Norway's capital has been working to develop its bee population for years. Bees have been dying all over the world at a rapid pace, and it's a phenomenon that has anyone with an investigated interest in nature very worried. That should include everyone who relies on food to live: bees pollinate the vast majority of our crops, and also support pollination and biodiversity in ecosystems everywhere. We need bees, and if we want to keep them around the world has to get a lot more hospitable to them real quick.
In 2015, Oslo officials started their project to build a so-called "bee highway," meaning strategic placement of flowers, meadows, and even potted plants and rooftop gardens across the urban area. The idea is to help the insects migrate, produce and feed as regularly as possible so they wouldn't become tired and die off due to the stress of searching for food in a city. Government, private businesses, and even regular citizens joined the efforts to save bees in and around Oslo.
Two years later, The Guardian followed up on the growth of the program. City planning has been widely influenced by the project to rescue bees. The city's municipal government has established more than 10 meadows, and support workshops taught by botanists on scything and planting the bee zones. Lawns are being replaced with local grasses and wildflowers to feed the pollinators. A local NGO is even encouraging people to keep hives on their rooftops and in their backyards.
Vice-mayor Lan Marie Nguyen Berg told reporters that Oslo wants to share what they've learned while establishing these projects with other cities, saying it's an important part of a city's growth.
“We know that we need to protect and restore biodiversity even as we build new homes. In a city that is growing fast, it’s also important to make it nice to live. That means good quality green areas,” said Nguyen Berg. “We’d like to transfer the knowledge that we have to other cities.”
There's an importance to the green spaces being meadows rather than lawns. Recent studies show that industrialized agriculture has almost wiped out regular meadows full of different kinds of flowers and food for insects in nearby Denmark, and Britain has also seen a decline. Oslo's list of endangered species are dependent on the growth of meadows—24% of them are dependent on that form of ecosystem. Biologist Anna Blix told The Guardian that people don't realize many endangered animals are much smaller than what we ordinarily picture when we consider at-risk species.
“Oslo can be considered a model because we know what’s there and how to protect it,” she said. “We don’t have huge endangered mammals in meadows, but there are many important plants and insects that are at risk.”
Developing the insect corridor or "highway" is also relatively inexpensive. Though the soil needs to be cultivated and monitored for best growing practices, most of the flowers that support wildlife are technically weed. They're all also local to the area, so once planted, they tend to thrive. That's what happens when a good idea gets planted.
To keep rare bat species in an area where they thrive, a community that's already created nearly 100 sustainable homes is changing their street lights. These new red LED bulbs will allow humans to continue operating at night while the bats can avoid it.
Mountain gorillas remain an endangered species, but conservation efforts such as regulated tourism and habitat protection has increased their population over the last 35 years. It's jumped 25 percent in a specific African region in the past eight years.
China continues to deal with rising population in their cities, and that includes immigration from other regions of the country. To promote local food growth, 1,000 "Slow Food" villages will be created in an effort to educate those on culture and sustainability.
One of the biggest databases of pollution that's been picked up off the streets has been upgraded to make the experience easier. Litterati, downloadable on iOS and Android devices, now allows for better collaboration, advanced tagging, and easier photo uploads.
