An analysis of the agro-ecological regions conducted
for the period 1940 to 2000 shows that Region I,
which receives the lowest rainfall, has been expanding
northwards over the years (Siampale, 2008).
Figure 2.6
Zambia is classified into three agro-
ecological regions: Region I covers the Zambezi
and Luangwa valleys, Region II covers the central,
western and eastern parts of the country and
Region III covers the northern parts of the country.
The regions are also referred to as:
• Low rainfall areas (
less than 800mm
);
(Region I and IIB)
• Medium rainfall areas (Region IIA)
(
800mm- 1,000mm
)
• High rainfall areas (Region III)
(
above 1,000mm
)
