She Is a Gold Digger: Women Strike It Big in East Africa - 0 views

  • Tanzania alone sits on an estimated 2,222 metric tons of gold and boasts the third-highest reserves of the metal in Africa. But while the failure of these reserves to translate into wealth for ordinary people has led to populist moves – Tanzania’s President John Magufuli has demanded foreign mining firms pay higher taxes if they want to continue exporting — the problem may lie, in part, elsewhere. While women account for about 40 to 50 percent of Africa’s 8 million artisanal miners, their average income is significantly lower than that of their male counterparts, according to the African Center for Economic Transformation.
  • That has a spillover effect on communities. An established body of economic research, including by organizations like the Organization for Economic Cooperation and Development (OECD), has shown that economic empowerment of women translates into greater benefits for their families and communities than similar levels of earnings for men. That’s a phenomenon that groups working with gold miners in East Africa are witnessing also.

    "With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay
