ABSTRACT
The rapid advancement of technology has significantly impacted the global way of life in a positive manner. However, it has also brought about negative consequences, particularly in the form of cybercrime. This article explores cybercrime, focusing specifically on cases of online data theft in Indonesia. Through a mixed research method, it can be identified that Indonesia is facing serious challenges related to cybersecurity, marked by a series of data leaks involving both government and private entities. The research also delves into the potential for online data theft in the policy transition from the National Identity Card (Kartu Tanda Penduduk or KTP) to the Digital Population Identity (Identitas Kependudukan Digital or IKD) in Indonesia. By detailing previous data leakage cases, this study indicates that the implementation of IKD in Indonesia needs to be reassessed. The conclusion drawn from the research is that efforts to enhance cybersecurity in Indonesia require concrete and collaborative measures, including the development of consistent regulations, the improvement of human resources in the field of cybersecurity, and better awareness among the public and government regarding the importance of protecting personal data. The study suggests further research to delve into the effectiveness of cybersecurity regulations in Indonesia and to understand the variables that influence public and governmental awareness regarding personal data protection.

Authors: Widadie Fanny , Wulandari Eliana , Lestari Retna Dewi
Published: January 2025

Purpose. This study explores the business models adopted by smallholder farmers in three different market channels – traditional, modern retail, and export markets. Furthermore, it evaluates and upgrades the smallholder business model in the traditional market to link and enhance inclusivity in high-value markets.
Methodology / approach. We use a qualitative approach by exploring three case studies of business models. The business models in this study elaborate how smallholders managing their business in terms of managing resources, meeting quality standards, and establishing partnership to link and serve the specific markets using business model canvas (BMC) analysis. To evaluate, make strategies and create a new business model to increase small farmers’ access to high-value markets, we use strength, weakness, opportunities, and threats (SWOT) analysis integrated with business model canvas analysis.
Results. The business model of smallholders in traditional markets lacks added value, economic activity, and quality standard compliance and has poor coordination with vertical (buyers) and horizontal (farmer group) actors in the value chains, as well as lack of support from the government compared to the business models in high-value markets (modern retail and export markets). Therefore, to link and improve the inclusivity of smallholders with high-value markets, their business model should be re-designed such as creating value propositions to be more concerned with producing vegetables with high-quality standards; conducting post-harvest handling activities and adopting food safety standards in their key activities; strengthening horizontal collaboration among farmers as key resources; building vertical coordination with suppliers in high-value markets and partnership with the government; adding market channels to sell to specialised wholesalers and exporters, and investing in the knowledge and facilities to produce vegetables of high-quality and safety standards.
Originality / scientific novelty. While many studies focus on specific markets, this study examines business models across three market channels. This study is among the first combine the BMC framework with SWOT analysis for smallholder business model evaluation and development. The result of this study bridges the gap between theory and practices in smallholder market inclusion, offering a novel framework for improvement business models of smallholders by integrates on economic, managerial and institutions perceptive.
Practical value / implications. This study is useful for policymakers to address the business constraints of small businesses when linking to high-value markets. Management implications for upgrading business models are also elaborated in this study for the inclusion of smallholders in high-value markets. This study also contributes to the literature on the inclusiveness of business models for smallholder farmers.

Impacts of climate change on agricultural value added in Ivory Coast
Authors: Kouakou Paul-Alfred Kouakou
Published: January 2025

Purpose. This study assesses the impact of climate change on agricultural value added through temperature and rainfall variability. The study uses annual data for 1992–2022.
Results. The results show that, in the short term, regular rainfall increases agricultural yields and boosts agricultural added value. However, even if temperature changes vary in smaller proportions than rainfall variability, they still lead to production deficits. Over the long term, the study predicts a positive relationship between temperature and agricultural value added. This prediction reveals the positive effects of the implications of economic policies in terms of intelligent agriculture. Over the same period, precipitation has a significant negative value. In fact, the onset of heavy rainfall affects crop productivity and yields, hence its negative impact on agricultural value added.
Scientific novelty. Previous studies on the impact of climate change on agricultural value added have mainly focused on the effects of rainfall and temperature variability on agricultural yields and the share of agricultural value added in the Ivory Coast’s GDP. However, very little empirical work has been done on the impacts of climate change on agricultural growth in Ivory Coast. This study fills this gap. It extends the existing literature on the causal relationship between climate change and agricultural development. Finally, the Vector Error Correction Model (VECM) is used to address this issue.
Practical value. The information generated will be useful to a number of organisations, including: research centres, universities, governments, governmental and non-governmental organisations, to better guide the development and implementation of resilience policies and strategies in a context of environmental crisis. Finally, by knowing the existing relationship between climate change and agricultural GDP, as well as the limitations of the resilience policies, the study provides the different ways to improve the capacity for creating agricultural wealth in the climate change issue. Research on this issue is crucial to inform policy makers in developing sustainable economic policies to achieve meaningful agricultural growth in the face of climate crises.

