Since China banned the import of plastic waste in 2018, plastic pollution has been having a growing impact on the people and ecosystems of Latin America. As the region imports an increasing amount of the world’s used and discarded plastic, new research shows that waste infrastructure in many countries is already buckling under the strain of dealing with domestic trash. As a result, much of the imported plastic is leaking out into the environment, with experts and the U.N. warning of major consequences for human health. A study published in April found that seven countries in the region — the Dominican Republic, Guatemala, Honduras, Mexico, Nicaragua, Panama, and Paraguay — have become plastic pollution hotspots, or PPHs, where high imports of low-quality plastics meet high rates of mismanaged waste. Global plastic waste generation reached 353 million metric tons in 2019 alone, of which 72% ended up being landfilled or dumped and just 9% was recycled, according to an OECD report. Much of the world’s plastic waste was previously destined for China, but in 2018 the country banned those imports. While Malaysia and Thailand took up much of the slack, Latin America also started importing more plastic waste, although the region has historically been an importer of difficult-to-recycle plastics. “Certain countries in Latin America have started importing more waste but they haven’t actually got the capacity to deal with [it],” Veronica Herrera, lead author of April study and an associate professor at the Luskin School of Public Affairs at the University…This article was originally published on Mongabay

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
