“…According to the result defined in Figure 5b, the western and southern parts of the Jejeba watershed were highly and moderately suitable, whereas the northeastern parts were not suitable for oil palm tree cultivation, respectively. According to Moisa et al, (2022c), agricultural land nearest to road access was more suitable than others.…”

Ethiopia is investing in Oil Palm cultivation to minimize palm oil imports from other countries. Our aim was to analyze the potential land suitability for oil palm tree cultivation by using geospatial technology with an analytical hierarchy process (AHP) in the Jejeba watershed, Western Ethiopia. Ten parameters such as, land use land cover (LULC), land surface temperature (LST), agro-ecological zone (AEZ), slope, rainfall, soil types, soil texture, soil drainage, soil depth and road were aggregated and reclassified according to their suitability to evaluate potential land for oil palm cultivation in the study. In the presnt study, ArcGIS 10.3, ERDAS 2015, and ArcSWAT software were used. Results show that about 36.7 km2 (1.3%) was highly suitable for palm oil cultivation. Consiquentially,1780.5 km2 (64.8%) was moderately suitable for oil palm cultivation whereas, about 25.2 km2 (0.9%) of the study area was not suitable for oil palm cultivation. The southeastern part was highly suitable, whereas some eastern and northern parts of the study area were not suitable for oil palm cultivation. Therefore, government and non-governmental organizations should raise awareness among local communities to support oil palm cultivation in the study area. Further studies should be carried out, especially on the importance of soil PH, aspect, and proximity to markets should be investigated to understand the most suitable areas for Oil Palm cultivation in the western parts of Ethiopia.

An Evaluation of Possible Sugarcane Plantations Expansion Areas in Lamongan, East Java, Indonesia

et al. 2023

View full text Add to dashboard Cite

Sugar is a significant commodity for Indonesia because the need for sugar reaches 7 million tons. Meanwhile, imports from Thailand, Australia, and Brazil were approximately 5.54 million tons in 2020. Sugarcane and sugar production in East Java province is also supported by Lamongan Regency. Therefore, this study aims to evaluate the possible sugarcane plantation expansion areas in Lamongan. The evaluation process carried out in this study was an analysis of land suitability using the analytic network process (ANP) and land availability using an overlay analysis of several policy maps. Three parameters with the highest weight of the ANP were soil drainage (0.181), cation exchange capacity and base saturation (0.134), and rainfall (0.133). The total possible area for sugarcane plantations expansion in Lamongan was 32,552.37 ha and the largest class was Possible Area 2 (65.67%). The three sub-districts with the highest possible areas include Solokuro, Ngimbang, and Mantup. We recommend that the government and stakeholders extend the area allocated to sugarcane plantations in Lamongan because the possible expansion areas are still more than 30 ha, while in the 2011–2031 spatial plan they were only 8927 ha. Expansion plans must take into consideration other uses such as residence, industry, food crops, and protected areas.

“…Aquaculture is growing rapidly as a global food-producing sector and continues to flourish day by day [1][2][3][4]. It has been introduced in various regions of developing nations, including Africa and Asia, to provide rural communities with the chance to improve their quality of life and find a way out of poverty [5] by having a family income [6,7]. Fish meal represents 50% to 70% of the total material in fish feed [8].…”

Aquaculture is growing rapidly as a food-producing sector and in recent years fishmeal prices have climbed more than two-fold on a global scale. This review of previous studies was performed to contribute to the extant literature on the aquaculture sector to aid cost reduction of aquafeeds by identifying substitute proteins that can replace fishmeal. The review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) using the SCOPUS and WOS (Web of Science), DOAJ (Directory of Open Access Journals), Academia, and PubMed Central databases. A total of 59 articles were included in the synthesis after screening for duplicates and articles that did not conform to the criteria. Results have shown that the 100% replacement of fishmeal with blood meal (BM) did not affect the growth of fish, nor did the 75% to 100% combination of poultry-by-product (PBM), feather meal (FEM), and BM. Moreover, a 10% replacement of fishmeal using seaweed (Gracilaria arcuata) had no adverse effect on the feed efficiency and growth performance of tilapia. Similarly, a 50% replacement of fishmeal using black soldier fly (Hermetia illucens), and a 25% replacement using soybean (Glycine max) also showed better results for fish growth. Our review shows that alternative protein can replace fishmeal in the aquaculture sector and reduce the cost of aquafeeds since alternative proteins are much cheaper than the usual fishmeal. Adoption of these alternative protein sources hinges on financial support, start-up incentives for companies, and ongoing studies on waste-to-feed production, which the government can also support.