The processing of agricultural raw materials in improving human development in WAEMU countries
Authors: N’goran Koffi Célestin
Published: January 2025

Purpose. This study analyses the effects of the conversion of agricultural production on the well-being of the population of the countries of the West African Economic Monetary Union (WAEMU). It also analyses the link between the agricultural sector and the well-being of producers in the eight countries.
Results. The manufacturing agricultural added value representing the variable of interest of the study, has a positive and significant long-term coefficient. This result shows that the added value of agricultural raw material processing industries positively affects the human development index. An increase of one percentage point in the agricultural industrial sector in WAEMU countries leads to a long-term improvement in human development of 0.0017 percentage points. This is due to the investment effect that occurs in the long run, and trade openness has a positive impact on both long- and short-term welfare.
Scientific novelty. The originality of this study is focused on improving human development through the processing of agricultural products in WAEMU countries. The results indicate that the processing of agricultural products has a positive effect on human development in the long term but not significant in the short term. Similarly, the non-manufacturing sector contributes positively to the achievement of human development in the WAEMU zone in the long term.
Practical value. The study concludes by suggesting to the political decision-makers of the WAEMU countries to set up a partnership between producers of agricultural raw materials and processors that can lead to the establishment of a purchase contract. This could improve the well-being of agricultural producers. We propose to subsidise the development of processing enterprises in the union, which will encourage processors to increase production. In addition, a policy of import taxation is proposed to encourage domestic consumption of processed products. In order to provide agricultural and non-agricultural processors with a skilled workforce, governments should encourage education through productive public investment.

Monitoring and forecasting requires the collection of a large amount of data from various sources: data from weather stations, satellite data, video and photographic materials, data from special sensors installed in avalanche-prone areas, etc. Although most of the data can be obtained automatically, some of the data is collected manually. To speed up the process of collecting data collected manually, a mobile application was developed as part of this study. This mobile application allows you to collect data on clouds, precipitation, windy conditions, current temperature and snow height. The collected data is recorded in the local database of the application, which allows you to accumulate data for further data transfer. Data is transferred to the shared database through the API via REST requests to the database server via an Internet connection. Thus, the developed mobile application allows you to obtain the data required for forecasting and monitoring avalanche hazards in a more operational mode, which in turn allows you to improve the quality of monitoring and forecasting avalanche hazards.

В статье рассматривается многолетний анализ снежного покрова Восточно-Казахстанской области, который играет ключевую роль в гидрологических и климатических процессах региона. Исследование направлено на изучение пространственно-временных изменений продолжительности снежного покрова и оценку их влияния на водные ресурсы и лавинную опасность. Для проведения анализа использовались спутниковые данные MODIS с индексом NDSI, охватывающие зимние сезоны с 2000 по 2022 год. Обработка данных выполнялась с применением алгоритмов в облачной среде Google Earth Engine. Для верификации результатов привлекались данные наземных метеостанций региона.
Результаты исследования показали, что продолжительность снежного покрова существенно зависит от высоты местности. В высокогорных районах снежный покров остается стабильным на протяжении всего периода исследования, в то время как низменности демонстрируют значительные межгодовые колебания, связанные с глобальными изменениями климата. Это подтверждается сравнительным анализом данных спутникового мониторинга и наземных измерений. Полученные результаты имеют важное практическое значение и могут быть использованы для прогнозирования водных ресурсов и разработки эффективных мер по снижению лавинной опасности в регионе.

