title: The environmental and social impact of Kaivolution's services

authors: Paymani, Kesian Serous

subjects: food insecurity

abstract: Food insecurity and food waste are two significant issues within New Zealand. In order to address these two issues organisations like Kaivolution rescue and redistribute food to community groups who help those in need. Kaivolution rescues edible food from food retailers that would otherwise be thrown away, and redistributes this rescued food to community groups who assist whanau who are food insecure. The purpose of this thesis is to examine the social and environmental impact of Kaivolution’s food redistribution service. Three of Kaivolution’s stakeholders were chosen to participate; Kaivolution volunteers, community groups who receive the rescued food, and whanau who receive the food from the community groups. Semi-structured interviews were used in order to gather data. The key findings showed that for Kaivolution volunteers there was an increase in awareness of social issues like poverty, food insecurity, and homelessness. The findings also showed that the participants volunteering with Kaivolution had increased feelings of belonging, and increased social networks, both contributing to a heightened sense of wellbeing. The key findings from both the community groups and the whanau had significant overlap. Key findings from these participants illustrated how the process of colonisation has negatively impacted Māori who are more prone to food insecurity within Aotearoa. Other groups vulnerable to food insecurity included university students and children from various ethnicities. The findings also highlight the failings of our current social welfare system to provide enough resources for basic living. Community groups often step in to assist food insecure whanau in a culturally and social sensitive community approach to food redistribution. Such an approach promotes a sense of community, builds social relationships, and enhances whanau sense of self-worth and belonging.

title: Maori sustainable development in the 21st Century: The importance of Maori values, strategic planning and information systems

authors: Harmsworth, Garth

subjects: Development studies

abstract: The term ‘sustainable development’ has been widely used since the latter part of the 20th century. The concept implies economic and social development, economic growth, and environmental responsibility in order to sustain improved standards of living based on economic growth, to achieve some form of social equity, and to manage the environment in a sustainable way. Sustainable development should generally be at a rate that allows future generations to meet their needs without causing degradation of the natural environment, and should avoid economic or social decay. The concept has been debated and criticised by many as being ambiguous, untenable, and difficult to achieve, and frequently labelled part of global capitalism. But the concept provides a challenge to all of us, on how to balance economic, social, and cultural goals, while at the same time safeguarding and responsibly managing the environment for future generations. Attempts by indigenous peoples internationally to achieve sustainable development have been based on holistic approaches and frameworks that seek to balance economic, social, cultural and environmental objectives, and these provide effective models for viable sustainable development approaches. Māori Sustainable Development in Aotearoa-New Zealand is a term often used to describe a pathway to Māori autonomy, self-determination, the building of human and social capacity, as part of a strategic direction to capitalise on opportunities in the 21st century. This paper outlines research undertaken between 1998 and 2002 and funded by the Foundation for Research, Science, and Technology (FRST) in the programme “Māori Sustainable Development in Te Puku o Te Ika”, contract UOWX0005, simply referred to as the MSD programme. It focuses on the importance of determining Māori values, a vision, strategic planning and development of information systems as a holistic framework and process method to achieve Māori sustainable development.

title: Quantitative characterization of the multiscale mechanical properties of low-permeability sandstone roofs of coal seams based on nanoindentation and triaxial tests and its implications for CO2 geological sequestration

authors: Cao, F

abstract: Microstructural heterogeneity of low-permeability sandstone roofs of deep unmineable coal seams due to diagenesis significantly affects rock mechanical behavior, greatly impacting the sealing potential of in situ CO2 sequestration and the structural stability of the geological formation. However, little is known about how the microstructure of different mineral groups influences the multiscale mechanical behavior of deep sandstone. This study proposes a new method for quantitatively characterizing the multiscale mechanical properties of low-permeability sandstone and shows the mechanisms responsible for mechanical failure at the micro-, meso-, and macroscale. Triaxial compression tests and targeted nanoindentation tests were conducted to assess the micro- and macroscale mechanical properties of different types of sandstone. The micro- and macroscale experiments were coupled with numerical simulations of compression using a unified cohesive model based on Voronoi polygons to clarify the multiscale mechanical behavior. The results indicate that quartz, the primary mineral component of the sandstones examined, exhibits the strongest micromechanical properties, followed by feldspar, calcite, and clay minerals. Compared to polycrystalline quartz, monocrystalline quartz has a more stable microstructure and is mechanically stronger. The macro-mechanical properties of tight sandstone samples are weakened by increased microstructural inhomogeneity and larger grain size. This leads to a higher likelihood of splitting damage, characterized by a high degree of discrete and weak stress sensitivity. The major conclusion is that the positive rhythm lithofacies of medium-grained sandstone to siltstone are the most favorable for efficient CO2 sequestration in deep unmineable coal seams.
