Pigs: Montfort Boys Town, Fiji
Before 1996, Montfort Boy's Town, a school for disadvantaged boys in Suva, Fiji, taught students how to raise both food and funds by farming fish in ponds. In 1996, ZERI and Professor George Chan arrived, proposing a new integrated farming system that would expand their current efforts into FIVE healthy new enterprises by simply gathering the waste generated by a local brewery. These new revenue ...

Competitive interactions between cultivated and red rice as a function of recent and projected increases in atmospheric carbon dioxide
Because wild lines of the same species often represent a weedy constraint to cultivated crops in the field, any differential response to atmospheric carbon dioxide concentration, [CO2], may alter weed–crop competition and seed yield. We evaluated the growth and reproduction of cultivated rice (Oryza sativa L.; Clearfield, CL161) and red or weedy rice (Stuttgart, StgS) in monoculture, and at two ...

A hotter planet means less on our plates
In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...

Can bats reduce nut farmers’ pesticide use?
Ecologist Katherine Ingram is on a quest to quantify the economic value of insect-eating bats in walnut groves. For the past three years, Katherine Ingram has had a most unusual summer job: catching bats and studying their droppings to see what they eat. A doctoral student in ecology at the University of California, Davis, Ingram is exploring the role bats can play as winged soldiers in the ...

Multisensor Capacitance Probes for Simultaneously Monitoring Rice Field Soil-Water-Crop-Ambient Conditions
Abstract: Multisensor capacitance probes (MCPs) have traditionally been used for soil moisture monitoring and irrigation scheduling. This paper presents a new application of these probes, namely the simultaneous monitoring of ponded water level, soil moisture, and temperature profile, conditions which are particularly important for rice crops in temperate growing regions and for rice grown with ...

Access to Energy: Empowering India’s Rural Communities
Tucked away in the southwestern corner of Odisha in the Bay of Bengal, the village of Keragam is home to around 230 families, most of whom are farmers. They live about 30km from the nearest town, while the state capital, Bhubaneswar, is an 11-hour drive away. Those who work the land here do so in relative isolation; they grow rice and sugarcane as best they can, in a patchwork of green and brown ...

Can We Prevent A Food Breakdown?
By Lester R. Brown As food supplies have tightened, a new geopolitics of food has emerged—a world in which the global competition for land and water is intensifying and each country is fending for itself. We cannot claim that we are unaware of the trends that are undermining our food supply and thus our civilization. We know what we need to do. There was a time when if we got into trouble ...

Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

The developing world is awash in pesticides. Does it have to be?
Herbicides, insecticides and fungicides threaten the environment and human health in many parts of the world. But research is pointing to a better approach. In today’s globalized world, it is not inconceivable that one might drink coffee from Colombia in the morning, munch cashews from Vietnam for lunch and gobble grains from Ethiopia for dinner. That we can enjoy these products is thanks, ...

Could food shortages bring down civilization?
One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...
