It is a hazy day in December that scared Nur Izzatie, and she likes to weep at the pain and disturbance she is going through. Nur Izzatie came into her room and closed the door with a blast.

She thinks, ‘I will lose everything I have been working for a year. Without kelulut bees and bee hives, I will be out of business.’

Nur Izzatie just discovered that numerous kelulut bees had perished on the ground, and the bee hives were empty. Hundreds of bees emerge in front of the bee hive's entrance and begin to circle. In the absence of bees and honey, undoubtedly, there will be no business. Nur Izzatie had difficulty dealing with the problem, so fewer bees would die or flee away.

Published: August 2024

The Business Intelligence (BI) and Data Warehouse (DW) system deployed in the Nigerian National Petroleum Corporation should provide cooperate decision makers with real-time information to help them identify and understand key business factors to make the best decisions for the situation at any given time. The relentless collection of data from user interactions have introduced both a high level of complexity, as well as a great opportunity for businesses. In addition to connecting not just people, but also machines to the internet, and then collecting data from these machines via sensors would result in an unimaginable repository of data. This ever-increasing collection of data is known as Big Data. Integrating this with existing Business intelligence systems and deep analysis using Machine Learning algorithms, Big Data can give useful insights into business problems and perhaps even to make suggestions as to when and where future problems will occur (Predictive Analysis) so that problems can be avoided or at least mitigated. This paper targets at developing a system capable of optimizing a business intelligence using big data and machine learning approach. The design of a system to optimize the Business Intelligence System using Machine Learning and Big Data at NNPC was successfully carried out. The System was able to automatically analyze the sample report under NNPC permission to use and it generated expected predictive outputs which serves as a better guide to managers. When applying Deep Learning, one seeks to stack several independent neural network layers that, working together, produce better results than the already existing shallow structures.
Role of Local Government in Localizing SDG in Bangladesh
Authors: Islam Saiful
Published: August 2024

This study is unearthing the localizing process of SDG in Bangladesh in meeting the Sustainable Development Goals (SDGs) targets. Though nations bear the main responsibility for the SDGs, these goals specifically call for involvement from local authorities. Around 12 of the 17 SDGs require comprehensive strategies at the grassroots level to tackle interconnected issues like poverty, poor health, social challenges, and environmental degradation, with exceptions being Goals 9, 12, 13, 14, and 17. Bangladesh's constitution wisely allocates significant responsibilities for social and economic development, including the formulation and execution of plans concerning public services and economic progress, to the local government bodies, particularly the union parishad (UP), which serves as the primary interface with the community [Article 59(2)(c)(Constitution, 2004)]. Local Government Institutions in Bangladesh are positioned to have a significant influence on the localization of the SDGs, given their proximity to the most marginalized and frequently vulnerable rural communities, allowing for direct impact. Despite this potential, they have yet to make a substantial contribution to SDG localization, and with the deadline approaching, there is a pressing need to address this issue. This paper seeks to examine the obstacles encountered by local government in Bangladesh in their efforts to localize the SDGs, aiming to gain insight into the challenges hindering effective policy implementation.

In the volatile, uncertain, complex, and ambiguous (VUCA) business environment of today, online marketing has become crucial for connecting with customers and the community. Organisations leverage online marketing to retain and grow their customer base by fostering engagement and building strong community ties. This study explores how start-up leaders utilise online marketing systems to achieve these benefits. Targeting successful small retail business owners in India, the research involved semi-structured and face-to-face interviews, while other data sources include reviews of public documents, company websites, and social media sites. The findings reveal the strategies that start-ups use to boost sales through digital marketing. Four key themes emerged from data collection and analysis: (a) social media platforms and strategies; (b) online marketing strategies and challenges; (c) online content strategies; and (d) follow-up strategies. These findings expounded upon the digital marketing techniques employed by business organisers to increase sales, build strong customer relationships, and promote community development. The study recommended that start-ups should enhance the use of social media platforms, refining online content to better engage target audiences, address the challenges inherent in online marketing, and develop robust follow-up strategies to maintain customer relationships. The study highlights how these businesses would enhance brand recognition, drive progress, and maintain sustainability by utilising various communication networks to advance and promote products and services in the retail industry.

