title: Modelling of restoration scenarios for Lake Ngaroto

authors: Paul, Wendy J.

abstract: Waipa District Council is investigating restoration options for Lake Ngaroto, a shallow lake that has become hypertrophic through high external (catchment) nutrient loading from its catchment, which is associated with land use that is predominantly dairy farming. Shallow lakes like Lake Ngaroto, which have high external loading, typically have high internal nutrient loading, which may also need to be addressed to gain immediate improvements in water quality. By contrast, reduction of external nutrients is more likely to be associated with gradual and long-lasting effects on water quality.

This report is a culmination of data collection and analysis, and model development and simulation of restoration scenarios for Lake Ngaroto. Data were gathered on flow, nutrient concentrations,  temperature, dissolved oxygen, suspended sediments, meteorological variables and the lake morphology for the lake and its catchment. These data were used to produce a water balance and input files for DYRESM-CAEDYM, a one dimensional, coupled hydrodynamic-water quality model. Once calibrated, using the measured lake data (ammonium (NH4-N), nitrate (NO3-N), phosphate (PO4-P), total phosphorus (TP), total nitrogen (TN), chlorophyll a (Chl a), suspended solids (SS), temperature, dissolved oxygen (DO)) as a means of comparison for modelled data, a number of scenarios were carried out to simulate outcomes of lake restoration measures.

title: Indonesia-PNG Border Security

authors: Norotouw, Pascal

abstract: The field of international relations and security studies is among the most dynamic and challenging aspects of politics. Relationship between states depend on various factors such as politics, economic cooperation and socio-cultural partnerships. Despite the growing interdependency between states through the means of bilateral, multilateral or regionalism, security issues have remained to play a vital role in determining their level of cooperation and coexistence. This qualitative research entitled: Indonesia-PNG Border security, underlines Indonesia and PNG’s foreign policy while addressing the impacts of Papuan separatism on the 750km border. The relationship of Indonesia and PNG has remained cordial and robust over the years, however the existence of the Papuan conflict has often threatened to destabilize mutual understandings between the parties. 
The findings specify that the issue of Papuan separatism is one the sensitive and complicated political and cultural problems of the modern era. The sensitivity that lies behind the Papuan separatism issue has often caused difficulties to Indonesia and PNG policy makers. Border policies are designed to obtain the state objectives; however, cultural aspects have always benefited the third party (OPM) in their existence along the border. Subsequently, the Papuan autonomy has allowed for the acknowledgment of Papuan’s cultural rights. Moreover, the Papuan separatism has managed to gain support from many external parties. The growing participation of external parties have triggered internal security concern. This study indicates that the Papuan separatism issue will remain to influence Indonesia-PNG border security in the years to come. The designing of border policies should focus and encourage more on building trust as means of overcoming misunderstanding. More cooperation between all relative authorities such as the CIQS is vital to maintain a good and favorable a relationship.

title: Have you heard of Hinehau? A research journey of reclamation

authors: Wakefield, Sandy

subjects: Te Tai Tokerau

abstract: As the Māori political and cultural movement continues to grow, issues of representation, power, and control are critiqued by Māori minds.
After discovering a tribal myth about the mana of a woman known as Hinehau, a chain reaction of enquiry develops into the reclamation of tribal knowledge.
By investigating the historical context surrounding the narrative of Hinehau, her story transcends the fairy-tale myth she was confined to, and exposes the rendering down of her story.
Under the umbrella of Western science, European and Pākehā historical archives created an enduring legacy of “Māori myth” that is synonymous with falsehood. Through the assertation of tribal oral tradition and connecting our experiences to our missing histories, Hinehau is relocated. The Hinehau story renews through reconnecting to mātauranga Māori, Ngāpuhi kōrero tuku iho and the creativity of the researcher. In this process, her story renews.
With the guidance of hapū members, mentors, and a diversity of literature, the narrative of Hinehau becomes a part of a much larger inter-tribal narrative held within an ancestral landscape which is sometimes hard to recognise in whenua we no longer have tribal autonomy over. Our Indigenous identity is still under threat as we are still “othered” in our tribal lands. This work contributes to pushing the envelope of what it means to think, exist, and challenge as tangata whenua in Aotearoa, where traditional tribal roles have been minimalised in society, or disappeared through generations of the colonial project (Tuhiwai Smith, 2012).
