A quiet corner of Lower Manhattan holds a stark reminder of a devastating past. Tucked away in Battery Park City, down Vesey Street toward North End Avenue, lies the Irish Hunger Memorial. This unique public artwork, a carefully arranged landscape of stones, soil, and moss, offers a contemplative space overlooking the Hudson River, commemorating the Great Famine that irrevocably altered Ireland’s history.
The famine, which began in the mid-19th century, resulted in the deaths of at least one million Irish people and spurred mass emigration, particularly to cities like New York. What’s striking is the disproportionate level of commemoration afforded to the Irish famine compared to other, equally or more deadly, instances of widespread starvation throughout history. While over 100 memorials stand in Ireland and around the globe to remember this tragedy, famines like the 1943 Bengal famine in India or the Great Chinese Famine of 1959-1961 receive far less public recognition.
This disparity is a sobering thought. Historical records indicate that approximately 140 million people have died of famine since 1870. Looking further back, famines were a tragically common occurrence, claiming even greater percentages of populations. A particularly brutal famine in Northern Europe during the early 14th century is estimated to have killed as much as 12 percent of the region’s inhabitants in just a few years. For millennia, the precariousness of food supply was a constant threat to human survival.
Today, while hunger remains a pervasive issue, outright famines are thankfully rarer. And crucially, these modern instances are far more often the result of political failures and systemic issues than of natural crop failures. This represents one of humanity’s greatest achievements – a triumph often overlooked. But can we maintain this progress in the face of new challenges?
A Global Harvest: Reaching Unprecedented Levels of Food Production
The outlook for global food security is, surprisingly, positive. Current projections indicate the world is poised to produce more grain than ever before. The UN’s Food and Agriculture Organization (FAO) forecasts record levels of cereal crop production – including wheat, corn, and rice – during the 2025-’26 growing season. Perhaps even more encouraging is the global stocks-to-use ratio, currently around 30.6 percent, meaning we are producing nearly a third more of these essential crops than we currently consume.
The US Department of Agriculture’s August report echoes this optimism, predicting a record US corn crop, coupled with a record yield – the amount of crop grown per acre. This yield increase is particularly significant, as it demonstrates our ability to produce more food on less land. While the FAO Food Price Index has seen a slight increase this year, it remains nearly 20 percent below its peak during the early stages of the war in Ukraine.
Zooming out reveals a long-term trend of improvement. Average calories available per person worldwide have steadily climbed from roughly 2,100-2,200 kcal/day in the early 1960s to nearly 3,000 kcal/day by 2022. Simultaneously, cereal yields have tripled since 1961. These two converging trends – increased food availability and enhanced agricultural productivity – have largely lifted humanity out of the shadow of the Malthusian trap.
The Seeds of Change: A ‘Green Revolution’ and Beyond
How did we achieve this remarkable progress? The answer lies in a series of agricultural innovations, often collectively referred to as the ‘Green Revolution.’
It began with the seed itself. Short-straw varieties of wheat and rice, developed to maximize fertilizer uptake, were a crucial first step. Hybrid seeds further boosted yields, followed by the introduction of genetically modified crops in the 1990s. Today, technologies like CRISPR allow breeders to precisely edit plant genes, accelerating the development of more resilient and productive crops.
But seeds alone aren’t enough. Fertilizer is essential. Historically, farmers relied on limited natural sources of nitrogen, like guano – the accumulated excrement of seabirds and bats – a resource that sparked a literal “guano rush” in the 19th century. However, in 1912, Fritz Haber and Carl Bosch revolutionized agriculture with their process for synthesizing nitrogen fertilizer. The Haber-Bosch process is arguably the most important invention of the 20th century, with half of today’s food production dependent on it.
Water is another critical component. Irrigated farmland has more than doubled since 1961, now providing 60 percent of the world’s cereal crops and half of all calories consumed globally. Highly productive agricultural regions, like California’s Central Valley, would be impossible without extensive irrigation systems. Irrigation technology continues to evolve, improving efficiency and minimizing water waste.
Finally, efficient logistics and global trade networks ensure that food can be transported from surplus regions to areas facing shortages. This interconnected system plays a vital role in mitigating the impact of localized crop failures.
The Persistent Challenge: Why Hunger Still Exists
Despite these advancements, hunger remains a global challenge. While the world produces enough calories to feed everyone, a healthy diet remains unaffordable for billions. The World Bank estimates that around 2.6 billion people cannot afford a nutritious diet. This number has seen a slight decrease in recent years, but the situation is worsening in sub-Saharan Africa.
Modern famines are rarely caused by a lack of food production; they are overwhelmingly the result of political instability and deliberate obstruction of access. The devastating famines in Gaza and Sudan, currently threatening the lives of over 25 million people, are tragic examples of man-made access failures in a world of abundance. (The recent peace deal in Gaza, however, offers a glimmer of hope for improved aid delivery as reported by the New York Times.)
Climate change also poses a significant threat. While basic crop harvests have so far proven resilient, climate scientists warn that risks to food security will increase with rising temperatures, particularly through heat waves, droughts, and simultaneous disasters affecting multiple breadbasket regions. Adaptation strategies – smarter agronomy, stress-tolerant crop varieties, and efficient irrigation – can mitigate losses up to around 2 degrees Celsius of warming. Beyond that threshold, our options become increasingly limited.
Finally, trade restrictions can exacerbate food insecurity. The 2007-2008 food price crisis was not primarily caused by production failures, but by political decisions to restrict exports, leading to price spikes that disproportionately impacted the poor. This precedent is concerning given recent calls for increased tariffs and trade barriers.
What role do you think international cooperation plays in ensuring global food security? And how can individuals contribute to a more sustainable and equitable food system?
Frequently Asked Questions About Global Food Security
- What is the biggest threat to global food security today? Political instability and conflict, which disrupt supply chains and prevent access to food, are currently the most significant threats.
- How has technology impacted food production? Innovations like genetically modified crops, precision agriculture, and improved irrigation techniques have dramatically increased food production and efficiency.
- Is climate change impacting food production? While current harvests are largely resilient, climate change poses a growing risk to food security through increased frequency of extreme weather events.
- What is the ‘Green Revolution’ and why was it important? The ‘Green Revolution’ refers to a period of agricultural innovation in the mid-20th century that led to significant increases in crop yields, helping to avert widespread famine.
- What can individuals do to support food security? Reducing food waste, supporting sustainable agriculture, and advocating for policies that promote equitable access to food are all important steps individuals can take.
The Irish Hunger Memorial serves as a poignant reminder of the devastating consequences of scarcity. But it also stands as a testament to humanity’s remarkable progress in overcoming this age-old challenge. After millennia of vulnerability to famine, we have built a food system capable of feeding eight billion people and consistently setting new harvest records. Despite the challenges that lie ahead, this is a story worth remembering and celebrating.
