“…This disparity appears particularly strongly when it comes to individuals’ participation: time and space have a significant impact on who is participating in IO undertakings, de facto leaving aside some actors who cannot afford long‐haul travels or expensive rents (Dairon & Badache, this special issue; Kimber & Maertens, this special issue), or on the contrary allowing others to join (Eckl, this special issue). A less expected repercussion lies with the success of local actors in trying to capitalize on the role of time and space: while they may sometimes gain political power and concrete influence on IOs (Campos, this special issue; Dairon & Badache, this special issue), they can also be marginalized compared to distant stakeholders, such as donors and IOs’ headquarters, which succeed in imposing their rules at a distance (Verlin, this special issue). At the level of institutions, the spatiotemporal ecosystems can affect the performance and legitimacy of IOs, potentially bringing benefits and economies of scale, or being translated into cumbersome procedures or tensions between different departments, divisions or working groups over how to perform certain tasks (Dairon & Badache, this special issue; De Pryck, this special issue; Worrall, this special issue).…”
