AT A GLANCE!! - Science Forum 2013

"Agricultural research and nutrition go hand in hand with regards to food security." This was the opening remark for the Science Forum 2013. With that, key factors in research regarding major crops like maize and rice, and the requirement of genetic research, need to be put in place. The innovative transfers of research findings is very essential especially to the farm levels; through networking and partnership, exchange is promoted among international agricultural centres, institutes and scientists.

Funding bodies allocate funds for agricultural research institution in partner countries, with the role for its member organizations being to support European agricultural research and development to promote knowledge transfers. This would contribute to success of international agriculture research for development. System level-objectives of these funding bodies include reformation which focuses on reducing rural poverty, improving food security in terms of quantity, quality and affordability, improving nutrition and health, and a sustainable management of environment and natural resources.

Food for Thought: Do Agricultural Innovations Improve Our Health?

The Science Forum 2013 in Bonn, Germany, Discusses the Links between Agriculture and Health and how they can be Improved

Imagine for a moment that you're a small-scale farmer from a poor region and you grow a number of crops. Some of the crops you sell for cash which you probably use to purchase other foods you don't grow yourself, or to pay for other family expenses. The food you don't sell, you eat. But you later decide to start growing a high-yielding cotton variety with a good market demand. Your new choice in crop brings you greater income which you then use to purchase a wider range of healthier, more nutritious foods that you may not have had access to before. Such a scenario makes sense, unless you consider the contradicting evidence currently coming from research in China. (read more)

Facts and Figures: Did you know that cooking loses the beta carotene in food?

The study conducted by Inge Brouwer of Wageningen University confirms that beta carotene retention in raw food is higher than in cooked food. She took the example of sukuma wiki, a wild plant that is native in Kenya. During 28 hours of storage, the Beta carotene content of cooked sukuma wiki decreases from about 2.8 mg/100g to 1.6, while in raw food it slows down from 3.5 mg/100g to 2.1. One of the knowledge gaps she raised is how food composition tables especially for processed food can be improved.

This study of sukuma wiki came about with the question of “Can local diets fulfill all nutrient requirements?” This is under the assumption that diet diversity, using locally available, acceptable and affordable food, can fulfill the energy and micro-nutrient needs of people. She concluded that apart from sukuma wiki which is already explored, improvement of diets with locally available food may not fulfill all the nutrient requirements such as iron, calcium and zinc. She cautioned that more information is needed before promoting them.

Agroforestry and fruit diversity enhance food and nutrition security

During the first day of the Science Forum, we have 2 sessions of “knowledge share fair” for scientists to present and discuss their studies in digital format and a cozy setting with morning coffee and hot buns served. When I came into the room, there were already a few people crowded in front of a “poster”. Katja Kehlenbeck works for ICRAF- Would Agroforestry Centre in their Nairobi office in Kenya, and she was telling us how their newly developed model “Fruit tree portfolios” can identify local specific fruit tree sets, which help the Kenyan farmers to reintroduce fruit trees into their farms according to seedling availability and seasons.

NSA at Tropentag 2013

The oral presentation session “Food consumption, consumer preference and human health” hold rich reminders why agricultural research should not only focus on food production, but always need to keep an eye on the consumption side. Under the order of NSA, Hannah Jaenicke presented a holistic framework on how to narrow the gap between the already quantitatively sufficient supply of nutrients and a qualitatively balanced diet. Even though, this does not relate to the latest scandals from the US, her transatlantic observations for example included the fact even within one household some members are obese while others are undernourished.

The motion for lunch is rejected

‘The motion for lunch is rejected’, ruled Joachim Von Braun of the University of Bonn wittily, when chairing the first plenary session at the Science Forum 2013. He rather carried on with the session, setting the scene of the Forum and pointing out, why sufficient lunch is also still rejected to 925 million people world wide. To answer why 15% of the world’s population suffer from undernourishment after decades of agricultural research is indeed a tough one. The vast amount of knowledge gathered during this time was obviously not enough. At the same time ‘We don’t need to know everything’, Von Braun pointed out. What we really have to know, keynote speaker Patrick Webb from Tufts University sketched - to provide everybody with the lunch they deserve.

“Strict” Border Restrictions are not enough to curb Pests and Diseases!!
Insane as it sounds, that is the reality of things.

Pests and Diseases management has been part of scientific discussions since time immemorial with regard to agricultural production systems. With this year’s conference theme, “Agricultural development within the rural-urban continuum”, pest and diseases was not left behind, and this brought great discussion among scientist from all over the globe.

Amazing interactions between plant viruses, their vectors and their hosts plants was reported by Stephan Winter, a virologist from Leibniz-Institute, Braunschweig, Germany. According to Winter, plant viruses can travel long distance as far as United State from Africa, to Europe. This has been made possible by international trade of planting materials, vegetables and cut flowers, enabling pests and diseases of economic importance to cross strict boarders.
Generally, several driving factors have been found to contribute to this menace, scientist are committed to find solutions for the control and containment of pests and diseases.These include, cultural measures, biological control of the pest, use of tolerant crop varieties against plant diseases among others.

No stress! How overwhelming conservational concerns can harm socio-economic factor.

OP2 Syabilla_Rivenia

In the oral presentation session Resources within the Rural-Urban Continuum number of researchers prove that overwhelming concern about natural area and biodiversity protection can cause economic and social problems: agroforestry in Indonesia is more beneficial, than solely forest; use of wetlands for crop production in East Africa does not harm plant diversity; partial replacement of mangrove forest in Myanmar with rice farms is economically more viable, than forest alone; pastures in Caucasus Region are prioritized higher, than National Parks. see more
