Mapping drought patterns and impacts: a global perspective by Nishadi Eriyagama,V. Y. Smakhtin,Nilantha Gamage Pdf

The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.

Renewing Local Planning to Face Climate Change in the Tropics by Maurizio Tiepolo,Alessandro Pezzoli,Vieri Tarchiani Pdf

This book is open access under a CC BY 4.0 license. This book aims to inspire decision makers and practitioners to change their approach to climate planning in the tropics through the application of modern technologies for characterizing local climate and tracking vulnerability and risk, and using decision-making tools. Drawing on 16 case studies conducted mainly in the Caribbean, Central America, Western and Eastern Africa, and South East Asia it is shown how successful integration of traditional and modern knowledge can enhance disaster risk reduction and adaptation to climate change in the tropics. The case studies encompass both rural and urban settings and cover different scales: rural communities, cities, and regions. In addition, the book looks to the future of planning by addressing topics of major importance, including residual risk integration in local development plans, damage insurance and the potential role of climate vulnerability reduction credits. In many regions of the tropics, climate planning is growing but has still very low quality. This book identifies the weaknesses and proposes effective solutions.

Applications of Space Techniques on the Natural Hazards in the MENA Region by Mashael M. Al Saud Pdf

This book introduces a comprehensive understanding in the use of space techniques in natural hazards and risk management in the MENA Region. The book is based on different case-studies from 25 MENA countries, and will be useful in highlighting the issues from all aspects. In recent years the number of natural hazard events has increased in the MENA Region. This is exacerbated by the changing climate and extreme climate events, as well as a large increase in the population in this area. Disastrous events occur on a yearly basis characterized by a vulnerability of physical processes. Floods, earthquakes, and mass movement result in severe damage to property and livelihoods, and have devastating effects upon the environment. These events cause severe financial losses, which on an annual basis, can exceed millions of dollars. The predication, assessment and monitoring approaches remain inadequate in managing these hazards and in mitigating their impacts, but with the development of space techniques and geo-information systems, these situations can now be better managed. The miscellany of satellite images, with different spatial and temporal resolutions, enable the detection of terrain features and provide indications of potential natural risks. This book will of interest to stakeholders, including field experts, academics, researchers and decision makers.

Impacts of climate change on water resources and agriculture in Sri Lanka: a review and preliminary vulnerability mapping. by Eriyagama, N.,Smakhtin, V.,Chandrapala, L.,Fernando, K. Pdf

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their heavy reliance on primary agriculture.

Resources, Services and Risks by Mathew Kurian,Reza Ardakanian,Linda Gonçalves Veiga,Kristin Meyer Pdf

This book discusses the role of observatories in supporting evidence-based decision-making. The book focuses on issues of data accessibility, monitoring frameworks and governance processes with regard to environmental resources – water, soil and waste. This publication highlights challenges related to policy-implementation measures and examines current monitoring approaches, and illustrates how the UNU-FLORES Nexus Observatory seeks to overcome concerns related to data, monitoring and governance of water, soil and waste resources. In particular, given that extreme weather events such as droughts and floods are predicted to become more frequent in the future, it discusses the need for improved hazard risk monitoring. It proposes risk indices for drought and floods, which measure exposure and vulnerability to the phenomena through a multitude of bio-physical, socio-economic and institutional indicators. Furthermore, the potential for using openly accessible data made available through observatories in decision-making aimed at improving food security is also discussed. It acknowledges governments as key players in environmental resource management, and recognizes that decentralization reforms, as well as the emergence of information and communication technologies, have significantly changed the role of governments in promoting sustainable development. The book is particularly relevant for decision-makers, donor agencies, practitioners and students with an interest in environmental management who are also keen followers of discussions on the post-2015 monitoring agenda.

The Impacts of Water Infrastructure and Climate Change on the Hydrology of the Upper Ganges River Basin by Luna Bharati,Guillaume Lacombe,Pabitra Gurung,Priyantha Jayakody,Chu Thai Hoanh,Vladimir Smakhtin Pdf

This study assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin (UGB). Furthermore, the PRECIS regional climate model (RCM) was used to generate climate projections for the UGB, with subsequent simulations of future river flows. Results show that the annual average precipitation, actual evapotranspiration (ET) and net water yields of the whole basin were 1,192 mm, 416 mm and 615 mm, respectively. Precipitation, ET and water yields were found to be higher in the forested and mountainous upper areas of the UGB. On an annual average, present-day flows throughout UGB are about 2-8% lower than under naturalized conditions. Dry and wet season flows under climate change (CC) scenario A2 are lower than that under present climate conditions at upstream locations, but higher at downstream locations of UGB. Flows under CC scenario B2 are systematically higher and lower than that under CC scenario A2 during dry and wet seasons, respectively.

Bailout with white revolution or sink deeper?: groundwater depletion and impacts in the Moga District of Punjab, India by Amarasinghe, Upali A.,Smakhtin, Vladimir,Sharma, Bharat R.,Eriyagama, Nishadi Pdf

Moga District in Punjab, India, is a microcosm of the twin story of irrigation-induced growth and stress. The groundwater consumptive water use in agriculture exceeds the recharge by a substantial margin. Rice production contributes to a major part of this difference. The groundwater depletion is so critical that diversifying agriculture is the only way forward for sustainable agricultural growth. Reducing the rice area and intensifying milk production will be a win-win situation for both the farmers and the area reeling with a groundwater crisis.

The Global Water System in the Anthropocene by Anik Bhaduri,Janos Bogardi,Jan Leentvaar,Sina Marx Pdf

The Global Water System in the Anthropocene provides the platform to present global and regional perspectives of world-wide experiences on the responses of water management to global change in order to address issues such as variability in supply, increasing demands for water, environmental flows and land use change. It helps to build links between science and policy and practice in the area of water resources management and governance, relates institutional and technological innovations and identifies in which ways research can assist policy and practice in the field of sustainable freshwater management. Until the industrial revolution, human beings and their activities played an insignificant role influencing the dynamics of the Earth system, the sum of our planet‘s interacting physical, chemical, and biological processes. Today, humankind even exceeds nature in terms of changing the biosphere and affecting all other facets of Earth system functioning. A growing number of scientists argue that humanity has entered a new geological epoch that needs a corresponding name: the Anthropocene. Human activities impact the global water system as part of the Earth system and change the way water moves around the globe like never before. Thus, managing freshwater use wisely in the planetary water cycle has become a key challenge to reach global environmental sustainability.
