In January 1993 there were nuclea4 42 r power plant operation si n wit hcombinea d electricity generating capacit G(e)1 33 f .yo In 1992 these plants generated over 2027 TW.h electricity, equivalent to nearly 17% of the total. To achieve this, 57 200 tonnes uranium were required as nuclear fuel. Historically, nuclear fuel activities were primarily segregate mutuallo tw n di y exclusive areas consisting of WOCA (world outside centrally planned economy areas) and non-WOCA. Throughout most of the 1980s the WOCA uranium market experienced declining prices because of a very large excess uranium inventory resulting from over-productio earlien ni r years.

Emergenc thif eo s world market placed additional uraniu e stresth n so m supply and demand balance as the previously unavailable non-WOCA supply entered the market. This material came from both current productio existine th d ngan inventory. In recent years substantial uncertainties regarding uranium supply have mad vert ei y difficult for both uranium producer user d futuree san th pla o st r 199n I n.fo 2 uranium productio t onlnme y about 63 percent of reactor requirements. This resulted in a very unstable supply/demand balance where inventory drawdown (supplemented by minor amounts of reprocessing) filled the 20 960 tonne shortfall. The IAEA convened this Technical Committee meeting to take advantage of the new opportunities to collect and analyse information related to the future supply and demand balance and to help reduce uncertainties regarding the relationship. The meeting was effective in bringing together experts from all regions to share, exchange and disseminate information regarding uranium related activities. The Technical Committee Meeting on Recent Developments in Uranium Resources and Supply was held in Vienna from 24 to 26 May 1993. It was attended by 47 participants from 23 countries. Twenty-one papers were presented. Contributions from China Czece th , h Republic, India, Kazakhstan, Mongolia, Romani Russiae th d aan n Federation represen informatiow tne thin ni s field.

  • Nature-Based Infrastructure Solutions for Extreme Climate
    Living Root Bridge Ecosystems of Meghalaya, India: Nature-based Infrastructure Solutions for Extreme Climate By Sanjeev Shankar Published in PEDRR (Ecosystems for Disaster Risk Reduction and Adaptation) Newsletter 2020 Article adapted from original article published in Design with Life: Biotech Architecture and Resilient Cities by Maria Aiolova and Mitchell Joachim Figure 1. Double tier Living root bridge, Nongriat village, Meghalaya (2013) Current research and discourse surrounding integration of natural - living systems within infrastructure and buildings is often perceived as speculative, niche and avant garde. While this outlook has many underpinnings, the case study of ‘Ficus-based living root bridges of Meghalaya’ can provide rare real life practical evidence in support of this field, and inspire the global community to re-imagine the ‘built’ environment as a living-nourishing environment. Living Root Bridge Ecosystems are Ficus elastica1-based infrastructure and landscape solutions within dense sub tropical moist broadleaf forest ecoregions of North Eastern Indian Himalayas (25° 30’N and 91° 00’E). As living plant-based structural ecosystems, these infrastructure solutions are grown and nurtured by indigenous Khasi and Jaintia tribes of Meghalaya over decades and perform as critical rural connectivity and landscape solutions for several centuries in extreme climatic conditions2. With 1) low material and maintenance cost, 2) high robustness and longevity, 3) progressive increase in strength and performance, 4) community-led participatory design approach across multiple generations, 5) remedial impact on surrounding soil, water and air, 6) support for other plant and animal systems, 7) keystone role of Ficus plant species in local ecology, and 8) diverse morphologies including bridges, ladders, towers, viewing platforms and soil erosion/landslide prevention structures, Ficus-based living root structural ecosystems offer a compelling model for socio-ecological resilience and living plant-based sustainable infrastructure solutions.

  • A Handbook on the Gram Sevak Circle-Wise Village List of All the 39 Development Blocks of Meghalaya
    GOVERNMENT OF MEGHALAYA A HANDBOOK ON THE GRAM SEVAK CIRCLE-WISE VILLAGE LIST OF ALL THE 39 DEVELOPMENT BLOCKS OF MEGHALAYA (AS PER 2011 CENSUS) Directorate of Economics & Statistics Meghalaya, Shillong PREFACE The Handbook on the Gram Sevak circle-wise list of villages of Meghalaya - 2016 has been compiled based on the report submitted by the District Statistical Officers which are furnished by the Block Development Officers falling under their respective Districts. The hamlets/localities which are not notified as census villages as per census 2011 have been excluded from the Gram Sevak circles to bring into conformity with the village list of the population census 2011. During the population census 2011, the censuses on these hamlets/localities have been conducted as a hamlet/locality of the main/nearby notified census villages. I hope this Handbook will serve as a valuable source of information and ready reckoner to the Department concerned, economic planners, research scholars, students etc. about the villages falling within the Gram Sevak circles of each Development Block of all the Districts. Comments and suggestion from the users of this Handbook for improvement of its quality and usefulness will be highly appreciated. I would like to thank Shri Bruston Momin, R.O. who has compiled this Handbook. D. L. Wankhar, IES Director Page Index Name of the District Sl. No Name of the Dev.

The trip involved travelling through Meghalaya, Assam, Nagaland and Manipur, mainly by road with excursions on foot to explore the local flora. I work at a National Trust garden in Cornwall (Trelissick near Truro, on the Fal Estuary). Here we are fortunate enough to be able to grow many species of plants which originate in the Sino-Himalayan region, the flora of which extends right down into the parts of North East India which we visited on this expedition. My previous Head Gardener at Trelissick (Tom Clarke, currently Head Gardener at Exbury) has been on two previous expeditions to Arunachal Pradesh in NE India, to study the flora and in particular the rhododendrons found there. Tom’s experiences and photographs from these trips really fired my imagination, and we had discussed the possibility of me joining him on his next trip, since we share a strong interest in the flora of India and the Sino-Himalayan region. Tom Clarke had intended to join John Anderson on this study trip to North East India. In the event, Tom decided that he would not be able to make this trip due to other commitments, but he proposed that I take his place instead.
