Land Suitability Analysis of Coffee (Coffea arabica), Pineapple (Ananas comosus) and Mango (Mangifera indica) for Sustainable Agriculture and Food Security in Burkina Faso, West Africa

/0 Comments/in /by

Land suitability assessment is critical for sustainable agricultural planning, especially in Burkina Faso’s Sudano-Sahelian zone, where soil deterioration and nutrient deficits limit perennial crop development. Pineapple, coffee, and mango are commercially attractive crops that have the potential to diversify rural livelihoods and increase food security. The objective of this study is to evaluate the land suitability for pineapple, coffee, and mango based on the soil physical and chemical properties in Saaba. A soil profile was conducted to determine the physical features, and soil samples were collected and examined to determine the chemical characteristics. Physical soil parameters, such as texture, rooting medium, and depth, showed high appropriateness (S1) for pineapple and mango. However, coffee was classified as not suitable (N) because to its shallow soil depth (<40 cm). Chemical characteristics indicated an appropriate pH (5.7-5.8). Exchangeable potassium (48.54-79.25 mg/kg) was consistently classed as highly suitable (S1) across all crops. However, available phosphorus levels were dangerously low (0.88-2.44 mg/kg), resulting in a “not suitable” (N) rating for all samples and crops. Organic matter differed significantly: Sample 1 (0.73% OM) was classed as non-suitable for all crops, whereas Samples 2 and 3 were moderately acceptable (S2) for pineapple and mango but only marginally appropriate (S3) for coffee. The primary limitations to land suitability for perennial crops in the study area are severe phosphorus deficiency and organic matter depletion. Although pH and potassium are favorable, sustainable production of pineapple, coffee, and mango requires interventions such as phosphorus fertilization and organic matter restoration. Pineapple and mango are more adaptable to current soil conditions, while coffee should be grown in areas with higher organic matter and robust soil management.

The Effect of Consumer Interest Level on the Implementation Level of Sustainable Agriculture in Green Vegetable Cultivation

/in /by

Green vegetables are one type of food that is very commonly consumed by the community to fulfill nutrients, vitamins, minerals, fiber and iron. The nutrients contained in green vegetables are needed to increase endurance and facilitate the body’s metabolic processes, so it is very related to public health. Vegetable products consumed must be ensured in a safe and hygienic condition, in this case requiring a good and correct cultivation process as stated in the recommendations of a sustainable agricultural system. The objectives in this study were to determine the level of consumer interest in green vegetable products, determine the level of application of sustainable agriculture in green vegetable cultivation and analyze the effect of the level of consumer interest on the level of application of sustainable agricultural systems in green vegetable cultivation. The research was conducted in August 2022 in Jati Agung District, South Lampung Regency on green vegetable farmers with 76 respondents. The research method used is descriptive quantitative with Parcial Least Square (PLS) statistical analysis assisted through SmartPLS software version 3.0. The results showed that the level of consumer interest in green vegetable products is in the low category, which means that vegetable products are no longer in great demand by the community, while the level of implementation of a sustainable agricultural system is in the high category, meaning that respondents have been able to implement good cultivation recommendations even though they are not maximized. The results of the analysis show that the level of consumer interest has a significant positive influence on the level of application of sustainable agricultural systems in vegetable cultivation, meaning that the better the level of consumer interest, the higher the application of sustainable green vegetable farming systems.
