Question 5

Engineers in SWC

Answer 5

 Sound SWC is based on full integration of engineering, atmospheric, plant and soil sciences
 Soil physical, chemical and engineering characteristics
 Soil-plant-water-environmental interactions
 Creation of proper environment for optimum plant and animal production
 Rural-urban interface; air and water pollution
 Social and economic aspect; local and national government policies, laws and regulations
 Ground and satellite mapping techniques (GIS), weather record and prediction, soil survey reports, computer
 Numerical simulations (modeling)

Question 6

is one major cause of water pollution

Answer 6

soil erosion

Question 7

Conservation Ethics

Answer 7

 Increasing population will dictate the necessity of conserving land and water resources
 Decreasing population of wildlife, extinction of species-air and water pollution, loss of habitat
 Soil erosion is one major cause of water pollution
 Conversion of prime farmlands to urban development
 Natural resources should be passed on to future generations in as good or better condition than previous generations have left them
 Growing trend of conservation (government incentives, private sector-led, short and long term economic benefits)
 Recycling of paper, glass, metals, etc.
 Waste segregation; plastic ban
 Increasing costs of waste disposal
