Environmentally Sustainable Aquaculture: An Eco-Physical Perspective

Longdill, Peter January 2008 (has links)
The New Zealand aquaculture industry during the late 1990s and early 2000s experienced a significant and sustained period of growth. Greenshell mussels (Perna canaliculus) are proving to be a popular and valuable cultured species, with large domestic and international markets. Traditionally, these bivalves have been farmed within enclosed embayments and on relatively small scales (~3 Ha). The recent expansion of the industry coupled with the near saturation of existing 'traditional' sites and new culture technologies has led the industry toward alternate environments, notably exposed offshore sites. Initial proposals within the Bay of Plenty have included multiple farms of ~4500 Ha each. This novel approach to shellfish culture created uncertainty with respect to potential environmental impacts, cumulative effects, and sustainable carrying capacities within these exposed open-coast locations. In zoning for Aquaculture Management Areas (AMAs), environmental managers must be informed of each of these aspects to ensure the rational and sustainable use of the coastal-marine space. The overall goal of this study is to determine the potential for environmentally sustainable large-scale offshore mussel culture within the Bay of Plenty marine environment. The long term sustainability of aquaculture development on an open coast is a function of many influences which can vary in both time and space. The benthic environments of the Bay of Plenty exhibit great variability in their ability to assimilate waste inputs from suspended mussel culture; a direct function of the variability in sedimentary environments and benthic habitats within the region. Specifically, silty sediments with low natural organic contents, generally found between 40 and 100 m depths are the most suitable locations for sustainable mussel aquaculture from an environmental impact perspective. Both observations and model predictions indicate productivity potential within the region to be greatest within neritic zones of the western Bay of Plenty. Local wind forcing is the predominant mechanism forcing local shelf currents. Current meter data and numerical modelling tests from this study indicate that local winds explain the majority of water current variability on the shelf, generate the delivery of new nutrients to the shelf through upwelling, and hence create the variability in productivity potential. Complicating the AMA zoning process for environmental managers, however, are existing uses of, and societal values toward, the coastal-marine environment. GIS planning tools have been shown to be effective at minimising conflicts and maximising sustainability potential through informed site selection. Within the Bay of Plenty, these preferential sites are located on the mid-shelf (60-80 m depths) offshore from Pukehina, Matata, and Whakatane. This study shows that the simulated cumulative lower trophic-level depletion impacts of two large (~5000 Ha) proposed offshore mussel farms vary seasonally as a result of subtle changes in ecosystem dynamics and mussel feeding patterns. At proposed stocking densities, largest relative impacts are expected during autumn and winter, when relative phytoplankton biomass is low and growth rates slow. During spring, while absolute impacts are greater than those during autumn/winter, greater phytoplankton-zooplankton biomass and faster growth rates result in quicker recovery times and reduced 'depletion halo' extents. Year-long predicted impacts are below those applied as 'acceptable limits of change', both within New Zealand and internationally, indicative of the ecological carrying capacity.

The Maintenance of Group Identity Through Social Networks in the Bay of Plenty Dutch Community

Webster, Kaye Louise January 2007 (has links)
Abel Tasman, a Dutchman, was the first person to put New Zealand on European maps over three hundred years ago (in 1642) and today there are over twenty-eight thousand people living in New Zealand who identify themselves as Dutch and twenty-seven thousand people speaking the Dutch language. Previous research has explored various aspects of Dutch migration, including migrant experiences, culture and language yet only de Bres (2004) compares the experiences of Dutch immigrants across time periods of their arrival. Cultural retention and maintenance has mainly been assessed via the use of the Dutch language rather than through other methods, such as Dutch customs and social networks. The main reason for this research is to compare the experiences and cultural identity of the three 'waves' of Dutch migrants, which has not been undertaken before. This study interviewed six Dutch settler families living in the Bay of Plenty, from three time-periods (1950s; 1960s to 1980s; and 1990s to today) and across generations in order to compare their experiences and assess if and how they maintain their Dutch identity through their use of customs and social networks. Open-ended questionnaires and interview schedules were used to interview the sixteen participants. Content analysis was undertaken for the majority of the questionnaire and interview schedules. For the remaining questions that focused on social networks, the structural aspects of the social support for participants were measured in terms of the social network characteristics, size, density and multiplexity. The study found an overall retention of Dutch identity across all time-periods for generation one (generation one refers to the migrating parents) with all families using the Dutch language within their own homes, yet only one family maintaining their Dutch identity through social networks and only one family maintaining their Dutch identity through the use of customs. The second and third generation participants have little to no interest or involvement in the Dutch culture or community. One second generation participant considered herself Dutch-Kiwi, with the remaining second generation participants considering themselves New Zealanders. Only one person from the third generation participated and she identified herself as a Dutch-Kiwi. Overall, this study supports the perception of the 'invisible Dutch' however due to the small sample size it is impossible to make conclusive statements concerning the Bay of Plenty Dutch community. There is a limited amount of research comparing the experiences of Dutch migrants and how their cultural identity is maintained through their social networks; therefore further research is required to fill this gap.

