Learning objective: Students plan an urban garden on a limited area, taking into account sustainable principles.
Resources required: Empty yard (e.g. 10 × 10 m), compost bin, rainwater collector, flowers.
Activity procedure:
- Divide students into groups of 3–5.
- Each group receives a plan of an empty yard (e.g. 10 × 10 m).
- They plan: - a vegetable area,
- a space for herbs,
- a flower bed for pollinators,
- a compost bin,
- a rainwater collector,
- paths,
- a resting area.
At the end, they present their solution and justify it.
PA 2: What goes into compost?
Resources required: Cards or pictures of different waste (banana, plastic bottle, eggshells, cardboard, grass, metal can, coffee grounds, meat, newspaper, leaves, etc.)
Activity procedure:
Students classify materials into: - suitable for compost,
- not suitable for compost,
- conditionally suitable.
Then they explain their decisions together.
Extension of the activity: Groups create the ideal sequence of compost layers.
PA 3: Plant disease detective
Resources required: Photos of plants with different damages.
Activity procedure:
Each group is given a photo with the help of which they determine: - what they notice,
- whether it is a disease,

A community garden established in 2009 on abandoned urban land. Plants are grown in mobile containers, raised beds and recycled containers.
The use of recycled materials, container growing, composting, rainwater harvesting, local community involvement and educational workshops have been introduced as good practices.
The results are the revitalization of the degraded area, increased biodiversity and strengthening the social cohesion of the residents.
After the economic crisis in the 1990s, Cuba developed an extensive system of urban agriculture (Organopónicos). Depending on the needs, many good practices have been implemented, such as organic food production, the use of compost, biological plant protection, local supply of residents, and reduced use of artificial fertilizers.
The results were greater food self-sufficiency, less food transportation, and reduced environmental impact.
The largest rooftop farm in the world with more than 2 hectares of green space on the roofs of buildings, where good practices include roof gardens, vegetable production, beekeeping, rainwater harvesting, and composting.
The project results are: dozens of tons of vegetables produced annually, reduction of the urban heat island effect, and retention of rainwater.
The entire city participates in public food growing in parks, schools, train stations, and other public spaces. Community gardens have been created that have enabled free access to food. Schools are also involved in the production, and above all, local volunteering is being strengthened.
Increased nutritional awareness, community empowerment, and local economic development are important results of this project.
It is one of the largest rooftop gardens in Europe. The result of the green roof is the production of vegetables and fruits, beekeeping, rainwater harvesting and urban biodiversity. All this helps to cool the building, reduce the risk of flooding and improve air quality.
The city supports more than a hundred community gardens, the characteristics of which are shared land use, composting, the involvement of the elderly and young and organic farming. In addition to the production of food itself, better social cohesion has emerged, there are more green spaces in the city, and the food produced is also healthier.
Singapore systematically integrates green infrastructure into urban planning. It introduces a number of good practices - green roofs, green facades, vertical gardens, urban orchards and rain gardens. This helps to reduce overheating of the city, improve air quality and increase biodiversity.
Many cities in Slovenia allow residents to rent landscaped gardens for self-sufficiency. The tradition of growing their own food is widespread in Slovenia. Having their own garden is a privilege that city dwellers are especially aware of. It is mostly organized urban gardening, where composting, rational use of water, organized infrastructure and the promotion of local production are taken care of.
The results are greater self-sufficiency, organized green spaces and greater connectivity of residents.
Teaching gardens of Slovenian primary and secondary schools
Many schools (OŠ Trebnje, Grm Novo mesto, Biotechnical Center Naklo, Biotechnical School Maribor) use school gardens as outdoor classrooms. Many good practices also appear in these gardens, which also have an educational role. Students learn composting, preparing raised beds, collecting seeds, growing herbs, and practical learning is at the forefront.
In this way, practical competences are developed, environmental awareness is increased and different subjects are connected.
