IRMA combines irrigation suitability with development needs and expected benefits, giving planners a framework for comparing areas before committing resources.
A new FAO digital platform is intended to help countries decide where irrigation investment makes sense, bringing the physical potential of land and water together with development priorities and expected benefits.
The Food and Agriculture Organization announced the IRMA platform through its Land and Water programme on 13 October and highlighted it again in its World Food Forum reporting on 15 October. It is hosted within FAO’s Agro-Informatics Platform.
The global interface is openly accessible, while more detailed country platforms are developed with national counterparts. The announcement does not establish a completed South African implementation or a farm-specific investment recommendation.
Three questions before expansion
IRMA stands for the Mapping of Irrigation Potential and Needs Initiative. Its starting point is that a location’s physical suitability is only part of the case for developing irrigation.
In a technical explanation, FAO specialists Maher Salman, Eva Pek and Camilla Simongini describe three analytical components: whether irrigation is physically suitable, where it responds to development needs, and whether it can deliver sustainable benefits.
The first considers factors such as water, soils, terrain and climate exposure. The second connects potential development with needs including food security and resilience. The third examines the expected returns over time.
The framework combines the assessments to help rank areas. This gives planners a way to compare options using a consistent set of questions, rather than relying only on a map showing where crops might grow under irrigation.
FAO’s technical account also describes a baseline of irrigated and rainfed land that draws on satellite information, local knowledge and artificial intelligence. National experts are intended to help adapt and maintain the analysis.
Country work predates the launch
The digital launch follows earlier work on the initiative. FAO reported a national workshop in Jordan on 22 July, involving the Jordan Valley Authority, agricultural and water institutions, and development partners.
That workshop introduced the methodology and discussed its application to national planning. It illustrates the distinction between making a global platform available and doing the detailed work required within a country.
The Jordan report describes the intended use of the framework; it does not provide an independently measured result showing how much water or money the system has saved. Similar evidence would be needed before claiming a proven benefit in another country.
Water governance remains part of the decision
In his 15 October remarks at the Rome Water Dialogue, FAO Director-General Qu Dongyu placed irrigation planning within a wider discussion about water governance. His priorities included efficiency, fair access, preparedness for droughts and floods, and the protection of ecosystems that sustain water supplies.
The organisation also promoted reducing demand, reusing and recycling water, and replenishing resources. That wider approach matters because allocating investment and allocating water are connected decisions with consequences for other users.
For South African readers, a planning platform therefore needs to be considered alongside the country’s own authorisation arrangements. The Department of Water and Sanitation describes several routes for lawful water use, including general authorisations, existing lawful use and licences.
A favourable planning assessment does not itself grant a water entitlement. The applicable authorisation, local availability and project requirements still need to be established for the proposed use.
From a priority map to a workable project
The practical value of IRMA will depend on the information used and how decision-makers apply it. A high-priority area can justify closer investigation, but it does not settle every question about a particular farm, scheme or investment.
For example, a planner would still need to connect the identified opportunity with reliable local water information, infrastructure requirements and a realistic operating plan. Those are project decisions beyond the announcement of a global mapping tool.
The platform’s immediate contribution is a shared framework for comparing suitability, need and benefit. Evidence from country applications and independently assessed outcomes will be the next step in judging how effectively it supports irrigation investment.
