Reliable, spatiotemporally explicit agricultural land-use data is essential for tracking progress and enabling policies such as subsidies and tax concessions. This study presents the <i>Farm Action Toolkit (FAcT)</i>, an AI-enabled, Earth Observation (EO)-based framework for long-term cropland and paddy monitoring (2002-2024), linking EO data to farmer benefit access and FYP implementation. FAcT delivers Bhutan's first national, field-scale cropland and paddy dataset, achieving 87-92% accuracy and [Formula: see text] values of 0.75--0.85 against government statistics. Between 2002 and 2024, cropland experienced a 22.5% net increase, with 50.3% gain and 27.8% loss with respect to the 2002 baseline. Of the cropland lost, 66% reverted to forest post-2018, aligning with 12th FYP conservation goals. Net primary productivity declined by 2%, while per-capita cropland area dropped by 16.5%, underscoring population pressure and land competition. In Paro District, approximately 30% of cultivated land verified using EO data was found to be active but missed policy benefits due to gaps in manual verification, revealing critical inclusion barriers. FAcT's co-development with national agencies ensured scientific rigor and institutional uptake. The open-source toolkit (https://zenodo.org/records/15621464) supports land-use decision-making, resilience planning, and sustainable agriculture in smallholder, high-elevation, and data-scarce contexts. Findings contribute to Sustainable Development Goals (SDGs) 2, 11, and 15, demonstrating how EO-based agricultural monitoring can inform policy interventions and impact tracking in mountainous regions.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44279-026-00498-3.</p>","PeriodicalId":520507,"journal":{"name":"Discover agriculture","volume":"4 1","pages":"31"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12855294/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146109489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CMD incidence and symptom severity increased significantly with field density and were higher in intercropping systems, whereas whiteflies thrived in cassava monocultures. Of the climatic parameters analyzed, the most significant correlation was found between temperature and CMD symptom severity which were negatively linked. Humidity and rainfall exerted moderate positive effects on disease levels. The southern areas, with relatively high relative humidity and generally abundant rainfall were found to be most affected by CMD with severe symptoms. The study also showed that local susceptible cassava varieties were more frequently cultivated in the different agroecological zones studied compare to improved cassava varieties that are known more tolerant or resistant to the disease. This may explain why CMD incidence was relatively high in almost all agroecological zones.

Following PRISMA guidelines, 598 records from three databases were initially identified: Scopus (43), PubMed (18), and Taylor & Francis (537). After duplicate removal and successive screening steps; title, abstract, and full-text review, a total of twelve (12) studies met the inclusion criteria and were retained for the final analysis.

Nine (9) of the papers reveal that balanced macronutrients (nitrogen, phosphorus, potassium) and soil amendments like biochar and organic fertilizers significantly enhance tomato sensory profiles by optimizing sugar-acid balance, aroma compound synthesis, and fruit firmness. Seven (7) studies found that sustainable practices, including reduced synthetic fertilizer use and improved microbial diversity, were shown to mitigate soil degradation while boosting nutrient cycling and water retention. Conversely, four papers found that soil contamination with heavy metals and poor management practices were linked to diminished sensory quality, including off-flavors and reduced sweetness. Soil health strongly affects tomato sensory quality. Organic amendments such as biochar and compost substantially enhance flavour, aroma, texture, and visual appeal.

The review highlights the importance of catchment-scale models in understanding the impact of land use on local ecosystems, particularly in relation to water quality, biodiversity, and soil services. By examining various international catchment-scale models, with an emphasis on the micro and macro disparities, the paper identifies key methodological lessons and future opportunities to enhance these frameworks for more effective policy design and environmental management. The review is structured around a conceptual framework that categorises models into environmental models, which focus on ecosystem dynamics, and physical models, which examine structural and material aspects of land use systems, as well as human dimensions, with a specific focus on reducing net emissions and improving land productivity. This relationship is described through a conceptual framework. The paper also emphasises the significance of spatial and temporal factors in these models, noting gaps in the literature limited integration of food production into catchment models, underrepresentation of localised/catchment-level modelling, data limitations, particularly lack of georeferenced micro-level data, inadequate incorporation of climate change scenarios and temporal variability, weak integration of biophysical, economic, and social factors, insufficient analysis of policy and governance impacts at catchment scale and lack of farm-specific, actionable recommendations. The research highlights the critical need for enhanced data accessibility, environmental model maintainability, standardised land use variable definitions, and improved georeferencing in land use modelling.

