Three ways to tackle Napier grass diseases in East Africa

An ASARECA-funded Napier grass smut and stunt resistance project held its final workshop on 2 and 3 June 2010 at the International Livestock Research Institute (ILRI), in Addis Ababa, Ethiopia. It gathered 30 participants from Kenya, Tanzania, Uganda, UK, and Ethiopia.

During the workshop, participants shared three main ways to tackle these diseases that attack an important feed for cattle: One is to identify alternative forage species. The second is to raise awareness of the disease and better management methods among farmers. The third is to control the vectors causing the diseases or to breed disease-resistant grasses.

It all started in 2007, when ASARECA – the Association for Strengthening Agricultural Research in Eastern and Central Africa, the International Livestock Research Institute, Rothamsted Research, Kenya Agriculture Research Institute, National Agricultural Research Organisation (Uganda) and the National Biological Control Programme (Tanzania) launched a three year project to examine the problems.

The project brought together scientists from national and international institutes to find ways to halt the spread of the diseases that affect Napier grass – an important feed source for dairy cattle in the region.

The project aimed to determine the extent of the disease problem in areas where smallholder dairy is important, to collect Napier grass clones that farmers select as more resistant to the diseases and to identify best management practices used by farmers to reduce the impact of the diseases.

With the vision and financial support of ASARECA, this project has characterized Napier grass clones, developed diagnostic techniques for use in the region, and formed local partnerships to share information and management practices.

During the two day meeting, participants set out different approaches to fight the disease. One is to identify other alternative forage species.

“Before we were growing Guatemala grass, says Peter Ddaki, workshop participant and farmer in Kitenga, Uganda. It was less tasty and hard to cut but we could go back to it because if this disease is not fought, we go to poverty”. “It is true violence to me”, he adds. “From my cows, I have three things: urine, milk and manure. Well, they have all reduced. My suggestion to researchers is to think about Guatemala grass or other forages in case Napier grass dies away.”

Jolly Kabirizi, senior researcher at the National Livestock Resources Research Institute (NaLIRRI) and project partner from Uganda is one of several researchers in the region looking more closely at other forages, such as the Brachiaria hybrid cv Mulato, and investigating feeding with crop residues. Jean Hanson, ILRI Forage diversity team leader, explains: “In this project we made the choice to focus on Napier grass and looked for a disease resistant variety of the same species because it is very difficult to find anything as productive as Napier and for farmers to change to other grasses for cut and carry systems. Guatemala grass does not have the same palatability as Napier grass, and Brachiara Mulato produces less biomass. We also carried on with research on Napier because its dissemination with cuttings is much easier than with the other grasses.”

Another approach is to raise awareness among farmers. Presentations showed that in the districts where the diseases were studied, over 80% of the farmers are now aware of the disease symptoms and adopt recommended best management practices. The incidence and severity of stunt especially, is really dropping (decline of 20 to 40% in Uganda and Kenya, more in Tanzania where it is an emerging disease) even though there is still a need to raise awareness to avoid spreading the disease. As Peter Ddaki puts it “don’t leave supervision of your garden to children or people who don’t know about the disease; use clean material when planting, or stunt will wipe out your entire crop.”

In Uganda, manure application seems to be the most effective control measure as it reduces Napier stunt incidence but also improves fodder yield. Similarly, in Tanzania and Kenya, a critical research area is the development of Integrated Pest Management.

A third approach is to look at the causes of the diseases and find ways to control the vectors or to breed disease-resistant grasses. Scientists from the International Centre of Insect Physiology and Ecology (ICIPE), Charles Midega and Evans Obura explained the importance of analyzing the biology of the disease and its vector. “Kenya is so far the only country where we identified a leafhopper vector (Maiestas (=Recilia) banda) transmitting Napier stunt disease”, says Evans Obura, Doctoral research fellow with ICIPE, “there could be other insects. We are at the moment working on identifying a phytoplasma (cause of the disease) resistant Napier grass cultivar and also studying the genetic diversity of Recilia banda in eastern Africa.”

But as Charles Midega pointed out: “if the resistant variety has high levels of resistance to the vector, where will the vector move to in the future? Food crops? And will food crops such as maize and millet be susceptible to phytoplasma?” This scary thought triggered numerous comments in the discussions.

On a positive note, Margaret Mulaa, senior researcher at the Kenya Agricultural Research Institute (KARI), has identified 28 clones that are not showing symptoms and appear disease resistant in the field in an area of high stunt incidence. These still need to be tested by farmers to confirm their yields and disease resistance before further distribution.

