The Context
Less fertile land due to land degradation
Less rural labor due to HIV/AIDS and endemic diseases
Increasing levels of pollution, e.g., acid deposition and tropospheric ozone
Climate change, i.e., more extreme events and increasing climate variability will:
- reduce agricultural productivity in the tropics and sub-tropics
- change the functioning of ecological systems
- adversely affect human and animal health, and
- decrease biodiversity
Increasing controversy over the environmental and social acceptability of various agricultural policies, practices and technologies
