title: Migration and mental health: Evidence from a natural experiment

authors: Stillman, Steven

subjects: migration

abstract: People migrate to improve their well-being. Yet a large literature suggests that migration can be a stressful process, with potentially negative impacts on mental health. However, to truly understand the effect of migration one must compare the mental health of migrants to what their mental health would be had they stayed in their home country. The existing literature is not able to do this. New Zealand allows a quota of Tongans to immigrate each year with a random ballot used to choose amongst the excess number of applicants. Experimental estimates of the mental health effects of migration are obtained by comparing the mental health of migrants who were successful applicants in the random ballot to the mental health of those who applied to migrate under the quota, but whose names were not drawn. Migration is found to lead to improvements in mental health, particularly for women and those with poor mental health.

title: Climate change increased extreme monsoon rainfall, flooding highly vulnerable communities in Pakistan

authors: Otto, Friederike E. L.

abstract: As a direct consequence of extreme monsoon rainfall throughout the summer 2022 season Pakistan experienced the worst flooding in its history. We employ a probabilistic event attribution methodology as well as a detailed assessment of the dynamics to understand the role of climate change in this event. Many of the available state-of-the-art climate models struggle to simulate these rainfall characteristics. Those that pass our evaluation test generally show a much smaller change in likelihood and intensity of extreme rainfall than the trend we found in the observations. This discrepancy suggests that long-term variability, or processes that our evaluation may not capture, can play an important role, rendering it infeasible to quantify the overall role of human-induced climate change. However, the majority of models and observations we have analysed show that intense rainfall has become heavier as Pakistan has warmed. Some of these models suggest climate change could have increased the rainfall intensity up to 50%. The devastating impacts were also driven by the proximity of human settlements, infrastructure (homes, buildings, bridges), and agricultural land to flood plains, inadequate infrastructure, limited ex-ante risk reduction capacity, an outdated river management system, underlying vulnerabilities driven by high poverty rates and socioeconomic factors (e.g. gender, age, income, and education), and ongoing political and economic instability. Both current conditions and the potential further increase in extreme peaks in rainfall over Pakistan in light of anthropogenic climate change, highlight the urgent need to reduce vulnerability to extreme weather in Pakistan.

title: Rangatahi of Ngāi Te Rangi Iwi: Cultural belonging and connectedness

authors: Benton, Chelsea

subjects: Māori

abstract: Rangatahi Māori (Māori youth) have one of the highest suicide rates in the OECD, they leave school earlier and with less qualifications, and suffer from higher rates of unemployment, hospitalisation and conduct and substance disorders and abuse than non-Māori. Sadly, many rangatahi move into adulthood only to experience poorer physical and mental health, shorter lifespans, and lower socioeconomic status compared to that of non-Māori. With these poor health outcomes for rangatahi Māori in mind this research explores the nature of Māori identities as a foundation for wellness, meaning, and flourishing. More importantly, this research takes into consideration the negative impacts of the colonisation of Māori and their cultural identity and the inter-generational effects of this long term systematic nature of disadvantage. I posit that cultural connectedness and belonging can foster healthy psychological and behavioural outcomes for rangatahi Māori. The mixed-method approach taken within this research sits within a Kaupapa Māori framework and draws upon accounts of 16 rangatahi Māori, aged between 10 and 14 years, who participated in a Ngāi Te Rangi Iwi based leadership development programme that reconnects rangatahi Māori with traditional customs and practices of their ancestors to enhance their health and wellbeing. Findings suggest that connectedness and belonging are manifest through practices such as Pēpeha, whakapapa, and Whakataukī/whakatauāki and rangatahi Māori draw on this cultural knowledge base and cultural practices to empower themselves, their whānau, hapū and Iwi. Rangatahi Māori in this sample also identified that whānau was most important in their lives followed by engagement in Māori culture. Findings highlight how Iwi organisations are stepping up to lead their people to a brighter future. For Māori, engaging with their Māoritanga and Te Ao Māori not only addresses the negative impacts of colonialism, but unlocks cultural potential, and an enhanced sense of self which serves to empower rangatahi Māori, their whānau, hapū and Iwi.
