POPCLIMA is structured into four research strands. A summary of the work performed is provided below.
Strand 1: Climate change effects on fertility
Two sub-projects have been carried out under Strand 1.
1) Impact of climatic factors on fertility in low- and middle-income countries
1.1 Climate change impacts on fertility in low- and middle-income countries: An analysis based on global subnational data (PI with Côme Cheritel & Roman Hoffmann)
1.2 Assessing the impact of temperature anomalies on fertility: A municipality-level analysis of birth rates in Mexico (1985-2020) (Itza Akari Olguín Zúñiga & PI with Côme Cheritel)
2) Climate change concern and fertility intention in European countries (Cross-sectional survey data)
2.1 Are climate change concerns related to fertility intentions and for whom? Evidence from five European countries (Irene Frageri, Francesca Zanasi & PI with Francesca Luppi and Alessandro Rosina)
2.2 Environmental uncertainty and fertility intentions: Reflections and first evidence from the Italian case (Chiara Puglisi & PI with Daniel Vignoli)
A manuscript has been submitted to the Special Issue “The Inequality of Uncertainty” of GENUS.
Strand 2: Climate change effects on mortality
Three sub-projects have been carried out under Strand 2.
1) Spatial and socio-economic heterogeneities in climate-related mortalities: A systematic literature review (Sirinya Kaikeaw, William Kemp, Rosanna Gualdi & PI)
2) Empirical analysis of exposure to temperature extremes on morbidity and mortality and heterogeneities in European countries
2.1 Extreme temperatures and morbidity in old age in Europe (Francesca Zanasi with Risto Conte Keivabu)

Strand 3: Climate change effects on migration
Three sub-projects have been carried out under Strand 3.
1) Climate change, aridity, and internal migration: Evidence from census microdata for 72 countries (PI with Roman Hoffmann, Guy Abel, Maurizio Malpede & Marco Percoco)
This previous version of the paper is published as a working paper.

The manuscript is accepted for publication in Nature Climate Change.
2) Unpacking the relationships between climatic shocks and conflict on migration intentions (Will Kemp, Jacopo Bassetto, & PI with Roman Hoffmann & Simone Ghislandi)
3) Migration estimates at high spatial resolution

Strand 4: Forecasting future population under future climate change
Strand 4 requires both conceptual and methodological development, as well as empirical inputs from the other three strands. Two works have been carried out to support Strand 4.
1) Methodological development
- High-resolution modelling and projecting local dynamics of differential vulnerability to urban heat stress (Led by Iulia Marginean with Jesus Crespo Cuaresma, Roman Hoffmann, PI, Jing Gao & Anne Sophie Daloz)
The manuscript is revised and resubmitted to Earth’s Future.
2) Conceptual development
2.1 Review of population projections used in the IPCC reports (Led by Sara Giarola with Leonardo Chiani, Laurent Drouet, Giacomo Marangoni, Francesco Nappo, PI & Massimo Tavoni)
Published in Giarola, S., Chiani, L., Drouet, L., Marangoni, G., Nappo, F., Muttarak, R., & Tavoni, M. (2024). Underestimating demographic uncertainties in the synthesis process of the IPCC. npj Climate Action, 3(1), 1–20.
