Uganda: Conventional Farming Has Worsened Food Insecurity in Uganda - Experts

Conventional farming, the practice of applying synthetic fertilizers and chemicals in gardens to increase crop yields, control pests and weeds has contributed to food insecurity in Uganda, experts say.

A section of Ugandan citizens do not know that they are directly responsible for the acute food shortages that they are experiencing. Essentially, they are their own worst enemy. Smallholder farmers regularly apply chemicals and synthetic fertilizers to control weeds, pests and multiply crop yields respectively.

Application of chemicals in gardens to kill weeds and pests not only has disastrous effects on human life, but also exhibits zero tolerance to living organisms in the soil, notably earthworms, bacteria, and fungi, which serve to improve aeration and a natural source of soil nutrients.

Worse still, these pesticides destroy the green pigment in plants, an important ingredient of manure after decomposition. According to the Global Hunger Index published by United States Agency for International Development (USAID) in 2022, many households and specific segments of the population in Uganda suffer from food insecurity and high levels of malnutrition.

The report indicates that 59%, 19% and 11% of households in the North East, Mid-North, and West Nile respectively consume one meal a day. The situation is not any better in central parts of Uganda, with a section of households seeing two meals a day as a miracle.

Other factors contributing to low yields, degradation of land resources through poor farming methods, characterized by spraying with chemicals to control weeds and pests were cited.

Ggwayambadde Fred Mukasa, a smallholder farmer in Kasaana village Nyendo-Mukungwe division in Masaka city, and an architect of agroecology among his contemporaries explains the dangers of spraying with chemicals to curb pests and weeds.

Not only are these chemicals dangerous to human life, he says, but also greatly contribute to soil degradation by cutting off humus production by living organisms, leading to gross infertility, erosion and consequently low yields.

His zeal to conserve nature during daily rounds carrying out farming on his 6-acre land, a practice he has embraced for years to curtail climate change and ensure sustainable food systems has been an inspiration to many, to follow suit.

"These drugs killing grass, and you spray, you are killing the chlorophyll. Formerly, our great grandparents used to cover this grass with soil when they are digging. Today, what we do because we are in a hurry is that we just get the herbicides, spray acres and acres, on the same day, you plant maize, and you look at the farmer as if he is a mad man or woman," remarks Ggwayambadde.

His farmland is an embodiment of several agroecology practices like beekeeping, intercropping, agroforestry, crop rotation, recycling and others, carefully designed in his quest to try to maintain a complex, but healthy interaction between living organisms and plants that predate on each other for the continued survival of the ecosystems, leading to sustainable agriculture.

An exuberant smallholder farmer, Ggwayambadde prides himself in incredibly abnormal coffee harvests as a result of the skillful application of organic fertilizers, which helps crops to withstand harsh weather conditions like drought.

"As you saw my coffee, the trees are just bending, bending, already I have harvested some. Else you would find the trees on the ground because of beekeeping and using these organic manure. Some farmers using these other fertilizers, synthetic fertilizers they are crying, because the rain was so small and their coffee is not as good as mine," testifies Ggwayambadde.

Stephen Katende Serunjogi, a principal technician at the department of agricultural production, School of Agricultural Sciences, Makerere University says that synthetic fertilizers are not dangerous to the soil per se, but smallholder farmers apply them wrongly, without carrying out soil fertility tests, intoxicating the soil further and contaminating water bodies.

"You have to carry out soil fertility tests, to know what nutrients are missing, in what quantity, when to apply them, if you don't do that, that's why people say that mineral fertilizers are bad," said Serunjogi.

He however remarked that organic manure works well in soil rejuvenation, as compared to synthetic fertilizers because it improves soil nutrient retention capacity and also food to micro-organisms which are important in humus production and earation.

"In the process of trying to rejuvenate the soil, there are measures which can be employed, and one of them if you look at the physical aspect, you have look at the structure of the soil, you have to incorporate some materials like organic matter which can be put in the soil so that the soil can improve in terms of organic aeration and nutrient retention, and these organic materials are the food for the microorganisms."

According to the report published by Food and Agriculture Organization (FAO) in 2012, plants, animals, and micro-organisms (fungi and bacteria) increase fertility of the soil, by helping in maintaining its structure and aeration.
