The SDGs give us a reading lens for finding the interlinkages of interest
The interlinkages are then studied with the underlying physical and social systems
GLOBAL GOALS IN PRACTICE
climate action can enable and reinforce building prosperous, equal and peaceful societies
CLIMATE ACTION AND THE SDGS 134 SYNERGIES ACROSS ALL SDGS
34 TRADE-OFFS ACROSS 12 SDGs

Climate action has many co-benefits on health (pollution),
energy and water systems, and efficient and circular
societies

But some important trade-offs exist
- Can be costly in the short term
- Can impact fuel-dependent economies

Assessing the Water-Energy-Food-Ecosystemsnexus in river basins
To identify benefits of transboundarycooperation & integratedwater resourcesmanagement (SDG 6.5)

Water-Energy-Food-Ecosystems nexus assessment
● Extensive coordination withstakeholders
● Quantitative modelling of interlinkages

Water-Energy-Food-Ecosystems nexus assessment
Agricultural activity
• What is the total irrigated area in the region?
Water demand
• What is the total water demand for irrigation?
• What is the impact of improving irrigation systems?
Electricity demand
• How much energy required for pumping? • If desalination would be needed, how much
energy would be required?
Electricity Supply
• What is the least cost electricity supply option?
Nexus in the North Western Sahara Aquifer
REFLECTIONS
● SDGs as a valuable starting point for decision-makers to select dynamics of interest and spur dialogue
● Then need to go to system level analyses to quantify and understand dynamics
● Especially important to understand the benefits to collaborate on nexus resources across borders (e.g. pursuing integrated water resources management - SDG 6.5)
