“…The natural vegetation cover (forest, scrub and grassland) is around 29.36% of the total geographical area of India (Reddy et al 2015). The total forest area facing disturbances due to fire is estimated as 57,127.75 km 2 in natural vegetation types.…”

“…The total forest area facing disturbances due to fire is estimated as 57,127.75 km 2 in natural vegetation types. Area of 46.63% in dry deciduous forest types and 32.77% in moist deciduous forest types is burnt by fire every year (Reddy et al 2015). CO 2 emissions from natural grass lands have been identified as an environmental issue in the context of global warming.…”

Effect of fire on nature, biomass, CO 2 flux and carbon sequestration potential of under storey grasses in chir pine forests receiving fire after regular intervals along the altitude and aspect was studied. Species composition, biomass, and productivity patterns of perennial grass communities under Chir-pine dominated forests at different altitudes varied greatly with the level of exploitation and fire incidence. The carbon sequestration by the ground floor species also vary with altitude and fire level. The four types of grass species were found in the fire affected forests viz. Chrysopogon montanus Trin, Apluda mutica, Heteropogon contortus and Themeda anathera. Pure grass land recorded the maximum CO 2 mitigation 16.29 mega grams and the CO 2 mitigation increased with the altitude at same aspect. Similarly, CO 2 mitigation increased from 19.29 to 28.22 mega grams per ha in the soil at different altitude. Forest soils carbon increased from 0.94 % just after the fire and (Zero year after fire) and highest after four years of fire i.e. 1.91 %. The total organic carbon increased up to 41.29 mg ha -1 in forest after four years of fire.

“…5.3.4. WI WI is highly industrialized, with a landscape mainly composed of arable land along with tropical wet and semievergreen forests along the coast (Reddy et al, 2015;Roy et al, 2015). Biomass burning rates in the state of Maharashtra rank among the highest in India (Sahu & Saxena, 2015) and are mainly associated with crop residue burning (~90%; Venkataraman et al, 2006).…”

“…The CI region includes extensive forest, scrubland, and cropland (mainly rice; Roy et al, 2015), along with an industrial/mining belt in West Bengal and Odisha (Guttikunda & Jawahar, 2014). The southwest monsoon provides most of the annual rainfall (60-65%; IMD, 2009;Reddy et al, 2015). Crop residue burning and forest fires are widespread over CI (Figure 2), especially in Chhattisgarh, with forest fires peaking in March (Sahu & Saxena, 2015;Venkataraman et al, 2006).…”

Constraining Emissions of Volatile Organic Compounds Over the Indian Subcontinent Using Space‐Based Formaldehyde Measurements

India is an air pollution mortality hot spot, but regional emissions are poorly understood. We present a high‐resolution nested chemical transport model (GEOS‐Chem) simulation for the Indian subcontinent and use it to interpret formaldehyde (HCHO) observations from two satellite sensors (OMI and GOME‐2A) in terms of constraints on regional volatile organic compound (VOC) emissions. We find modeled biogenic VOC emissions to be overestimated by ~30–60% for most locations and seasons, and derive a best estimate biogenic flux of 16 Tg C/year subcontinent‐wide for year 2009. Terrestrial vegetation provides approximately half the total VOC flux in our base‐case inversions (full uncertainty range: 44–65%). This differs from prior understanding, in which biogenic emissions represent >70% of the total. Our derived anthropogenic VOC emissions increase slightly (13–16% in the base case, for a subcontinent total of 15 Tg C/year in 2009) over RETRO year 2000 values, with some larger regional discrepancies. The optimized anthropogenic emissions agree well with the more recent CEDS inventory, both subcontinent‐wide (within 2%) and regionally. An exception is the Indo‐Gangetic Plain, where we find an underestimate for both RETRO and CEDS. Anthropogenic emissions thus constitute 37–50% of the annual regional VOC source in our base‐case inversions and exceed biogenic emissions over the Indo‐Gangetic Plain, West India, and South India, and over the entire subcontinent during winter and post‐monsoon. Fires are a minor fraction (<7%) of the total regional VOC source in the prior and optimized model. However, evidence suggests that VOC emissions in the fire inventory used here (GFEDv4) are too low over the Indian subcontinent.

“…Identified by Reddy et al (2015) as the Northeast Biogeographic Zone, the region is administratively defined by the Ministry of Development of the northeastern Region (DoNER -http://mdoner.gov.in/) as the states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, and Tripura. It is both one of the world's globally significant centers of biodiversity and a region that is facing a broad range of environmental threats to its future sustainability (Chatterjee et al 2006;Chatterjee 2008).…”

Taxonomic and biological information is reviewed for the forest Hepialidae of northeastern India, a poorly known group of moths in a region known for the global significance of its biodiversity. The taxonomic and biological characteristics are described for genera known from the northeast - Endoclita, Palpifer, and Hepialiscus. A key is provided for distinguishing these genera and the genus Thitarodes known from nearby Bhutan, China, and Nepal, which is almost certainly present within the borders of India. Taxonomic characteristics are described for 12 species from the northeast along with illustrations of the species and maps of their known distributions. Information on species distributions is extremely fragmentary and it is considered very likely that most species have more extensive distributions than currently documented. The northeastern Indian region represents a center of hepialid diversity comprising three principal distribution patterns: (i) local endemics, (ii) Himalayan, and (iii) northeastern. Comparison of distribution records and major vegetation types indicate the absence of information on the hepialid fauna for much of the northeast region. The principal challenge for future documentation and assessment of the hepialid fauna for this region, as with any other part of India, is the lack of modern descriptions of type specimens. The inclusion of voucher collections of Hepialidae in future biodiversity surveys of northeastern India is to be strongly encouraged, particularly in the context of current and future environmental impacts affecting the sustainability of forest environments in the region.
