1. Calcareous Algae of a Tropical Lagoon : Primary Productivity, Calcification and Carbonate Production
Abstract : The green algae of the genus Halimeda Lamouroux (Chlorophyta, Bryopsidales) and the encrusting loose-lying red coralline algae (Rhodophyta, Corallinales) known as rhodoliths are abundant and widespread in all oceans. They significantly contribute to primary productivity while alive and production of CaCO3 rich sediment materials on death and decay. READ MORE

2. In the wake of the Green Revolution : Environmental and socioeconomic consequences of intensive rice agriculture - The Problems of weeds in Muda, Malaysia
Abstract : The agricultural intensification strategies represented by the Green Revolution have since the mid-1960s had a very positive impact on food-grain production in Asia. Presently, however, a post-Green Revolution phase of declining growth in output and productivity is experienced in many of the areas where intensification took place. READ MORE

3. Strategic nitrogen management in stockless organic cropping systems : redistribution of residual biomass for improved energy and nitrogen balance
Abstract : A griculture faces the challenge of producing high yields to feed a growing world population, while simultaneously addressing environmental problems such as eutrophication, emissions of greenhouse gases, loss of biodiversity and soil degradation. Organic farming can be part of the solution, as it promotes biodiversity, uses less energy for fertiliser production and often has higher inputs of organic matter to soil than conventional farming.

5. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology
Abstract : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. READ MORE