Plastic waste has become a significant problem of environmental pollution in recent decades. The nature of plastic waste is complicated to decompose; it has worsened the environmental situation, especially if it is not taken seriously immediately. One approach that can be taken to overcome this problem is to provide counseling to the public so that they do not dispose of plastic waste carelessly. The community service program is a forum for academics to participate and provide counseling about the management of plastic waste. The purpose of this community service program is to counsel the Panjangrejo community about how to manage plastic waste properly. This counseling program began with discussions with the Panjangrejo sub-district officials and related parties, then continued with planning the timing of the extension. Residents and community elements are fully involved, so this program can run smoothly. The counseling program was carried out in three villages, namely the villages of Semampir, Gunung Puyuh, and Krapyak Wetan, and this program was held at night from 20.00 WIB to 22.00 WIB. The outreach results showed that people's knowledge about the dangers of plastic waste and how to manage it could be significantly improved (p < 0.05). In general, this extension program successfully increased respondents' knowledge from "not knowing" to "knowing better" about the dangers and how to manage plastic waste.

The production of rice bran waste pellets was carried out in Gadingsari Village, Kapanewon Sanden, Bantul Regency, Special Region of Yogyakarta. The problem that occurs is that the high price of fish pellets can make it difficult for fish farmers. It is necessary to make fish pellets independently from rice bran waste using raw materials including rice bran, fish meal, corn flour, tapioca flour, vitamins, yeast, molasses or molasses, EM4, and water. The aim is to reduce production costs for fish cultivation by utilizing unused raw materials, such as rice bran. The method used is direct socialization and training. The steps for making fish pellets start from weighing the ingredients, making adhesive, mixing the ingredients, fermenting the ingredients, molding the fish pellets, ovening the fish pellets, and packaging the fish pellets. The resulting fish pellets contain 40% protein.

Climatic controls on metabolic constraints in the ocean
Authors: Mongwe Precious , Long Matthew , Ito Takamitsu , Deutsch Curtis , Santana-Falcón Yeray
Published: August 2024

Abstract. Observations and models indicate that climate warming is associated with the loss of dissolved oxygen from the ocean. Dissolved oxygen is a fundamental requirement for heterotrophic marine organisms (except marine mammals) and, since the basal metabolism of ectotherms increases with temperature, warming increases organisms' oxygen demands. Therefore, warming and deoxygenation pose a compound threat to marine ecosystems. In this study, we leverage an ecophysiological framework and a compilation of empirical trait data quantifying the temperature sensitivity and oxygen requirements of metabolic rates for a range of marine species (“ecotypes”). Using the Community Earth System Model Large Ensemble, we investigate how natural climate variability and anthropogenic forcing impact the ability of marine environments to support aerobic metabolisms on interannual to multi-decadal timescales. Warming and deoxygenation projected over the next several decades will yield a reduction in the volume of viable ocean habitats. We find that fluctuations in temperature and oxygen associated with natural variability are distinct from those associated with anthropogenic forcing in the upper ocean. Further, the joint temperature–oxygen anthropogenic signal emerges sooner than temperature and oxygen independently from natural variability. Our results demonstrate that anthropogenic perturbations underway in the ocean will strongly exceed those associated with the natural system; in many regions, organisms will be pushed closer to or beyond their physiological limits, leaving the ecosystem more vulnerable to extreme temperature–oxygen events.
Patterns of centennial to millennial Holocene climate variation in the North American mid-latitudes
Authors: Shuman Bryan N.
Published: August 2024

Abstract. Noise in Holocene paleoclimate reconstructions can hamper the detection of centennial to millennial climate variations and diagnoses of the dynamics involved. This paper uses multiple ensembles of reconstructions to separate signal and noise and determine what, if any, centennial to millennial variations influenced North America during the past 7000 years. To do so, ensembles of temperature and moisture reconstructions were compared across four different spatial scales: multi-continent, regional, sub-regional, and local. At each scale, two independent multi-record ensembles were compared to detect any centennial to millennial departures from the long Holocene trends, which correlate more than expected from random patterns. In all cases, the potential centennial to millennial variations had small magnitudes. However, at least two patterns of centennial to millennial variability appear evident. First, large-scale variations included a prominent Mid-Holocene anomaly from 5600–5000 yr BP that increased mean effective moisture and produced temperature anomalies of different signs in different regions. The changes shifted the north–south temperature gradient in mid-latitude North America with a pattern similar to that of the North Atlantic Oscillation (NAO). Second, correlated multi-century (∼ 350 years) variations produce a distinct spectral signature in temperature and hydroclimate records along the western Atlantic margin. Both patterns differ from random variations, but they express distinct spatiotemporal characteristics consistent with separate controlling dynamics.
Dynamics of CO2 and CH4 fluxes in Red Sea mangrove soils
Authors: Breavington Jessica Ashley Valerie , Steckbauer Alexandra , Fu Chuancheng , Ennasri Mongi , Duarte Carlos Manuel
Published: August 2024

