How is it abandoned? The whole rest of the article describes how it's more profitable to request charitable aid to facilitate coffee farming than it is to actually do long-term coffee farming. The farmer first depicted doesn't want to cut down his badly-maintained coffee tree precisely because those few fruits it produces lets him legitimately say "I grow coffee, but need money/equipment donations to improve it", garnering cash or sellable equipment that he can proceed to buy food with; if he actually applied those donations to seriously improve his farming, there's no way he can get that tree to produce enough to greater return than just "chasing [and abusing] charity".

You see the point abandoned, I see the point fairly summarizing the entire article.
