One-third of all food produced globally by weight is lost or wasted between farm and fork — that’s more than 1 billion tonnes. Converted into calories, this equates to 24% of the world’s food supply going uneaten. At the same time, 1 in 10 people globally remain malnourished.This scale of food loss and waste harms not only human health and nutrition but also economies and the environment. Wasted food takes a major financial toll, costing the global economy more than $1 trillion every year. It also fuels climate change, accounting for approximately 8%-10% of global greenhouse gas emissions.

Since the Industrial Revolution, humans have emitted more than 2,000 gigatons of carbon dioxide into the atmosphere. (A gigaton is one billion metric tons.)
This concentration of CO2 and other greenhouse gases in the air causes the climate change impacts we’re experiencing today, from forest fires to stifling heat waves and damaging sea level rise — and the global community is still emitting more each year. Unless we make serious changes, climate impacts will only continue to intensify.

News coverage of the Amazon rainforest in the past few years has been grim. Deforestation rates in the Brazilian Amazon increased 15% during 2021, with 9,770 square kilometers of native vegetation lost, an area the size of Puerto Rico. If deforestation continues, a tipping point may be reached, where the Amazon rainforest becomes a net emitter of carbon rather than a carbon sink. Aside from fueling climate change, deforestation poses risks to biodiversity: the Amazon is home to one out of every 10 species known to science. The problem is that the current regional economic model in the Amazon is highly dependent on resource extraction and exploitation, pushing the rainforest closer to its tipping point. Changes in land use account for almost half of Brazil’s greenhouse gas (GHG) emissions, and of those emissions, approximately 80% are linked to deforestation in the Amazon. It’s clear that heavily forested nations like Brazil need a new economic model — one fit for a low-carbon, sustainable and prosperous future. Enter the “bioeconomy.”

A New Yorker may not think about the forested Catskills Mountain Range upstate as she pours a glass of water. Londoners probably don’t consider the Amazon rainforest as they watch the rain falling on city parks. And folks in Addis Ababa are probably not thinking about the Congo Basin as they eat injera, an Ethiopian staple made from the grain teff. And yet, forests near and far affect these urbanites’ daily lives far more than most people realize.

Back in the 1990s, researchers undertook the Human Genome Project, a 13-year journey designed to enable a new era of innovation in medicine. By assembling and sharing vast amounts of data to uncover the secrets behind the genetic determinants of disease, this project transformed the medical industry and led to innumerable breakthroughs. Now, researchers are extending that model of innovation to battery science with an eye on impact at a global scale.

We know that deforestation is an ongoing, devastating problem — satellite data has been tracking it closely for years. But another question has remained more elusive: How much new forest is growing? Thanks to new data from researchers at the University of Maryland and WRI, we now have an answer: Tree cover — lots of it —is cropping up all over the globe. All told, 130.9 million hectares of land gained tree cover globally between 2000 and 2020, according to the study. Put together, that’s an area larger than Peru.

When most people think of coastal ecosystems, they think of mighty mangrove forests and colorful coral reefs. But these ecosystems are only the tip of the iceberg — there’s more beneath the surface, specifically seagrass. Seagrasses provide humans with countless goods and services — everything from food security to shoreline protection to clean water. They are found in almost every sea around the world, with more than 1 billion people living within 100 kilometers of seagrass meadows. Yet most people are unfamiliar with the many benefits these plants provide to humans and animals alike. Here, we answer key questions about seagrasses: What are they, where are they and why are they important? Let’s dive in.

While efforts to reduce GHG emissions should always take priority, meeting climate goals will also require carbon dioxide removal (CDR) — systems that remove carbon directly from the air — likely at the billion-tonne scale by mid-century. Carbon removal is needed not only to balance out residual emissions that cannot be or are not eliminated by 2050, but also to reduce the high concentration of carbon dioxide in the air, which is triggering increasingly devastating climate change impacts.
