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...

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...

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 ...

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 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...

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 ...

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 ...

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 ...

In
Laos, the cultivation of fast growing trees as eucalypts has been promoted due
to a rapid decline in natural forest cover. However, this expansion of fast
growing trees might not end in a win-win situation for both humans and the
environment. This paper examines the social and ecological potentials of Eucalyptus
(Eucalyptus ...
