A recent study by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub and the Kenya Agricultural and Livestock Research Organization (KALRO) shows that farmers in semi-arid region of Kenya could stall the adverse effects of climate change on their farms by planting drought-tolerant Brachiaria grass.

The study shows that Brachiaria grass not only improves the productivity of livestock but that it also contributes to improved soil health. Arid and semi-arid lands (ASALs) make up 83 per cent of the total land area in Kenya, which have marginal to low potential for crop production. The soils in these areas are low in plant nutrients and are prone to erosion.

The report Effects of Brachiaria grass cultivars on soil microbial biomass carbon, nitrogen and phosphorous in soils of the semi arid eastern Kenya is one of a compilation of 24 papers published on diverse studies carried out on Brachiaria grass with regards to its adaptation to drought; its impact on milk and meat production; its role in improving soil quality; and establishment of seed production systems for increased availability of the grass seeds and income generation.

Sita Ghimire, a co-author and co-editor of the report and senior scientist at the BecA-ILRI Hub leading the Brachiaria research, says the report is a culmination of pioneering research on the forage in East Africa.

Brachiaria has been used to transform livestock production in South America,’ says Ghimire, ‘however, despite the immense benefits it demonstrated in that region, the true potential of this grass is yet to be realized in its motherland, Africa.’

Livestock production in Kenya accounts for 10 per cent of the gross domestic product (GDP). With growing population, increasing affluence and changes in food habits there is an increasing demand for livestock products. Over 70 per cent of all the livestock in Kenya is found in ASALs, necessitating research to develop forage options that will sustain increased livestock productivity in the face of climate change.

The collaborative research of the BecA-ILI Hub and KALRO demonstrates that the cultivation of Brachiaria grass improves soil quality by increasing the amount of plant available carbon, nitrogen and phosphorous.

    Since posting this article, the BecA-ILRI Hub has received numerous requests from farmers for seed/cuttings of this grass. We would like to acknowledge each and every farmer who has sent in their request.

    While the national agricultural research program, Kenya Agricultural and Livestock Research Organization (KALRO formerly KARI) does not have seed available for distribution at the moment, they are working hard to develop a database of farmers in different areas across the country who can supply cuttings.

    We will share post this information as soon as it is made available!
