The study assesses the 'Rohejälg' project in Tallinn, focusing on how temporary spatial interventions affect public space usage. At Raekoja Square, a temporary park successfully democratized the area by providing a non-commercial resting space, though it lacked shade and water. In the Linnahall area, interventions like new benches and a community sauna improved accessibility and user experience, although the region remains heavily car-centric. The report concludes that tactical urbanism is an effective tool for testing sustainable, human-centric urban design before implementing permanent changes.

The document examines the slow adoption of cleaner cookstoves in peri-urban Kenya, arguing that a combination of service design, behavioral insights, and social-ecological systems thinking is necessary to better align stove development with user needs. Based on a study of advanced biomass pellet cookstoves near Nairobi, it recommends tailoring interventions to specific user archetypes, stabilizing the biomass pellet fuel supply chain through subsidies, and establishing localized technical support and repair networks.

The study found that EPCs significantly displaced charcoal use, particularly for breakfast, and reduced mean charcoal consumption per capita per event by 30%. While the overall daily cost of cooking remained stable at approximately RWF 388 (USD 0.34), users experienced a median meal preparation time saving of 14 minutes. Most participants preferred monthly payment plans and reported high satisfaction, though the limitation of having only one cooking pot was a primary challenge.