Farm-level vulnerability to climate change in the Eastern Bay of Plenty, New Zealand, in the context of multiple stressors

Cradock-Henry, Nicholas Andrew January 2011 (has links)
Climate change research is undergoing a monumental shift, from an almost exclusive focus on mitigation, and the reduction of greenhouse gases, to adaptation, and identifying the ways in which nations, communities and sectors might best respond to the reality of a changing climate. Vulnerability assessments are now being employed to identify the conditions to which socio ecological systems are exposed-sensitive and their capacity to adapt. Work has been conducted across a range of geographical locations and systems as diverse as healthcare and mining. There are however, few examples of analyses incorporating an assessment of the multiple climatic and non-climatic stressors to which agricultural producers are exposed. This thesis examines farm-level vulnerability to climate change of agricultural producers from the Eastern Bay of Plenty, New Zealand. The study area has a diverse agricultural economy, founded upon pastoral farming (dairy and drystock) and kiwifruit. This dependence on agricultural production, and the likely influence of expected changes in climatic conditions in the future provided a unique setting in which to develop a place-based case study exploring vulnerability to future climatic variability and change. Using a mixed methods approach, including semi-structured interviews and temporal analogues, a conceptual framework of farm-level vulnerability was developed and applied. The application of the framework was conducted through an empirical study that relied on engagement with and insights from producers who identified current exposure-sensitivity and adaptive capacity. It is shown that pastoral farmers and kiwifruit growers are exposed-sensitive to a range of climatic and non-climatic conditions that affect production, yields and farm income and returns. It demonstrates that producers have in turn, developed a range of short- and long-term adaptive strategies in order to better manage climatic conditions. It shows that these responses are varied, and are not made in response to climatic conditions alone, illustrating the need to consider other, multiple stimuli. An assessment of future vulnerability is presented, based on the empirical work and the identification of those drivers of vulnerability that are likely to be of concern and that will shape the capacity of farmers and growers to respond to climatic variability and change. The thesis as a whole not only provides a place-based case study on the vulnerability of farmers and kiwifruit growers in eastern New Zealand, but also demonstrates the need to engage with producers in order to develop an understanding of the complex ways in which climatic conditions interact with non-climatic stimuli beyond the farm-gate to influence vulnerability to climatic variability and change, both now and in the future.

The response to and recovery from the 2004 Eastern Bay of Plenty flood event : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Emergency Management at Massey University, Palmerston North, New Zealand

Busby, Eric January 2010 (has links)
Incident Management Systems used in New Zealand have their origins in the fire-fighting organisations of the United States of America in the 1970’s. They began in an atmosphere of disciplined quasi-military emergency response organizations. Emergency management research, theory and practice have since evolved to incorporate comprehensive facets acknowledging disasters are about people, individually and collectively and their environment. Emergency Management now includes addressing psycho-social aspects. New Zealand emergency services adopted the Coordinated Incident Management System (CIMS) as a result of a requirement following the Cave Creek disaster of 1995, where a multi- agency response to the event was found to be unsatisfactorily managed. Emergency management in the modern era now requires the orchestration of many and varied agencies and organisations including government and non-government organisations. These organisations are not necessarily suited to command type management styles and during a recovery phase of an incident, an approach involving a coordination style is more appropriate than a command style. An examination of the 2004 eastern Bay of Plenty flood event highlights that improved coordination by using a suitable incident management system benefits the response and recovery process. The Eastern Bay of Plenty community has social and cultural characteristics that impact on the effectiveness of emergency management outcomes. An incident management system that improves communication within the multi-agency organisation and between an emergency management organisation and the disaster-affected communities contributes to overall trauma reduction by stress reduction and facilitating early support and interventions. This allows where necessary, for modern emergency management to use systems that can utilise the unique community cultures, structures and networks that form the dynamic communities that they serve. If disasters magnify pre-existing social and community problems then the incident management system model used in a disaster can determine the degree of magnification.

