Large reservoirs: are they the last Oasis for the survival of cities in India?
Full text linkUrban water demand is rapidly growing in India due to high growth in urban population and rapid industrialization. Meeting this growing demand is a big challenge for the urban planners in India. Incidentally, urban areas in arid and semi arid regions of India are experiencing rapid growth. As a result, the supplies from local water resources including aquifers are far less than the high and concentrated water demands in most urban areas. Under such situations, the cities have to rely on large reservoirs. The paper argues that urban growth would be jeopardized in absence of water supplies from large reservoirs. The analysis of 302 urban centres shows that as population of cities grow, their reliance on surface water sources also grows. Also, greater the share of surface water in the city water supplies, better the level of water supply. A multiple regression analysis of 190 class I cities and 240 class II towns further supports this finding. In Class I cities, with every unit increase in population, there is a 1.12 unit increase in quantum of water supplies. Whereas in Class II towns, with every increase in population, there is only a 0.40 unit increase in quantum of water supply. This shows greater capacities of large cities to respond to the growing water demands, induced by population growth and urbanization. The future projections of population growth, economic development and future water demands clearly means that the role of large reservoirs in meeting the demand of urban water supply is going to be more critical.urban water supply; large reservoirs; urbanization; population growth; India.

Co-Optimizing Solutions for Water and Food – Scoping the Nexus Challenges in the Agro-Sector and finding Scalable Business Solutions
Full text linkThe Water-Energy-Food (WEF) Nexus approach has an opportunity to create sustainable business solutions, especially in the agricultural sector. This report provides a clear understanding of challenges for the most promising and scalable solutions to the interconnected water, energy and food/feed/fiber problems, allowing combined co-optimization. Searching solutions for nexus challenges, a model based assessment of WEF nexus at global scale and a theoretical perspective of integrating economic and ecological objectives are presented. This study explores the opportunities for the global
community to develop robust partnerships and cross sector collaboration to foster water security and increase resource use efficiency, particularly in agriculture and food industry, as part of corporate environmental and financial performance goals

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
