Cropland can easily be found time and again at the heart of the key concerns on the environment beat, whether climate, water, chemicals or, of course, land. The latest Reporter’s Toolbox shares a high-quality, mappable database that can serve up stories on more than 100 categories of crops, with numbers drawn from satellite imagery. Plus, a pro tip on using the data smartly.

An important federal database that tracks Arctic ice and snowmelt — which help address concerns like sea level rise and fresh water resources — is facing funding cuts and reductions in services. The latest Reporter’s Toolbox looks at the kind of high-quality information the National Snow and Ice Data Center can provide environmental reporters, including for local stories. That is, while it lasts.

Many local government decisions come down to a key factor: walkability. And that’s not just a question of transportation infrastructure. As the latest Reporter’s Toolbox notes, walkability is also an environmental consideration. To turn that simple truth into stories about the built environment, here’s a high-quality, mappable walkability index. How to use the database smartly, plus questions to ask that will get your reporting started.

Public databases — a boon to good environmental reporting — have long been a priority for the U.S. Environmental Protection Agency, as evidenced in its just-published “open data plan.” But as an analysis in the latest Reporter’s Toolbox notes, that pioneering approach may succumb to Trump 2.0 policies. What’s at stake and what’s already being lost.

For environmental journalists looking for data riches to help tell their stories — whether about urban heat islands, sea-surface temperatures or air pollution — NASA has the satellites whose sensors capture insights galore. The latest Reporter’s Toolbox offers an introduction to the U.S. space agency’s incredibly extensive data portal, and how to get started amid the wealth of information (caveat: before it’s gone).

Lead-contaminated drinking water has long been a widespread worry, but one big challenge has been locating the many lead service lines around the United States. The latest Reporter’s Toolbox points you to a mappable database to help address that problem, with current, detailed data filtered through the U.S. Environmental Protection Agency. Learn more about this resource and how to best use it.

Streamflow data gathered by thousands of U.S. Geological Survey gauges helps track the country’s floods and droughts. But it may be lost if the Trump administration follows up on a decision not to renew leases of USGS water science centers that read the gauges and disseminate the measurements. Reporter’s Toolbox on the value of this database and the risk of its loss.

Environmental journalists need environmental data, even as it’s being stripped from government sites by the Trump administration. That’s where a band of programmers organized into the Public Environmental Data Partners comes in. The latest Toolbox reports it’s rescuing wiped data and making it accessible to reporters. Learn who’s behind the project and get an overview of some of the datasets being restored.

Even as U.S. government agencies rush to wipe climate change information (or even the mention of the word climate) from their websites, others are racing to reconstruct lost data elsewhere. Case in point is a rescued database on climate risks preserved by The Guardian. The latest Reporter’s Toolbox has more on the preserved database and how best to use it.

With many states dominated by a few powerful industries — whether oil, mining or agriculture — the influence of campaign dollars can have an outsize effect on legislation, even to the point of corruption, notes the latest Reporter’s Toolbox. So while the U.S. Congress may be languishing, environmental journalists can dig up stories on lobbying at the state level using a powerful data source.