The Ni-Vanuatu RSE-Worker : Earning, Spending, Saving, and Sending

Ericsson, Lina January 2009 (has links)
<p>In April 2007, New Zealand (NZ) launched the Recognised Seasonal Employer (RSE) scheme.  The scheme allows for unskilled workers from the Pacific Islands to enjoy the benefits of seasonal work in NZ’s horticulture and viticulture industries for up to seven months at a time.  One of the articulated objectives of the scheme is to advance the effects on development in the countries of origin of the workers, for which remittances have been stressed as key-benefits. Although previous data and interviews concerning these aspects are marginal, all studies indicate clear benefits for Pacific Islanders.  In contrast, this study provides the novel insight to the individual views and perceptions of the earning, saving, spending and remittance possibilities of 23 Ni-Vanuatu RSE workers in June of 2008.  The findings indicate an absence of autonomy among the individual RSE workers to decide over and manage the spending of their respective incomes, along with negative implications on the potential for workers to send remittances while working in NZ.  Identified as the primary cause of this outcome, is the dual and simultaneous role that NZ based companies, on the one hand, can play as recruitment agents in Vanuatu, and on the other hand, as pastoral care agents in NZ.  This twofold capacity creates a middle hand situation that severely restricts the possibilities for the workers to access their wages while in NZ.  The conclusion therefore holds that, in this example of 23 Ni-Vanuatu RSE workers, the degree of remittances depends on the type of employment governing the participation of the workers in the scheme, as opposed to the individual spending and saving patterns, differences in earnings, or differences in the availability of work of each worker respectively.</p> / <p>I april 2007 så startade Nya Zeeland (NZ) sitt Recognised Seasonal Employer (RSE) program.  Programmet tillåter lågutbildade arbetare från Söderhavsöarna att erhålla fördelaktigt säsongsarbete i NZ:s jordbruks industrier med upp till sju månader per arbetsperiod. Ett av de uttalade syftena med programmet är att avancera utvecklingen i arbetarnas hemländer, för vilket penningförsändelser från säsongsarbetet har lyfts fram som huvudsakliga förmåner. Trots att tidigare insamlad data och intervjuer som berör dessa delar av programmet är marginella, så har alla studier indikerat klara förmåner för säsongsarbetarna. Till skillnad från tidigare resultat, så påvisar denna studie nya insikter skildrade från ett perspektiv av 23 Ni-Vanuatu arbetare, och deras uppfattning om möjligheter till inkomst, sparande, och att kunna skicka penningförsändelser under en arbetsvistelse i juni 2008. Resultaten från studien pekar på en frånvaro av autonomi hos arbetarna att bestämma över hur deras inkomster skall spenderas, med negativa följder av att inte kunna skicka hem tillräckligt med pengar till sina anhöriga. Den identifierade primärorsaken till detta är framförallt den dubbelroll som NZ baserade företag, å ena sidan, kan spela som rekryterare av arbetskraft i Vanuatu, och å andra sidan, som förvaltare av arbetskraft i NZ. Denna dubbelroll skapar en mellanhandssituation som hindrar säsongsarbetarna från att tillgå sina inkomster under sin vistelse i NZ. Slutsatsen, i detta exempel av 23 Ni-Vanuatu arbetare, påvisar att nivån utav penningförsändelser beror på typ av anställningsform, istället för individuellt sparande eller spenderande av inkomster, skillnader i inkomst, eller skillnader i tillgängligt arbete för respektive arbetare.</p>
