Rice yields could plummet 40% by 2100 due to climate change

November 22nd, 2019 / Down to Earth

Global yields of rice, the world’s largest staple food crop, could plummet by as much as 40 per cent by 2100, affecting two billion people, a new study by Stanford University in the United States has said.

The plummeting of the yields would be caused by increasing temperatures. Moreover, changes in …

New gene-edited canola variety resists deadly disease, expected to drastically boost crop yields

November 15th, 2019 / ISAAA, US

Three new traits for canola, which can increase crop yields and reduce harmful environmental impacts, has been developed by Cibus, a biotechnology company that has pioneered precision gene editing for agriculture. The new traits pertain to pod shatter, resistance to Sclerotinia, and weed control.

The new traits precisely edit the canola genome to reduce pod shatter, the tendency …

GMO wheat varieties boost crop yields 20-30% in field trial

October 9th, 2019

Studies conducted at the Australian Plant Phenomics Facility (APPF) showed experimental genetically modified (GM) wheat lines [have] the potential to significantly increase yields. These lines ‘overexpress’ three wild-type plant genes, either individually or in combination, and were developed to test whether targeting individual wheat genes could lead to improvements in yield.

In greenhouse studies conducted at …

The determinants of crop yields in Uganda: what is the role of climatic and non-climatic factors?

March 2nd, 2018 / Agriculture & Food Security

Background: It is widely accepted that crop yields will be affected by climate change. However, the role played by climate in affecting crop yields vis-a-vis non-climatic stresses, is often unclear, limiting decision choices around efforts to promote increased production in light of multiple stresses.
Results: This study quantifies the role of …

Rwanda: Meet the retired soldier making millions from growing improved sweet-potato

November 8th, 2017 / New Times

Jean Marie Vianney Habumuremyi says he had previously looked at sweet potatoes as for only home consumption. Then he received a new variety of potatoes from a USAID project. The new orange-fleshed sweet potato variety can produce eight tonnes per hectare, four times as much as his former crop. This …

Ethiopia: Increasing nutrient-use efficiency

December 20th, 2016 / The Ethiopian Herald

Intensive high-yield agriculture is dependent on addition of fertilizers, especially industrially produced NH4 and NO3. In some regions of the world, crop production is still constrained by too little application of fertilizers. Without the use of synthetic fertilizers, world food production could not have increased at the rate it did …

Nourish Africa’s future by improving diets and eliminating malnutrition

November 24th, 2016 / AllAfrica.com

Poor early childhood development is estimated to lead to the loss of roughly a quarter of average adult earning potential. Across the African continent, the economic impact of malnutrition is estimated to be as high as $25 billion per year, with countries losing between 3 per cent and 16 per …
