Introduction:  The sinking of the Deepwater Horizon drilling platform and the resulting discharge of millions of gallons of crude oil into the sea demonstrated graphically the challenge of environmental protection in the ocean waters shared by Cuba and the United States.

While the quest for deepwater drilling of oil and gas may slow as a result of the latest calamity, it is unlikely to stop. It came as little surprise, for example, that Repsol recently announced plans to move forward with exploratory oil drilling in Cuban territorial waters later this year.

As Cuba continues to develop its deepwater oil and natural gas reserves, the consequence to the United States of a similar mishap occurring in Cuban waters moves from the theoretical to the actual. The sobering fact that a Cuban spill could foul hundreds of miles of American coastline and do profound harm to important marine habitats demands cooperative and proactive planning by Washington and Havana to minimize or avoid such a calamity. Also important is the planning necessary to prevent and, if necessary, respond to incidents arising from this country’s oil industry that, through the action of currents and wind, threaten Cuban waters and shorelines.

While Washington is working to prevent future disasters in U.S. waters like the Deepwater Horizon, its current policies foreclose the ability to respond effectively to future oil disasters—whether that disaster is caused by companies at work in Cuban waters, or is the result of companies operating in U.S. waters.

Event Information

The start of the 21st century has been an auspicious period for global economic development. In the 1990s, a mere 13 emerging economies succeeded in growing at a speed at least twice that of the OECD countries, enabling rapid convergence on Western living standards. By the first decade of the 2000s, this number had mushroomed to 83. Accelerated rates of economic growth lay behind many of the recent success stories in global development, not least the fulfilment of the first Millennium Development Goal to halve the global poverty rate, five years ahead of the 2015 deadline. Yet in a number of places, growth has failed to take off, has undergone periodic reversals, or has benefited a few while leaving the majority short-changed.

On August 7-9, 2014, Brookings Global Economy and Development is hosting the eleventh annual Brookings Blum Roundtable on Global Poverty in Aspen, Colorado. This year’s roundtable theme, “Jump-Starting Inclusive Growth in the Most Difficult Environment,” brings together global leaders, entrepreneurs, practitioners, and public intellectuals to discuss what strategies exist for promoting inclusive economic growth in settings where standard prescriptions are not feasible or sufficient as well as what the comparative advantages are of different actors seeking to improve the prospects for inclusive growth and how can they most effectively collaborate with each other to increase their impact.

There is a lot of hope around the potential of Big Data—massive volumes of data (such as cell phone GPS signals, social media posts, online digital pictures and videos, and transaction records of online purchases) that are large and difficult to process with traditional database and software techniques—to help achieve the sustainable development goals. The United Nations even calls for using the ongoing Data Revolution –the explosion in quantity and diversity of Big Data—to make more and better data usable to inform development analysis, monitoring and policymaking: In fact, the United Nations believes that that “Data are the lifeblood of decision-making and the raw material for accountability. Without high-quality data providing the right information on the right things at the right time; designing, monitoring and evaluating effective policies becomes almost impossible.” The U.N. even held a “Data Innovation for Policy Makers” conference in Jakarta, Indonesia in November 2014 to promote use of Big Data in solving development challenges.

Big Data has already played a role in development: Early uses of it include the detection of influenza epidemics using search engine query data or the estimation of a country’s GDP by using satellite data on night lights. Work is also under way by the World Bank to use Big Data for transport planning in Brazil.

During the Data for Development session at the recent NetMob conference at MIT, we presented a paper in which we jump on the Big Data bandwagon. In the paper, we use mobile phone data to assess how the opening of a new toll highway in Dakar, Senegal is changing how people commute to work (human mobility) in this metropolitan area. The new toll road is one of the largest investments by the government of Senegal and expectations for its developmental impact are high. In particular, the new infrastructure is expected to increase the flow of goods and people into and out of Dakar, spur urban and rural development outside congested areas, and boost land valuation outside Dakar. Our study is a first step in helping policymakers and other stakeholders benchmark the impact of the toll road against many of these objectives.

Assessing how the impact of the new toll highway differs by area and how it changes over time can help policymakers benchmark the performance of their investment and better plan the development of urban areas.

The Dakar Diamniadio Toll Highway (in red in Figure 1), inaugurated on August 1, 2013 is the first section (32 km or 20 miles) of a broader project to connect the capital, Dakar, through a double three-lane highway to a new airport (Aeroport International Blaise Diagne, AIBD) and a special economic zone, the Dakar Integrated Special Economic Zone (DISEZ) and the rest of the country.

