Néstor Colman, 69, remembers the river overflowing its banks nine times in Bañado Sur, the poor neighourhood in the Paraguayan capital where he was born and has lived all his life. “A record,” he jokes.
Three decades of dengue fever epidemic did not manage to awaken a sense of urgency in Brazil regarding the need for improving and expanding basic sanitation. But the recent surge in cases of microcephaly in newborns, associated with the Zika virus, apparently has.
Brazil is deploying 220,000 troops to wage war against the Zika virus, in response to the alarm caused by the birth of thousands of children with abnormally small heads. But eradicating the Aedes aegypti mosquito requires battles on many fronts, including science and the pharmaceutical industry.
Rubbish covers the beaches and clutters the rivers, the garbage dump is not properly managed, and more than 100 factories spew toxic fumes into the air in the city of Bajos de Haina, a major industrial hub and port city in the Dominican Republic.
River port terminals in the northern Brazilian city of Santarém are considered strategic by the government. But what some see as an opportunity for development is for others an irreversible change in what was previously a well-preserved part of the Amazon rainforest.
“That law should have existed since the end of slavery, which threw slaves into the street without offering them adequate conditions for working and producing, turning them into semi-slaves,” said Brazilian farmer Idevan Correa.
Itaboraí still recalls its origins as a sprawling city that sprang up along a highway, not far from Rio de Janeiro. But a few years ago big modern buildings began to sprout all over this city in southeast Brazil, whose offices and shops are almost all empty today.
The hands of women who have migrated from rural areas carefully tend to their ecological vegetable gardens in the yards of their humble homes on the outskirts of Sucre, the official capital of Bolivia, in an effort to improve their families’ diets and incomes.
Children have been poisoned by lead in Villa Inflamable, a shantytown on the south side of the capital of Argentina. Resettling their families involves a socioenvironmental process as complex as the sanitation works in one of the most polluted river basins in the world.
The inhabitants of the northern Chilean mining region of Antofagasta have the highest per capita income in the country. But some 4,000 local families continue to live in slums - a reflection of one of the most marked situations of inequality in this country.
Slums are a curse and blessing in fast urbanising Africa. They have challenged Africa's progress towards better living and working spaces but they also provide shelter for the swelling populations seeking a life in cities.
During a women’s football match in a poor neighbourhood in Buenos Aires, team manager Mónica Santino has to stop the game and ask a group of boys and young men not to invade the pitch where they’re playing. This frequent occurrence is just one symbol of a struggle being played out, centimeter by centimeter, on Argentina’s pitches.
With cities increasingly in the spotlight on the international stage, urban planning and development has become a critical issue in the Sustainable Development Goals (SDGs).
How can we provide healthy food for everyone, without threatening the survival of our planet? This is the fundamental issue at the centre of Expo 2015 – which has ‘Feeding the Planet, Energy for Life’ as its central theme – and a huge challenge for cities.
There's little argument about the basic facts: It's ugly (think strip malls and big box stores). It's not very convenient (hours spent behind the wheel to get to work). And it wreaks havoc on the natural environment (lost farmland and compromised watersheds).
