DocumentOther documentWinDASI: A Software for Cost-Benefit Analysis of Investment Projects. Installation Note 2005
Also available in:
No results found.This module contains the WinDASI software and a note that illustrates how to carry out the installation of WinDASI on your personal computer. WinDASI is a software for Cost-benefit Analysis (CBA) of investment projects that allows the analysis of the financial and economic viability of investments. In particular, it facilitates the systematic storage of data for Cost-Benefit Analysis and allows to calculate: a) flows of physical quantities of outputs, inputs and investment items; b) flows of cur rent, discounted and cumulative costs, benefits, and net benefits; c) flows of incremental (With-Without project) current, discounted and cumulative net benefits; and e) indicators of financial and economic viability such as the Net Present Value (NPV), the Internal Rate of Return (IRR), the Benefit/Cost Ratio, (BCR), the Switching Values (SVs) and Sensitivity tests. Instructions are provided on how to carry out calculations for the different components of an investment project, notably: plans, zones and projects (i.e. at different levels of aggregation). In addition, the software can deal with comparisons of different projects and alternative scenarios (e.g. with–project versus without-project), and normal and phased modes of calculation. -
DocumentOther documentWinDASI: a Software for Cost-Benefit Analysis of Investment Projects. Calculations Performed by the Software 2005
Also available in:
No results found.This module illustrates how to carry out cost-benefit calculations of investment projects in WinDASI, after data are inserted in the database. It explains, by means of a step-by step procedure, how to calculate: a) flows of physical quantities of outputs, inputs and investment items; b) flows of current, discounted and cumulative costs, benefits, and net benefits; c) flows of incremental (With-Without project) current, discounted and cumulative net benefits; and e) project indicators such as the Net Present Value (NPV), the Internal Rate of Return (IRR), the Benefit/Cost Ratio, (BCR), the Switching Values (SVs) and Sensitivity Analysis. Instructions are provided on how to carry out calculations for the different components of an investment project, notably: plans, zones and projects (i.e. at different levels of aggregation). In addition, this module addresses normal and phased mode of calculation and comparisons of different projects alternative scenarios (with–project versus without-p roject). -
DocumentOther documentWinDASI: a Software for Cost-Benefit Analysis of Investment Projects. Inserting and Managing Data 2005
Also available in:
No results found.This module explains how data should be organized and entered into the WinDASI software to run Cost-Benefit Analysis (CBA) of investment projects. In particular, as regard as data entry, it illustrates how the “components” window works. After, it shows the facilities the program has to check for mistakes, such as data omitted or entered incorrectly. In the last part of this module, it is explained how to manage project data, such as saving and loading project data.

Book (series)Technical studyThe impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
Background paper for The State of Food Security and Nutrition in the World 2018
2020Also available in:
No results found.Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated. -
Book (stand-alone)Manual / guideProcessing of fresh-cut tropical fruits and vegetables: A technical guide 2010
Also available in:
No results found.There has been a marked upward trend in production and consumption of fruits and vegetables in Asia and the Pacific in recent years. Along with rising consumer demand has come greater awareness of food safety issues and increased need for convenience and quality. Selection of high quality horticultural produce for processing and implementation of good practices during processing operations are required to assure both the quality of the produce and the safety of the final product. This technical guide reviews, from a theoretical and practical perspective, the critical issues that must be addressed for fresh-cut produce to meet consumer demand for convenience, quality and safety. A case study on fresh-cut processing in Thailand is included. The guide should be of practical value to small processors, trainers and extension workers who provide support to individuals engaged in production of fresh-cut tropical produce for sale. -
Brochure, flyer, fact-sheetBrochureStandard operating procedure for soil available phosphorus - Olsen method 2021
Also available in:
No results found.This procedure is suitable for calcareous, alkaline, neutral, and slightly acidic soils containing CaPO4, since the calcium concentration in the solution is suppressed by the precipitation of CaCO3, increasing PO4 concentration in solution. Neutral and slightly acid soils (pH 6.0 to 7.0) may contain both Ca- and Al-phosphates. The NaHCO3 extractant can remove Ca-phosphates and phosphate adsorbed on the surface of calcium and magnesium carbonates along with Al-phosphates and is considered the most suitable extractant for these soils.