Despite numerous efforts aimed at formalizing seed markets, informal seed systems still dominate with 97% of smallholder farmers sourcing seeds of sorghum, common beans and groundnuts through farm-saved seed and local grain markets. Traders are deeply embedded in these local markets and are better positioned in shaping the seed demand, particularly among smallholders who buy grains as seeds from informal outlets. However, in most cases traders remain disconnected from formal breeding and seed dissemination efforts, subsequently leaving a gap between the development of improved varieties and their adoption by farmers. This scenario perpetuates the use of old varieties that are well known to traders, limiting potential benefits from genetic gains. In this study, we examine the factors that could influence traders' decisions to sell grains of improved varieties. Data from a structured survey of 976 traders in Tanzania is used. We find that traders with higher financial capacity, stable market access, and those having strong relationships with farmers through credit provision are more likely to sell grains of improved varieties. Similarly, we find positive associations with switching to improved varieties among traders facing business challenges, accessing information through channels other than social media, and traders selling grains as seeds at sowing. In contrast, traders engaged inthe sale of highly demanded varieties are less likely to switch to new and improved varieties. Therefore, to spur the uptake of improved varieties, strengthening trader-farmer linkages, integrating traders into structured procurement systems, and enhancing trader involvement in participatory variety selection to refine existing and preferred varieties without changing them altogether are recommended. Additionally, there is need to strengthen business modeling programs to make grain traders' businesses bankable, expand information sharing and facilitate access to credit enabling them to adequately offer technical support to thefarmers they source grains from.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44279-025-00413-2.</p>","PeriodicalId":520507,"journal":{"name":"Discover agriculture","volume":"3 1","pages":"241"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12602625/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145508577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Burkina Faso, efforts are underway to manage it sustainably using classical surveillance, including field monitoring and laboratory diagnosis. However, this method has significant limitations that make it difficult to address early management. The aim of this study was to provide recent epidemiological data on CMD, while highlighting the limitations of classical surveillance. Fields monitoring and laboratory diagnosis took 14 months for the 2020 survey and 6 months for the 2022 survey year. A total of 4,680 plants from 156 fields were assessed in 2020 and 3,810 plants from 127 fields in 2022. The overall mean incidences were 9.46% and 3.33% in 2020 and 2022, respectively. The highest incidences were found in the Centre-Ouest region (23.13%) in 2020 and in the Plateau-Central region (32.38%) in 2022. The Plateau-Central region was identified as a CMD new outbreak. In 2020 survey, <i>African cassava mosaic virus</i> (ACMV) rate was 93.95%, while <i>East African cassava mosaic virus</i> (EACMV) was 3.69%. In the 2022 survey, ACMV alone was detected in 75.95%, in double infection with EACMV in 16.46%, and triple infection with EACMV and <i>East African cassava mosaic Cameroon virus</i> (EACMCMV) in 5.06%. This study showed that classical surveillance is a robust method, but extremely time consuming to anticipate early management of CMD. Similarly, classical surveillance required significant financial resources for its implementation. Given these constraints, the implementation of participatory surveillance involving farmers, extension agents, breeders, plant protection services, and researchers could help in CMD management efforts.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44279-025-00386-2.</p>","PeriodicalId":520507,"journal":{"name":"Discover agriculture","volume":"3 1","pages":"197"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12504380/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145260457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biostimulants, such as amino acids, offer natural and stable solutions to improve yield, growth, and resistance to external factors. They achieve this by reducing the impact of abiotic stress and stimulating plant defence mechanisms. As biostimulants, amino acids' simplicity, cost-effectiveness, and environmental friendliness have garnered recognition whilst offering natural and stable solutions to improve crop yield and resistance to external factors. Mixtures containing multiple amino acids are commonly used in agriculture, but the effects of individual components within these mixtures are less understood. This review summarises current knowledge on the effects of the foliar application of the 20 most common naturally occurring amino acids. The similarities in observed effects, as well as proposed modes of action, have been discussed. Notably, distinct differences in the modes of action of these amino acids have been observed, with two key themes emerging: firstly, an enhancement in the rate of photosynthesis through the promotion of chlorophyll synthesis or improved electron transfer in Photosystem II (PSII); secondly, protection against oxidative stress, either by increasing antioxidant synthesis or directly acting as antioxidants. For some amino acids, the mode of action after foliar application is unclear, or the effects are minor, highlighting the need for further research into their specific mechanisms of action.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44279-025-00222-7.</p>","PeriodicalId":520507,"journal":{"name":"Discover agriculture","volume":"3 1","pages":"69"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075294/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A greenhouse experiment was conducted using various pea cultivars that were released in different decades [Century (1960), Trapper (1970), CDC Golden (2002), CDC Amarillo (2012), and CDC Spectrum (2016)] under monocropping and intercropping with wheat to evaluate the yield parameters and symbiotic N fixation capabilities of pea.

On the other hand, the companion wheat crop had a greater yield (29.8-69.9%) and seed N (31.1-65.5%) when intercropped with the newer pea cultivars. Intercropping enhanced N fixation (0.7-7.5%) in peas across cultivars; however, the older cultivars contributed more to the overall system's N fixation and N carry-over compared to the newer cultivars. While the harvest index, land equivalent ratio (LER), and N-based LER (LERN) of intercropped wheat were not significantly higher than mono-cropped wheat, the increased partial LER and LERN for wheat highlight intercropping benefits.
