Air Pollution Monitoring System Using Micro Controller Atmega 32A and MQ135 Gas Sensor at Chandragiri Municipality of Kathmandu City

Air is one of the essential elements of human’s surroundings. The earth’s atmosphere is full of air which contains gases such as Nitrogen, Oxygen, Carbon Monoxide and traces of some rare elements. But quality of the air has been degrading for some decades due to various activities conducted by the human beings that directly or indirectly affect the atmosphere leading to the air pollution. There are different techniques to measure air quality.However, with the evolution of time the expensive and less efficient analog devices have been replaced by more efficient and less expensive electronics device. In this research, MQ135 sensor is used to measure air quality of a particular location. I2C display is used to monitor the data. Indeed, with the increasing in number of vehicles, unplanned urbanization and rapid population growth, air pollution has considerably increased in the last decades in various areas of Kathmandu. Thus, this project ‘Air Pollution Monitoring System’ was focused on collection of the data specific location of Chandragiri municipality of Kathmandu city. In conclusion,analysis of the data is done with the help of origin software which shows that the Arduino device in this device works perfectly for measuring the air pollution. Air quality of the selected area is found to be less than 500 PPM which concludes that the air quality of this area is normal

Forests of learning : experiences from research on an adaptive collaborative approach to community forestry in Nepal; a synthesis of lessons from the Adaptive Collaborative Management Research Project in Nepal, 1999–2002 and 2004–2007

In recent years, awareness has grown in Nepal and globally regarding two of community forestry’s most critical challenges: equity and livelihoods. Yet even as understanding of these challenges has improved, actors from the local to the national levels in Nepal continue to be confronted with the dilemma of how to address these challenges in such a diverse, complex and dynamic context. This synthesis explores an adaptive collaborative approach to governance and management as one avenue to meet these challenges. This approach integrates inclusive decision making, networking, social learning, and pro active adjustments of practice and policies based on learning. The synthesis’ lessons are drawn from a six-year partnership-based research initiative in Nepal—spearheaded by the Center for International Forestry Research—which spanned the local, district and national levels. Key points of learning discussed in this book include factors, processes and arrangements that support—or limit—adaptive and collaborative capacities, such as active facilitation, ‘nested’ decision making, and learning-based monitoring. The book also explores both the conceptual underpinnings of the approach as well as its effects in research sites, including in terms of benefits for the poor, women and other traditionally marginalised people. This book is intended as a resource for policy makers and civil society practitioners alike, as well as researchers and others interested in pro-equity and livelihood innovations in community forestry. Through its clear conceptual and research lesson focus, this synthesis complements and is a sister publication to the hands-on guidebook entitled Facilitating Forests of Learning

The challenging paradigm of interrelated energy systems towards a more sustainable future

This paper brings together several contemporary topics in energy systems aiming to provide a literature review based reflection on how several interrelated energy systems can contribute together to a more sustainable world. Some directions are discussed, such as the improvement of the energy efficiency and environmental performance of systems, the development of new technologies, the increase of the use of renewable energy sources, the promotion of holistic and multidisciplinary studies, and the implementation of new management rules and "eco-friendly and sustainable" oriented policies at different scales. The interrelations of the diverse energy systems are also discussed in order to address their main social, economic and environmental impacts. The subjects covered include the assessment of the electricity market and its main players (demand, supply, distribution), the evaluation of urban systems (buildings, transportation, commuting), the analysis of the implementation of renewable energy cooperatives, the discussion of the diffusion of the electric vehicle and the importance of new bioenergy systems. This paper also presents relevant research carried out in the framework of the Energy for Sustainability (EfS) Initiative of the University of Coimbra, linking the reviewed areas to the multidisciplinary approach adopted by the EfS Initiative. To conclude, several research topics that should be addressed in the near future are proposed
