In other situations, adaptation limits to household livelihoods emerge from ecological thresholds associated with global warming temper- atures, such as deterioration of land and water resources, extinction of species and biodiversity that can lead to systemic crop failures, declin- ing fisheries productivity and water availability and substantial risks to households' livelihoods . However, it is also important to note that limits are associated with development, technology and cultural norms and values that can change over time to enhance or reduce the capacity of systems to avoid limits . It could also include aspects of maintaining security of air or water quality, as well as equity, cultural cohesion and preser- vation of livelihoods .
