Many human societies across the world have collapsed or almost gone into extinction because of the scarcity of natural resources. Others however, have survived by either migrating to seek for natural resources elsewhere or by transition and/or adaptation to new environmental conditions. This narrative review paper examines how a society of Machakos District in Kenya has managed to escape from a potential collapse driven... Read more.

Large-scale coal mining practices, particularly surface coal extraction and associated valley fills as well as residential wastewater discharge, are of ecological concern for aquatic systems in central Appalachia. Identifying and quantifying alterations to ecosystems along a gradient of spatial scales is a necessary first-step to aid in mitigation of negative consequences to aquatic biota. In central Appalachian... Read more.

The fate of the forest is usually connected with forest management systems, societal demands as well as exposure to major disturbances such as wildfires, heavy browsing animals. Since the early 1990s, Tanzania have adopted participatory forest management (PFM) approaches, namely Community Based Forest Management (CBFM) and Joint forest management (JFM) to effectively and adequately protect the forests. In Manyara region... Read more.

The importance of phytoplankton in fresh water environment cannot be over emphasized. This study was designed to determine the phytoplankton diversity and abundance in water bodies exposed to different anthropogenic pressures. Water samples were collected from 19 water sources in four categories: Car wash, Municipal wastes, Car wash + Municipal wastes and Drinking water. Phytoplankton species were determined following...

The Tamang community is one of the poor groups living in Middle Mountain of Nepal. It pre-dominantly resides in Buffer Zone of Langtang National Park, located in north-central Nepal. The Buffer zones is areas of settlements and agriculture surrounding the core area set aside for wildlife habitats and rare flora. Access on buffer zone programs depends greatly on their representation on local institutions. There are three... Read more.

Mangrove stands in the Western and Central African countries especially that of Cameroon are declining due to diverse drivers. Actually, Rhizophora racemosa stands in the Cameroon Estuary have been degraded through over-exploitation for fish smoking, pole-wood extraction and fuel wood harvesting by local people in the midst where there is no specific law protecting this ecosystem. Recently, community-based mangrove... Read more.

Human-wildlife conflict (HWC) exists in different forms all over the world and is experienced more in developing countries. The conflict between human and wildlife ranks among the main threats to biodiversity conservation and has become frequent and severe in different parts of Africa. In the author s’ previous study, five species of wildlife were identified as the main crop raiding species in Gera, southwestern... Read more.

Anthropogenic activities have the potential to thwart efforts towards enhancing the full carbon (C) sink potential of savannas in the context of mitigating the effects of global warming. The understanding of the induced effects of human pressures on the carbon budget of forest˗savanna ecosystems is therefore a valuable tool to better evaluate and predict the current and future effects of human activities on the...

Increasing effects of climate change has led to an urgent need for reliable estimates of the soil carbon pool (SOC) which is one of the carbon sinks in the world. This is especially true in Africa where there is lack of basic data. This study conducted in the southern part of Mount Cameroon National Park (MCNP) seeks to determine SOC patterns and estimate CO2 equivalence from SOC pool following land-use changes. Nine...
