The book presents documentary evidence of the insufficiency of rehabilitation works to close the gap between the irrigation service and actual area irrigated of publicly funded national irrigation systems in the Philippines. It outlines a methodology for formulating a modernisation plan for national irrigation systems with focus on the mostly ungauged, medium to small canal irrigation systems. The proposed methodology adaptively modified some known modernisation concepts and techniques and integrated them in a more holistic framework in the context of changing weather patterns and river flow regimes. It includes in-depth review of rehabilitation works; system diagnosis; revalidation of design assumptions on percolation and water supply; characterisation of system management, irrigation service and demand; and drawing up of options and a vision for the modernised irrigation systems. Central to the proposed modernisation strategy is the logical coherence among the design of physical structures, system operation and water supply so that improvements of irrigation service are possible. The book discusses the development of the proposed methodology and demonstrates its utility in two case study irrigation systems.

Many formal irrigation schemes are performing inefficiently for a number of reasons, among which the poor performance of irrigation institutions is one. Benchmarking may be defined as the identification and application of organisation specific best practices with the goal of improving competitiveness, performance and efficiency of such schemes. These guidelines are neither perfect nor final; rather, they represent the beginning of a long and exciting process of benchmarking in the irrigation and drainage sector.

The purpose of this guide is to provide a better understanding of the concept and practice of entrepreneurship. This guide has been prepared for people who want to start a farm business for the first time and for farmers that want to make changes to their farming systems by introducing high value enterprises directed to the market. This guide can also help extension workers be better able to help farmers develop the skills and spirit of an entrepreneur. It is part of a series of booklets on farm business management designed to help extension workers support farmers.

In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses and, as a sector, irrigated agriculture will have to increase the efficiency and productivity of its water use. This is particularly true for manually operated irrigation systems managed by government agencies, which provide water for a large number of users on small landholdings and represent 60% of the total irrigated area worldwide. --

Agriculture is certainly the most important food supplier while it globally accounts for more than 70% of water used and contributes significantly to water pollution. Irrigated agriculture is facing rising competition worldwide for access to reliable, low cost, and high-quality water resources. However, irrigation as the major tool and determinant of affecting agricultural productivity and environmental resources plays a critical role in food security and environment sustainability. Innovative irrigation technologies and practices may enhance agricultural water efficiency and production, in the meantime decrease the water demand and quality issues. I am very pleased to invite you to submit manuscripts in agricultural irrigation which assess current challenges and offer improvement approaches and opportunities for future irrigation.

Efficient irrigation systems measure and monitor water use. This book helps you makes sure water losses are kept to a minimum, while keeping the crop or pasture growing with no moisture stress. Efficient water storage, water budgeting and water use efficiency are explained in detail. Part One: Meters is about: · different types of meters and their advantages and disadvantages · what to consider when selecting a meter · installation and maintenance for meters. Part Two: Storage and Distribution is an overview of: · the importance of reducing losses from seepage and evaporation · measuring losses · strategies for reducing losses · economic value of the cost of loss reduction. Part Three: Benchmarking and Water Budgeting shows you how to: · use, interpret and process benchmarking data for the collection of seasonal water use efficiency (WUE) · develop a seasonal water budget.

If sustainable management of tropical forests is to be accomplished and deforestation brought under control, the on-the-ground performance of existing forest concessions, along with the allocation of new concessions, will have to be strengthened. This study examines the failures of forest concessions and the loss of tropical forests due to mismanagement during the last two decades. It also emphasizes the potential gains resulting from strengthening the allocation, management, and supervision of concessions by concentrating on improving procedures, introducing performance incentives, and monitoring key performance elements
