Without the constant use of natural resources, neither our economy nor our society could function. Nature provides humans with all resources necessary for life: energy for heat, electricity and mobility; wood for furniture and paper products; cotton for clothing; construction materials for our roads and houses; food and pure water for a healthy diet. However, the natural resource base our societies are built on is in severe danger of overexploitation and collapse.

  • 'Zero Carbon': the Wrong Problem Diagnosis, the Wrong 2050 Metric of Success, for New Zealand and the World
    ‘Zero Carbon’: The Wrong Problem Diagnosis, The Wrong 2050 Metric of Success, for New Zealand and The World. The government surely must agree?: Climate Change is 'merely' one symptom' of ‘The Real Problem’? ‘The Real Problem’ is that Humanity is living well beyond the bioregenerative capacity of the Planet's Ecosystem. (>70% Beyond!) 1970 was the last time the world was in balance, and ever since then the deficit has been steadily increasing without any sign of abating! (This with all the ‘amazing’ ‘Sustainability’ work going on around the world!) The ‘Issue’ is about ‘real’ 'Sustainable Living' and what ‘that’ really means for ‘The World’, a ‘Nation’, and right down to each, and every individual? I'm sure every New Zealander would agree: 'Sustainable Living', and being a 'Sustainable Nation', means: 'We' as a collective, should all be living within our 'fair share' of less than One Planet's, Ecological Regenerative Biocapacity limits? This surely must be, '‘The Ultimate Goal’' of humanity? It's well accepted that anthropogenic Carbon Emissions are a huge contributor to ‘The Real Problem’, but due to the inter-relationship between the Earth's bioregenerative resources, the solution, and particularly when looking to 2050, requires more than a simple, Carbon Emissions, or a ‘Zero Carbon’ focus. (This particularly for nation’s like NZ with strong and diverse Biocapacity Balance Sheets.) At an ‘enclosed system’, global level, a ‘Zero Carbon’ goal may have real relevance in solving ‘The Real Problem’, however, given the huge demographic, and biodiversity diversity between the nations of the world, setting ‘Zero Carbon’ goals at a nation level has the potential to delay, deceive, and confuse efforts to solve ‘The Real Problem’.

SUSTAINABILITY “State of the World 2013 assembles the wisdom and clarity of some of the earth’s finest thinkers, visionaries, and activists into a dazzling array of topics that merge to offer a compellingly lucid and accessible vision of where we are—and what is the wisest and healthiest course for the future.” OF THE WORLD STATE —NINA SIMONS, Cofounder, Bioneers Still Possible? “This edition forges a new path for the State of the World series, and for environmental thinking in general. A pivotal book that marks a defining moment for our species.” — RICHARD HEINBERG, Senior Fellow, Post Carbon Institute, and author of The End of Growth “State of the World 2013 is a powerful collection of articles, and the vision behind it is impressive. Here is a book that gets beyond ‘sustainababble’ and asks the tough, essential questions. It should make readers more determined than ever to do their part in avoiding planet-wide disaster—and better informed about how to do that.” — PETER SINGER, Professor of Bioethics, Princeton University, and author of Animal Liberation, One World, and The Life You Can Save Sustainability gets plenty of lip service, but the relentless worsening of key environmental trends reveals much of that attention to be “sustainababble.” From climate instability and species extinctions to approaching scarcities of freshwater, minerals, and energy, worrisome limits to human economic activity look more pressing each year—all while our political institutions seem impotent to address the challenge. THE WORLDWATCH INSTITUTE, in this edition of the celebrated State of the World series, takes an unflinching look at what the data say about the prospects for achieving true sustainability, 2013 what we should be doing now to make progress toward it, and how we might cope if we fail to do so.

