Mangroves stand out as one of the most diverse and biologically significant natural systems in the world. Playing critical roles in maintaining the health and productivity of coastal ecosystems, mangroves provide a range of services and functions, including habitat for local fauna and flora, food and other goods, carbon sequestration, and protection from natural disasters such as storm surges and coastal erosion. It is also evident that mangroves face several threats, which have already led to the gradual depletion of mangrove areas worldwide. Based on the analysis of current and related historical literature and data, this review summarises mangrove functions and the threats and challenges associated with mangrove management practices. Our findings suggest that coastal development, expanded aquaculture, deforestation, climate change, and other associated implications such as eutrophication, diseases, and pollution are the major factors posing threats to mangrove sustainability. We also highlight the various challenges, such as land use conflict, a lack of stringent regulatory actions, inadequate policy and government frameworks, and a lack of community awareness, that underlie ineffective mangrove management. The implementation of inclusive and coordinated approaches involving stakeholders from different backgrounds and interests, governmental and non-governmental organisations, and academia is essential for mangrove restoration and sustainable mangrove management by adapting mitigation strategies.

Fusarium is the most common soil-borne pathogen that causes wilt in many plant crops, among which the tomato is one of the most susceptible crops. This experiment is conducted to analyse the impacts of inorganic carbon compounds i.e., calcium carbonate CaCO3, sodium carbonate Na2CO3 and potassium bicarbonate KHCO3 on the growth of Fusarium oxysporum f. sp. lycopersici (FOL) causing wilt in tomato plant in different culture media including Malt Extract Agar (MEA), Potato Dextrose Agar (PDA) and V8. Three concentrations viz 0.5 g/L, 1 g/L and 1.5 g/L of each carbonate are applied. The study indicates that the efficiency of carbon compounds is related to the nature of the media. Among various carbon compounds tested in the present study, maximum growth is obtained with KHCO3 while FOL showed least growth with Na2CO3 in each of the three media. MEA has more profound effect on limiting the growth and biomass of the fungus than compared to V8 and PDA. This shows Fusarium growth is restricted in the chemical environment containing Na2CO3 and MEA. In addition, the study reflects that Fusarium thrives well in PDA containing KHCO3 in each of its three concentrations which may be involved in vegetative and reproductive growth. This study paves a path for further research on how the growth behavior of FOL can be controlled under the influence of inorganic carbon compounds in the soil and yet in the face of environmental changes.
