Desertification is a process that occurs in arid and semi-arid regions, and is not directly related to climate change in coastal zones.

The melting of glaciers and ice sheets, particularly in Greenland and Antarctica, is the primary contributor to sea-level rise.

Hard engineering approaches involve the construction of physical structures, such as seawalls, levees, and storm surge barriers, to protect coastal areas from flooding and erosion.

Managed retreat involves the planned and orderly relocation of people and infrastructure away from areas that are at risk from climate change impacts, such as sea-level rise and coastal flooding.

Nature-based solutions utilize natural ecosystems to provide protection against coastal hazards. Mangroves, for example, can help to reduce erosion and storm surge impacts by acting as a natural buffer.

Adaptation refers to the actions taken to reduce the vulnerability of human and natural systems to the impacts of climate change, without necessarily reducing greenhouse gas emissions.

While important, cultural heritage preservation is not typically a primary consideration in developing adaptation strategies for coastal zones, which focus on protecting human lives, property, and infrastructure.

Resilience refers to the capacity of a system to withstand and recover from the impacts of climate change, including extreme weather events and sea-level rise.

Sea-level rise is generally associated with negative impacts on coastal zones, including increased flooding, salinization of freshwater resources, and loss of coastal ecosystems. Increased agricultural productivity is not a typical consequence of sea-level rise.

Mitigation refers to actions taken to reduce greenhouse gas emissions and slow the pace of climate change.

Increasing agricultural production is not a typical adaptation strategy for coastal communities facing sea-level rise, as rising sea levels can lead to salinization of freshwater resources and loss of agricultural land.

Vulnerability assessment involves evaluating the exposure, sensitivity, and adaptive capacity of a coastal system to climate change impacts, in order to identify areas and populations that are most at risk.

Technical limitations are not typically a major challenge in implementing adaptation strategies in coastal zones, as there is a wealth of knowledge and experience available on coastal engineering and management practices.

Adaptation planning involves incorporating climate change adaptation considerations into coastal planning and management processes, to ensure that coastal communities are prepared for the impacts of climate change.

Implementing adaptation strategies in coastal zones is generally expected to reduce vulnerability and enhance resilience to climate change impacts, rather than increasing vulnerability.
