Though the impact of climate change will most likely be greatest with the already poor and vulnerable populations in the developing world, much of the writing about the costs and benefits of different policies to reduce greenhouse gas (GHG) emissions is by Western scholars, working in advanced industrialized economies. Drawing the majority of its contributions from authors based at Indian universities and other research centers, India and Global Climate Change provides a developing world perspective on the debate. With a population of over one billion, and an economy that is undergoing substantial restructuring and greatly increased economic growth after a number of years of stagnation, India has an exceptional stake in the debate about climate change policy. Using the Indian example, this volume looks at such policy issues as the energy economy relationships that drive GHG emissions; the options and costs for restricting GHG emissions while promoting sustainable development; and the design of innovative mechanisms for expanded international cooperation with GHG mitigation.

This open access book discusses the impact of human-induced global climate change on the regional climate and monsoons of the Indian subcontinent, adjoining Indian Ocean and the Himalayas. It documents the regional climate change projections based on the climate models used in the IPCC Fifth Assessment Report (AR5) and climate change modeling studies using the IITM Earth System Model (ESM) and CORDEX South Asia datasets. The IPCC assessment reports, published every 6–7 years, constitute important reference materials for major policy decisions on climate change, adaptation, and mitigation. While the IPCC assessment reports largely provide a global perspective on climate change, the focus on regional climate change aspects is considerably limited. The effects of climate change over the Indian subcontinent involve complex physical processes on different space and time scales, especially given that the mean climate of this region is generally shaped by the Indian monsoon and the unique high-elevation geographical features such as the Himalayas, the Western Ghats, the Tibetan Plateau and the adjoining Indian Ocean, Arabian Sea, and Bay of Bengal. This book also presents policy relevant information based on robust scientific analysis and assessments of the observed and projected future climate change over the Indian region.

This book brings together diverse perspectives concerning uncertainty and climate change in India. Uncertainty is a key factor shaping climate and environmental policy at international, national and local levels. Climate change and events such as cyclones, floods, droughts and changing rainfall patterns create uncertainties that planners, resource managers and local populations are regularly confronted with. In this context, uncertainty has emerged as a "wicked problem" for scientists and policymakers, resulting in highly debated and disputed decision-making. The book focuses on India, one of the most climatically vulnerable countries in the world, where there are stark socio-economic inequalities in addition to diverse geographic and climatic settings. Based on empirical research, it covers case studies from coastal Mumbai to dryland Kutch and the Sundarbans delta in West Bengal. These localities offer ecological contrasts, rural–urban diversity, varied exposure to different climate events, and diverse state and official responses. The book unpacks the diverse discourses, practices and politics of uncertainty and demonstrates profound differences through which the "above", "middle" and "below" understand and experience climate change and uncertainty. It also makes a case for bringing together diverse knowledges and approaches to understand and embrace climate-related uncertainties in order to facilitate transformative change. Appealing to a broad professional and student audience, the book draws on wide-ranging theoretical and conceptual approaches from climate science, historical analysis, science, technology and society studies, development studies and environmental studies. By looking at the intersection between local and diverse understandings of climate change and uncertainty with politics, culture, history and ecology, the book argues for plural and socially just ways to tackle climate change in India and beyond.

This report focuses on the risks of climate change to development in Sub-Saharan Africa, South East Asia and South Asia. Building on the 2012 report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, this new scientific analysis examines the likely impacts of present day, 2°C and 4°C warming on agricultural production, water resources, and coastal vulnerability. It finds many significant climate and development impacts are already being felt in some regions, and that as warming increases from present day (0.8°C) to 2°C and 4°C, multiple threats of increasing extreme heat waves, sea-level rise, more severe storms, droughts and floods are expected to have further severe negative implications for the poorest and most vulnerable. The report finds that agricultural yields will be affected across the three regions, with repercussions for food security, economic growth, and poverty reduction. In addition, urban areas have been identified as new clusters of vulnerability with urban dwellers, particularly the urban poor, facing significant vulnerability to climate change. In Sub-Saharan Africa, under 3°C global warming, savannas are projected to decrease from their current levels to approximately one-seventh of total land area and threaten pastoral livelihoods. Under 4°C warming, total hyper-arid and arid areas are projected to expand by 10 percent. In South East Asia, under 2°C warming, heat extremes that are virtually absent today would cover nearly 60-70 percent of total land area in northern-hemisphere summer, adversely impacting ecosystems. Under 4°C warming, rural populations would face mounting pressures from sea-level rise, increased tropical cyclone intensity, storm surges, saltwater intrusions, and loss of marine ecosystem services. In South Asia, the potential sudden onset of disturbances to the monsoon system and rising peak temperatures would put water and food resources at severe risk. Well before 2°C warming occurs, substantial reductions in the frequency of low snow years is projected to cause substantial reductions in dry season flow, threatening agriculture. Many of the worst climate impacts could still be avoided by holding warming below 2°C, but the window for action is closing rapidly. Urgent action is also needed to build resilience to a rapidly warming world that will pose significant risks to agriculture, water resources, coastal infrastructure, and human health.

Climate change will lead to many changes in global development and security especially energy, water, food, society, job, diplomacy, culture, economy and trade. The Intergovernmental Panel on Climate Change (IPCC) defines climate change as: “Any change in climate over time, whether due to natural variability or as a result of human activity.” Global climate change has emerged as a key issue in both political and economic arenas. It is an increasingly questioned phenomenon, and progressive national governments around the world have started taking action to respond to these environmental concerns. This book discusses the issue of food and water security in India under the context of climate change. It provides information to scientists and local government to help them better understand the particularities of the local climate. It offers insight into the changes to natural ecosystems which have affected the local Indian population. Climate change is one of the biggest challenges to Indian society. It can lead to serious impacts on production, life and the environment. Higher temperatures and sea level rise can lead to flooding and cause water salinity problems which bring about negative effects on agriculture and high risks to industry and socio-economic systems in the future.

This book provides the most recent understanding about climate change and its effects on agriculture in India. Further in-depth research is showcased regarding important allied sectors such as horticulture and fisheries, and examines the effect of climate change on different cereal crops. The individual chapters discuss the different mitigation strategies for climate change impacts and detail abiotic and biotic stresses in relation to climate change. The book provides an insight into environmentally safe and modern technologies approaches such as nanotechnology and utilization of underutilized crops under a changing climate. This book provides a solid foundation for the discussion of climate resilience in agricultural systems and the requirements to keep improving agricultural production. This book is an excellent resource for researchers, instructors, students in agriculture, horticulture and environmental science.

The IDSA Working Group on Security Implications of Climate Change for India felt that while it would be proper to oppose the securitisation of climate change, it would be prudent not to ignore its likely security dimensions. The Working Group Report identifies India`s key vulnerabilities. Future projections of surface warming over India indicate that the annual mean area averaged surface warming is likely to be between 2 degrees and 3 degrees celcius and 3.5 and 5.5 degrees celcius by the middle and end of 21st century respectively. Trends in sea level rise indicate a possible rise between 1.06 to 2.75 mm per year. Every 1.0 degree rise in temperature would reduce wheat production by 4 to 5 million tonnes. Water scarcity will threaten food supplies in India. A quarter of our biodiversity could be lost. The Working Group felt that climate change cannot be delinked from the overall energy security and economic growth. The National Action Plan on Climate Change is a good beginning but its time-bound implementation needs to be ensured. India needs to improve energy efficiency in the industrial, household and transport sectors. The Working Group also looked at the possible adverse impact on the strategy and tactics of Indian armed forces. India should use climate change as an opportunity to make socio-economic development more sustainable.
