Measuring economic destruction in Syria from outer space

2051
How is Syria’s civil conflict affecting the economy? This column analyses data on night-light intensity measured by satellites to assess the extent of the destruction of economic activity across the country. Without a strong programme of economic rebuilding when the conflict finally ends, the return of approximately 5.6 million registered refugees to Syria will not happen any time soon.

In a nutshell

Data on night-light intensity suggest huge destruction in the Syrian economy as a result of the civil conflict.

There is considerable regional variation in the magnitude of destruction, ranging from 18% in Damascus to almost 95% in Idlib.

The destruction has spilled over into neighbouring countries with relatively weak states and institutions, such as Iraq.

The refugee crisis is a growing concern for humanity. According to figures from the United Nations Refugee Agency, one in every 108 people on the planet is ‘displaced’; 20 people were forced to leave their home every minute during 2016, which corresponds to around 29,000 people per day (UNHCR, 2016).

As of today, the total number of displaced people around the world is approximately 70 million. Since the civil conflict began, Syria has been the major country of origin for refugees.

Research on Syrian refugees mostly focuses on the impact of refugee flows on host countries. The main outcomes of interest include employment, wages, consumer prices, housing prices and rents, health status, crime rates, schooling and firm openings in major host countries such as Jordan, Lebanon and Turkey. (For some examples, see Tumen, 2016; Balkan and Tumen, 2016; Ceritoglu et al, 2017; Del Carpio and Wagner, 2015; Fallah et al, 2018; and Altindag et al, 2018.)

Developed countries are also concerned with a possible movement of refugees – from either Syria or these primary host countries – towards the West. Governments care about the political economy consequences of refugee inflows. As a result, most of the ‘refugee debate’ in economic research is centred on the wellbeing of natives of host countries.

But with a few exceptions, economists seem to have entirely ignored what has happened in Syria itself. Aside from focusing on the reaction of host countries, this negligence is also due to a lack of systematic and healthy data on the state of the Syrian economy since the conflict began.

We are using data provided by the National Geophysical Data Center of the United States to compare the night-light intensity in Syria before and after the conflict began. Economists have recently started to use night-light data measured by satellites (see, for example, Henderson et al, 2012). The data act as a proxy for local economic activity, exhibiting a strong correlation with other major welfare indicators.

Using the Geographic Information System (GIS) methods adopted in related research, we construct indices combining the contrast and dispersion of night-lights. We report the time series evolution of these indices both for the entire country and at a province level.

Figure 1 demonstrates the rise and dramatic decline in the aggregate index based on data covering the period from 1994 to 2016. The figure raises three main points:

  • First, before the civil conflict, Syrian economy grew – as measured by our index – by approximately 4-5% a year.
  • Second, in the post-crisis era (from 2012 to 2016), the magnitude of economic destruction is above 75%.
  • Finally, GDP as of 2016 is more than 30% below its level in 1994.

These numbers suggest huge destruction in the Syrian economy as a result of the civil conflict.

Figure 2 shows the extent of economic destruction in some major Syrian provinces. Clearly, there is considerable regional variation in the magnitude of destruction, ranging from 18% in Damascus to almost 95% in Idlib.

The intensity of violence seems to be an important determinant both in terms of the magnitude of destruction and the volume of refugee outflows. Decline in night-light intensity in provinces such as Idlib, Aleppo and Daraa following the conflict supports this hypothesis. Note that province-level calculations are slightly less reliable than the aggregate figures.

Figure 3 compares the night-light intensity between two years: 2012 and 2016. Pink regions mark the night-lights that existed in 2012 but which had disappeared by 2016. It clearly demonstrates that the crisis has not only severely hit the Syrian economy, but it has also spilled over into Iraq in the form of jihadist terror.

The bottom line is that the civil conflict in Syria has destroyed the economy. The destruction has also spilled over into neighbouring countries with relatively weak states and institutions, such as Iraq.

Current debates about future prospects offer ‘the return of refugees to Syria after the conflict is over’ as a solution to the problems that host countries have been experiencing.

