This chapter outlines the aim, scope, and structure of the book. It provides a definition of ‘risky places’ and identifies their importance for crime and feelings of safety. We also introduce the need for new ways to understand the complex dynamics of these places. In this chapter, we justify why we advocate for a systems thinking for preventing crime in risky places. This approach considers the context of risky places and their interconnectedness with the broader urban system and supports a longer-term integrated approach. We emphasize the need for a shift in the analysis and governance of risky places through a systems thinking lens.