Изменение климата и связанные с ним экологические угрозы усиливают глобальный переход к возобновляемым источникам энергии (ВИЭ), что, в свою очередь, создает новые вызовы для энергосистем. Внедрение возобновляемых источников энергии и вывод из эксплуатации традиционных источников генерации снижает инерционную составляющую энергосистем, что может повлиять на их динамическую устойчивость. В статье предлагается развитие подхода для исследования влияния сниженной инерции на устойчивость параллельной работы Мангистауского энергоузла с ЕЭС Западного Казахстана. Основной акцент заключается в анализе электромеханических переходных процессов при высокой доле ВИЭ с учетом вывода синхронных генераторных блоков, в применении реальных параметров оборудования и первичной схемы энергосистемы, и в моделировании критически важных сценариев аварийных режимов для планирования устойчивой работы энергосистемы.
Выполнено пять сценариев для разных уровней инерции и двух исходных режимов сети. Симуляции осуществлялись с использованием PowerWorld Simulator 23, где рассматривались последствия трехфазного короткого замыкания с неуспешным повторным включением на линиях электропередачи 220 кВ. Результаты демонстрируют, что снижение инерции системы ведет к ухудшению динамической устойчивости, что может представлять серьезную угрозу для устойчивости энергосистем. Выводы исследования подчеркивают важность учета инерционности при планировании и интеграции ВИЭ в энергосистемы, а также необходимость в разработке новых принципов противоаварийной автоматики.

Published: January 2025

Abstract. Remote-sensing (RS)-based estimates of Arctic dust are oftentimes overestimated due to a failure in separating out the dust contribution from that of spatially homogeneous clouds or low-altitude cloud-like plumes. A variety of illustrations are given with a particular emphasis on questionable claims of using brightness temperature differences (BTDs) as a signature indicator of Arctic dust transported from mid-latitude deserts or generated by local Arctic sources. While there is little dispute about the presence of both Asian and local dust across the Arctic, the direct RS detectability of airborne dust, as ascribed to satellite (MODIS and AVHRR) measurements of significantly negative brightness temperature differences at 11 and 12 µm (BTD11–12), has been misrepresented in certain cases. While it is difficult to account for all examples of strongly negative BTD11–12 values in the Arctic, it is unlikely that airborne dust plays a significant role. One much more likely contributor would be water clouds in the Arctic inversion layer. The RS detectability of the impact of Arctic dust (notably due to Arctic dust from local sources) can, however, be of significance. Sustained dust deposition can substantially decrease (visible to shortwave IR) snow and ice reflectance albedo (pan-chromatic reflectance) and the signal measured by satellite sensors. Significantly negative BTD11–12 values would, however, only represent a limited area near the drainage basin sources according to our event-level case studies. The enhanced ice-nucleating particle (INP) role of local Arctic dust can, for example, induce significant changes in the properties of low-level mixed-phase clouds (cloud optical depth changes <∼ 1) that can readily be detected by active and passive RS instruments. It is critical that the distinction between the RS detectability of airborne Arctic dust versus the RS detectability of the impacts of that dust be understood if we are to appropriately parameterize, for example, the radiative forcing influence of dust in this climate-sensitive region.

Abstract. Reactive halogens catalytically destroy O3 and therefore affect (1) stratospheric O3 depletion and (2) the oxidative capacity of the troposphere. Reactive halogens also partition into the aerosol phase, but what governs halogen-aerosol partitioning is poorly constrained in models. In this work, we present global-scale measurements of non-sea-salt aerosol (nSSA) bromine and iodine taken during the NASA Atmospheric Tomography Mission (ATom). Using the Particle Analysis by Laser Mass Spectrometry instrument, we found that bromine and iodine are present in 8 %–26 % (interquartile range, IQR) and 12 %–44 % (IQR) of accumulation-mode nSSA, respectively. Despite being commonly found in nSSA, the concentrations of bromine and iodine in nSSA were low but potentially important, at 0.11–0.57 pmol mol−1 (IQR) and 0.04–0.24 pmol mol−1 (IQR), respectively. In the troposphere, we find two distinct sources of bromine and iodine for nSSA: (1) a primary source from biomass burning and (2) a pervasive secondary source. In the stratosphere, nSSA bromine and iodine concentrations increased with increasing O3 concentrations; however, higher concentrations of stratospheric nSSA bromine and iodine were found in organic-rich particles that originated in the troposphere. Finally, we compared our ATom nSSA iodine measurements to the global chemical transport model GEOS-Chem (Goddard Earth Observing System); nSSA bromine concentrations could not be compared because they were not tracked in the model. We found that the model compared well to our ATom nSSA iodine measurements in the background atmosphere but not in the marine boundary layer, biomass burning plumes, or stratosphere.

