While self-reported life satisfaction (LS) has become an important research and policy tool, much debate still surrounds the question of what causes LS to change in certain individuals, while not in others. Set-point theory argues that individuals have a relatively resilient LS or "set point" (i.e. there is a certain LS level that individuals return to even after major life events). Here, we describe the extent to which LS varies over time for 12,643 individuals living in Australia who participated in at least eight annual waves of the Household Income and Labour Dynamics in Australia (HILDA) Survey. We use the standard deviation (SD) of year-on-year LS by individuals (SD of LS) as a measure of instability and an inverse proxy for resilience. We then model SD of LS as the dependent variable against average LS scores over time by individual, Big Five personality scores by individual, the number of waves the individual participated in, and other control variables. We found that SD of LS was higher (lower resilience) in participants with a lower average LS and greater degrees of extraver-sion and agreeableness. Set-point theory thus applies more to individuals whose average LS is already high and whose personality traits facilitate higher resilience. We were able to explain about 35% of the stability in LS. These results are critical in designing policies aimed at improving people's lives.

We explore the implications of four scenarios for the value of ecosystem services provided by terrestrial ecosystems to the year 2050 for Latin America and the Caribbean, based on the Great Transition Initiative scenarios and previous studies at a global scale. We estimated the current ecosystem services value (ESV) of the 33 countries that make up this region to be $US15.3 trillion/year. By modelling the four future scenarios, we estimated that there is a potential for ESV to decrease to $8 trillion/year (for the "Fortress World" scenario) or an increase to $19 trillion/year (for the "Great Transition" scenario), a difference of a 47% decrease or a 25% increase. Our results indicate that adopting appropriate policies could greatly enhance human well-being and sustainability in the region and help to achieve the UN Sustainable Development Goals (SDGs).

To achieve the objectives of the Paris Climate Agreement, a significant reduction in carbon dioxide emissions is needed, as well as increased removals by carbon sinks. In this context, we argue that Climate-Smart Forestry is a necessary, but still missing component in national strategies for implementing actions under the Paris Agreement. Climate-Smart Forestry is needed to (a) increase the total forest area and avoid deforestation, (b) connect mitigation with adaption measures to enhance the resilience of global forest resources, and (c) use wood for products that store carbon and substitute emission-intensive fossil and non-renewable products and materials. Successful Climate-Smart Forestry has important policy implications on finding the right balance between short and long-term goals, as well as between the need for wood production, the protection of biodiversity and the provision of other important ecosystem services. CSF thus can provide important co-benefits that are increasingly being recognized as essential for sustainable well-being

The Mekong River is the largest freshwater fishery and the third most bio-diverse river system in the world. Two of 11 planned mainstream hydropower projects, Xayaburi and Don Sahong, are nearly completed and a third project proposal, Pak Beng, has been submitted by the Lao PDR government for consideration. This paper builds on previous studies and examines the tradeoffs (between water use, food security supply and energy production) for the proposed mainstream hydropower projects in the Lower Mekong Basin (LMB). The paper concludes that the forecast loss of capture fisheries, sediment/nutrients and social mitigation costs measured as Net Present Value (NPV at 10% discount rate) are greater than the benefits from electricity generation, improved irrigation and flood control. The paper also forecasts huge negative economic impacts for Cambodia and Vietnam in contrast to previous Mekong River Commission's (MRC) conclusions that all countries will benefit from hydropower development. The paper recommends reassessing the economic impacts of hydropower development using full environmental cost accounting. It also recommends that a new LMB energy strategy be developed taking into account less hydropower income than previously anticipated, updated forecasts for LMB power demand and anticipated technology developments for improved energy efficiency & renewable energy (especially solar which is now competitive with hydropower).

Ecological economics views our world as an interconnected complex system of humanity embedded in the rest of nature. It is thus fundamentally a nexus approach. It recognizes four basic types of capital assets necessary, in a balanced way, to produce sustainable well-being of humans and the rest of nature. These include (1) built or manufactured capital, (2) human capital (e.g. human labour and knowledge), (3) social capital (e.g. communities, cultures and institutions, including the financial system) and natural capital (resources and natural ecosystems and their products that do not require human activity to build or maintain). Creating a sustainable and desirable future will require an integrated, systems-level redesign of our cities and our entire socioecological regime and economic paradigm focused explicitly and directly on the goal of sustainable quality of life and well-being with minimal waste rather than the proxy of unlimited material growth. It will require the recognition and measurement of the contributions of natural and social capital to sustainable well-being. It is a design problem on a massive scale. An integrated, nexus approach to urban and regional planning and design must be a central component of this process.

The United States and Canada have vast stores of ecological wealth that provide often unseen but critical benefits to the people and economy of each country. The close ties between ecology and the economy make it urgent that action is taken to address the risks of ecosystem degradation, but these close ties also present opportunities to develop new incentives for ecosystem conservation. To highlight the diversity of approaches being implemented in the US and Canada, we describe examples of programs seeking to maintain ecosystem services from ...
