Within WP2, the objective of task 2.1 is to start the development and establish an online facility to collect descriptions/inventories of potential relevant NBS for the trans4num study sites. NBS innovations potentially relevant for the trans4num study sites will be based on internally available documents (deliverables 1.1 and 1.3) and outputs of EU projects, such as Lex4bio, Nutriman etc. The NBS will be characterised with respect to their biophysical, agronomic, and farm management implications at field and farm levels, and they will be assessed and ranked according to their potential for each of the NBS sites in close consultation with respective farmers and related stakeholder groups. The most promising NBS will be selected for field implementation and testing with farmers' participation. Consequently, the inventory starts with a selection of already well-captured NBS and then gradually becomes both deepened in contents and extended in cases. These will be connected to the four NBS sites of the trans4num project. The online inventory will be presented at the trans4num website: htps://trans4num.eu/en/
