World Environment Day is the most important day celebrated by the United Nations designed to promote awareness and global action to protect our environment.
Through its projects, Morija is acting on this by promoting soil restoration, sustainable agricultural practices and biodiversity conservation.
The Family Bocage Fields project (CFB) encourages, for example, the beneficiaries to limit the use of chemicals such as pesticides, to the benefit of organic treatment.
Observation: intensive use of phytosanitary products
The intervention area of the CFB project which includes 7 villages around Nobéré, is an important cotton-growing region. The cultivation of cotton, which is highly sensitive to pest attacks, leads farmers to intensively use pesticides and insecticides. The problem is that this use is widespread among farmers who use these harmful products, unadapted for some crops, also for some food crops, such as corn for example.
Although traditional chemical fertilizers are often properly used by farmers, and can partly be absorbed by nature in case of an overdose, however, insecticides and pesticides contain elements that are not easily biodegradable. Through runoff, these molecules accumulate in groundwater and soils, thus destroying a large portion of the fauna essential to a living soil.
Beyond the environmental issue alone, the increasing soil contamination, and therefore of water by agrochemical molecules, becomes a public health concern. These indirect effects add to those related to the use of chemicals without protective equipment. Skin and eye diseases as well as deformities have multiplied in the area.
A solution: a natural insecticide
To address this issue, the CFB project technical team proposes beneficiaries to adopt an eco-responsible technique for crop treatment, more specifically for market gardening during the rainy season. This technique, introduced as a test during the 2017 agricultural season, helps the farmers rediscover the properties, known in Burkina Faso, of neem seeds and papaya leaves, a tree widespread in the country.
It is thus possible to obtain an effective insecticide made from local natural and renewable products. Sprayed on crops, it repels insects thanks to the neem odor and the aspect of leaves made slippery by the soap; the leaves are also strengthened with the papaya leaf juice.
Production Method for 10 liter (2.64 gal) treatment: Mix a decoction of 500 grams (17.63 oz) of neem seeds immersed in 8 liters (2.11 gal) of water, with 1 liter (0.26 gal) of papaya leaf juice and 10 grams (0.35 oz) of local soap dissolved into 1 liter (0.26 gal) of water.
