Redesigning Agricultureto improve efficiency Olivia Cox CPSP218L Sec. 0201
Why Redesigning Agriculture Is Important: • Need to feed growing population • Lack of land left for farming • Water shortages • Grain for fuel turns out to cause more harm than good • Protein is being produced inefficiently
Current Issues In Agriculture:Feeding A Growing Population • World pop. = 8 billion. World pop. starving or malnourished = 1 billion (1/8 of the entire pop.!) • Reducing population would reduce demand for food • Consumption of unhealthy amounts of livestock products (esp. in US) • FIX: • Reproductive health care & birth control services • US eat lower on food chain
Current Issues In Agriculture:Lack Of Land Left For Farming • Lack of land leads to need to increase productivity • Acquisition of vast tracts of farmable land by foreign countries • FIX: • Invest $ in helping low-income countries develop their potential for expanding food production, enabling them to export more grain • Raise land productivity by 1.) raising irrigation efficiency 2.) producing larger-yielding hybrid strains
Current Issues In Agriculture:Water Shortages • Need for more efficient irrigation systems • FIX: • Shift from less efficient flood or furrow systems to overhead sprinkelers or drip irrigation • Insitutional shifts—moving the responsibility for managing irrigation systems from govnt agencies to local water users associations
Current Issues In Agriculture:Inefficient Protein Production • 36% of the world grain harvest is used to produce animal protein • World meat consumption increased from 44 million tons in 1950 to 260 million tons in 2007 • Cattle: takes roughly 7kg grain to produce a 1kg gain in live weight • Pork: over 3kg grain per kg of weight gain • Poultry: over 2kg grain per kg weight gain • Herbivorous fish (carp, tilapia, & catfish): less than 2kg grain per kg weight gain • FIX- • Soybeans as a protein source, switching to fish, eating less meat
Current Issues In Agriculture:Grain For Fuel Does More Harm Than Good • The 104 million tons of grain used to produce ethanol in 2009 in the US is the food supply for 340 million people at average world grain consumption levels • FIX: • Could focus on providing better ways of transportation, public trans etc. • Removing incentives for converting food to fuel http://blogs.princeton.edu/chm333/f2006/biomass/ethanol%20cornheap.jpg
