It's clear from the passage that, several decades ago, Afghanistan ----.

Afghanistan's terrain, climate and tradition of
gardening make it a good place for growing fruit. In
the 1970s, export of fruits and nuts provided about
40 % of the country's foreign exchange. About 60
% of the world's dried fruit came from Afghanistan.
In the 1990s, the Food and Agriculture
Organization (FAO) helped to create over 300 fruit
- tree nurseries throughout the country to replace
orchards destroyed during a decade of occupation
by the Soviet Union. Further fighting ruined more
of Afghan agriculture, including the vineyards of
the Somali plain. But it was the lack of water and
the lack of money that devastated the country's
orchards, most of which are now in a sorry state.
Such fruits and vegetables that are being
produced now are difficult to distribute or export
because many of the country's roads and bridges
have been destroyed.
