Drought is a complex phenomenon − relating to the absence of water − which is difficult to monitor and define. [18] By the early 1980s, over 150 definitions of "drought" had already been published. [19] The range of definitions reflects differences in regions, needs, and disciplinary approaches.
Climate resilience is generally considered to be the ability to recover from, or to mitigate vulnerability to, climate-related shocks such as floods and droughts. [7] It is a political process that strengthens the ability of all to mitigate vulnerability to risks from, and adapt to changing patterns in, climate hazards and variability.
In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and subsequently recovering. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil ...
The IPCC considers climate resilience to be “the capacity of social, economic and ecosystems to cope with a hazardous event or trend or disturbance”. It includes the abilities to reorganise and learn. [9]: 7 This definition is similar to that of climate change adaptation. However, resilience involves a more systematic approach to absorbing ...
The U.S. Drought Monitor provides a national database to track the duration and severity of droughts in the United States. It is hosted by the University of Nebraska-Lincoln with assistance from the United States Department of Agriculture and the National Oceanic and Atmospheric Administration.
A natural disaster is the highly harmful impact on a society or community following a natural hazard event. The term "disaster" itself is defined as follows: "Disasters are serious disruptions to the functioning of a community that exceed its capacity to cope using its own resources.
A local farmer in Myanmar poses in front of a mango field that is a part of a Climate Smart Village.. Climate-smart agriculture (CSA) (or climate resilient agriculture) is a set of farming methods that has three main objectives with regards to climate change.
Academic discussion of urban resilience has focused primarily on three threats: climate change, natural disasters, and terrorism. [7] [8] Accordingly, resilience strategies have tended to be conceived of in terms of counter-terrorism, other disasters (earthquakes, wildfires, tsunamis, coastal flooding, solar flares, etc.), and infrastructure adoption of sustainable energy.
