Land degradation caused by salinity and waterlogging is a global problem afflicting about one billion hectares and endangering the food security of at least 75 countries. Since the social, economic and environmental costs of on and/off-farm reclamation techniques are high, agroforestry is now emerging as a potential tool, not only for arresting salinity and waterlogging, but also for other environmental services like mitigating climate change, sequestering carbon and restoring biodiversity. This publication addresses the vital issues, principles and practices related to rehabilitation using agroforestry and includes many site-specific case studies from a number of the world’s typical catchments. Written by leading researchers, the book is a must, not only for scientists whose research interests lie in soil salinity, waterlogging and poor-quality waters, but also policy makers, environmentalists, students, and educationists alike. More importantly, it contributes to reversing the salinity trends and ensuring the livelihoods of resource-poor farming families living in these harsh agro-ecosystems.
Dietrich Kuchemann's The Aerodynamic Design of Aircraft is as relevant and as forward looking today as it was when it was first published in 1978. It comprises the philosophy and life's work of a unique and visionary intellect. Based upon material taught in a course at Imperial College London, the insight and intuition conveyed by this text are timeless. With its republication, Kuchemann's influence will extend to the next generation of aerospace industry students and practitioners and the vehicles they will produce. Kuchemann establishes three classes of aircraft based on the character of flow involved. Each class is suitable for a distinct cruise speed regime: classical and swept aircraft ...
The main purpose of this conference was for scientists/researchers from different parts of India to congregate to analyse and discuss their experiences on the management, genetic improvement, biochemistry, pests and diseases, ecology and utilisation of various Prosopis species.
Experimental investigation in turbulent boundary layer flows represents one of the canonical geometries of wall bounded shear flows. Utmost relevance of such experiments, however, is applied in the engineering applications in aerospace and marine industries. In particular, continuous effort is being imparted to explore the underlying physics of the flow in order to develop models for numerical tools and to achieve flow control. Flow control experiments have been widely investigated since 1930’s. Several flow control technique has been explored and have shown potential benefit. But the choice of control technique depends largely on the boundary condition and the type of application. Hence, ...

While technology is developing at a fast pace, urban planners and cities are still behind in finding effective ways to use technology to address citizen’s needs. Multiple aspects of sustainable urbanism are brought together in this book, along with advanced technologies and their connections to urban planning and management. It integrates urban studies, smart cities, AI, IoT, remote sensing, and GIS. Highlights include land use planning, spatial planning, and ecosystem-based information to improve economic opportunities. Urban planners and engineers will understand the use of AI in disaster management and the use of GIS in finding suitable landfill sites for sustainable waste management. F...
This report is based on interviews with the detainees' relatives, humanitarian workers, and human rights advocates, among others. The Sri Lankan government has routinely violated the fundamental rights of the detainees, Human Rights Watch found. The government contends that the 11,000 detainees are former fighters or supporters of the defeated Liberation Tigers of Tamil Eelam (LTTE).
It is the analysis of the physical and cultural aspects of the city. It examines the influences of the physical features and the historical events as well as the centripetal and centrifugal forces, in shaping the city morphology. The present life and functions and the Regional relations are analysed for suggesting remedies for the removal of the problems and the healthy urban development. Here the role of geographer in planning the healthy urban development is evident by pointing out the shortcomings of the official master plan.
