Adaptation responses that focus on improving incomes through production intensification can have maladaptive outcomes. An oft- cited example of this is groundwater overuse as a result of irrigation intensification. There is widespread evidence of groundwater overuse in many countries in Africa , in the Middle East and North Africa , in Asia , in Spain  and in Australia  . Intensification-based approaches also increase costs of cultivation , and can lead to more use of fertilisers and herbicides . Diversification away from food crops can also compromise domestic food security .
