Global climate change is one of the burning issues of present time where carbon has an important role to play. There is growing local to international concern over the increase of carbon in the form of carbon dioxide (CO2) in the atmosphere over the last decades. Organic carbon sequestration trapping by plants is thought to be a promising means for reducing atmospheric CO2, an important green house gas. Bangladesh is now facing and will be very adversely affected due to the adverse affect of global climate change. The Intergovernmental Panel on Climate Change (IPCC) concluded in a 2001 report that, by 2100, average global surface temperature will raise 1.40C to 5.80C above 1990 levels. Increase in temperature is a major concern for future when anybody considers climate change.

Research Objectives and Focus
The primary research objective is to assess the sensitivity of germination, early-stage growth, and organic carbon storage in three indigenous tree species—Albizia procera, Cassia fistula, and Lagerstroemia speciosa—under various temperature scenarios predicted by the IPCC, in order to identify species suitable for future climate conditions.
- Testing seed germination performance across existing, mid-range, and high-temperature scenarios.
- Evaluating initial growth rates and morphological development under varying thermal conditions.
- Quantifying the organic carbon sequestration potential of seedlings during their early developmental stages.
- Evaluating the long-term regeneration viability of forest species essential for local livelihoods and government afforestation efforts.
Excerpt from the Book
Methodology
The study area includes Padua natural forest, the nursery and seed propagation laboratory of Institute of Forestry and Environmental Sciences, Chittagong University. Naturally regenerating species in Padua natural forest are Garjan, Jarul, Silkoroi, Sonalu, Bahera, Amloki, Gutguttya and Hargeza. From these, species will be Jarul (Lagerstroemia speciosa), Silkoroi (Albizia procera) and Sonalu (Cassia fistula) to find out the effect of temperature on those species. I shall be set the experiment in seed propagation laboratory; daily temperature and humidity will be recorded using digital thermometer and hygrometer during the experiment. Seeds of Albizia procera, Cassia fistula will be treated in hot water and will be sown in seed bed. Seedlings will be kept in different temperatures like high, medium, normal and also in open air. Shoot length, leaf length of all seedlings in each treatment will be recorded at every three days interval and will be continued up to month for growth performance study. Daily germination rate will be computed by dividing cumulative germination percentage by the number of days since the beginning of test. To determine seedling organic carbon first these will be grinded the oven dried plant samples then less than 1gm amount of samples will be taken into pre weight crucibles. After adjustment of the furnace at 5500C, ignition will be continued for 1 hour and then ash will be weighted and percentage of ash will be calculated.

Frequently Asked Questions
What is the primary focus of this research?
The research examines the impact of rising global temperatures on the germination, early growth, and carbon sequestration capabilities of three specific indigenous tree species in Bangladesh.
Which tree species are being investigated?
The study focuses on Albizia procera (Silkoroi), Cassia fistula (Sonalu), and Lagerstroemia speciosa (Jarul).
What is the main objective of the study?
The objective is to identify climate-resilient tree species that can maintain regeneration in natural forests despite predicted increases in surface temperatures.
Which scientific method is applied here?
The study utilizes a controlled experimental approach in a seed propagation laboratory, applying various temperature treatments to seedlings and calculating growth performance and carbon mass via incineration.
Why is this research important for local communities?
Local communities rely on these tree species for fuel, timber, and traditional medicine; their potential loss due to climate change would threaten these critical resources.
What climate scenarios does the researcher consider?
The study uses existing, mid-range, and high-temperature scenarios specifically prescribed for the Bangladesh region by the IPCC.
How is the seedling organic carbon determined?
The researchers use oven-dried plant samples which are ground and ignited in a furnace at 550°C to calculate the percentage of ash and subsequent carbon content.
What happens if the tested species fail to germinate?
If germination fails due to climate change, it would result in the loss of government investments in reforestation and jeopardize the availability of multipurpose trees for the local population.
