Abstract The stability and resilience of the Earth system human well-being are inseparably linked 1–3 , yet their interdependencies generally under-recognized; consequently, they often treated independently 4,5 . Here, we use modelling literature assessment to quantify safe just boundaries (ESBs) for climate, biosphere, water nutrient cycles, aerosols at global subglobal scales. We propose ESBs maintaining (safe ESBs) minimizing exposure significant harm humans from change (a necessary but...
Key insights on needs in urban regional governance - Global urbanization (the increasing concentration settlements of the world population), is a driver and accelerator shifts diversity, new cross-scale interactions, decoupling from ecological processes, risk exposure to shocks. Responding challenges demands fresh commitments city–regional perspective ways that are explictly embedded Anthopocene bio- techno- noospheres, extend existing understanding city–nature nexus scale. Three key...
The establishment of interdisciplinary Master's and PhD programs in sustainability science is opening up an exciting arena filled with opportunities for early-career scholars to address pressing challenges. However, embarking upon endeavor as scholar poses a unique set challenges: develop individual scientific identity strong specific methodological skill-set, while at the same time gaining ability understand communicate between different epistemologies. Here, we explore challenges that...
Abstract Non-technical summary We identify a set of essential recent advances in climate change research with high policy relevance, across natural and social sciences: (1) looming inevitability implications overshooting the 1.5°C warming limit, (2) urgent need for rapid managed fossil fuel phase-out, (3) challenges scaling carbon dioxide removal, (4) uncertainties regarding future contribution sinks, (5) intertwinedness crises biodiversity loss change, (6) compound events, (7) mountain...
Non-technical summary We summarize what we assess as the past year's most important findings within climate change research: limits to adaptation, vulnerability hotspots, new threats coming from climate–health nexus, (im)mobility and security, sustainable practices for land use finance, losses damages, inclusive societal decisions ways overcome structural barriers accelerate mitigation limit global warming below 2°C. Technical synthesize 10 topics research where there have been significant...
Climate change research is broad, diverse and constantly growing. Cross- interdisciplinary understanding essential for generating robust science advice policy. However, it challenging to prioritise navigate the ever-expanding peer-reviewed literature. To address this, we gathered input from experts across various fields through an online questionnaire prioritised a set of 10 key advances with high policy relevance. This year, focus on: (1) Declining aerosol emissions, (2) soaring methane (3)...
We explore how remittances shape the effect of rural out-migration on potential for local forest transitions. Building an existing theoretical model social-ecological regime shifts that links migration, farmland abandonment, and regrowth, we incorporate migrant as additional rural-urban teleconnection. also extend ecological dynamics to include a dynamical regrowth rate, generating slowing-down once landscape has undergone extensive agricultural change. first analyse these two extensions...
We propose a framework to support management that builds on social–ecological system perspective the Arctic Ocean. illustrate framework's application for two policy-relevant scenarios of climate-driven change, picturing shift in zooplankton composition and alternatively crab invasion. analyse archetypical dynamics between socio-economic, natural, governance systems these scenarios. Our holistic approach can help managers identify looming problems arising from complex interactions prioritise...
Energy microgrids have acquired great importance recently thanks to their main characteristics: decentralized generation, use of renewable energy sources in a distributed way, storage capacities and the possibility controlling managing power flows. This makes an excellent option reduce losses transmission distribution lines dependence on fossil fuels worldwide. article presents methodology for designing simulating operate countries located near equator. For this, several mathematical models...
In this study, the environmental behavior was characterized for a 840 Wp building-integrated photovoltaic (BIPV) system installed in Department of Physics Faculty Sciences at National University Colombia, Bogota campus. The methodology focused on application international technical standards Life Cycle Analysis (LCA) from cradle to grave based NTC ISO 14040 and 1404 standards, which regulate methodological procedure. This article is comparing potential impacts five power generation...