Fishbowl session at the Napier Grass diseases workshop Besides presentations, the workshop used participatory methods such as Fish Bowls and World cafes to encourage discussions. Facilitated with brio by Julius Nyangaga and Nadia Manning-Thomas, these lively sessions were sometimes new to participants and much appreciated. They particularly helped the project team interact with decision makers and regional stakeholders.

It was clear from the group discussions that the project created awareness, trained scientists, mentored graduate students, plus identified materials and set up efficient networks.

Alexandra Jorge, Coordinator of the Global Public Goods Project, commented on the progress made in the three year project: “It is amazing to see the amount of knowledge people have accumulated when you compare the first meeting I attended in 2007 and this one! I also notice the ownership and commitment participants feel about their work” and she adds “I was impressed with how much people involved did at all levels in only three years…”

In her closing remarks, Sarah Mubiru from ASARECA shared a story illustrating the power of collaboration: In her story, a man brought to God asks to see Hell and Heaven. In Hell, people have bowls of soup but spoons that are too long to drink with or eat from. In Heaven, people with the same bowls and long spoons feed each other. The first results in chaos, the second in harmony.

She said that ASARECA similarly prides itself on its partnerships, carrying out fruitful partner-based research that improves livelihoods. ASARECA funds projects that “work locally” and have regional impact through linkages and dissemination.

She concluded that this project has achieved that goal with strong national teams addressing local issues, working together across the region to support each other and using the website to make the project results available world wide.

These sentiments were reflected by ILRI Theme Director Shirley Tarawali: “The strong collaborative nature of this project will hopefully last after the end of the project”.

Overcoming the Napier grass disease threat to East African dairy farmers

Also called elephant grass, Napier grass is planted on farms across East Africa as a source of feed for dairy cows. Farmers cut the grass for their livestock, carrying it home for stall feeding.

It is the most important forage grass in the region, constituting 40 to 80% of forages used by smallholder dairy farmers. In Kenya, half a million smallholder dairy producers rely on Napier grass to feed their cows. In Uganda, 90% of farmers rely entirely on Napier grass as fodder for their improved dairy cattle.

The livelihoods of these farmers are threatened by outbreaks of stunt and smut diseases affecting the Napier grass. To tackle the threat, the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) funded a three-year project to determine the extent of the disease problem, to collect disease-resistant Napier grass clones identified by farmers, and to identify best management practices used by farmers to mitigate the impact of the diseases.

After three years researching the problem in Kenya, Tanzania and Uganda, project researchers from the International Livestock Research Institute, Rothamsted Research, the Kenya Agriculture Research Institute, the National Agricultural Research Organisation (Uganda) and the National Biological Control Programme (Tanzania) will meet with colleagues from the region to share results and recommendations, promote good practices and draw other scientists into the project.

The workshop will be held at ILRI Ethiopia from 1 to 3 June, 2010.

Inauguration of a new forage diversity lab at the International Livestock Research Institute in Ethiopia

A new forage diversity lab was inaugurated yesterday afternoon, Monday 12th April 2010, at the International Livestock Research Institute (ILRI) in Addis Ababa, Ethiopia, in the presence of the ILRI board members, the forage diversity staff and guests. Jean Hanson, forage diversity leader, looked pleased at the result, and with emotion she spoke of the lab achievement. “It is an ILRI Ethiopia lab” she said, “it will give us and students much more space to work and has now allowed all the equipment that was previously scattered to be centralised. This will also help us and our National Agricultural Research Systems (NARS) partners to be cost effective.” The construction work started in December 2008 and the building was actually ready for the board meeting which took place in Addis in November 2009. The finishing touches, supervised by Jean Hanson, were added and the spotless lab is now ready to use. Prior to the visit to the lab by participants of the inauguration, was a very symbolic planting of two Acacia Tortilis trees which will, in a few years, give shade to the molecular lab. The Chairman of the board, Knut Hove, put on his gardening gloves and efficiently planted this indigenous, dry land tree, commenting that it was “the best possible tree we could have for this lab”. Dr Hanson then emphasized that the genebank not only works on conservation of forage diversity but also on improved use of diversity for better forages which requires more molecular work with newer techniques. “The lab will allow us to work more with our sister centers of the CGIAR”, she stated, “and the nicest thing would be to bring a group of students together, who will energize the group, emulate each other, share and learn, because a major role of CG centers is capacity building.” Furthermore, considerations for equestrian arena construction near me will be explored in future developments. According to Dr Ananda Ponniah, in charge of capacity strengthening at ILRI, “there is now space for more students and therefore we can also diversify students, have them coming from Ethiopia but other countries as well.” After the official cutting of the ribbon by Knut Hove and applause, the visit was led by Janice Proud, Project coordinator of the Napier grass smut and stunt resistance project, and Alexandra Jorge, Global Public Goods Project Coordinator (SGRP/CGIAR). Janice Proud explained how the new lab would help the work on Napier grass diseases, smut and stunt, which cause feed loss in Kenya, Uganda and Tanzania. “The new facility will allow us to use PCR techniques in real time. We also have some students looking at milk proteins. The beauty of a molecular lab is that you can use it for different projects”, she concluded. Alexandra Jorge talked about tissue culture and how the space would now allow the Centre “to have one dedicated area for tissue culture and therefore avoid contamination”. She also feels that the new lab will help to link better with ongoing projects such as the Napier grass project because “vegetatively-propagated crops like Napier grass can greatly benefit from production of clean plants and distribution of in vitro materials”. “We hope that a lot of publications will follow!” added the Chairman of the board. Mr Traoré, board member, also expressed that “the lab nicely complements BeCA (Biosciences eastern and central Africa) in Nairobi. Students in Ethiopia will be able to do the preliminaries here then go to BecA to make use of more sophisticated equipment.” As a final word, the board Chair summed up the achievement by stating that “the whole building smelled of a brand new lab which is exciting for new students to come and work, get their hands dirty and green!”

