Justdiggit research: How local changes can have a global impact

Justdiggit (formerly: Naga foundation), a Netherlands-based foundation, is implementing re-greening interventions over large areas with both local impact, regional spin-offs and atmospheric effects. Justdiggit’s method is to restore degraded lands on a large scale using rainwater harvesting and other techniques to increase soil moisture and water availability.

This leads to an increase of vegetation in these degraded lands. In itself greening has a positive effect since vegetation retains fertile soils, slows down runoff, improves infiltration and cools surface temperatures. If done on a large enough scale these landscape changes also affect local climatic conditions (evapotranspiration, temperature, cloud formation), which in turn have a positive effect on regional climate.

To achieve these large scale effects Justdiggit works on so called ‘Hydrologic corridors’: large regions in which strategic project locations are selected and rehabilitated. These project locations are strategically chosen to maximize their impact on the whole region of the hydrologic corridor. The scientific theories behind the concept of the hydrologic corridor and its impact on the regional climate have been researched and are described in a white paper.
