Understanding of Cultural Ecosystem Services in Urban Green Spaces: A Case Study in Ramna Park, Dhaka, Bangladesh

Noshin Nawar Jahan, Abdur Rahim Mozomdar, Ummeh Saika, Mohammad Ismail Hossain, Mohammad Nayeem Aziz Ansari
Green spaces provide a variety of ecosystem services. Urban green spaces are particularly valuable because they provide cultural services to urban residents. This study examined people’s opinions of cultural ecosystem services in Ramna Park, Dhaka, Bangladesh. We examined the cultural ecosystem services that green places provide by surveying visitors in the study area about which cultural services they are frequently getting and what their primary activities are in such green areas, to learn how...

Mapping and Botanical Study of Pressures Causing Mangrove Dynamics of Tiko (Southwest Cameroon)

Fulbert Rodrigue Zogning Lontsi, Paul Tchawa, Joseph Pascal Mbaha
This research aims to highlight the effect of human activities and speculative fishing on the dynamic of Tiko mangrove landscapes. The study is based on the collection of bibliographical and factual data (field observations, botanical records) and the diachronic analysis of satellite images of the locality over the past five decades. The NDVI method was used to illustrate the dynamics of land use between 1976, 1986, 1996, 2006 and 2016. Botanical surveys were carried out in three transects 100 m...

Rural Livelihoods and Forest Incomes in the Etinde Community Forest of South West Cameroon

Mukete Beckline, Zhongqiu Sun, Vivian Ntoko, Dominic Ngwesse, Abdul Manan, Yang Hu, Ngoe Mukete, Loveline Che, Jacinta Foncha
For several decades, many households in rural areas have relied on surrounding forests for their livelihoods, safety nets and sustenance. This reliance is most often determined by the household’s characteristics, available forests and economic benefits. That notwithstanding, the demand for more farmlands and unsustainable harvesting of forest resources are pushing these forests into depletion. This rapid decline endangers the livelihoods of forest-reliant households, threatens biodiversity and i...

Natural Regeneration of Indigenous Species under Plantation Forests of Mahoganis (Swietenia macrophylla and Swietenia xaubrevilleana): The Case of Martinique

Philippe Joseph, Kévine Baillard, Jean-Philippe Claude, Yelji Abati, Séverine Ely-Marius, Stéphane Sophie, Yanis Jean-Francois, Jean-Emile Simphor, Peguy Major
In many geographic areas influenced by tropical and temperate climates, natural forest ecosystems have been destroyed in favour of plantations of allochthonous trees which are economically profitable for different aspects of the timber industry. Some of these mature plantations degrade the soils and inhibit natural regeneration of the local flora; others, due to the physical constraints they impose, can contribute to the installation and the development of autochthonous taxa. The plantations of ...

Role of Women in Maintaining Suburban Agricultural Land in Togo (West Africa)

Anissou Bawa, Kouyadega Djalna, Hodabalo Kamou, Komlan Batawila, Jacques Imbernon, Koffi Akpagana
The preservation of suburban agricultural land in the face of rapid urbanization in the West African region has been a major problem in recent decades. This paper examines the land tenure strategies used by farmers in relation to their assessments of the impact of urban growth. It is based on individual surveys conducted among farmers and landowners on the outskirts of the city of Lomé in Togo. This study reveals that perceptions differ according to gender and that women—although marginalized by...

Micronutrient Contents of Heritiera fomes Species at Three Saline Zones of the Sundarban Mangrove Forest, Bangladesh

Hasina Mariam, A. N. M. Alamgir
Micronutrient or essential heavy metals viz. Copper (Cu), Zinc (Zn) and Iron (Fe) distribution trend were studied at the age of 6, 9 and 30 months old Heritiera fomes seedlings at three distinct saline zones viz. Chandpai (Oligohaline), Jungra (Mesohaline) and Munshiganj (Polyhaline) of the Sundarban mangrove forest. Among the observed micronutrients, Fe content comparatively lower than Cu and Zn. Relatively higher Cu was found in the root of 6 month age Heritiera fomes seedlings grown at the Ch...

Assessing the Floristic Biodiversity and Carbon Stock in a Republic of Congo’s Forest Ecosystem

Donatien Nzala, Romeo Ekoungoulou, Bernadin Y. Ngoumba
Reforestation management goes through the knowledge of the tired out evolution after a forestry rest. The aim of this study was to assess biodi-versity concerning Terminalia superba Engl. & Diels and its undergrowth, and then quantify sequestered carbon stocks to appreciate the impact of reforestation on forest recovery and the enhancement of carbon stocks. The study was conducted at Bilala artificial forest in southeastern Re

Classification, Characterization and Comparison of Aquatic Ecosystems in the Landscape of Adilabad District, Telangana, Deccan Region, India

Medagam Thirupathi Reddy, Natarajan Sivaraj, Venkateswaran Kamala, Someswara Rao Pandravada, Neelam Sunil, Nilamani Dikshit
A landscape is a mosaic of natural and/or artificial communities and wa-terbodies and may contain several distinct ecosystems. Human life depends on many services delivered by the water-based aquatic and land-based terrestrial ecosystems. A wide variety of aquatic ecosystems exist and alt-hough they represent a low percentage of the Earth’s surface, their roles and functions make them crucial. Aquatic ecosystems especia

Detection of Horizontal Transfer of Housekeeping and Hydrocarbons Catabolism Genes in Bacterial Genus with Potential to Application in Bioremediation Process

Edmo Montes Rodrigues, Fernanda de Souza Freitas, Tatiane de Paula Siqueira
In silico analysis can be useful to infer about the horizontal gene transfer (HGT) as well as to deduce about the evolutionary relations of catabolic genes. In this study, we performed the analysis of two housekeeping genes (fabD and rpoD) and two catabolic gene
