The years 2021 to 2030 have been designated as "The United Nations Decade on Ecosystem Restoration". Ecological restoration and biodiversity conservation efforts face unprecedented challenges, especially in developing countries and areas, such as the Hindu Kush-Himalayan (HKH) region. This huge HKH region, which includes areas in eight separate countries (Afghanistan, Pakistan, Nepal, India, China, Bangladesh, Myanmar and Bhutan), is a biodiversity hotspot with a vast array of ecosystems, ...

Algae are sunlight-driven cell factories, and can efficiently absorb CO2 and convert light energy to chemical energy such as lipid, starch and other carbohydrates and release O2. Algal feedstock is a promising resource for bioproduct production, given its high photosynthetic efficiency for producing biomass compared to conventional crops. Microalgae can be used for flue-gas and wastewater bioremediation. This book highlights recent breakthroughs in the multidisciplinary areas of algal biot...
