Abstract
Wetland is crucial in supporting biodiversity conservation and climate change regulation. A wetland ecosystem has been influenced by anthropogenic driven climate change. The main objective of this paper is to analyze the role of wetlands for climate change mitigation and biodiversity conservation through literature review. Wetland is vulnerable to climate change through alterations of hydrological regimes that lead to changes in quantity and quality of water. Climate change is undoubtedly the most pervasive, complex and challenging of the global environmental issues facing contemporary society and it affects all aspects of development. Wetlands play a key role in hydrological and biogeochemical cycles, and provide a wide range of ecosystem goods and services to humankind. In spite of these facts, wetlands are considered as wastelands in the past, which contributes for deterioration of wetlands in several places. Thus, strong environmental policy is required for the conservation of wetland ecosystem.Keywords: carbon sequestration, climate change, climate change mitigation, biodiversity conservation, wetlands

Wetlands play a key role in hydrological and biogeochemical cycles, and provide a wide range of ecosystem goods and services to humankind
Wetlands and Climate Change: Wetlands are among the most important natural resources on earth that provide a potential sink for atmospheric carbon but-if not managed properly, they become a source of greenhouse gases (Adhikari et al, 2009)
It is sound to work on wetland restoration management, which is an important tool for stakeholders and practitioners to mitigate climate change and maintain ecological functioning (Dorau et al, 2015)
Summary
Wetlands play a key role in hydrological and biogeochemical cycles, and provide a wide range of ecosystem goods and services to humankind. Sediment condition differences and human activities like agricultural practices, built up and deforestation are the major causes of wetland deterioration (Orimoloye et al, 2018). Wetland ecosystems are under threats due to change in water regimes as a result of river regulation and climate change (Fu et al, 2015). Global climate change is recognized as one of the key drivers of degradation of wetland ecosystems, causing considerable change of services provided by these habitats (Mehvar et al, 2019). This study is aimed to review the role of wetlands for climate change mitigation and its potential in biodiversity conservation
