5.3 Natural Resource Management and Conservation Practices

Natural resource management in Hawaiian culture balances human needs with ecosystem health. The ahupua'a system and mālama 'āina principle reflect deep-rooted values of environmental stewardship. Carrying capacity guides sustainable resource use, informing decisions on fishing, tourism, and urban planning.

Traditional Hawaiian practices like the kapu system and loko i'a fishponds demonstrate ancient conservation wisdom. Modern efforts build on these foundations, implementing marine protected areas, invasive species control, and endangered species recovery programs to preserve Hawaii's unique ecosystems.

• Natural resource management involves sustainable use and conservation of resources balancing human needs with ecosystem health
• Hawaiian culture emphasizes mālama 'āina (caring for the land) as fundamental principle
• Ahupua'a system divided land from mountain to sea enabling integrated resource management
• Kuleana (responsibility) to protect and nurture environment deeply ingrained in Hawaiian values

Explain the concept of carrying capacity and its application in resource management

• Carrying capacity represents maximum population size environment can sustain indefinitely
• Factors affecting carrying capacity include available resources (food, water, shelter), environmental conditions, and interspecies competition
• Resource managers apply carrying capacity to determine sustainable harvest levels (fish stocks)
• Concept used to set limits on tourism and recreational activities (beach capacity)
• Informs planning for population growth and urban development (infrastructure needs)

Conservation Practices in Hawaii

Describe traditional Hawaiian conservation practices

• Kapu system implemented seasonal restrictions on fishing and harvesting protected specific species during breeding seasons (ʻōpelu, akule)
• Loko i'a (fishponds) functioned as sustainable aquaculture systems integrating freshwater and marine ecosystems
• Agroforestry cultivated diverse crops in forest ecosystems preserving native plant species (koa, ʻōhiʻa)
• Water conservation techniques included ʻauwai (irrigation systems) and terraced agriculture for efficient water use (taro cultivation)

Discuss modern conservation efforts and their impact on Hawaiian ecosystems

• Marine protected areas establish no-take zones and implement coral reef restoration projects (Hanauma Bay)
• Invasive species management involves removal of non-native plants and animals utilizing biocontrol methods (mongoose control)
• Endangered species protection includes captive breeding programs and habitat restoration initiatives (nēnē goose recovery)
• Watershed management implements erosion control measures and reforestation of upland areas (Mauna Kea watershed)
• Sustainable tourism practices promote ecotourism initiatives and education programs for visitors (Haleakalā National Park)
