For most of us, not knowing what the weather is going to do might at worst result in a soggy barbecue or a washed-out cricket or football match. For a farmer in the developing world it could result in the loss of an entire harvest which, at best, makes life that much harder or, at worst, brings on financial ruin or considerable human suffering. If enough farmers over a wide geographical area are affected, widespread famine becomes a very real possibility.
Africa is home to around 700 million people who depend on the land for their living -- that's a staggering 70 percent -- and three-fifths of those are subsistence farmers who generally produce just enough food to support their families. Despite its dominance, subsistence farming comes with its fair share of challenges, which include anything from a lack of access to appropriate tools and domesticated work animals to poor-quality soil and lack of irrigation. If that wasn't enough, climate change is set to join the list.
A recent Global Humanitarian Forum report estimated that climate change is responsible for some 300,000 deaths each year and more than US$100 billion worth of economic losses, mainly because of shocks to health and agricultural productivity. Sub-Saharan Africa accounts for close to a quarter of these losses, and is the region at the most immediate risk of droughts and floods. Agricultural yields in some areas are expected to fall by 50 percent as early as 2020.
In this troubled environment farmers are grateful for anything that makes their lives that little bit easier, and in recent years mobile technology has joined the hoe and plough as a valuable tool. Mobile phones are allowing farmers to connect to markets and connect with each other, opening up new opportunities to increase yields, efficiencies and incomes. Numerous initiatives have emerged as a result, including more recently Grameen's launch of a suite of services in Uganda that includes one aimed specifically at empowering farmers with targeted, actionable information.
A new initiative is set to take all this to a new level and exploit Africa's mobile infrastructure in an entirely new way. Despite its size, the African continent suffers from an acute shortage of weather monitoring stations, boasting just a couple of hundred active stations today, a figure which represents a network eight times below the World Meteorological Society's minimum recommended standard. Compare this to Europe, North America and Asia, which have several thousand each, and you can see the problem. Last month Global Humanitarian Forum, Ericsson, the World Meteorological Organization and mobile operator Zain announced the planned deployment of up to 5,000 automatic weather stations at existing cellular base stations across Africa. The first 19 stations alone more than double weather monitoring in the Lake Victoria region, where 5,000 people die every year as a result of storms and accidents.
The "Weather Info for All" initiative hopes to radically improve Africa's weather monitoring network not just today, but also in the face of the growing impact of climate change. More to the point, according to organizers it intends to "provide a massive increase in crucial information to predict and manage climate shocks." This is good news for Africa's 700 million farmers, if someone can figure out how to get this information directly to them at little or no cost.
One of the more interesting aspects of this initiative is how it could pave the way for an entirely new genre of ICT-based humanitarian projects. All manner of sensing devices could be placed across the mobile network, detecting everything from a rise in water levels that could lead to flooding, to an excess of smoke particles in the air that could indicate extensive bush fires. Other sensors could detect movement of distribution of wildlife or the density or health of vegetation, or areas of deforestation or desertification. We could leverage the two key advantages that mobile base stations give us, their ubiquity across many settled areas and the fact that they're wirelessly connected to each other.
Imagine if this data was collected and then geo-tagged, and then made freely available to anyone who may want to make use of it? Of course, advances in technology bring their fair share of new challenges. Poachers, for example, would love to be able to monitor and track elephant movements. But for the NGO community at large, access to real-time environmental data -- a trend that we're perhaps seeing the birth of with Africa's mobile-powered weather monitoring stations -- could take us into entirely new and exciting territory.
