CottonConnect and Assimila address health issues caused by climate change

CottonConnect and Assimila, supported by the European Space Agency’s EO Science for Society Programme, have set up Combat Against Climate Change on Cotton Communities, known as C5, a feasibility study exploring how climate advice could help farmer decision-making at key stages in the cotton production cycle.

C5 is designed to help farmers mitigate threats to their health, in addition to their crops, and is the first system of its kind to focus on the lived experience of cotton farmers and pickers.

The feasibility study investigates how linking Earth observation and climate analysis can help farmers to plan for extreme climate change that may affect their ability to farm. It comprises two main elements, a health ‘stress’ index to identify where health risks (such as heat stroke and exhaustion) are increasing, in order to plan and manage farming activities, and an alert system providing extreme weather warnings, alerts and actionable information at key milestones during the cotton calendar.

The true colour Sentinel-2 images use bands which roughly correspond to red, green, and blue on the colour spectrum, and the result looks like the world as humans see it.

Limit worker exposure to harmful heat

C5 information will be disseminated to farmers through text messages, radio broadcasts and outreach groups and aims to limit worker exposure to harmful heat, avoid major risks such as flooding, and improve related activities such as crop production and livestock rearing that are also threatened by climate change.

Assimila will provide Earth observation and climate data analysis and CottonConnect has connections to cotton farmer communities and facilitates data collection. The C5 prototype is being developed for users in Bangladesh with a view to rollout to other major cotton producing nations.

Impacts of climate change

CottonConnect CEO Alison Ward said, “We know that smallholder farmers are already facing the impacts of climate change. This significant partnership supported by the European Space Agency, brings Assimila’s expertise in Earth observation, modelling and computing together with CottonConnect’s experience of working with rural communities, to address climate-related changes that we see all too often among our farmers. We’re optimistic that access to improved forecasting tools will help them develop more sustainable cultivation practices by helping them understand, monitor and even predict the environment in which they are farming.”

Assimila director Andy Shaw said, “C5 will support cotton farmers adapt to changing climate factors by providing state-of the-art, up-to-date information focused on issues affecting the health of cotton growers. Exploiting advances in Earth observation and climate data science, C5 will generate a range of hazard indices and alerting services to inform support mechanisms for farmers and workers.”
