There is increasing interplay between humans and artificial intelligent (AI) entities in online environments. With the growing autonomy and sophistication of these AI systems, the hybrid communities which are formed start to behave like the more-familiar, human-only social systems. This sets up the challenge to find systematic ways to ensure reliable governance for these interactions just as we do in human communities. This article proposes a novel approach to build governance for hybrid communities using what we call Conscientious Design (CD). There are two key aspects to CD: 1) the introduction of value categories that guides the identification of relevant stakeholder values, coupled with 2) a tripartite model for online institutions that serves to describe the interactions of hybrid communities of humans and artificial entities in a way that is consistent with the values of all stakeholders.

Of all the uses of water, agriculture is the one that requires the greatest proportion of resources worldwide. Consequently, it is a salient subject for environmental policy-making, and adoption of modern irrigation systems is a key means to improve water use e iciency. In this paper we present an agent-based model of the adoption process-known as "modernisation"-of a community constituted by farmer agents. The phenomenon is approached as a contingent innovation adoption: a first stage to reach a collective agreement followed by an individual adoption decision. The model is based on historical data from two Spanish irrigation communities during the period-. Results suggest that individual profits and farm extension (as proxy of social influence) are suitable assumptions when modelling the modernisation of communities in regions where agriculture is strongly market-oriented and water is scarce. These encouraging results point towards the interest of more sophisticated socio-cognitive modelling within a more realistic socio-hydrologic context.
