Listen to the following transcript excerpt from an environmental science audio report:
«Welcome to *Horizontes Hídricos*. Today, we report from the high plateau of the Bolivian Andes, where indigenous Aymara pastoralists and hydrological researchers have united to revive degraded *bofedales*—high-altitude peatlands that act as natural sponges for the entire regional watershed. With tropical glaciers receding at unprecedented rates, downstream urban centers face severe seasonal water shortages. Rather than relying solely on costly concrete dams, this collaborative initiative restores ancient stone distribution channels while deploying solar-powered micro-sensors to track subsurface moisture levels in real time. Local herders manage grazing rotations to protect native cushion plants, while university hydrologists analyze telemetry data to optimize water retention across the basin. Early findings indicate that these revitalized wetlands have increased dry-season river discharge by twenty-five percent and stabilized soil carbon reservoirs. Organizers emphasize that the project's true strength lies in integrating ancestral territorial stewardship with modern ecological technology, offering a replicable, nature-based blueprint for climate resilience across the mountain regions of South America.»
Which of the following statements best identifies the main idea of this audio report?
- ASolar-powered micro-sensors have successfully verified a twenty-five percent rise in dry-season river discharge across the Bolivian Altiplano.
- Combining ancestral indigenous stewardship with modern hydrological technology creates an effective, nature-based solution for restoring wetlands and securing regional water supplies.Cevap
- CDownstream Andean municipalities must construct heavy concrete dams to replace rapidly diminishing high-altitude peatlands.
- DAymara herders are abandoning traditional pastoralism to focus entirely on operating university-led digital sensor networks.
