At Transition Campus, a systemic approach to heat wave

As Europe collects a heat of extreme violence, at Transition Campus as elsewhere the temperature rises leading to a reorganization of practical life. On this place that connects training, research and collective life, sobriety entry questions lifestyles before infrastructure, to address the situation from a systemic point of view. The weather is a common place par excellence. For the formation pole, the reminder of the gravity of the stakes is therefore facilitated by this much more incarnated experience of what the curves which despair many observers attentive to climate projections for decades.

At the level of work, schedules and spaces are adjusted to the extent possible, and the proximity to the Seine allows you to enjoy a bucolic swim. Without air conditioning, the château's cool spaces are as many refuges for part of the collective: the library and woodwork room, which fled in winter, naturally offer luxurious freshness. Collectively, a co-responsibility on opening and closing doors and windows is diffused to optimize natural cooling circuits. Historically, the thermal comfort stakes of the Campus start from a cold-related energy precariousness, with a methodology that activates when the degrees decrease. The technical, ecological and financial imperatives require an adaptation of lifestyles, to heat bodies rather than spaces. From this point of view, the "castle" whose first vocation is to be a summer resort offers a very privileged thermal inertia when it is hot.

But above all, since our seine-et-marnaise rurality a question arises: how can we contribute to the overall adaptation to this disruption? While disseminating practices for buildings as privileged as a former holiday home does not necessarily have a major interest in already documented public policies, this stifling heat requires, above all, an ambitious and urgent direction to focus on maintaining the rivers and rivers of our territories in good condition: we must love them more than ever, to take better care of them. Fortunately, solutions exist and allow for the consideration of co-benefit trajectories for mitigation, adaptation and food sovereignty. Sitting on the throne to reduce the impact of locally produced wheat by 90%? The comparative life cycle analysis between one kg of wheat produced with nitrogen fertilizers and one kg of wheat produced with urino-fertilizing inputs makes this clear. Linking the garden, the layout and the collective life, experiments of the separation of urine at the source are an important axis of action research at the Campus, for several years already. The development of collection, processing and distribution channels requires new economic models, costly investments are needed and socio-technical and regulatory barriers are numerous. Given the importance of such public policies to the territory, economic actors could be mobilized to supplement public investment funds.However, if the love of the Seine can probably make us want to stop peeing in a violin (in this case, drinking water), legal policies of accountability of organizations must innovate. Because on what basis should companies be mobilised, and for what contributions? Organisations' accountability for water, which is probably the most advanced environmental policy with climate, is historically built around the polluter-pays-pays-pays-pays principles. These principles have structural limitations in this case: the separation of urine at source affects diffuse pollution, particularly of farmers and farmers and households. Technically impossible to attribute, managing these impacts first through the empowerment of individuals or farmers are socially controversial approaches. The principle of systemic responsibility and its possible implications for business accounting could then be explored as ways to facilitate the mobilization of resources to meet the challenges, while a citizen's view of the state of the rivers could be mirrored to help weave new forms of territorial responsibility.