But our calculations suggest that the extent of economic destruction in Syria is so huge that even when the conflict is over, lack of economic opportunity will persist if external assistance to rebuild the country is not provided promptly. Without a strong programme of economic rebuilding, the return of approximately 5.6 million registered refugees to Syria will not happen any time soon.

Egypt’s labour market: new survey data for evidence-based decision-making

As Egypt faces substantial social and economic shifts, understanding the labour market is crucial for designing policies that promote employment and inclusive economic growth. This column introduces the latest wave of the Egypt Labor Market Panel Survey, which provides fresh, nationally representative data that are vital for examining these dynamics.

The evolution of labour supply in Egypt

Egypt stands at a critical point in its demographic and labour market evolution. As this column explains, while fertility rates have dropped, reducing long-term demographic pressures, the ‘echo generation’, children of the youth bulge, will soon enter the labour market, intensifying the need for policies to accelerate job creation. At the same time, participation in the labour force, particularly among women and young people, is declining, partly as a result of discouragement.

More jobs, better jobs and inclusive jobs: the promise of renewable energy

Among the many economic and environmental challenges facing the countries of the Middle East and North Africa (MENA), two stand out: the need for jobs and the need to combat the threat of climate change by moving away from reliance on fossil fuels. As this column explains, embracing renewable energy technologies presents an opportunity for the region to diversify its economy, mitigate the possible negative impacts of digital technologies on existing jobs, reduce its carbon footprint and create significant levels of employment, particularly for women and the youth, across a variety of sectors.

Sanctions and energy efficiency in Iran’s industries

What is the effect of economic sanctions on the energy efficiency of Iran’s industries? This column reports the findings of new research, which examines the impact of sanction intensity within industrial sub-sectors of the Iranian economy on their energy efficiency.

Towards a productive, inclusive and green economy in MENA

Decarbonisation of the global economy is a huge opportunity for countries in the Middle East and North Africa. As this column explains, they can supercharge their development by breaking into fast-growing industries that will help the world to reduce its emissions and reach net zero, as well as offering greater employment opportunities and new export lines. Micro, small and medium enterprises in the region can lead the transition to a cleaner and sustainable future, but this may require the formation of clusters of firms that overcome some of the constraints that their limited size could involve.

Poverty and plutonomy: measuring extreme bipolarisation in the Arab world

Inequality in the Arab world is not just a question of extreme poverty or extreme affluence: it’s about both. This column presents research that uses the lenses of both poverty analysis and plutonomy analysis to capture the extreme polarisation between the poor, who suffer from exclusion and deprivation, and the ultra-wealthy, who wield immense power over economic and political systems.

Participation of Arab countries in global value chains

To what extent are countries in the Arab region participating in the global value chains (GVCs) that now dominate world trade? What are the main determinants of engagement in GVCs? And what are the expected benefits for Arab countries from joining them? This column answers these questions, concluding that it is important to focus on the products in which countries both enjoy a natural comparative advantage and can increase domestic value added in the intermediate and final parts of the production process.

Growth in the Middle East and North Africa

What is the economic outlook for the Middle East and North Africa? How is the current conflict centred in Gaza affecting economies in the region? What are the potential long-term effects of conflict on development? And which strategies can MENA countries adopt to accelerate economic growth? This column outlines the findings in the World Bank’s latest half-yearly MENA Economic Update, which answers these questions and more.

The future of regionalism in the Arab world: a political economy view

The potential growth benefits of greater trade integration of the Arab countries, both within the Middle East and with the rest of the world economy, have long been discussed. But as this column explains, in the current climate of international political and economic relations, moves towards trade liberalisation and new or deeper trade agreements are unlikely to happen. Policy-makers in the region need to pursue alternative strategies to develop their economies.

Climate change: a growing threat to sustainable development in Tunisia

Tunisia’s vulnerability to extreme weather events is intensifying, placing immense pressure on vital sectors such as agriculture, energy and water resources, exacerbating inequalities and hindering social progress. This column explores the economic impacts of climate change on the country, its implications for achieving the sustainable development goals, and the urgent need for adaptive strategies and policy interventions.
