Ancient Maya knowledge helps Guatemalan farmers cut agrochemical use

9 June 2026 at 12:05
In the mountain villages of Guatemala’s Western Highlands, farmers are combining ancient Maya knowledge with modern sustainable farming techniques to protect their crops from pests and disease. Smallholders are creating homemade biopesticides using plants with strong smells and flavors to deter pests on their family plots. This is helping to cut back on the use of increasingly expensive agrochemicals, many of which have been labeled as dangerous to human health and linked to soil degradation. About 60 Guatemalan communities in the Western Highland departments of Sololá and Huehuetenango, as well as Chiquimula in the east, are working to revive these traditional techniques with support from the international development organization World Neighbors. Their focus is to restore and strengthen traditional knowledge, combining it with agroecological practices that help families produce surplus food they can sell to boost household incomes. “Traditional farming techniques are becoming popular because they are simple practices to apply, use local resources, and have proven to be effective,” Dayani Roche, a program associate at World Neighbors, told Mongabay via email. Rather than a single ancient recipe, farmers are using “a living combination of ancestral knowledge, local experimentation and more recent agroecological practices,” he said, which are “safer for families, soil, water and biodiversity than many chemical alternatives.” The Maya civilization, which once stretched across modern-day Central America, had a rich history of farming dating back to 2000 B.C.E. Its most celebrated agriculture system is the milpa, a form of intercropping that involves a mix of maize, beans and…This article was originally published on Mongabay

Tests suggest Russian satellites can jam GPS on a continental scale

8 June 2026 at 22:56

Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But uncertainty still hangs over whether such interference is intentional and if it could be more powerfully weaponized as GPS jamming with continental reach in the future.

The discovery came from an investigation detailed in a June 2 preprint paper by Todd Humphreys and his student Zach Clements at The University of Texas at Austin, along with Argyris Kriezis at Stanford University in California. By sifting through public data from ground-based stations with global navigation satellite system (GNSS) receivers, they identified a pattern of high-powered interference lasting less than 10 seconds each time but simultaneously detectable by ground stations across Europe from Norway to Spain to Poland, and even reaching as far west as Greenland and Canada.

By analyzing the ground station data from January 2019 to April 2026, the researchers found 75 days with at least one widespread GNSS interference event overlapping with the GPS L1 frequency band centered on 1575.42 megahertz. That represents the main band used for signal transmission by the US-made GPS satellite constellation and GNSS constellations from other countries.

In Peru and Brazil, extractivism threatens Indigenous people in isolation: Report

5 June 2026 at 22:58
Indigenous Peoples in Voluntary Isolation and Initial Contact (PIACI) in the Yavarí-Tapiche Territorial Corridor, one of the largest contiguous, intact forests in the Amazon and home to the world’s highest concentrations of PIACI, are under threat by extractive and large-scale industrial activities, which pose an existential threat to its inhabitants and the ecosystems they depend on. This is according to a new report co-authored by Earth Insight, the Regional Organization of Indigenous Peoples of the East (ORPIO), the Coordination of the Indigenous Organizations of the Brazilian Amazon (COIAB) and the Interethnic Association for the Development of the Peruvian Rainforest (AIDESEP). The report finds that oil and gas blocks overlap with 10% of the 16-million-hectare (39.5-million-acre) corridor, including almost 1.7 million hectares (4.2 million acres) of intact tropical moist forest, 907,000 hectares (2.2 million acres) of Key Biodiversity Areas and 713,000 hectares (1.8 million acres) of protected areas. “Pressure from hydrocarbons is increasing on the Peruvian side of the Yavarí Tapiche corridor,” Edith Espejo, senior program manager at Earth Insight and author of the report, told Mongabay over WhatsApp messages. “Our report serves as a warning for the irreversible harm that could take place if these oil blocks move into this corridor. Mining concessions within and on the peripheries of the corridor also pose a threat of encroachment and contamination of waterways.” A critical corridor for ecosystems and Indigenous communities The Yavarí-Tapiche Corridor covers Brazil’s western border states of Amazonas and Acre and Peru’s Loreto and Ucayali departments in the Amazon…This article was originally published on Mongabay