Re-assessing the fodder problem

Small-scale farmers depend largely on their animals and need to feed them well. However, several factors threaten its supply. Technology based innovations have been the mainstream solution to improve the fodder problem. But making farmers find relevant information and networks appears to be as effective for innovation. An ILRI project looks at the issue from a different point of view and discovered that the problems related to fodder availability have just as much to do with access to knowledge as with access to appropriate technology. This article in the March 2010 issue of ILEIA’s ‘Farming Matters’ magazine profiles the DFID-funded Fodder Innovation Project.

Pastoral reciprocity: A lesson in community ethos

Impacts of drought in Kitengela in 2009

We heard today from Mohamed Said, a scientist leading research at the International Livestock Research Institute (ILRI) on pastoral rangelands in eastern Africa, that Kitengela, a Maasai rangeland neighbouring Nairobi, is turning green again after good recent rains following last year's devastating drought, which the livestock herders in Kitengela say killed most of their livestock along with much of the area's wildlife. Interestingly, although already turned green with heavy rains that arrived early in this year, this rangeland remains virtually empty of cattle. It is, rather, full of sheep and goats. Kitengela's Maasai herders have driven all their cattle southeast to Emali. Said and ILRI Maasai partner Nickson ole Parmisa say that the herders will bring their cattle back home, to Kitengela, in another few weeks, when the grass in Kitengela, which is now new and short, has grown taller. Here is a case study in how Africa's pastoral societies continue to work, against all odds, as communities. Late last year, when the impacts of the drought in the Horn of Africa were peaking, Maasai herders from throughout Kenya's Kajiado District descended on Kitengela with their animal herds because they had heard that the Kitengela rangelands had had 'a few showers'. That was true in a few places, but with all the new livestock driven in to this one part of Kajiado, Kitengela was reduced to a dustbowl within a few days. With no forage to eat, the livestock of Kitengela perished soon after the stock that had been trekked in from far places. Many people began to question the wisdom of traditional pastoral movement on Africa's increasingly fragmented rangelands. Now, just a few months later, the Maasai herders of Emali are returning the hospitality, and mercy, shown them last year by their Kitengela cousins. It is now the Emali Maasai who are sharing their green grass (the rains came earlier to Emali than to Kitengela, so the grass at Emali is taller than that in Kitengela) with the hungry animals of Kitengela. While scientists at ILRI and elsewhere debate the wisdom of pastoral mobility (does it still work in today's crowded world?), what apparently is not in doubt is the wisdom of pastoral reciprocity.

Moving from project mode to innovations systems thinking?

Reflecting on some ILRI experiences in Ethiopia, Alan Duncan explores some challenges associated with innovation systems approaches that focus less on promoting a specific technical solution and more on facilitation of innovation, learning and joint actions among groups of people and organizations. He poses two important generic questions:

  • facilitating stakeholder platforms is quite demanding of time and resources in itself. Is the use of stakeholder platforms just another project-led approach? Who will take responsibility for facilitating these platforms when we are gone?
  • Is our focus on planted fodder and improving feed supply for production of livestock commodities untenable in a food insecure area?

