Celebrating the woman who inspired me (2) – Anna Nagadya, my inspiration to innovate

Vibrant innovation platforms equals relevant research – sustainable gains in research through community involvement

Often, adoption of new technologies or practices designed to improve people’s, lives does not take place due to various factors including lack of understanding by communities and the absence of support for the innovations from leadership. Félix Meutchieye, Cameroon national coordinator of the “Harnessing genetic diversity for improved goat productivity” project speaks about the strides being made by the project in involving communities and increasing the chances of adoption of research findings through innovation platforms.

Felix Portrait_Issue3Harnessing the diversity of native livestock in Africa is becoming a pressing need as continual changes in the environment exert pressure on small holder livestock farmers. The higher temperatures and changing rainfall patterns are contributing to the increased spread of existing vector-borne diseases and the emergence of  new diseases as well affecting the feed production.

Small ruminants play a significant role in livestock production systems throughout the wide range of agro-ecological regions in Africa. For many rural farmers, they are a critical resource of nutrition and income, and goats in particular are more resilient and adapted to different husbandry conditions. It is well documented that genetic variation in ability to various infections and diseases as well as to adapt to harsh environments with higher temperatures and less water, exists between and within different breeds of goats.This adaptation is especially evident in indigenous breeds, but gaps still exist in the knowledge available.

The “Harnessing genetic diversity for improved goat productivity” project is focused on bridging this knowledge gap by helping farmers take advantage of the best genetic resources locally available. Our strategy involves working closely with the goat keepers, traders, policy makers and all other stakeholders so that there is collective ownership of the existing problems and in the approach to finding solutions. Through the innovation platform (IP) system, the project is drawing from the existing indigenous knowledge, receiving guidance in terms of farmers’ actual needs and preferences and establishing effective channels that act as vehicles for information on research findings and promotion of sustainable livestock keeping practices.

Already in Cameroon, one regional IP in Kouoptamo (West Highlands) has identified high fecundity as a desirable trait in their goats and are promoting their animals as high value breeding stock for proven twinning ability. Additionally, as a result of close engagement with the project through the
Cameroon National goat IP, the Ministry of Livestock, fisheries and animal industries has recognized the importance of goats and small ruminants as an important resource to grow the country’s rural economy and has started a program to revitalize three small ruminant breeding and multiplication
stations in different agro-ecological regions.

Our counterparts in Ethiopia have established a community based goat breeding initiative where a group of 50 farmers have formed a cooperative society to drive the breeding activities. The cooperative members brought their goats for selection to form the next generation of goat parents in their village and in the neighbouring villages as well.

I see this active participation by communities as a very exciting and practical way of doing research. Through community involvement, the project has been able to stay relevant and ensure that good science supports the things that are most relevant to Africa’s development.

Getting goat facts straight – ABCF fellow makes a presentation during the 6th All Africa Conference on Animal Agriculture

“There is need for us, African scientists to design research to suit our own context so that we can get the real picture of what we have on our continent.”

This was the powerful message delivered by Getinet Mekuriaw, an Africa Bioscience Challenge Fund (ABCF) research fellow at the BecA-ILRI Hub, during the Sixth All African Conference on Animal Agriculture in Nairobi on 27 October 2014. Mekuriaw’s presentation titled “A review of genetic diversity of domestic goats identified by microsatellite loci from global perspective” was based on a paper authored together with five other scientists from the Addis Ababa University in Ethiopia, the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub and ILRI. The paper was an evaluation of the research that has been done so far in establishing the genetic diversity of domestic goats globally.

Genetic diversity holds the key to animal breeding and selection. Accurate information on the observable characteristics or traits of a species, their form and structural features and how this varies amongst different populations in a given region is crucial in the development of appropriate breeding strategies for the improvement and for the conservation of important breeds.

In Africa, the role of indigenous goats in smallholder livestock production is growing rapidly as keeping them is often the only practical way to use vast ranges of grasslands that cannot be used for crop production. There is evidence of local goat breeds being better able to withstand the increasingly harsh environmental conditions that come with climate change including higher temperatures, lower quality diets and greater disease challenge.

