The Fifth International Conference on Climate Services (ICCS 5) is the premier global event for Climate Services Partnership in Africa. This year’s conference will take place in Cape Town, from February 28 until March 2, 2017, and focuses on capacity building and forging connections, with a particular focus on activities and persistent challenges in Africa.

Join our sibling research programme, Future Climate for Africa (FCFA) at the COP22 conference in Morocco:
At this event, South SouthSouthNorth and our partners, the Met Office, bring together a diverse panel of experts to discuss how Africa can increase its climate resilience in the face of increasing vulnerability to extremes.
This event will look at how innovative science and services are helping people across a broad range of contexts deal with key challenges.
Please feel free to forward this invitation on to any colleagues you think would be interested. We look forward to welcoming you.
If you are unable to attend in person, you can watch the live broadcast at 16:45 UTC.
A research team, led by Prof. Alan MacDonald of BGS, has been awarded research funding by the UK Natural Environment Research Council (NERC) for a study entitled “Monitoring the impact of the 2015/16 El Nino on rural water insecurity in Ethiopia: learning lessons for climate resilience“
El Niño is a prolonged warming of sea surface temperatures in the central and east-central Pacific that occurs irregularly at 3-6 year intervals. El Niño weakens the trade winds and alters the monsoon pattern which affects global weather patterns and typically results in drought conditions in Southern Africa and Southeast Asia and enhanced rainfall in Eastern Africa and South America.

Floods and droughts, feasts and famines: the challenge of living with an African climate has always been its variability, from the lush rainforests of the Congo to the extreme dry of the Sahara and Namib deserts. In north western Europe, drizzle and rain is generally spread quite evenly across the year, as anyone who has gone camping in British summer will tell you. But when annual rainfall happens within just a few months or weeks of the year then it is a massive challenge for farmers, towns and industry to access enough water through long dry seasons and to protect themselves and their land from flooding and mudslides when the rains come.
New research suggests that Africa’s aquifers could be the key to managing water better. Professor Richard Taylor at UCL explains: “What we found is that groundwater in tropical regions – and Sub-Saharan Africa in particular – is primarily replenished from intense rainfall events – heavy downpours. This means that aquifers are an essential way of storing the heavy rain from the rainy season for use during the dry season, and for keeping rivers flowing.”

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters.

There is the need to develop resilient agricultural water supplies as an essential first step to ensuring safe and reliable access to water by the rural poor, Ben Ampomah, Executive Secretary of the Water Resources Commission (WRC) of Ghana, has noted.
Mr Ampomah, therefore, identified groundwater has having a major role in meeting demand for increasing population in Africa, particularly sub-Saharan Africa.

Over 500 million people in sub-Saharan Africa (SSA) depend upon groundwater supplies, and this is set to rise dramatically. Safe and reliable access to water for the rural poor is a critical factor when reducing the proportion of people living in extreme poverty. As the majority of poor people in Africa depend upon farming for their livelihoods, developing resilient agricultural water supplies is an essential first step. Groundwater could provide a solution to this as there is the potential to tap into huge groundwater ‘reservoirs’ under the Sahel to provide water (http://www.bbc.co.uk/news/science-environment-17775211).

“A global analysis reveals growing societal dependence on the use of non-renewable freshwater resources that depletes groundwater reserves and undermines human resilience to water scarcity in a warming world”

In the short article, Prof. Taylor raises concern about groundwater depletion, as well as declining lake and river levels in many areas of the world, and that raises not only important scientific questions about how and why, but also a crucial problem for society.
Looking at recently published research he notes that there is increasing evidence of non-renewable freshwater use – basically more freshwater is being used and then either lost to evaporation or rendered useless by pollution and increased salt levels.
The finger of blame is pointed firmly at irrigation, but the demand for food will only rise in the coming years and decades. Groundwater, particularly in Africa, has great potential but its use is hampered by poor data and unreliable models and the joker card of climate change.
‘We need to better understand available groundwater storage and recharge responses
to the intensification of rainfall, which is expected to be especially strong in the tropics. Indeed, it is here where increases in freshwater use are projected to be most intense. We also need to reduce human dependence on nonrenewable fresh water through more efficient water use, particularly in irrigation, and by trading in ‘virtual water’, which reduces local freshwater use through the import of food and other products. If we continue along our present trajectory, “when the well runs dry we (shall) know the worth of water” ‘
The Grofutures Catalyst project, which has been green-lighted to become a Consortium project for the next 4-5 years, will tackle some of these issues in detail. More on this project will follow next year.
