Goodbye Prague, hello Berlin!

People from across the world, with diverse backgrounds and from different fields, academics and non-academics alike; very inspiring and informative talks, presentations and posters, and fruitful discussions; a great venue and splendid weather. This was Tropentag 2014 in Prague. The Czech University of Life Sciences Prague hosted this year's International Conference on Research on Food Security, Natural Resource Management and Rural Development. MANY THANKS to the speakers and presentations, the participants and, of course, the organizers of this brilliant event!

You cannot await next year’s Tropentag Conference either? Then don’t forget to note down next year’s venue: 16-18 Sept 2015 in Berlin, Germany. The conference will be held under the theme “Management of Land Use Systems for Enhanced Food Security – Conflicts, Controversies and Resolution”. See you there!

Unfamous last words

The last session has ended, posters and flowers have quickly been taken away: Tropentag 2016 is finally over. It’s been three intense days filled with uncountable posters, lively discussions in public and private, fascinating and more or less mass compatible presentations, music, food and lots of coffee. Even dancing!

Many questions have been asked, but some important ones, I must say, have been left unanswered. “What are the next steps to take?” was one of my favourites, asked by Sara Kaweesa, at the end of the closing session, hoping to get a take home message, something to hold on to, so that this conference could actually help to take a step towards a more sustainable and fair world, and not just have been a gathering of many scientific people wanting to talk extensively about their researches and hoping to make a good impression on certain project funding ministries and donors. As Michael Hauser, who by the way together with Ms. Kaweesa has done an impressive job moderating during this conference, has stated, we’ll need to meet again next year, look back at our work and see if we have been true to our many nice, promising words about sustainability, solidarity, food security, fair distribution of resources etc etc.

Bringing communities together for sustainable and fair use of forestry resources in Chobe, Botswana

Senior Lecturer from the Botswana University of Agriculture and Natural Resources (BUAN), Dr Joyce Lepetu shared her view on tropical forestry in regard to solidarity and fair use of natural resources, main theme of Tropentag 2016.

Toxins in Tropical Food Production

Do you know what rice consumption in Nigeria and milk consumption in Kenya have in common? It’s something that both livestock and crop farmers, especially in developing countries, have to deal with: the risk of exposure to mycotoxins in food. One could hear about this topic today, last day of Tropentag 2016, in the fourth oral presentation about food security and nutrition, as well as yesterday in the third poster session about mobile dryland pastoralism. I had the chance to hear both Olusegun O. Atanda’s and Caroline Makau’s research results about such an issue on food safety, which is considered as a specific problem of tropical regions. Exposure to mycotoxins, in fact, should be as low as possible since these are genotoxic and carcinogenic.

In Kenya, aflatoxins (a type of mycotoxin produced by Aspergillus, a species of fungus) pose a safety risk in cow milk. Research revealed that this resulted from poor feed storage and on field infestation during plant growth, which then contaminated animal feeds and finally ended up in the milk. Caroline Makau stated that especially rotten maize cobs used as ingredients in on-farm formulated feeds caused this problem, and that contamination was especially high in peri-urban farms.

Olusegun Atanda’s study is mainly a call for doing more large-scale research and for stressing the need to continually monitor mycotoxin levels in rice. As it seems, this subject is worth being followed in the future.

Fertilizer or cash? What is the best subsidy and for whom is it?

Why farmers prefer fertilizer over cash? Who are the farmers going for fertilizer, who the ones going for cash?

The study used different sets of choices as possible options to be picked by the farmers. Set A, for example, offered the possibility to choose either 50 dollars or 100kg fertilizer.

The study interviewed 808 households and led to results showing that, in most cases, one's preference would always anyway go for a subsidy, no matter in what form.

Fertilizers or cash?

Result:

And still, the farmer would rather opt for cash depending on the expenses he has. Namely, school fees for children, health insurance, rent.

Implication for policy-makers:

One of the proposed conclusions on the solutions that may improve the support given to farmers focused on the distribution of fertilizer as a subsidy instead of mere money. In the long-term, this could in fact increase the benefits resulting from its usage.

A Practical Handbook for Climate Change Adaption

Seeds of resilients - A novel strategy to discover and use climate-adapted germplasm

Bioversity

At the moment, there are 11 seed banks in developing countries, and they are coordinated by CGIAR centres around the world. Nevertheless, farmers are often still far away from breeding progresses and have no access to diverse, locally adapted seeds. Building up a community driven, decentralized seed banks should be a one of the main priority in future development work.

Bioversity International tries to use crop genetic diversity to face rural challenges and foster adaptation to climate change. This is why a handbook, a resource box for resilient seed systems was compiled in order to assist scientists, plant breeders, farmers and the practitioners in the field. About 150 different stakeholders coming either from the research field or from farms in several countries have worked on this handbook for 3 years..

The strategy presented in the handbook combines climate and crop modelling tools and participatory research methods, and it has 8 steps:

Delivering wind energy to small-scale farmers in Argentina: why did it fail?

Background: in Argentina many areas do not have access to electricity and people are typically practising wood spinning as daily livelihood, apart from farming. In those houses, an EVOLUX G2 500 watt (at 12m/s) electricity plug and light system was installed.

In one of these researched areas, 80% of the systems were not running anymore.

What happened?

small-scale wind energy Technical reasons:

-Broken blades due to the very strong local wind: an inadequate system for this area.

-Batteries ran flat because of no additional power sources

-Other technical breaks: problem arose because efficient over effective systems were chosen

Social/local reasons:

-It was not possible to repair the systems. Spare parts were far away located, young people moved to the cities leading to a lack of knowledge for maintaining and repairing the systems.

-Forbidden maintenance the systems. Farmers as end-users but not as owners.

-Fund of the project did not reach the farmers and the study site. Furthermore, equipment was stolen by farmers who pretended to be government officials.