Note: The numbers indicate the incidence of increased inter cell mobility and were used to calculate the percentage increase in mobility.

The cost of this large project is estimated to be about $696 million (FCFA 380.2 billion or 22.7 percent of 2014 fiscal revenues, excluding grants) with the government of Senegal having already disbursed $353 million. The project is one of the first toll roads in sub-Saharan Africa (excluding South Africa) structured as a public-private partnership (PPP) and includes multilateral partners such as the World Bank, the French Development Agency, and the African Development Bank.

In our study, we ask whether the new toll road led to an increase in human mobility and, if so, whether particular geographical areas experienced higher or lower mobility relative to others following its opening.

Using mobile phone usage data (Big Data), we use statistical analysis in our paper to approximate where people live and where they work. We then estimate how the reduction in travel time following the opening of the toll road changes the way they commute to work.

As illustrated in the map of Figure 1, we find some interesting trends:

• Human mobility in the metropolitan Dakar area increased on average by 1.34 percent after the opening of the Dakar Diamniadio Toll Highway. However, this increase masks important disparities across the different sub-areas of the Dakar metropolitan areas. Areas in blue in Figure 1 are those for which mobility increased after the opening of the new road toll while those in red experienced decreased mobility.
• In particular, the Parcelles Assainies suburban area benefited the most from the toll road with an increase in mobility of 26 percent. The Centre Ville (downtown) area experienced a decrease in mobility of about 20 percent.

These trends are important and would have been difficult to discover without Big Data. Now, though, researchers need to parse through the various reasons these trends might have occurred. For instance, the Parcelles Assainies area may have benefited the most because of its closer location to the toll road whereas the feeder roads in the downtown area may not have been able to absorb the increase in traffic from the toll road. Or people may have moved from the downtown area to less expensive areas in the suburbs now that the new toll road makes commuting faster.

From these preliminary results (our study is work in progress, and we will be improving its methodology), we are encouraged by the fact that our method and use of Big Data has three areas of application for a project such as this:

Benchmarking: Our method can be used to track how the impact of the Dakar Diamniadio Toll Highway changes over time and for different areas of the Dakar metropolitan areas. This process could be used to study other highways in the future and inform highway development overall.

Zooming in: Our analysis is a first step towards a more granular study of the different geographic areas within the Dakar suburban metropolitan area, and perhaps inspire similar studies around the continent. In particular, it would be useful to study the socio-economic context within each area to better appreciate the impact of new infrastructure on people’s lives. For instance, in order to move from estimates of human mobility (traffic) to measures of “accessibility,” it will be useful to complement the current analysis with an analysis of land use, a study of job accessibility, and other labor markets information for specific areas. Regarding accessibility, questions of interest include: Who lives in the areas most/least affected? What kind of jobs do they have access to? What type of infrastructure do they have access to? What is their income level? Answers to these questions can be obtained using satellite information for land prices, survey data (including through mobile phones) and data available from the authorities. Regarding urban planning, questions include: Is the toll diverting the traffic to other areas? What happens in those areas? Do they have the appropriate infrastructure to absorb the increase in traffic?

Zooming out: So far, our analysis is focused on the Dakar metropolitan area, and it would be useful to assess the impact of new infrastructure on mobility between the rest of the country and Dakar. For instance, the analysis can help assess whether the benefits of the toll road spill over to the rest of the country and even differentiate the impact of the toll road on the different regions of the country.

This experience tells us that there are major opportunities in converting Big Data into actionable information, but the impact of Big Data still remains limited. In our case, the use of mobile phone data helped generate timely and relatively inexpensive information on the impact of a large transport infrastructure on human mobility. On the other hand, it is clear that more analysis using socioeconomic data is needed to get to concrete and impactful policy actions. Thus, we think that making such information available to all stakeholders has the potential not only to guide policy action but also to spur it.

La monnaie électronique a émergé dans les pays de l'Union Economique et Monétaire Ouest Africaine, à la faveur de l'adoption, en 2006, d'une Instruction de la Banque Centrale, instaurant un cadre réglementaire souple et incitatif pour l’exercice de cette activité. L'implication des opérateurs de télécommunications dans l'offre de services financiers basés sur la téléphonie mobile a donné,  dès 2009, une nouvelle dimension à cette activité par l'accroissement du nombre des utilisateurs et des volumes de transactions.

