Transcending capitalism growth strategies for biodiversity conservation.

The unlimited economic growth that fuels capitalism's metabolism has profoundly transformed a large portion of Earth. The resulting environmental destruction has led to an unprecedented rate of biodiversity loss. Following large-scale losses of habitats and species, it was recognized that biodiversity is crucial to maintaining functional ecosystems. We sought to continue the debate on the contradictions between economic growth and biodiversity in the conservation science literature and thus invite scholars to engage in reversing the biodiversity crisis through acknowledging the impacts of economic growth. In the 1970s, a global agenda was set to develop different milestones related to sustainable development, including green-blue economic growth, which despite not specifically addressing biodiversity reinforced the idea that economic development based on profit is compatible with the planet's ecology. Only after biodiversity loss captured the attention of environmental sciences researchers in the early 2000s was a global biodiversity agenda implemented. The agenda highlights biodiversity conservation as a major international challenge and recognizes that the main drivers of biodiversity loss derive from economic activities. The post-2000 biodiversity agendas, including the 2030 Agenda for Sustainable Development and the post-2020 Convention on Biological Diversity Global Strategy Framework, do not consider the negative impacts of growth-oriented strategies on biodiversity. As a result, global biodiversity conservation priorities are governed by the economic value of biodiversity and its assumed contribution to people's welfare. A large body of empirical evidence shows that unlimited economic growth is the main driver of biodiversity loss in the Anthropocene; thus, we strongly argue for sustainable degrowth and a fundamental shift in societal values. An equitable downscaling of the physical economy can improve ecological conditions, thus reducing biodiversity loss and consequently enhancing human well-being.

Trascendiendo las Estrategias de Crecimiento Capitalista para la Conservación de la Biodiversidad Resumen El crecimiento económico ilimitado que alimenta el metabolismo del capitalismo ha transformado profundamente una gran parte del planeta Tierra. La destrucción ambiental resultante ha traído como consecuencia una tasa sin precedentes de pérdida de diversidad biológica. Después de la pérdida a gran escala de hábitats y especies, se reconoció que la biodiversidad es crucial para mantener el funcionamiento de los ecosistemas. En este articulo buscamos seguir con el debate sobre las contradicciones entre el crecimiento económico y la biodiversidad en la literatura de las ciencias de la conservación y así invitar a los académicos a participar en la reducción de la crisis de biodiversidad dando a conocer los impactos del crecimiento económico. En la década de 1970, se estableció una agenda global para desarrollar diferentes metas relacionadas con el desarrollo sustentable, incluyendo el crecimiento económico verde y azul, la cual a pesar de no mencionar específicamente la biodiversidad reforzó la idea de que el desarrollo económico basado en ganancias es compatible con la ecología del planeta. Fue solamente después de que la pérdida de biodiversidad captó la atención de los investigadores de las ciencias ambientales a principios de la década de los 2000 que se implementó una agenda para la diversidad biológica. La agenda resalta que la conservación de la biodiversidad es un gran reto internacional y reconoce que las pincipales causas de la pérdida de la diversidad biológica derivan de las actividades económicas. Las agendas para la biodiversidad creadas después del 2000, incluyendo la Agenda 2030 para el Desarrollo Sustentable y el Marco de Trabajo de la Estrategia Mundial de la Convención sobre la Diversidad Biológica posterior a 2020, no consideran los impactos negativos de las estrategias para la biodiversidad orientadas por el crecimiento. Como resultado, las prioridades de la conservación mundial de la biodiversidad están gobernadas por el valor económico de la biodiversidad y la supuesta contribución que tiene para el bienestar de las personas. Una gran cantidad de evidencia empírica muestra que el crecimiento económico ilimitado es el principal conductor de la pérdida de diversidad biológica en el Antropoceno; por lo tanto, abogamos fuertemente por un decrecimiento sustentable y un cambio fundamental en los valores sociales. Una reducción equitativa de la economía física puede mejorar las condiciones ecológicas, reduciendo así la pérdida de biodiversidad y mejorando como consecuencia el bienestar humano.

Climate change and their impacts in the Balearic Islands: a guide for policy design in Mediterranean regions.

Understanding the local effects of global warming-derived impacts is important to island systems due to their fragile environmental conditions. This is especially true when it comes to Mediterranean insular regions as they are climate change (CC) hotspots where adaptation and mitigation policy design is an urgent matter. Looking at 2030 as a time horizon for climate action and focusing on the Balearic Islands, this paper reviews the physical changes projected for the coming decades as a result of CC and analyses their impacts on regional environmental, economic and social variables. Mitigation and adaptation measures are also proposed based on the identified priority impacts. The fact the Balearics are a top world holiday destination allows the analysis to serve as a guide to other Mediterranean islands with tourism-based economies facing similar CC scenarios. Results show the projected rise of temperature and sea level; the reduction of the average precipitation and increase in evapotranspiration, the droughts and the increase in ocean acidification and deoxygenation are the main threats faced by the Balearics, this putting their economy at risk due to the high tourism's vulnerability to CC. Mitigation and adaptation action on terrestrial and marine ecosystems, water resources, energy, infrastructure and urban planning, human health, economy, law and education is recommended. Sustainable mobility and waste managing are also viewed as important fields for mitigation action. Conclusions show that diversifying the current socioeconomic model is needed to increase the community and territory resilience.

Do we care about sustainability? An analysis of time sensitivity of social preferences under environmental time-persistent effects.

Environmental cost-benefit analysis has traditionally assumed that the value of benefits is sensitive to their timing and that outcomes are valued higher, the sooner in time they occur following implementation of a project or policy. Though, this assumption might have important implications especially for the social desirability of interventions aiming at counteracting time-persistent environmental problems, whose impacts occur in the long- and very long-term, respectively involving the present and future generations. This study analyzes the time sensitivity of social preferences for preservation policies of adaptation to climate change stresses. Results show that stated preferences are time insensitive, due to sustainability issues: individuals show insignificant differences in benefits they can experience within their own lifetimes compared to those which occur in the longer term, and which will instead be enjoyed by future generations. Whilst these results may be specific to the experimental design employed here, they do raise interesting questions regarding choices over time-persistent environmental problems, particularly in terms of the desirability of interventions which produce longer-term benefits.
