Most of the domestic and agro-waste in African cities end up in open dumps and natural water bodies thus causing severe environmental and health problems. These waste streams have resources such as nutrient and energy that can be valorized by transforming them into valuable products.

There is a huge potential for yield increase of agricultural crop residues and biomass from forestry in the European Union, Ukraine, Russia and Belarus.

Centre for Science and Environment (CSE) has released its analysis of air quality data during the second phase of odd and even scheme – from April 15 to April 30. This shows that air pollution took a downward dip during the first 10 days of the scheme but registers a sudden spike from April 22 onwards. Further investigations and analysis of NASA satellite pictures has exposed massive crop fires in Punjab and Haryana that started around April 19 – which could be the reason behind the rise in pollution levels.

Food economy plays a major role in world development. A food chain, from an economic point of view, means a long series of interdependent management processes, which have the main goal to providing food to people.

Substantial potential exists to expand both food and fuel supply in a sustainable fashion.

The Pradhan Mantri Ujjwala Yojana, to provide concessional LPG connections, is a step in the right direction but much more needs to be done by 2019 and beyond to ensure homes in India cook using modern fuels. This article explores the issues of providing connections, subsidy provisioning and ensuring sustained use of LPG and other modern fuels, so as to displace solid fuels from Indian kitchens. It also highlights the need for planning for increased demand and addressing institutional gaps to ensure that the benefits of modern fuel adoption, especially health benefits, are realised.

UNCTAD's first report on the state of biofuel technologies in 2007 highlighted a sector with great potential, but at the time that was a long way off from markets.

In this article we review how different management technologies like integrated nutrient management, tillage practices, mulching, addition of clay, surface compaction, conservation tillage, use of polymers, etc. can favourably modify the soil physical properties like bulk density, porosity, aeration, soil moisture, soil aggregation, water retention and transmission properties, and soil processes like evaporation, infiltration, run-off and soil loss for better crop growth and yield.

Judgement of the National Green Tribunal in the matter of Randhir Singh & Others Vs State of Haryana & Others dated 29/01/2016. The Application was for restraining the M/s Haryana Liquors Pvt. Ltd. from carrying on construction activity for the proposed Grain/Molasses Distillery Unit in its current location in the village Jundla, District Karnal.

Applications stands dismissed.

We use the GLOMAP global aerosol model evaluated against observations of surface particulate matter (PM2.5) and aerosol optical depth (AOD) to better understand the impacts of biomass burning on tropical aerosol. To explore the uncertainty in emissions we use three satellite-derived fire emission datasets (GFED3, GFAS1 and FINN1) in the model, in which tropical fires account for 66–84 % of global particulate emissions from fire. The model underestimates PM2.5 concentrations where observations are available over South America and AOD over South America, Africa and Southeast Asia.
