title: Relationship between science and technology in the New Zealand curriculum

authors: Jones, Alister

abstract: New Zealand underwent major curriculum reforms in the early1990s. These reforms were determined by the New Zealand Curriculum Framework (Ministry of Education 1993), which provides an overarching framework for the development of curricula in New Zealand and which defines seven broad essential learning areas. The seven essential learning areas that describe in broad terms the knowledge and understanding that all students need to acquire, are health and well-being, the arts, social sciences, technology, science, mathematics,and language and languages. For example, the essential learning area of science includes the subjects of science, biology, chemistry, physics, earth sciences, agriculture, horticulture, and geography, as well as aspects of home economics and environmental studies.

title: The Characteristics and Impacts of Landfill Leachate from Horotiu, New Zealand and Maseru, Lesotho: A Comparative Study

authors: Mohobane, Thabiso

subjects: leachate

abstract: Landfills are a potential pollution threat to both ground and surface water resources. This study focuses on two landfills, the Horotiu municipal waste landfill, near Hamilton, New Zealand, and the Maseru landfill in Lesotho. The Horotiu landfill is located less than 50 metres from the Waikato River and also sits on a shallow (lt;lm to water table) aquifer.  In Lesotho, the Maseru landfill is 4 km from a river and 2 km from a water reservoir and rests on a huge aquifer. Over 5000 people depend on groundwater in the area between the landfill and the river.  The objectives of my study were to: 1. compare and contrast conditions, management, and potential environmental impacts of the Horotiu and Maseru landfills; 2. evaluate the potential for groundwater contamination as the result of leachate migration; and 3. investigate the chemical characteristics of the landfill leachates and the impacts of the landfills on groundwater quality. 

The Horotiu study was based on the leachate and groundwater quality monitoring data obtained from the Hamilton City Council. Samples were collected every three months from 1991-2006 and analysed for about 30 chemical parameters. The data for the Maseru landfill consisted of groundwater quality collected by the author during July-September 2007 and borehole pumping data obtained from the Department of Water Affairs, in Lesotho. 

At Horotiu results indicate that the leachate had high concentrations of: NH4-N (630 mg/l), TOC (405 mg/l), BOD (126 mg/l), and COD (1289 mg/l), while heavy metals were in low concentrations (lt;0.1mg/l).   Leachate quality was found to change with time and with rainfall. Groundwater samples obtained from the landfill boreholes indicated that the Horotiu landfill had an influence in the quality of groundwater. Groundwater at the down-slope side of the landfill had higher concentrations of all chemical parameters, except for NO3-N, SO4-2 and Reactive P, than the groundwater on the upstream side. The mean groundwater quality at Horotiu was within New Zealand drinking water standards though some standards were exceeded by some individual samples.  

In the Maseru landfill, the borehole water had high concentrations of chemical parameters such as EC (1580 μS/cm) and Chloride (190 mg/l), compared to the national average of 250 μS/cm and 28 mg/l. The Maseru landfill groundwater quality was within the WHO drinking water standard for all analysed chemical constituents, except lead. 

Groundwater beneath both landfills was influenced by leachate but the impacts are currently not at an alarming stage, for analysed chemical parameters. At Maseru introduction of landfill linings has potential to reduce the effect of leachate on groundwater.

authors: Tauri, Juan Marcellus

subjects: Social justice

abstract: For this piece I take as my point of departure Biko Agozino’s response to a series of questions posed by a member of the audience, to a panel he was a member of during this time in New Zealand. The panel in question was part of the launch of a new journal, Decolonisation of Criminology and Justice, at AUT University, Auckland in June 2018. Biko was invited to give a speech at the launch of the journal, and participate in a panel discussion on the broad theme of ‘decolonising criminology and criminal justice’.
