“…Phuket Island was more developed and urbanized than the other two islands, of which Koh Yao Noi was more developed than Koh Yao Yai. During the last few years the entire study area has become more developed, with increasing urbanization, agriculture encroaching into terrestrial forest and shrimp farms encroaching on mangrove forests (Hossain et al, 2009).…”

Land Use Effects on Mangrove Nutrient Status in Phang Nga Bay, Thailand

Tropical mangrove forests can play an important role in the functioning of adjacent marine ecosystems, by protecting them from an excess in land-derived sediment and nutrients. The strength of this interaction may however depend on the nutrient status of the mangrove forest.This study related the nutrient status of eight mangrove forests in Phang Nga Bay (Thailand) to 5 the land-cover distributions in the upstream catchment areas. Nutrient status was assessed using indicators integrating over short (porewater and sediment nutrient composition) and long timespans (mangrove leaves and sesarmid crab tissue characteristics). Using multivariate statistics (PCA analysis), these nutrient status data were then related to the land cover data, which were obtained through the analysis of satellite imagery. Nutrient availability was lowest

“…Remote sensing can play a crucial role to map and monitor mangroves and their changes over a period of time. Mangrove mapping has been done using aerial photographs (Manson et al 2001;Hossain et al 2009); satellite remote sensing using Landsat (Vasconcelos et al 2002;James et al 2007;Giri et al 2008;Rahman et al 2013) and SPOT (Vits and Tack 1995;Manson et al 2001;Liu et al 2008;Lee and Yeh 2009) imagery have also been utilized extensively for mangrove forest mapping. In addition to optical remote sensing, Synthetic Aperture Radar (SAR) data has been used for mangrove vegetation studies (Kovacs et al 2013).…”

“…Different image analysis methods have been used for mangrove mapping and change analysis. Visual interpretation (Gang and Agatsiva 1991;Murray et al 2003;Fromard et al 2004), vegetation index (Blasco et al 1986;Jensen et al 1991), unsupervised classification (Vits and Tack 1995;Murray et al 2003;Bhatt et al 2009), supervised classification (Dutrieux et al 1990;Vits and Tack 1995;Aschbacher et al 1995;Giri et al 2007;Thu and Populus 2007), band ratioing (Populus and Lantieri 1991;Long et al 1994;Rahman et al 2013), hybrid classification (Giri et al 2008;Hossain et al 2009), object based classification (Conchedda et al 2008) and other techniques have been used in the mapping of mangroves in different parts of the world.…”

Mangroves are important coastal ecosystems and are located at the inter-tidal zones of tropical and sub-tropical belts. The global mangrove forests are declining dramatically because of the conversion of forests to shrimp farming, over-exploitation, pollution and freshwater diversion. The Bangladesh Forest Department initiated mangrove afforestation throughout the coastal belts of Bangladesh in 1966 to provide better protection for the coastal communities. Up to 1990, 120,000 ha of mangroves had been planted and it is one of the largest coastal afforestaton programs in the world. The objective of this study is to exploit the spatial extent of mangrove plantation and their dynamics of changes over the last two decades using multispectral Landsat imagery. The study area covers the coastal areas of Bangladesh that is extended over the eastern part of Sundarbans up to Teknaf, the southern tip of mainland Bangladesh. Mangrove plantations were interpreted visually on computer screen and interactive delineation of forest boundary was done. The mangrove plantation area has been estimated as 32,725, 47,636 and 43,166 ha for the year of 1989, 2000 and 2010, respectively. Mangrove deforestation by human activity has increased almost six times in the recent decade in comparison to the previous one. The mangrove forest loss due to coastal erosion has slightly declined in the 2000s. Mangroves have been lost primarily because of agricultural expansion. The result of this investigation will be helpful to understand the dynamics of mangrove plantation and the main drivers of changes in this coastal ecosystem.

“…The seven towns vary in area from 64 to almost 1700 ha, with populations ranging from 3600 to more (Hossain et al 2009;Manandhar et al 2010). All images were classified using supervised classification based on forest maps obtained from Jilin Province and the China Jilin Forest Industry Group Co, Ltd. and finalized after classification using ancillary data.…”

Extensive land-use and land-cover change, triggered by rapid development of tourism and the expansion of townships, has occurred in the area surrounding the Changbai Mountain Biosphere Reserve (CMBR) in northeast China, a reservoir for distinctive ecosystems and biological diversity. The objective of this study was to examine the land-use changes surrounding the reserve in the context of forest and nature reserve management with the aid of maps from Landsat MSS imagery of 1977 and Landsat TM imagery of 1991 and 2007. The total land area and its change over time for each land-use class were calculated and cell-by-cell change data were used to detect, quantify, and determine the trends in land-use conversions. Results showed that there were large increases in land area for residential, commercial, industrial, and transportation land-use types, whereas the forest area decreased considerably. At the same time, the area under jurisdiction of townships has nearly doubled, with the largest increase in Manjiang. Land-use change was caused by regional population growth as a result of tourism development that triggered the expansion of township boundaries and contributed to shifts in forest management policy. Our study offers land and reserve managers within the CMBR and similar areas a basis for making more informed land-use and management decisions to potentially minimize detrimental ecological impacts of land-use change.
