No crop can be grown without being adequately supplied with the requisite amount of water at the proper time. A thorough knowledge of the hydrological cycle, amount and distribution of rainfall, water resources and irrigation projects in India facilitates efficient utilization of water for crop production. Inadequate supply of water to crops in semi-arid and arid regions adversely affects agricultural production. Properties of water, the mode of its entry into the soil and its absorption by roots of crops are important for irrigation. This necessitates accurate determination of the soil moisture content, the plants and available water which is essential for growth and yield of crops. Its deficiency adversely affects their growth and yield. Irrigation must be extended to unirrigated areas in order to increase the production of food, fibre and fodder for which we must know the source of irrigation water, units and methods of measurement of water, methods of irrigating crop fields, factors affecting the choice of irrigation methods, the degree of the suitability of the available water for irrigating crops and the factors affecting the suitability of water for irrigation. As water is a relatively scarce commodity, we must know whether water of a little inferior quality can be utilized to irrigate crops. In addition, we must be familiar with the precautions which need to be taken in this regard. The accumulation of excess water in the soils of the crop fields affects the growth of crops adversely enough to reduce their yields. Choice of the method of land drainage varies with the variation in the topography of the land. It is also necessary to rectify the causes of waterlogging to bring the waterlogged land back under the plough to increase agricultural production. This necessitates drainage investigation and laying out of the proper drainage system. Water requirement of crops depends on the climate and the crop. More water is required to produce crops in the arid region than in the humid region. Crops like paddy and sugar cane require much larger amount of water than finger millet and pearl millet. The book extensively deals with all these aspects related to soil and crop production and suggests measures to enhance productivity through water conservation and proper management of water resources. It will be highly useful for the students, teachers and researchers working in this field. Besides, agriculturists and general readers will also find it useful and informative.
“To avoid climate disaster, we have a single mission to protect, conserve and hand over the planet to the next generation. The time has already lapsed when we thought we could greedily exploit the exhaustible natural resources of mother earth. Now we have come to know that the world is not a piece of commodity to squander her natural wealth without offsetting the cost of emission or discharge of waste. There is only one considerably serious concern that will markedly define the future consequence of this planet more than any other, is the threat of global warming”….Inter Govt Panel On Climate Change Climate change is no longer a dilemma or a riddle to solve. Science has proved it beyond reasonable doubt. It is happening here and now with all of us where we have already crossed multiple tipping points of no return. Climate change is very complex, yet the solution is very simple. “Just stop burning fossil fuels”…A K Singh “We had a 67 percent chance of limiting the global temperature rise to below 1.50 C till 2018. We emit 42 Gt of CO2 every year. Now we have left not more than 420 Gt of CO2 budget to squander at current emission level within roughly another 8 years”….IPCC page 108, chapter 2. “People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of mass extinction. And all you can talk about is money and fairy tales of eternal economic growth. How dare you” !....Greta Thunberg Sweden
Throughout their lifecycle, from before birth until death, women are subjected to various forms of gender discrimination. In India, and the wider global context, there is widespread prevalence of discrimination, from dietary intake (both in quality and content), schooling, and clothing, to health and marriage. As this volume shows, overcoming each of these disparities leads to the empowerment of women. It focuses on disparities against women emanating under the framework of mortality, natality, basic facilities, special opportunities, professional work, and the household, highlighting possible ways of combating these prejudices.
Kashmir has always been in the midst of geopolitical hullabaloo due to its pending UN Resolution and now the demand of 'Azadi' (Freedom) which became more pronounced after the inception of insurgency in the State in 1987-88. If we look into the issue, in reality, it is a bilateral issue between India and Pakistan, if the legality reason is applied then there is no doubt that India's stance is most legitimate. The people of Kashmir have invited the 'Jihad' into Indian Kashmir Region and declared 'Azadi' as a war of freedom through the Pakistan sponsored militancy and radicalisation of the society on communal lines by the militant organisations and separatists. In the present environment, the stakeholders are at a tangent and it is mainly because the main stakeholder, the people of Kashmir are uncertain and confused, the total population is not part of the 'Azadi' (freedom) thus there is vagueness and the vision of 'Azadi' (freedom) is very blurred. The other stakeholders are either taking advantage of the people's sentiments or going by their own agenda of self-interest or lack the will to take initiatives to resolve the Kashmir issue which meets their personal ends. In this book, the chapters are based on the stakeholders and their participation in the Kashmir embroil. The basic contents are based on the issues that have made Kashmir an affair of continued existence by various stakeholders, the creation of an environment of stalemate and prevailing status quo without any changes, none of the stakeholders are ready to budge or lose their turf. Written in a simple and lucid manner, the narratives made interesting with historical facts, quotations and factual as prevailing in Kashmir.

The book ‘Kashmir Face-Off India’s Quandary’ is about Kashmir. How it remained in the suspended, animated state since 1947 in three parts Pakistan Occupied Kashmir, China Occupied Kashmir and rightfully held Indian Jammu and Kashmir. So many years have passed in status quo state and none of the actors is ready to budge an inch. The legal status of Jammu and Kashmir (J&K) as per the documentary evidence and seconded by the British Empire, the day the Maharaja of the State signed the Accord of Accession in 1947 October. This had made both Pakistan and China not recognising the accord. Pakistan invaded India to take by force J&K, Indian Army drove out the invading forces, but as ceasefire came into being certain territories were still held by Pakistan. Same was the case with China who in 1962 captured Aksai Chen and never returned it to India. These occupied territories were and have been used in fermenting problems and instability, based on communal lines with a view to breakaway Kashmir from India. With the abrogation of special status which Pakistan and China have been exploiting, both these countries got the jolt which they were never expecting. It was for the first time India declared the occupied territories as part of India in August 2019 and put the reclamation of the same. In this book, the modus, modalities and way out have been discussed to get back all the occupied territories, even at the cost of going in for forced reclamation. The narrative has been made interesting with Maps and debating the pros and cons, where India stands and what it must do to improving its posturing of reclamations.
In all, 1550 species of whiteflies have been identified. The rapid spread of Bemisia tabaci has occurred throughout the globe and it is regarded as the most notorious species. It is a complex species known to contain many biotypes namely, New World (Biotype -A), B-biotype MEAM1 (Biotype-B or Bemisia argentifolii, and MED (Biotype-Q) depending upon the geographical location. The complete information on the bio-ecology of important species along with the feeding mechanism has been presented in this book. The use of modern techniques of identification has added more biotypes considering the variations in host range, species of endosymbionts, virus transmission efficiency, and resistance to pesticides. The resistance and resurgence due to pesticides has been discussed in the monograph. The information on economic thresholds for judicious use of pesticides or release of natural enemies against whiteflies has been quoted in this compilation The pest control methods, namely chemical, cultural measures, biocontrol agents, resistant varieties, and mechanical devices have been elaborated on. Based on the availability of information the integrated model has been suggested to contain the whitefly menace under different situations. Considering the key factors responsible for the outbreak of whiteflies, a sound system of IPM has been formulated. The book also contains the use of semiochemicals and biotechnological tools likely to gain momentum in the future.