  • The Ecological Footprint Emerged As a Response to the Challenge of Sustainable Development, Which Aims at Securing Everybody's Well-Being Within Planetary Constraints
    16 Ecological Footprint accounts The Ecological Footprint emerged as a response to the challenge of sustainable development, which aims at securing everybody's well-being within planetary constraints. It sharpens sustainable development efforts by offering a metric for this challenge’s core condition: keeping the human metabolism within the means of what the planet can renew. Therefore, Ecological Footprint accounting seeks to answer one particular question: How much of the biosphere’s (or any region’s) regenerative capacity does any human activity demand? The condition of keeping humanity’s material demands within the amount the planet can renew is a minimum requirement for sustainability. While human demands can exceed what the planet renew s for some time, exceeding it leads inevitably to (unsustainable) depletion of nature’s stocks. Such depletion can only be maintained temporarily. In this chapter we outline the underlying principles that are the foundation of Ecological Footprint accounting. 16 Ecological Footprint accounts Runninghead Right-hand pages: 16 Ecological Footprint accounts Runninghead Left-hand pages: Mathis Wackernagel et al. 16 Ecological Footprint accounts Principles 1 Mathis Wackernagel, Alessandro Galli, Laurel Hanscom, David Lin, Laetitia Mailhes, and Tony Drummond 1. Introduction – addressing all demands on nature, from carbon emissions to food and fibres Through the Paris Climate Agreement, nearly 200 countries agreed to keep global temperature rise to less than 2°C above the pre-industrial level. This goal implies ending fossil fuel use globally well before 2050 ( Anderson, 2015 ; Figueres et al., 2017 ; Rockström et al., 2017 ). The term “net carbon” in the agreement further suggests humanity needs far more than just a transition to clean energy; managing land to support many competing needs also will be crucial.

  • Effective Population Size and Genetic Conservation Criteria for Bull Trout
    North American Journal of Fisheries Management 21:756±764, 2001 q Copyright by the American Fisheries Society 2001 Effective Population Size and Genetic Conservation Criteria for Bull Trout B. E. RIEMAN* U.S. Department of Agriculture Forest Service, Rocky Mountain Research Station, 316 East Myrtle, Boise, Idaho 83702, USA F. W. A LLENDORF Division of Biological Sciences, University of Montana, Missoula, Montana 59812, USA Abstract.ÐEffective population size (Ne) is an important concept in the management of threatened species like bull trout Salvelinus con¯uentus. General guidelines suggest that effective population sizes of 50 or 500 are essential to minimize inbreeding effects or maintain adaptive genetic variation, respectively. Although Ne strongly depends on census population size, it also depends on demographic and life history characteristics that complicate any estimates. This is an especially dif®cult problem for species like bull trout, which have overlapping generations; biologists may monitor annual population number but lack more detailed information on demographic population structure or life history. We used a generalized, age-structured simulation model to relate Ne to adult numbers under a range of life histories and other conditions characteristic of bull trout populations. Effective population size varied strongly with the effects of the demographic and environmental variation included in our simulations. Our most realistic estimates of Ne were between about 0.5 and 1.0 times the mean number of adults spawning annually. We conclude that cautious long-term management goals for bull trout populations should include an average of at least 1,000 adults spawning each year. Where local populations are too small, managers should seek to conserve a collection of interconnected populations that is at least large enough in total to meet this minimum.

  • Geoengineering in the Anthropocene Through Regenerative Urbanism
    geosciences Review Geoengineering in the Anthropocene through Regenerative Urbanism Giles Thomson * and Peter Newman Curtin University Sustainability Policy Institute, Curtin University, Perth 6102, WA, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-8-9266-9030 Academic Editors: Carlos Alves and Jesus Martinez-Frias Received: 26 June 2016; Accepted: 13 October 2016; Published: 25 October 2016 Abstract: Human consumption patterns exceed planetary boundaries and stress on the biosphere can be expected to worsen. The recent “Paris Agreement” (COP21) represents a major international attempt to address risk associated with climate change through rapid decarbonisation. The mechanisms for implementation are yet to be determined and, while various large-scale geoengineering projects have been proposed, we argue a better solution may lie in cities. Large-scale green urbanism in cities and their bioregions would offer benefits commensurate to alternative geoengineering proposals, but this integrated approach carries less risk and has additional, multiple, social and economic benefits in addition to a reduction of urban ecological footprint. However, the key to success will require policy writers and city makers to deliver at scale and to high urban sustainability performance benchmarks. To better define urban sustainability performance, we describe three horizons of green urbanism: green design, that seeks to improve upon conventional development; sustainable development, that is the first step toward a net zero impact; and the emerging concept of regenerative urbanism, that enables biosphere repair. Examples of green urbanism exist that utilize technology and design to optimize urban metabolism and deliver net positive sustainability performance. If mainstreamed, regenerative approaches can make urban development a major urban geoengineering force, while simultaneously introducing life-affirming co-benefits to burgeoning cities.

