Agr ometeor ology

Principles and Applications of Climate Studies in Agriculture

EVALUATIONS

Pr e-publication REVIEWS, COMMENT ARIES,

“M avi and Tupper ar eto be con- gratulated for pr oducing a very wide-ranging book that delivers an information-rich overview of applications and contemporary issues faced by agr ometeor ology . They have focused on the explanation and application of principles, often thr ough the pr esentation of real and practical examples, ren - dering the contents accessible to a br oad audience. This book should pr ove a useful refer ence, particularly for spe - cialists fr om aligned disciplines and university students undertaking agri - cultur e-r elated courses.”

Stephen Lellyett Deputy Regional Director NSW, Commonwealth Bureau of Meteorology, Darlinghurst, Australia

“T his book will be of gr eat help to students, scientists, and resear ch workers. It pr ovides vast information on the importance, availability , and general use of meteor ological data/services in connection with the planning of agricultural investment and development pr ojects. The authors have done a commendable job by collecting the latest information on existing meteor ological scenarios for pr oject implemen - tation as well as for futur e planning concerning additional investment in development pr ojects. Many books and journals contain fragmented informa - tion on these topics but the authors of this book have pr esented all the infor - mation under one umbrella.”

Mor e pr e-publication

“T he vagaries of the weather im- pact gr eatly on mankind, affect - ing our health, temperament, and living standar ds. Mavi and Tupper have as - sembled a gr eat deal of useful informa - tion to help readers better understand how weather and climate impact on farming systems and influence cr op and pastur e yields and livestock pr oduc - tion. The book is replete with inter est - ing examples and case studies to show how better knowledge of agr ometeo - rology and better access to climate recor ds, short-term weather for ecasts, and seasonal outlooks can impr ove strate - gic and tactical decision making on farms—ther eby enabling managers to incr ease the pr oductivity , sustainability , and financial viability of their agricultural systems. Valuable insights ar e pr ovided into how climate change is likely to impact on dif fer ent regions thr oughout the world, and how the impacts of such change may be reduced. This publication will be valued by farmers, students, scientists, policymakers, and rural and urban commu - nities in developed and developing countries throughout the world.”

David H. White, PhD Director, ASIT Consulting, Canberra, Australia

“T his book is a welcome and neces- sary addition to keep those in - volved in agricultur e and other related industries up-to-date with climate sci - ence developments and their applica - tions. The major str ength of this book is that it brings together principles that ar e globally relevant with the latest sci - entific literatur e on subjects that in - clude agr ometeor ology , the use of cli - mate information in agricultur e, solar radiation and its role in plant gr owth, envir onmental temperatur e and cr op pr oduction, and climatological meth - ods for managing farm water resour ces. Irecommend this book to edu - cators and those with an inter est in applied climate science and agricul - tur e.”

David George, BSc, GDipEd, MAppSc Scientist (climate applications and education), Queensland Department of Primary Industries

“T his compr ehensive book meets an incr easing need for those inter ested in climate and weather ,such as agricultural resear chers, advisors, and policymakers. The authors use their international experience to apply the principles of climate and plant science to practical management of agricul - tural systems—fr om the policy issue of dr ought assistance to managing pests in the field. The principles of agr ome - teor ology have never been mor e im - portant as we manage agricultur ethat is pr oductive and sustainable in a vari - able and changing climate. This book is valuable not only as a university text but also as a useful refer ence text for pr ofessionals involved in the interface between climate and agriculture.”

Mor e pr e-publication

“A gr ometeor ology is mor e in de- mand than ever , and this book will be an important resour ce for ques - tions on how climate and weather im - pact on agricultural pr oduction. The authors have used their extensive expe - rience to harvest examples and extract principles acr oss a diverse but repr esentative range of agricultural pr oduc - tion systems. Thr ough an inter disciplin - ary perspective, they have achieved a very useful distillation of principles by reviewing applications in agricultural management. The eleven chapters in - clude thor ough reviews on how climate and weather determine effective rainfall, on dr ought , climate change, and on the incidence of many pests and parasites. The book’s focus is on analysis and applications, and it is a valuable resour ce for both students and managers.”

Barry J. White, PhD National Coordinator (Climate Variability R&D Program), Land & Water Australia

“T his book pr ovides a wide variety of perspectives and extensive ex - amples of tools and pr ocedur es to man - age and make the most of both shortterm weather and longer -term climate variability . This very readable book should be useful to a br oad range of practitioners fr om farmers to resear ch scientists.”

Earlier , he was Professor of Agrometeorology at Punjab Agricultural Uni versity in India where he taught climatology and agrometeorology for over tw o decades. Dr. Ma vi has been the re - search supervisor of twenty postgraduate students majoring in agrometeorology . In addition, he has been on the research advisory committee of scores of students majoring in agronomy , soil science, soil and water engineering, entomology , plant pathology , and botan y. He has advised numerous indi viduals and or ganizations in climate-related risk management.

Mr. Graeme J. Tupper is Technical Specialist, Resource Information, in the NSW Department of Agriculture, Australia. His work in - volv es research, de velopment, and service projects in the application of spatial information technology to agriculture. Specif ic projects include monthly rainf all “drought” mapping, fire and flood mapping and monitoring, monitoring endemic li vestock diseases, weed detection and mapping research, and water reform structural adjustment mapping. Mr. Tupper is an agricultural scientist and has work ed in this capacity in research, academic, and extension institutions in Aus - tralia, Papua Ne w Guinea, South Africa, and the United States, in en - vironments ranging from semi-arid rangelands through temperate to tropical agriculture.
