Selecting forages for the tropics with the the SoFT tool

Thus, the need for information on forages for specific climates, soil types, farming systems, and animals is enormously important to mitigate feed shortages and improve natural resource management.

Established in 2005, the selection of Forages for the Tropics (SoFT) tool enables users to identify forage species suitable for specific climates, soils, and farming systems such as cut and carry, agroforestry, erosion control, beef, and dairy. Users can also view images of the plants and their use, search a database of scientific references with abstracts, and consult a glossary of botanical and management terms.

Livestock and livelihoods: boosting incomes and productivity in South Asia

Livestock provides an important complement to cereal farming-based livelihoods in South Asia and can increase incomes for millions of crop-livestock farmers.

With other Cereal Systems Initiative for South Asia (CSISA) partners, the International Livestock Research Institute (ILRI) has been helping crop-livestock farmers to boost income and milk production by increasing the availability of fodder, promoting efficient use of cereal residues and improving the quality of supplementary feeds in India, Bangladesh and Nepal.

What’s the beef? Giving livestock a break in Colombia

Cows are regularly portrayed as evil: four-legged, four-stomached, greenhouse gas machines chomping through forests and destroying the planet.

It’s no wonder the idea of a climate-smart livestock system sounds like an oxymoron.

Nevertheless, you can get a glimpse of these systems in Colombia’s mountainous, Cauca Department. Patía is also a microcosm of Colombia’s livestock conundrum. With around 23 million beasts, the country has as many cattle as Australia has people, grazing an area the size of Germany. At an average of one animal to 1.4 hectares, it’s lot of land for not much cow.

It’s also the recipe for environmental calamity. Land degradation due to livestock production is widespread, forests have been cut down to make way for new grazing areas, and livestock are responsible for nearly all of the country’s agricultural greenhouse gas emissions.

But somewhere like Patía, there are few other options.

Prioritizing climate-smart livestock interventions in Africa

Around the world, there is a pressing need for wide-scale innovation leading to development that improves the livelihoods and food security of the world’s population while at the same time addressing climate change adaptation and mitigation. While there are various promising climate-smart interventions, prioritizing them is a challenge.

In this paper, the authors provide a generic framework for evaluating and prioritizing potential interventions comprising the mapping of recommendation domains, assessing adoption potential and estimating impacts. Through examples related to livestock production in sub-Saharan Africa, they demonstrate each of the steps and how they are interlinked. The framework is applicable in many different forms, scales and settings. It has a wide applicability in planning for climate-smart agriculture, which invariably involves multi-stakeholder, multi-scale and multi-objective decision-making.

Effects of White Spot Disease and biosecurity on shrimp farming in Bangladesh

Shrimp culture is of central importance in Bangladesh, shrimp being the cash component of many smallholder, polyculture fish farming systems. Shrimp also contributes substantial income through exports. However, production remains low compared with other countries for a number of reasons, including low availability of good quality post larvae (PL) seed stock, lack of credit facilities, and disease problems.

Ensuring access to white spot syndrome virus (WSSV) free PL combined with the implementation of best management practices at farm level will help reduce disease risk and stimulate investment, leading to improved shrimp production and improved farmer livelihoods, as argued in this paper by the WorldFish aquaculture science team in Bangladesh.

Towards a toolkit to analyse livestock and fish value chains

The CGIAR Research Program on Livestock and Fish has been operational since January 2012. It seeks to improve the diets of poor people for healthy productive lives, and sustainably increase the productivity of small and medium-scale livestock and fish producers for food secure futures.

The program has implemented several approaches across different sites in nine countries, including in-depth analysis of livestock and fish value chains. Among the approaches is use of tools designed and developed to systematically collect information from different actors at different levels in the value chains. Over the past five years, several tools for value chain assessment have been produced, covering different aspects of assessment including gender issues.

 Note card

Livestock and Fish value chains are unique and have distinct features. For instance, the products, such as milk and meat, are of higher value and in some cases are bulky and highly perishable. Also, delivery of some inputs and services such as animal health service is costly. In addition, at the livestock keepers’ level, livestock are predominantly multi-functional, often kept not only to produce milk or meat for home consumption and sale, but also to produce manure for fertilizing croplands, to pull ploughs and are also considered a major capital assets. For this reason, livestock keepers’ decisions in terms of type and level of participation in a value chain is influenced by many factors.

