Green eco-cities of the future (and present) by Moira Stemp https://padlet.com/stempmoira/ecocities Different ides for creating sustainable cities that respect our environment. en-us 2023-01-25 08:25:44 UTC 2025-09-26 15:33:54 UTC hello@padlet.com stempmoira https://padlet.com/stempmoira/ecocities/wish/2455847294 The Power of Moss
The unique characteristics of moss make it incredibly suited for green façades. With rhizoids instead of roots moss is non-invasive to the façade and with its dense leaf system it provides many wonderful benefits to the urban environment:

  • Contaminant reduction: 
Moss converts CO2 to oxygen and absorbs and removes other pollutants such as PM10, VOCs, NOx, and NH3, from water and air.

  • Water retention:
Moss can absorb and retain large amounts of water in its leaf system.

  • Cooling: 
Through evapotranspiration and shielding of the surface from sunlight moss attributes to cooling of the structure.

  • Biodiversity: 
Moss increases local biodiversity by providing habitat for vital fauna on otherwise bare concrete surfaces.

  • Noise reduction:
With its dense leaf system moss captures sound and reduces noise pollution.

  • Aesthetically pleasing:
Coordinated moss growth turns bare concrete structures into  beautiful sights.

  • Biomass production:
Moss produces biomass which is a suitable renewable resource for other products.

Until recent years, Singapore has been dependent on its neighbours for imports of food supplies to feed its growing population. 90% of Singapore's food comes from abroad and only 1% of land is used for conventional agriculture. 

Closed borders during Covid lockdowns put increased pressure on this supply, highlighted Singapore's vulnerability and increased efforts to provide enough food internally and to guarantee Singapore's food security. 

Singapore is aiming to produce 30% of its own food by 2030, currently it is producing around 10%.

To achieve this, emphasis has been put on citizens to help grow what they can.

Growing food in urban farms on carpark rooftops or reused outdoor spaces and retrofitted building interiors is key to the '30 by 30' goal.

Hydroponics: still requires fresh water for growth. 
Internal vertical farms: require water and electricity. 
Fish farms: are subject to tidal surges and pollution.
External rooftop and vertical farms: are at risk of high winds during potential tropical cyclones.]]> 2023-01-25 11:00:46 UTC https://padlet.com/stempmoira/ecocities/wish/2455981449 stempmoira https://padlet.com/stempmoira/ecocities/wish/2455983641 2023-01-25 11:03:12 UTC https://padlet.com/stempmoira/ecocities/wish/2455983641 The Limits of our Urban Model stempmoira https://padlet.com/stempmoira/ecocities/wish/2455991278 In 1812 just 2% of the global population (approx. 1 billion people) lived in urban areas.
 
In 2023 around 50% of the global population (approx. 8 billion people) live in urban areas. 

Cities are noisy, dirty, over-populated and polluted. 

Extreme wealth and extreme poverty live side-by-side.

Global warming, reduced fossil fuels and a continually rising population, mean we need to rethink our urban model.]]> 2023-01-25 11:10:49 UTC https://padlet.com/stempmoira/ecocities/wish/2455991278 The Goal of an Eco-city stempmoira https://padlet.com/stempmoira/ecocities/wish/2456003319 The goal of an eco-city is to reduce the city's impact on our environment.

The main challenges are:
- growth of population centres
- energy consumption
- recycling
- the new urban landscape
- social diversity

We need to:
- transform the buildings we live in
- change our modes of transport
- implement new ways of supplying electricity

from outdoor air pollution could be avoided.
 
 The social costs of transport include road
crashes, air pollution, physical inactivity, time taken away from the family while commuting and vulnerability to fuel price increases. Many of these negative impacts fall
disproportionately on those social groups who are also least likely to own and
drive cars.

Traffic congestion imposes economic costs by wasting people's time and
by slowing the delivery of goods and services. Traditional transport planning aims to improve mobility,
especially for vehicles, and may fail to adequately consider wider impacts. But
the real purpose of transport is access – to work, education, goods and
services, friends and family – and there are proven techniques to improve access
while simultaneously reducing environmental and social impacts, and managing traffic congestion.
