Jason Glaser, CEO, La Isla Network outlines to Ian Welsh his work combating kidney disease in tropical sugar cane workers, and why famers providing water, rest and shade to workers in the field can mitigate serious health issues. Glaser explains how La Isla Network’s programme in Nicaragua is working to prove the effectiveness of rolling out water, rest and shade, and voices his frustrations with lack of progress while also highlighting some inspiring partnerships. They discuss the challenges around introducing more mechanisation in sugar cane supply chains – mitigating health risks while also developing other income sources for farm workers.