The uniqueness of the livestock and fish value chains compared to other value chains makes it paramount for researchers and development practitioners to use highly targeted tools, specialized and tailored to guide research and development interventions.

While all the value chain assessment tools developed and used in the course of the Livestock and Fish program implementation have been availed in an online working space, there was a need to document, organize and describe how to use these tools.

From 18–20 May 2016, a small group of researchers from the International livestock Research Institute (ILRI) and WorldFish working in the Livestock and Fish program participated in a writeshop to consolidate all the different value chain tools produced and used over the past four years into one comprehensive value chain analysis toolkit.

The objective is to produce a well-organized set of tools that can be used to identify ‘best bet’ interventions that improve the effectiveness, efficiency and inclusiveness of livestock and fish value chains – that can be adopted by other practitioners in agricultural research for development.

The writeshop was preceded by a survey to identify their experiences of the users currently using these tools including information on how they are mostly used and suggestions for improvement. Among other suggestions, most users asked for a short, succinct toolkit that is easier to use, to increase chances of its adoption.

The toolkit will detail four main implementation stages to follow when carrying out analysis of livestock and fish value chains, moving from tools for broad characterization at national level to more detailed and focused tools. The tools in the last stage will include information on ‘best bet’ monitoring, evaluation and learning.

Assessing chemical and biological product use in aquaculture in Bangladesh

An assessment was made of the current chemical use practices in the aquaculture sector of Bangladesh and the factors that influence them.

The study shows that, despite rapid expansion of commercial aquaculture in Bangladesh, use of chemical and biological products is still relatively low compared to other aquaculture producing countries in Asia.

However, despite this finding, the study identified a large number of compounds that are currently in use, and that require further regulation and evaluation regarding their potential environmental and human health impacts, as already done in most developed countries.

Dairy platform tackles sector problems in Tanzania’s Tanga region

The Tanga Dairy Platform, created in 2008, is an informal forum of different stakeholders involved in the dairy industry of Tanzania’s Northeastern Tanga region. The platform’s objective is to exchange knowledge and develop joint actions to common problems.

According to the authors of this article, it is now a sustainable example of a commodity association addressing the joint problems of the region’s dairy industry. The platform has achieved a common understanding among chain actors on dairy price structure; it has successfully lobbied policy makers to reduce value-added tax on dairy inputs and products, and to remove limitations on urban dairy farming in Tanga city.

Tanzania Dairy Board communication workshop participants.

The Tanzania Dairy board (TDB) and partners recently reviewed progress in communicating the activities of the Dairy Development Forum (DDF) across the country.

In a communication review workshop held in Dar es Salaam on 28-29 March 2016, 16 staff and partners of the TDB, expressed the need to revamp TDB’s communication strategy following a strengths, weaknesses, opportunities and threats (SWOT) analysis, and agreed on an action plan to guide implementation of TDB communication activities in the coming year.

The action plan will address among other priorities increasing capacity for resource mobilization, and creating a robust database for an information management system.

The Dairy Development Forum (DDF) is the national platform where value chain actors including producers, traders, input suppliers, extension workers, service providers and processors meet annually to network, exchange information, discuss problems facing the sector, and come up with solutions to those problems.

TDB is the secretariat of the DDF and in this role coordinates the platform, which was set up with the support of the Irish Aid-funded MoreMilkiT project that is being led by ILRI in the country. Improving communications among DDF members is considered crucial to the realization of a vibrant dairy sector and attracting more investments to transform it as envisaged in the Maziwa Zaidi Theory of Change. TDB now pays the main role in efforts to strengthen the DDF and this is expected to continue after the end of the MoreMilkiT project. . The DDF has provided TDB with additional ammunition to mobilize, coordinate and promote the dairy sector in line with TDB’s statutory role in the Dairy Industry Act of Tanzania . The MoreMilkiT project is also working with other partners including Heifer International, Sokoine University of Agriculture and Faida MaLi to test interventions aimed at promoting commercialization of dairying among marginalized cattle producers in Tanga and Morogoro.

Some of the key outputs discussed at the meeting were a new TDB website which will include information on the Dairy Development Forum (DDF), a resource mobilization strategy to guide fundraising activities of the board and a dairy value chain partners’ information database that will be set up in the second half of 2016.

The meeting was facilitated by the International Livestock Research Institute (ILRI) and was attended by representatives from Tanzania Milk Processors’ Association (TAMPA), Heifer International and Tanzania Milk Producers Association (TAMPRODA).

