Dear colleagues,
Today’s statement by Ahmadou Aly Mbaye (University Cheikh Anta Diop, Senegal) focuses on the case study of climate change, population dynamics and food security in the Sahel
Regardless of climate change, the Sahel has long been hit by chronic poverty, high population growth and conflict which are major drivers of food insecurity in the region. Since natural resources are the main source of livelihoods, the Sahel is particularly vulnerable to climate change. Climate change can exacerbate the already existing food insecurity issues by disrupting agricultural production and food price.
In his statement, Aly has highlighted the key areas where climate change impact on food security is evident. First, salt-water intrusion, increased salinity levels in agricultural land and increasing flood hazards due to sea level rise in the coastal areas can threathen food security. Second, climate change has contributed to the reduction in arable land due to reduced humidity and increased aridity. Third, production of staple crops is subject to high volatility due to climate change and other factors. Fourth, changing weather patterns can affect crop yields which in turn contribute to rising food price. Fifth, there is some evidence showing that food price is positively correlated with conflict events. Climate change thus may contribute to increasing conflict through influencing food price.
Aly concludes by pointing out about high population growth in the region, especially in the urban and coastal areas which put an extra pressure on food security. Poor governance also impedes the capacity to adapt to climate change.
Please join us on the discussions about the Sahel case study or other regions and context which are facing multiple drivers of food insecurity. The COVID-19 pandemic has also exacerbated the already existing challenges in such region.
Which area of interventions is urgently needed is also worth thinking about.

This echoes a PERN seminar we had in 2007 on similar issues.
Here is a presentation I did –
‘Comments on P-D-E, livelihoods, and agrarian change in the Sahel’ Panel contribution to the Population-Environment Research Network Cyberseminar on Population-Development-Environment Linkages in the Sudano-Sahelian Zone of West Africa (September 2007) Simon Batterbury
https://www.populationenvironmentresearch.org/pern_files/papers/Batterbury_SahelCyberseminar.pdf
I think the key points [listed as research questions at the end] are that back then at least, migration and urbanisation were already becoming the prevalent adaptive responses to drought, land pressures, and food shortage. Regional-level investigations tend to miss the nuances of local adaptive strategies, conflicts, and so-on which are too readily blamed on population increase or region-wide climatic change. I missed the prevalence of land grabbing, now much worse, and violent movements were not so prevalent.
One question was “- If agriculture suffers in many parts of the Sahel over the next 50 years, does this really _matter_ given the stronger monetization and stronger international linkages and to neighbouring regions and beyond? If it does not really matter, will we be following the views of the agrarian political economists, rather than the P-D-E experts, and seeing an increasingly ‘globalised’ Sahel producing less of its own food and importing more? (Toulmin and Guèye 2005)” Demographic variables mean far less if Sahelian localities have ‘globalised’ through successful [and unsuccessful or temporary] migration and remittances, and if lack of access to productive land is determined by large and corrupt land grabbing.

Thanks Simon for sharing your paper back in 2007. It is indeed important for us to revisit the same case study used back in 2007.
I’m not an expert of the Sahel region myself, but I think it’s highly relevant to revisit your remark on whether the Sahel would import more food and produce less on its own. If this is currently the case, the climate impact on food security can be indirectly through food supply chain and food price.
Tomorrow’s statement on technological solutions to food security challenges is relevant to the Sahel case as well.
Best wishes,
Raya
