Brilliant ideas don’t always pan out. In the realm of humanitarian development, innovations that fall flat affect more than just investors’ bank accounts.

That's why a small team at an Oregon university has set out to become the testing ground for the world's possibly brilliant humanitarian inventions. This post is the first of a Global Envision series on how they're doing it.

While promising products like self-adjusting eyeglasses or low-fuel stoves generally undergo some sort of lab testing prior to introduction, they often perform differently than expected once they’ve reached their destination due to environmental or cultural differences. Rather than waiting to see results after the fact, Portland State University is working on a grand plan to evaluate magic bullets like these before they hit the developing world.

It's a mission that straddles two separately funded PSU programs. The internationally focused Sustainable Water, Energy, and Environmental Technologies Lab shares a roof with the domestically focused Green Building Research Lab. The latter is stocked with equipment that, as PSU architecture professor Sergio Palleroni put it, "can create any environment on earth, any weather condition." PSU researchers can use the equipment to closely mimic the environmental conditions of the destination country and closely measure products’ performance in all sorts of climatic conditions.

The SWEET lab, meanwhile, focuses specifically on putting low-cost sustainability products through a battery of tests.

"We want to become the Consumer Reports for the developing world," said Palleroni, standing in a lab room devoted to the subject. That means not only ensuring that products function as they should, but also measuring how well they function — and how similar products stack up against one another. Two small, low-fuel, low-emission stoves burned side-by-side when we visited, various sensors measuring their ouput and rate of fuel consumption.

In forthcoming posts in this series, we’ll be exploring a few of the PSU labs’ projects. Stay tuned.

Rwanda, 1994: Hundreds of thousands of people, mostly members of the Tutsi minority, are slaughtered by their ethnic Hutu neighbors in one of the worst genocides of the 20th century.

Today, the words "Hutu" and "Tutsi," once ripe with divisiveness and hatred, are no longer spoken on the streets of Rwanda. Reconciliation efforts have led perpetrators and survivors to work together to rebuild their common livelihoods.

Photographer Adam Bacher is documenting the efforts of this New Rwanda, giving readers of his blog a reason to be hopeful about the country's future. He provides a sweeping visual tour of reconciliation efforts, from a progressive rehabilitation center for former child soldiers, to a community-service program for former prisoners who rebuild the homes of survivors. He also documents programs meant to empower victims and rebuild the Rwandan economy. He visits a community-driven hospital construction project for infectious disease patients, and follows a non-profit that teaches vocational micro-business skills to children orphaned by the genocide.

The inspiration behind Bacher's work lies in the resilience of the Rwandan people:

Today Rwanda is an example of peace. The people have chosen not to allow themselves to become captive to decades of retributional killings. Distinctions between ethnic groups, political extremism, wide spread corruption, media manipulation, and other factors that led to the genocide have all but disappeared. Rwandans are working hard to reconcile their differences, and grow themselves out of poverty - toward peace and prosperity. They are an example to the world of what is possible.

In the future, farms will line the cities' skylines. Photo: Editrix, Curbed SF (flickr)

In the future, farming on expansive tracts of rural land will give way to 30-story-high self-sustained, temperature-controlled, organic farms that are only a city block away.

You might be thinking that this is a far-fetched idea from some science-fiction novel, but in fact it’s the very real brainchild of Professor Dickson Despommier from Columbia University. Along with some of his graduate students, Despommier came up with this idea for “vertical farms" in 1999.

Despommier believes that he has devised the perfect solution to the growing food, water and energy crisis: bringing farms to where a majority of the population lives — cities. Building farms vertically will save land and increase the world’s agricultural output.

Despommier envisions vertical farms as multi-leveled greenhouses that are built to skyscraper proportions. His website is full of charts and graphics and presentations — many produced by his graduate students — that presumably show how vertical farms will be able to produce food not typically found in greenhouses, like corn, wheat and even rice. The entire community will be engaged in the project, with a farmer’s market in the building and possibly even a restaurant.

