This study aimed to assess the benefits of an agroecological requalification of a dismissed peri-urban area in the South Milan Agricultural Regional Park, Italy. Using I-Tree Eco software, the provision of ecosystem services from planting new hedgerows was simulated over 30 years, showing that the planted area becomes an essential supplier of regulating ecosystem services for neighborhoods, increasing carbon storage and air pollution removal. A notable increase in carbon sequestration was observed at the end of the simulation, demonstrating a replicable methodology and techniques for assessing ecosystem services in urban and peri-urban environments.

A comparative study analyzed the use and development of allotment gardens (AGs) in Westphalia and Lippe (Germany) and Wielkopolska (Poland). AGs in Westphalia and Lippe are accessible and harmoniously integrated into the landscape, while AGs in Wielkopolska are less accessible, prioritize internal users, and do not always blend with their surroundings. The considerable freedom enjoyed by Polish plot-holders leads to a gradual marginalization of edible-plant growing.

This research developed a holistic method and map-based indices for interpreting and classifying peri-urban landscapes, focusing on open spaces to understand their complexity and identify homogeneous units. The method was applied to the peri-urban area of Turin, Italy, generating maps of spatial and functional classification at the landscape unit level, as well as a map of critical areas for improvement. Despite some minor limitations, the proposed method and tools appear to have a range of applications in the context of global challenges and from a landscape perspective.

This study addresses knowledge gaps in selecting plant species and understanding landscape heterogeneity's role in dispersal success for Green Infrastructure (GI) planning. It suggests a methodological approach for fine-scale assessment in peri-urban agricultural landscapes, using a case study in the Metropolitan City of Rome. The approach involved stratifying the area, defining GI components, characterizing the area with Morphological Spatial Pattern Analysis, assessing connectivity, and prioritizing conservation measures. Despite recognized limits, the approach proved functional for the context and detail level.

Research with first-year preschoolers in Spain analyzed their ability to observe, compare, classify, and identify small animals using magnifying glasses and dichotomous keys. Students learned to observe intentionally with magnifying glasses and compare small animals based on the number of wings, legs, and color. However, students struggled to use dichotomous keys, indicating that teacher assistance was necessary to develop scientific skills such as observation, comparison, classification, and identification.

This research, conducted by the Science Shop of Wageningen University and Research, estimated the monetary value of ecosystem services in the Lutkemeerpolder, Amsterdam, which is slated for conversion into a business park. The study identified food production, air purification, recreation, and the effect of greenery on housing prices as key services, valuing them at 1.5 to 8.6 million euros per year. These ecosystem service values were not considered in the original decision-making twenty years ago, leading to a recommendation to reconsider the development plan.

This study compared perceptions of urban agriculture (UA) ecosystem services (ESs) among different societal groups in Bologna, Italy, namely UA project leaders, stakeholders, and the general public, with 406 individuals evaluating 25 ESs via a standardized Likert-scale survey. Statistical analysis indicated that the general public and UA stakeholders agreed on the high relevance of socio-cultural ESs, while provisioning ESs were considered less significant. This study reveals a lower perception of provisioning ESs from urban agriculture.

Allotment gardening (AGs) in Europe, including Poland, is a tradition stemming from rapid urban industrialization, now emphasizing community, social, ecological, creative, and entertainment functions beyond economic and recreational roles. The Polish Allotment Association undertakes numerous initiatives, such as the "Open Social Programme of Allotment Gardens Development," to protect AGs from liquidation and promote their use for public and non-public purposes. This program redefines the perception of AGs in Poland and contributes to their infrastructural development.

This chapter examines a school garden with farm elements at a primary school in a deprived market town in the midlands of England, established as part of an 'eco-school' initiative driven by the former head teacher. The garden included various spaces like a farm, raised beds, a pond, and a herb garden, used for science learning and natural exploration. However, the study notes that the impetus for outdoor learning diminished after the initiating head teacher departed, as school priorities shifted due to other pressures.

This study developed a spatial multi-criteria screening tool in Barcelona, Spain, to prioritize green roof locations and designs for optimal ecosystem service provision. Fifteen spatial indicators and five green roof designs were analyzed and weighted by local experts. The assessment found high demand for green roof ecosystem services across Barcelona, especially in dense residential and industrial areas, with habitat, pollination, and thermal regulation being most needed, while runoff control and food production were least demanded. Naturalized roofs offered the highest potential for 87.5% of rooftop area.