Livestock emissions and livestock systems in developing countries

According to Carlos Seré, Director General of ILRI, the livelihoods of a billion people, particularly in Africa and Asia, are attached to livestock – and consequently to their greenhouse gas emissions. If livestock are removed, many of these people have few other livelihood opportunities. He argues: "improving feeding is one of the key interventions to improve the efficiency of livestock systems, i.e. to produce less methane per kilo of output" – which will relieve pressure on other natural resources like forests. He cautions that aggregating livestock emissions globally misses the big differences between developed and developing countries. It is important to separate the two. "To design policies you really need to clearly separate the problem." In developed countries, livestock production is mainly commercial and there are a number of policies and instruments that can be applied to reduce livestock emissions. In poor countries as well, he states, livestock emissions can be reduced – "but we need to be aware of the stark trade off. We may end up with lots more poor people and hungry children."

Putting livestock on the climate change table

New options should focus on helping hungry animals and people adapt to climate change while mitigating the greenhouse gas emissions of small-scale livestock production systems.

Farm animals have been providing the world with an uncommon array of benefits since before the dawn of agriculture. Indeed, most small-scale farming even today would be impossible without them. But it is the world’s poorest people—some one billion of them—who depend on cattle, sheep, goats, chickens and other domestic animals the most. Livestock keeping helps them sustain their herding cultures or small-scale farming (e.g., animal manure fertilizes croplands; cattle and buffalo pull ploughs and transport farm produce to markets). Livestock provide them with a rare means of earning and saving an income (people can sell milk, eggs, manure or surplus stock, or they can find jobs in dairy or related businesses). Livestock foods feed hungry people (families can consume the milk, meat and eggs their stock produce or sell these high-quality foods to buy cheaper starchy foods). And livestock are a last hedge to protect households against the shocks common to the rural poor—from drought, flood or disease that destroys food crops in the field, to market distortions that make farm produce worthless, to civil unrest that makes people flee their homes, and, finally now, to a warmer world with increasingly unpredictable weather and extreme weather events.

But the inexorable rise of human populations, along with the aspirations and appetites of their growing middle classes, have led also to global livestock populations of increasing numbers and increasingly intensive livestock production practices. While overconsumption of red meat and other livestock foods is damaging the health of many people of the North, under-consumption of these nourishing foods is hurting, and killing, many people of the South. In terms of the environment, livestock production globally causes up to 18% of the human-generated greenhouse gases that are warming our planet. Livestock do this both directly (methane, for example, is produced in the rumination processes of cud-chewing animals) and indirectly (such as the felling of forests to make room for fodder crops and ranching). The factory farms of industrialized countries not only can treat animals inhumanely but also can pollute air and water and threaten human as well as animal health. The herding and farming families of developing countries, on the other hand, typically maintain their ruminant animals on poor-quality feeds that make conversion of feed to milk and meat inefficient and environmentally damaging—skinny ruminants on poor diets, while not competing with people for grain, produce much more methane per unit of livestock product than do well-fed cattle, sheep and goats.

Just one hundred years ago, the principles and practices of animal husbandry were pretty similar across all the regions of the world where it was practiced (which pretty much meant all the regions of the world). But as schisms have opened up between the livestock production systems and peoples of today’s rich and poor worlds, we must now start from a new understanding—an understanding based on decades of livestock and systems research—that ‘local context’ is everything.

In the North, we need to focus on mitigating the impacts of livestock production and consumption on climate change. We already have many workable and alternative ways of reducing greenhouse gas emissions and the environmental and health ‘bads’ of intensive livestock production systems. We need to get them implemented and to begin monitoring our reductions in livestock-produced greenhouse gases as we begin to build more sustainable and healthy food systems.

In the South, where most of the world’s poor live, work and are fed by hundreds of millions of small-scale farmers and herders, the impacts of climate change will be greatest—and typically experienced at first hand. These farmers and herders include the largely rainfed crop-and-livestock farming communities that, unknown to many, have become the world’s biggest source of staple foods for the poor as well as many of the world’s most renowned herding cultures.

In the rural South, there are few ways of making a living other than by producing food from the land. Therefore, while we need to encourage people to mitigate the greenhouse gas emissions generated by their livestock enterprises, we need to focus most urgently on helping these people and communities to adapt their production systems to climate change. New incentives and technology and policy instruments should allow them to continue to provide the foods, jobs, livelihoods and environmental services that their livestock make possible and doing so in increasingly more efficient and sustainable ways.

With a perfect storm of food, water and energy shortages fast approaching—and 1 billion livestock livelihoods at the very centre of a nexus of human, climate and environmental vulnerabilities—the time for helping developing countries and communities to transform their livestock sectors has come.

As we move further into a 21st century characterized by depleted natural resources and the projected ‘human tsunami’ that is expected to peak by mid-century with a population of more than 9 billion, those of us in research for development need to focus our energy and attention on the little- as well as well-known levers that drive big change.

