<p data-beyondwords-marker="58e5c196-11c1-4dc6-8a79-cf8c7f9b90b3">Africa is plagued by the consequences of poor economic planning. This is largely owing to the absence of accurate population data and geographical mappings.&nbsp;</p> 
<p data-beyondwords-marker="f43d226d-5cd8-41d4-80d7-e4a255d685d9">Google created a deep learning model that has been trained to determine the footprints of buildings from high-resolution satellite imagery. From there, the team created a large-scale open dataset that contains the outlines of buildings.</p>

<p data-beyondwords-marker="d6736846-d255-4d10-9092-6de4e15e30ef">According to Google researcher, William Ogallo, the major reason for the lack of food security in the country is that farming is largely not mechanised and rain-led. Hence, climate change has a significant impact on farming activities and food production.</p> 
<p data-beyondwords-marker="e028814c-02e8-4ca9-8e77-a54eeb26793d">In a bid to combat food security, the Google research team in Africa has built a forecasting tool on the strength of Artificial Intelligence and climate data. The goal is to provide frequent, precise and actionable food security predictions that empower farmers to plan and redistribute farming resources intelligently.</p> 
<p data-beyondwords-marker="d8ac115b-985b-479f-8e4a-d69f42d10cdf">William explained that the Google research team is passionate about helping farmers replace traditional farming methods with more effective and timely alternatives by providing accurate and frequent updates.</p>

<p data-beyondwords-marker="075cb51f-c2c3-4c3b-8a86-2e47442d9d1f">Scholars like Harvard’s Christina Pazzanese have raised concerns about the negative potentials of artificial intelligence In the hands of profit-driven private companies:</p> 
<p data-beyondwords-marker="50ecee03-e4b6-4a0b-b158-4338f80d56f4">“With virtually no government oversight, private companies use AI software to make determinations about health and medicine, employment, creditworthiness, and even criminal justice without having to answer for how they’re ensuring that programs aren’t encoded, consciously or unconsciously, with structural biases…”</p> 
<p data-beyondwords-marker="9e815a1d-f235-4a4c-b8b5-a460bf9761b2">Many worry whether the coming age of AI will bring new, faster, and frictionless ways to discriminate and divide at scale. In the same vein, some journalists in attendance were concerned about Google’s commitment to ethically handling the data of Africans that will be derived from the research projects.&nbsp;</p> 
<p data-beyondwords-marker="5c9c9fb8-edb3-4dd0-bb2b-5971f340d133">In response, Google developer, Perry Nelson reiterated the company’s commitment to create solutions that equally benefit all users and society.
