Fighting Hunger, Energy Poverty, Deforestation & Climate Change At The Same Time

How biochar works
A nation that destroys its soils, destroys itself. - Franklin D. Roosevelt

Biochar is a carbon-rich product obtained from the pyrolysis of biomass. As the central element of a new and highly promising integrated soil management technique it is capable of halting slash-and-burn farming in the humid tropics by making nutrient-poor, acidic soils productive. As such it offers one of the few sustainable strategies to halt deforestation while simultaneously eliminating hunger amongst subsistence farmers at the forest margins. Biochar doubles as a stable carbon sink, making it a key tool in the climate fight.

Older readers will remember the original "Green Revolution" in agriculture, i.e. using petrochemical-based fertilizers and pesticides. This led to "Silent Spring" and terrible consequences for both animals and humans.

TIME....and TIME again!

Click here for full article "After the Oil Crisis, a Food Crisis?" This a second oil-related article I've found from TIME this week.


"Is the world headed for a food crisis? India, Mexico and Yemen have seen food riots this year. Argentines boycotted tomatoes during the country's recent presidential elections when the vegetable became more expensive than meat; and in Italy, shoppers organized a one-day boycott of pasta to protest rising prices. In late October, the Russian government, hoping to ease tensions ahead of parliamentary elections early next year, announced a price freeze for milk, bread and other foods through the end of January.

What's the cause for these shortages and price hikes? Expensive oil, for the most part."...

"...On the demand side, one of the key issues is biofuels. Biofuels, made from food crops such as corn, sugar cane, and palm oil, are seen as easing the world's dependence on gasoline or diesel. But when crude oil is expensive, as it is now, these alternative energy sources can also be sold at market-competitive prices, rising steeply in relation to petroleum.

With one-quarter of the U.S. corn harvest in 2007 diverted towards biofuel production, the attendant rise in cereal prices has already had an impact on the cost and availability of food. Critics worry that the gold rush toward biofuels is taking away food from the hungry. Jean Ziegler, the U.N. Special Rapporteur on The Right to Food, recently described it as a "crime against humanity" to convert food crops to fuel, calling for a five-year moratorium on biofuel production."

Corn ethanol requirements passed by senators??

Someone on one of my lists just posted this link of a chart presented by Matthew Simmons on corn ethanol requirements recently passed by the senate. Oh boy , this puts "eminent domain" in a whole new light....this means I might have to move to Michigan or Ohio!

Why is Urban Agriculture important?

Why is Urban Agriculture important?

The rapid urbanization that is taking place goes together with a rapid increase in urban poverty and urban food insecurity. By 2020 the developing countries of Africa, Asia, and Latin America will be home to some 75% of all urban dwellers, and to eight of the anticipated nine mega-cities with populations in excess of 20 million. It is expected that by 2020, 85% of the poor in Latin America, and about 40-45% of the poor in Africa and Asia will be concentrated in towns and cities.
Most cities in developing countries have great difficulties to cope with this development and are unable to create sufficient formal employment opportunities for the poor. They also have increasing problems with the disposal of urban wastes and waste water and maintaining air and river water quality.

Urban agriculture provides a complementary strategy to reduce urban poverty and food insecurity and enhance urban environmental management. Urban agriculture plays an important role in enhancing urban food security since the costs of supplying and distributing food to urban areas based on rural production and imports continue to increase, and do not satisfy the demand, especially of the poorer sectors of the population. Next to food security, urban agriculture contributes to local economic development, poverty alleviation and social inclusion of the urban poor and women in particular, as well as to the greening of the city and the productive reuse of urban wastes (see below for further explanations and examples).