Abstract. Sunlight penetrates the bare-ice surface of glaciers and ice sheets, giving rise to the presence of a three-dimensional porous matrix of partially melted ice crystals known as the weathering crust. Surface meltwater slowly percolates through this weathering crust, which hosts active and diverse bacterial communities, until it reaches a supraglacial stream. Despite the potential implications of weathering crust dynamics for glacial melting and the export of carbon and nutrients to downstream ecosystems, its role in biogeochemical cycling remains unknown. Here, we use Fourier transform cyclotron resonance mass spectrometry to characterize dissolved organic matter (DOM) along a meltwater flow path in a hydrologically connected micro-catchment on the southern Greenland Ice Sheet. We find a decrease in the relative abundance of aromatic formulae from surface ice (24.9 ± 2.8 %) to weathering crust meltwater (3.5 ± 0.3 %) to supraglacial stream water (2.2 ± 0.2 %), pointing towards photodegradation of aromatic DOM during supraglacial meltwater transit. The relative abundance of aliphatic and peptide-like formulae in supraglacial stream DOM was lower (38.5 ± 4.0 %) than in weathering crust meltwater DOM (50.3 ± 2.4 %), likely as a result of microbial respiration of labile compounds within the weathering crust. Hence, we conclude that the weathering crust plays a thus far unexplored role in supraglacial biogeochemical cycling. In addition, we characterize water-extractable organic matter isolated from surface ice particulate matter, which was predominantly (61.6 ± 8.1 % relative abundance) comprised of aliphatic and peptide-like formulae, providing the first direct evidence of surface ice particulate matter as a potential source of biolabile DOM. As the spatial extent of bare-ice surfaces and the associated weathering crust photic zone is set to increase under a warming climate, our findings underscore the pressing need to further evaluate the role of the weathering crust in supraglacial biogeochemical processes. An understanding of weathering crust biogeochemical cycling is especially critical as climatic warming is predicted to lead to an increase in Arctic rainfall, consequently increasing the frequency of weathering crust degradation events, with unknown impacts on the export of supraglacial DOM to downstream ecosystems.

Abstract. Machine learning (ML) is transforming atmospheric chemistry, offering powerful tools to address challenges in tropospheric ozone research, a critical area for climate resilience and public health. As in adjacent fields, ML approaches complement existing research by learning patterns from ever-increasing volumes of atmospheric and environmental data relevant to ozone. We highlight the rapid progress made in the field since Phase 1 of the Tropospheric Ozone Assessment Report, focussing particularly on the most active areas of research, namely short-term ozone forecasting, emulation of atmospheric chemistry and the use of remote sensing for ozone estimation. Despite these advances, many challenges in the field remain, including the quality of data, benchmarks, and limited model generalisation and explainability. This review provides a comprehensive synthesis of recent advancements, highlights critical challenges, and proposes actionable pathways to further advance ML applications in ozone research. Achieving this potential will require close collaborations across atmospheric chemistry, ML and computational science, aimed at addressing key challenges such as the development of global benchmark datasets and robust, explainable models.

Abstract. Changes in climate have had major impacts on global vegetation during the Quaternary. However, variations in CO2 levels also play a role in shaping vegetation dynamics by influencing plant productivity and water-use efficiency, and consequently the relative competitive success of the C3 and C4 photosynthetic pathways. We use an eco-evolutionary optimality (EEO) based modelling approach to examine the impacts of climate fluctuations and CO2-induced alterations on gross primary production (GPP). We considered two contrasting periods, the Last Glacial Maximum (LGM, 21,000 years before present) and the mid-Holocene (MH, 6,000 years before present) and compared both to pre-industrial conditions (PI). The LGM, characterised by generally colder and drier climate, had a CO2 level close to the minimum for effective C3 plant operation. In contrast, the MH had warmer summers and increased monsoonal rainfall in the northern hemisphere, although with a CO2 level still below PI. We simulated vegetation primary production at the LGM and the MH compared to the PI baseline using a light-use efficiency model that simulates GPP coupled to an EEO model that simulates leaf area index (LAI) and C3/C4 competition. We found that low CO2 at the LGM was nearly as important as climate in reducing tree cover, increasing the abundance of C4 plants and lowering GPP. Global GPP in the MH was similar to the PI (although greater than the LGM), also reflecting CO2 constraints on plant growth despite the positive impacts of warmer and/or wetter climates experienced in the northern hemisphere and tropical regions. These results emphasise the importance of taking account of impacts of changing CO2 levels on plant growth to model ecosystem changes.