Unfortunately, not enough has been done to generate information about the genetic resources available and it is feared that many goat populations could disappear before they are even identified. Mekuriaw attributed the gaps in knowledge on goats globally, and in Africa specifically, to deficiencies in research methods. While it is indeed possible that there is low genetic variation between goat populations in Africa and beyond due to uncontrolled and random mating within flocks as well as huge population movement in between regions, inefficient technical and statistical data management have contributed to conclusions drawn from research so far.

Mekuriaw, a PhD student from the University of Addis Ababa in Ethiopia, is currently attached to the BecA-led research project “Harnessing genetic diversity for improved goat productivity” under the ABCF fellowship program. Through this component of his PhD research which is supervised at the BecA-ILRI Hub by project Principal Investigator Dr Morris Agaba, Mekuriaw hopes to establish the extent of diversity among indigenous goat breeds in Ethiopia. He also hopes to map out the genes responsible for growth and twinning and thus contribute to the establishment of a breeding strategy that will select goats for those traits. In addition, he is also developing a molecular tool, DNA profiling, which enables the determination of pedigree of the animals which will also be used in the establishment of the breeding strategy.

Mekuriaw’s research is helping the BecA-led project to achieve its overall goal which includes empowering goat breeders in Cameroon and Ethiopia to develop better goats suited to resource-poor farmers and to develop ICT based tools to support management decisions throughout the goat production chain.

Welcome home Brachiaria! Home coming of Africa’s “super” grass

“The hitherto overlooked Brachiaria grasses have returned home to Africa and have been warmly embraced by smallholder dairy farmers in eastern Africa.”

Presenting a paper co-authored by nine scientists from seven institutions including the BecA-ILRI Hub, Dr Brigitte Maas from International Center for Tropical Agriculture (CIAT) gave an overview of the research, successes and challenges of adopting improved Brachiaria hybrids Mulato and Mulato II in the African context during the 6th All Africa Conference of Animal Agriculture in Nairobi on 27 October 2014.

Brachiaria grasses have higher nutrient content than most commonly used forages. They are adapted to drought and low fertility acidic soils. These grasses are good for the environment as they enhance nitrogen use efficiency, sequester carbon, and reduce greenhouse gas emission and ground water pollutions. These attributes make Brachiaria one of the most widely cultivated forages in South and Central America, and Australia where they have been shown to increase milk and meat yields in cattle.

Re-introducing Brachiaria grasses to their native home
Despite the fact that they are native to Africa and that they occur plentifully across many regions of sub Saharan Africa, these grasses are yet to be explored and fully utilized as forage on the continent. However, thanks to the implementation of a Swedish funded research program “Climate-smart Brachiaria grasses for improved livestock production in East Africa” which is led by BecA-ILRI Hub in partnership with CIAT; Kenya Agricultural and Livestock Research Organization (KALRO); Rwanda Agriculture Board (RAB); and Glasslanz, the anonymity of these “wonder grasses” is coming to an end. The heightened publicity of the importance of Brachiaria grasses and as a strategy to mitigate the effects of climate change has resulted in substantial interest in these grasses among farmers, researchers and policy makers across the continent.

While improved varieties developed in Latin America are being tested in Africa, challenges from pests and diseases have been observed on these imported varieties. The grassed developed in South American conditions have already been observed to be vulnerable to spider mites; sorghum shoot fly, and a number of fungal diseases that are currently in the process of identification. This has necessitated a deeper investigation into locally available diverse genetic resource in Africa to identify the pest and disease resistant varieties.

