Malawi, One of the world’s poorest states is battling droughts and floods

LIKE MOST Malawians, Wema Kaloti lives off the land. She grows maize on her family plot in Kamwendo, a village in the south of the country. But farming is getting harder as rainfall grows erratic. “Sometimes a lot, sometimes a little,” she says, glancing at the sky. Yields have dwindled. A hectare that once produced 20 sacks of maize now brings in seven. “There is not enough to sustain ourselves.”

Malawi is one of the poorest countries in the world. GDP per capita is lower in just five other states. Fully 71% of Malawians earn below the international poverty line of $1.90 per day. The bulk of the labour force work in agriculture. Improving Malawians’ lot, therefore, depends on making farming more productive or developing better ways of making a living. Both tasks are made more difficult by climate change.

Malawi is especially vulnerable to rising temperatures and mercurial rainfall. Most farmers in the country are smallholders. Four in every five grow maize. Almost all of them rely on a single rainy season. If it is disrupted, their livelihoods are at risk.

And disruption is on the way. Research summarised by Future Climate for Africa (FCA), a research consortium, points to two trends. The first is rising temperatures. By 2040 there may be more than 100 days a year above 30°C, compared with about ten today. The second is that while there may be fewer rainy days in the future, when it does rain, it is more likely to pour. This is a recipe for floods, droughts and shorter rainy seasons.

This sort of weather is already increasingly common. In 2015 there were both drought and floods, and a year later further drought. Maize production fell by 30% in 2015, then an additional 12% in 2016, when 6.7m (out of a country of 18.1m) needed food aid. In 2018 Lake Chilwa, in south-east Malawi, dried up completely. Residents of Chisi Island, in the middle of the lake, no longer needed canoes to reach the mainland.

In Zomba district, the region that includes the lake and Kamwendo village, climate change has had profound effects on the economy. Maize yields have slumped as the onset of the rainy season has moved from early October to mid-November. Rice fields near Lake Chilwa have flooded. Livestock farming has become harder with less water and feed. Around Lake Chilwa, the drying of the lake forced 7,000 fishermen to seek work elsewhere, mostly on Lake Malawi, which covers a fifth of the country.

It is not just climate change that is hurting farming. A growing population has meant dwindling farm sizes; today the average plot is 0.8 hectares, less than the area of a football pitch. Their soils are being degraded because they are farmed too intensively, and often using damaging practices. Nearly 40% of agricultural land has soil that is too acidic for decent yields. Malawian maize farmers get only 11-28% of the potential yield from the crop, according to the World Bank. Widespread deforestation, often by desperate farmers who need to sell wood for extra income, has made it harder to manage water flows.

There are some efforts afoot to adapt to climate change while improving land management. In Kamwendo, Ms Kaloti is part of a “farmer field school” supported by the Food and Agricultural Organisation, a UN agency. Farmers like her are experimenting with faster-growing varieties of maize and growing banana trees in gullies to lessen the effects of floods.

At Lake Chilwa, Sosten Chiotha of the University of Malawi has been leading a similar project. Farmers have doubled yields by improving the soil through mulching and using seeds that can grow in a shorter rainy season. Tree-planting has helped to protect rice fields from drowning. Solar-powered fish-dryers have quickened the process of preparing tiddlers for market. Mr Chiotha has set up a “weather chasers” WhatsApp group to raise awareness of incoming storms.
