Book Description
This paper presents a synthesis of 15 success stories in the production, processing, and marketing of high-value food products (HVF) in developing countries in Asia, Latin America, and Africa. High-value food products, such as fresh and processed fruits and vegetables, meats, fish, dairy products, and vegetable oils, are defined as having high intrinsic value or a high rate of value added through processing. Trade in these products has expanded while trade and prices for other agricultural products, such as most staple crops, have stagnated or declined. The growing trade in HVF has prompted policymakers in developing countries to examine more closely how they can expand and diversify their exports of these products. This study explores the technical, organizational, and commercial challenges facing those in HVF export development. It identifies common market and institutional factors that have contributed to the growth and international competitiveness in HVF trade. Particular note is made of the roles of the private and public sectors and of the effect of the policy environment. It examines the effect of institutional coordination on the stages of production, processing, and trade. An annex summarizes 12 case studies of the development and performance of food commodity markets. It includes export of fresh vegetables from Kenya in the 1960s, shrimp from Thailand in the 1970s, and processed tomatoes from Chile in the 1980s.

Book Description
This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.

Book Description
This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.