Finding the best local varieties for the African context

Since Africa hosts a high genetic diversity of Brachiaria, the way forward would be the utilization of this untapped genetic resource to breed varieties that are suitable to the African context. The BecA-ILRI Hub-led project is exploring local ecotypes and gene bank accessions of African origin for drought tolerance, pests and disease resistance and biomass yields. This program consists of four main components – evaluating Brachiaria genotypes for drought tolerance and adaptation to marginal soils; evaluating varieties for biomass production, animal nutrition (including feeding experiments) and seed production; identification and use of phytobiomes for potential agricultural applications as bio-fertilizers, bio-pesticides and bio-yield enhancement agents; and the building the capacity of African scientists to conduct research on Brachiaria grasses.

This collaborative research effort is giving renewed hope to millions of smallholder livestock farmers across eastern Africa who operate smallholder crop-livestock mixed farms on less than 10 ha and are at pains to increase their production in a set up where natural grazing is limited or no longer available

Growing healthier sweetpotato – research to combat sweetpotato weevil

YouTube Preview Image

Lydia Wamalwa is a molecular plant scientist with the International Potato Center (CIP) whose research in Kenya is hosted at the BecA-ILRI Hub in Nairobi. Lydia and her colleagues at CIP are working to develop sweetpotatoes that will fight off the sweetpotato weevil without using pesticides.

The sweetpotato is an important food crop in developing countries which account for 95% of the over 105 million metric tons produced each year globally. Its ability to grow in marginal conditions and with little labor and inputs, makes the sweetpotato a source of resilience in food and nutritional security to smallholder farmers. Not only is sweetpotato nutritious to humans (contains vitamin A, B, C and E) but it also provides inexpensive, high-protein fodder for animals.

Unfortunately production of this highly adaptable food crop faces a major threat from the sweetpotato weevil, which often causes losses of 60% – 100% during periods of drought. In this two and a half minute video, Lydia Wamalwa talks about the ongoing research to develop sweet potato resistance to sweetpotato weevil which is supported by the World Bank.

The International Potato Center is among the hosted members of the CGIAR consortium which contribute valued crop biosciences capacity to the BecA-ILRI Hub. Other members of the CGIAR consortium whose research is hosted at the BecA-ILRI Hub include International Institute of Tropical Agriculture (IITA) and the International Rice Research Institute (IRRI).

Fattening the pig industry in eastern Africa: Finding ways to control African swine fever in Kenya and Uganda

Researchers from Kenya, Uganda and Australia chart the way to control African swine fever in East Africa

On 2-3 October 2013, a multi-disciplinary team of researchers who have been studying the patterns, causes, and effects of African swine fever (ASF) in Kenya and Uganda, shared their findings at a project closing workshop.

During the workshop held jointly with the Food and Agriculture Organization of the United Nations’ Emergency Centre for Transboundary Animal Diseases Operations (FAO-ECTAD) the team of researchers from Kenya, Uganda and Australia led by scientists from the International Livestock Research Institute shared data from their two-year long study.

African swine fever, which currently has no treatment or vaccine, is a highly contagious disease in pigs that causes nearly 100% losses in pig herds. Although it does not cause infection in people, outbreaks of the disease cause devastating income losses to farmers, and pig/pork traders. The project, “Understanding ASF epidemiology as a basis for control”, was funded by the Australian government as part of a research partnership between the BecA-ILRI Hub and Australia’s national science agency, Commonwealth Scientific and Industrial Research Organisation (CSIRO).

The discussions generated at the workshop are expected to mark the beginning of a concerted effort to improve pig farming and expand the pig industry in eastern Africa.

As students conducting research on domestic cavies under the BecA-ILRI Hub project –“Improving production, nutritional protein and household income through increased consumption of domestic cavies”, my colleagues Jeanne Wikondi, Youchahou Poutougnigni and I visited the Hub in Nairobi Kenya to acquire skills in molecular biology.

Everything about, our one month stay at the BecA-ILRI Hub was very exciting, starting with the very warm welcome from the staff members which made me feel right at home. The superb planning and the training we received meant that we could already work in the lab within three days of our arrival.

We brought 109 blood samples from domestic cavies which I had collected from mono-modal agro ecological zone in Cameroon and our main task was to assess the genetic diversity of the cavies in this area.

