Match each environmental conservation technique listed on the left with its primary operational objective or environmental management function on the right.
- TerracingMitigation of surface runoff and soil erosion on steep, hilly slopes by breaking continuous slope length
- Taungya systemIntegration of temporary food crop farming with tree cultivation to re-establish degraded forest cover
- Effluent treatmentNeutralization and purification of industrial liquid waste prior to discharge into aquatic ecosystems
- ShelterbeltsEstablishment of dense tree rows perpendicular to prevailing winds to arrest desert encroachment and wind deflation
Answer
Terracing matches with mitigating surface runoff and soil erosion on steep slopes; Taungya system matches with integrating temporary crop farming with tree cultivation; Effluent treatment matches with neutralizing and purifying industrial wastewater before aquatic discharge; and Shelterbelts match with establishing tree rows to arrest desert encroachment and wind deflation.
Each technique targets a specific environmental problem: terracing combats water erosion on steep gradients by altering slope structure; the Taungya system promotes reforestation alongside temporary food production; effluent treatment purifies industrial liquid waste to protect water bodies; and shelterbelts function as windbreaks to halt desert encroachment in arid zones.
