S1 E12: Shelter: Building Better Cities

Shelter: Building Better Cities

Half the world's population live in cities, and by 2050 the figure will increase to two-thirds, or about 6 billion people. The environmental impact is already extensive. As the global population expands, so too do pollution and pressure on resources.

"earthrise" travels to Colombia and Singapore to meet some of the people who are finding ways to meet growing demand while also making our cities more sustainable. Juliana Schatz heads to Bogota to see how Conceptos Plasticos builds homes out of discarded waste. Russell Beard travels there to meet some of the entrepreneurs who are helping the island city-state of Singapore earn its green title.

Upcoming Airdates

Rewilding Patagonia

Three-quarters of all land on Earth is now significantly affected by human activity and the few remaining pockets of wilderness are themselves at risk of becoming ecological deserts. Agriculture, industry, urbanization, climate change — all these are decimating ecosystems and destroying biodiversity. Some 60 percent of the world's animals have been wiped out since the 1970s.

Food for Thought

A look at the state of global food security amid rising concerns about the world population and climate change.

In New Haven, Connecticut, a community of scientists, fishermen and foodies are redefining their relationship with the sea using 3D ocean farming. In Africa, farmer-managed natural regeneration is restoring farmland to improve food security. In Holland, scientists are racing to future proof our planet against our love of meat.

Feeding The Billions

With global demand for food set to increase by nearly 70% by 2050, sustainable food production is one of the biggest challenges for the future. The food industry is one of the most ecologically damaging industries and we will need to completely rethink its approach if we are to keep meals on the table for generations to come.

Forest-Friendly Fires

In a busy market in the Ugandan capital of Kampala, a group of women gather to cook. While the dishes they prepare are traditional, the brightly coloured stoves they cook on are new.

The locally made Ugastove, which requires on average half the amount of charcoal of traditional cookers, saves money in reduced fuel costs, cuts carbon emissions and reduces deforestation.

Protecting Precious Landscapes

To cope with our growing population we have tripled our exploitation of natural resources in just 40 years. As a result of the vast expansion of mining, industrial-scale farming, fishing and other human activities, natural ecosystems have lost nearly half of their area, and one million plant and animal species are facing extinction. Without the ecological networks which regulate our planet — from cleaning air and water to providing food — we simply cannot survive.

Eco Burials & Protecting The Great Barrier Reef

Green Goodbyes 

Death is a messy business. In America alone, 1.6 million tons of cement and over 870,000 gallons of embalming fluid — commonly containing formaldehyde — are buried along with 2.5 million caskets every year.

“What you have here is a landfill … a toxic landfill,” says Glen Ayers of the Green Burial Committee as he looks around a traditional graveyard in Massachusetts.

Life After Conflict

"earthrise" explores the environmental consequences of war and how different people, from Rohingya refugees to Syrian scientists, are trying to restore a healthy relationship with nature.

 

Survival: Driving Change

China and the United States are the world's two biggest carbon dioxide emitters, but what approach are these countries' governments taking in the fight against climate change?

In Shenzhen, one of China's most populous cities, new regulations to tackle air pollution are helping to unleash a revolution in clean energy and transport. Stephanie Wong visits Shenzhen to learn more about how the city is cleaning up its transport.

Water: Saving Every Drop

Estimates say that by 2030, if we carry on as we are, the world will have only 60 percent of the water it needs. In India's Ladakh, rising temperatures are leading to glacial melt and water shortages in the mountains of the Himalayas. The Hashemite Kingdom of Jordan is also struggling as it experiences severe drought.  

"earthrise" investigates the local solutions being developed in Ladakh and Jordan to help ease the increasingly worrying water problems.
