The activity is proposed to the two curricula of the Master in Urban and Regional Planning and is related some on site applied experiences aimed at enriching the wide field of competences on planning and design cultures in order to face contemporary challenges. The activity in this field can change. In A.Y. 2023/24 the LM 48 proposes a Workshop "Planning for biodiversity". BACKGROUND Biodiversity is gaining growing interest in numerous disciplinary domains and is becoming central to the international debate on sustainable design and planning. In England, this rise of interest has been further triggered by a new mandatory requirement, introduced by the Environmental Act in 2021. In compliance with this Act, planning applications will need to demonstrate that post-development, the natural environment will be better than it was beforehand, by ensuring a 10% biodiversity increase as a minimum. In these statutory terms, the concept of Biodiversity Net Gain (BNG) has become a ground-breaking approach to land management and development aimed at achieving measurable betterment and will become mandatory for obtaining planning permissions in England after being incorporated in the Town and Planning Country Act. Further details of this new legal framework entail securing habitat for 30 years as a minimum, via obligations/conservation covenants; habitat to be delivered either on site or off site via biodiversity credits; and creating a national register for biodiversity credits. AIM The aim of this seminar is to explore the concept of biodiversity and its implementation in the UK context, and to apply this knowledge to chosen case studies in the Turin area.
