Innovation can be simply defined as a "new idea, creative thoughts, new imaginations in form of device or method". However, innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs. Such innovation takes place through the provision of more-effective products, processes, services, technologies, or business models that are made available to markets, governments and society. The term "innovation" can be defined as something original and more effective and, as a consequence, new, that "breaks into" the market or society. Innovations tend to be produced by outsiders and founders in startups, rather than existing organizations. Innovation is related to, but not the same as, invention, as innovation is more apt to involve the practical implementation of an invention (i.e. new/improved ability) to make a meaningful impact in the market or society, and not all innovations require an invention.

Answer:
Conflicts with other tribes.
Explanation:
When Settlers traded with one tribe only, the gain in prosperity that is obtained by leveraging on the local resources will only be felt by that one tribes.
The other tribes felt the deteriorating resources (since they live within the same region), but do not receive the same benefit in return as that one tribes. As a result, this will gradually build up resentment towards that one tribes or the European settlers. This what might lead to wars/conflicts.

The question most probably alludes to the Indus River Valley Civilization which is one of the oldest civilizations to ever exist in the human world.
They had quite a high population for the time and so came up with various technological advances to cater for their people including sewage and water systems.
It was their work with irrigation that earned them high praise however. They came up with advanced irrigation techniques which ensured that agriculture boomed and created enough food to feed the population.
