Arab Science Surges on Climate Goals but Trails Rich Nations in Raw Output

The Arab region has long been described as one of the most environmentally vulnerable corners of the planet, a band of countries stretching from the Atlantic coast of Morocco to the Gulf of Oman where water scarcity, extreme heat, desertification and rising seas converge. Yet a detailed new analysis of two decades of scientific publishing shows that the region’s research response to these pressures has been growing at a remarkable pace, even as it remains uneven, internationally dependent and far smaller in absolute terms than the output of Europe and North America. The study, published as an open-access review in the journal Discover Sustainability, offers the most comprehensive picture to date of how Arab science is performing against six of the United Nations Sustainable Development Goals that relate directly to environment and climate.

A team led by Latefa Ali Dardas of the University of Jordan examined Scopus-indexed publications classified through the 2025 SciVal Sustainable Development Goal mapping, covering the twenty-year period from 2005 to 2024. The six goals under scrutiny were SDG 6 on clean water and sanitation, SDG 7 on affordable and clean energy, SDG 11 on sustainable cities and communities, SDG 13 on climate action, SDG 14 on life below water and SDG 15 on life on land. Because a single paper can address more than one goal, the datasets are not mutually exclusive. Across all six, the researchers tallied 305,582 SDG-specific publication assignments for the Arab region, a figure they then benchmarked against the European Union’s 27 member states and against North America using a battery of bibliometric indicators.

The headline finding is growth. Output rose significantly for every one of the six goals, with the trend confirmed statistically using Kendall’s rank correlation and Sen’s slope estimation, both reported at p below 0.001. Clean energy research, mapped to SDG 7, dominated by sheer volume, accounting for 108,462 publications, more than a third of all assignments. But the fastest climber was climate action itself: SDG 13 recorded the highest compound annual growth rate of the six, at 29.8 percent per year. That figure captures a region that has, over two decades, transformed climate science from a marginal activity into one of its most rapidly expanding research fronts, driven in part by the acute exposure of Arab countries to heat extremes, drought and water stress.

Volume, however, tells only part of the story. When the authors normalized output by population and by gross domestic product, a more nuanced picture emerged. In absolute terms and per capita, Arab output remained below that of the EU27 and North America across all six goals. Yet when output was scaled by economic size, the Arab region actually outperformed both benchmarks on every goal, publishing more SDG-related papers per unit of GDP than its wealthier counterparts. The authors are careful about interpretation: higher GDP-normalized output indicates substantial publication activity relative to economic scale, but it does not necessarily mean the region’s research systems are more efficient. It may simply reflect that smaller economies devote a comparatively large share of their limited research capacity to these pressing topics.

Leadership within the region is heavily concentrated. Saudi Arabia and Egypt topped the table in absolute publication output, a reflection of their large university systems and, in the Saudi case, substantial investment in energy and water research. The picture flips when the lens changes. After normalization by population, Qatar rose to prominence, its small population making its per-capita productivity stand out. After GDP normalization, Tunisia and Lebanon emerged as leaders, suggesting that countries with modest economic resources are nonetheless extracting impressive research productivity from their systems. This cross-country variation is one of the study’s central messages: the Arab region is not a monolith, and any attempt to strengthen its environmental science base must account for radically different national capacities, funding levels and institutional structures.

Perhaps the most striking result concerns quality as measured by citation impact. The region’s Field-Weighted Citation Impact, a metric that compares the citations a paper receives against the average for similar papers in the same field and year, exceeded the world benchmark of 1.00 for every one of the six goals. The values ranged from 1.26 for life below water to 1.89 for climate action, meaning that the average Arab climate-science paper was cited nearly twice as often as the global norm for its field. The region also logged 132,597 publication assignments in first-quartile journals and 46,458 assignments within the global top 10 percent citation percentile. For a region often assumed to lag in research quality, these numbers suggest that the work that does get published is competitive on the world stage, even if marked differences persist between individual countries.

The engine behind much of that impact appears to be international collaboration. Between 51.3 and 64.5 percent of the region’s SDG-related papers involved international partners, depending on the goal, and this share increased significantly over the two decades studied. By contrast, national collaboration, meaning co-authorship across institutions within the same country, accounted for only about 16 to 18 percent of output, and collaboration indexed between academia and industry was a mere 1 to 3 percent. The authors read these figures through the lens of sustainability knowledge systems: the region is globally connected but nationally fragmented. Its researchers plug readily into international networks, often with European or North American groups, yet the domestic and regional ties that would embed science in local policy, industry and practice remain thin.

That thinness matters for a practical reason. The study’s authors explicitly caution that the patterns they document indicate selective research strengths rather than overall regional parity or demonstrated policy impact. A high citation score earned through international co-authorship does not automatically translate into better flood defenses in Alexandria, more efficient desalination in the Gulf, or stronger conservation policy in the Maghreb. With academic-corporate collaboration hovering near one to three percent, the pathway from laboratory findings to commercial and governmental application is largely missing. The paper argues that this gap calls for differentiated capacity-building tailored to each country’s starting point, stronger national and regional research networks, and broader mechanisms for translating published knowledge into sustainability action on the ground.

The methodological machinery behind these conclusions is worth noting for what it reveals about modern research assessment. Rather than relying on keyword searches alone, the team used the 2025 SciVal SDG classification, an algorithmic mapping that assigns publications to goals based on their content, allowing consistent comparison across twenty years and dozens of countries. Trend significance was tested with non-parametric statistics suited to skewed bibliometric data, and the benchmarking design, pitting the Arab region against the EU27 and North America simultaneously, avoids the common pitfall of comparing a developing region only against itself. The trade-off is that SDG mappings are approximations, and publication counts measure research activity rather than real-world outcomes, a limitation the authors acknowledge implicitly by framing their findings as evidence about knowledge systems rather than about sustainability itself.

Still, the overall portrait is one of a research system in motion. Over twenty years, Arab scientists have built a substantial and fast-growing body of work on the environmental challenges that most threaten their region, and the international visibility of that work, judged by citation impact and journal quality, is strong. The unfinished agenda is integration: connecting the region’s researchers to one another, to domestic industry and to the policymakers who must implement the Sustainable Development Goals by 2030. With climate pressures intensifying across the Middle East and North Africa, the study suggests that the region’s scientific raw material is increasingly in place. What remains is to convert a rising publication curve into durable environmental resilience, a task that will depend less on how much Arab science publishes and more on how well it connects to the societies it aims to serve.
