Need

The need for cumulative impact assessment (CIA) is increasingly being recognized. The development process for Australia's Harvest and Bycatch Policies, and their associated guidelines have reinforced the need for assessment of cumulative impacts, and the EPBC Act has also explicitly required consideration of cumulative impacts.

Where multiple activities occur or are planned, an understanding of their combined effects on the environment is necessary to address policy requirements and achieve sustainability. The concept of cumulative impact assessment is not new – indeed cumulative assessment has been recognized for many years, and a range of methods have been proposed around the globe. However, no methodology for undertaking cumulative assessments has been accepted nationally or globally. In addition to considering the impacts across all fishing sectors (commercial, recreational, indigenous, as required by recent changes to the Fisheries Administration Act 1991) and all fisheries, there is also an increasing need to consider other users of marine resources and coastal waters (e.g. renewable energy, shipping etc), especially where space crowding may be an issue.

Target species stock assessments typically consider the species of interest as well as other sources of fishing mortality (e.g. discards), but they do not usually consider their effects on other fisheries sectors or the effects of other sectors on the focal fishery. CIA methods therefore need to consider interactive and indirect effects. To date, interactive effects are often viewed as additive (simple linear addition of one impact to another) with little consideration given to synergistic, antagonistic or non-linear effects. While the ERAEF toolbox used for assessment of bycatch and protected species has some potential options for cumulative impacts (e.g. SAFE method), at this stage they are insufficient for moving to the scales and complexities across multiple fishing sectors and fisheries.

Thus, sustainable fisheries management requires new approaches that consider all sectors and all fisheries and how they impact the environment. Such CIAs will be challenging given that empirical data are often lacking - a dedicated research effort is needed.

Objectives

1. Undertake a two part review. This first part being to review existing cumulative impacts literature on methods applied elsewhere in the world, to produce design principles for a scalable cumulative impacts approach
and a synthesis of current benchmark methods and gaps in methods that must be filled to deliver Australian needs. And the second part being a global ERA review to identify cumulative impacts seen in other fisheries, with the specific focus of this review as specified by the AFMA led ERA/ERM working group – including looking: (i) at the assessment methods used elsewhere
(ii) their information needs and context
(iii) the strengths and weaknesses of the different approaches
(iv) synergies and efficiencies that can be adopted
and (v) recommend cost-effect ERA/ERM integration of additional methods that have been found to be appropriate given an AFMA context.
2. Characterise cumulative issues complicating cumulative impact assessments and, via a methods scan, deliver a list of options for addressing these issues
3. Develop a cumulative impacts framework that structures the sequence of analyses done for each assessment based on the characteristics of the sectors and ecological components involved– target, bycatch and protected species, and habitats and ecological communities
4. Perform an Australia-wide cumulative impacts assessment, with fishery-specific results, for (i) commonwealth fisheries across ecological components, (ii) indigenous and recreational sectors that interact with commonwealth fisheries for these components and (iii) and state and recreational fisheries where they overlap with Commonwealth fisheries.

Summary

The world is changing more rapidly than any one individual can track. The Environment Protection and Biodiversity Conservation Act 1999 (1999) (EPBC Act) requires for all human activities, such as fisheries, to be sustainable not only in isolation but in combination with other anthropogenic activities and the general state of the environment. It is difficult for fishery managers and operators to comply with this requirement without appropriate assessment methods. In addition, trying to understand the complete state of an ecosystem and all its interacting parts is a substantial and challenging task, especially for a nation with national waters as large and diverse as Australia’s.
In response researchers from the CSIRO and the University of Adelaide set about reviewing existing tools used to undertake Ecological Risk Assessments (ERAs) or Cumulative Effects Assessments (CEAs). This information then formed the basis for developing a new Cumulative Effects Assessment framework which was applied to 409 species around Australia to understand what the cumulative effects of fisheries are on Australia’s marine systems. This understanding and the recommendations made around strengthening existing assessment methods used by the Australian Fisheries Management Authority (AFMA) and other fisheries regulatory agencies will place Australia in a better place to ensure it is not only meeting regulatory requirements, but supporting sustainable industries and helping to coordinate across government agencies to safeguard healthy marine ecosystems into Australia’s future.

Need

The HIMI bioregion supports significant marine conservation values as well as a highly sustainable, and valuable commercial fishing industry. Typically, marine parks/reserve development processes are tasked with developing marine spatial planning arrangements that achieve a balance between preserving conservation values of the area and maintaining/promoting human activities through the principles of Ecologically Sustainable Development (ESD). However, key uncertainties remain regarding the policy priorities and how the final design of marine parks are objectively determined.

This project will provide an independent assessment of the framework used for original design of the HIMI Marine Reserve in 2002, the review in 2014, and the current review to provide recommendations for future development. The project will also explore how/if the policy objectives have been achieved since inception . Furthermore, this project will explore the potential of a quantitative risk-based approach to provide for minimising the uncertainties in the Marine Protected Area (MPA) development processes and deliver an objective framework.

In addition, the project will explore the current HIMI marine reserve framework, the associated commercial fishing industry arrangements and how they intersect with regard to:

Regulation
• Regulatory processes to minimise impacts of commercial fishing
• Legislative framework currently in place for Ecological Risk Assessment/ESD, Ecosystem-Based Fisheries Management, bycatch policy strategic research plans
• Marine Protected Areas review processes
• Statutory Fishing Rights (SFRs)

Economic impacts
• Commercial fishing viability
• Statutory fishing rights
• Permitted fishing gear types – (e.g. potential removal of MSC certified trawl fisheries with additional implications on research activity)

Biological impacts
• Impact on juvenile toothfish index of abundance and icefish estimates – accuracy of tracking stock will be significantly reduced if ability to trawl is removed (i.e. random stratified trawl survey impacted)
• Stock assessment model ability to consider toothfish population structure if longline fishery further constrained
• Climate change and effects of population shift
• Increasing policy position of MPAs as fisheries management tools
• Increased localised depletion and constrained ability to distribute commercial fishing effort

Social Impacts
• Market access
• Community sentiment

Objectives

1. Evaluate the technical approach used in the design of the HIMI marine reserve with specific reference to scientific and policy objectives
2. Examine management plan frameworks in regard to research outcomes since plan implementation
3. Provide recommendations in relation to review of the HIMI marine reserve

Summary

The statutory requirement to undertake a 10-year review of the Heard and McDonald Islands (HIMI) Marine Reserve led to a proposal to expand the HIMI marine reserve and include new National Park Zones (IUCN II) and Habitat Protection Zone (IUCN IV) arrangements. Subsequently, the total area of the HIMI Marine Reserve has been increased to 379,070 square kilometres, a 400% increase over the previous marine reserve. This report aims to assess how current (and proposed) management frameworks relate to the National Representative System of Marine Protected Areas (NRSMPA) objectives, but also the extent to which they meet the overarching principles of Ecologically Sustainable Development (ESD) which requires holistic consideration of all relevant environment, social and economic objectives, as well as meeting obligations under various international legislation and conventions. As the expansion incorporates the area within which Australia’s Heard Island and McDonald Islands Fishery operates, this report explores the basis of the expansion with particular reference to the implications for future fishery arrangements, management frameworks and longer-term fishery viability.