This was a follow up to an earlier workshop in May 2014.

Review of sheep crossbreeding in Ethiopia

The objective of this paper is to examine whether or not sheep crossbreeding is a feasible option to improve indigenous sheep breeds in developing countries using Ethiopian case as example.

The paper reviewed and discussed the history of exotic breed introduction, research, and development efforts in crossbreeding and performance of crossbreds under on-station and on-farm management.

Earlier, in Ethiopia, the choice of breed for crossbreeding overlooked interests and preferences of farmers mainly for physical appearance. More recently the introduction of Awassi sheep considered their preference. Performance evaluation results from the on-station and on-farm (mainly based on Awassi pilot crossbreeding villages) showed that crossbreds often outperformed their local contemporaries. Thus comparisons of pure local sheep and crossbreds among those breeds produced in some areas indicated a good outcome of this type of crossbreeding. However, the performance of crossbred sheep varied by location and depended on management and exotic inheritance levels. For most programs, no comprehensive data were available to do on-farm comparisons of herd productivity and cost-benefits or to evaluate the sustainability of the programs.

Regardless of location, farmers participating in crossbreeding often showed keen interest in crossbreeding, mainly due to the fast growth, larger body size of crossbreds resulting in higher market prices as compared to their local sheep breeds. Ram multiplication and dissemination from the government farms were found inefficient. The predominant practice of a ubiquitous dissemination and selling of breeding rams to individual farmer dilute the efforts of crossbreeding and prevents generating the benefits expected from crossbreeding programs. Furthermore, indiscriminate crossbreeding without prior analysis of suitability of crossbreds for a given production environment and without clear breeding objectives presents a potential threat to better adapted indigenous breeds.

Crossbreeding programs require strong research and development support from public service and non-governmental institutions for sustainable design, optimization, and implementation in clearly defined production environments.

WorldFish aquaculture project increased profitability of farms in Eypt

The Swiss Agency for Development and Cooperation (SDC)-funded Improving Employment and Income through Development of Egypt’s Aquaculture Sector (IEIDEAS) project was implemented by WorldFish in partnership with CARE Egypt and the Egyptian Ministry of Agriculture and Land Reclamation from 2011 to 2014 and later extended to November 2015.

In 2015, the project team focused on assessing the quantitative impacts of the IEIDEAS project through three field-based surveys: a best management practice adoption survey to determine whether fish farmers had applied the recommended practices, a fish farm and farmer impact assessment survey, and a retailer survey to assess the degree to which project-assisted retailers had benefitted.

The project resulted in greatly increased profitability for fish farms (equivalent to around USD 16,000 in extra profit generated per farm, USD 27 million total value added by the project). Increased profitability was mainly achieved by cost savings through more efficient feed management rather than increased production. This will result in reduced environmental impacts (greenhouse gas emissions and nutrient discharges). However, the directly attributable increase in fish production was only 200 metric tons (t) per year. Earlier studies had established that 14 fulltime equivalent (FTE) jobs are created along the aquaculture value chain for each 100 t per year of production, suggesting that only 28 FTE had been added by the project by the end of 2014. Clearly, this fell well short of the target of 10,000 jobs. However, this target is likely to be met as a result of project interventions as the use of the Abbassa strain expands and farmers invest their profits from improved practices in intensification of production.

The work with women retailers has increased understanding of this vulnerable group and led to the development of a toolkit of approaches that could be scaled out to other communities. The main benefit achieved appears to have been the empowerment that they gained from being able to work together in a group and advocate for their rights with local authorities and other value chain actors, such as wholesalers.

The IEIDEAS project has resulted in a follow-up project, also supported by SDC and managed by WorldFish in collaboration with CARE and the Ministry of Agriculture and Land Reclamation. The 3-year Sustainable Transformation of Egypt’s Aquaculture Market System (STREAMS) project started in December 2015.

Livestock and fish gender writeshop – first reflections

Writeshop participants

Last month, a Livestock and Fish gender integration writeshop pulled together the learning and experiences from 14 gender integrated technical, systems and value chain research projects from across the CGIAR Research Program on Livestock and Fish.

A team from the Royal Tropical Institute (KIT) facilitated the process and will finalize the book, which is expected mid-September 2016. Here are three points of reflection from the KIT team.

