When roots become saturated with water due to over-irrigation, it causes death in plant roots. This is called:

• salinization

• desertification

• agroforestry

• waterlogging

When irrigation water evaporates, salts are left behind on the soil surface and can cause plant death or lead to

• soil salinization

• desertification

• waterlogging

• monocropping

One of the advantages to using genetically modified organisms (GMOs) is

• reduce the need for pesticides

• they are not regulated by the government

• the concern about safety to consume

• they can cause food allergies

Because global fisheries have dramatically seen a reduction in fish numbers, this technique has been used recently to supplement that loss.

• monocropping

• IPM

• contour farming

• aquaculture
