Join Earthwise Aware (EwA) for an interactive walk to observe, document, and take part in shaping urban spaces that work with nature. Together, we will explore how design choices and climate pressures shape the ecological value of our everyday green spaces, and document habitat conditions using simple citizen science tools. Starting at the library lawn, we will examine spaces that appear green but often function poorly. Manicured lawns and sparse tree plantings may look inviting, yet they frequently support little biodiversity and can limit soil health and resilience. What makes a space truly nature-friendly? We will record what is present, what is missing, and what that tells us about ecological function. During the walk, we will: Observe and document plant communities and habitat quality Identify signs of low and high ecological function Compare conventional landscapes with more resilient plantings such as native beds or meadow patches Contribute real data that supports local ecological understanding and decision making This is participatory science in practice. Your observations will feed into broader efforts to track urban biodiversity and inform better land use choices. The program will meet outside the library in Joan Lorentz Park. Registration required. Rain date: Wednesday May 6

Every year, June is proclaimed Month of Portuguese Heritage in Massachusetts. Join us for a free concert at the Main Library in celebration of Portuguese Heritage Month. The concert will feature a jazz quartet performing works by Carlos Paredes and other Portuguese composers. Carlos Paredes (1925 – 2004), the most renowned Portuguese guitar composer, maintained significant artistic dialogues with other musical genres. Amongst his most important collaborations was an album recorded together with jazz musician Charlie Haden. The concert will also be a tribute to Paredes’ work on the 100th anniversary of his birth. The band consists of Tim Pascoal on piano; Gen Yoshimura on Drums; and Youngchae on upright bass. The performance will also feature Francisco Pais Cardoso on Guitar. A reception with Portuguese pastries will follow the concert. This event is cosponsored by the Cambridge Public Library and the Consulate General of Portugal in Boston, with the support of Camoes – Institute for Cooperation and Language (Portugal). Registration is required.

Dr. James Barrett, Director of Clinical Support Services for the Cambridge Police Department, co-authored a study published in JAMA Network Open revealing that one in five U.S. adults who die by suicide had spent at least one night in jail in the year prior. The research highlights the need for community-based suicide prevention efforts, particularly post-release. Dr. Barrett’s work with CPD and the Cambridge Health Alliance focuses on supporting individuals with mental health conditions through case management, follow-up care, and a co-response model that pairs clinicians with officers for mental health-related 911 calls.