  • Population Growth & Resource Capacity
    Population Growth & Resource Capacity Part 1 Population Projections Between 1950 and 2005, population growth in the U.S. has been nearly linear, as shown in figure 1. Figure 1 U.S. Population in Billions 0.4 0.3 0.2 Actual Growth 0.1 Linear Approximation - - - H L Year 1950 1960 1970 1980 1990 2000 2010 Source: Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. World Population Prospects: The 2010 Revision. If you looked at population growth over a longer period of time, you would see that it is not actually linear. However, over the relatively short period of time above, the growth looks nearly linear. A statistical technique called linear regression can create a linear function that approximates the actual population growth over this period very well. It turns out that this function is P = 0.0024444t + 0.15914 where t represents the time variable measured in years since 1950 and P represents the (approximate) population of the U.S. measured in billions of people. (If you take statistics, you’ll probably learn how to obtain this function.) The graph of this linear function is shown in the figure above. (1) Just to make sure that you understand how to work with this function, use it to complete the following table. The actual population values are given. If you are working with the function correctly, the values you obtain should be close to the actual population values!

Box 1346 Ann Arbor, Ml 48106-1346 rM£ S£S F 20 ABSTRACT Strategic Scarcity: The Origins and Impact of Environmental Conflict Ideas Elizabeth Hartmann This thesis examines the origins and impact of environmental conflict ideas. It focuses on the work of Canadian political scientist Thomas Homer-Dixon, whose model of environmental conflict achieved considerable prominence in U.S. foreign policy circles in the 1990s. The thesis argues that this success was due in part to widely shared neo-Malthusian assumptions about the Third World, and to the support of private foundations and policymakers with a strategic interest in promoting these views. It analyzes how population control became an important feature of American foreign policy and environmentalism in the post-World War Two period. It then describes the role of the "degradation narrative" — the belief that population pressures and poverty precipitate environmental degradation, migration, and violent conflict — in the development of the environment and security field.

  • Desertification and Agriculture
    BRIEFING Desertification and agriculture SUMMARY Desertification is a land degradation process that occurs in drylands. It affects the land's capacity to supply ecosystem services, such as producing food or hosting biodiversity, to mention the most well-known ones. Its drivers are related to both human activity and the climate, and depend on the specific context. More than 1 billion people in some 100 countries face some level of risk related to the effects of desertification. Climate change can further increase the risk of desertification for those regions of the world that may change into drylands for climatic reasons. Desertification is reversible, but that requires proper indicators to send out alerts about the potential risk of desertification while there is still time and scope for remedial action. However, issues related to the availability and comparability of data across various regions of the world pose big challenges when it comes to measuring and monitoring desertification processes. The United Nations Convention to Combat Desertification and the UN sustainable development goals provide a global framework for assessing desertification. The 2018 World Atlas of Desertification introduced the concept of 'convergence of evidence' to identify areas where multiple pressures cause land change processes relevant to land degradation, of which desertification is a striking example. Desertification involves many environmental and socio-economic aspects. It has many causes and triggers many consequences. A major cause is unsustainable agriculture, a major consequence is the threat to food production. To fully comprehend this two-way relationship requires to understand how agriculture affects land quality, what risks land degradation poses for agricultural production and to what extent a change in agricultural practices can reverse the trend.
