Identification of Drought Resistant Vegetation (i-Drive) is a quick, practical, and inexpensive method developed to design a recommendation of reclamation strategy on Hambalang quarry, with main focus on the vegetation resistance to drought stress.

The i-Drive steps are (1) preliminary survey, (2) identification of vegetation on the land surfaces of flat, concave, and convex areas, (3) quantification of nitrogen-fixing bacteria and phosphate-solubilizing bacteria from the soil around the vegetations, and soil chemical properties, (4) determination of the vegetation resistance to drought stress, (5) recommendation mapping of the land reclamation strategy. The recommendations on land reclamation strategy using revegetation will accelerate the soil fertility improvement, thus becoming an effective, efficient, and economical, mainly related to an increase in biodiversity.

The drought-resistant vegetations are estimated to be varies from the level of the trees, poles, saplings, seedlings, and ground cover. In addition, the development of the alley cropping model between legume trees/shrubs along local nitrogen-fixing and phosphate-solubilizing bacteria can reduce the fertilizers needed to cultivate grasses for potential alternative energy crop. These potentials will certainly attract shareholders and stakeholders, particularly the farmers to raise concerns to re-vegetate together, thereby contribute to company cost efficiency of the land reclamation.
