Benefits of carbon markets to small and medium enterprises (SMEs) in harvested wood products: A case study from Saharanpur, Uttra Pradesh, India
Harvested wooden handicrafts products have the ability to lock carbon for long time and mitigate climate change. These products are currently eligible for availing benefits from voluntary carbon markets. The market size and opportunities for carbon credits are likely to increase substantially for these products during the post-2012 UNFCCC period. This paper analyses the limitations and opportunities for...

The effect of crude oil on growth of the weed (Paspalum scrobiculatum L.) –phytoremediation potential of the plant
The use of grasses for phytoremediation of crude oil polluted soils especially in the tropics is a new area of study with a lot of potentials. The effect of different levels (0.00, 2.50, 5.00, 7.50, 10.00, 12.50 and 15.00%) of crude oil contamination on the growth of Paspalum scrobiculatum, a common weed in Nigeria was investigated. The weed is found growing luxuriantly in crude oil contaminated...

On farm evaluation of the contribution of three green manures to maize yield in the semi-deciduous forest zone of Ghana
Low soil fertility is one of the major factors responsible for low crop yields on small-scale farms in Africa. The use of Chromolaena odorata, Crotalaria junceaand Panicum maximum and their combination with NPK for improving soil fertility and maize yield was investigated in the semi-deciduous forest zone of Ghana. Each plant material was applied at two application rates, 1 and 3 t ha-1....

Assessment of soil-pollution by slag from an automobile battery manufacturing plant in Nigeria
This study assessed heavy metals pollution of soil by slag from an automobile battery manufacturing plant in Nigeria to ascertain the potential danger they pose on the environment. 84 soil samples were randomly collected at 0 - 15 cm and 15 - 30 cm depths from the premises of the plant and an uncontaminated site as control for both dry and wet seasons. Samples were analyzed for lead, cadmium, chromium and...

Fluoride distribution in different environmental segments at Hirakud Orissa (India)
Fluoride is a major pollutant originating from aluminium smelting polluting the air, water and soil. An Aluminium smelter has been operating at Hirakud in western Orissa since 1958 producing primary aluminium by Horizontal stud Soderberg Technology. Starting with a capacity of 10,000 T of aluminium per annum in 1959 it has increased its capacity to 1,00,000 T in 2007. A detailed investigation undertaken...

Low cost solar dryer for fish
Prawns (Kolambi) were selected as drying material in low cost solar dryer (LCSD). Time required for reducing the moisture content from 75 to 16% were observed in open sun drying and solar drying for its comparison. Salted fish inside the dryer required 8 h in order to dry prawns up to 16.15% while unsalted fish required 15 h to reach moisture content up to 15.15% in open condition. Overall collection...
