Zagreb i-team Focus Challenges
The Zagreb i-team is concentrating on 2 focus areas right now. Read what we are looking for, or submit a general idea on any other topic.
Challenge 1
Addressing heat stress and heat urban islands
Reducing heat stress and cooling Zagreb's hottest neighbourhoods.
Zagreb faces growing heat stress — especially in summer, when dense urban areas become heat islands: pavement, rooftops, and limited tree cover trap warmth and make some neighbourhoods noticeably hotter than others. We want practical ideas to reduce heat stress, cool public space, and protect residents during heatwaves.
Why it matters
Heat stress affects health, productivity, and quality of life — particularly for older people, children, and outdoor workers. Urban heat islands are not evenly spread: small, targeted changes — more shade, greener courtyards, smarter surfaces — can make a real difference street by street.
What we are looking for
Low-cost interventions that could be tried in one street or neighbourhood
Ideas that combine green space, shade, or water with existing city maintenance
Suggestions for how the city could prioritise the areas under greatest heat stress
Ways to involve residents, schools, or local businesses
Your own experience counts. We are looking for ideas worth exploring, not polished proposals.
Regular actions by city offices and community boards that connect neighbourhoods.
The i-team is helping the City administration identify practical actions that city offices, departments, and community boards can implement on an ongoing basis — not one-off events, but things that become part of how neighbourhoods work. The aim is to bring residents and foreigners closer together and give foreigners real ways to take part in local life.
Why it matters
When foreigners can participate in neighbourhood life — through community boards, local programmes, or everyday contact with city services — attitudes shift. Residents and newcomers build familiarity and trust with one another. That mutual trust is the outcome we are working towards, and it grows from repeated, visible actions at the level of offices and local communities.
What we are looking for
Actions that city offices or departments could run regularly to connect residents and foreigners
Ideas community boards (mjesni odbori) could adopt to involve foreigners in neighbourhood life
Low-effort, repeatable programmes — not one-off campaigns — that build familiarity over time
Examples from other cities or neighbourhoods that could be adapted for Zagreb
Suggestions for how the i-team and administration could package these as a toolkit for offices and boards
Your own experience counts. We are looking for ideas worth exploring, not polished proposals.
