Rewind: Climate-proofing Hyderabad #IndiaNEWS #Columns
By Dr Ramesh Chenamaneni
In recent years, the India Meteorological Department (IMD) has been issuing long-range rainfall forecasts for four divisions, namely: North Eastern India, Central India, North Western India and Peninsular India. Given the large spatial variation of rainfall and soils within these divisions, farmers in different sub-regions are unable to utilise these higher scale predictions for cropping decisions to adapt to climate variability.
Moreover, the capacity of the agricultural extension system to create and disseminate location-specific climate forecast-based advisories is at best sub-optimal. Therefore, there is a need to invigorate the current system and bridge the gap in the timely flow of knowledge information based on climate forecast to support the decisions of stakeholders along the agri-food value chain to mitigate climate impacts on agriculture.
For Hyderabad, a comprehensive assessment of the future impacts of climate change is missing, an obstacle to an efficient urban planning process. This article discusses critical issues related to climate change, scientific predictions for the Deccan region as well as challenges for policymakers, planners and administrators. It also proposes specific recommendations for a climate-proof Hyderabad region.
Monsoon Prediction over Northern Telangana

According to the Potsdam Institute for Climate Impact Research in Germany, the Indian Summer Monsoon (the Southwest Monsoon) is likely to reach Northern Telangana on June 15. Intermittent rains may appear during June 14-20. With high probability, a dry spell occurs between June 20 and 29. Continuous monsoon rainfalls are expected after June 29. The uncertainty of the dates is +/- 4 days. (see figure)
Predictions for Hyderabad Deccan Region
The Indo-German Project on Sustainable Hyderabad, led by this author, in which 60 scientists worked for 8 years on different subjects — taking the analysis of 100 years of rainfall and other data at Begumpet — could make for the first time very clear long-term climate change projections and their implications for the city and the Deccan region of Telangana.
Climate change is widely conceived as a global problem where solutions are drawn at a global scale, but it is the multitude of actors within nations who act upon various mitigation strategies
Climate change projections depend on global CO2-emission scenarios, best described by a high (A2, business as usual) and low (B1, global emission reduction from about 2035 on) global emission future. The level of certainty of our climate system representations for Hyderabad was assessed by their degree of consensus with 17 independent climate models (provided by the Intergovernmental Panel on Climate Change).
