Sandwip Island in southern Bangladesh almost has it all. It sits in the estuary of the Meghna River, which washes the island with rich, fertile silt, while plentiful sunlight helps coconuts, mangoes and pineapples to grow. It was once home to pirates but now thrives on honest trade. The main downside is that none of the 350,000 people living on the island have a connection to the national grid.
For years, only the wealthier Sandwip residents could generate electricity, by buying small diesel generators. About a decade ago, Bangladesh began promoting solar home systems (SHSs): small, stand-alone, rooftop photovoltaic devices that can reach poorer households. But power generation on an individual scale has drawbacks. There is a limited supply of subsidized diesel, so generators cannot be on all day, and they are noisy, polluting and have high maintenance costs owing to the low-quality fuel that is often used. And a typical SHS provides a maximum output of just 500 watts — enough for a few light bulbs and a mobile-phone charger, but too little for a hand blender or water pump.
To thrive, small enterprises need dependable electricity around the clock. So in the absence of the national grid, Sandwip went for the next best thing: a hybrid solar–diesel minigrid.

One fresh, sunny morning this spring, a dozen ex-convicts gathered around a table in a back room down a quiet side street of London. Considering the company, the scene was sedate. Someone with a manslaughter conviction stubbed out a cigarette. Onetime drug dealers snacked on croissants. A man with tattoos covering his substantial forearms shuffled reading material on a table. Someone who once served a prison sentence for embezzlement put a kettle on and offered the others tea.
No police officer would worry about this crowd: It was an academic congregation of so-called convict criminologists.
Over the past few decades, some ex-convicts have turned to academia, aiming to put their experience “inside” to good use. They use their knowledge of the criminal justice system to select research questions and design studies. They use their history to gain prisoners’ trust. And they work to counteract what they see as a strong bias in academic criminology toward the perspectives of authorities in the criminal justice system.

Una plaga de mosca blanca cayó hace dos décadas en los campos de chilhuacle amarillo, rojo y púrpura de la familia Martínez. El chilhuacle es el chile estrella en varias versiones del plato insignia de Oaxaca –el mole, claro–, y por mucho tiempo los cocineros habían estado pagando altos precios por las notas ahumadas y cítricas de este chile. Pero su costo estaba a punto de subir todavía más. Continue reading Al rescate del chile más emblemático de México
A plague of whiteflies descended on the Martínez family’s fields of yellow, red, and deep purple chilhuacle in southern Mexico two decades ago. Chilhuacle is the star chilli in several versions of Oaxaca’s signature dish – mole – and cooks had long paid a premium for the chilli’s unique smoke and citrus flavours. But its cost was about to climb higher.
