Forecasting models for yield estimation

Since its establishment, there has been an overwhelming response and over nominations from ICID national committees were received.

So far, 24 awards have been given to the professionals coming from 12 countries across the world. Earlier, a booklet providing primary information about the water saving practices adopted by some of the ICID member countries was published in The document was very well received not only by ICID member countries but by international organizations, as well.

This document is a compilation in a different form. Besides bringing out in a generic sense selected experts across the world have contributed to enhance its contents.

The case studies of successful water savings from Australia, Brazil, China, India, Egypt, Korea, Pakistan, South Africa, Spain, Turkmenistan, and USA are highlighted and as obvious, water saving efforts is more conspicuous in countries having significant irrigated agriculture.

It is hoped that the innovative ideas and practices captured in this compilation would enthuse other countries and ICID's mission to spread 'best practices' would stand accomplished. This book will be a rich source of knowledge and reference work providing an inspiration for those professionals engaged in aspiring 'more and more crop per drop'.

Development and management of irrigation, drainage and flood control play a key role in poverty eradication and increasing the productivity of agriculture in LDCs. This book contains various recommendations towards promoting irrigation and drainage in LDCs of Asia. Worldwide, the use of sprinkler and micro irrigation methods have been steadily increasing in order to cope with declining water withdrawals to irrigation, better use of other farm inputs like - seed, fertilizers and chemicals, energy, etc.

At the same time, these pressurized irrigation technologies should not be considered as a panacea for improved on-farm water management. Experience has shown that if these systems are not designed, operated, and maintained properly, they may not give the expected benefits and even in some situations may adversely affect the crop growth.

It is therefore essential to carry out periodic diagnostic analysis and performance evaluation of the pressurized irrigation systems to ensure that they are operating optimally. Among the pressurized irrigation, micro irrigation technology is expanding by leaps and bounds.

Many new and innovative products are being produced by the researchers and manufacturers. The manual is authored by Dr. Ghinassi has a long and varied field experience in conducting performance evaluation tests of different types of sprinkler and micro irrigation systems.

Although, there are many publications on performance evaluation of on-farm irrigation methods, this manual is different due to its own unique approach.

It provides a comprehensive information both, theoretical and practical; these inter-alia include appropriate performance indicators, field evaluation techniques and factors affecting irrigation systems performance etc. Ghinassi has touched upon the practical aspects and provided minute details on various performance indicators and their field testing.

This Strategy document was further improved, updated and finalised through eight regional visions, 43 country reports and several deliberations within ICID. The usage of micro irrigation is increasing world over, especially in arid and semi-arid regions as an effective water conservation and demand management measure to cope up with the increasing scarcity of water in agriculture.

The micro irrigated area grew gradually from 1. Today, the micro irrigation is practiced in more than 70 countries covering an area of over 6 million ha showing the doubling of area just in the last six years. The book contains 14 chapters and provides information on the latest developments in micro irrigation system components, practical aspects of water treatment and filtration, fertigation, monitoring and control, and maintenance of micro irrigation systems.

Israel has been a pioneering country in the field of pressurized irrigation technology, especially in micro irrigation. Moshe Sne, the author of the book has a vast experience in the planning, designing and implementation of micro irrigation systems. The book has a sizeable illustrations and tables.

The step by step procedure of planning and design of micro irrigation system for variety of crops are given in a scientific manner in a lucid language with some practical examples. This guideline will be a valuable reference book for irrigation engineers, practising professionals in water management, students, farmers, manufacturers and all those dealing with the subject of micro irrigation.

Rainfall events have large seasonal or irregular fluctuations. Upland irrigation, therefore is necessary in humid regions in order to keep the soil moisture at desired level. Intensive cultivation is essential in order to harvest high quality fruits and vegetables, and careful water application via irrigation is very essential.This paper explores the feasibility of using open data and an open source toolbox for ensuring reproducibility in operational performance analysis of air navigation services.

our models are consistent with a variety of stylized facts regarding the yield curve. We use our models to produce term-structure forecasts at both short and long horizons, with encouraging Here we introduce the framework that we use for ļ¬tting and forecasting the yield curve.

We argue that the well-known Nelson and Siegel () curve is.

Prediction or forecasting is a common phenomenon for which all human beings are always eager to know. The pre-knowledge about unknown and uncertain future prepare them to cope up in an efficient way.
