How can researchers better connect the social, economic, and governance dynamics that shape long-term climate futures?
New research from the Frederick S. Pardee Institute for International Futures, published in Nature Communications, expands the socioeconomic foundation available to researchers using the Shared Socioeconomic Pathways (SSPs)—the community-developed framework that underpins much of today's long-term climate and sustainable development research.
Using International Futures (IFs), Pardee's integrated assessment model, the research team developed open-source SSP projections spanning 188 indicators across 188 countries through 2150. The projections connect population, economic development, governance, conflict, infrastructure, health, education, public spending, and other interconnected systems within a single, internally consistent modeling framework.
By bringing these assumptions together, the research addresses a longstanding challenge in scenario analysis: many long-term projections rely on separate models with different underlying assumptions. The new IFs-based projections provide researchers and practitioners with a transparent foundation for exploring risks, trade-offs, adaptive capacity, and policy choices whose effects may unfold over decades.

United Nations Industrial Development Organization has released a new policy brief, The Future of Jobs in an Era of Demographic and Technological Transformation, co-authored by Pardee’s Taylor Hanna. The brief serves as a follow-up to UNIDO’s latest Industrial Development Report, which was supported by Hanna and Pardee Research Associate Bido Ibrahim. Drawing on projections from the International Futures model, the analysis explores how demographic change and automation will reshape global employment by 2050. It highlights stark regional differences, with developing economies facing growing job creation pressures and advanced economies confronting higher risks of automation-driven displacement. Under a moderate automation scenario, global demand for new jobs could grow to one billion—underscoring the need for forward-looking, context-specific policy responses.

Understanding future dynamics and trends in human and natural development is foundational for creating appropriate policy strategies to address planetary and development challenges. Here, we present a protocol for adding exogenous series for key variables, such as the shared socioeconomic pathways, to the database of the International Futures (IFs) integrated model. We describe steps for installing IFs and the SQLiteStudio software, understanding the IFs database, importing series, running the model, and extracting results.

This study, “Land Degradation and Human Development in Yemen,” was commissioned by UNDP in 2024 as part of a collaboration with the Frederick S. Pardee Institute for International Futures, Josef Korbel School of Global and Public Affairs, University of Denver and climate researchers. Yemen is frequently said to be experiencing one of the worst development and humanitarian crises in the world after more
than ten years of ongoing conflict. At the same time, it is among the countries most vulnerable to climate change and for decades has faced a worsening water crisis as well as land degradation (including deterioration of historical terracing systems), desertification and soil erosion. This report seeks to better understand how the above-mentioned phenomena could affect economic and human development in Yemen on immediate, medium and long-term timescales.
The report explores the links between climate change, land degradation and desertification, conflict, and human development outcomes in Yemen. This report begins with a review of the literature of the drivers, context, and intervening factors around land degradation and desertification in Yemen so far. This is followed by an analysis of historical subregional data on land degradation and climatic variables within
the country. Turning toward the socioeconomic effects, the report first reviews literature on the pathways through which desertification can alter agricultural production and otherwise affect economic and human development. Finally, the report uses integrated modelling techniques and scenario analysis using the International Futures (IFs) model to explore the effect of degradation and restoration pathways on future development in Yemen. The IFs model has previously been applied to assess the effect of ongoing conflict in Yemen on human development and to examine possible recovery pathways in the Impact of War trilogy of reports and the Impact of Climate Change on Human Development produced by UNDP and the Frederick S. Pardee Institute for International Futures.

Yemen has been experiencing an exceptional phase and highly complex conditions for ten years due to a coup by the Houthi terrorist militia against the state. One of the consequences of this war has been the collapse of the state and the redirection of development and growth trajectories into the negative for many years, with Yemen falling in all international economic, humanitarian, and social indicators. However, despite this difficult reality, the resilience and cohesion of Yemenis, along with the sincere support from brothers and friends, have been fundamental in normalizing the situation, restoring stability, and resuming the building of state institutions. Despite all the challenges, including the ongoing war and difficult economic conditions, there are efforts being made to restore building and development, with national consensus on strengthening institutional work and developing tools to interact with the world and integrate into the visions of development and prosperity of the region and the world, and to address the consequences of the war. The economic file represents a top priority in the government's agenda and its general program, including achieving sustainable development goals and enhancing economic resilience. Five main priorities have been set for the government's work in the coming phase: (a) restoring the state and achieving sustainable peace, (b) combating corruption and enhancing transparency and accountability, (c) achieving financial and administrative reform, (d) developing economic resources, and (e) maximizing the benefits from external aid and grants and directing them according to the needs and priorities of the government. Through these five priorities, we will strive to achieve tangible and clear progress towards the sustainable development goals, and we will harness all possible energies for this purpose.

Even before the COVID-19 pandemic, the world was not on course to meet key Sustainable Development Goals (SDGs) including SDG 1 (No Poverty) and SDG 2 (Zero Hunger). Some significant degree of additional effort was needed before the pandemic, and the challenge is now greater. Analyzing the prospects for meeting these goals requires attention to the combined effects of the pandemic and such additional impetus. This article assesses the impact of the COVID-19 pandemic on progress toward the SDGs and explores strategies to recover and accelerate development. Utilizing the International Futures (IFs) forecasting system and recognizing the near impossibility of meeting the goals by 2030, three scenarios are examined through to 2050: A pre-COVID-19 trajectory (No COVID-19), the current path influenced by the pandemic (Current Path), and a transformative SDG-focused approach prioritizing key policy strategies to accelerate outcomes (SDG Push). The pandemic led to a rise in extreme poverty and hunger, with recovery projected to be slow. The SDG Push scenario effectively addresses this, surpassing the Current Pathand achieving significant global improvements in poverty, malnutrition, and human development by 2050 even relative to the No COVID-19 path. The findings emphasize the need for integrated, transformative actions to propel sustainable development.

Gendered analysis of the impact of climate change on poverty, productivity and food insecurity. In UN Women Data Hub. https://data.unwomen.org/publications/gendered-analysis-impact-climate-change-poverty-productivity-and-food-insecurity
The Frederick S. Pardee Institute for International Futures partnered with UN Women to provide the long-term scenario modeling behind A Gendered Analysis of the Impact of Climate Change, Poverty, Productivity, and Food Insecurity. Using the International Futures (IFs) model, Pardee researchers examined how climate change may deepen existing gender inequalities through its effects on poverty, agricultural productivity, and food security. The analysis highlights how gender-responsive investments in education, social protection, and climate resilience can help reduce disparities and strengthen progress toward sustainable development, demonstrating the value of integrated futures modeling for evidence-based policymaking.
