the beginning of the 1990s, was favorable for many European countries
with positive anomalies. Like for Bulgaria during this period, drought
(causing 15% or more reduction in yields) was practically absent. The
exceptions were only five years: 1979 for Austria, 1991 for Albania, 1993
for Hungary, 1990 for Greece, and 1974 for Malta. Yield anomalies were
negative after the mid-1990s.

A frican Mediterranean and Near East

Figure 34.4 shows wheat yield variation for some African Mediterranean
and Near East countries during 1967-95. The yield trend was characterized
mainly by negative anomalies. Frequent droughts (causing yield reduction
exceeding 20% of the normal) occurred in 1970, 1978, 1983, 1984, and
1985 in Yemen; in 1970, 1971, 1973, 1977, 1979, 1984, and 1989 in Syria;
