Science and technology contributed to over half of the expansion of the United States' economy. Africans, however, representing several of the nations that are suffering from poor financial conditions and hunger say GE crops undermine the nations’ capacities to feed themselves by destroying established diversity, native data and property agricultural systems.
This question seems to relate primarily to problems like the proliferation of genetically modified crops in areas where local farming is prevalent, such that local farmers are pushed out of their lands or are pushed out of their markets by cheaper crops. While this is an issue in some areas, it is largely a policy issue which should be addressed by local government. On the whole, scientific advancement leads to more robust crops, more efficient growing and harvesting methods, and more effective delivery methods to market. Optimistically, one could argue that advancement in the science of solar technology could lead to more sustainable growing operations, as well as could advancement in irrigation technology, or vertical growing operations. Advancements in nutritional science could lead to more efficient feeding of livestock, which could reduce the cost or time-to-market of various meat. There are many different scientific fields that contribute to the agricultural industry worldwide, and in general, advancement in these fields cannot undermine a country's ability to feed itself if it is doing so already (again, local government should regulate what industry is permitted to disrupt current operations that provide people with food). In fact, the easier it is to produce food, the more likely it should be that aid organizations and charities should be able to provide to those areas that cannot currently provide for themselves.
