Madrid, 8 de marzo de 2016
El Ministerio de Agricultura, Alimentación y Medio Ambiente (MAGRAMA) ha acogido la presentación del “Año Internacional de las Legumbres 2016” organizada por la Asociación de Legumbristas de España (ALE) y de la que se han sacado dos conclusiones claras: que las legumbres son básicas para conseguir una dieta saludable y que es necesario aumentar su consumo en España ya que estamos cada año más lejos de las recomendaciones de ingesta semanal de este alimento básico para la salud.
El secretario general de Agricultura y Alimentación, Carlos Cabanas, fue el encargado de presentar el acto, agradeciendo a la Asociación de Legumbristas de España la iniciativa de presentar el “Año Internacional de las Legumbres 2016” en el propio MAGRAMA, que lleva mucho tiempo trabajando para concienciar a la sociedad sobre los beneficios de las legumbres, tanto desde la perspectiva alimentaria como de agricultura sostenible. El señor Cabanas apostó claramente por el incremento de la producción y consumo de estos alimentos por su importancia agronómica, medioambiental y nutricional.

What does one bag of beans mean in the global effort to end hunger? It turns out, a lot. 2016 is the International Year of Pulses. It is also the first full year in which we are officially working toward the Sustainable Development Goals, which set an ambitious but attainable target to end hunger by 2030. An important part of this is improving the livelihoods of smallholder farmers – especially women. We have found a way of doing this that also strengthens resilience and improves nutrition: buying more beans and peas.
As the largest humanitarian agency fighting hunger worldwide, the World Food Programme (WFP) reaches an average of 80 million people each year with life-saving food assistance. We also work to eradicate the root causes of hunger; one way we do this is by sourcing our food in ways that build stronger and more inclusive food systems.

Last week, the Pan African Grain Legume and World Cowpea Conference, the first conference dedicated to boosting pulse productivity, nutrition and processing in Africa occurred.
The conference could be a potential milestone in the fight against global hunger as over four hundred academics, NGOs and scientists came together to discuss how pulses could help poor, small holder African farmers to fight climate change, boost productivity and feed their families.
Also last week, a new survey called the ‘Global Pulse Productivity & Sustainability Survey’, highlighted the lack of investment in pulses compared to other crops such as cereals.
To read more about how both the conference and the survey may mark a milestone in the battle to deal with global hunger, try this article in the Huffington Post.

