This research evaluated using the Task Force on Climate-related Financial Disclosures (TCFD) methodology to assess climate change risk in forestry businesses. The key benefit of the TCFD approach is that it exposes business strategy, governance and operations to risk analysis and management and focuses on understanding any financial risks. This research is the first step on what the TCFD suggests is a five-year process. This analysis can start to define the climate change risk analysis.

The effect of projected future temperature and pH on coastal phytoplankton and biogeochemistry was determined in four mesocosm experiments. Warmer temperature had greater impact than lower pH, increasing phytoplankton biomass, altering size and dominant group, and affecting particulate Carbon:Nitrogen and fatty acids. However, zooplankton were largely unaffected, and application of the phytoplankton responses in a model indicated generally positive impacts on green-lipped mussels.

This briefing provides an update on: the Overseer peer review; a report reviewing Overseer’s transparency; S-Map extension progress; and other work in the Decision Support Tools work programme.
It also includes a letter for you to send to the Parliamentary Commissioner for the Environment (PCE) in response to his concerns about the Overseer work programme.

This briefing provides a recommended response from the Government to the Parliamentary Commissioner for the Environment’s (PCE) report on Overseer and regulatory oversight, including a draft letter to publicly respond to the PCE (Appendix Two).

This literature review synthesizes the current state of knowledge of marine non-indigenous species treatments, to help address biosecurity risks evident in two focal areas of relevance to marine biosecurity management in New Zealand. These two areas are:
1. the proactive treatment of shellfish aquaculture stock to facilitate biosecure stock transfers; and,
2. the reactive treatment of non-indigenous marine species to enable eradication at the landscape-scale.
The review summarises ~280 published papers in the global literature, outlining a number of chemical, physical and biological treatment options that have been tested to varying degrees. Each identified treatment type was assessed for several attributes in the review, including application regimes, efficacy, safety, the ability to monitor during deployment, biosecurity risks, and the regulatory environment that may influence acceptance and use in New Zealand. A number of these treatments are believed to be effective at small scales. Scaling-up one, or a combination of these identified treatments is likely the most efficient development route. Co-development and collaboration with the aquaculture, marine construction and commercial diving industries is likely to be critical to developing safe, effective and efficient implementation-ready treatment protocols..

This Risk Profile considers Listeria monocytogenes in RTE salads. This is an update of a Risk Profile “Listeria monocytogenes in ready-to-eat salads” published in 2005 (Lake et al., 2005).

This study developed a method to assess risk to benthic habitats from fishing, using holothurians on the Chatham Rise as a case study. A spatial population distribution layer was developed. This layer and the bottom-contacting trawl footprint were then used in a Bayesian spatial population model to calculate the biomass trajectory and spatially and temporally explicit impact overlap statistics for the taxon. Species susceptibility was either assumed or estimated within the population model.

Information was compiled on Listeria prevalence in an expanded definition of ready-to-eat (RTE) salads to include pre-dressed and fruit RTE salads. New Zealand studies have reported low prevalence of L. monocytogenes in packaged fruit salads and Listeria spp. from bagged leafy salads. Sprouted seeds and RTE fruit salads, particularly those containing melon, may represent more significant risks, but these foods are yet to be identified as risk factors in notified cases of listeriosis in NZ.
