    The Rohingya refugee influx to Bangladesh in 2017 was a historical incident; the number of refugees was so massive that significant impacts to local communities was inevitable. The Bangladesh government provided land in a preserved area for constructing makeshift camps for the refugees. Previous studies have revealed the land cover changes and impacts of the refugee influx around campsites, especially with regard to local forest resources. Our aim is to establish a convenient approach of providing up-to-date information to monitor holistic local situations. We employed a classic unsupervised technique—a combination of k-means clustering and maximum likelihood estimation—with the latest rich time-series satellite images of Sentinal-1 and Sentinal-2. A combination of VV and normalized difference water index (NDWI) images was successful in identifying built-up/disturbed areas, and a combination of VH and NDWI images was successful in differentiating wetland/saltpan, agriculture /open field, degraded forest/bush, and forest areas. By doing this, we provided annual land cover classification maps for the entire Teknaf peninsula for the pre- and post-influx periods with both fair quality and without prior training data. Our analyses revealed that on-going impacts were still observed by May 2021. As a simple estimation of the intervention consequence, the built-up/disturbed areas increased 6825 ha (compared with the 2015–17 period). However, while the impacts on the original forest were not found to be significant, the degraded forest/bush areas were largely degraded by 4606 ha. These cultivated lands would be used for agricultural activities. This is in line with the reported farmers’ increased income, despite local people with other occupations that are all equally facing the decreases in income. The convenience of our unsupervised classification approach would help keep accumulating a time-series land cover classification, which is important in monitoring impacts on local communities.

    The refugee influx from Myanmar, known as Rohingya refugees, is a serious concern for global refugee issues. Bangladesh currently hosts one million Rohingya refugees in the coastal district of Cox’s Bazar. Considering the number of the refugees, in addition to the humanitarian concerns, they are also creating pressure on the local host communities. This study explored the socioeconomic changes of the host communities after the refugee influx. In order to fulfill this study’s objectives, 35 villages near the Rohingya refugee camps from the coastal district of Bangladesh were surveyed. In the villages, 10% of households were surveyed in 2016 and also in 2020, covering 1924 and 2265 households, respectively. A temporal comparison of the host community’s socioeconomic status between 2016 and 2020 was conducted in order to determine the changes after the recent refugee influx. This study found that the local community’s socioeconomic status degraded. The annual income decreased by 24%, which is unusual for a country with over 6% gross domestic product (GDP) growth in recent times. The income decreased from all livelihood options except farming, which could be related to the availability of cheap labor and the high demand for commodities. The villages were clustered using k-means, and 20 villages were found to be affected after the refugee influx with degraded socioeconomic status. The host community’s general perception was initially positive, but later turned negative toward the refugees. This study will be important for the government and donor agencies to develop strategies to properly manage the refugee camps and adjacent host communities.

    © 2018, SPSD Press. Sustainable development requires better understanding of the human-landscape relationship in forested landscapes, one that facilitates more locally relevant and sustainable management. It can be more easily understood by the process of landscape characterisation and humans' valuation. Therefore, this study assesses local people's preferences and perceptions about the physical landscape, which is crucial for managing landscape and livelihood. The study investigates the diversification of landscape character types and landscape character areas (LCA), local people's perceptions about and preferences for different LCAs, and how and why they prefer some LCAs to others. An LCA is a distinct type of landscape that is relatively homogenous in character. Two different villages located in Teknaf peninsula, Bangladesh, are examined where the villages were selected by calculating vegetation cover within a buffer of 1 kilometre. Landform and vegetation data were collected as physical characteristics of the landscape to identify the LCA, and data for local people's perception and preferences were collected through focus group discussions and questionnaire surveys by selecting 10% of the households of each village in March 2016. The findings show that in Kerantali the diversification of landscape character types was more than in Tulatali. Homestead garden areas are highly preferred in Tulatali and forest is highly preferred in Kerantali. Kerantali's people receive poor material benefit from forest areas, whereas Tulatoli's people receive more material benefit from homestead garden areas. Furthermore, our findings indicate that homestead gardens play an important role as a supplement to forests.

    The Teknaf peninsula, which is located in the farthest southeastern corner of Bangladesh, has a diversified physiography exhibiting hills, piedmont plains, tidal floodplains, and beaches. The climate is subtropical, with temperatures ranging seasonally from 15 °C during the winter to 33 °C during the summer and very heavy rainfall (about 4000 mm). The peninsula, which experiences frequent cyclones, is vulnerable to climate change. More than 30% of the area consists of forests that are highly degraded as a result of various human activities as well as climate change such as frequent cyclone. Poverty is one of the major issues in the peninsula, with approximately 38% of the population living below the poverty line. Livelihoods center on agriculture, forest-related activities, and collection of marine resources. Although human settlements have existed in this area from ancient times, after 1990, extensive settlement has occurred in and around the forests. Apart from Bengalis, other ethnic groups living in the peninsula include the Chakma, Rakhine, and Rohingya groups.

    A homestead is an integrated production system where trees, crops, livestock and poultry are found in and around the household residence in Bangladesh. It is a potential production unit that provides various product, service and ecological functions. Almost all people in Bangladesh including landless households have homesteads in which they grow trees and crops even in a small piece of land. This study characterizes the species composition, diversity and productivity of the homestead production system in the Teknaf peninsula, southeastern Bangladesh. Survey data collection was from a total of 180 homesteads covering five household categories: large, medium, small, marginal and landless. Vegetable, fruit, timber, and livestock and poultry were common components in the homestead production system. Various types of plants were mainly concentrated in back yards, front yards, boundaries and corners of homesteads. The mean number of tree species per homestead was about 15. In total, 189 tree and shrub species were recorded, and were distinctly high and low in the large (363.7) and landless (55.7) household categories. Species composition, diversity and productivity of homesteads were found to be related to household categories. Richness and diversity of tree and shrub species increased with household size. Betel nut was the dominant tree species followed by mango, jackfruit and coconut. Annual income from homesteads also varied among the household categories, with a mean contribution of the homestead to annual income of about 25 %. A large portion of homestead income came from betel nut trees. There is scope to increase species diversity and income by designing homesteads with the engagement of women and other family members.