Une activité en expansion

A fin septembre 2015, 22 millions de personnes, soit près d'un quart de la population de l'Union, ont souscrit à des services financiers via la téléphonie mobile. Environ 30% de ces abonnés réalisent au moins une opération sur une période de 90 jours.

Près de 500 millions de transactions ont été aussi réalisées au cours des neuf premiers mois de l'année 2015. La valeur cumulée des transactions atteint 5000 milliards de FCFA (8,5 milliards USD) à fin septembre 2015. De septembre 2013 à septembre 2014, cette valeur est passée de 1000 milliards à 2068 milliards de F CFA, soit une hausse de 107%.

Le réseau de distribution des services financiers via la téléphonie mobile suit également cette tendance haussière, en passant de 93 621 points de services en 2014 à plus de 132 658 points de services à fin septembre 2015.

Le contexte socioéconomique de l'Union explique pour une large part, le succès des services de paiement via la téléphonie mobile. En effet, ce mode de prestation des services de transfert ou de paiement se révèle particulièrement adapté pour les personnes n'ayant pas accès au système bancaire classique, tout en offrant l'opportunité à des institutions non bancaires, en contrepartie de dépôt d'espèces, de mettre à la disposition des usagers une monnaie autre que fiduciaire, dont l'encours leur permet d'effectuer des transactions financières diverses.

L'implication croissante des opérateurs de télécommunications

Les partenariats entre les banques et les opérateurs de télécommunications occupent une place dominante sur le marché. En fin 2015, sur les 33 émetteurs de monnaie électronique sous licence, 25 appartenaient aux dits partenariats.

Au titre du modèle non bancaire, sept acteurs non bancaires ont été agréés pour émettre la monnaie électronique en qualité d'Etablissement de Monnaie Electronique (EME).[1]

Un cadre réglementaire rénové

A la faveur de l'expansion des services financiers via la téléphonie mobile et de l'implication croissante des opérateurs de télécommunication, la Banque Centrale a rénové son cadre réglementaire afin de renforcer la sécurité et la qualité des services de paiement adossés à la monnaie électronique. Les principaux axes d'amélioration portent sur:

• une responsabilisation accrue des émetteurs en clarifiant leurs rôles dans les partenariats avec des prestataires techniques. Ainsi, les activités de prestataire technique sont limitées, sous la responsabilité de l'émetteur, au traitement technique de la monnaie électronique ou à sa distribution. De même, les émetteurs demeurent responsables, de l’intégrité, de la fiabilité, de la sécurité, de la confidentialité et de la traçabilité des transactions réalisées par chacun de leurs distributeurs;


• une stimulation de la concurrence par la transparence de la tarification avec l'obligation faite aux émetteurs de publier leurs tarifs;


• la formulation d'exigences spécifiques en matière de gouvernance et de contrôles interne et externe pour les établissements de monnaie électronique, en exigeant l'honorabilité des dirigeants, le respect du secret professionnel et des audits réguliers des infrastructures;


• une protection accrue des détenteurs de monnaie électronique avec d'une part, le cantonnement des fonds dans  des comptes dédiés, et l'exigence d'une équivalence continue entre l'encours de monnaie électronique et les soldes des comptes de cantonnement et d'autre part, l'obligation de la mise en place d'un mécanisme de recueil et de traitement des réclamations des porteurs de monnaie électronique;


• le renforcement du dispositif de supervision, par la réduction des délais de reporting des activités des émetteurs à la Banque Centrale, et l'adoption de sanctions pour les infractions aux dispositions réglementaires.

L'offre de services financiers via la téléphonie mobile

L'offre de services financiers via la téléphonie mobile comprend trois catégories de services. Il s'agit des services qui impliquent l'usage des espèces (monnaie fiduciaire), de ceux qui sont effectués en monnaie électronique et des services dits de « deuxième génération ».

Le premier type de services concerne essentiellement les dépôts d'espèces ou rechargements de porte-monnaies électroniques, ainsi que les retraits. Ils représentent 24% des transactions effectuées par les utilisateurs. Les dépôts d'espèces sont prédominants et permettent aux clients d'approvisionner leurs comptes de monnaie électronique.

