Under the 2018 variations to the NSW RFAs, NSW renewed the commitment to supplying wood from public native forests in RFA regions at or below sustainable yield, and removed volume commitments. This approach is consistent with the NSW Government’s ongoing commitment to ecologically sustainable forest management and with wood supply volumes and arrangements in NSW. The original RFAs contained minimum wood supply volume commitments to industry. Although determined using the best available information at the time, the volumes became out-of-date and did not reflect refinements in modelled sustainable yields, reductions

PERMACULTURE AND SUSTAINABLE SITE DESIGN Today professionals and students in business, government, education, healthcare, building, economics, technology, and ntal environme sciences are being called upon to ‘design’ sustainable programs and activities. Through systems science we have learned that actions taken today can affect the viability of living systems to support human activity and evolution for many generations to come. Sustainability is a concept introduced to communicate the imperative for humanity to develop in nment our built enviro those conditions that will sustain the structures, functions, and processes inextricably linked with capacities for life. The challenge we face in this new era of sustainability is a realization that the goals and needs for developing sustainable conditions in our social environment are complex, diverse, and at times counter to the dynamics of ecological systems. In recent years ecology has been called upon to include the studies of how humans interrelate with ecological processes, within ecosystems. Although humans are part of the natural ecosystem when we speak of human ecology, the relationships between humanity and the t environment, i is helpful to think of the ‘environment’ as the social system. What are the relationships and interactions within this ecosystem? What are the relationships and interactions between the social system and ecological environment (this includes air, soil, water, physical living and nonliving structures)? How do the interactions systems, between affect the global ecosystem? The most fundamental means we have as a society in transforming human ecology is through modeling and designing in our social environment those conditions that will influence sustainable interactions and relationships within the global ecological system.

  • Maximum Sustainable Yield from Interacting Fish Stocks in an Uncertain World: Two Policy Choices and Underlying Trade-Offs Arxiv
    Maximum sustainable yield from interacting fish stocks in an uncertain world: two policy choices and underlying trade-offs Adrian Farcas Centre for Environment, Fisheries & Aquaculture Science Pakefield Road, Lowestoft NR33 0HT, United Kingdom [email protected] Axel G. Rossberg∗ Queen Mary University of London, School of Biological and Chemical Sciences, 327 Mile End Rd, London E1, United Kingdom and Centre for Environment, Fisheries & Aquaculture Science Pakefield Road, Lowestoft NR33 0HT, United Kingdom [email protected] 26 May 2016 c Crown copyright Abstract The case of fisheries management illustrates how the inherent structural instability of ecosystems can have deep-running policy implications. We contrast ten types of management plans to achieve maximum sustainable yields (MSY) from multiple stocks and compare their effectiveness based on a management strategy evalua- tion (MSE) that uses complex food webs in its operating model. Plans that target specific stock sizes (BMSY) consistently led to higher yields than plans targeting spe- cific fishing pressures (FMSY). A new self-optimising control rule, introduced here arXiv:1412.0199v6 [q-bio.PE] 31 May 2016 for its robustness to structural instability, led to intermediate yields. Most plans outperformed single-species management plans with pressure targets set without considering multispecies interactions. However, more refined plans to \maximise the yield from each stock separately", in the sense of a Nash equilibrium, produced total yields comparable to plans aiming to maximise total harvested biomass, and were more robust to structural instability. Our analyses highlight trade-offs between yields, amenability to negotiations, pressures on biodiversity, and continuity with current approaches in the European context.

  • Adding Value and Conserving Community Forests: the Case
    ADDING VALUE AND CONSERVING COMMUNITY FORESTS: THE CASE OF CERTIFICATION IN VERMONT, USA Mark Lorenzo Can independent third-party forest certification, as promoted by the internationally recognized Forest Stewardship Council (FSC) support the conservation of biological diversity in community forests while adding economic value to forest products? Vermont Family Forests (VFF), a fledgling community forestry initiative based in Bristol, Vermont (pop. 3800), earned the first FSC group certificate in the US, verifying that over thirty separate forest parcels were jointly well-managed. VFF is directed by the Addison County Forester, and works in partnership with the Vermont Sustainable Jobs Fund, and National Wildlife Federation to stem rates of forest loss and wildlife habitat decline by creating opportunities for improved economic returns commensurate with careful land stewardship. VFF marketing explicitly links ecological forestry practices on participating forests to creative, direct forest product marketing to customers and the general public. The family and community-owned forests in VFF operate in an ecological context of fragmented young second-growth forest, an economic context of increasingly global forest products markets, and a social context of controversy about forest practices and deforestation. VFF benefits from the counter-trend of interest in policies and programs that integrate community, economic and ecological sustainability, especially as to be implemented in "sustainable forest management". At this stage, FSC certification serves as an intervening filter between local forest ecosystems and economic markets, enhances community social capital, and helps generate market premiums. A Partnership for Sustainable Forest Conservation A nascent organization with volunteer leadership, VFF formed the Vermont Family Forestry Partnership (VFFP) to rapidly build capacity, conduct certified wood demonstration projects, and broaden community involvement.

