Template for mapping SDG linkages for sustainable systems engineering

This model incorporates several options in examining fisheries dynamics and fisheries employment. The two most important aspects are the choice between I)managing based on setting fixed quota versus setting fixed effort , and ii) using the 'scientific advice' for quota setting  versus allowing 'political influence' on quota setting (the assumption here is that you have good estimates of recruitment and stock assessments that form the basis of 'scientific advice' and then 'political influnce' that desires increased quota beyond the scientific advice).

This is a model depicting Durham region waste management. It shows 4 types of waste, what township they come from, and how much waste (in tonnes) comes from each of the 3 townships in the Durham Region with a Durham Region-owned waste management facility. The garbage leftover from each township after removing everything recyclable, compostable, and reusable, is sent to the Durham York Energy Center to create energy from the garbage.

HANDY Model of Societal Collapse from Ecological Economics Paper 

Market-led Sustainability is  a 'Fix-that-Fails' as is illustraited in this graph in a very simplified manner. Likely market-led initiatives would be investment in renewables, electric cars and the development of long-term battery storage as a back-up to renewable energy adn other initiatives. However, all of these make demands on the environmemt, requiring  resources, fossil fuels (solar cannot beused to built  solar) and will be accompanied by greenhouse gas emission. In the medium and long term  they will undermine the market-driven goal,  increasing  environmental and economic costs.  The whole enterprise will eventually fail.
