The great cities of the world are stepping up to meet the challenge of climate change. Anne Hidalgo, Mayor of Paris and Chair of the C40 Cities Climate Leadership Group Climate change is the greatest threat facing our planet. 


The leaders of the world’s great cities recognize that fact and are taking urgent action. But mayors need strong allies to deliver the transformations needed to create sustainable, green cities of the future. There is no greater partner for our campaign to save the planet than the Global Environment Facility. 


C40 is a network of the world’s megacities commited to addressing climate change. Recent research by the C40 Cities Climate Leadership Group, Deadline 2020, makes clear the urgency of the climate crisis. The scale of the challenge is formidable. Emissions from the 91 C40 cities need to have peaked by 2020 and average per capita emissions need to almost halve by 2030. 


There is no time to waste in order to deliver on the ambition of the Paris Agreement, to keep global temperature rise to below 1.5 degrees Celsius above pre-industrial levels, and therefore avoid catastrophic climate change.

"Achieving the ambition of the Paris Agreement will require $375 billion in investment focused on low carbon infrastructure in C40 cities up to 2020. These investments will transform and improve entire economies by creating jobs, bolstering infrastructure, improving public health and making cities more livable. As a byproduct, they will also help secure our planet for future generations."

Heat from North American cities causing warmer winters, study finds

Heat from North American cities causing warmer winters, study finds | RSE et Développement Durable | Scoop.it

Researchers say extra heat generated by huge cities explains additional warming not explained by existing climate models.

 

Those who wonder why large parts of North America seem to be skipping winter have a new answer in addition to climate change: big city life.

A study, published in the journal Nature Climate Change, found that the heat thrown off by major metropolitan areas on America's east coast caused winter warming across large areas of North America, thousands of miles away from those cities.

 

Scientists have for years been trying to untangle how big cities – with the sprawl of buildings and cars – affect climate. The study suggests cities themselves have far-reaching effects on climate, in addition to the climate pollution caused by the burning of fossil fuels.

Very interesting reading this. It seems quite true since the past winter didn't seem as cold as most winters here in Rhode Island. If the big cities cause the winter to be less cool then in the future, would winter even be cold? Lets hope and say this problem will never happen.

Urban farms won't feed us, but they just might teach us

Urban farms won't feed us, but they just might teach us | RSE et Développement Durable | Scoop.it

It's clear that the craze for the urban farm is no answer to feeding our teeming cities. Its value lies instead in how it can change us.

 

If we want to scale up regional food systems, it seems like it would be a great idea to grow a significant amount of our calories right in our cities. It’s a beautiful concept, reuniting humans and nature to solve many of the problems brought about by our urbanization. But talking to urban farmers and reading the recent research turned a cold hose (of reclaimed rooftop drain water) on my enthusiasm.

There’s a backlash underway against the general exuberance over urban farming, and, surprisingly, it’s coming from urban farmers. It’s a measured, cautious backlash — less pendulum swing than correction...

Urban Farming is not the only solution towards feeding the growing population in cities but it certainly contributes to greater food resilience, habitat and biodiversity in cities. It makes a valuable contribution to local economy and food access which is part of a much bigger picture.

Nueva vuelta de tuerca a un tema relacionado con los techos verdes, asunto que traté recientemente en esta curación de contenidos. 

 

En su artículo, Nathanael Johnson alude a los beneficios que pueden suponer estas granjas o huertos urbanos sobre los ciudadanos, tanto desde el punto de vista de acceso a unos productos de calidad como en relación con el beneficio económico que puede generar en los productores. En relación con esta fuente de ingresos, el autor pone como ejemplo la empresa Lula Farms, proyecto que se inicio en una azotea de Montreal y que actualmente proporciona beneficios estables (http://bit.ly/1qymQyo).

 

Obviamente, son necesarias unas estructuras mínimas tales como una superficie lo suficientemente amplia y plana para que la inversión merezca la pena, siendo igualmente necesaria una estructura sólida que pueda soportar el peso sin problemas. No obstante, también pueden ser viables las conocidas como granjas verticales.
