Targeting Audiences for Improved Lawn Management: Can Grouping Households Assist with Nonpoint Water Pollution Reduction
In urban ecosystems, households are important decision-making units that are resource consumers and contributors to urban water pollution. At the landscape level, individual household choices regarding lawn management vary greatly, contributing to the detriment or protection of water resources. To …