1. “Everything Should Be Made as Simple as Possible, But Not Simpler” (Einstein)

Every field of science has its particular language and jargon – not only gender, but also genetics, health, feeds and forage, value chains and systems research. Finding the right language and making complexity understandable to an intelligent but not necessarily expert reader entails navigating across the various disciplines and asking a lot of questions. This book on gender integration in the CRP Livestock and Fish aims for an accessible style but the challenge is how to simplify language while maintaining nuances that matter. The process of writing in a simplified style stimulated scientists to think differently about their work, articulating findings more sharply, being concrete about their relevance, cutting out some of the ‘scientific fluff’ (jargon) from initial write-ups and deepening their processing of data. The writeshop allowed a round of iteration, reflection, analysis and insight building for 14 projects, most of which have been coached on gender integration since mid-2015.

2. Spectrum of depth of gender analysis, gender integration and gendered findings

The gender-integrated research projects presented exhibit a spectrum of depth vis a vis gender analysis and integration: from basic sex-disaggregated data collection and analysis of what is similar or different in what men and women say, do and know; to gendered research questions and embedded gender concepts. The depth of gender integration depends in part on the kind of problem that the research seeks to unravel. Michel Dione and his team found that the gender division of labor in pig management in Uganda was quite static during normal routines, but when an African Swine Fever outbreak struck, gendered task divisions broke down and both men and women did everything in their power to manage the outbreak. This lead the team to conclude that training and protocols on African Swine Fever needed to include both women and men in order to be effective. Another project written up by Nicholas Ndiwa developed a framework for developing good indicators, data aggregation and smart analysis to support scientists in implementing and designing and analyzing gender data. A third project looked at the ‘silent breeders’ – women – in dual purpose cattle systems in Nicaragua. Alejandra Mora and Julie Ojango explored the reasons behind women’s silence in the breeding sphere and the cost of that silence both socially and in terms of improved genetic outcomes. They conclude with insights as to how research can influence the ‘sound of silence’ by engaging better with these women breeders who play critical roles in genetic decision-making.

3. Gender integration is an ongoing process

Unsurprisingly, 8 months of gender integration coaching will not transform a non-gender scientist into a gender expert. However, learning does happen and a deepening of understanding and shared language begin to emerge on interdisciplinary teams. What a non-gender scientist can do on their own and where gender expertise is required depends very much on the individuals involved. A clear next step in the process for many of these projects is more in-depth data analysis. Some non-gender scientists need more support than others on this, depending on their capacity and whether there are gender scientists/specialists already on the team. Integrating gender into technical, value chains and systems research is an ongoing process that builds up the collective capacity of the research program to do interdisciplinary, gender-integrated research better.

What’s next?

The book will be published in mid-September and will be available both online and in hard copy. KIT will continue to support the coached projects in preparing peer-reviewed publications, possibly including a special issue in a related journal. In the meantime, the findings from the research projects and the gender integration process are being woven into the phase 2 plan and proposal for the new CGIAR research programs on Fish and on Livestock. This foundation of consolidated thinking and research will serve both new CRPs from 2017 as they continue to embed gender into their programs and theories of change.

WorldFish and partners project on sustainable transformation of Egypt’s aquaculture market system

The Sustainable Transformation of Egypt’s Aquaculture Market System (STREAMS) project aims to increase production of inexpensive, nutritious and safe fish from sustainable aquaculture systems to help improve the health and nutrition of Egypt’s resource-poor while creating employment and increasing incomes along the aquaculture value chain.

Launched in February 2016, STREAMS will increase the participation of Egypt’s underprivileged socioeconomic segments in the country’s fast-growing aquaculture sector while also making fish more affordable and accessible. Increased availability and consumption of fish can reduce Egypt’s high rates of childhood stunting, undernutrition and obesity.

Download the project brochure

STREAMS is funded by the Swiss government. It builds on the significant gains realized in sustainably transforming Egypt’s aquaculture market system through the Improving Employment and Incomes through the Development of Egypt’s Aquaculture Sector (IEIDEAS) project. It is managed and led by WorldFish and implemented by CARE and the Ministry of Agriculture and Land Reclamation.

A meta-analysis of Contagious Caprine Pleuropneumonia (CCPP) in Ethiopia

This systematic literature review was initiated due to lack of comprehensive information on the status and distribution of contagious caprine pleuropneumonia (CCPP) in Ethiopia.

