Conserving agricultural resources Greenaccord Conference October 2014 Gary gardner Worldwatch institute
Why this topic? • Of UNEP’s 26 emerging issues, ensuring food security is ranked • #3 by scientists • #2 by major groups and governments • Preview of State of the World 2015 • Builds on State of the World 2014
The plan Today Message: The world’s agricultural resource base is being eroded in ways that is affecting food security Outline: • I. The Problem is Now: a Case Study • II. The Damage to Land, Water, and Atmosphere • III. Why is Resource Loss Important? • IV. The Need for Ethical Governance
Worst drought in 109 years • Reduced surface water for agriculture by 36 percent • Groundwater cannot compensate • Nearly 5 percent of the state's irrigated farmland is fallowed • Economic toll: $2.2 billion, 17,000 lost jobs
Climate and land loss, too… • Climate change: droughts jeopardize water “savings accounts” • Aquifers harder to replenish • Snowpack to decline by 12-40 percent by mid-century. • Land loss to urban development: • 2008 -2010, equal to 3/4 the area of San Francisco. • Similar trends for the world • Even as global demand will increase by 60 percent by 2050
ii. Damage to Land, Water, and climate • US: 9.3 million hectares (=Indiana) lost to development, 1982-2007 • Global: 15 to 24 percent of world's land is degraded. • Less vegetation = more climate change, reduced ag yields
Water scarcity • Agriculture: two-thirds of water withdrawals in most economies • Irrigated farmland • 16 percent of arable land • 44 percent of the world's food. • Limited potential to increase irrigated area. • FAO views water as the binding constraint for food production in the Middle East and North Africa
River Basins • Many river basins now "closed“ • domestic, agricultural, and industrial water competes with ecological needs • 405 river basins with 75 percent of global irrigated area: • In 201, severe water scarcity for at least one month per year • In 35, severe water scarcity for at least half of the year. • Tension: Ethiopian dam on the Nile.
Aquifers—Increasingly Drained • 2012 study: 20 percent pumped faster than recharged • Satellite data: Tigris and Euphrates basins lost water equal to volume of the Dead Sea, 60 percent from overpumping • Similar depletions found in India, North China, North Africa, southern Europe and the United States.
Climate change • Changes in temperature, precipitation, and CO2 harm crops at the global level • IPCC: net yields could decline 0.2-2.0 percent per decade • Yet demand to increase by 14 percent per decade. • Or worse? Layer climate studies on hydrological studies, output losses are doubled
IiI. why care about resource Loss? Since 1961: a 2.5- to 3-fold increase in ag output
Because of hunger amid rising demand… • More than 800 million people--one out of 9 persons—are chronically hungry. • Growing prosperity increases demand for grain-intensive livestock products. • Demand up steadily—2.2% annually between 1961 and 2007.
…as Biofuels Boost demand further • Biofuels eat up • 40 percent of US coarse grain production • 50 percent of Brazil's sugar crop, and • 80 percent of EU oilseed production • A “new market fundamental" that drives up prices (FAO)
…And Strategies for securing food may not be sustainable • To date, Intensification • Farmers boost yields using mechanization, fertilizer, new seeds, irrigation • Fishers use high-tech trawlers, and aquaculture • Emerging strategy: imports
Countries dependent on imported grain The number of exporting countries also increased, by 29 percent, from 21 to 27.
Iv. The need for ethical governance • Goal: create a new ethic for food and agriculture • Food as sacred • Ag resources as strategic • Farming as dignified and life-giving • Milan Protocol helps to advance these goals • Roles for governments, industry, cooperative sector, individuals
Government For the heavy lifting
Protect Farmland • Easements, purchases • Agricultural zones that preserve farmland • Programs to prevent degradation
Increase water productivity • Water footprint benchmarks for crops • Crop-shifting away from thirsty crops, where needed • Assist poor farmers with efficient irrigation technologies
Enshrine a right to food • Safeguards needed to protect countries dependent on international markets for food. • Long pedigree • Ensure that it provides food security to importing countries
three resource reservoirs • Governments may need to assess the resource load represented by • Biofuels • Food Waste • Excessive Meat Consumption • Huge potential to alleviate scarcity
Private sector Innovation and resources
Private sector • Core business practices • No to speculation on food and farmland • Promote sust ag practices among suppliers • Marketing practices • 2-for 1 deals • In-house practices • “Just-in-time" delivery • “No-tray” cafeterias
Cooperative sector An underdeveloped alternative
Cooperative sector • Cooperative businesses • Commons management
individuals More powerful than we imagine
Market power, power of example • Favor investments for smallholders, cooperatives, and microfinance • Develop a no-waste ethic vis-à-vis food and water • Support small, local farmers, through CSAs, farmers markets, etc
