Climate change is wreaking havoc on daily life in rural Tanzania, impacting everything from health and nutrition to agriculture and infrastructure. As floodwaters rise and harvests dwindle, aid organisations like World Vision are faced with unprecedented challenges in their efforts to support vulnerable communities. Chris Palmer reports from the ground in the Kilosa District.
The Struggles of Rural Communities
In the remote village of Madudumizi, pregnant mothers are experiencing significant changes to their lives thanks to the opening of a new clinic funded by World Vision. The facility, equipped with a deep borehole providing clean water, has drastically reduced the perilous journey mothers previously undertook to access healthcare. “Before, we had to walk for hours, crossing rivers that could be dangerous,” recounts Salma, a mother of four. Tragically, such journeys have previously cost lives.
World Vision’s “Ulaya” programme aims to uplift the lives of 27,000 people across 13 villages, focusing on health, nutrition, education, and access to clean water. In 2025, the organisation invested approximately $48 million (£35 million) in Tanzania, reaching around three million children. Despite Tanzania’s economic growth—6.2 per cent in early 2026—half of the population still survives on less than $3 a day, underscoring the critical role of NGOs in battling maternal mortality and malnutrition.
Climate Change Undermines Aid Efforts
However, the escalating climate crisis is beginning to unravel these hard-won gains. Prolonged periods of heavy rain and flooding have become the new normal, disrupting agricultural cycles and threatening infrastructure. “Until about 2019, we had predictable rainy and dry seasons,” explains Elisei Chilala, coordinator for the Ulaya Area Programme. “Now, climate change has made it impossible to know when to plant crops.” With 98 per cent of the local population relying on rain-fed agriculture, the stakes are high.
In the past year, World Vision has reported that major flooding events, once considered rare, have occurred multiple times. The Mkondoa River’s flooding has led to infrastructure damage and a sharp increase in illnesses like malaria and respiratory infections. Nurse Ida from the Madudumizi clinic notes, “The floodwaters have caused more malaria cases this year compared to last.”
Aid Reductions and Rising Vulnerability
Adding to the woes, foreign aid from wealthy nations has seen a significant decline, with a 26 per cent drop in 2025 compared to the previous year. This reduction is particularly concerning for Tanzania, which received $3.2 billion in aid during 2024. As funding becomes increasingly scarce, organisations like World Vision are grappling with the dual challenges of climate change and reduced financial support.
The community in Zombo village, where mothers are being trained in nutrition practices, is already feeling the impact. Despite improvements in knowledge about healthy eating, fears are mounting that failing harvests will thwart their efforts. “We are worried about the future,” says Rehema, a mother of five. “The weather is becoming more difficult, and we do not know what food we will have.”
Adapting to a New Reality
World Vision is adapting its approach in response to these challenges. The organisation is focusing on training farmers in efficient agricultural practices and providing seeds for climate-resilient crops. Leonard Slaa, a World Vision advisor, highlights the need for urgent action: “We are trying to transform practices so that they can withstand the influence of climate shocks.”
Despite the assistance, the impacts of climate change are accelerating faster than many can cope with. Reports of conflict between farmers and pastoralists over diminishing resources are becoming more common, reflecting a broader crisis that could have devastating implications for community stability.
Why it Matters
The situation in Tanzania serves as a stark reminder of the interconnectedness of climate change, humanitarian aid, and community resilience. As the climate crisis deepens, it threatens to reverse progress made in health, nutrition, and education, creating a cycle of vulnerability that could affect generations to come. The proactive measures taken by organisations like World Vision are vital, but urgent and sustained action is needed from both local and international communities to combat the escalating challenges. As climate-related disruptions continue to mount, the stakes have never been higher for those living in the frontlines of this global crisis.
