## ARTICLE:

Madagascar's economy is at a crossroads. Long-term GDP growth projections through 2030 suggest resilience, with real output expected to expand at a 3–4% compound annual rate—positioning the island nation among Africa's moderate growth performers. Yet recent climate catastrophe threatens to derail this trajectory. Cyclone Gezani's passage through the island in late 2024, claiming at least 31 lives and devastating agricultural and infrastructure assets, underscores a critical investment risk that macroeconomic forecasts often underweight: climate volatility.

The island's historical GDP narrative reveals structural fragility. From 1980 to 2020, Madagascar's real growth averaged 3.1% annually—respectable on paper, but volatility was endemic. Three major drought episodes (1992, 2016, 2022) and recurring cyclone seasons have repeatedly truncated expansionary cycles, dragging aggregate growth below potential. The 2020 COVID-19 contraction shrank GDP by 7.1%, followed by only partial recovery through 2023. Now, as investors eye Madagascar's untapped mineral wealth (graphite, rare earths) and tourism upside, Gezani's impact resurrects a hard question: **Can Madagascar's economy truly sustain 4% annual growth while absorbing climate shocks every 2–3 years?**

## What Does Cyclone Gezani Mean for Madagascar's Near-Term Growth?

Cyclone Gezani struck during the austral summer agricultural cycle, destroying crops in the south and southeast—regions where vanilla, rice, and cassava provide livelihoods for 70% of the rural population. Infrastructure damage, particularly to ports and roads in Fianarantsoa and Toliara provinces, will disrupt commodity exports and delay foreign exchange inflows. The World Bank estimates that major cyclones cost Madagascar 0.5–1.5% of annual GDP in direct damages and lost productivity. In a 3–4% growth environment, a single storm can wipe out the entire year's gains. The 2024–2025 fiscal year forecast now carries downside risk; analysts are revising growth estimates downward from 3.8% to 3.2%.

## Which Sectors Are Most Vulnerable?

Agriculture remains Madagascar's economic spine, contributing 24% of GDP and employing 70% of the workforce. Cyclones devastate subsistence farms faster than commercial estates can diversify. Vanilla production—which generates 5% of export revenue—is already under stress from regional competition; cyclone-induced crop loss compounds margin pressure. Mining (nickel, graphite) and tourism are less directly affected but face indirect headwinds: supply chain delays, labor migration from damaged zones, and investor risk aversion. Construction, however, may see a temporary boost as reconstruction spending kicks in through 2025.

## How Should Investors Recalibrate Risk?

Madagascar's medium-term growth story (2025–2030) hinges on structural reforms—tax revenue stabilization, port modernization, electricity grid expansion—and mineral sector investment. The graphite and rare-earth potential is real and supply-critical for global EV demand. Yet cyclone frequency is accelerating; climate modeling suggests a 40% increase in Category 3+ storms by 2035. Smart investors should demand climate hedges: infrastructure guarantees, political-risk insurance, and diversified export baskets. Companies betting on Madagascar must price in a 0.5–1% annual "climate tax" on returns and build redundancy into supply chains.
