Conoscenze e abilità da conseguire

Students will learn the conceptual foundations to understand the interactions between natural and social systems in globally changing urban landscapes (terrestrial, freshwater and marine), and will gain analytical basic 'urban-ecology tools' to be applied in e.g. urban monitoring, planning and restoration. The students will be introduced to urban areas as 'novel ecosystems', and will learn about the unique ecological conditions and functioning of cities and waterfronts, the environmental challenges and opportunities of a sustainable urban development, and the principles and strategies for biodiversity conservation, restoration and management in a human-modified context. They will be introduced to ecosystem services concepts and how to use them in an interdisciplinary analysis. They will also learn the direct and indirect effects of human impact with a particular attention to freshwater ecosystems as Highly Modified Bodies (WFD 2000/60/CE definition). Students will get the ability to read and understand articles in the field of urban ecology, sustainability and restoration science, to synthesize and communicate interdisciplinary research, and will gain insight about how to identify appropriate solutions to questions relevant to urban planners, policy makers, and managers. Student will also get the opportunity to develop a field-work proposal of restoration project in an highly modified area.

Module Airoldi

Introduction– Principles of urban ecology and the concept of novel urban ecosystems

Unique (man–made) ecological conditions of urban ecosystems– land (and sea) use cover; urban climate and the heat island effect; changes in the physical environment (soil/sediment properties, hydrological processes and (sea)water characteristics); impacts of pollution, noise, artificial light and electromagnetic fields

Patterns of urban biodiversity and controlling factors– impacts of urbanisation on biodiversity and changes in biodiversity along urban-rural gradients; losers and winners in urban habitats, homogenisation and the susceptibility of urban ecosystems to species invasions; effects of altered disturbance regimes; habitat transformation, fragmentation and loss in urban land/sea-scapes, altered connectivity, and dispersal barriers and corridors

Ecosystem functions and services in urban landscapes- urban biodiversity and ecosystem services; valuing the role of natural ecosystems in flood risk reduction and nature-based adaptation; ecosystem management options to enhance resilience of society and the environment to future climate conditions.

Principles of sustainable urban development- urban footprint, sustainability and governance-related challenges in urban environments; natural capital and strategies for biodiversity conservation; indicators of environmental quality in urban environments (e.g. the city biodiversity index, the Ocean health index, etc); management of multiple stressors and stakeholders; bioengineering, multifunctional blue/green infrastructures; conservation and restoration in an urban context

Metodi didattici

Frontal lessons

Discussion groups of hot topic papers

Practical group excercises

One joint field excursion

Modalità di verifica dell'apprendimento

The exam will assess knowledge about the structure and functioning of natural systems (populations, communities, ecosystems). The final evaluation is expressed in 30ies.

There will be 6 exam dates (2 per session). The first exam will be a written test (about 20 -25 open and closed questions), while the remaining 5 dates will be oral exams. The dates of the exams will be posted on the site AlmaEsami. Students can book for the examination exclusively using the procedures provided by the online system Alma Exams (https://almaesami.unibo.it/almaesami/welcome.htm).

 

The exam grade awarded may be refused up to a maximum of two times
