    The book is an attempt to address the important facts and figures relating to climate change impacts on water security: a. Climate change impacts on water resources; b. Climate change impacts on water related diseases; c. Climate change impacts on water dependent biodiversity and ecosystems; d. Climate change adaptation and mitigation measures for water security; and e. Climate change and greenhouse gas emissions from water sector. ¿ Climate change is an additional stress on water security in addition to other chemical and biological stressors. ¿ Rivers depending on the Himalayan glaciers (the Indus, Ganges, Brahmaputra) could face water shortages or reduced river run-off due to retreat of glaciers, and this would cause dramatic impact on drinking water supplies, biodiversity, hydropower generation, industry, agriculture, ecosystems on which about 2.4 billion people in Asia depends. ¿ As a consequence of drought, the annual stream flow in the Murray-Darling basin (Australia) is projected to fall by 10-25% by 2050 and 16-48% by 2100 which would have severe consequences on irrigated agriculture in the region.

    The book comprises of topics on concepts of climate science and strategies to mitigate the impacts. The book therefore, covers topics of wider areas such as urbanization, coping strategies, water resources, watershed, land use patterns, atmospheric deposition, agriculture, carbon footprint etc. The book provides comprehension on which the researchers in the field may on which they can build up understanding on issues to be addressed. The articles are designed to interpret experiments, observations from the field and theory to understand the subject of climate change and its impacts.

    This book addresses the important issues of food security and sustainability of natural resources of India in the context of the projected climate change. Agroecosystems being the sites of intense interaction between human beings and natural world, global climate change is likely to affect the resource base, the crop productivity, input use efficiency and overall the profitability of agricultural production systems to a great extent. However, the adverse effects of climate change can be alleviated through mitigation and adaptation strategies which carry importance due to the increasing population and food demand in India. Thus, this compilation covers possible sources and sinks of greenhouse gases in Indian context including the potentials of soil carbon sequestration, crop pest and soil management and scientific livestock management as mitigation and adaptation options. This book also includes some topics on fundamentals of green house effect and the possible mechanisms by which soil nutrient availability alters due to CO2 fertilization. The schematic diagrams, tables and graphs have been included to make the book more illustrative. The likelihood of carbon credits and trading through best management practices can help Indian farmers earning carbon credits in future. The book is useful for researchers, farm managers, policy makers and also students engaged in climate change related studies.

    Weather and climate play an important role in plantation crops' production. While climate determines the adaptability of a particular crop in a region, weather determines the yield attributes of the crop. The global warming and climate change impacts on plantation crops are evident in the form of extreme weather events like floods, droughts, cold and heat waves and strong cyclonic winds, the frequency of which is likely to be more and more in the ensuing decades as noticed year after year around the globe in 1998, 2003, 2005, 2007, 2009, 2010, 2012, 2014 and 2015. It is now a topic of concern and the plantations' economy is in a threat in the ensuing decades due to climate variability. Decline in monsoon rainfall with number of rainy days, increasing ambient air temperatures (both day maximum and night minimum), decline in groundwater table, decline in wetland area and surface water resources, increasing number of forest fires and decline in forest area, increasing events of landslides during both the monsoon seasons, indiscriminate sand mining from river beds and unscientific land filling are the important climate change related issues in the Humid Tropics.

    The book has a comprehensive account of the climate change with possible projections on food security in India. Global scenario of extreme climatic events and the corresponding probable climatic parameters in the years to come are discussed elaborately. The effect of climatic variability on the productivity of crops particularly cereals, pulses, oilseeds, vegetables, fruits and flowers etc and incidences of plant diseases are highlighted. Moreover, the environmental effect on edible mushroom and rubber cultivation is also brought under the discussion in the book. Besides crop productivity, the information on the impact of climatic variability on the productivity/survival of livestock and freshwater fisheries is also made available. To avert weather vagaries, agro-advisory services on national perspectives are rendered with due importance. Finally, a focus on district level agro-advisory followed by a proper crop planning is also bestowed.

    The book is divided into four sections, minerals, crystals, rocks and ores. Section A incorporates nine s, begins with presenting salient features of the earth--its structure and composition. The second Minerals and Mineralogy briefly tells about their diversity and their categorisation and introduces the interesting way they are named. Crystal chemistry the third is the heart and soul of mineralogy and deals in somewhat details about the building blocks of minerals -atoms and ions and the way they form diverse types of minerals are. It tries to tell why every combination of chemical compounds cannot result into a naturally occurring mineral. The fourth and fifth s deal with Properties of Minerals, physical and optical. The s describe various physical properties that are helpful in the identification both in hand specimens and as thin section under the microscope. These two s are adequately aided with a number of illustrations, photographs and photomicrographs to bring home the point. five deals with classification of minerals and their occurrence and forms a prelude to the next two s on descriptive mineralogy. Important silicate and non silicate minerals are described in s eight and nine. A brief description of mineral uses is dealt with in both descriptive mineralogy as well Section D on mineral deposits, however, the last , Mineral uses presents an overall picture and will be interesting as well as educating to students and even general readeSection B is devoted to crystals and crystallography. one introduces the subject while two presents basic crystallographic elements. three deals with the main six crystals systems while also giving a preliminary idea about stereographic projection and x-ray crystallography. Section C covers petrology, beginning with introduction to science of petrology, rock nomenclature. two is devoted to the study of igneous rocks, including their forms, composition, textures, structures, classification and description. Sedimentary rocks is the theme of three while different aspects of metamorphic rocks including kinds and agents of metamorphism and classification and description of metamorphism. The last portion of this also considers metamorphism in the background of global tectonics. five, the rock cycle presents a concise summary of geological events that have shaped the planet earth. The last section D is what geology is all about for a man on the street and its significance in nation building--the Ore minerals. It begins with what ore is and its place in human affairs as a well as presenting the important terminology in economic geology. two deals with ore genesis and presents various hypogene and supergene process that carves out ore deposits from non economic materials. three, mineral deposits and global tectonics is becoming a very popular theme among the earth scientists. A brief introduction of the same will be certainly appreciated by the student community and prompt them for further study in this direction. A general survey of India's mineral resources is the theme of four. It covers almost all of the commonly used ores, metallic, non metallic or fuels. The last of section D and the boom, 'Indian mineral industry: some facts and figures' will present where our country stands in the realm of mineral resources. Latest available data of resources, production, export, import, organisations that matter and other useful facts and figures are presented.
