Brief:

RSA in partnership with Google Deepmind: Apply AI

How might we empower communities to use AI to tackle the local challenges of climate change?

the issue
 

40% of Earths land is used for agriculture. Agriculture has an extreme
reliance on chemical fertiliser (NPK). This is due to inaccurate knowledge (with farmers provided laboratory soil test one per field and does not provide in time data), and apply the fertiliser with extremely heavy machinery.

the solution
 

An AI soil sensor and app that promotes regenerative agriculture and accurate fertilisation to diminish farmers’ contribution to climate change while fostering community-led mitigation of climate challenges.

Inbuilt fertiliser
 

The soil sensor has an inbuilt fertiliser. The fertiliser utilises AI and Chempeg technology which collects NPK data and sprays fertiliser in 10 meter radius based of the data and soils needs. This innovation aims ensures accuracy, and reduces extreme costs and environmental damages of traditional application.

fertiliser costs rise by 200% annually, terra hex offers smart savings for farmers.

hex app
 

The Hex app provides the data collected by the soil sensor providing accurate and in time data. The app provides unbiased and reliable information for farmers to increase their knowledge and adapt their agricultural practices.

hex community
 

Addressing farmers limited time and establish community participation in mitigating climate change, the Hex app, provides an area for farmers to share ideas and be provided awareness of financial support through providing location specific grants and incentives through discounts and benefits for performing regenerative agriculture.

environmental impact
 

Terra Hex supports regenerative agriculture by helping farmers reduce over-fertilisation, mitigating their contribution to climate change while improving soil health. This enhances soil resilience to climate threats like flooding, boosts biodiversity, and ensures long-term agricultural sustainability. Ultimately, Terra Hex provides valuable information to support future generations and the longevity of agriculture.
