    Smart Management Consumption in Renewable Energy Fed Ecosystems

    Advances in embedded electronic systems, the development of new communication protocols, and the application of artificial intelligence paradigms have enabled the improvement of current automation systems of energy management. Embedded devices integrate different sensors with connectivity, computing resources, and reduced cost. Communication and cloud services increase their performance; however, there are limitations in the implementation of these technologies. If the cloud is used as the main source of services and resources, overload problems will occur. There are no models that facilitate the complete integration and interoperability in the facilities already created. This article proposes a model for the integration of smart energy management systems in new and already created facilities, using local embedded devices, Internet of Things communication protocols and services based on artificial intelligence paradigms. All services are distributed in the new smart grid network using edge and fog computing techniques. The model proposes an architecture both to be used as support for the development of smart services and for energy management control systems adapted to the installation: a group of buildings and/or houses that shares energy management and energy generation. Machine learning to predict consumption and energy generation, electric load classification, energy distribution control, and predictive maintenance are the main utilities integrated. As an experimental case, a facility that incorporates wind and solar generation is used for development and testing. Smart grid facilities, designed with artificial intelligence algorithms, implemented with Internet of Things protocols, and embedded control devices facilitate the development, cost reduction, and the integration of new services. In this work, a method to design, develop, and install smart services in self-consumption facilities is proposed. New smart services with reduced costs are installed and tested, confirming the advantages of the proposed model.This research was funded by the Industrial Computers and Computer Networks program (Informatica Industrial y redes de Computadores (I2RC)) (2018/2019) funded by the University of Alicante, Wak9 Holding BV company under the eo-TICCproject, and the Valencian Innovation Agency under scientific innovation unit (UCIE Ars Innovatio) of the University of Alicante at https://web.ua.es/es/ars-innovatio/unidad-cientifica-de-innovacion-ars-innovatio.html

    This report identifies and assesses climate-smart agricultural practices through participatory appraisal tools with experts and farmers, as part of the MICCA pilot project in Kaptumo, Kenya. The aim is to highlight and add climate-smart practices within the ongoing development programme which aims to integrate climate change adaptation and mitigation with improving livelihoods and productivity of the dairy farming system

    Importance of Sustainability on Agriculture in Southern Africa

    This paper seeks to describe and discuss the impact that climate changes, and other challenges in terms of sustainability, have had on Africa and particularly on South Africa. It seeks to discuss the extent to which these changes directly and indirectly impact agriculture and the measures that are currently underway, with particular reference to South Africa, as well as suggest other strategies that could be implemented to attenuate the effects of climate change, thereby advancing the global shift towards sustainability. The paper discusses environmental and other changes that have taken place in Africa and asserts that the continent is in a particularly difficult situation in light of the debate on sustainability versus productivity. The fact that most of the world’s rural poor depend on agriculture and that climatic changes have created new complications makes it more difficult to meet the MDGs and impedes economic development. This is especially relevant in light of the financial crisis and the drop in aid from the developed world. However, although more still needs to be done, it should be noted that significant progress has been made and projects and strategies are currently underway to utilize the region’s natural advantages.sustainability, agriculture, South Africa, climate change, Environmental Economics and Policy, Farm Management,

In order to supply their energy requirements, the consumers have changed the paradigm by integrating renewable energy sources to their power grid. Therefore, consumers become prosumers in which they internally generate and consume energy looking for an autonomous operation. This paper proposes an energy management system for coordinating the operation of distributed household prosumers. It was found that better performance is achieved when cooperative operation with other prosumers in a neighborhood environment is achieved. Simulation and experimental results validate the proposed strategy by comparing the performance of islanded prosumers with the operation in cooperative modePeer ReviewedPostprint (author's final draft

    More Circular City in the Energy and Ecological Transition: A Methodological Approach to Sustainable Urban Regeneration

    Get PDF
    Cities consume over 75% of natural resources, produce over 50% of global waste, and emit 60–80% of greenhouse gases. The scenario that by 2050 two thirds of the world population will live in cities, highlights how cities are still responsible for the growing consumption characterized by linear economic processes, with the production of various types of waste. In this unsustainable framework, the Circular Economy offers the opportunity to shape the urban system by means of rethinking the possibility to produce and use goods and services, exploring new ways to ensure long-term prosperity. The Circular City paradigm contains in fact all the principles of the Circular Economy: recovery, recycling, and sharing. In particular, Circular City also introduces actions related to the development of renewable energy communities, use of green materials, CO2 absorption approaches, and Proximity Cities. This work aims to develop a methodology to build a composite index (Circular City Index) capable of measuring the degree of implementation of urban policies that may enable an ecological transition of public assets. Circular City Index was applied to the military cluster of the city of Cagliari (Sardinia, Italy), a significant case study to guide circular policies in public properties for civil and military uses

    Scaling Up Climate Action to Achieve the Sustainable Development Goals

    Get PDF
    In 2015, UNDP released its first infographic report that presented the breadth and depth of our support on climate change over the past two decades. That report emphasized successes and noted the opportunities that climate action presents for countries as they transition their economies towards zero-carbon and climate-resilient sustainable development.This year, as countries begin to take concrete action to deliver on their national climate goals, we are pleased to release an updated report of UNDP's climate change work. New, in this report, is a special focus on the linkages between climate change and sustainable development. Specifically, the report highlights the importance of climate action in delivering on the SDGs and provides examples of UNDP's on-going work on the ground towards this end. The report also presents UNDP's commitment to scale up climate change action in order to deliver on the ambitious agenda that countries agreed to in 2015." – Magdy Martinez-Solima
