Biodiversity is critical for sustainability but it being increasingly threatened by anthropogenic activities, such as abitats’ degradation through deforestation, unsustainable shifting cultivation and draining of wetlands; well industrialisation overexploitation flora fauna which includes fishing, excessive consumption fuel wood overharvesting medicinal plants. Human modification the ecosystems...
This study attempts to examine the linkage between environmental degradation and economic growth in Pakistan over the period 1972-2011. The main concern of this study is to test the validity of Environmental Kuznets Curve in case of Pakistan and aims to find out the total and per capita carbon efficiency of Pakistan. Moreover, this study estimates the tipping point of environmental Kuznets curv...
The working paper describes a study which aims to examine and evaluate local community responses to environmental degradation, and factors assisting or hampering local involvement in neighbourhood environmental renewal in two Durham coalfield communities in the UK, an area characterised by high levels of unemployment, poverty, poor health and environmental degradation.

Methyl iodide (MeI) is a promising alternative to the phased-out fumigant methyl bromide (MeBr); however, there are concerns about its environmental fate following soil fumigation. Laboratory experiments were conducted to investigate the effect of various environmental factors on the rate of MeI degradation in soil. The chemical was added to soil at 48.6 mg kg(-1) and incubated under different ...
We investigate the impact on effective terrorism response of the viability degradation of biological weapons agents in the environment. We briefly review the scientific understanding and modeling of agent environmental viability degradation. In general, agent susceptibility to viability loss is greatest for vegetative bacteria, intermediate for viruses, and least for bacterial spores. Survival ...