This new type of farming has numerous advantages over more conventional methods. The most obvious advantage is that vertical farms will have year-round production with no worry of weather-related crop failure. They are also more environmentally friendly because there will be no plows, tractors, or shipping necessary. Furthermore, Despommier designed these farms to use alternative energy as their main source of power.

The project is still very much in its developmental stage, but the most up-to-date plans and designs are available on the project’s website.

Planners in cities like New York and Portland see great potential behind the idea and have already started developing vertical farm proposals. Having skyscraper farms in our cities might not be too far away after all.

A bike can change a life.

The benefits of a bike can range from awakening your inner child to being an eco-friendly commuter. In a developing country, however, the simple bike becomes a locally sustainable method of alleviating poverty and building healthy communities.

The bicycle means greater access to educational and economic opportunities. (Cool fact: A bike can go three or four times faster than the pedestrian and uses five times less energy.) But in communities where people make only a few hundred dollars a year, a bicycle that costs an average of $100 is financially out of reach.

To help bridge the gap, various organizations have sprung up as bicycle distributors for developing communities mostly in Africa.

World Bicycle Relief, an organization fighting the HIV/AIDS crisis in Zambia, describes the power of bicycles in its mission statement:

Simple, sustainable transportation is an essential element in disaster assistance and poverty relief. Bicycles fulfill basic needs by providing access to healthcare, education and economic development. Bicycles empower individuals, their families, and their communities. Our mission is to provide access to independence and livelihood through The Power of Bicycles.

Organizations like this depend on donated bikes, which they then ship to community-based organizations that employ and train locals as bike mechanics. In Namibia, the Bicycling Empowerment Network has bicycle workshops (called Bicycle Empowerment Centres) stocked with tools and bicycle parts that act as the hub for bike distribution and repairs.

Even grassroots groups in the U.S. have joined the cause. Bikes to Rwanda, a project supported by Stumptown Coffee in Portland, Ore., ships cargo bicycles to farmers in a Rwandan coffee cooperative.

With today’s gas prices, cycling is a more attractive alternative for residents of places from Amsterdam to Zambia. But bikes aren't limited to transport anymore. They can be modified to sharpen knives, double as an ambulance, and even filter and store water — all innovative adaptations geared towards positive social change.

Ciclovía Documentary shot by Streetfilms

Bogotá, Colombia is holding a 70-mile long block party. And everyone’s invited.

Ciclovía — "bike path" in Spanish — is an event that closes down major roads for pedestrian use every Sunday and holiday from 7 a.m. to 2 p.m. Created in 1976, it rapidly grew from eight miles and 140,000 bicyclists to 70 miles and an average of 1.5 million weekly riders. Ciclovía is championed as a community building event that attracts people from all backgrounds for a day of biking, walking, skating and dancing in the streets.

In the above video, Bogota’s former park commissioner Guillermo (Gil) Penalosa discusses Ciclovía’s main appeal: social integration.

You will see people in $5,000 bikes and others in $50 bikes, and all having the same fun! Rich and poor, young and old, men and woman, tall or short... ALL!

Cited for “endless benefits” such as the improvement of personal and public health, Ciclovía has inspired other cities to develop similar programs, including Guadalajara, Mexico; Quito, Ecuador; Santiago, Chile; and Paris, where an expressway along the Seine is transformed into a pedestrian refuge one month out of the summer.

Cities in the U.S. are also developing similar programs, starting with El Paso, Texas. This Sunday Portland, Ore., is clearing 6 miles of roadway for six hours in its inaugural "Sunday Parkways." New York Mayor Michael Bloomberg announced his city's plans for Ciclovía-like event this August that would stretch from 72nd to the Brooklyn Bridge along Park Avenue.

Events such as Ciclovía are not only free, but they also bring all sorts of people together to get healthy and build a happy community. It seems like a no-brainer that every city should have a Ciclovía!
