  "account": "The Government of Togo launched the Novissi emergency cash program on 8 April 2020. On 2 November 2020 it extended it to rural areas using a machine-learning pipeline built with UC Berkeley and IPA researchers. Satellite imagery produced poverty estimates for every canton to rank the poorest. Within eligible cantons a model trained on mobile-phone metadata predicted each subscriber's consumption to decide who was paid. Beneficiaries self-registered by USSD and received mobile-money installments of 8,170 CFA (women) or 7,000 CFA (men). The World Bank and Government of Togo report 138,531 rural beneficiaries from November 2020 to August 2021, funded by GiveDirectly (US$10 million). The Nature evaluation found phone-based targeting reduced exclusion errors by 4–21% relative to geographic alternatives.",
