These storms can flatten entire banana plantations, devastate cocoa and coffee farms, and flood rice preddies, leading to long-term production losses. For example, Hurricane Maria in 2017 destrucyed up to 80% of Puerto Rico coffee crop.

Even in temperate regions, seare thunderstorms wigh hail can strip leaves, breaks stems, and bruise fructs, resulting in total crop loss. The U.S. Greet Plains experimentares hundreds of hailstorms annually, with insured losses freepently exceeding $1 billion. These damages nott only reduce excitate excitate eields but also presume costs for replanting and pess control.

These practices improwize soil health, increage water retention, and support biodiversity, making farming systems better able to with stand climate shocks.

For example, examinating trees into croplands provides shade that reduces heat stres on crops and livestock, prevents soil erosion, and generates additional income frem fenets or timber. Cover crops protect soil from erosion, fix nitrogen, andd supress weeds, reducing the need for synthetic inputs.
