With links in the article to Discovery News, Future Science, and a press release from the University of Washington and self-explanatory graphs, it seems that there is not much information that Mrs Green needs to add here.
A quote to take away: The authors propose ” growing wood as fast as possible, harvesting before tree growth begins to taper off and using the wood in place of products that are most fossil-fuel intensive.”
In a mountainous area of South Africa’s Limpopo Province, water is harvested from fog-bearing winds.
The Tshiavha Primary School, with the aid of Liesel Dyson and researchers from the University of Pretoria and the University of South Africa, has built a six-metre high net that traps 2,500 litres of water per day. Tshiavha’s elevation faces the fog-bearing winds off the Indian Ocean which is several hundred kilometres away.
Three six-metre-high wooden poles are set up nine metres apart, and water drops are caught by a double layer of 30 percent shade cloth draped over steel cables that are stretched horizontally between the poles. The water is collected in a gutter than runs along the bottom of the shade cloth and this channels the water into a storage tank. Read more about it here.
Paris has been a pesticide-free zone for 10 years. There are over 400 bee hives in the city.
It seems that these urban bees are very happy indeed. They have a far lower death-rate (3 – 5%) than their country cousins (30 – 40%). Their honey yield is almost double. Biodiversity also has a role to play – urban honey made in Paris contained more than 250 different pollens. Honey from the French countryside can contain as few as 15 or 20 pollens. Sweet stuff …
