‘A team of researchers at International Livestock Research Institute (ILRI) are testing Napier, Rhodes and Brachiaria grasses for cattle feed, and then physically measuring the emissions in a respiration chamber within the institute’s laboratory.
‘”The study will help African countries monitor, measure, verify and report their emissions with the aim of reducing their nationally determined contributions [NDCs],” said ILRI principal scientist Klaus Butterbach-Bahl. . . .
‘”The measurements will help find better locally available tropical feed for the region as opposed to overreliance on feeds from the temperate world,” he said.
The ILRI study, which started three weeks ago, is the first of its kind on the continent. It involves 18 cows of Boran breed, and will go on for the next five months.
. . . According to Daniel Korir, one of the researchers, the study is also testing the best way to grow the grasses. . . .
It is estimated that more than 70 per cent of African agricultural greenhouse gas emissions are due to livestock production, dominated by emissions from enteric fermentation, a process in which the animals produce methane through digestion. . . .
Africa accounts for 3.8 per cent of global greenhouse gas emissions, compared with the largest emitters China, the United States, and the European Union, that account for 23, 19, and 13 per cent respectively. . . .
