‘Climate change’ the phrase of the century
Hi and welcome to my blog Water & Environmental Change in Africa, which
will explore themes relating to climate change, the acceleration of the
hydrological cycle, climate injustice, land-use change, agricultural practices,
and adaptive strategies within the African continent. Before we begin, it’s
relevant that I explain who I am, and my reason for writing this blog series. My
name is Bianca, and I’m a Geography student. I think of myself as a physical
geographer, mostly because science has always made sense to me, however, understanding
environmental change requires both a physical and human geography perspective, one
that incorporates the socio-economic, cultural and political as well as
hydrology. For today’s blog I’ll be presenting a simplified introduction to
climate change and then draw attention to its effects which are already
drastically impacting parts of Africa.
Undoubtedly everyone has heard of climate change, but do we all
understand its implications beyond global warming? Put simply environmental change will consist of extreme weather events
manifested as floods, droughts and tropical cyclones, hurricanes and heat waves
happening more frequently and more intensely. This is caused by the acceleration of the water cycle due to rising temperatures and
consequently increased evapotranspiration. These effects will vary according to
topography and climate; however, they are predicted to drastically impact tropical regions in particular. This is relevant when
discussing the African continent, seeing as a high percentage of the
continent’s climate is tropical; and is most affected by water and food scarcity; and safe water access issues. This is representative of
the ‘climate injustice’ phenomenon, where countries least
responsible for climate change suffer the most drastic consequences.
Environmental change - It’s happening NOW!
The vast majority of climate change discussions conclude with setting goals for the future, with nations pledging new more ambitious
goals all the time and affording themselves extensions on the deadlines they
have failed to meet. I would argue that this portrays climate change as
something that will come to pass in the FUTURE and takes away from acknowledging
the urgency of its effects that are happening NOW. For instance, what has been
called East Africa’s most severe drought in 40 years has been happening in Kenya,
Ethiopia and Somalia since 2020 and was even declared a ‘natural disaster’ by the Kenyan government in 2021. Despite
a history of droughts in the east African region, this extreme
drought event has been attributed to the La Niña phenomenon being affected by
climate change. Within the
region, La Niña induces droughts, however due to climate change its effects
have been amplified causing the rainy season to fail for 3 consecutive years. Another example of extreme weather cause by
climate change is south-east Africa where tropical storms have become more intense and frequent due
to higher ocean temperatures. Just this spring Mozambique, Malawi and Madagascar
were affected by three storms or cyclones (Tropical Storm Ana, Tropical Storm Dumako and Tropical Cyclone Gombe). These tropical storms collectively claimed the lives of almost
100 people, affected thousands and destroyed roughly 220,400ha of cropland in Mozambique
alone, and severely damaged
infrastructure.
Concluding thoughts
Hopefully you’ve enjoyed reading this short introduction to
environmental change and the brief examples of its effects in Africa. In the
coming posts I’ll be discussing the links to water related issues such as water
and food scarcity and access to safe water and adaptive strategies. See you next
time!
