Final answer:
Increased agricultural productivity is not a problem associated with the construction of the Three Gorges Dam. The actual problems include soil erosion, resettlement of communities, and significant environmental impacts.
Step-by-step explanation:
The problems associated with the construction of the Three Gorges Dam are numerous and include soil erosion, resettlement of communities, and far-reaching environmental impacts. One consequence not associated with the dam's construction is increased agricultural productivity; in fact, many farmers were displaced to less fertile areas due to the dam and suffered from poorer soil quality.
The construction of the Three Gorges Dam led to the displacement of over 1.24 million people, the submersion of historic villages and archaeological sites, and the flooding of locales once known for their scenic beauty. The environmental repercussions include concerns over possible earthquakes due to the dam being situated on a fault zone, and extensive loss of wildlife habitats due to the dam-induced flooding.
