This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2 and 4°C warming, and predict 13, 38 and 63% reduced inflows. Impact on irrigated agricultural production and profitability are estimated with a mathematical programming model using a two-stage approach that simultaneously estimates short and long-run adjustments. The model accounts for a range of adaptive responses including: deficit irrigation, temporarily following of some areas, permanently reducing the irrigated area and changing the mix of crops. The results suggest that relatively low cost adaptation strategies are available for a moderate reduction in water availability and thus costs of such a reduction are likely to be relatively small. In more severe climate change scenarios greater costs are estimated. Adaptations predicted include a reduction in total area irrigated and investments in efficient irrigation. A shift away from perennial to annual crops is also predicted as the latter can be managed more profitably when water allocations in some years are very low.

Freshwater scarcity is a critical challenge, with social, economic, political and environmental consequences. Water crises in Australia have already led to severe restrictions being applied in cities, drought ravaging farmlands, and the near-terminal decline of some rivers and wetlands. A Water Story provides an account of Australian water management practices, set against important historical precedents and the contemporary experience of other countries. It describes the nature and distribution of the country's natural water resources, management of these resources by Indigenous Australians, the development of urban water supply, and support for pastoral activities and agricultural irrigation, with the aid of case studies and anecdotes. This is followed by discussion of the environmental consequences and current challenges of water management, including food supply, energy and climate change, along with options for ensuring sustainable, adequate high-quality water supplies for a growing population. A Water Story is an important resource for water professionals and those with an interest in water and the environment and related issues, as well as students and the wider community.

Climate projections for the Lower Murray catchment estimate elevated temperatures and a decline in rainfall and runoff (Connor et al.,2008), which is very likely to affect agricultural systems. The negative impacts can be mitigated through adaptation, which requires involvement of the local community (Klein et al., 2007), and hence, it is important to gain a better understanding of farmers’ perceptions to climate change, the adaptation options to the current drought circumstances and what limits their actions upon droughts and climate change. The data is collected through a phone-survey in which 43 farmers participated. Although the number of participated farmers is not sufficient to generalize the results beyond this sample population, general trends were identified for further evaluation. The interviewed farmers are aware of variations in climatic conditions, but are inclined to connect these to the natural climatic variability, rather than to human-induced climate change. Adaptation to the current drought exists mainly of purchasing extra water rights and/or improving irrigation efficiency. Factors which influencing farmers perceptions toward climate change and their ability to adapt, are their age, education level and the district where they are living in. Younger farmers tend to be aware of climate change and the impacts on their farm business, while older farmers appear to link this to natural climatic variability. Farmers who have been on university or have followed TAFE are more likely to respond than farmers who have been only on primary school. In addition, farmers who are living in Kingston OM are more likely to adapt to climate change. The main barriers for adaptation to climate change considered by farmers are the lack of financial incentives, their strong dependency on commodity prices and the lack of knowledge on future water availability and adaptation options. This study suggests that the adoption of climate change adaptation measures can be accelerated by financial incentives that reduce the financial risks of the individual farmers and by providing more information about the future climate change impacts and adaptation possibilities.

Ô. . . this book is a very useful resource for the lawyer. . . makes a good start by presenting a wide-ranging portfolio of multidisciplinary research that will assist in progressing the task, challenging though it may be.Õ Ð Chris Rodgers, Environmental Liability This book explores the interaction between climate change and the agriculture sector. Agriculture is essential to the livelihood of people and nations, especially in the developing world; therefore, any impact on it will have significant economic, social, and political ramifications. Scholars from around the world and from various fields have been brought together to explore this important topic. The contributions found here analyze direct agronomic effects, the economic impacts on agriculture, agricultural impacts on the economy, agricultural mitigation, and farmer adaptation. The authors argue that climate change is likely to have an extensive impact on agriculture around the world through changes in temperature, precipitation, concentrations of carbon dioxide, and available water flows. This thorough and timely volume is an invaluable resource for anyone interested in exploring the impacts of climate change in arguably the most important sector of the world economy. Economists, agronomists, and climate modelers in academia and the public sector, policy analysts and development agency staff, and graduate/postgraduate students will find this remarkable volume a welcome addition to their collection.

Murray-Darling Basin, Australia: Its Future Management is a much-needed text for water resources managers, water, catchment, estuarine and coastal scientists, and aquatic ecologists. The book first provides a summary of the Murray-Darling River system: its hydrology, water-related ecological assets, land uses (particularly irrigation), and its rural and regional communities; and management within the Basin, including catchments and natural resources, water resources, irrigation, environment, and monitoring and evaluation. Additionally, the recent major water reforms in the Basin are discussed, with a focus particularly on the development and implementation of the Basin Plan. Murray-Darling Basin, Australia: Its Future Management then provides an analysis of the next set of policy and institutional reforms (environmental, social, cultural and economic) needed to ensure the Basin is managed as an integrated system (including its water resources, catchment and estuary) capable of adapting to future changes. Six major challenges facing the Basin are identified and discussed, particularly within the context of predicted changes to the climate leading to an increased frequency of drought and a hotter and dryer future. Finally, a ‘road map’ or ‘blueprint’ to achieve more integrated management of the Basin is provided, together with some ‘key lessons’ of relevance to others involved in the management of multijurisdictional river Basins. Provides a consolidated account of the Murray-Darling Basin system; an area of global relevance to those interested in rebalancing river systems where the water resources have been over allocated Offers a detailed analysis of the current system and its management, with a focus on water and ecosystem management Discusses a number of key challenges, particularly those related to climate change, facing future reforms to the Murray-Darling Basin Plan Provides a blueprint for changes needed to ensure the Basin is managed as an integrated whole (from catchment to coast)

In Asia and the Pacific, climate change is now a well-recognised risk to water security but responses to this risk are either under reported, or continue to be guided by the incremental or business as usual approaches. Water policy still tends to remain too narrow and fragmented, compared to the multi-sectoral and cross-scalar nature of risks to water security. What’s more, current water security debates tend to be framed in discipline specific or academic ways, failing to understand decision making and problem-solving contexts within which policy actors and partitioners have to operate on a daily basis. Much of the efforts to date has focussed on assessing and predicting the risks in the context of increasing levels of uncertainty. There is still limited analysis of emerging practices of risks assessment and mitigation in different contexts in Asia and the Pacific. Going beyond the national scales and focussing on several socio-ecological zones, this book captures stories written by engaged scholars on recent attempts to develop cross-sectoral and cross-scaler solutions to assess and mitigate risks to water security across Asia and the Pacific. Identifying lessons from successes and failures, it highlights management and strategic lessons that water and climate leaders of Asia and the Pacific need to consider. This book showcases reflective and analytical thought pieces written by key actors in the climate and water spaces. Several critical socio-ecological zones are covered – from Pakistan in the west to pacific islands in the east. The chapters clearly identify strategies for improvement based on the analysis of emerging responses to climate risks to water security and gaps in current practices. The book will include an editorial introduction and a final synthesis chapter to ensure clear articulation of common themes and to highlight the overall messages of the book.
