A group of renowned scientists and experts issued a declaration at the Stockholm Water Week on the importance of rainwater management in eradicating poverty and hunger.
Hydraulic professor Malin Falkenmark (top photo) of the Stockholm Resilience Centre addressed the statement and showed two maps (see above) illustrating the areas in the world with malnutrition (right) and the semi-arid Savanna zones (left). “They are converge”, said Falkenmark, “so in these areas rainwater is the key to eradicate hunger and poverty.”
The Savanna zones are characterized by highly valuable but unpredictable rainfall, causing floods in the rain season and drought in the dry season. For the 2 million small farmers in these areas rainwater is the main water resource. Better utilisation of the rainwater, can increase their productivity from 1 ton per hectare to a potential 5 ton, clarified the Swedish professor.
Smart solutions to buffer rainwater
At the same time the Dutch 3R Partnership launched the booklet Smart 3R Solutions at the Stockholm Water Week.
The concept of 3R is based on recharge, retention and reuse of rainwater – preferable in the underground - as part of integrated river basin management.
The booklet describes six cases, including some in the tropical dry lands, of small farmers in these areas taking simple measures to buffer the rainwater in the wet seasons in order to have an additional harvest in the dry season.
With the better utilised rainwater some farmers could harvest up to three times more.
Pits and stone bunds
Examples of such smart and accessible solutions include the construction of pits on locations where the rainwater runs off. The runoff collects in these pits and then infiltrates in the subsoil recharging the groundwater. Another example is the construction of stone bunds that prevent the rainwater to run off and being retained on the field.
High level panel on Africa
Dr. Ania Grobicki, Executive Secretary of the Global Water Partnership, referred to the Smart 3R Solutions booklet during a high level AMCOW/GWP panel discussion on climate resilience in Africa as “complementary to the declaration since it offers practical climate resilience solutions on a grass root level, particularly in rain-fed agriculture dependent economies”.
The 3R Partnership combines Rain Foundation, Acacia Water, MetaMeta and Aqua for all. The concept has been developed in close cooperation with the International Fund for Agricultural Development (IFAD) and is now being applied in many catchments in the world.

Integration in river basin management
“The 3R concept is developed by land and water specialists working on water projects in arid areas”, explains director Guus Paardekooper of the Rain Foundation at the Stockholm Water Week.
Paardekooper emphasises that on top of the smart individual measures for farmers, the 3R concepts puts land measures also in perspective of the (sub)catchment of a river.
“Here the knowledge of Dutch water management comes in", he says. "When many farmer start buffering their rain water, they influence the local water system and the downstream river discharge. So it is important for the government to coordinate the rain water management, together with all the other water users in the catchment. The 3R approach incorporates this coordination”..
