Traditionally, it has been considered that cultivating food causes biodiversity loss and has a negative influence on an ecosystem. A new study from various colleges, including The University of Texas at Austin, contradicts this idea, demonstrating that community gardens and urban farms benefit biodiversity, local ecosystems, and the well-being of the people who labour in them.The study, published in Ecology Letters, looked at 28 urban community gardens across California over five years and quantified biodiversity in plant and animal life, as well as ecosystem functions such as pollination, carbon sequestration, food production, pest control and human well-being."We wanted to determine if there were any tradeoffs in terms of biodiversity or impacts on ecosystem function," said Shalene Jha, an associate professor of integrative biology who was lead author on the paper. "What we found is that these gardens, which are providing tremendous nutritional resources and increasing well-being for gardeners, are also supporting incredibly high levels of plant and animal biodiversity. It's a win-win."Previous assumptions by scientists about the negative effect of food production on biodiversity have been almost entirely based on intensive rural agriculture enterprises that tend to grow only one or two types of crops, often at a massive scale. Urban community gardens, private gardens, and urban farms and orchards tend to grow more types of plants in smaller areas. This new study is the first to explore the effects of urban gardens across a wide range of biodiversity measures and ecological services."It's estimated that by 2030, about 60% of the world's population will live in cities," Jha said. "And urban farms and gardens currently provide about 15%-20% of our food supply, so they are essential in addressing food inequality challenges. What we're seeing is that urban gardens present a critical opportunity to both support biodiversity and local food production."The study also found that the choices that gardeners make can have a large impact on their local ecosystem. For instance, planting trees outside crop beds could increase carbon sequestration without limiting pollinators or decreasing food production from too much shade. And mulching only within crop beds could help improve soil carbon services, while avoiding negative effects on pest control and pollinators.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
