ROLE OF ROADSIDE PLANTATION ON CLIMATE CHANGE MITIGATION THROUGH CARBON SEQUESTRATION OF DHAKA NORTHERN CITY

Abstract

Diversified vegetation either naturally grown or planted support the ecosystem in which roads are constructed anthropogenicaly and perform an essential role in carbon sequestration as well as climate change mitigation. An importance has been taken by plantation REDD+ strategies as enlarging carbon sequestration. Present study was conducted in 2015 for monitoring plant diversity and their relation to store carbon in both soil and vegetation along the major 9 roadsides of Dhaka northern city. Shannon-Wiener diversity index (SWI) was used for plant diversity measurement. Significant positive association was observed between diversity and richness of plants with both above and below ground biomass. Species richness and diversity of saplings, herbs and shrubs had positive correlation (p˂0.05) with carbon storage in both biomass and soils. In case of Airport road plant diversity, species richness were found top most, whereas in Technical to Shyamoli roadside had negative affect on plant diversity and carbon storage. Intensive plantation in Airport roadside affected carbon storage positively. Conclusively, effectiveness of vegetation, texture, nutrient status, history of the place had significant effect on carbon storage. Therefore, it is an evident that roadside plantation is an essential procedure of carbon sequestration and consequently turning a city to be transformed into more suitable and healthier for living and thus help to mitigate climate change.