Damage caused by pod borer Maruca vitrata, the most destructive pest of cowpeas, can lead a loss of up to USD 3 billion per year in West Africa alone. To reduce the losses, farmers resort to spraying insecticides, most often inappropriate ones and without protective equipment and gear, thereby exposing themselves and their families to serious health hazards. The damage by the caterpillars of the pod borers can cause up to 80% damage on cowpea farms. Worse, over the years the pod borer has developed resistance to the most common pesticides, and farmers are responding to this by increasing the frequency of pesticide application, thereby exacerbating the problem.
To solve this, researchers of the CGIAR Research Program on Grain Legumes (Grain Legumes) at the International Institute of Tropical Agriculture (IITA) have recently introduced two parasitic wasps (parasitoids), Therophilus javanus and Phanerotoma syleptae, that will act as natural enemies to fight pod borers in cowpeas.
Initially, two rural farmer communities in southern Benin have adopted these new small wasps for sustainably fighting the pod borer. These parasitic wasps will actively search for the target pest in cowpea flowers and pods, and lay eggs inside the caterpillars of the pest, which will hatch and destroy the pest from inside. With these wasps, the smallholder farmers now have a natural, safer, cheaper and environment-friendly ally to fight the pod borer and reduce losses.
The released parasitoids work in synergy by having two different modes of action, one being an ovo-larval parasitoid, and the other one being a sturdier larval parasitoid which can detect the presence of caterpillars of M. vitrata inside flowers and pods of cowpea. The parasitoids were released on patches of wild alternative host for the pod borer, where the pest is feeding and reproducing during the off-season, ready to invade cowpea fields with the onset of the cropping season.
This approach of using natural enemies to reduce the population of a pest is called biological control. It is expected to overcome the over-reliance on chemical pesticides and to break the vicious cycle of pesticide resistance and pest resurgence, by substantially reducing the population of the pod borer both on wild alternative host plants during the off season, and on the target crop, cowpea, during the cropping season.
Data from pre-release studies indicate a high potential for these parasitoids to be able to keep populations of the pod borer under the damaging threshold.
Prior to the releases, farmers were sensitized about the essential features of biological control, and the need to refrain from inappropriate use of chemical pesticides in order to preserve the just-released natural enemies.
The parasitoids are expected to establish on the patches of wild vegetation where they were released, and produce several generations thereby increasing their population size and colonizing neighboring patches where host plants for M. vitrata are present. With the onset of the rainy season and the beginning of the cowpea cropping season, the parasitoids will follow the M. vitrata populations migrating to the cowpea fields. An overall 30-50% reduction in M. vitrata damage is anticipated depending on prevailing local conditions (such as rainfall pattern, planting dates, variety).
Reducing the damage by 50% through biological control will bring a financial gain of USD 1.5 billion, and this without taking into account the savings by reduction in pesticides and related health and environmental costs.
Cowpeas, a highly nutritious pulse containing about 24% protein, and several vitamins and minerals, grow in the semi-arid tropics of Africa, Asia, Europe, United States and Central and South America. About 96% (4.9 million tons) of cowpeas are produced in Sub-Saharan Africa alone.
This effort is part of an overall Integrated Pest Management (IPM) strategy for controlling cowpea pests which includes the use of resistant varieties and the safe and judicious use of pesticides (which we are planning to substitute with locally-produced bio-pesticides in the longer term), combined with modern ICT approaches to empower low-literacy farmers to make informed decisions about pest control options in close collaboration with Sustainable Animations Without Borders (SAWBO).
This initiative is an ideal example of how international funding and collaborative research support help smallholder farmers in Africa. The two parasitoids were obtained from the World Vegetable Center (AVRDC) in Taiwan through a collaborative project supported by GIZ. With funds from the USAID Feed the Future Legume Innovation Lab for Collaborative Research on Grain Legumes, the parasitoids were mass-reared and lab tested prior to release at IITA-Benin and released by the Benin National Agricultural Research Institute (INRAB); the Directorate for Plant Production in charge of Regulatory Services at the Ministry of Agriculture (DPV/MAEP); the University of Illinois at Urbana-Champaign (UIUC); and Michigan State University (MSU). The releases were carried out as part of the CGIAR Research Program on Grain Legumes, with co-financing from a precision-IPM scoping grant by the Bill & Melinda Gates Foundation.

John Lethlean is a food writer based in Melbourne Australia. Recently, Lethlean reviewed Chef Simon Bryant's new cook book "vegetables, grains & Other Good Stuff" for the Australian, calling it "exceptional". Not only does Chef Simon Bryant's book provide the consumer with an array of delicious recipes, it also shares insight in the benefits of increasing the consumption of plant-based proteins.
Take this passage, for example, from Chef Simon Bryant's page on pulses:
“Like their legume cousins, beans tick many environmental boxes. They are also playing a part in the new dietary frontier of gut health, which many believe can influence a range of health conditions. This is because beans that are soaked, cooked and cooled (and reheated again if you choose) are great source of resistant starch (RS) which has been touted as a superfood for the digestive system.
“RS passes through the small intestine undigested: it is instead broken down in the large intestine and feeds the good bacteria down there. This process produces a fatty acid that not only fuels the body but keeps lower intestinal cells healthy — which in turn may provide protection against cancer. This is huge news, but all you really need to know is that beans are excellent for your health, and full of flavour and substance.”
