Desalination, water, and war Attacks on civilian systems, including water systems, must be condemned and punished under the laws of war.

My new opinion piece on the recently reported attacks on desalination plants in the Middle East.

Spatially explicit global assessment of cropland greenhouse gas emissions circa 2020 - Nature Climate Change Emissions from croplands are an important source of GHG emissions that can be shaped by management. This study presents maps of emissions globally for different crops, showing that drained peatlands, ...

Very proud that Project Drawdown scientists contributed to this effort to map greenhouse gas emissions from agriculture.

Important work! This helps us highlight where the biggest problems are, and where we need to focus our solutions work.

Global spatially explicit crop water consumption shows an overall increase of 9% for 46 agricultural crops from 2010 to 2020 - Nature Food Using the most recent Spatial Production Allocation Model 2020 crop data, agricultural green and blue water consumption is estimated. Water use increased by up to four-fifths for major crops in the past two decades.

This data platform charts the health of nearly every freshwater body on Earth. Here’s what it reveals The Freshwater Ecosystems Explorer offers what experts call an unprecedented look at the world’s lakes, rivers and wetlands, which are increasingly under pressure from things like climate change.

🌍@unep.org’s Freshwater Ecosystems Explorer reveals pollution, shrinking lakes, & climate impacts on rivers worldwide. But recovery is possible—some water bodies are bouncing back! 🧪

Environmental exposure levels of antibiotics in global rivers. Total risk quotient is calculated as the sum of individual risk quotients of all 40 antibiotics in the global river system under low-flow conditions.

As consumption of antibiotics has risen around the world, so has antibiotic pollution of rivers. A model identifies the rivers most likely affected and the drugs most likely to be found in the water. In PNAS Nexus: academic.oup.com/pnasnexus/ar...
