Mapping for sustainable development: The Open Data for Resilience Mapathon

Lorenzo Piccio's picture

On Wednesday, November 14, we joined more than 170 volunteers at the World Bank’s Washington, D.C. headquarters to draw little red boxes on a map of Alajo—a small town in the coastal metropolis of Accra, Ghana.

Some might find tracing a map of a city 8,500 kilometers away to be a surprising way to spend an afternoon, but there are good reasons for it. The boxes represented buildings, and they will go on to become invaluable geospatial data that will help the residents of Accra prepare for and respond to flood risk. Home to over two million people, Ghana’s capital city is highly vulnerable to flooding. In 2015, torrential rainfall left much of the city underwater—affecting 53,000 people and causing an estimated US$100 million in damages.

In just a little over two hours, the volunteers made over 3,000 edits to the map of Alajo, complementing the work of local teams in Ghana that are leading data collection efforts in the field. Once validated by more experienced mappers, the data collected will help guide improvements to Accra’s solid waste disposal management system, and also inform the upgrading of settlements vulnerable to flooding.

Can modern technologies facilitate spatial and temporal price analysis?

The International Comparison Program (ICP) team in the World Bank Development Data Group commissioned a pilot data collection study utilizing modern information and communication technologies in 15 countries―Argentina, Bangladesh, Brazil, Cambodia, Colombia, Ghana, Indonesia, Kenya, Malawi, Nigeria, Peru, Philippines, South Africa, Venezuela and Vietnam―from December 2015 to August 2016.

The main aim of the pilot was to study the feasibility of a crowdsourced price data collection approach for a variety of spatial and temporal price studies and other applications. The anticipated benefits of the approach were the openness, accessibility, level of granularity, and timeliness of the collected data and related metadata; traits rarely true for datasets typically available to policymakers and researchers.

The data was collected through a privately-operated network of paid on-the-ground contributors that had access to a smartphone and a data collection application designed for the pilot. Price collection tasks and related guidance were pushed through the application to specific geographical locations. The contributors carried out the requested collection tasks and submitted price data and related metadata using the application. The contributors were subsequently compensated based on the task location and degree of difficulty.

The collected price data covers 162 tightly specified items for a variety of household goods and services, including food and non-alcoholic beverages; alcoholic beverages and tobacco; clothing and footwear; housing, water, electricity, gas and other fuels; furnishings, household equipment and routine household maintenance; health; transport; communication; recreation and culture; education; restaurants and hotels; and miscellaneous goods and services. The use of common item specifications aimed at ensuring the quality, as well as intra- and inter-country comparability, of the collected data.

In total, as many as 1,262,458 price observations―ranging from 196,188 observations for Brazil to 14,102 observations for Cambodia―were collected during the pilot. The figure below shows the cumulative number of collected price observations and outlets covered per each pilot country and month (mouse over the dashboard for additional details).

Ghanaian firms experience improved access to finance and electricity but challenges remain

The private sector continues to be a critical driver of job creation and economic growth. However, several factors can undermine the private sector and, if left unaddressed, may impede development.  Through rigorous face-to-face interviews with managers and owners of firms, the World Bank Group’s Enterprise Surveys benchmark the business environment based on actual experiences of firms.
 
This blog focuses on Ghana, where 720 firms were surveyed covering six business sectors—(i) Food, (ii) Chemicals, Plastics, & Rubber (iii) Basic Metals, Fabricated Metals, Machinery & Equipment (iv) Other Manufacturing (v) Retail (vi) Other Services.


Use of financial services for investments and working capital on the rise
According to the 2012 Ghana Enterprise Surveys (ES), 21% of firms used banks to finance investments (vs. 16% in 2007) and 25% used banks to finance working capital (vs. 21% in 2007). However, while access to financial services has improved, it is still lower compared to the average for around 135 countries with ES data. The corresponding global averages for bank finance for investments and working capital are 25% and 30%, respectively. Moreover, in Ghana, 23% of the firms surveyed had a bank loan or line of credit, compared to the global average of 34%.

 
 

How do we manage revisions to GDP?

Soong Sup Lee's picture

Gross Domestic Product (GDP) estimates are some of the most heavily requested and used data published on data.worldbank.org.  And as many users notice, the estimates are sometimes revised, occasionally  resulting in large changes from previously published values. Why do revisions happen, what information do we publish about those revisions, and where do you find it?
