War and deforestation in Sierra Leone IOPscience

2015-9-24  Total forest cover in Sierra Leone chiefdoms declined by an average of 9.6 percentage points, from 67.5 percent covered to 57.9 percent covered, across the period of the war (table 1; figure 2). This downward trend in forest cover was accounted for entirely by changes in secondary forest cover, which accounts for most forest cover in Sierra Leone: average secondary forest cover dropped from

All the cockle beds examined were exploited and had stocks with a mean density of ≤9 large (>10 mm) cockles/m2, and at River No. 2 estuary at peak spatfall, of 130 seed cockles/m2. Spat settlement began in November-December after the rainy season, reached a peak in January-February and continued to the early part of the following rainy season (May-June).

1986-3-1  Laboratory testing of 96 (150×150 mm) concrete cube specimens were performed to study the effect of aggregate variation on the strength of laterite concrete. The different investigations were carried out using granite gravel as coarse aggregate and lateritic sand as fine aggregate. The best proportions between laterite and 20 mm gravel were