Aside from having a laboratory technician assigned to assist us, we each received a comprehensive manual which enabled us to work independently and all the equipment and chemicals I needed were readily available.

At the end of every week, I attended a four-hour presentation session where all visiting scientists and ABCF fellows made presentation on the progress of their work. These sessions not only allowed research fellows to talk about the challenges they are facing, but they were also an opportunity for us to give each other suggestions on how better to go about our research.

I am very grateful for the training we received at the BecA-ILRI Hub. Not only were we able to establish the genetic diversity of cavies in our study area, but we also feel confident to give advice to cavy farmers regarding rearing of these species. Most importantly, we have acquired the knowledge and tools necessary to apply molecular biology in our research.

In future, we will try to determine which genes are responsible for desirable traits e.g. coat colour, growth rate and prolificacy. We hope that our findings will contribute to the selection and breeding of cavies for increased productivity.

World Food Day: What IS Food?

As we celebrate world food day, perhaps it’s time to stop and ask ourselves “what really is food?”

Food security in Africa is often measured by the availability of the staple starches and animal statistics that focus on major livestock such as cattle, sheep and goats.

Research to help African countries overcome the challenges of food insecurity traditionally focuses on improving staple starches such as rice, maize and wheat. These crops often require heavy inputs, are highly dependent on increasingly irregular rainfall and are also threatened by major crop pests and diseases.

Likewise, research on livestock focuses on large livestock which are faced with major disease threats such as peste des petits ruminants, commonly referred to as PPR in goats and sheep or African swine fever in pigs.

Perhaps it is a high time new avenues to address food security by looking at crops that are adaptable to harsh climatic conditions and more resilient livestock were explored.

The amaranth, for instance, is a hardy, drought tolerant crop commonly regarded as a weed in many parts of Africa. This under-recognized “orphan” crop is especially beneficial for pregnant and breastfeeding women as well as babies and children since its leaves are a good source of vitamins A, C, K and folate, while the grain contains high levels of protein containing essential amino acids and minerals like iron, zinc and calcium.

In many parts of eastern, central and western Africa, domestic cavies or “guinea pigs” as they are commonly known are widely used as meat. Cavies provide high-quality meat with about 19-20% protein as compared to beef or lamb with lower protein contents of 17-19% and the cavy skin that is usually consumed contains even more than 30% protein. Incidentally, this mini livestock has become so important in Peruvian diets that it now has a national day – the National Guinea Pig Day.

Indigenous fruit crops are also greatly understudied yet they hold great promise in feeding the world. One example is the baobab, a common African bushland fruit tree. The fruit and leaves of the baobab are high in vitamin C, the seed and flower are high in protein, and the kernel contains edible oil. This fruit tree tolerates a wide range of vegetation types including scrub, wooded savannah hot, dry areas, and semiarid to sub-humid tropics south of the Sahara.

These are only some of the numerous resources that can be tapped into to provide increased food production, reliable income and high nutrition for a growing world population.

As we think about how to feed the world this World Food day, we could begin by adopting an “orphan” crop or mini-livestock.

Climate-smart Brachiaria Grasses: livestock feed, household cash

A Swedish funded research program led by the BecA-ILRI Hub is improving the adaptation of Brachiaria grasses, an indigenous East African forage crop, to drought and creating forage seed production enterprises to benefit resource poor smallholder farmers in the region.

During the 22nd International Grasslands Congress held in Sydney, Australia from 15-19 September 2013, Sita Ghimire, a plant pathologist and senior scientist with the “Climate-smart Brachiaria grasses for improving livestock production in East Africa” program presented a poster about the possibilities that these highly nutritious grasses present.

By using the genetic diversity of Brachiaria grasses and endophytes found within the host (beneficial microorganisms growing within the plants) the research aims to enhance the drought resilience of the grasses; reduce the conversion of soil nitrogen to greenhouse gas, nitrous oxide; and possibly develop microbe based pesticides and fertilizers with wider applications.
