Table 1 Key pathways and components in conceptual framework

From: Interlinking climate change with water-energy-food nexus and related ecosystem processes in California case studies

Components

Key pathways and factors

Notes

Major climate drivers’ factors

Temperature, snowpack, and precipitation for surface water, ground water, and stream flow. Fire for water quality in watershed; sea level rise for costal infrastructure

Focused on major drivers’ affects in water resources

Water life cycle

Water-pumping, conveyance, distribution and treatment, and urban and agricultural water use

Conveyance is a part of California water life cycle

Energy life cycle

Cooling, extraction, and processing for energy production, hydropower, biomass for biofuels, solar, wind, and geothermal energy production

Fossil energy has negative impacts on ecosystem processesa

Food life cycle

Irrigation (conveyance, treatment, pumping, pressurizing), harvesting and processing (cooling, washing, sorting, packaging, heating), fish and livestock production, transportation (growing and harvesting crops, shipping, distribution, import and export), food preparation (cooking), and waste (collecting and processing for food disposal)

Complex process related to water and energy

Affected key components in ecosystem process

Wetlands and watershed habitats, stream flow, water quality, biodiversity, cold water fish and wildlife species

Focused on affects from major drivers of water resources

  1. aFossil energy production and use increases greenhouse gas (GHG) emissions and alters ecosystem processes with decreased water quality and increased air pollution