Abstract. Red Sea mangroves have a lower carbon burial rate than the global average, whereby small greenhouse gas fluxes may offset a large proportion of carbon burial. Monthly soil core sampling was conducted across 2 years at two sites within a central Eastern Red Sea mangrove stand to examine carbon dioxide (CO2) and methane (CH4) fluxes under dry and inundated conditions. Fluxes were highly variable, characterized by a prevalence of low emissions punctuated by bursts of high emissions. At the landward site, average ± SE (median) flux from the soil-air interface was 3111 ± 929 (811) µmol CO2 m−2 d−1 and 1.68 ± 0.63 (0.26) µmol CH4 m−2 d−1 under light conditions, and 8657 ± 2269 (1615) µmol CO2 m−2 d−1 and 0.84 ± 0.79 (0.59) µmol CH4 m−2 d−1 under dark conditions. Average ± SE (median) sea-air fluxes were –55 ± 165 (-79) µmol CO2 m−2 d−1 and 0.12 ± 0.23 (0.08) µmol CH4 m−2 d−1 under light conditions, and 27 ± 48 (53) µmol CO2 m−2 d−1 and 0.16 ± 0.13 (0.09) µmol CH4 m−2 d−1 in dark conditions. The seaward site recorded higher CH4 flux, averaging 18.7 ± 8.18 (1.7) and 17.1 ± 4.55 (7.7) µmol CH4 m−2 d−1 in light and dark conditions. Mean fluxes offset 94.5 % of carbon burial, with a median of 4.9 % skewed by extreme variability. However, reported CO2 removal by total alkalinity emission from carbonate dissolution greatly exceeded both processes and drives the role of these ecosystems as intense CO2 sinks.

Abstract. Aim: Terracing is widely distributed in mountainous and hilly areas around the world and can be effective in inhibiting soil erosion, increasing soil moisture, improving soil quality and potentially having a positive impact on soil carbon pools. Methods: To understand the impact of agricultural activities and ecological restoration measures on changes in soil carbon pools in terraced areas, we set up an observation system in typical terraces on the Loess Plateau and soil samples were gathered from 0–100 cm depth in terraces (containing different crops and different ecological restoration vegetation) and slopes. Results: The results show that terracing can effectively increase soil organic carbon (SOC) content (7.7 g∙kg−1 in terraced cropland > 4.9 g∙kg−1 in sloping cropland). Changes in the organic carbon content of the terracing is mainly due to improvements in soil and water conservation capacity and agricultural activities, loss of soil organic carbon due to short-term abandonment and an increase in soil organic carbon due to replanting of fruit trees and crops. The choice of tree species in afforestation policies has also led to differences in soil organic carbon. Pinus tabuliformis Carr. has the highest SOC content (9.8 g∙kg−1). Conclusions: The SOC content in 0–100 cm of terraced fields planted with wheat was 1.5 times higher than that of sloping fields planted with wheat. Compared with sloping land, terrace construction significantly increased the SOC content of cultivated land, especially in the top soil layer (0–30 cm), and converting some sloping land into terraces would enhance the carbon sequestration capacity. This study has significant implications for agricultural management and ecological restoration in the terraced areas of the Loess Plateau and contributes to the development of rational policies for carbon sequestration on arable land in terraced areas.
Surprise floods: the role of our imagination in preparing for disasters
Authors: Ommer Joy , Neumann Jessica , Kalas Milan , Blackburn Sophie , Cloke Hannah L.
Published: August 2024

Abstract. What's the worst that could happen? After a flood has devastated communities, those affected, the news media, and the authorities often say that what happened was beyond our imagination. Imagination encompasses the picturing of a situation in our minds linked with the emotions that we connect to this situation. However, the role imagination actually plays in disasters remains unclear. In this regard, we analysed the responses of a survey that was disseminated in the 2021-flood-affected areas of Germany. Some respondents perceived that due to their lack of imagination regarding the flood, they did not take adequate action in advance. Limited or a lack of imagination could be linked to never having experienced a flood before, difficulties in interpreting forecasts and warnings, the perceived distance to waterbodies, and cognitive biases. Overall, the responses indicated the influence of imagination on risk perception. Based on these results, we recommend that future research should investigate the extent to which visual support can help forecast and warning communication to trigger the imagination of citizens in the short-term. From a long-term perspective, research should focus on how to cultivate imagination over time through participatory risk management, developing climate storylines, citizen weather observations, and the like.