La monnaie électronique rechargée est utilisée à hauteur de 76%, prioritairement pour les achats de crédit téléphonique, les paiements de factures, l'exécution de transferts de personne à personne, de personne à entreprise et aux Administrations publiques. Les principaux services de paiement dans l'UEMOA sont liés au règlement des factures relatives à la consommation d'eau, d'électricité, l'abonnement à des chaînes de télévision satellitaires, l'achat de marchandises dans les grandes surfaces ou de carburant dans les stations-service.

Des paiements d'impôts et taxes auprès des Administrations publiques et le remboursement des échéances de microcrédit sont également effectués, mais de façon très marginale.

Dans l'UEMOA les services dits de « deuxième génération », à savoir la micro-assurance, la micro-épargne et le micro-crédit, font leur apparition. Leur développement pourrait constituer une opportunité de bancarisation des utilisateurs de ces services.

Enfin, un début d'interopérabilité est mis en œuvre sur la base de conventions bilatérales entre les acteurs, notamment en vue d’offrir des services de paiement transfrontaliers entre les Etats membres de l'Union.

Les défis à relever

L'examen de l’évolution des services financiers via la téléphonie mobile dans l'UEMOA fait ressortir quelques obstacles à un développement plus rapide de ces services financiers au sein de l'UEMOA. Il s'agit de:

• la faiblesse du taux d'utilisateurs actifs, en raison du coût élevé des services;
• la méconnaissance des services, du fait d'une éducation financière insuffisante;
• la faible digitalisation des circuits de paiement des Administrations publiques;
• l'insuffisance des partenariats entre les émetteurs bancaires et non-bancaires pour le développement d'une offre de services plus inclusifs, dits de « seconde génération »

En collaboration avec toutes les parties prenantes, la Banque Centrale a développé une stratégie d’inclusion financière visant à améliorer l’accès et l’utilisation de divers services financiers personnalisés et aux prix abordables. La mise en place de ces actions, comme décrite dans la stratégie d’inclusion financière conçue par la BCEAO, devrait résoudre les défis mentionnés ci-dessus.

Electronic money, or e-money, emerged in the countries of the West African Economic and Monetary Union (WAEMU) following the adoption, in 2006, of a Central Bank Instruction establishing a flexible regulatory framework aimed at encouraging e-money business. The activity expanded in 2009 with the involvement of telecommunications operators in the provision of mobile telephone-based financial services, which increased the number of users and the volume of transactions.

A growing business

At the end of September 2015, 22 million people, or nearly a quarter of the people in the union, subscribed to financial services via mobile phone. Approximately 30 percent of those subscribers carried out at least one transaction per 90-day period.

Some 500 million transactions took place over the first nine months of 2015. The cumulative value of the transactions was 5 trillion CFA francs ($8.5 billion) by the end of September 2015, a growth of 142 percent from September 2014. Between September 2013 and September 2014, this value grew from CFA 1 trillion to CFA 2.068 trillion, an increase of 107 percent.

The mobile phone financial services distribution network followed a similar upward trend, rising from 93,621 points of services in 2014 to more than 132,658 at the end of September 2015.

Figure 1. Trends in the value of transactions

The socioeconomic environment in the union goes a long way to explaining the success of mobile telephone payment services. Indeed, this method of providing money transfer or payment services is particularly well suited to people who lack access to the mainstream banking system, and also affords non-bank institutions the opportunity to offer users non-cash money against cash deposits, which can then be used for a variety of financial transactions.

The growing involvement of telecommunications operators

The market is increasingly dominated by partnerships between banks and telecommunications operators, which represented 25 of the 33 licensed or authorized e-money issuers at the end of December 2015. In the framework of this model, known as the bank model, the bank has responsibility for issuing the e-money.

The other seven non-bank institutions, under the non-bank model, are authorized to issue electronic money as “Electronic Money Institutions” (EMIs) [1].

In WAEMU, e-money issuers are supported by a regulatory framework that was revised in 2015 to ensure increased security and quality of payment services backed by electronic money.

Figure 2. E-money issuers in WAEMU

Note: DFS denotes microfinance institutions.

