Creating Flood Disasters: Environmental Memory and Adaptation in Aotearoa New Zealand
Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.This article explores three questions. First, why does New Zealand have widespread flooding hazards? Second, why are these persistent, with little seemingly learned from the memory of earlier events? And third, beyond reiterating conventional solutions, what examples of alternatives or adaptations are being developed in different places?

People and Nature, Volume 8, Issue 6, Page 1536-1555, June 2026.Abstract Tree‐planting initiatives are a crucial part of international sustainability and climate action efforts. Yet, many of these initiatives fail to achieve their long‐term sustainability and climate goals. The role of community value is an often‐overlooked factor in promoting the success of new tree plantings.

Journal of Physics: Conference Series, 2007 As the technological advances lead to miniaturization of mechanical devices, engineers face new challenges that are brought about by the fundamentally different rules that apply at small scales. One of the biggest problems in small machines is the excessive wear of the many surfaces that work in contact with each other, which severely constrains the ...

International Journal of Mental Health Nursing, Volume 35, Issue 3, June 2026.ABSTRACT Police and specialised police teams are frequently called to respond to mental health crises, often becoming de facto gatekeepers to care. Yet the perspectives of people in crisis and their carers remain underrepresented in the literature. The aim of this review is to explore the lived experiences of people, including carers, who encounter ...
