Abstract
Botswana is an arid country endemic to drought. The major water supply in the capital Gaborone, the Gaborone Reservoir, has received a failed status early this year due to diminishing water levels which have fallen below six percent of the total potential volume in 2014. However, there seems to be no official consensus as to what has caused this extreme decrease in volume. Water scarcity can have great impacts in regards to the economy, development and national security of a country and it is important to grasp the cause of the problem in order to solve it in the most efficient way. By analysing data time series for temperature, rainfall and consumption as well as performing a spatial analysis over the catchment area it was possible to... (More)

Poor data resolution and a lack of statistical significance mean that no concrete conclusions can be drawn. In order to sustain a sustainable water future, it is important that water conservation is promoted and that the second phase of the North South Water Carrier Project (with the purpose of pumping water from reservoirs in eastern Botswana and South Africa to Gaborone) keeps to the original timeline and fixes the faults within the pipeline.

Torka är mycket vanligt i Botswana. I huvudstaden Gaborone har Gaboronedammen klassats som ett misslyckande eftersom vattennivån har sjunkit till under sex procent av den potentiella volymen under 2014. Det finns inte någon officiell enighet om vad som har orsakat denna extrema volymminskning. Vattenbrist kan ha negativa konsekvenser för ett lands ekonomi, utveckling och till och med för den nationella säkerheten eftersom grannländer ofta tycker olika när det gäller vem som ska få utnyttja delade vattendrag. Det är viktigt att förstå orsaken till volymminskningen för att lösa problemet på bästa och effektivaste sätt. Under studien har både en rumslig analys och en analys av tidsserier för data gälande nederbörd, temperatur och konsumtion... (More)

Det är viktigt att förstå orsaken till volymminskningen för att lösa problemet på bästa och effektivaste sätt. Under studien har både en rumslig analys och en analys av tidsserier för data gälande nederbörd, temperatur och konsumtion genomförts. Detta har gjort det möjligt att se vilka förändringar som har skett sedan Gaboronedammen konstruerades 1965. På grund av brister i dataupplösning och trender utan statistisk signifikans så går det inte att dra några slutsatser. För att uppnå en hållbar vattentillgänglighet i Gaborone i framtiden så är det väsentligt att vattenvård främjas och att vattenförsörjning till Gaborone från Gaboronedammen kompletteras med pålitlig vattentillförsel från andra dammar i Botswana, dvs. NSCWP rörledningarna lagas och underhålls.
