Aotearoa New Zealand’s waterways are valued for many reasons. However, nationally, their health has been declining. Animal agriculture is a significant contributor to this decline. The country’s largest farm, Molesworth Station, is managed to safeguard its cultural, conservation, recreation, historical and farming values. For this reason, managers of the station’s farming operation sought information on possible impacts of current animal agriculture on the habitat and water quality of Molesworth’s streams and rivers, and recommendations on monitoring and improving the health of its waterways over time. This thesis found the health of streams and rivers on Molesworth to be good. It provides recommendations on monitoring and management, including areas where action could be taken to address the likely impacts of fine deposited sediment on waterways. Given both the scale of Aotearoa New Zealand’s animal agriculture, and its impact on freshwater quality and habitat, improving the health of waterways will require an increase in pro-environmental behaviour from farmers and will need to be sustained. This thesis also looks beyond Molesworth Station to investigate the influence of basic human values on pro- environmental behaviour in Aotearoa New Zealand’s agricultural sector. It suggests that prioritisation and priming of certain basic human values are likely to suppress pro- environmental behaviour and posits that targeted values-sensitive communication could play a role in encouraging and increasing pro-environmental behaviour to meet the challenge of improving the health of waterways on agricultural land.
