Match each environmental conservation technique on the left with its primary management function on the right.
- AfforestationPlanting trees in previously unforested areas to establish new forest cover and curb erosion.
- TerracingConstructing flat step-like ledges across steep hillside slopes to slow down surface runoff water.
- Contour PloughingPloughing fields horizontally along lines of equal elevation to hold rainwater and prevent topsoil loss.
- RecyclingProcessing discarded waste products into new re-usable materials to minimize resource depletion.
Answer
Afforestation matches with planting trees in non-forested areas; Terracing matches with constructing flat step-like ledges on steep slopes; Contour Ploughing matches with ploughing along lines of equal elevation; Recycling matches with processing discarded waste into new reusable materials.
Each technique directly aligns with its specific ecological objective: Afforestation introduces tree cover to unforested land; Terracing reduces surface runoff velocity on steep hillsides through step-like structures; Contour ploughing creates horizontal water traps along elevation lines; Recycling reduces environmental degradation by turning waste back into raw usable resources.
