BIOFUELS, BIODIVERSITY AND ENERGY SECURITY: What are the environmental and

social impacts?

Converting food crops into biofuel “is a crime against humanity.”

Jean Zeigler, United Nations Special Rapporteur on the Right to Food, October 2007

Energy security

“Let’s face it. It’s all about olive oil.”

And of course the threat of climate change

But another concern is rural livelihoods. What does bioenergy mean for farmers?

Domestic use of roundwoodfor fuel:• 98% in Lebanon• 66% in Jordan• 44% in Turkey

Nepal: 90% of energy comes from fuelwood

Globally, 2 billion people rely on traditional biomass fuels.

Our modern societies are dependent on high energy use

“Can you believe it? Since we installed our wood-burning stove we’ve spent next to nothing on heating oil.”

What about alternative What about alternative sources of oil?sources of oil?

Alberta’s tar sands contain billions of barrels of oil, but current yield is only 1 million barrels per day and requires 3-10 barrels of water for each barrel of oil. Maximum possible production: 3 million barrels per day

Coal remains a major source of energy

We need to look at all the options

Ethanol Feedstock

Biodiesel Feedstock

Some market information… Biofuel market development during

the last 5 years: now ~3% global gasoline consumption

Biofuels may share ~10% of world fuel use for transport by 2025

Less than 10% of global biofuels production is internationally traded

But important expansion in global trade: key consumers (EU, US, and Japan) will not have the domestic capacity to meet internal demand

BiodieselProduced from seeds such as palm, jatropha, canola, sunflower and soy

Rail line between Mumbai and Delhi is planted with Jatropha and the trains run on

15-20% biodiesel

Dangers of Jatropha

Highly invasiveUseless for food or fodderRequires water and fertilizerRequires processing facilities

2000-2005, Indonesia planted 1.6 million haof oil palm, with US$110 million in governmentsubsidies. 9.8 million ha of forest were lost.

One million jobs, mostly low-paying

How can smallholders work with large processors?

Using US maize to produce ethanol increased tortilla price in Mexico

The cost of producing Beer in Germany is increasing, as farmers turn from growing barley to growing biofuels

The European Commissioner for Agriculture cancelled subsidies for set-asides in 2008, because of demand for biofuels. The EU has mandated that biofuel must provide 5.6% of transport energy by 2010.

Policy may have gotten ahead of science

“Second generation” biofuels

produced from agricultural waste, wood and grasses

This…. …or this?

Iogen

Iogen has been producing cellulosic biofuels since 2004. 2008 production: 80 million litres

And what aboutthe small farmer?

Colorado’s Solix Biofuels harvests algae with a field of bioreactors that take a kind of painter’s dropcloth to bubble CO through its system

“Third generation” biofuels?

Marine algae: 10 times the oil content of oil palm(Botryococcus braunii produce 75%of their dry weight as hydrocarbons)

On energy the answer is easy

Potential Reductions in GHG Emissions by Feedstock Type

On climate, it’s also clear what is the best feedstock

Social justice raises more difficult issues

Some key complexities of bioenergy remain

Diverse components: Feedstock supply, conversion technology, and energy use

Diverse economic, social, and environmental factors

Diverse scales, from local to international Diverse objectives, from energy autonomy

at the local level to serving international markets

What should be the basis for the necessary trade-offs?

Three main systems of biomass production for energy

System 1. Small-holder production for local use

System 2. Small-holder production with commerical processing

System 3. Medium- and large-scale commercial production

System 1. A multifunctional landscape with bioenergy potential

System 2. Canola in France is often sold commercially by smallholders

Enkoping, Sweden: First Europeantown powered by bioenergy

System 3. Maize and sugarcane are often grown commercially for external markets

The US has 113 ethanol distilleries and 77 more are under construction. Potential capacity: Over 44 billion liters (about 5% of US fuel consumption)

Gain clear understanding of economic, environmental and social impacts of bioenergy production & trade before making policy

Be guided by risk assessment of comparative advantages, land availability and food security impacts

Encourage investment on better environmental technologies and practices for all renewable sources of energy

Do not expect biomass to be a main source of energy – conservation often remains the most cost-effective option

Use overall land use plans as the basis for planning bioenergy production at the landscape scale
