Climate extreme indices in Tanzania for the period 1961-2015 are analyzed
using quality controlled daily rainfall, maximum and minimum temperatures
data. RClimdex and National Climate Monitoring Products (NCMP) software
developed by the commission for Climatology of the World Meteorological
Organization (WMO) were used for the computation of the indices at the respective
stations at monthly and annual time scales. The trends of the extreme
indices averaged over the country were computed and tested for statistical
significance. Results showed a widespread statistical significant increase in
temperature extremes consistent with global warming patterns. On average,
the annual timescale indicate that mean temperature anomaly has increased
by 0.69˚C, mean percentage of warm days has increased by 9.37%, and mean
percentage of warm nights has increased by 12.05%. Mean percentage of
cold days and nights have decreased by 7.64% and 10.00% respectively. A
non-statistical significance decreasing trends in rainfall is depicted in large
parts of the country. Increasing trend in percentage of warm days and warm
nights is mostly depicted over the eastern parts of the country including areas
around Kilimanjaro, Dar-es-Salaam, Zanzibar, Mtwara, and Mbeya regions.
Some parts of the Lake Victoria Basin are also characterized by increasing
trend of warm days and warm nights. However, non-statistical significant decreasing
trends in the percentage of warm days and warm nights are depicted
in the western parts of the country including Tabora and Kigoma regions and
western side of the lake Victoria. These results indicate a clear dipole pattern
in temperature dynamics between the eastern side of the country mainly influenced
by the Indian Ocean and the western side of the country largely influenced
by the moist Congo air mass associated with westerly winds. The results
also indicate that days and nights are both getting warmer, though, the
warming trend is much faster in the minimum temperature than maximum
temperature.

Climate change cannot be addressed by a single nation. We must lay emphasis on a regional approach since whatever happens in our individual nations affects the entire region. This means that we must act both individually and collectively, especially in instituting effective and sufficient measures towards mitigation against the adverse effects of climate change.

This report considers how issues related to climate change can be incorporated into the third phase of the Tanzania Social Action Fund (TASAF III). By linking social protection (SP) , climate change adaptation (CCA) and disaster risk reduction (DRR), the report identifies how TASAF can be made ‘climate smart’ by enabling it to better withstand the pressures from a changing climate while at the same time strengthening people ’s resilience , and maximising opportunities for climate finance. A roadmap is presented that identifies opportunities to incorporate these findings into TASAF III in a systematic, comprehensive and realistic way

Tanzania hosts a variety of ecosystems, including mountain, dry lands, wetlands, coastal and marine ecosystems, many of which are trans-boundary (e.g. the Lake Tanganyika ecosystem, which is shared between four countries). These ecosystems directly support the livelihoods of many Tanzanians and much of the country’s economy as a whole, providing goods and services including food, water, medicine, building materials, fuel and numerous natural attractions that support tourism.
The pressure placed on Tanzania’s ecosystems has been steadily growing as the human population increases, the economy expands, and more ecosystem goods and services are appropriated, traded and consumed. Ecosystem fragmentation resulting from land use changes, overgrazing, artisanal mining, the destruction of watersheds through deforestation, extensive pollution, wildfires, and the inadequate levels of management capacity, institutional coordination and participation of key stakeholders are all contributing to the degradation and destruction of numerous ecosystems across Tanzania (NEMC, 2006). The result is declining soil fertility, reduced water flow and loss of biological diversity. Global anthropogenic climate change is placing additional strain on already degraded ecosystems, which in turn has consequences for human communities using, in various ways, the goods and services that these ecosystems offer.
