A matter of trust

Health researchers and workers use their training and the treatments available to them to prevent and treat illness. But they cannot bring their expertise to bear if they do not have the trust of the people that they are trying to treat.

This August, in the Democratic Republic of the Congo, communities in the midst of an Ebola outbreak continued traditional rural burial practices that include touching bodies, despite health workers’ advice on sanitary burials. Residents in the village of Manbangu burnt down a health centre and injured an Ebola health-care worker after one resident died of Ebola. Sometimes fear and misinformation drive even more violent behaviour: in a 2014 outbreak of the disease in Guinea, residents of the village of Womey killed a group of eight visiting health workers, journalists and government officials.

Squeezing water from a drying Himalayan desert

When water does come to the former Kingdom of Lo, in the rain shadow of the Himalaya, it is often sudden and violent. A storm may boil over a mountain ridge, a glacial dam may collapse, or meltwater may surge through a gorge. But slower, less-visible changes are forcing the region’s farmers and herders to reconsider their relationship with water and each other.

The next step on the energy ladder

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.

Al rescate del chile más emblemático de México

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
