The National Climate Change Statistics Report, 2019 (NCCSR) is structured in five chapters. Chapter One presents overview of climate change in Tanzania and methodology for development of the NCCSR. Main statistical tables, charts and analysis for climate change are presented from Chapter Two to Chapter Four. Chapter Five focuses on mitigation and adaptation efforts undertaken by the Government of Tanzania to curb emissions of Green House Gases (GHGs) and build resilience against the impacts of climate change.
Statistics in Chapter Two analyses emissions of GHGs (Carbon Dioxide, CO2; Methane, CH4; and Nitrous Oxide, N2O). The national estimates indicate that, Tanzania has negligible emissions levels of GHGs in terms of total and per capita whereby per capita emissions are estimated at 0.2 tCO2e. The principal source of GHGs emissions in Tanzania is the Land Use, Land-Use Change and Forestry (LULUCF). Emissions from the LULUCF sector contribute about two-thirds of overall emission levels in Tanzania. Other sectors which contribute to greenhouse gas emissions in the country are Agriculture, Energy, Waste and Industrial Process and Product Use.
With regard to the use of Ozone Layer Depleting Substances (ODS), results reveal that, HC 600a is the most used ODS alternative in Tanzania. Its consumption increased from 232.6 MT in 2012 to 636.4 MT in 2015. Other ODS alternatives in great use are HFC-134a and R-717, with consumption increasing from 18.2 MT to 30.4 MT and 16.7 MT to 30.2 MT respectively between 2012 to 2015.
Statistics in Chapter Three show evidences of climate change in recent periods. The mean monthly maximum temperatures (28.5 °C) for the short period (2012- 2018) are slightly higher than the long term monthly means for 1981-2010 recorded at 28.2 °C which indicates an increasing pattern of temperature over the same shorter period. The data also indicate increased trends of precipitation in recent period. The monthly average rainfall (85.4 mm) observed for the short period of 2012 - 2018 is slightly higher than the monthly average rainfall (83.3 mm) recorded for the long term period, 1981-2010. In addition, there is a gradual rise of mean sea level from 1,992 mm in 2000 to 2,115 mm in 2019
