Last week i attended a public seminar on GM Contamination in the Durban Botancial gardens organised by BioWatch South Africa. Speakers included; Two agroecology farmers Thombithini Ndwandwe cofounder of the Zimele Rural Empowerment Organisation in MtubaTuba and and Petros Makhanya from KwaNgwanase, Vanessa Black from Biowatch, Ignacio Chapela from the University of California, Berkeley, Rachel Wynberg from the University of Cape Town and SARChI Chair on Bioeconomy and Angelika Hilbeck from ETH Zurich.

Sitting in Cape Town and reflecting on last weeks seminar the theme of drought and seed feels very relevant to write about. Cape Town is currently experiencing The worst drought in recorded history and water supplies are so low that even with severe water restrictions (25 litres per day per person) taps will run dry in April. Cape Towns 4.5 million residents will have to queue for water at 200 water points throughout the city to receive daily rations of water. For months restrictions have meant that watering gardens including food gardens has not been an option. Remarkably however with below average rain for 3 years many plants have managed to survive on the mountain and in gardens. Over the past few weeks i have been noticing tomatoes and rocket shooting up in the cracks in the pavement in our neighbourhood.  These plants have been rapidly growing, and putting out seed in the hope that rain will come soon and some will have the chance of survival. It is amazing to witness the evolutionary resilience of these plant species and how this may be absolutely vital in the future of food.

Angelika Hilbeck’s talk at the seminar, titled ‘The GMO push in Africa and the drought tolerance Trojan horse’ explored drought resistant GMOS and the many of the controversies surrounding this in the African context. Angelika explained how while big promises were made (at the onset of GM crops being released over 20 years ago) concerning the development of new traits and how these would solve world hunger for example, in reality very few genetic innovations have been made.  In terms of maize only two significant traits have been developed, Bt (where GM plants express Bacillus thuringiensis (Bt) toxins throughout their cells which kill stem borer) and Round up Ready ( which are able to withstand Glyphosate herbicide). A further innovation has been to stack these traits so that plants express both Bt and Round up ready characteristics.

However more recently drought resistance has been the focus of genetic engineers. Monsantos DroughtGard contains  the gene for “cold shock protein B” (cspB) from Bacillis subtilis bacteria. While this evolved in baceria to withstand the stress of cold shock it is also intended to help plants survive in similarly water stressed hot conditions.

Drought has been identified as an increasing reality on the African continent in the face of climate change and in 2008 a public-private partnership known as WEMA (Water Efficient Maize for Africa) was established to focus on developing drought resistant maize varieties for the African context. Initially this involved only the development of Hybrid maize varieties and as explained by Angelika Hilbeck was relatively successful in developing hybrids that were more tolerant to water stressed conditions. However in 2015 WEMA’s track changed when Monsanto became a partner organisation. At this point Monsanto donated the insect resistant trait CRY1Ab which was the active trait in MON810. However MON810 was unpopular as insects quickly developed resistance to it. Another addition was the cspB gene first used inMON87460, or ‘Droughtgard’ maize and first commercially released in 2011 in the United States. In South Africa WEMA intends to make these traits readily available to smallscale farmers who normally cant afford to buy GM varieties through making “seed products available to African seed companies of all sizes, royalty free, so they can offer these hybrid seeds to smallholder farmers“.

However Angelika’s talk pointed to the fact that there has not been a lot of evidence to show that this innovation in genetic technology has managed to tackle the very complex issue of water stress in crops with Monsanto themselves stating that it can produce “moderate” yield improvements under “moderate drought conditions“. It is therefore not conclusive that it is able to perform well under drought conditions. As explained in a report by the Union of Concerned Scientists there are many complexities associated with drought such as that “droughts vary in their severity and their timing in relation to crop growth. Related factors such as soil quality affect the ability of crops to withstand drought”. This considered engineering traits suitable for drought a very complex process.

African Centre for Biosafety have warned that through WEMA making this drought resistant maize to small-scale farmers they may be undermining drought tolerance of farmer crops (developed over time and in situ) that are lost when farmers adopt new GM seed in the hope that it will be a silver bullet solution. It is important that in the face of technological solutions being put forward as the answers to such a complex problem that we don’t loose agricultural diversity that may hold the key to attaining resilience in a very uncertain climatic future.

 

GM in Spain (infographic)

Last week we collectively worked on creating an infographic that captured in a single image the main issues around GM Maize in Spain. Of course, as any infographic, it just highlights some of the relevant dimensions of the controversy of GM crops in Spain. But we think it can help to understand what is going on in the European country with higher number of cultivated area of GM crops. Actually, it is both a simplified, visual and updated version of what we tell in the section “Spain, a telltale case of the impossibility of coexistence” of our paper Just Existing is Resisting: The Everyday Struggle against the expansion of GM Crops in Spain.

It is also an infographic to be used in the interactive website we are preparing in which we are condensing much of the knowledge we have acquired through all these years of agri/cultures research.

Below you can see the result. Please, share it widely!

Bridging science and society with movie animations

One of the aims of The Agri/Cultures Project is to develop new ways to communicate scientific results and during the last 10 days I have been working with an artist to create a stop motion animation that narrates some insights from our latest paper (still to be published). This paper is focused on the everyday – mostly practical – forms of resistance to GM crops in contexts where there is unregulated coexistence, such as Spain.

As part of a social group whose job specifically aims at producing collective knowledge, scientists have a duty to share our research results and discussions with the rest of society, especially in the case of publicly funded science. But, unfortunately, very often scientific production remains trapped in a self-reproductive bubble primarily only accessible to a small elite.

In order to explore new ways to bridge the gaps between science and (the rest of) society and broaden the spectrum of audiences that might be interested in our research, we are producing a couple of short movies to help explain some aspects of our research. In fact, visualisation of concepts, experiences, practices, processes, and situations has been proven to be a great tool for enhancing learning processes generally and scientific knowledge specifically.

In our case, we thought that an animation could tell the story of the ordinary struggle of the actors within the non-GM agri-food systems to avoid GM contamination and fight the expansion of GMOs. We involved an artist in the process because artists are experts in the field of visual communication and can offer valuable resources to say things differently. Of course, a 3 minute video is not a 15 page text and there is certainly a notable degree of simplification required which represents a constant challenge in terms of balancing form and content. That is to say that watching our short movie will not be equal to reading the full paper. It is just a different format that helps us introduce some of the main ideas to different audiences (e.g people who normally would not spend their time reading scientific journals). As we will link the animation with the paper (which we hope to publish as open access), we expect it to be a double directional channel and a way to introduce non-scientists to scientific knowledge production.

Actually, although our short animation movie may not primarily be for scientists-as-audience, they might also find it interesting for other purposes. For instance, it can be an introductory tool to present the topic to students, journalists, NGOs, or even politicians and a way to create a context for generating fruitful discussions.

We’ll keep you updated about the forthcoming paper and about its short-animation movie release!
