Phytoplankton in freshwater ponds play a significant yet often underappreciated role in the global carbon cycle, particularly in the context of carbon sequestration and the reduction of atmosphericCO2 levels. These microscopic organisms, primarily algae, perform photosynthesis, a process in which they absorb CO2 from the atmosphere and convert it i...

Mangroves are known for several ecosystem services of which carbon sequestration under the regulating service has gained momentum in recent years. This study aims to evaluate the carbon credit (in INR) from four mangrove patches at Kakdwip and Chemaguri in the western Indian Sundarbans, and Bali Island and Jharkhali in the central Indian Sundarbans...

The present study examines the effects of varying protein levels in fish feed on the condition index of black molly (Poecilia sphenops), a common ornamental fish, over a two-year period (2022 and 2023). Using 25%, 30%, and 35% protein levels, the results revealed that higher protein content led to greater growth in length and weight, with the 35% p...

The Lower Gangetic Delta, encompassing the mangrove dominated Sundarban region, is one of the world's largest river deltas, formed by the Ganges, Brahmaputra, and Meghna rivers. Spanning 9,630 km² across the Indian part, it houses the Indian Sundarban Biosphere Reserve. This reserve, divided into western, central, and eastern sectors, experiences v...

This study demonstrates the potential of machine learning to revolutionize carp aquaculture by providing accurate and efficient growth assessments. The study was undertaken at Sirakol in the South 24 Parganas district of West Bengal during 2021 using Gibelion catla as the candidate carp species fed with probiotics-based feed. Among the four ponds,...

We present evidence that the Indian Sundarbans is experiencing the effects of climate change over the last three decades. Observations of selected variables, such as the surface water temperature, salinity, pH, dissolved oxygen, and transparency show significant long-term variation over a period of 27 years (1980-2007). Specifically, the temperatur...

This book delves into the rich biodiversity and ecological significance of the Sundarbans mangroves, focusing on their exceptional carbon sequestration abilities. It explores innovative carbon trading mechanisms, emphasizing their potential for environmental and economic sustainability. Highlighting challenges like salinity changes, data gaps, and...

Eutrophication has become a critical environmental issue worldwide, primarily driven by elevated nutrient levels in aquatic ecosystems. Excessive nitrogen (N) and phosphorus (P) from domestic waste, tourism, agriculture, and aquaculture intensify this process in coastal and estuarine environments. In the Lower Gangetic Delta (LGD), nutrient runoff...

The Lodha people reside in the Indian Sundarban islands. They are mainly engaged in fishing activities. They live very close to the river embankments and their major occupation orients around fishery-related livelihoods like deep sea fishing, fish drying, fish feed preparation, etc. Despite spending maximum hours in saline water and extreme humid e...

Mangrove forests provide a wide range of provisioning services like timber, fodder, honey, wax, tannin, fishes etc. and a wide range of environmental services like erosion control, protection from the natural disasters, bioremediation, biodiversity conservation, carbon sequestration etc. The ecosystem contains much larger quantum of stored carbon c...

Environmental factors significantly influence the spread of various infectious diseases, particularly those carried by vectors, such as malaria and dengue. There is substantial evidence highlighting the impact of environmental variables on the transmission and proliferation of malaria and dengue worldwide. Against this backdrop, the current study a...

Impact of fall on carbon sequestration.pdf The color change in maple leaves during fall is primarily due to the breakdown of chlorophyll, the pigment responsible for the green color and essential for photosynthesis. As temperatures cool and daylight hours shorten, chlorophyll production slows down, allowing other pigments like carotenoids (which pr...

We conducted a study during August 2012 and 2017 at Prentice island of Indian Sundarbans to estimate the rate of stored carbon (carbon sequestration) in the mangrove vegetation of the island. On the basis of criterion prescribed for carbon sequestration study (DBH ≥ 5 cm), only 23 species were selected for the estimation. We focused on the stem bio...

The alterations in the salinity profile are an indirect, but potentially sensitive, indicator for detecting changes in precipitation, evaporation, river runoff , glacier retreat, and ice melt. These changes have a high impact on the growth of coastal plant species, such as mangroves. Here, we present estimates of the variability of salinity and the...

This study was undertaken in February, 2021 to determine the role played by the forest cover in lowering the level of carbon dioxide in the atmosphere within the premises of an educational institute in Barasat, North 24 Parganas district, West Bengal (India). Twenty-two dominant tree species from the eight sampling sites were surveyed, out of which...

The mangrove dominated Indian Sundarbans are rich bed for several species of gastropods. These gastropods are the store house of carbon as evidenced from the concentrations of total carbon (% dry weight) in their soft tissues and shells. The present study reveals significant spatial differences of stored carbon in selected gastropod species in Indi...

Sustainable Development Goals (SDGs) are a set of 17 global goals adopted by all United Nations member states in 2015 as part of the 2030 Agenda for Sustainable Development. They aim to address major global challenges, including poverty, inequality, climate change, environmental degradation, peace, and justice. The SDGs are interconnected, meaning...

Industrial activities are a significant source of solid waste, which poses a challenge for environmental sustainability and public health. As industries expand in response to global demands, the volume and complexity of waste produced also increase. Managing this waste effectively is crucial to prevent environmental degradation and promote a circul...

The Indian Sundarbans delta is vulnerable to climate change related effects owing to its location below the mean sea level and experiencing a sea level rise of 3.14 mm/yr. Hence the study is relevant from the point of adaptation of the species to sea level rise and subsequent saline water intrusion into the islands of Indian Sundarbans. Salinity of...
