title: Reservoir Life Expectancy in Relation to Climate and Land-Use Changes: Case Study of the Mangla Reservoir in Pakistan

authors: Sarwar, Saleem

abstract: The dams and reservoirs are one of the largest sources to store surface water. The escalating water crisis in the new millennium has made it very important to preserve available water and in turn to preserve the storage capacity of dams and reservoirs. Dams and reservoirs lose their capacity due to sedimentation. Climate change and land-use changes have the potential to generate more sediment load hence accelerating this depleting process. An example is the Mangla Dam in Pakistan - the second largest dam in the country. Agriculture in the Punjab province, with almost 65% of the country’s population, is dependent on this dam. Due to sedimentation, the Mangla Reservoir has already lost 20% of its original storage capacity and an accelerated capacity loss is expected due to climate and land-use changes in the future.

In addition to mean climate factors, climate change will have a more profound impact on climate variability, which will likely lead to a more intensified and frequent extreme rainfall events than is currently experienced. Rainfall is the main driving factor of river sediment load, especially extreme rainfall events, which can cause exceptionally high sediment load compared to normal rainfall events. Therefore impacts of climate change was investigated by transient climate change scenarios from 1980 to 2098 constructed through bias correction of General Circulation Models (GCM) daily simulation outputs for the observed weather stations in the catchment. Land-use change scenarios were generated for two broad conditions based on socio-economic data and physical factors influencing the land-use: (i) pro-agriculture scenario and (ii) pro-industrialization scenario.

The impact of climate and land-use changes on the reservoir life was then investigated by using various combinations of climate change scenarios and land-use change scenarios. The results show that both climate and land-use changes can have significant impacts on the Mangla basin sediment transported by the river to the dam reservoir; climate change has a large impact on the annual sediment load, monthly variation in the sediment load, and in turn the reservoir life. The superimposed effects of land-use on climate change can exacerbate or reduce such impacts. Land-use change has the potential to effectively reduce climate change impacts. Therefore various land-use management measures were further evaluated based on economic analysis as adaptation options to mitigate the climate change impacts.

title: New Zealand Industry Training Policy in the 2008-2010 Environment

authors: Batters, Taryn

subjects: Industry Training

abstract: This study is broadly concerned with the changing nature of industry training policy in New Zealand between the mid-1980s and mid-2010. It sets the two-year period subsequent to the 2008 election against this broader background. Using key elements of the process of change within industry training policy – ideology and prevailing perceptions of skills and their contribution to economic and social goals – this research sought to investigate the extent to which the National-led Government’s policy approach and practices demonstrate ideological and policy change from the previous two decades. This study used a qualitative approach involving in-depth interviews with representatives of key organisations in industry training. These organisations include the Department of Labour, Ministry of Education, Tertiary Education Commission, Business NZ, Council of Trade Unions and the Industry Training Federation. Thematic analysis of interview data was combined with a review of existing literature in order to argue that the National-led Government’s claims of pragmatic orientation were not substantiated. Rather, it is argued here that the Government’s industry training policies aligned more closely with the neo-liberal policies of the 1990s, than with the Third Way of 1999-2008. For example, there was a deliberate retrenchment of government funding for industry training in some respects, and a significantly lessened role of the non-governmental key organisations in policy development. In addition, it is argued here that the National-led Government has demonstrated a narrow focus on skill development that contradicts wider advice and trends in favour of a multi-faceted view of skill that prioritises skill utilisation as well. Overall, it is argued that the National-led Government’s policy approach and practices are likely to be ineffective at addressing enduring issues in industry training as well as new issues.

title: He oranga tō te wai: Māori Pedagogies - A Culturally Responsive View of Aquatic Education and Drowning Prevention in Aotearoa

authors: Haimona, Mark Waihape

abstract: Drowning is a leading cause of accidental death and hospitalisation among Māori in Aotearoa. Drowning reports (Water Safety New Zealand, 2010, 2016, 2019) indicate Māori are over-represented in drowning compared to non-Māori, and on average account for up to a quarter of all drowning fatalities each year. Māori male aged 15-44 years and Māori children under five are most at risk of drowning (WSNZ, 2018, 2). A recent Aotearoa study on children’s water survival skills suggest changes are needed to improve how children develop fundamental aquatic skills and how teachers can best teach those skills (Button et al., 2017). In particular, the teaching of water safety skills for broader use in the open water environments of Aotearoa. 
Māori pedagogies within physical education, health, and education in the outdoors (Hemara, 2000; Jackson et al, 2016; Phillips, 2018) have demonstrated the benefits of Māori teaching methods that foster positive learning outcomes for Māori. (Bishop & Berryman, 2006, 2009). As such, this research investigated core components of Māori pedagogies that can improve aquatic education for Māori. It sought to validate traditional and contemporary aquatic teachings and water safety practices that Māori exercise as an expression of ira tangata (human development) and their relationship with te ao tūroa (the long-standing world). By means of kaupapa Māori research and the development of a new framework - Tāne Whānau Mārama, this thesis offers valuable insights into the importance of culturally responsive pedagogies in aquatic education that will enhance the health, educational achievements, and well-being of Māori whānau and communities.
