How Behavioral Science Solved Chicago's Plastic Bag Problem

Portugal has gone perhaps the farthest in decriminalizing drug use. It hasn't stopped drug usage, but it has reduced deaths, the spread of H.I.V., drug crime, and imprisonment.

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

In efforts to diminish violent crime, police agencies are revisiting a model law enforcement strategy of the 1970s, "community policing," as an alternative to the more recent "broken windows" style of the late nineties. Research substantiates its effectiveness, too, in building citizens' trust of law enforcement, helping a community's ability to solve its own problems, and, in turn, decreasing crime rates. Despite redefined priorities in the wake of 9/11 and post-recession budget cuts, community policing is again on the rise and bringing positive results, too.

Plastic is a leading cause of much of the world's pollution problem. But thanks to a discovery in a Japanese recycling center, scientists believe they may have identified a substance that can drastically reduce the amount.

In 2017, New Jersey eliminated the cash bail system – meaning that potential offenders awaiting court could not be held in jail for money. Instead, judges use an algorithm that considers the individual’s criminal history, flight risk, and threat level to the community. As New York considers doing the same, it looks the impact it has made in New Jersey.

At one Boston public school, teachers are updating curricula to provide students with history lessons that contextualize current national debates about immigration policy.

A pilot project in several American cities has provided a large amount of data on how residents use streets where vehicular traffic is restricted. The initiative tested out ways to calm traffic, provide space for families to convene and exercise, and provide safer bike lanes. A transportation analysis firm was able to provide detailed analysis for how each city responded to the changes, opening up ways for governments to "implement the best project for that specific need and measure against those goals."

Research shows that city council meetings are dominated by older, male and longtime residents. One Mayor is trying to change that. Under the leadership of mayor of Svante Myrick, in Ithaca New York, the city council began to offer childcare during city council meetings. “We don’t think anyone else has done it.’ People are using it, and some are even hailing it for it’s inclusionary nature. “Now we’re starting to see new people at meetings. People are using the childcare service.”

A grassroots campaign ended gerrymandering in Michigan by passing an initiative requiring districts be drawn by citizen-commissions rather than politicians. The all-volunteer campaign went door-to-door collecting enough signatures to get the initiative on the ballot and used creative voter-engagement techniques to sustain the support. Once the ballot initiative passed, 9,300 people applied for the first commission. A third-party firm ultimately selected four Democrats, four Republicans, and five non-partisan people as commissioners, who worked together very well to redraw districts.

Securecycle is a nonprofit working to reduce the number of young students not attending school in Ogun State, Nigeria. The organization collects old jeans to turn into bags and finds students who are, or will likely, drop out of school to teach them bag production and give them a scholarship to finish primary school.
