Biochemistry is the study of the structure and functions of biological macromolecules such as nucleic acids, proteins, carbohydrates and lipids. The book is organized in five chapters which covers the basic concepts and fascinating chemistry of biomolecules. It also exposes students to different metabolic pathways and concept of energy in biological system, and provides valuable material for the students of Chemistry, Biochemistry, Biotechnology and Bioscience.

Agriculture is the backbone of our economic system. It provides not only food and raw material but also employment opportunities to a very large number of people. Higher atmospheric temperature has an impact on crop yields while the changes in rainfall could affect both crop quality and quantity. Climate change, therefore, could increase the prices of major crops in some regions. For the most vulnerable people, lower agricultural output means lower income. In addition, climate change is expected to increase the risk of illness and death from extreme heat and poor air quality. Recent evidence is the COVID-19 pandemic. Furthermore, climate change also affects the occurrence of other infectious diseases. A number of well-known diseases are climate-sensitive - malaria, dengue fever, and cholera among others. Tourism is considered as an industry and alternative contributor to a nation's income. It can generate employment opportunities and boost up the economy. This book, consisting of 26 chapters, focuses on the issues of agriculture, tourism and health for livelihood enhancement. It is essential to discuss these diverse issues in the field of geography as it encompasses interdisciplinary topics. The range of concerns at the national, regional and local levels is not confined to geography only but also involves other disciplines as well. Therefore, this book is a valuable source for scientists and researchers in allied fields such as livelihood, agriculture, land use, tourism management, health care and tribal studies. Furthermore, this book can be of immense help to the researchers, planners and decision makers engaged in solving problems in these areas in developing countries and beyond.

Geographic Information Systems (GIS) play a pivotal role in the field of urban planning and management and provide better solutions for numerous urban problems. With GIS, one has the ability to better understand existing requirements of a city and its design to fulfill those needs. This book contributes to developing scientific knowledge based on geospatial technologies among planners, researchers, scientists, professionals, students, and laymen and providing them with better understanding for urban planning and management at various levels. The book manifests the importance of GIS in better understanding of current urban challenges and provides new insights on how to apply GIS in urban planning. It also encourages the various stakeholders of society to participate in the decision-making process and assists planners and authorities to formulate suitable plans for sustainable urban growth of a region. The book is divided into two parts. The first part describes the fundamental concepts of GIS and also deals with the advanced techniques of spatial planning. The second part addresses real-world case studies using various applications of GIS. The case studies include urban land-use changes, simulation of future urban growth, urban heat island, alternate landfill site selection and urban flood susceptibility mapping, among others. This book shows how to integrate GIS with remote sensing, geostatistics, artificial intelligence-machine learning techniques, and other cutting-edge technologies. Readers find this book to be an invaluable resource for understanding and solving problems relating to sustainable urban planning and management.
