Development in Brazil: Double cropping helps Brazil’s development

It’s not just about agriculture. Growing two crops a year in the same field improves schools, helps advance public sanitation, raises median income, and creates jobs.

PROVIDENCE, R.I. [Brown University] — New research finds that double cropping — planting two crops in a field in the same year — is associated with positive signs of economic development for rural Brazilians.

The research focused the state of Mato Grosso, the epicenter of an agricultural revolution that has made Brazil one of the world’s top producers of soybeans, corn, cotton, and other staple crops. That Brazil has become an agricultural powerhouse over the last decade or so is clear. What has been less clear is who is reaping the economic rewards of that agricultural intensification — average Brazilians or wealthy landowners and outside investors. (more…)

EAST LANSING, Mich. — Crop diversification with shrubby legumes mixed with soybean and peanuts could be the key to sustaining the green revolution in Africa, according to a Michigan State University study.

The study, which appears in the Nov. 22 issue of the Proceedings of the National Academy of Sciences, states that diversifying crops would boost production of nutrient-enriched grain by 12 percent to 23 percent, said Sieglinde Snapp, a crop and soil scientist at Michigan State University’s Kellogg Biological Station who led the study.

Malawi has been called the cradle of Africa’s green revolution. Through its government subsidizing 90 percent of fertilizer and superior corn seed costs, Malawi has reaped substantial gains in productivity of calorie-rich food. The successful program has had some unintended consequences, though, such as reliance on starchy cereals, expensive fertilizer and depleted soils. (more…)
