3 The Agricultural Sector<br />

available arable land for each category; as well<br />

as the average amount of total cultivated area per<br />

year and its percentage in terms of total arable<br />

land (also per category).<br />

The different agricultural areas described<br />

above determine the choice of crop mix (mainly<br />

depending on natural soil fertility and the<br />

availability of irrigation water) 23 .<br />

The Uplands<br />

The uplands represent almost 80% of total<br />

arable land. They are less fertile and less apt<br />

for agriculture on a sustainable basis than the<br />

lowlands. Upland soils are largely feralitic, highly<br />

leached with low fertility, extending from the<br />

savannah grasslands in the North to the tropical<br />

rain forests in the South and East. The land is<br />

suitable for the permanent production of tree<br />

crops (such as cocoa and coffee) grown in the<br />

forested areas in the South and East of the country<br />

and food crops, such as rice, cassava, maize,<br />

sweet potatoes, and vegetables) (GoSL 2005b).<br />

The tree crops of major economic importance<br />

are cocoa, coffee and oil palm. Oil palm is<br />

considered a subsistence crop, while coffee and<br />

cocoa are grown only for export. Large-scale<br />

plantations are not common and the majority of<br />

farmers have undertaken tree crop plantations<br />

with holdings ranging from 1 to 5 ha (MAFFS<br />

& MFMR, 2004). The tree crop plantations<br />

are developed under the shade of natural<br />

vegetation. In general, old plantations which<br />

were abandoned during the war are currently<br />

under rehabilitation, instead of establishing new<br />

plantations (field observation by project team).<br />

This is mainly due to the high sunk costs related<br />

to planting new trees which have substantially<br />

larger growing periods. Thus, cocoa and coffee<br />

plantations, mostly grown in the forest ecosystems<br />

that are predominant in the Eastern region of the<br />

country, tend to be low in productivity. In the<br />

23 A. Lakoh, (Njala University, 2010) and FAO – IFAD (2006), Rural<br />

Finance and Community Improvement Programme (RFCIP).<br />

Northern region priority is given to palm, but<br />

also to citrus, mango and other fruit trees. Only<br />

minimal processing of cocoa beans takes place<br />

within the country prior to export. In the first<br />

instance, farmers leave the beans to ferment for<br />

5-6 days either on the ground or in large rattan<br />

baskets, dried, and finally bagged. Small-scale<br />

farmers do not have access to mechanical hullers.<br />

As for the processing of coffee, the cherries are<br />

sun-dried and the beans hulled manually in the<br />

main growing areas. The bulk of oil is processed<br />

traditionally with a labour-intensive system (field<br />

observation by project team).<br />

In the uplands, shifting cultivation of food<br />

crops, (i.e. mainly rice) are grown on mixed plots<br />

in the first year following clearing of bush fallow.<br />

Upland slash and burn cultivation includes many<br />

stages before harvesting and storage, with the<br />

overall labour requirements for an entire cycle<br />

of these cropping operations amounting to 185<br />

man-days/ha on average (MAFFS & MFMR,<br />

2004). As described earlier in this section, after<br />

a crop cycle of 2-3 years, the land is then left to<br />

lay fallow in order to regenerate forest, organic<br />

matter, soil structure and nutrients. Due to<br />

increasing population pressure resulting from the<br />

traditional land tenure system, changes in the<br />

economic situation and technological progress,<br />

the idle intervals have progressively shortened<br />

from an average of 20 years in the 1960s to<br />

approximately 4-7 years in recent years (NSADP,<br />

2009). As a consequence, soils in the uplands are<br />

systematically becoming less fertile.<br />

The Lowlands<br />

The lowlands are more fertile and present a<br />

considerable potential for intensive cultivation.<br />

The maximum lowland area cropped in one year<br />

has been reported to be about 170,000 ha in<br />

1995 (MANR&F, 1996).<br />

In the lowlands rice is the dominant crop<br />

(since most of the other crops cannot tolerate the<br />

waterlogged conditions). Rice is also the main<br />

staple crop for over 90% of the population in