Across the developing regions of Africa, Asia and Latin America, the raising and selling of farm animals, and the increasing consumption of milk, meat and eggs, together represent one of those ‘big-change’ levers. The ubiquitous small-scale livestock enterprises found in every country of the developing world can represent pathways out of poverty and hunger. They can also promote climate change. Livestock researchers are acutely aware that they are working at these critically important crossroads.

Promising technologies not enough on their own to bring about widespread change in livestock systems

In this short video, ILRI’s Alan Duncan introduces the IFAD-funded ‘Fodder Adoption Project’ based at ILRI.

He outlines the approach followed in the project – trying to strike a balance between the technological and institutional angles.

The project helps groups of stakeholders – farmers, private sector, dairy coops, the government – get together in ‘innovation platforms’ where they can develop joint actions that address livestock fodder problems.

Initially the project went with a traditional approach, focusing on technologies. As the process evolved, other issues came in, more actors joined the platforms, and the technologies – growing improved fodder – acted more as a catalyst for people to come together to discuss a wide range of other issues (dairying, health, etc).

Fodder proved to be a useful ‘engine’ for the group to identify a much wider range of issues to address – along the whole value chain.

He explains that this type of work facilitating stakeholder platforms is “not trivial.” But it is essential: “Technology is only one small part of the equation and really a lot of it is about human interactions and how organizations behave.”

He concludes: “We have lots of promising technologies, but in themselves they are not enough to bring about widespread change in livestock systems.”

Innovation network platforms to overcome fodder scarcity

In this short video, Ranjitha Puskur from ILRI shares some lessons emerging from the DFID-funded Fodder Innovation Project.

The project looks at fodder scarcity and how to address it, but from the perspectives of capacities, policies and institutions.

This current second phase of the project, she says, emerged from the realisation that the availability of technologies is not really the limiting factor, policy and institutional factors are the major bottlenecks.

She briefly introduces the innovation systems approach that underpins the project: Essentially, the aim is to form and facilitate a network of different actors in a chain or continuum of knowledge production and its use, mobilizing all their various resources and capacities to address a problem.

What outcomes and changes has she seen?

At the farm level, farmers are changing their livestock feeding and management practices; there is an emerging demand for technologies, inputs and services that, ironically, were earlier promoted without success.

“Farmers are seeing the need for knowledge and can articulate demands to service providers.”

She emphasizes that “getting a network of actors isn’t an easy process, it takes time”. Different organizations with different interests and motives have to be brought around the table to contribute and benefit.

“It needs great facilitation skills and negotiating skills which are not very often core competences of researchers like us.”

Beyond facilitation of this network formation, “we also see that linkages don’t happen automatically” … we need a facilitating or broker organisation to create them.

In her project, they work through key partner organisations: “This works well, but they needed much support and mentoring from us.”

She concludes with two final observations: Policies are a very critical factor and it is important to engage policy makers from the outset, ensuring that we know what they really want, and that the evidence base is solid.

Traditional project management approaches don’t seem to work in such projects: We need nimble financial management, and very responsive project management.

“Very traditional logframes and M&E systems seem very inadequate.”

Improving the performance of crop-livestock systems

Last week, the CGIAR System-wide Livestock Programme (SLP) held its annual planning meeting in Addis Ababa.

In this short video, John McDermott, ILRI Deputy Director General for Research introduces the SLP. He argues that its focus on the intensification of crop-livestock systems is critical: More than a billion people in developing countries are involved in these smallholder systems.

The SLP brings together 12 CGIAR centers, and, he mentions, “one of the key things we’ve been struggling with is how to improve the performance of these [crop-livestock] systems” – so people can get more income and more benefits from them; also so the systems can be more sustainable.

Reflecting on the just-completed SLP meeting in Addis Ababa, he highlights one of the major issues under discussion: how the crop biomass from these systems can be used more effectively – as food, as animal feed, and as fuel. Furthermore, how the crop residues can be fed back into the soil.

“Now we are turning our attention more to this tradeoff between whether you actually feed these residues to animals or whether some of them should stay with the soil.”

Feeding livestock, sustaining soils: Crop-livestock tradeoffs focus of SLP discussions

This week, ILRI Addis Ababa hosted a meeting of the Livestock Programme Group that steers the CGIAR’s Systemwide Livestock Programme (SLP). The Programme builds synergies between crop research and livestock research across the CGIAR.

A major discussion point at the meeting is the “pressure on biomass use in systems.”

Bruno Gerard, SLP Coordinator, explains that the group will look especially at tradeoffs in the use of crop residues – between feeding livestock or sustaining soils.