A revised regulatory framework

With the expansion of mobile phone financial services and the growing involvement of telecommunications operators, the Central Bank has revised its regulatory framework with the aim of enhancing the security and quality of payment services backed by electronic money. The most salient improvements must focus on:

• Increasing issuer accountability by clarifying users’ roles in partnerships with technical service providers. With this goal in mind, the activities of technical service providers have been restricted to technical processing or the distribution of e-money under the responsibility of the issuer. In addition, issuers are responsible for the integrity, reliability, security, confidentiality, and traceability of all transactions carried out by all of their distributors; Stimulating competition through transparent pricing with an obligation for issuers to publish their rates;


• Specific requirements in terms of governance and internal and external audits for electronic money institutions, standards of integrity on the part of the management, professional secrecy and regular infrastructure audits;


• Increased protection for bearers of electronic money, including keeping funds in dedicated accounts, requiring a constant equivalence between the amount of e-money and the balances in the dedicated accounts, and mandatory creation of a mechanism to take in and deal with complaints by bearers of electronic money;


• Reinforcement of the supervisory mechanism by reducing deadlines for reporting on issuers’ activities to the Central Bank and adopting sanctions for violations of regulatory provisions.

Provision of mobile-phone-based financial services

Mobile-phone-based financial services provided in WAEMU include three categories of services, namely services involving the use of cash (banknotes and coins), e-money services, and so-called “second generation” services.

The first type of service essentially involves deposits of cash or refilling of electronic wallets, as well as withdrawals. This type of service represents 24 percent of user transactions. Cash deposits predominate; they allow customers to provision their electronic money accounts.

Seventy-six percent of the funds deposited into e-money accounts are used, above all, for purchases of telephone credit, payment of bills, person-to-person money transfers, and money transfers from individuals to businesses and from individuals to government agencies. The main payment services found in WAEMU pertain to payment of water or electricity bills, payment of satellite television subscriptions, and purchases of goods in supermarkets or fuel at service stations.

Payments of taxes or income taxes to government agencies and payments of micro-loan installments are also made through mobile phone financial services, but are much less common.

So-called “second generation” services, namely micro-insurance, micro-savings, and micro-credit, are currently emerging in WAEMU. Their development could be an opportunity to provide access to the banking system for the users of the services.

Finally, interoperability is just beginning to be implemented based on bilateral agreements between stakeholders, particularly with a view to offering cross-border payment services between member states of the union.

Challenges

A review of the development of mobile phone financial services in WAEMU reveals some obstacles to the rapid development of this type of financial service within WAEMU. They include:

• a low number of active users, due to the high cost of the services;
• the fact that the services are not well known due to inadequate financial education;
• the low rate of digitization of government agencies’ payment systems; and
• insufficient partnerships between bank and non-bank issuers with a view to developing a more inclusive range of “second-generation” services.

In collaboration with all stakeholders, the Central Bank has developed a financial inclusion strategy to continuously improve, access to and use of diverse, tailored and affordable financial services. The implementation of these actions as described in the Central Bank of West African States (BCEAO) financial inclusion strategy should support the challenges mentioned above.

Event Information

Since the Rose Revolution in November 2003, Georgia has grappled with the many challenges of building a modern, Western-oriented state, including implementing political and economic reforms, fighting corruption, and throwing off the vestiges of the Soviet legacy. On the path toward a functioning and reliable democracy, Georgia has pursued these domestic changes in an often difficult international environment, as evidenced by the Russia-Georgia conflict in 2008.

On March 17, the Center on the United States and Europe at Brookings (CUSE) hosted President Mikheil Saakashvili to discuss Georgia’s approach to these challenges. A leader of Georgia’s 2003 Rose Revolution, Saakashvili was elected president of Georgia in January 2004 and reelected for a second term in January 2008.

Vice President Martin Indyk, director of Foreign Policy at Brookings, provided introductory remarks and Senior Fellow and CUSE Director Fiona Hill moderated the discussion. After the program, President Saakashvili took audience questions.

Event Information

Stability in Europe’s eastern neighborhood, already precarious, is being further strained. The political prospects of several countries, including Ukraine, Georgia, Turkey and Russia, remain unclear. The region is grappling with the fallout of the economic crisis, and Russia and Turkey, in particular, are threatened by the turmoil in the Arab world.

On April 13, the Center on the United States and Europe at Brookings (CUSE) hosted former European Union High Representative for Common Foreign and Security Policy Javier Solana for a discussion on how the European Union (EU) and NATO should engage with Europe’s strategic partners in the East and Southeast. As a former secretary general of NATO and secretary-general of the Council of the European Union, Solana offered insight into the prospects for future EU and NATO enlargement, the potential impact of the eurozone crisis on the region and how Europeans should attempt to cooperate with their neighbors in tackling global challenges.

Brookings President Strobe Talbott provided introductory remarks and moderated the discussion.
