Researchers have studied various aspects of the ancient civilization of Sri Lanka and probed deeply into the subject of village tank clusters (tank cascade systems) during the last 4 decades. A wealth of information was gathered and the knowledge of many components has been updated. This book brings you this updated information. The author brings new definitions of tank cascade systems and cascade ecology. The book begins with the historical perspective and moves on to explain various aspects, step by step, such as geography, geology and geomorphology, soil and climate, surface and groundwater, traditional agriculture and water management, flora and fauna, recent studies and the restoration of cascade ecology. The book will interest geomorphologists, geologists, geographers, archaeologists, ecologists, and historians. Specifically, university lecturers, students and researchers will find interest in these pages and may utilize the content to prepare their study materials.

A food system comprises the entire range of actors and interlinked activities related to food production, processing, distribution, marketing and trade, preparation, consumption, and disposal. When a food system operates without compromising the needs of future generations, it is considered to be a “Sustainable Food System.” The present-day food systems in Sri Lanka are diverse, and the natural and physical environment, infrastructure, institutions, society and culture, and policies and regulations within which the food systems operate, as well as the technologies employed, have shaped their outcomes. Agricultural research is a key factor in terms of innovation and technological advances. Innovation has been the main driver of food systems’ transformation over the past few decades and will be critical to addressing the needs of a rapidly growing population in a context of climate change and scarcity of natural resources. In addition, agricultural research must help meet the rising demand for food at affordable prices. Comprising 17 chapters written by specialist(s) in their respective subject-areas, this Contributed Volume on “Agricultural Research for Sustainable Food Systems in Sri Lanka: A Historical Perspective” shares the scientific knowledge accumulated by the National Agricultural Research System of Sri Lanka, including universities, and offers recommendations on how to make food systems more sustainable in order to address the current needs of Sri Lankan society. It presents perspectives on four key thematic areas, namely: (i) Crop and animal production, management, and improvement, (ii) Agro-product processing technologies, (iii) Natural resource management, and (iv) Socio-economic development and agri-business management.

This report on small tank cascade systems is based on a study conducted on seven tank cascades of the Walawe river basin, one of the three main river basins in the Ruhuna benchmark basins selected by the International Water Management Institute (IWMI) for its benchmark basin study.The overall objective of this study is to document the situation of small tank cascade systems in the basin, paying special attention to their evolution under agro-ecological, socio-economic and institutional changes on an unprecedented scale in the country after the introduction of open market economic policies in the 1970s, and thereby to contribute to the existing knowledge on small tank cascades, a key feature of water resources in the Dry zone regions2 of Sri Lanka since time immemorial.

Though conflicts continue to arise over land use and land cover changes, the conversion of forest land to cropland or other land uses such as housing and urban development have been on the rise in recent years. Decisions regarding land use and land cover influence climate change as well as various natural processes. While proper changes can minimize the effects and speed of climatic changes, the continued adverse changes may be accelerating the deterioration of the world’s condition. Examining International Land Use Policies, Changes, and Conflicts presents the latest research on the present status of land use and land cover changes throughout the world in order to determine appropriate land use policies that can protect earth’s present and future condition. The findings of the studies investigate the conflicts behind the land tenure and land uses in different countries of the world and examines existing policies and the reasons behind changes in them. Ultimately, the book provides readers with knowledge on how land can be managed in a sustained manner, how landscape models are helpful for predicting and determining future land uses, how land can be managed with the best architectural measures, and how urban forestry is helpful for better environmental management and adapting or mitigating climate change effects. Land users, agriculturalists, urban planners, policymakers, government officials, researchers, academicians, and students looking to improve their understanding of this topic for better use of land in the future will find this book to be an asset to their current research.

The core of this study involved an examination and analysis of certain key features of the traditional small tank cascade systems: a) the location and design of the systems in the past b) the hydro-system which considers the overall hydrological balance and groundwater conditions c) maintenance and tank use d) tank management and integration with local farming systems.

This open access book documents myriads of ways community-based climate change adaptation and resilience programs are being implemented in South Asian countries. The narrative style of writing in this volume makes it accessible to a diverse audience from academics and researchers to practitioners in various governmental, non-governmental and international agencies. At a time when climate change presents humanity with a gloomy future, the stories of innovation, creativity, grassroots engagement and locally applicable solutions highlighted in this book provides insights into hopeful ways of approaching climate solutions. South Asian countries have been dealing with the impact of climate change for decades and thus offer valuable learning opportunities for developing countries within and beyond the region as well as many western countries that are confronting the wrath of climate induced natural disasters more recently. SANDEE has been a pioneer in the development of research and training in environmental economics and related issues in South Asia and Prof Maler has been throughout SANDEE's history, its mentor, and its strongest supporter. Many young economists in South Asia have significantly benefited from Prof Maler's guidance and inputs. The present volume on “Climate Change and Community Resilience: Insights from South Asia” is a fitting tribute and an excellent reflection of Prof Maler's contributions to the SANDEE programme throughout his association. - Mahesh Banskota, Ph.D. Professor, Development Studies School of Arts, Kathmandu University This comprehensive volume aptly identifies grassroots initiatives as the core of the problem of adaptation to climate change. The analysis of the different experiments is lucid, inclusive, and full of interesting detail. The methodologies used and the subjects covered span a range of frameworks and narratives. Put together, the studies are a fitting tribute to Karl-Goran Maler, who spent years putting his impeccable expertise to use for the cause of enhancing research in South Asia. - Kanchan Chopra, Ph.D. Former Director and Professor, Institute of Economic Growth, Delhi, and Fellow, SANDEE The slow international policy response to climate change elevates the importance of understanding how communities can respond to climate change’s many threats. This unusually accessible volume provides that understanding for South Asia while being relevant to the rest of the world. Its emphasis on research by scholars from the region makes it a wonderful tribute to Prof. Karl-Göran Mäler, who contributed so much to the growth of environmental economics research capacity in South Asia. - Jeffrey R.
