Ce chapitre se concentre sur l'eau et les ressources énergétiques, considérées comme des ressources majeures indispensables aux sociétés humaines. Il examine les difficultés de gestion de ces ressources et les tensions socio-économiques et environnementales qui en résultent.
Question clé: Comment gérer durablement les ressources terrestres majeures ?
Le chapitre aborde deux aspects principaux :
Concernant l'eau, le chapitre présente sa répartition mondiale et introduit des concepts importants :
Vocabulaire:
- Eau fossile : eau enfermée dans les nappes phréatiques depuis des siècles, non renouvelable si puisée.
- Stress hydrique : situation où un territoire dispose de moins de 1700m³ d'eau par an et par habitant.
- Pénurie hydrique : situation encore plus critique avec moins de 1000m³ d'eau par an et par habitant.
Highlight: Seulement 0,6% de l'eau sur Terre est utilisable par les humains, ce qui souligne l'importance d'une gestion durable des ressources naturelles.

Ce chapitre approfondit la question de la répartition inégale des ressources, en particulier l'eau, et l'augmentation de la demande mondiale. Il présente une carte détaillée de la répartition de l'eau dans le monde, identifiant les zones en stress hydrique et en pénurie.
Exemple: Le centre de l'Australie, la Californie, le Sahara et le Golfe Persique sont cités comme exemples de régions confrontées à des problèmes d'eau.
Le chapitre aborde ensuite la question des ressources énergétiques, en distinguant les énergies fossiles non renouvelables (pétrole, gaz, charbon) et les énergies renouvelables (hydroélectricité, éolien, solaire, géothermie, biomasse).
Définition: Les ressources non renouvelables sont des ressources qui ne se renouvellent pas à l'échelle humaine, contrairement aux ressources renouvelables qui se régénèrent naturellement.
La demande croissante en ressources est analysée, avec une attention particulière sur l'utilisation de l'eau :
Highlight: Cette répartition inégale de l'utilisation de l'eau met en évidence la concurrence entre les différents utilisateurs, soulignant les enjeux de la gestion des ressources naturelles.

Ce chapitre examine l'explosion de la demande en ressources énergétiques depuis 1945 et les raisons de la prédominance des énergies non renouvelables dans l'économie mondiale.
Highlight: Les énergies non renouvelables restent privilégiées en raison de leur coût financier relativement bas et de leur facilité d'accès.
Le chapitre introduit le modèle économique capitaliste et libéral, expliquant son impact sur la consommation des ressources :
Définition: Le capitalisme est un système économique basé sur la propriété privée des moyens de production et la recherche du profit, favorisant la libre circulation des marchandises et de l'argent.
Exemple: L'Afrique, malgré une population qui a quadruplé en 50 ans, consomme le moins de ressources, contrairement à l'Europe dont la population n'a augmenté que de 20% sur la même période.
Cette disparité soulève des questions importantes sur les impacts sociétaux et environnementaux de notre modèle de consommation et met en lumière les défis actuels de la sociologie de l'environnement.
Question clé: Quels sont les impacts sociétaux et environnementaux de notre consommation inégale des ressources ?
Le chapitre conclut en soulignant l'importance d'une réflexion sur la gestion durable des ressources naturelles face aux défis posés par notre modèle économique actuel et les inégalités mondiales.

Ce chapitre examine les défis liés à l'exploitation et à la gestion des ressources naturelles vitales, en particulier l'eau et les ressources énergétiques. Il aborde la répartition inégale de ces ressources à l'échelle mondiale et l'augmentation de la demande, qui créent des tensions socio-économiques et environnementales.
Définition: Les ressources sont définies comme une richesse potentielle exploitée ou non par l'homme, pouvant être renouvelable ou non renouvelable.
Exemple: L'eau, le pétrole et le gaz sont des exemples de ressources majeures.
Le chapitre introduit le concept de développement durable comme cadre pour la gestion des ressources face aux rivalités entre utilisateurs et territoires. Il souligne l'importance d'une approche géopolitique des ressources.
Highlight: La gestion durable des ressources naturelles est cruciale pour faire face aux défis actuels et futurs liés à leur exploitation.