We present a model for the development of economic and environmental). Maser (14) sustainable urban forests. The model applies general described sustainability as the "overlap between principles of sustainability to urban trees and forests. The central tenet of the model is that sustainable urban forests what is ecologically possible and what is societally require a healthy tree and forest resource, community-wide desired by the current generation", recognizing that support and a comprehensive management approach. For both will change over time. each of these components, we present criteria and indicators Therefore, our approach integrates the resource for assessing their status at a given point in time. The most significant outcome of a sustainable urban forest is to maintain (forests and their component trees) with the people a maximum level of net environmental, ecological, social, and who benefit from them. In so doing, we economic benefits over time. acknowledge the complexity of both the resource Creation and management of urban forests to itself and the management programs that influence achieve sustainability is the long-term goal of urban it. We also recognize that communities will vary in foresters. The notion of sustainability in urban both the ecological possibilities and societal forests is poorly defined in both scope and desires. application. Indeed, the question of how to define sustainability, and even whether it can be defined, Defining Sustainability is an open one (9, 12). At a simple level, "a In developing a model of sustainable urban sustainable system is one which survives or forests, we first examined how other sustainable persists" (5).

  • Identifying Ecosystem Key Factors to Support Sustainable Water Management
    sustainability Article Identifying Ecosystem Key Factors to Support Sustainable Water Management Rudy Vannevel * and Peter L.M. Goethals Department of Animal Sciences and Aquatic Ecology, Ghent University, Coupure Links 653, B-9000 Gent, Belgium; [email protected] * Correspondence: [email protected] Received: 31 December 2019; Accepted: 4 February 2020; Published: 5 February 2020 Abstract: There is a growing consensus that sustainable development requires a behavioral change, forced by firm decision-making. However, existing decision-supporting tools are unlikely to provide relevant information, hampered by the complexity of combined socio-economic and natural systems. Protecting the intrinsic value of ecosystems and providing sufficient natural resources for human use at the same time leads up to a wide span of management, ranging from species traits to governance. The aim of this study is to investigate the interactions between the natural and economic systems from the perspective of sustainable development. The way to reduce systems complexity by selecting key factors of ecosystem functioning for policy and management purposes is discussed. To achieve this, the Pentatope Model is used as a holistic framework, an ecosystem nodes network is developed to select key factors, and a combined natural and socio-economic valuation scheme is drawn. These key factors—abiotic resources and conditions, biodiversity, and biomass—are considered fundamental to the ecosystem properties habitat range and carrying capacity. Their characteristics are discussed in relation to sustainable water management. The conclusion is that sustainable development requires environmental decision-making that includes the intrinsic natural value, and should be supported by ecological modelling, additional environmental quality standards, and substance balances.

  • Marine Fisheries
    Marine Fisheries Summary Key policy messages Overall, it is considered that climate change could have a material impact on the feasibility of achieving the 25 Year Environment Plan (25YEP) fisheries goal of ‘ensuring that all marine fish stocks (in UK waters) are recovered to and maintained at levels that can produce their maximum sustainable yield (MSY), while protecting the wider marine environment’. Climate change has the potential to reduce the maximum sustainable yield, as well as impacting on the marine environment. The studies available suggest a decline in catch potential for England, for example, with up to 60% in a 4°C world by the end of the century. Climate change is therefore likely to make it harder to achieve the outcome, and could constrain the ambitions in the 25YEP. These impacts are likely to be much greater (disproportionately so) under a 4°C pathway. Climate change may also alter the suitability of different marine areas for different species, and thus affect Marine Protected Areas (especially when these have been designated for specific species). However, climate change does not feature heavily in the Fisheries White Paper, indeed, there is only one mention of climate change in the entire document, and there is no mention of climate change in the draft Fisheries Bill. Given the importance of these documents for driving future policy, this omission represents a major policy gap. This study has identified that there are additional adaptation options that can address these impacts, although further research is needed (especially on the implications of climate change on the achievability of the 25YEP target and the costs and benefits of adaptation to meet this).

  • Optimal Fishing Policies That Maximize Sustainable Ecosystem Services

Optimal Fishing Policies That Maximize Sustainable Ecosystem Services Hiroyuki Matsuda,1* Mitsutaku Makino2 and Koji Kotani3 1Faculty of Environment and Information Sciences Yokohama National University 79-7, Tokiwadai, Yokohama 240-8501, Japan 2National Research Institute of Fisheries Sciences Fisheries Research Agency 2-12-4, Fukuura, Yokohama 236-8648, Japan 3Graduate School of International Relations International University of Japan 777 Kokusai-cho, Niigata 949-7277, Japan *E-mail: [email protected] The classic theory of fisheries management seeks a maximum sustainable yield from a target species. There are several variations that include uncertainty, fluctuation, and species interactions. The knowledge that sustainable fisheries do not always guarantee conservation of a diversity of species is well known. Ecosystems provide several categories of ecosystem services to human well- being: supporting, provisioning, regulating, and cultural services. Fishery yields belong to provisioning services. The existence of living marine resources may maintain these services, and certainly a much larger contribution from regu- lating services than that from fishery yields. Therefore, we define an optimal fishing strategy that maximizes the total ecosystem service instead of a sus- tainable fishery yield. We call this the fishing policy for “maximum sustainable ecosystem service” (MSES). The regulating service likely depends on the stand- ing biomass, while the provisioning service from fisheries depends on the catch amount. We obtain fishing policies for MSES in a single species model with and without uncertainties and in multiple species models.
