*Adaptive living and farming techniques for flooding and rising sea levels
#3 & 4:
Gaibandha District. 2010. Villagers moving a floating garden closer to their home. This is an innovative type of agriculture that requires no extra fertilizer or earth apart from the ubiquitous waterbased hyacinth weed. Organized by the NGO Practical Action, villagers pile up the ubiquitous hyacinth weed,to make a floating garden, a freefloating and flood-proof way to grow crops.
Sathkira District. 2010. In the saline and floodprone south of the country, farmers have converted waterlogged rice fields into ponds for salt-tolerant shrimps and crabs.
Flying in the 20s had to be a thrilling experience, indeed. In the absence of radio communication or radar technology, pilots engaged in American coast to coast airmail or passenger service had to rely on often imprecise navigation charts to avoid getting lost. Most of the time they were alone in the air, flying on desertic territory, hoping to reach the destination without encountering bad weather.
To help guiding the pilots across the impervious North American territory, the Congress funded the construction of very large arrow-shaped Airmail Beacons, (up to 20 meters in lenght). Every concrete arrow, painted in bright yellow, was accompanied by a 15 m tall tower, emitting a powerful gas powered light. Each arrow pointed towards the next, separated one with another by a distance of 3 to 10 miles. The beacon towers have been scrapped and recycled for WWII, while the yellow paint has since been worn off by the elements, but the enormous solid concrete arrows are likely to stand there for good.
