6.3.5
Water-Conscious Planting Policy
The University of Thessaly (UTh) recognizes the critical role of responsible landscaping and vegetation management in achieving sustainable water use and biodiversity conservation.
This policy establishes principles and guidelines for water-efficient planting and landscape design across all University campuses and facilities.
Purpose
This policy aims to:
Promote the use of native and drought-resistant plant species that require minimal irrigation.
Reduce water consumption in landscape maintenance through efficient design and technology.
Prevent soil erosion and water runoff, protecting natural ecosystems.
Enhance campus biodiversity, aesthetics, and resilience under changing climate conditions.
Support the implementation of SDG 6, SDG 11, SDG 12, and SDG 15.
Legal and Technical Framework
This policy aligns with:
Law 1650/1986 and Law 4042/2012 on environmental protection and sustainable resource use,
Law 3199/2003 and P.D. 51/2007 transposing Directive 2000/60/EC (EU Water Framework Directive),
Law 4067/2012 (Building Regulation – sustainable infrastructure provisions),
EU Biodiversity Strategy for 2030, and
The University of Thessaly Environmental Sustainability Plan.
Scope
This policy applies to:
All University campuses, research farms, botanical gardens, and open spaces,
New landscaping projects, renovations, and maintenance operations,
All staff, contractors, and project designers responsible for landscape design and irrigation management.
Key Provisions
- Selection of Plant Species
Preference shall be given to indigenous, drought-tolerant, and low-maintenance plant species suitable for the Thessalian climate.
The use of non-native or high-water-demand species is discouraged except for educational or research purposes.
The Department of Agriculture, Crop Production and Rural Environment shall provide guidance on sustainable plant selection.
- Efficient Irrigation Systems
All irrigation systems must employ drip or micro-spray technology and smart controllers that adjust water delivery based on weather conditions.
Rainwater harvesting and greywater reuse systems are to be integrated where feasible.
Overhead sprinklers shall be avoided in favor of targeted irrigation methods to minimize evaporation and water loss.
- Soil and Mulching Practices
Landscapes must include soil improvement and mulching techniques to retain moisture and reduce irrigation needs.
Organic mulch and compost should be used to enhance soil health and limit weed growth.
Construction projects must protect existing topsoil and natural vegetation whenever possible.
- Design and Maintenance
Landscape designs should group plants by similar water needs (“hydrozoning”) for optimal irrigation efficiency.
Maintenance practices must prioritize minimal water use, seasonal adjustment of watering schedules, and prompt repair of leaks.
The use of potable water for irrigation should be minimized; treated or reclaimed water is preferred.
- Education, Research, and Engagement
The University will support educational programs and research on sustainable landscaping, agroecology, and climate-adapted planting.
Students from agricultural and environmental departments will participate in demonstration projects and training.
Public outreach activities will promote water-conscious gardening among the local community.
- Monitoring and Reporting
The Technical Services Department shall monitor water consumption for landscape irrigation.
Annual reports will include data on irrigation efficiency, native species coverage, and water savings achieved.
Governance
Responsible Authority: Rector.
Operational Oversight: Technical Services Department.
Scientific Support: Department of Agriculture, Crop Production and Rural Environment.
Review
This policy will be reviewed every three years, or sooner if new environmental legislation or climate data necessitate updates.
Through this policy, the University of Thessaly reaffirms its commitment to sustainable landscape management, water conservation, and biodiversity protection across all its campuses.
