
-World fish production:
expanding aquaculture in China and in the whole world using fish farms
-Discussion question:
Marasmus: when youre protein-calorie deficienct and youre really skinny and your skin is very
loose.
-40% of the land worldwide has been degraded
-Degradation of land resources
overgrazing: most significant contributor to soil degradation
about 5% of our croplands are “seriously” degraded, meaning we really cant use them.
Weed: any unwanted plant/ aggressive plants with long roots
Soil erosion
UN has warned countries to give more attention to top soil and reduction in their harveset bc
they need the topsoil that has all the nutrients
To achieve the T value :
Conservation tillage: mulch till (everything), strip till, and no till( leave former residue
and plant right on top).
T value: tolerable amount of erosion for the top soil.
Doesnt require additional inputs of soil
Dont have to replenish topsoil
now we substitute topsoil with fertilizer
Food security act of 1985: created conservation reserve program: farmers got money if
they let their fields go dormant and restore themselves.
Natural resources conservation service: created after the dust bowl
Deforestation
