The International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) was developed in the early 1990s to explore the long term challenges facing policymakers in reducing hunger and poverty in a sustainable fashion. The IMPACT model has been expanded and improved repeatedly to respond to increasingly complex policy questions and the state-of-the-art of modeling. See documentation of most recent update.

Currently, IMPACT is a network of linked economic, water, and crop models. At its core is a partial equilibrium multi-market economic model, which simulates national and international agricultural markets. The links to water and crop models support the integrated analysis of changing environmental, biophysical, and socioeconomic trends, allowing for in-depth analysis on a variety of critical issues of interest to policymakers at national, regional, and global levels.

Many publications and other resources based on IMPACT analyses are available below. Also available is an online visualization tool providing key results from recent IMPACT analysis in an easy-to-access format.

Adapting to climate change: The case of saline tolerant seed varieties in coastal Bangladesh

Adapting to climate change: The case of saline tolerant seed varieties in coastal Bangladesh

Salt water intrusion and rising soil salnity are threatening food and livelihood security of paddy farmers in coastal Bangladesh. Visible manifestations of these challenges are degraded soils and chronic decline in tradtional farming, as it is becoming an increasingly infeasible means of livelihood. Promoting saline-tolerant paddy varieties (STRV) has been one of the major focuses of the Bangladesh Rice Research Institute (BRRI) and the attention to the problem has been intensified in recent years through a partnerhsip with a consortium of CGIAR centers. Howewer, robust empirical analysis has hitherto been limited. Using farm level data, this paper analyzes the determinants and impacts of the adopting these new varieties. We use a multi-variate logit model to identify the constraints to adoption, and Propensity Score Matching (PSM) and Endogeneous Switching Regression methods to assess the impacts on yeilds, and net income of the paddy farmers. Results show that adopting saline-tolerant rice varieties raises crop yield by an average of 1 to 2 tons per hectare, equivalent to a net income increase of about US$100 per hectare of cultivated land. Yet, adoption rates remain low due to several institutional constraints and perhaps a lack of nudging farmers in the scaling up strategies. Robustness of the results are tested, and the implications are discussed.

Systematic risk profiling: A novel approach with applications to Kenya, Rwanda, and Malawi

Systematic risk profiling: A novel approach with applications to Kenya, Rwanda, and Malawi

This paper uses machine learning, simulation, and data mining methods to develop Systematic Risk Profiles of three developing economies: Kenya, Rwanda, and Malawi. We focus on three exogenous shocks with implications for economic performance: world market prices, capital flows, and climate-driven sectoral productivity. In these and other developing countries, recent decades have been characterized by increased risks associated with all these factors, and there is a demand for instruments that can help to disentangle them. For each country, we utilize historical data to develop multi-variate distributions of shocks. We then sample from these distributions to obtain a series of shock vectors, which we label economic uncertainty scenarios. These scenarios are then entered into economywide computable general equilibrium (CGE) simulation models for the three countries, which allow us to quantify the impact of increased uncertainty on major economic indicators. Finally, we utilize importance metrics from the random forest machine learning algorithm and relative importance metrics from multiple linear regression models to quantify the importance of country-specific risk factors for country performance. We find that Malawi and Rwanda are more vulnerable to sectoral productivity shocks, and Kenya is more exposed to external risks. These findings suggest that a country’s level of development and integration into the global economy are key driving forces defining their risk profiles. The methodology of Systematic Risk Profiling can be applied to many other countries, delineating country-specific risks and vulnerabilities.

Dietary quality and nutrition: Past progress, current and future challenges

Dietary quality and nutrition: Past progress, current and future challenges

Prior to the onset of the COVID-19 pandemic in 2020 and the military coup in 2021, Myanmar was experiencing a period of rapid economic growth and transformation in the wake of economic and political liberalization. Between 2005 and 2017, average annual growth in real GDP per capita was 7.8 percent, making Myanmar the fastest growing economy among the Association of Southeast Asian Nations (ASEAN) countries. Strong growth was accompanied by a halving of the national poverty rate between 2005 and 2017 from 48.2 to 24.8 percent (CSO, UNDP, and World Bank 2019). COVID19 and the economic and political shocks affecting the country since 2021 have led to an economic contraction: 2021 saw an 18 percent drop in real GDP per capita; in 2022, real GDP per capita was estimated to be 15 percent lower than in 2019 (World Bank 2022). The impacts on poverty were even more dire. A high-frequency panel phone survey of mothers and young children in urban Yangon and the rural Dry Zone revealed incomes collapsing during the COVID-19 lockdowns and further income losses in the wake of the February 2021 military takeover (Headey et al. 2022). Prices rose dramatically, with the consumer price index rising by 20 percent between July 2021 and July 2022 (MOPF 2022), while food prices rose by 34 percent over the same period and by about 50 percent between December 2021 and December 2022. Nationally, a variety of different poverty indicators suggest that between 40 and 50 percent of the population was living in poverty in 2022 —poverty rates similar to those found between 2005 and 2010.