P PENGARUH KATALIS ZEOLIT PADA LIMBAH PLASTIK POLYSTYRENE MENJADI BAHAN BAKAR MINYAK MENGGUNAKAN REAKTOR PIROLISIS
Authors: Kalsum Ummi , Herawati Netty
Published: August 2024

Sampah plastik yang terus meningkat jumlahnya menimbulkan masalah bagi lingkungan, penyebabnya tak lain sifat plastik yang tidak dapat diuraikan dalam tanah. Alternatif yang bisa membantu penanganan sampah plastik adalah proses daur ulang yang lebih menguntungkan salah satunya adalah dengan mengkonversi sampah plastik menjadi bahan bakar minyak sebagai sumber energi alternatif melalui pirolisis. Pirolisis merupakan salah satu bentuk proses daur ulang dengan mengubah plastik menjadi bahan bakar. Selain bermanfaat untuk mengurangi jumlah sampah plastik, pirolisis sampah plastik juga bermanfaat untuk menyediakan bahan bakar dengan nilai energi yang cukup tinggi. Penelitian ini bertujuan untuk mengetahui proses konversi limbah plastik menjadi bahan bakar minyak dengan mengetahui pengaruh % katalis zeolit terhadap sifat fisika dari spesifikasi bahan bakar minyak yang berbahan baku dari limbah plastik polystyrene berdasarkan metode American Standard Testing and Material (ASTM). Penelitian ini menggunakan proses catalytic cracking yaitu dengan variasi katalis zeolit dari 10%, 20%, 30%, 40% sampai 50% pada temperatur 420℃ selama 2 jam untuk mengetahui karakteristik sifat fisika dari minyak pirolisis yang dihasilkan seperti: densitas, viskositas, specific gravity, flash point dan water content. Semakin tinggi kadar katalis yang digunakan maka bahan bakar minyak yang dihasilkan akan semakin kental dan pekat, sehingga hasil terbaik berada pada persentase sebesar 10% dan sesuai spesifikasi bahan bakar minyak jenis solar 48.

El artículo expone los resultados del análisis de la dinámica del sistema socio-técnico de producción e innovación de carne aviar en Argentina. A partir de un marco analítico–conceptual convergente, con aportes de las trayectorias de estudios sociales de la tecnología y de la economía evolucionista neo-schumpeteriana orientada a sistemas complejos, el estudio se focaliza en analizar la evolución histórica del sistema. Para esto utiliza aportes de la Teoría del Actor Red (TAR) y del análisis estadístico de social network. Las conclusiones expresan cuestiones teóricas y políticas. En cuanto a las cuestiones teóricas, evidencia las posibilidades de convergencias entre los aportes de ambas trayectorias académicas del campo latinoamericano de Ciencia, Tecnología y Sociedad (CTS). Desde el punto de vista político, permite efectuar un análisis crítico sobre las redes tecno-económicas y sociopolíticas implícitas en el desarrollo del polo de producción de carne aviar en Argentina, sus limitaciones y desafíos para renovadas políticas de ciencia y tecnología en el sector.
1 Aspekte Gemeinsamer Agrarpolitik 2001
Authors: Manegold Dirk
Published: August 2024

Agricultural Markets at the Turn of 2001/2002The eight articles contained in this copy of the "Agrarwirtschaft" focus on - in the authors' minds - the most relevant developments affecting agricultural policy or markets over the last year. While the first contribution is on aspects of general agricultural policy the following ones refer to world, EU and German commodity markets together with more specific policy items.1 Agricultural PolicyThe agricultural policy discussion in Germany was dominated last year by several political changes proposed by the new Federal Minister of Consumer Protection, Food and Agriculture who came into office 12 January 2001. EU enlargement and WTO negotiations also attracted some attention but ranged behind. The change at the top of the German agricultural policy administration was made in reaction to the public's deep rooted dissatisfaction with the political handling of animal diseases (BSE, FMD) and former food scares. Political claims like "20 % organic farming within ten years", "quality instead of quantity" and "a turnaround in agriculture" caused much irritation among farmers. New food quality labels, stricter regulations for good husbandry (as e.g. an earlier end to hen battery cage systems in Germany, protection of animals during transport), however, pleased consumers.
Indikatoren einer nachhaltigen Landwirtschaft im Regionalisierten Agrar- und Umweltinformationssystem für die Bundesrepublik Deutschland (RAUMIS)

Indicators for a Sustainable Land Use in the Regionalised Agricultural and Environmental Information System for Germany(RAUMIS)According to the formulation of a political concept which centres on the principles of sustainable agricultural land use, agri-environmental aspects have gained an accretive importance within model based policy consultation. In this context, the following article illustrates the Regionalised Agricultural and Environmental Information System RAUMIS. It describes the state of development of the actual integration of agri-environmental indicators as well as analytical results and their applicatory suitability. The main intention of using indicators within RAUMIS is to achieve a differentiated illustration of environmental impacts of agricultural land use in the context of actual-state analysis and prospective simulations.
Die Berücksichtigung von Unsicherheit und Flexibilität in der Investitionsplanung - dargestellt am Beispiel einer Vertragsinvestition für Roggen
Authors: Mußhoff Oliver , Hirschauer Norbert
Published: August 2024

