Mitigating change in climate relations: breeders and modelers of Africa unite for climate-smart crops

From 6 to 8 December, CCAFS theme 1 organized a workshop staged on the Addis Ababa campus of the International Livestock Research Institute (ILRI). The workshop titled ‘Developing climate-smart crops for 2030 world’ involved over 40 participants from 16 countries, broadly divided along either side of the breeding / modeling continuum.

At the onset of the workshop, that continuum looked more like a chasm.  Modelers and breeders have long been operating indifferently to one another. But climate variations are perhaps urging a change in perspectives and relations with one another. Breeders seem to have dismissed models – whether for climate-change or other issues – for their breeding work with respect to their absence of context and attention for the reality of breeding crops. In turn, modelers have found it difficult to get breeding strategies to consider the pertinence of their own models, to look outside the breeding box. The only cases known of interactions between the two communities around climate change seem to have focused on the symptoms (e.g. dealing with drought) rather than a strategy to mitigate climate change and develop climate-smart crops.

The 2030 climate-smart crops workshop was a first attempt in the CCAFS programme to try and collectively develop a broader picture of the challenges of breeding in an increasingly climate-uncertain future by bringing together members from these two communities from East and West Africa. During three days collective discussions identified the broad challenges of a 2030 world for breeding strategies, the regional issues that affect breeding and ultimately the specific challenges for each of the four key crops in consideration in the CCAFS programme: Bananas, beans, rice and sorghum.

It seems obvious that crop breeders have to be involved in developing climate-smart crop strategies. Indeed, only breeders really understand the long term process of breeding (over ten years for bananas and generally rather long periods for better quality crops). Modelers may come up with valid conceptual frameworks but implementation rests with breeders. However, the imminence of novel climates and the increasing recognition of the complexity surrounding climate change calls for a different approach to ‘breeding business as usual’.

Breeding can no longer be restricted to one location. Multiple locations allow a better understanding of the climate variations affecting their crops, their livelihood and beyond. Breeding also needs to consider various other aspects: the (changing) needs and demands of the population in the target environment, the crop quality and its constraints, the likelihood of various climate scenarios that might affect breeding, the importance of developing drought tolerant crops etc.

Why did this not happen before? Breeders are sometimes isolated, as illustrated by the chasm mentioned above; also among breeders there seems to be little interaction and limited options for training. Yet, the workshop participants highlighted a variety of options to work together for climate-smart crops – one that relies on more cooperation with modelers and other actors. How can that cooperation take shape?

Ways forward for climate-smart breeding strategies?

More interaction is required at all levels: among breeders, with modelers, but also with a wider variety of specialists that all have a role to play in developing robust breeding strategies: farmers, climatologists, traders, consumers, nutritionists, pathologists, entomologists, agronomists, physiologists, soil scientists etc.

This interaction can take various shapes:

  • Interaction via information-sharing platforms or workshops like this one;
  • Developing incentives for breeders to consider modeling inputs;
  • Additional funding to develop smarter breeding programmes;
  • Involving breeders in the development of new agro-climatic analysis and modeling tools;
  • Crucially, breeders should be included from the start of any modeling initiative that concerns them, as was repeatedly pleaded throughout the workshop.

These solutions came up as only one set of answers (among others) within each crop group. The workshop brought breeders and modelers together in those crop groups and each of them managed to develop: a vision for how their crop should evolve by 2030, an idea about the approach they would follow to achieve that vision, a list of constraints they might encounter and crucially a typology of traits and target environments they should focus on (all presentations are available on the CCAFS slideshare).

Beyond solutions, the workshop also helped forge new alliances. One of the most promising is between CCAFS and The West African Centre for Crop Improvement (WACCI).

One workshop is a modest step forward and the lasting of this initiative will be put to test in the absence of concrete joint activities, yet the climate is definitely warming up in the relations between African breeders and modelers and for once that can only be positive news.

One response to Tortillas on the Roaster: new study to support maize/bean farmers in Central America to adapt to climate change

  • Natalie says:

    The rich, industrial countries like the US and China remain highest emitters of CO2, yet countries like Guatemala will be the ones immediately effected by the costs of climate change. It is sad to see that mistakes of wealthy nations ruining the two food staples in South America. In the US, agriculture can be altered with money to invest in other crops, whereas many people in poorer countries do not have this option. Ultimately, the countries emitting most greenhouse gases will not be the ones immediately affected. The US has seen worsening tropical storms, however our as many as one million corn and bean farmers. If two main dietary staples are affected, the small farmers may not be able to bounce back from these changes like big agriculture is in the US. The US would respond to changing rainfall patterns with increased irrigation to no end, which is not an option for all countries.

    The only solution for problems like those mentioned in South America would be a worldwide climate plan. Although these efforts have been underway for years, nothing substantial has occurred. Sadly, it seems unlikely that any real changes will come about without a large event that will change the minds of the rich countries in power.
