Previous studies have demonstrated these changes' economic, cultural, and political consequences. However, their effects on biodiversity have not been considered. The present study characterized the management carried out in three agroecosystems in the southeastern area of Mexico City and its possible relationship with agrobiodiversity. Objective: To evaluate the contribution of diversity, abundance, and composition of weeds as components of the sustainability of agroecosystems in Milpa Alta, Tláhuac, and Xochimilco municipalities. Methodology: 179 interviews were conducted with campesinos. Weeds sampling in 30 plots, recording the abundance and frequency of each species. These data were used to estimate different ecological parameters. Information on management practices was transformed to develop an “agroecosystem sustainability index.” A multivariate analysis was applied to compare weed attributes between agroecosystems and spaces and to detect possible relationships between the index and ecological parameters. Results: 156 species were recorded. The slope had the highest diversity, and ciénega had the lowest. More than half of the weeds were native, and the slope exhibited the highest number. The Importance Value indicated no dominant species on the slope, opposite to chinampa and ciénega. Species composition also differed between the three agroecosystems. Chinampa was impacted the most, whereas the slope was least affected. Implications: The displacement of traditional crops and agricultural practices and the incorporation of technological practices have modified the ecological attributes of weeds, like their abundance and composition. Conclusion: Starting from the argument that ecological attributes of weeds can be used as an indicator of sustainability, the slope resulted in the agroecosystem being most sustainable and should be used as a model to recover the agrobiodiversity of ciénegas and chinampas. ","PeriodicalId":23259,"journal":{"name":"Tropical and Subtropical Agroecosystems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the COVID-19 pandemic, an ample food supply was available to ensure the basic consumption of the population, prompting two questions: What resilient practices did farmers adopt to produce under conditions of high sanitary restriction, and what lessons did they derive to confront future crises? Objective: The article presents and collects the experiences of 59 small family farmers in Colombia in implementing good practices for economic and financial resilience and the lessons learned from the Covid-19 pandemic, constituting a new source of knowledge to understand human behaviors and actions in the face of adversity and the experiential learnings gained to act in future crisis scenarios. Methodology: To characterize the resilient practices of agricultural producers in the department of Norte de Santander, Colombia, amid the COVID-19 pandemic crisis, researchers conducted interviews with 59 smallholder farmers from 12 municipalities. The study encompassed 11 agricultural products and 6 animal products, ultimately identifying three overarching categories: economic resilience, financial resilience, and lessons learned. Main Results: The results indicate strategies for diversification of production, use of local resources, solidarity-based family work, short marketing chains and an economy of scarcity in family spending. Implications: These lessons can inform future policies and practices to better prepare for and respond to similar challenges. Conclusion: The study's findings provide valuable insights for policymakers and small farmers, emphasizing the importance of local resource utilization, community cooperation, and adaptive strategies to enhance resilience and sustain livelihoods during crises. ","PeriodicalId":23259,"journal":{"name":"Tropical and Subtropical Agroecosystems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141832721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salt-affected soils cause a significant portion of land to become unproductive yearly; its impact is severe in sub-Saharan African nations, especially the arid and semiarid lowlands, and the Rift Valley regions of Ethiopia are typically host to naturally salt-affected areas. Objective. To analyze the micronutrient content and map the micronutrient fertility status of agricultural salt-affected soils around Abaya and Chamo Lakes South Ethiopia Rift Valley. Methodology. A systematic sampling technique was employed to obtain 300 soil samples for the investigation from two depths (0-20 and 20-40cm), with a 600m sampling interval, of which 30 were used. The research data was analyzed using the application of standardized analytical procedures for soil data and descriptive and geostatistical techniques. Results. According to the study, there is low zinc available in the soil but an ample amount of iron, manganese, and copper. In addition, the study's findings revealed that, whereas the remaining micronutrient regional variability is found at long distances, available iron exhibited a regional variation in soil quality at small distances. Implications. The study suggests applying organic matter for better soil structure, water retention, and nutrient availability.Moreover, the results recommend that soils affected by salt might recover using various materials. Conclusions. In the study areas, zinc fertilizer may still be needed for an optimal yield even though the research area has low amounts of zinc fertilizer. The study concluded with management recommendations to minimize the adverse effects of very high micronutrient content on human health and plant growth.","PeriodicalId":23259,"journal":{"name":"Tropical and Subtropical Agroecosystems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141833149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: Total 100 farmers were selected using random sampling technique from 5 upazilas of Lalmonirhat district during July to December, 2022. Data were analyzed using SPSS 23.0 statistical package. Results: Results showed that most of the farmers (65%) at the northern part of Bangladesh were middle-aged, 41% of them completed secondary education, and their occupation was mainly agriculture (55%). About 37.78% of respondents supplied roadside grass as roughage to their livestock. Maximum number of respondents (60.24%) supplied hand mixed feed as a source of concentrate whereas 39.76% of respondents used commercial feed. 96% of farmers practiced artificial insemination to inseminate their cows and heifers while in goat nearly all respondent farmers (98.41%) practiced natural mating. Among the breeding companies, 41.41% farmers preferred semen from the Bangladesh Rural Advancement Committee (BRAC), followed by Advanced Chemical Industries (ACI) (30.30%), Government (Department of Livestock Services (DLS) (22.22%), and others (6.07%). About 41.76% respondents used 50% Sahiwal - 50% local genotype bull to breed the cows whereas 23.08% respondents used 100% Sahiwal, 18.68% used 75% Holstein Friesian-25% local, 5.49% used 100% Holstein Friesian, 3.30% used 50% Holstein Friesian-50% Local and only 3.30% used 87.5% Holstein Friesian-12.5% Local genotype bull semen, respectively. On the other hand, most of the farmers (98.41%) chosen Black Bengal breeding buck during breeding and remaining used crossbred (Black Bengal Goat- Jamunapari) to breed their does. The actual price of bull semen from Govt. (DLS) was 30 Bangladeshi Taka (BDT) on average for all the breeds whereas, the price ranged 110-200 BDT depending on cattle breeds and bull/bucks Identification (ID) in different private enterprises. Farmers had to pay on an average 181.18 BDT for DLS originated semen in addition to that BRAC Artificial Insemination (AI) workers took an average of 425.61 BDT from farmers to inseminate their cows.
