Needs And Pathways For Strengthening The Contribution Of Qualitative Methods Toward More Effective Impact Assessment Practice, Heidi Walker, A. John Sinclair, Alan P. Diduck, Alan Bond, Jenny Pope, Angus Morrison-Saunders, Francois Retief
Research outputs 2022 to 2026
Many jurisdictions are looking to next-generation impact assessment (IA) that includes sustainability considerations that extend beyond biophysical. Subjectivity is inherent in many of these additional impact considerations, and they are often not easily nor effectively quantified. Delivering effective IA within this broadening scope requires new, innovative, and rigorous applications of qualitative methods that enable meaningful inclusion of diverse knowledges, values, and information. While many qualitative methods are available for IA, there remains a significant opportunity to strengthen their contribution toward more effective IA practice. As such, we establish in this paper needs that must be addressed if qualitative methods are …

Young Women In Cities: Urbanization And Gender-Biased Migration, Yumi Koh, Jing Li, Yifan Wu, Junjian Yi, Hanzhe Zhang
Research Collection School Of Economics
Young women outnumber young men in cities in many countries during periods of economic growth and urbanization. This gender imbalance among young urbanites is more pronounced in larger cities. We use the gradual rollout of Special Economic Zones across China as a quasi-experiment to establish the causal impact of urbanization on gender-differentiated incentives to migrate. We highlight the role of the marriage market in increasing rural women’s chance of marrying and marrying up in urban areas during rapid urbanization.

In coastal urban areas, tidal flooding brings water carrying nutrients and particles back from land to estuarine and coastal waters. A statistical model to predict nutrient loads during tidal flooding events can help estimate nutrient loading from previous and future flooding events and adapt nutrient reduction strategies. We measured concentrations of dissolved inorganic nitrogen and phosphorus in floodwater at seven sentinel sites during 15 tidal flooding events from January 2019 to September 2020. The study area was the Lafayette River watershed in Norfolk, VA, USA, which is prone to tidal flooding and is predicted to experience more frequent and intense …

Widespread anthropogenic activities pollute groundwater that eventually seeps out to the coastal ocean. Here, we resolve nutrient transformations and fluxes in 11 sandy subterranean estuaries (STEs) with contrasting nutrient sources and development trajectories. Coastal groundwater nitrogen pollution stems from sewage discharge and land use change. Anthropogenically derived groundwater nutrient fluxes with high N/P ratios (∼170) accounted for 22%–61% of riverine inputs into China's coastal waters, providing an additional source of nutrients that can fuel coastal eutrophication and algal blooms. Sandy STEs remarkably attenuated ∼84% of nitrogen pollution, minimizing the impact of submarine groundwater discharge (SGD) on coastal water quality. Hence, …

Tropical cyclone (TC) impacts along the western Atlantic and Caribbean margin are not spatially uniform. Proxy based reconstructions of Common Era TC activity highlight this non-uniform distribution at centennial-millennial timescales. However, the sparse geographic scope of these reconstructions impedes our assessment of TC landfalls across broader spatial domains. This work presents a compilation of new and existing TC reconstructions from the Yucatan Peninsula for comparison with a contemporaneous compilation from New England, showing that these regions occupy distal nodes of a low-frequency TC dipole. Increased Yucatan (New England) storminess is closely linked to intervals of Northern Hemisphere warming (cooling) and …
