title: Submission to Environment Committee on Inquiry on the Natural and Built Environments Bill

authors: Daya-Winterbottom, Trevor

abstract: Making submissions on the NBA exposure draft is difficult in the abstract, and the right to make further submissions on the full text of the Bill (and related legislation) when introduced into Parliament is reserved. For the reasons given below, the NBA exposure draft does not (as currently drafted) achieve the objectives set out in the terms of reference for the Parliamentary inquiry. Some suggested amendments to the NBA exposure draft are made in this submission. While the terms of reference for the Parliamentary inquiry do not include the counterfactual of amending the Resource Management Act 1991 (RMA) to achieve the stated objectives, an informed and critical appraisal of this approach was covered by Simon Upton in his RMLA Salmon Lecture 2020.1

title: Effects of local climate and hydrological conditions on the thermal regime of a reservoir at Tropic of Cancer, in southern China

authors: Wang, Sheng

subjects: thermal regime

abstract: Thermal regime is strongly associated with hydrodynamics in water, and it plays an important role in the dynamics of water quality and ecosystem succession of stratified reservoirs. Changes in both climate and hydrological conditions can modify thermal regimes. Liuxihe Reservoir (23°45′50″N; 113°46′52″E) is a large, stratified and deep reservoir in Guangdong Province, located at the Tropic of Cancer of southern China. The reservoir is a warm monomictic water body with a long period of summer stratification and a short period of mixing in winter. The vertical distribution of suspended particulate material and nutrients are influenced strongly by the thermal structure and the associated flow fields. The hypolimnion becomes anoxic in the stratified period, increasing the release of nutrients from the bottom sediments. Fifty-one years of climate and reservoir operational observations are used here to show the marked changes in local climate and reservoir operational schemes. The data show increasing air temperature and more violent oscillations in inflow volumes in the last decade, while the inter-annual water level fluctuations tend to be more moderate. To quantify the effects of changes in climate and hydrological conditions on thermal structure, we used a numerical simulation model to create scenarios incorporating different air temperatures, inflow volumes, and water levels. The simulations indicate that water column stability, the duration of the mixing period, and surface and outflow temperatures are influenced by both natural factors and by anthropogenic factors such as climate change and reservoir operation schemes. Under continuous warming and more stable storage in recent years, the simulations indicate greater water column stability and increased duration of stratification, while irregular large discharge events may reduce stability and lead to early mixing in autumn. Our results strongly suggest that more attention should be focused on water quality in years of extreme climate variation and hydrological conditions, and selective withdrawal of deep water may provide an efficient means to reduce internal loading in warm years.

title: Manaaki whenua. Manaaki tangata: Care for the land, care for the people: Leading critical school reform with mana whenua and whānau Māori

authors: Ford, Therese

subjects: Critical school reform

abstract: Education disparities between Māori and Pākehā students in Aotearoa, have their origins in colonial education policies and practices which considerably advantaged Pākehā students and compromised the ability of Māori students to engage with learning and succeed.  Despite the promises of equality inherent in the Treaty of Waitangi,  this historical foundation has, for over 150 years, perpetuated intergenerational cycles of education failure for Māori resulting in high levels of endemic social and economic disadvantage in many Māori communities.
This thesis examines the leadership praxis of two Pākehā principals, to understand how, with more respectful connections with Māori communities, they were able to address education disparities and facilitate success for Māori students as Māori. Culturally responsive research methodologies guided two, in-depth case studies which employed mixed methods.
Two collaborative stories, with the voices of mana whenua and whānau Māori, identified the importance of school leaders developing critical levels of consciousness, through authentic, bidirectional relationships with Māori communities.  These relationships enabled the principals to understand the authentic local, pre-colonial iwi histories of the land. This in turn fostered connections between the schools and local Māori communities that enabled them to collaboratively respond to the implications of colonisation.  
The thesis challenges the monocultural, monolingual, unidirectional policies and practices that characterise the current model of colonial education.  It presents instead a decolonising model of critical school reform and a framework for implementation and evaluation.  It contends that honouring the Treaty of Waitangi requires an equity focused response with power sharing relationships, critically led by principals alongside Māori communities.
