Key Terms to Review (23)
Agroecology: Agroecology is a holistic approach to farming that integrates ecological principles into agricultural practices, aiming for sustainability and resilience. It emphasizes the relationship between plants, animals, and the environment while promoting biodiversity and reducing reliance on synthetic inputs. By considering social, economic, and environmental factors, agroecology seeks to create agricultural systems that are more sustainable than conventional methods.
Aquaponics: Aquaponics is a sustainable farming method that combines aquaculture (raising fish) with hydroponics (growing plants in water without soil), creating a symbiotic environment where fish waste provides nutrients for the plants, and the plants help filter and purify the water for the fish. This system allows for efficient resource use, minimizing waste and maximizing productivity. It's essential for maintaining balanced ecosystems in both aquaculture and hydroponic settings, while also presenting unique challenges in design, implementation, and ongoing management.
Bill Mollison: Bill Mollison was an Australian ecologist and a pioneer of the permaculture movement, known for developing the concept of sustainable agriculture that works with nature rather than against it. His work emphasized holistic design principles that integrate land, resources, people, and the environment into productive ecosystems.
Biodiversity: Biodiversity refers to the variety of life in a given ecosystem, including the diversity of species, genetic variation within those species, and the complex interactions among them. This richness is crucial for ecosystem resilience and health, impacting everything from soil quality to pollination and pest control.
Care for the Earth: Care for the Earth is a fundamental principle of permaculture that emphasizes the importance of sustainable practices to maintain and enhance the health of our ecosystems.
