B. I Concentrate below on the Resources-Planetary Health Approach, a Social-Ecological Framework
Here are three concepts that mobilize essential methodological instruments within the socioecological approach. Taken together, the elaborated system has systemic transformative potential.
This approach illustrates the work carried out at the Michel Serres Institute, École Normale Supérieure (ENS) de Lyon. It is mainly inspired or reinforced by Michel Serres’ Natural Contract, Elinor Ostrom’s work on resource governance systems and the Resources Management Act 1991, the supreme law of New Zealand. To this must be added new work on carrying capacity, the HANDY model (Mote et al, 2020) and the 2022 report "Earth for All – A Survival Guide for Humanity" of the Club of Rome (Dixson-Declève et al, 2022).
Resources as a social construction of socioecological systems evolve with the cultures, organization and techniques of societies. The physical resources resulting from the cycles and functions of the Earth system are finite or exhaustible and represent the nutrients of social "ecosystems". The dynamics of this socioecological whole are translated into states of health of environments, societies and people. They are inseparable. This is why the “systemic health - resources” approach aims at socioecological robustness as a radical change in the relationships between humans and between humans and nature.

Humans do not frame resources properly, illustrated by predatory economic practices and poor governance across sectors and institutions. The consequence is convergence of cumulative social and planetary crises translating into state shifts defining the 2025-2030 time boundary.

The central role of resource stewardship, according to nature’s physical limits, is highlighted in the context of the boundary systems for the biosphere and societies, and the carrying capacity and inclusive systemic health (One Health, Planetary Health, …). The prioritization of resource justice and responsibility becomes a societal project, embedding the economy in social and ecological frames through institutional reframing. This is supported by assessing the costs of implementation against the cost saving generated by planetary health improvements.
Practicing with resources-planetary health : the ecosystem capital health

This article seeks to categorize a range of environmental evaluation approaches wherein scholars have endeavored to encapsulate GDP within ecological limits of varying strictness. The primary objectives are to delineate their scope, compare them, and address the overarching question : Can current methodologies effectively guide decision-making processes with an ecosystem-based perspective, aiming for "no net ecosystem degradation" ?

The current inclusive health landscape
It consists of frameworks known as One Health, Ecohealth, Planetary Health, or Global Health. One Health and Planetary Health stand out as two competing programs in science, economy, and policy areas developed in the last decade.
Both One Health and Planetary Health present themselves as holistic and systems-based approaches, allign with SDGs and climate agendas, and ambition integrating policy, legislation, finance, sectoral activities and institutions, and coordinate capacity building, knowledge, and data spheres.
Comparing One Health and Planetary Health
The definitions and action plans they propose evolve and change over time (Lerner and Berg, 2017 ; de Castaneda et al, 2023).
One Health tends to be exhaustive essentially on the public health aspects (human and animal health priority area) and has recently integrated broad range environmental aspects. The program is carried out by a quadripartite cooperation between the global international organizations WHO, WOAH (animal health), FAO, and UNEP. This is a political network operating in association with governmental, financial, economic partners, civil society organizations, joint program networks, education and training activities, with national targets and priorities across sectors. For example, the 200 research networks - concentrated so far in Europe - investigate emerging infections and novel pathogens, endemic infections and NTDs, antimicrobial resistance, and extreme weather, water, environmental degradation, food safety, and food and nutrition security.
Planetary Health has been initiated by the Lancet-Rockefeller Foundation commission and the Planetary Health Alliance is built on a strong academic network (400 universities, among which Harvard, Oxford Martin School, Western, London Scool of Hygiene and Tropical Medicine, Sydney, California, Sunway), US and Chinese Academies, but also world leaders and experts from business, government (60 countries), and civil society organizations. The program is focused on teaching and training activities, and targets several environmental and health challenges (e.g., food systems and water, global pollution, climate, human pathologies).
The comparison highlights the fact that the main dimension that is apparently lacking or at least is not directly addressed is the social health per se. This is where our approach comes in (Manifeste pour une santé commune).
1) The health of nature over the long term. Examples concern biosphere functions and cycles within the critical zone as matrix of ecosystem services and externalities, and food chains as energy and biomass balance systems ;
(2) Social health by guaranteeing equitable access to resources, the foundation of fundamental rights and social cohesion ;
(3) Human health as a state of complete physical, mental, and social well-being.
