Water-Efficient Landscaping and Use of Drought-Tolerant Plants

Atatürk University applies a comprehensive water-smart landscape management policy to reduce irrigation demand and promote ecological balance across its 4,000,000 m² campus area in Erzurum — one of Türkiye’s coldest and driest high-altitude cities.
The university’s Sustainability and Infrastructure Units, in collaboration with the Faculty of Agriculture and the Environmental Engineering Department, design all green areas according to low-water-use landscape standards, incorporating drought-resistant native flora and advanced irrigation technologies.


1. Climate Context and Landscape Design Approach

Erzurum’s continental climate — characterized by long, snowy winters, short summers, and low annual precipitation (~430 mm) — necessitates the use of hardy, drought-tolerant, and frost-resistant vegetation.
Atatürk University’s landscape strategy emphasizes:

  • The selection of native and cold-resistant species,

  • The use of minimal irrigation zones and soil moisture monitoring,

  • The integration of organic mulch and permeable soil designs to retain water,

  • The prioritization of perennial species over annual ornamentals,

  • The avoidance of water-demanding turfgrass lawns except for limited recreational areas.


2. Drought-Tolerant and Cold-Resistant Plant Species Used

The university’s green spaces are designed with a diverse mix of indigenous and adaptive species that require minimal irrigation once established. Examples include:

Plant Category Species (Scientific Name) Common / Local Name Water Demand Climate Suitability
Coniferous Trees Juniperus communis, Picea orientalis, Pinus sylvestris, Abies nordmanniana Juniper, Oriental Spruce, Scots Pine, Caucasian Fir Low High frost tolerance (-30 °C)
Deciduous Trees Betula pendula, Acer platanoides, Populus tremula, Ulmus glabra Birch, Norway Maple, Aspen, Elm Medium-low Hardy to cold climates
Shrubs & Bushes Berberis thunbergii, Spiraea crenata, Rosa canina, Viburnum opulus Barberry, Spirea, Wild Rose, Viburnum Low Native to Eastern Anatolia
Groundcovers & Perennials Festuca ovina, Sedum acre, Achillea millefolium, Artemisia absinthium Sheep Fescue, Stonecrop, Yarrow, Wormwood Very low Survive dry and cold soils
Flowering Species Iris sibirica, Tulipa armena, Viola tricolor Siberian Iris, Armenian Tulip, Wild Violet Low Short-bloom, frost-tolerant

These species were selected based on their native origin, low evapotranspiration rates, and proven adaptation to Erzurum’s semi-arid, high-elevation environment (1,850 m).


3. Green Space Composition and Water Efficiency

Atatürk University’s current landscape composition (as of 2024) reflects a strong emphasis on sustainable vegetation and efficient irrigation:

Landscape Type Area (m²) Average Annual Water Use (liters/m²) Planting Style Efficiency Practice
Tree-covered green zones 1,200,000 40 Native conifers and deciduous trees Mulching, deep watering only twice a month
Shrub/flower beds 300,000 30 Native perennials and shrubs Drip irrigation system
Turfgrass & recreational fields 150,000 100 Limited to sports facilities Smart irrigation scheduling
Xeriscape & rock gardens 200,000 10 Drought-tolerant species No regular irrigation
Total landscaped area 1,850,000 m²

4. Sustainable Irrigation and Maintenance Systems

  • Drip Irrigation and Moisture Sensors:
    All new landscape developments use drip irrigation systems integrated with soil moisture sensors and weather-based controllers. Irrigation occurs only when soil humidity drops below 25 %, reducing water use by up to 45 % compared to traditional sprinklers.

  • Rainwater Harvesting for Irrigation:
    Collected rainwater from building rooftops is stored in underground cisterns and used for irrigating trees and green corridors during summer months.

  • Mulching and Soil Retention Practices:
    Layers of organic mulch, pine bark, and gravel are applied around plants to minimize evaporation and suppress weed growth, improving water retention in the soil.

  • Winter Protection Strategy:
    For frost-prone months (November–March), irrigation systems are shut off, and plants enter a natural dormancy cycle, reducing water needs to nearly zero.


5. Biodiversity and Ecological Benefits

The use of native and drought-resistant plants supports local biodiversity while conserving water. These landscapes provide habitats for regional bird species (e.g., Carduelis carduelis, Turdus merula), pollinators (e.g., honey bees, wild butterflies), and small mammals.
Through this approach, Atatürk University combines water conservation, ecological balance, and visual sustainability, aligning with SDG 6.3 and SDG 15 (Life on Land).


6. Tree Plantation and Greening Statistics (2024)

Plant Type Number of Trees / Plants Percentage of Total Green Stock
Coniferous Trees (Pinus, Abies, Juniperus) 15,000 45 %
Deciduous Trees (Acer, Betula, Populus, Ulmus) 9,500 28 %
Shrubs and Bushes (Rosa, Berberis, Spiraea) 6,800 20 %
Groundcovers and Perennials (Festuca, Sedum, Achillea) 2,700 7 %
Total 34,000+ living plants 100 %

Tree-planting activities are carried out annually in cooperation with the Environmental Application and Research Center (Çevre Uygulama ve Araştırma Merkezi), contributing to carbon sequestration and ecosystem resilience.
