In Western São Paulo, excessive rainfall has begun to significantly impact the production of latex, posing challenges for local rubber tappers. During the harvest season, when producers typically gather latex in the early hours to avoid the day's heat, the rains have created logistical difficulties. One producer, Paulo Renato Cardoso from Indiana, São Paulo, anticipated to harvest around 30,000 kilograms of latex this year from nearly 10 hectares of land due to an increase in the number of mature trees and the natural advancement of the rubber cultivation which usually shows increased productivity by its fourth harvest.

Despite the positive outlook on production quantities, the unpredictability of rainfall has posed serious challenges in the collection process. When it rains shortly after the tapping process, the latex collected in storage cups is contaminated by rainwater, impacting its purity and quality. Often, producers find themselves unable to act promptly to coagulate the latex, resulting in significant losses. This interplay between weather conditions and agricultural productivity highlights the vulnerabilities faced by farmers in the region, driven by climate factors that they cannot control.

The ongoing challenges with latex production due to excessive rain may serve as a wake-up call for stakeholders in the rubber industry, prompting discussions around adapting farming practices or investing in technological advancements to mitigate the effects of weather disruptions. As the region moves forward in its harvest season, it remains critical to evaluate how climate variability can affect not only immediate productivity but also the long-term viability of latex production in Western São Paulo.
