The impacts of climate change affect the increase in temperature and the decrease in precipitation levels, which may be reflected in agricultural productivity, compromising, in a certain way, the income of this economic sector. It is in this context that we set out to reflect how climate change has affected agriculture in Niassa province, with the aim of analyzing the impact of climate change on agriculture. Specifically characterize the change in temperature and precipitation; explain how such change can influence crop degradation and present crop alternatives resilient to climate change and other alternatives that guarantee the development of the agrarian sector. The interview, the analysis of thernnopluvionnetric data, documentary study and the bibliographic review, are elements that supported to carry out the research. The change in climatic patterns, mainly the increase in temperature and the decrease or increase in precipitation, affect the agricultural sector, with a greater focus on crop degradation. The use of adaptive crops that are resilient to climate change, associated with new technologies, becomes an alternative to ensure the balance of production levels and ensure food security.