The objectives of the review were thus to provide a pooled prevalence estimate of CCPP in the country and asses the level of in between study variance among the available reports.

To this end manual and electronic search was conducted between 8th of January and 25th of June 2015. A total of twelve published articles and one MSc thesis was retrieved from19 initially identified studies. Twenty five animal level datasets were extracted at regional level considering some hypothesized predictors. The retrieved data were summarized in a meta-analytical approach. Accordingly, the pooled prevalence estimate of CCPP was 25.7% (95% CI:20.9,31.0).The inverse variance square (I2) that explains the variation in effect size attributed to reports true heterogeneity was 95.7%.The sub-group analysis was also computed for assumed predictors including, age, sex, type of study population, production systems and regional states. Among these predictors, study population type revealed statistically significant difference (P < 0.05). Accordingly, the prevalence estimate for samples collected at abattoir was 39.2%, while that of samples collected at field level was 22.4%. In the final model, type of study population fitted the multivariable meta-regression model accounting for 22.87% of the explainable proportion of heterogeneity among the presumed predictors.

Evidence on isolation and confirmation of Mycoplasma capricolum sub spp capripneumonie in the country was obtained from five regional states.

In conclusion, it is recommended to further investigate facilities related with transportation and collection premises along with potential role of sheep in the epidemiology of CCPP. Finally, the review emphasizes the need for monitoring the ongoing CCPP control intervention and introduces amendments based on the findings. Besides more surveys are needed in some of the regions where no or few valid data was available.

Multidimensional crop improvement research on grain legumes in Ethiopia

The Livestock and Fish program joined the Africa RISING project in supporting these theses.

Africa RISING

Three Ethiopian MSc. students, who contributed to ICARDA’s research on multidimensional improvement of grain legumes recently graduated from Ethiopian Universities. Tena Alemu and Asemahegn Mersha graduated from Hawassa University under joint supervision of Jane Wamatu (ICARDA), Adugna Tolera and Mohammed Beyan. Teklu Wegi graduated from Haramaya University under joint supervision of Jane Wamatu, Adugna Tolera and Getachew Animut. The USAID-funded Africa RISING project and the Livestock and Fish CGIAR program jointly supported Tena and Asemahegn while Teklu was entirely supported by Africa RISING.

The students have unlocked key trends and trait relationships across grain legume crops that can inform and further guide crop improvement.

Asemahegn MershaAsemahegn, who evaluated the cultivar-dependent variation in food-feed traits in lentil (Lens culinaris), determined that there are significant genotypic and location variations for grain yield and straw traits in lentil and GL has significant effects. Correlations between grain and straw yields are positive, moderate…

Ultrasound pregnancy diagnosis as low-tech tool to enhance small ruminant production

Productivity and profitability of meat and milk production from small ruminants are geared by reproductive performance. Females that fail to reproduce are only negatively impacting the environment. A major setback here is infertility but other reproductive-related problems are also important. A whole generation of easy-use, high resolution, portable ultrasound machines is now available to provide different levels of information which will translate into concrete management strategies. ICARDA has been testing field solutions for ultrasound pregnancy diagnosis to reduce reproductive losses and increase lambing rates in sheep and goat flocks – initially in with Awassi sheep in agro-pastoral systems of Jordan, Karakul sheep in Aral Sea, Angora goats in Fergana Valley and Menz sheep in Ethiopian highlands.

Do smallholder, mixed crop-livestock livelihoods encourage sustainable agricultural practices?

As calls for bolstering ecosystem services from croplands have grown more insistent during the past two decades, the search for ways to foster these agriculture-sustaining services has become more urgent.

The authors examine by means of a meta-analysis the argument that small-scale, mixed crop-livestock farming, a common livelihood among poor rural peoples, leads to environmentally sustainable agricultural practices.

As predicted, mixed crop-livestock farms exhibit more sustainable practices, but, contrary to predictions, a small scale of operation does not predict sustainability. Many smallholders on mixed crop-livestock farms use sustainable practices, but other smallholders practice a degrading, input-scarce agriculture. Some large farm operators use soil-conserving, minimum-tillage techniques while other large operators ignore soil-conserving techniques and practice an industrialized, high chemical input agriculture. The strength and pervasiveness of the link in the data between mixed crop-livestock farming and sustainable agricultural practices argues for agricultural policies that promote mixed crop-livestock livelihoods.
