Development cooperation in agriculture aims to contribute to the achieving of a large part of the Sustainable Development Goals (SDGs) of the UN 2030 Agenda, especially the first three, No Poverty (1), Zero Hunger (2), and Good Health and Well-being (3). Development cooperation in agriculture tries to help local communities to increase their awareness, participation, and skills about the management of land and environmental resources, in order to realize sustainable development. In this context, methods of participatory assessment of land suitability have been widely and successfully applied. The present research took place in the framework of a real development cooperation intervention in Nord Kivu (Democratic Republic of Congo) and aimed to implement a rapid participatory assessment of land suitability. In this context, where official and detailed data are not available, the study fostered the active involvement of local experts and used geographical information systems (GIS) to identify the most suitable crops to be supported in different zones of the study area. Toward this aim, the authors used a procedure based on the following steps: the identification of relevant land use types (LUTs), mapping capability factors, describing the responses of each LUT to the different capability factors, mapping potential land suitability for the LUTs, mapping accessibility, mapping land suitability for the LUTs. Resulting maps and tables were used to identify the most suitable areas for the different uses. Globally, forestry was the most suited use (99.6% of the study area is potentially highly suitable), followed by the cropping of manioc, sorghum, banana, oil palm, bean and cattle grazing in decreasing order (62.6% of the study area is potentially highly suitable for grazing). When accessibility is considered, forestry presents the largest decrease in the class of high potential suitability (−34.9% equal to a loss of 24,945.5 ha), while less adaptable uses, such as cattle grazing showed lower decreases in highly suitable class (−11.2%) and larger increases in scarcely suitable class (+9.5%). At a later stage, the comparison between computed suitability and actual land use helped with identifying the areas where forestry should be the only (or most) supported activity and the areas where to push integrated land uses. Our interpretation of the results allows us to recommend the adoption of agroforestry and intercropping as the main methodologies to integrate multiple aims such as the environmental conservation and the improvement of livelihoods.

“…Similarly, contamination levels higher than the EC limit for AFB1 were found in 61% of the contaminated maize samples, and for AFT in 53% of the same samples [7]. According to DE MARINIS et al [25], contamination rates higher than the limit ranging from 25% to 100% were measured for AFT in divers' varieties of maize from Haiti.…”

Aflatoxins are toxic metabolites present in various foods, especially when production and conservation do not respect good hygiene practices (GHP). In Ouagadougou, maize flour is produced and sold in different structures by actors who do not always respect GHP. Thus, it is necessary to regularly control the quality of these flours. So, this is carried out with the aim to assess the aflatoxin content of maize flours produced in the municipality of Ouagadougou. For this, twenty-eight (28) samples were collected from households, markets and supermarkets in the city of Ouagadougou. Thus, LC/MS/MS analysis was used to assess the aflatoxin content of the samples. The results obtained reveal the presence of total aflatoxins (AFT) in 78.57% of samples analyzed with levels ranging from 0.89 to 64.25 µg/kg. The prevalence of different types of aflatoxins were 57.14% for aflatoxin B1 (AFB1), 46.43% for aflatoxin B2 (AFB2), 42.86% for aflatoxin G1 (AFG1) and 4.6% for aflatoxin G2 (AFG2). The results also show that 80% and 60% of market samples, 70% and 30% of household samples and 37.5% and 25% of supermarket samples do not comply with European Commission standards for AFT and AFB1 respectively. For all the samples, 60.71% and 42.86% of the samples are compliant according to the limits established by the European Commission (EC) respectively for AFB1 and AFT. Regarding the results obtained, producers and processors must be supervised and trained in GHP for the production of better-quality flours.

“…All these different factors are potential causes of chronic food shortages encountered in Africa and, in particular, in the Democratic Republic of Congo (DRC) by the fact that they affect most plants of agronomic and economic interest by decreasing accordingly their values. The produces crop yields could which accentuated by the gradual loss of soil fertility, which is added to it, thus worsening the low purchasing power of farmers [7]. All these problems require an adequate and lasting solution to obtain the expected return.…”

The aim of the present study was to study the effects of gamma radiation (Cs137) on the local variety of maize (Zea mays L.) usually cultivated at KENGE for possible track of its improvement. The approach consisted of irradiating the corn seeds at the doses ranging from 0 to 300 Gy at intervals of 100 each using the CONSERVATOME LISA I irradiator. The irradiated seeds were sown on a plot of 176.40 m2 of surface area according to a device in completely random blocks. In the field, some cultural precautions for consequent yield have been taken (weeding, ridging at the same time as weeding, mulching, and watering). Different cultivation parameters were determined such as germination rate, crown diameter, plant size and number of leaves / maize plant from one part and, from another part, the length of the cobs, the ear diameter, number of kernels/ear, 100 kernel weights and yield per plot. From the results obtained it turned out that the dose of 100 Gy with average values such as 67% for the germination rate, 220.80 cm for the length of the plants, 1505 seeds per plant ear and 327.25 g per 100 seeds behaved well in relation to the witness and the irradiated persons. The dose of 300 Gy gave values far lower than those of 100 Gy (19%, 67.66 cm, 713 and 90.13 g). From these analyzes, it is possible to recommend an in-depth study in the improvement of local corn with the LD50 of 169.33 Gy.
