RCT study on Bricks to Blocks: Information and coordination challenges for transitioning to a cleaner building technology

RCTField Experiment

Context

Acknowledging the detrimental effects of Fly Ash Bricks (FCBs), a policy was formulated in 2019 to entirely transition to the use of Soil-Stabilized Bricks (SSBs) for all construction and repair of government buildings, boundary walls, herringbone roads, and village roads by 2024-25. Despite the policy and provisions for incentives to facilitate its implementation, the adoption of SSBs in both public and private construction has remained remarkably low. For this reason, the policy implementation timeline was also shifted for two years. Earlier exploratory studies revealed some coordination and implementation issues in the project's implementation and less awareness and visibility of the alternative material. In this regard, this study will experimentally test if providing information and visibility of the use of the alternative material enhances the adoption of the green alternative. This could lead to policy suggestions to adjust the existing policy implementation strategy to increase implementation and help transition to sustainable material use in Bangladesh's construction sector.

Objective

The study will investigate constraints impeding the adoption of a green technology in government procurement while there are supportive policies behind it. Specifically, it will experimentally assess the effectiveness of interventions designed to address several barriers to achieving greater usage of soil-stabilized blocks (SSBs) over fired clay bricks (FCBs) as construction material in both publicly and privately procured projects.

Methodology

By employing a randomized controlled trial (RCT), this study will measure the impact of an “exposure intervention” for the procurement officials and contractors on the adoption of SSBs and the marginal effects of site visits, market linkage and skills training for workers as added interventions.

Climate Shocks and Internal Migration in Bangladesh: Causal Evidence and Origin–Destination Mapping for Proactive Policy

Difference-in-DifferencesPanel Data Analysis

Context

Bangladesh ranks among the world's most climate-vulnerable nations, facing recurrent cyclones, floods, riverbank erosion, and rising sea levels. These climate shocks displace millions of households, yet policy responses remain largely reactive—focused on post-disaster relief rather than anticipatory planning. While internal migration is a well-documented adaptation strategy, the causal relationship between specific climate events and migration decisions remains poorly understood. Existing studies often rely on cross-sectional data or lack the spatial granularity needed to trace where displaced populations relocate. Without robust origin–destination mapping and causal identification, policymakers cannot effectively allocate resources, plan infrastructure, or design social protection programs for climate-affected migrants. This study addresses these gaps by combining household panel data with satellite-derived climate exposure measures to establish causal links and map migration flows at the district level.

Objective

This study investigates the causal effect of major climate shocks—particularly cyclones and floods—on internal migration outcomes in Bangladesh. Specifically, it aims to: 1. Identify causal impacts: Estimate the effect of cyclone and flood exposure on household migration decisions using quasi-experimental methods. 2. Map origin–destination flows: Trace where shock-affected migrants relocate within Bangladesh and identify which receiving districts absorb climate migrants. 3. Inform proactive policy: Generate evidence to support anticipatory planning, targeted social protection, and infrastructure investment in high-risk and high-absorption areas.

Methodology

The study employs a Difference-in-Differences (DiD) design with staggered treatment timing, following the Callaway & Sant'Anna (2021) estimator to address heterogeneous treatment effects. Primary data sources include: - Bangladesh Integrated Household Survey (BIHS): A four-wave panel (2011, 2015, 2019, 2024) tracking the same households over time, capturing migration status, origin/destination, and socioeconomic characteristics. - IBTrACS Cyclone Database: Event-level cyclone tracks, intensity, and wind speed data from NOAA. - Sentinel-1 SAR Imagery: Satellite-derived flood extent mapping via Google Earth Engine. The analysis proceeds in three stages: (1) construct district-level climate exposure indices from satellite and meteorological data; (2) estimate causal effects of climate shocks on out-migration using panel fixed effects and DiD; (3) construct origin–destination migration matrices to visualize and analyze spatial flows.

Enhancing Economic Recovery Capacity of COVID-19-Affected Climate-Vulnerable Farmers Engaging in Dairy, Crop, and Vegetable Farming

Quasi-experimentalPSM

Context

The adverse impacts of climate change pose a significant threat to the sustainability of agricultural practices and the well-being of farming communities in Bangladesh. The compounding effects of the COVID-19 pandemic have further exacerbated these challenges by disrupting supply chains and leading to substantial economic losses. The project emphasizes on the provision of prompt assistance through providing essential resources and empowering farmers with knowledge, assets, and market access to boost the resilience of agro businesses affected by repercussions od COVID-19. By engaging the established BRAC Social Enterprises network, and aligning with key national strategies, including the Bangladesh Climate Change Strategy, the 8th Five Year Plan, and COVID-19 response strategies, this project works towards sustainable economic recovery for vulnerable farmers in the face of dual crises.

Objective

The key objective of the project is to improve the condition of the climate vulnerable farmers stricken by COVID-19 through supporting them with resources, cultivating adaptive farming skills and business strategies with market linkages. This ought to help them with a climate resilient economic recovery and establishing a network on a local level for sustainable trading practices.

Methodology

The impact evaluation for the programme will be conducted using a quasi-experimental method. Treatment sample lists were provided by the programmes and the comparison samples were selected from the adjacent locality based on the visible similarities to the treatment group households. Since the comparison sample was not selected randomly, there could be differences in characteristics between the treatment and comparison samples. To account for this non-random sample bias, propensity score matching (PSM) will be used to produce comparable comparison group to evaluate the impact of the programme interventions.

Exploring the Risk of Forced Labor and Human Trafficking Among Climate-Induced Displaced Populations Living in Urban Slums in Bangladesh

Mixed MethodsLongitudinal SurveyFGDKIIPhotovoice

Context

This study examines the material, social, and psychosocial impacts of climate-induced displacement on individuals and households who have relocated to urban slums in Bangladesh due to environmental disasters such as cyclones and river erosion. It explores how inadequate adaptation policies and poor planning force vulnerable communities to relocate to informal settlements where they face severe socio-economic challenges. These precarious conditions heighten the risk of exploitation, including forced labor and human trafficking, as displaced individuals struggle with limited access to resources, employment, and social protection in their new environments. The study aims to shed light on these vulnerabilities and inform more effective policies to support displaced populations.

Objective

The objective of this study is to explore the material, social, and psychosocial impacts of climate-induced displacement and migration on individuals and households who have relocated from their original residences, focusing on how these factors influence their well-being, access to resources, and social integration. Additionally, the study aims to identify the failures of adaptation policies and measures that contributed to the decision to relocate, such as inadequate infrastructure, poor planning, and insufficient local or national support for communities affected by climate change. Finally, the study will assess the vulnerability of displaced individuals who resettle in informal urban or peri-urban settlements to modern slavery and human trafficking, examining the socio-economic and environmental conditions that may increase their exposure to exploitation in these precarious living environments.

Methodology

This two-year study will employ an exploratory mixed-methods approach, combining qualitative and quantitative longitudinal data collection. The research will involve household quantitative surveys alongside qualitative methods such as focus group discussions (FGDs), key informant interviews (KIIs), case studies, and auto-ethnography. Photovoice will be used to capture the livelihood journeys and realities of individuals living in vulnerable locations where the risk of engaging in forced labor and human trafficking is significantly high.
