Recent crop harvesting practices use mechanical harvesters in the rice and wheat farm system in India. These practices leave behind large quantities of crop residue in the field. However, there is no suitable method available for managing the crop residues. Crop residues / biomass burning are cheap and easiest method to dispose the leftover crop residues (wheat, rice, sugarcane etc.) after harvesting, for land clearing and pest control. Burning of crop residues is a common approach to eliminate waste after harvesting all over the world.

Off-grid biomass plants light up villages; experts demand clarity on tariff regulation

Flooded rice fields are an important source of the greenhouse gas CH4. Possible carbon sources for CH4 and CO2 production in rice fields are soil organic matter (SOM), root organic carbon (ROC) and rice straw (RS), but partitioning of the flux between the different carbon sources is difficult. We conducted greenhouse experiments using soil microcosms planted with rice.

Biomass power sector is in trouble. About 60 per cent of the country’s grid-connected power plants that run on biomass are either closed or about to be closed. Reason: rising fuel price, unrevised tariff and government apathy.

Conservation agriculture (CA) is an agricultural management practice in which there is minimum soil disturbance, retention of residue for soil cover and rotation of major crops. In contrast, soil in traditional agriculture is intensively tilled to prepare a fine and well-pulverized seedbed. Soil tillage or land preparation is the most energy-consuming operation among all field operations. Compared to traditional agriculture, farmers can save up to 40% of time, labour and fuels in CA.

Biomass-based power project developers have been facing challenges such as increasing raw material costs, low tariffs, inadequate power evacuation infrastructure etc. While the developers have sought tariff revisions, the issues related to evacuation facilities has not been on the priority list of state governments.

Black carbon (BC) emissions from China are of global concern. A new BC emission inventory (PKU-BC(China)) has been developed with the following improvements: (1) The emission factor database was updated; (2) a 0.1° × 0.1° gridded map was produced for 2007 based on county-level proxies; (3) time trends were derived for 1949–2007 and predicted for 2008–2050; and (4) the uncertainties associated with the inventory were quantified. It was estimated that 1957 Gg of BC were emitted in China in 2007, which is greater than previously reported.

This paper applies an econometric analysis to estimate the average and distribution benefits of rural electrification using rich household survey data from India. The results support that rural electrification helps to reduce time allocated to fuelwood collection by household members and increases time allocated to studying by boys and girls.
