Feeding 8 Billion People Well
Transcript of Feeding 8 Billion People Well
Raising Water Productivity
Raising irrigation efficiency is central to raising overall water productivity
Producing Protein More Efficiently
Increasing protein in diets today
Localization of Agriculture
Oil prices are rising, resulting in increased food prices.
Strategic Reductions in Demand
Actions on Many Fronts
Food security is something in which we all have a stake—and a responsibility

Feeding 8 Billion People Well
1,000 t of Water = 1 t of Grain
Seventy percent of world water use is devoted to irrigation
Due to evaporation and other natural factors usage never reaches 100 percent.
In India, Mexico, Pakistan, the Philippines and Thailand between 25 to 40 percent is used
The switch from flood or furrow to low-pressure systems reduces water use by 30 percent
The switch to drip irrigation typically cuts usage in half
Institutional shifts can also help in the reduction of over usage
Case Study: China
China plans on raising water efficiency from 43 percent in 2003 to 55 percent in 2030
Raising water price, incentives for adopting more irrigation-efficient technologies, and developing the local institutions to manage water distribution.
At Home Solutions
A reduction in the consumption of meat, milk, and eggs could easily cut grain use per person by 100 kilograms.
More water-efficient household appliances
Odorless dry-compost toilets that use no water at all.
With the increase of income and health concerns the demands of proteins has risen
Aquaculture is the fastest growing source of animal protein since 1990
The four crop producing provinces in China
In Iowa on average conventional produce has traveled 1,500 miles from farm to plate
In Canada 58 imported foods traveled more than 2,800 miles
The number of farms in the United States increased by 4% for roughly 2.2 million farms
Most are operated by women, with an increase of nearly 30% of women farmers.
Organic farms increased from 12,000 to 18,200.
Many cities and small towns have community gardens that are used by citizens that would otherwise not have access to them
Farmers markets have nearly tripled in number from 1994-2009
Many now take food stamps, allowing low-income consumers access
Grocery stores have embraced carbon footprint labels
The overwhelming majority of countries still have a substantial unrealized production potential
Gains in Land Productivity: 3 Sources
Growing use of fertilizer
Spread of irrigation
Development of higher-yielding varieties
How to Raise Cropland Productivity
Breed crops that are more tolerant of drought and cold
Multiple Cropping: producing more than one crop a year on the same plot of land
Ministry of Health & Family Planning
Ministry of Energy
Ministry of Water Resources
Ministries of Forestry and Agriculture
Ministry of Transportation
Ministry of Finance
To help & educate people on how not using our natural support system for food transportation is deteriorating us and killing the population
Energy use and diets the effects of shifting from a meat diet to a plant based diet.
What to consider when thinking on how much animal protein to consume
The benefits of life expectancy with people on the high food chain scale versus the low food chain consuming less.
What are the 3 sources that use to give land productivity?
Name 2 ministries that should get involved.
Name a technique that will increase water productivity.
