Falling [commodity] prices have meant that large increases in export volume by commodity producers have not translated into greater export revenues, leading to severely declining terms of trade for many commodity producing countries. When the purchasing power of a country’s exports declines, a country is unable to purchase imported goods and services necessary for its sustenance, as well as generating income for the implementation of sustainable development programs.

In the first case, it would not be correct to say that A's being a triangle caused it to have three sides, since the relationship between triangularity and three-sidedness is that of definition. The property of having three sides actually determines A's state as a triangle. Nonetheless, even when interpreted counterfactually, the first statement is true. An early version of Aristotle's "four cause" theory is described as recognizing "essential cause". In this version of the theory, that the closed polygon has three sides is said to be the "essential cause" of its being a triangle.  This use of the word 'cause' is of course now far obsolete. Nevertheless, it is within the scope of ordinary language to say that it is essential to a triangle that it has three sides.
A dynamical system displays sensitive dependence on initial conditions if points arbitrarily close together separate over time at an exponential rate.  The definition is not topological, but essentially metrical.
