Impacts on rural livelihoods and food security, particularly for small and medium-sized farmers and Indigenous peoples in the mountains, are projected to worsen, including the overall reduction of agricultural production, suitable farming area and water availability . Projected yield reductions by 2050 under the A2 scenario are as follows: beans 19%, maize 4-21%, rice 23% in CA with seasonal droughts projected to lengthen, intensify and increase in frequency. Small fisheries and farming of seafood will be negatively affected as El Niño Southern Oscillation  events become more frequent and intense and ocean warming and acidification continues .
