Urban Planning Professor Anastasia Loukaitou-Sideris spoke to the BBC about the growing trend of parks designed for older adults. Inspired by Chinese parks with machines for gentle stretching and strength training, governments around the world have started building playgrounds to improve health among older populations. Loukaitou-Sideris stressed the importance of accessible design. “Often older adults feel not welcome in parks that are primarily designed for younger populations,” she said. “In other words, parks are not psychologically accessible to them.” After studying park use among older adults across different countries, Loukaitou-Sideris found that “park location, design and amenities most influence use among senior citizens.” Senior playgrounds encourage exercise, social connection and time spent in nature, improving health and effectively reducing the cost of public healthcare. Golden Age Park, the first park designed for seniors in Los Angeles, was created using guidelines set forth in Loukaitou-Sideris’ research and will open Saturday, Nov. 2.
In the face of extreme weather, polluted aquifers, overconsumption and other urgent threats to our water supply, Sandra Postel has reason to hope. The leading authority on water sustainability has traveled the world seeking out fresh strategies to protect an ecosystem that is under attack. “Yes, the water cycle is badly broken,” she told a gathering hosted by UCLA’s Luskin Center for Innovation on Jan. 25. “But through creativity, through innovation, through some interesting ingenuity, a good dose of courage and some risk-taking … we can fix it.” Instead of trying to tame nature, humans would be wiser to respect its rhythms, says Postel, who lays out her case in the new book “Replenish: The Virtuous Cycle of Water and Prosperity.” At the Luskin Innovators Speaker Series event, Postel was joined by a panel of policy experts and entrepreneurs from across Southern California: Eric Hoek, former UCLA professor and co-founder of Water Planet, which develops advanced water filtration systems; Rita Kampalath, program director for L.A. County’s Chief Sustainability Office; and Omar Moghaddam, who has three decades of experience working with wastewater and renewable resources in Los Angeles. The discussion was moderated by Mark Gold, associate vice chancellor of environment and sustainability at UCLA. Postel stressed that collaboration is key to a more secure water future. A national initiative she co-created, Change the Course, draws together business leaders, conservationists and the public to reduce waste and replenish water in the natural world. To date, Change the Course has restored more than 8 billion gallons to depleted rivers and wetlands, earning it the 2017 U.S. Water Prize for creative water management solutions. “Sounds like a big number,” says Postel. “It’s a drop in the bucket, of course, of what’s needed. But it’s made a difference.” — Mary Braswell
