These people live in parts of the world where their diets are dominated by staples oe foods such as rice, wheat, cassava,
Renaissance s roots are in Moscow, where Jennings maintains his primary residence, and his business strategy involves positioning the firm to capture the investment flows between the emerging markets, particularly Russia, Africa, and Asia.

and Israeli technology, have taken root in Uganda, Kenya, and Ethiopia. Tens of thousands of workers carefully harvest the flowers,
Africa s#oeforgotten#crops, including cassava, sunflower seeds, and cowpeas, have in the last two decades rapidly expanded in production, bringing unexpected benefits.#
Consider cassava, a protein-rich root that in Latin america goes by the name manioc or tapioca and
whose heartiness has earned it the nickname#oethe Rambo of crops.##In Nigeria alone, output tripled from the mid-1980s to the mid-2000s to reach 45 million metric tons per year, according to figures from the Food and agriculture organization of the united nations.
Each additional million metric ton is enough to meet the cassava needs of 22 million Africans.
One reason for the cassava miracle has been the ongoing breeding of improved varieties that are more resistant to disease, pest, and drought.
Dried cassava is increasingly being turned into an easily stored flour called gari in West Africa, that is convenient to cook
The Gates foundation is funding tens of millions of dollars of cassava-related research. One project, led by the Donald Danforth Plant science Center,
aims to raise cassava productivity through genome-based breeding, looking at the variations in the plant s DNA to more quickly identify those strains and traits with the potential to boost yields.
A parallel success occurred with cassava. Starting in the 1970s, researchers in Nigeria successfully bred varieties of cassava that are more resistant to pests
and disease, mature faster, and are lower in cyanide. Now Nigeria is the world s top producer of cassava.
Felix Nweke, an international cassava expert, has described the transformation as#oean important scientific success story.#
#Targeted subsidies to farmers, which have long been accepted in Europe, the United states, and parts of Asia, are also becoming more common in Africa, thereby raising farmer incomes and output.
Here, hearty cassava is a natural choice. Indeed, hotter temperatures and and less rain may actually result in higher cassava yields,
according to climate scientist Andy Jarvis, lead author of a 2012 paper in the journaltropical Plant Biology.
Colombia, found that cassava outperformed potatoes, maize, beans, bananas, millet, and sorghum in tests of 24 climate-prediction and crop-suitability models.

Plants grown in the hydrogel membrane spread their roots throughout the top of the film.

Professor Edward Cocking Director of The University of Nottingham's Centre for Crop Nitrogen fixation has developed a unique method of putting nitrogen-fixing bacteria into the cells of plant roots.
and Penn State researchers uses digital photography to provide a detailed image of roots from mature plants in the field.
The roots are photographed then against a black background using a standard digital camera pointed down from a tripod.
The resulting images are uploaded then to a server running software that analyzes the root systems for more than 30 different parameters--including the diameter of tap roots root density the angles of brace roots and detailed measures
of lateral roots. Scientists working in the field can upload their images at the end of a day and have spreadsheets of results ready for study the next day.
In the future the system could allow scientists to study crop roots over an entire growing season potentially providing new life cycle data.
As the plants within all those chambers grow a camera attached to a robotic arm takes thousands of images of cells seeds roots and shoots.
The bacteria were able to swim towards roots, become absorbed by the roots, and then release hormones to stimulate growth.
