Abstract

Water, energy, and food are all essential components of human societies. Collectively, their respective resource systems are interconnected in what is called the “nexus”. There is growing consensus that a holistic understanding of the interdependencies and trade-offs between these sectors and other related systems is critical to solving many of the global challenges they present. While nexus research has grown exponentially since 2011, there is no unified, overarching approach, and the implementation of concepts remains hampered by the lack of clear case studies. Here, we present the results of a collaborative thought exercise involving 75 scientists and summarize them into 10 key recommendations covering: the most critical nexus issues of today, emerging themes, and where future efforts should be directed. We conclude that a nexus community of practice to promote open communication among researchers, to maintain and share standardized datasets, and to develop applied case studies will facilitate transparent comparisons of models and encourage the adoption of nexus approaches in practice.

Abstract

The energy-water-land nexus represents a critical leverage future policies must draw upon to reduce trade-offs between sustainable development objectives. Yet, existing long-term planning tools do not provide the scope or level of integration across the nexus to unravel important development constraints. Moreover, existing tools and data are not always made openly available or are implemented across disparate modeling platforms that can be difficult to link directly with modern scientific computing tools and databases. In this paper, we present the Nexus Solutions Tool (NEST): a new open modeling platform that integrates multi-scale energy-water-land resource optimization with distributed hydrological modeling. The new approach provides insights into the vulnerability of water, energy and land resources to future socioeconomic and climatic change and how multi-sectoral policies, technological solutions and investments can improve the resilience and sustainability of transformation pathways while avoiding counterproductive interactions among sectors. NEST can be applied at different spatial and temporal resolutions, and is designed specifically to tap into the growing body of open access geospatial data available through national inventories and the earth system modeling community. A case study analysis of the Indus River Basin in South Asia demonstrates the capability of the model to capture important interlinkages across system transformation pathways towards the United Nations' Sustainable Development Goals, including the intersections between local and regional transboundary policies and incremental investment costs from rapidly increasing regional consumption projected over the coming decades., Geoscientific Model Development Discussions, ISSN:1991-962X, ISSN:1991-9611

No. of bitstreams: 1 876216.pdf: 2646079 bytes, checksum: abc2a4059a9fc70302a9e8df63d82d5a (MD5) Previous issue date: 2017-02 Nos últimos anos a geração eólica tem crescido bastante no Brasil e no mundo. Porém, por ser uma fonte não despachável, variável, incerta, mas de baixo custo de geração, tem ocasionado impactos nos sistemas, adaptados a situações mais controláveis, e com menores incerteza. Esse trabalho busca compreender e analisar os impactos do aumento da penetração eólica no sistema elétrico do Brasil. Para isso, optou-se por simular a operação horária do subsistema elétrico do sul do país no modelo de despacho econômico Plexos. Foram simulados dois estudos de caso, um para 2030 e outro para 2050, onde foram comparados dois cenários, um de linha de base e outro de forte penetração eólica. A montagem desses cenários foi realizada com auxílio do modelo de expansão energética MESSAGE-Brasil. O MESSAGE-Brasil foi utilizado para a definir a capacidade de geração dos cenários dos estudos de caso. Dentre os principais resultados estão o aumento da importância da flexibilidade no sistema, maior dependência do intercâmbio de energia, redução das emissões e do custo de geração do sistema, além do indicativo de que usar as novas termoelétricas do sistema na base pode trazer vantagens de custo e abastecimento. Outro resultado a ser destacado é o déficit de energia ocorrido em todos os cenários, o que indica a não validação dos resultados do modelo de expansão no modelo de operação. Wind power developed in the last two decades and became a competitive energy source. The share of wind power had increased substantially in the Brazilian power system and in many systems around the world. However, wind generation is variable, uncertain, low-cost and non dispatched; hence these characteristics cause impacts in power systems. In this context, this dissertation aims to understand and analyze some of the wind power impacts in the Brazilian power system. For this, an hourly operation of the South Brazilian power system was simulated in the Plexos power model. First, this study modeled a validation case based on 2015 data. After that, two case studies were simulated, one for 2030 and another one for 2050. For each case, two scenarios were compared, a baseline and a wind policy scenario. To create these scenarios, the results of the MESSAGE-Brazil energy model was used as an input in Plexos. Results show that system flexibility becomes more important, increase in the dependence on energy exchange, emissions reductions and a decrease in generation costs. Besides, the utilization of thermal power plants as baseload generation can improve energy security and reduce the total cost of the system. Also, it is important to highlight that, in all scenarios simulated, there were generation deficits, which seems to indicate that the dispatch model used does not validate the results of the MESSAGE-Brazil expansion model.

Abstract

The world is going through intensive changes due to global warming. It is well known that the reduction in ice cover in the Arctic Ocean further contributes to increasing the atmospheric Arctic temperature due to the reduction of the albedo effect and increase in heat absorbed by the ocean’s surface. The Arctic ice cover also works like an insulation sheet, keeping the heat in the ocean from dissipating into the cold Arctic atmosphere. Increasing the salinity of the Arctic Ocean surface would allow the warmer and less salty North Atlantic Ocean current to flow on the surface of the Arctic Ocean considerably increasing the temperature of the Arctic atmosphere and release the ocean heat trapped under the ice. This paper argues that if the North Atlantic Ocean current could maintain the Arctic Ocean ice-free during the winter, the longwave radiation heat loss into space would be larger than the increase in heat absorption due to the albedo effect. This paper presents details of the fundamentals of the Arctic Ocean circulation and presents three possible approaches for increasing the salinity of the surface water of the Arctic Ocean. It then discusses that increasing the salinity of the Arctic Ocean would warm the atmosphere of the Arctic region, but cool down the oceans and possibly the Earth. However, it might take thousands of years for the effects of cooling the oceans to cool the global average atmospheric temperature.