Investment decisions are, as a rule, characterized by uncertainty, irreversibility and flexibility. Simple net present value calculations will not account for these features. In many situations even flexible investment planning with decision trees, which represents the most advanced method of traditional investment appraisal, does not have the capacity to solve practical decision problems adequately. One handicap is a realistic and manageable representation of stochastic variables. It has long been known that stochastic simulation procedures offer a nearly unlimited capacity to represent distributions and stochastic processes. However, a standard simulation will not allow for the consideration of flexibility. The problem is that with a simple forward moving simulation of stochastic paths it is not clear at potential investment dates whether waiting or investing represents the optimal strategy. In this paper we show how stochastic simulation procedures can be integrated successfully into a backward recursive programming approach. The resulting modus operandi can be called "Bounded Recursive Stochastic Simulation" (BRSS). We use this efficient combination of simulation and dynamic programming to answer the question whether farmers should buy sales contracts which guarantee fixed prices for rye in the future. The results of the model affirm the importance of uncertainty and flexibility for investment decisions. They also show that the actual conditions offered by the wholesale buyer are not economically attractive for farmers, unless they are extremely risk averse. Thus, model results coincide with the empirical evidence that farmers do not enter these contracts.

Demand for quality-differentiated beef in Japan
Authors: Saghaian Sayed H. , Reed Michael R.
Published: August 2024

In this article, we apply a model of vertical product differentiation to the Japanese beef market. We theoretically derive a system of consumer demand functions for quality-differentiated beef in Japan. We choose a particular utility function which is nonlinear in the consumption of the quality-differentiated product and linear in the consumption of all other goods. We employ a seemingly unrelated econometric model to estimate Japanese consumer demand functions for four beef types from the four origins. The empirical results show Japanese consumers prefer domestically produced beef to imported US and Australian. We also find seventeen substitution and two complementary effects among the various origins.

Economies of Scale in der Produktion versus Diseconomies im Transport: Zum Strukturwandel im Molkereisektor
Authors: Boysen Ole , Schröder Carsten
Published: August 2024

In this article, we simulate structural change within the German dairy sector employing a sector-wide optimization model. As a result, we obtain cost minimizing structures of the dairy sector for various scenarios differentiated by time horizon and level of transportation cost. We demonstrate that the model is capable of explaining the current trend which is characterized by a decrease in the number of dairies while average capacity is increasing. However, this development is less pronounced if transportation cost rises relative to other costs.
Effects of decoupling on land use: an EU wide, regionally differentiated analysis
Authors: Britz Wolfgang , Heckelei Thomas , Pérez Ignacio
Published: August 2024

This paper presents a quantitative analysis of the impacts of the „Luxembourg Compromise” as compared to a continuation of Agenda 2000 to the year 2010. The employed new version of the CAPRI model allows us to represent the different member states’ implementations of the CAP reform and to reflect endogenous world market prices based upon a spatial global trade model. The specific contribution of the analysis is a detailed look at the impacts of national differences in the CAP implementation and regional production structures with respect to changes in land allocation. At EU level, cereal areas decrease by about 5% and oilseeds by about 3%. This is paralleled by increases in the set-aside acreage and extensive fodder production. However, significant differences at the regional level can be observed. They are caused mainly by differences in the shares of durum wheat and fodder maize.
Simulating the effects of decoupled transfer payments using the land use model ProLand
Authors: Weinmann Bernd , Schroers Jan Ole , Sheridan Patrick
Published: August 2024

This paper describes the bio-economic land use model ProLand and presents selected results for scenarios of coupled and fully decoupled Pillar One transfer payments under the European Union’s Common Agricultural Policy (CAP). The basic assumption for the model is that land users select the land use alternative from a set of agricultural and silvicultural land use systems which is expected to generate the highest possible land rent. The model is used to estimate effects of fully decoupled transfer payments on land use in a less favoured region in Hesse, Germany. The results confirm that the CAP Reform removes the distorting effects of coupled transfer payments. The extent and direction of land use changes are spatially variant. Overall, the CAP Reform will lead to increases of permanent grassland area at the cost of arable land. The total agricultural land rent generated in the region will grow substantially, mainly due to higher amounts of transfer payments.
