Charting Income Inequality. The Lorenz Curve. EASYPol Series 000

This analytical tool explains how to build Lorenz Curves for income distributions and discusses their use for inequality measurement. A short conceptual background, a step-by-step procedure and a simple numerical example illustrate how to calculate and draw Lorenz Curves. A discussion on the use of Lorenz Curves to represent inequality is also provided. It highlights that the Lorenz Curve is one of the most used ways of representing income distributions in empirical works thanks to its immediate comparability with a “natural” benchmark, the Equidistribution line, representing the most egalitarian distribution. The concepts of Lorenz dominance and intersection of Lorenz Curves [...]

Facing the Challenge of an HIV/AIDS epidemic: Agricultural Extension Services in Sub-Saharan Africa

The mandate of extension services, whether public or private, has always been rural human resources development with an aim to increase food production through the introduction of improved agricultural technology. The very survival of these human resources, both within the extension organization and among the clientele, however, is currently at stake due to the HIV/AIDS menace. Urgent and major efforts are needed by the extension services to prepare themselves for battle against the epidemic, to educate the farming population about the disease, and to develop new strategies, methodologies, materials, technology and equipment to serve the extension needs of thousands of [...]



Analysing Service Provision. Instruments for Development Cooperation Illustrated by Examples from Irrigation

The irrigation sector of development co-operation experiences considerable difficulty in delivering its services to water users on an efficient, sustainable and ecologically-sound basis. Investments have often failed to "pay off" as expected, and many newly constructed irrigation systems are under-utilized. In the first chapters, the background to the problem, definitions of the term "service", and the special features of non-commercial services are examined. Service analysis in complex organizational structures, and methods and instruments to identify and analyse the many and various services and service relationships are described. The analysis of governance modes for service provision is given in detail, and [...]
