Module Aim and Orientation

Irrigation is an important means to improving agricultural productivity, but in many developing countries, the potential for irrigated agriculture has not been realized. While irrigation bears obvious benefits, it is not without substantial impact on the environment (and by extension societies and economies dependent on this environment). Numerous technologies and approaches have therefore been developed to minimize the negative environmental and socio-economic effects. This IRRIGATE Module provides an introduction to the complexities surrounding irrigation. It is part of the Toolbox on Solar Powered Irrigation Systems (SPIS) (GIZ FAO, 2017), which comprises further modules and complimentary tools relevant to informed decision making around SPIS. read more

Furthermore this module is supplemented by two Excel-based tools:

• IRRIGATE – Soil Tool for determining an appropriate irrigation schedule for selected crops and calculate water storage capacities
• IRRIGATE – Impact Assessment Tool for reviewing and weighing socio-economic and environmental impacts of an SPIS project

Chapters

1. Introduction
2. Understand water resources
3. Assess environmental and socio-economic impacts
4. Calculate water requirements
5. Select field irrigation method
6. Plan intake structures, conveyance and distribution
7. Irrigation efficiency tips

Supplementary Tools

• PROMOTE & INITIATE – Impact Assessment Tool
• IRRIGATE – Soil Tool
