“…The application of agroforestry systems can have a large effect, especially in terms of conservation. Besides being beneficial in conservation, the application of agroforestry can prevent land erosion and degradation, reduce the impact of climate change and increase food productivity [20]. The second: mixed cropping patterns, minimum tillage, planting of ground cover, management of organic matter, permanent vegetation and application of agroforestry covered 38.79%.…”

Awareness of the dangers posed by the use of synthetic chemicals in farming attracts attention. The development of organic agriculture requires a suitable location. However, sometimes, suitable land is very limited. This study aims to select the site for the development of organic agriculture, as well as to function in overcoming the existence of critical land, especially in the Upstream of Air Bengkulu Watershed, Bengkulu. The research method carried out is by compiling a Map of Conservation Activity Plan (CAP) based on a model developed by the then Ministry of Environment and Forestry. Maps used for input to CAP are EHL (Erosion Hazard Level), Soil Depth, Slope, Population Pressure, and the Recommended Landuse. From the CAP Map, the sites that are estimated to be used for organic farming development locations will be obtained. Results show that the sites for CAP to support organic farming is divided, broadly, into 2 categories: (1) mixed cultivation, minimum tillage, planting of ground cover, management of organic matter and application of agroforestry covers 9.32% in Semidang Lagan and Karang Tinggi District, and (2) mixed cropping, minimum tillage, ground cover planting, organic matter management, permanent vegetation and application of agroforestry covers 38.79% in Taba Penanjung District, Bajak Dua, Jambu and Rindu Hati Village. While 51.89% of the study area in Taba Penanjung District should be used for protected area.

“…Seed access depended largely on seed exchanges among farmers or purchased from informal markets. Since yam diversity is high in DRC (Magwé-Tindo et al, 2018), farmers were also acquiring seeds from forest environments, a practice referred to as ennoblement elsewhere (Scarcelli et al, 2006;Chikwendu and Okezie, 2014;Agre et al, 2021;Adejumobi et al, 2023). In addition to poor farming practices and informal seed system, farmers lacked sufficient knowledge of tuber storage techniques and value addition, leading to high post-harvest losses.…”

Yam (Dioscorea spp.) is a key tuber crop in sub-Saharan Africa (SSA) with huge potential for poverty alleviation, food sovereignty, and nutrition security. Exploiting its full potential requires that factors holding it down are understood and mitigated. This study, conducted between May and July 2022 and 2023, assessed yam farming practices, varietal preferences, and land suitability in the Eastern Democratic Republic of Congo (DRC). We interviewed 765 smallholder farmers within four agro-ecological zones (AEZ) to assess the sociocultural, agronomic, varietal, and biophysical factors affecting yam production. Land suitability analyses were conducted using the Analytic Hierarchy Process (AHP) to identify areas suitable to extensive yam production and to cluster environments that could optimize yam varietal selection and testing. Results showed that yam is mainly cultivated by women in eastern DRC (70%). The seed delivery system is informal, relying primarily on farmer-saved seeds and farmer-seed exchanges (74.9%). Soil depletion (68.3%), limited access to high-quality seeds (54.5%), youth disengagement in yam value chain (50.3%), insect pests (17.9%), and short tuber shelf-life (65.8%) were, respectively, the main ecological, agronomic, sociocultural, biological, and tuber quality factors hindering yam production in eastern DRC. However, the perceived importance of most factors significantly varied with farmer gender and age categories. A multitude of varietal traits was used to assess yam varieties in eastern DRC, of which the tuber taste (59%) was the most valued trait regardless of gender and age categories, though it had highest scores among middle-aged adult women. Land suitability analyses discriminated five clusters; the most significant part of the region falling under suitable (27%), highly suitable (24%), and very highly suitable classes (37%). We further discussed how breeding initiatives for delivering yam varieties, suiting local producers’ and end-users’ needs, could unlock the crop’s potential for enhancing food security and wealth creation in eastern DRC. The land suitability map from this study is a valuable decision-making tool in defining priority areas for extensive yam production and varietal selection and testing. This study provided valuable insights on factors affecting yam production and suggested yam breeding as a backbone of a holistic approach seeking to address challenges faced in unlocking the potential for yam production in eastern DRC.

“…These principal components are linear combinations of the original variables and are ordered by the amount of variance they explain. Mathematically, PCA seeks to find the eigenvalues and eigenvectors of the covariance matrix of the original data, or equivalently, of the correlation matrix when the data are standardized [14][15][16] .…”

This study presents a novel framework This study proposes a new framework for evaluating the performance of distribution networks using a comprehensive approach. This method combines Principal Component Analysis (PCA) for extracting key performance indicators, Improved Analytic Hierarchy Process (IAHP) for determining objective weights of these indicators, and CRITIC method for determining subjective weights. Then, aggregate weights are used to calculate the comprehensive performance score of each part of the distribution network. On the premise of reducing computing resources, K-means clustering analysis is applied to classify the status of distribution network projects, providing data reference for project maintenance and repair. Finally, a case study and corresponding analysis of the evaluation results were presented, providing detailed insights into the practical application of the proposed framework. The limitations of current research and future research approaches were also discussed. The results indicate that the designed strategy performs well in terms of accuracy and computational convenience, and has potential application prospects
