In a poor region of northern India, a novel way of growing rice and other crops has quadrupled some yields while using less seed, water, and fertilizer. The approach promises to be an important hedge against climate pressures. But some scientists doubt the reported gains are real.
From The World archives: A community high up in the Peruvian Andes is reviving ancient agricultural practices to help weather climate changes.
An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
This Phys.org article introduces a new way to forecast how food is grown that includes both crop changes and climate change models. The Agricultural Model Intercomparison and Improvement Project (AgMIP), explained in Nature Climate Change, takes into account greenhouse gas, temperature increases and precipitation changes that will affect the yield of crops annually.
"The improved crop models can help guide the world’s developed and developing countries as they adapt to changing climate and create policies to improve food security and feed more people," said Bruno Basso, Michigan State University ecosystem scientist and AgMIP member.
This new technology is part of an effort by agriculturalists to grow more food with less water.

A levada is an irrigation channel or aqueduct specific to the Portugese island of Madeira. They were created from the sixteenth century to carry water across the island from the mountainous west and northwest of the island to the drier southeast, which is more conducive to habitation and agriculture
The total levadas network extends over 2150 km in this island 57 km long, 23km wide in the widest point.
“Mexico, Land of Amaranth,” is the name Delano chose for the non-profit she founded to help impoverished women grow amaranth in small kitchen gardens.
It’s a plant that has evolved very little. It still has characteristics of wild plants. The seed is very little, very problematic to sow it. So we need to work on all of those things so we can have better varieties and in that way expand the surface area of where amaranth is grown.
Each day is a risk to the farm. In fact, that’s why some people have left their little fields to do something else, because the fields aren’t profitable anymore.
GMO Lunch? Uganda Debates Disease-Resistant Cassava
Cassava is a vital staple in Africa and one of the most climate-resilient crops anywhere. It’s also highly susceptible to viral diseases. In Uganda, scientists are testing a virus-resistant transgenic variety, which they hope to introduce for free. But it’s run into a buzzsaw of hostility to genetically modified foods. Can this—or any—GMO succeed in the face of such determined opposition? Should it? Jon Miller reports from Uganda as part of our series “What’s for Lunch.”
