As a developing economy, India has numerous developmental aspirations. How India meets these goals without worsening the climate crisis is at the heart of CSTEP's work. Addressing climate change and enabling a secure and sustainable future for Indian citizens require an overhaul of previous paradigms on development and resource utilisation. This is reflected in our work on developing low-carbon trajectories for development with an emphasis on nature-based solutions.
We are working with state governments across India to build capacity on risk and vulnerability assessments to inform their respective action plans on climate change. The transition from fossil fuels to renewable energy is crucial to achieving a secure and sustainable future. CSTEP's studies explore the possibility of a greater integration of renewables in the energy sector.
Atmospheric aerosols and inhalable particle number count during Diwali in Dehradun
This work presents the effects of fireworks display during Diwali on the short-term elevation of atmospheric aerosols and associated particle deposition in human respiratory tract at Dehradun, located in the foothills of the Himalayas. During Diwali in the years 2017 and 2018, the real-time particle number count (PNC) and particulate matter (PM) with the aerodynamic diameter of 0.01 to 35 μm were measured using an aerosol spectrometer.
Impact of COVID-19 lockdown on the fine particulate matter concentration levels: Results from Bengaluru megacity, India
Leveraging the COVID-19 India-wide lockdown situation, the present study attempts to quantify the reduction in the ambient fine particulate matter concentrations during the lockdown (compared with that of the pre-lockdown period), owing to the highly reduced specific anthropogenic activities and thereby pollutant emissions. The study was conducted over Bengaluru (India), using PM2.5 (mass concentration of particulate matter having size less than or equal to 2.5 µm) and Black Carbon mass concentration (BC) data.
The Role of Carbon Capture and Storage in India’s ‘Hard To Abate’ Industries
Carbon dioxide levels have hit a record high yet again despite the slowdown caused by the coronavirus lockdowns globally. Based on estimates by the GHG platform, heavy industries comprising cement, steel, chemicals, and aluminium and heavy-duty transport such as shipping, trucking, and aviation are responsible for more than a third of the carbon dioxide emissions in India.
Climate Change Risks to Rainfed Agriculture in Karnataka: Implications for Building Resilience
Climate change increases strain on agriculture systems through changes in the magnitude, distribution, and timing of rainfall; rise in temperature; and an increase in the frequency of extreme weather events. In Karnataka, agriculture is the key contributing sector for the state’s economy. Despite its importance, agriculture in the state is limited by the availability of irrigation (only 31.2%) and uncertainty in rainfall distribution. These factors greatly hamper the agricultural productivity of the state.
Syncing phenology phase and canopy spectral reflectance of common tree species of four forest covers in India
Variability in the leaf phenology of tropical trees impacts their growth. How phenology of tree species responds over rainfall gradient is relevant to study in the light of current climatic changes. Airborne visible and infrared imaging spectrometer-next generation (AVIRIS-NG) spectral datasets have been considered for this study as they not only provide wider area of coverage, but also high spatial and spectrally resolved output.
