New paper in Nature on the implications of ending poverty on climate change, w/ a more realistic approach than existing lit. Good news: even with the most conservative assumptions, ending extreme poverty can be done without compromising climate goals.

Bold take from @TheEconomist in last issue: “Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s.”

#Adaptation finance is about more than dollar inflows, although this is vital. It’s about making sure that all investments protect people – esp the most vulnerable – from #climate impacts now and in the future. Blog by @hallegatte Jia Li &me. https://t.co/juR2rnrZR9 @WBG_Climate

Climate change adaptation requires more rapid development, more resilient development, and targeted adaptation. But climate finance numbers only capture the latter. How does the picture change with a broader perspective? New post w @FerzinaBanaji, Jia Li. https://t.co/2XoyIh6H4I

More work needed to represent prevention and preparedness measures, such as debt-financed adaptation investments or contingent credit lines. Many thanks to Florent McIsaac and Charl Jooste!

5 - The welfare impact of a disaster also depends on the ability of the economy to reallocate resources toward reconstruction, and the response of monetary policy (delaying monetary policy response makes the reconstruction faster and reduces total costs).

4 - The welfare impact of a disaster also depends on the preexisting economic situation: economies are (counterintuitively) more resilient during recessions

2- Welfare impacts — proxied by the discounted consumption loss — increase nonlinearly with direct asset losses. 3 - Macroeconomic responses reduce the welfare impact of minor disasters but magnify it when direct asset losses exceed the economy’s absorption capacity.

A few key findings: 1 - Destroyed infrastructure capital makes the remaining non-infrastructure capital less productive, which means that disasters reduce the total stock of capital and its marginal productivity.

The model is extended on 3 fronts: (1) distinction between infrastructure and non-infrastructure capital; (2) production function adjusted to account for short-term complementarity across assets; (3) reconstruction process is modeled to consider post-disaster constraints

A great pleasure to see our paper on the macroeconomic modeling of natural disasters published in Economic Modelling. The paper extends the @WorldBank Macrostructural Model to capture key transmission channels of disasters and their immediate aftermath. https://t.co/VxpYo4fYLX

After a very collaborative development of the Resilience Rating System methodologies, we piloted it on $2.9 billion in World Bank projects. It shows how considering risk and resilience helps design and implement better projects that deliver more and better development gains.

@hallegatte of the @WorldBank discusses the relationship between fostering #development and #resilience. They are not mutually exclusive, and should feed into the goal of reducing climate risk factors like poverty.

Really interesting work, and very aligned with some of our most recent work, counting people at high risk from climate change. Have a look!

Apparently pre-paying your car rental with @Avis does not mean you’ll have a car. If it’s important, better to go with the competition…
