Summary: The research reveals that agricultural commodity prices have a positive impact on inflation, but under external uncertainty shocks, the rise in agricultural commodity prices is not always the primary driver of inflation. Inflation levels have both positive and negative impacts on agricultural commodity prices, suggesting that inflation can influence the supply and demand in agricultural commodity markets. These findings support the derived hypothesis that the interaction mechanism plays a role in the relationship between agricultural commodity prices and inflation.

Summary: The aim of this paper is to examine the impact of the COVID-19 pandemic on world energy commodity prices and their interactions with world food commodity prices. Based on data series analysis, it is evident that the pandemic caused a severe energy price shock which clearly had a negative impact on global economic growth, but the scale of this impact differs depending on the type of economic sector and countries' net export positions in energy and food trade.

Summary: The increasing financialization of energy and commodity markets presents tradeoffs for investors and consumers, with the long-term study showing bidirectional causality between oil and agricultural commodity prices. Surprisingly, both agricultural commodity prices and oil prices remained immune to shocks during the COVID-19 pandemic.

Summary: Ensuring the stability of supply and prices of agricultural products is crucial for people's wellbeing and social development. However, the outbreak of COVID-19 has led to significant contradictions between supply and demand in the agricultural market, resulting in sharp fluctuations in prices. The study finds that the COVID-19 pandemic has caused an average increase of 105.02% in retail prices of agricultural products in Chengdu, with the most significant impact on livestock and poultry, fruits and vegetables, and aquatic products. The supply side is more affected than the demand side, especially in areas with a relatively small primary industry and fast industrialization. In the short term, government policies to suppress prices do not restrain all agricultural prices.

Summary: We use dynamic time warping, a non-parametric pattern recognition method, to study the interlinkages between major energy and agricultural commodity prices. Cluster analysis is conducted to group commodity prices based on their behavioral likeness, resulting in two clusters: one containing crude oil and six major agricultural commodities, and the other containing coal and natural gas prices. The lead-lag associations between oil and crop prices change frequently, with oil prices generally lagging crop prices, but occasionally leading them.

Summary: An efficient machine learning-based framework is proposed for crop price prediction to assist farmers in estimating profit and loss in advance. The framework consists of four functional blocks: crop yield prediction, determination of supply, demand prediction, and crop price prediction. Various time series-based algorithms are utilized to forecast crop yield, while the supply is determined using predicted yield, residue, and import values. The demand is predicted solely based on the year, and crop price is predicted using different approaches including time series, statistical methods, and machine learning techniques. The decision tree regressor is identified as the best model for predicting crop price in this work, showing the superiority of the proposed framework over existing approaches.

Summary: This paper conducts a systematic review of the primary methodological approaches used to assess the influence of policies on the dissemination of agricultural innovations. The evaluation is divided into two clusters, focusing on the effects of policies on innovation adoption and yields/profitability. The majority of studies do not incorporate the evaluation of economic, social, and environmental aspects together, suggesting a need for increased interest in sustainability impact.

Summary: In this study, we contribute to the understanding of the agri-food market by exploring its efficiency and the role of the local Hurst exponent in predicting its trend. The analysis of the time series data for different agri-commodities reveals that mean reversion is more probable and occurs faster during anti-persistent periods. Therefore, we conclude that the Hurst exponent can help anticipate the future trend and range of expected prices in this market.

Summary: The study presents a comprehensive modelling framework to quantify the response of agricultural commodity prices to potential determinants, utilizing various types of autoregressive models. Results indicate that market fundamentals and macroeconomic developments have predictive power for commodity prices, which also react strongly to changes in international competitiveness, as measured by real exchange rate fluctuations.

Summary: Commodity price fluctuations have significant impacts on macroeconomics, industrial chain competition, and industry sustainable development. By using bibliometrics, this study traced the development of research on commodity prices and identified four main research hotspots: factors influencing commodity prices, impact on the macroeconomy, commodity price forecasting, and the financialization of commodities.

Summary: Microalgae have great potential as fourth generation biofuel feedstock, but the cost of production and biomass harvest are major obstacles. Using filamentous fungi to culture targeted algae can mitigate environmental impacts. Co-cultivation of microalgae with fungi using wastewater has shown feasibility for biofuel production. This article aims to discuss synergistic approaches, culture protocols, harvesting procedures, and potential biotechnological applications. Algal-fungal consortia can digest cellulosic biomass, potentially reducing operating costs and making biofuel production economically feasible.

Summary: In this systematic review, cross-commodity purchase task studies with human participants were examined. The findings revealed that tobacco and nicotine products were the most frequently assessed drug category. The most consistent economic relationships observed were the substitution of traditional cigarettes by e-cigarettes and e-liquid, and both legal and illegal cannabis for other drugs. The implications of these results in terms of treatment and harm reduction were discussed, and recommendations for future research were provided.

Summary: This study finds that movements of an undervalued U.S. dollar have a statistically significant negative impact on commodity prices, while movements of an overvalued U.S. dollar do not show an effect on commodity prices. This finding may be attributed to the expectation that an undervalued strengthening U.S. dollar continues to appreciate.

Summary: The study summarized the latest developments in Iran in the production of biodiesel from microalgae and fish waste, and evaluated the biodiesel potential from these two sources in Bushehr province. The results showed an increase in research on biodiesel production in Iran in the past decade, and estimated a total revenue of approximately $118.8 million from aquatic microalgae and fish waste in Bushehr province.

Summary: Increased investment in clean electricity and rising carbon costs are likely to lead to higher electricity prices, with a negative impact on employment in the most electricity-intensive sectors. This impact will be unevenly distributed based on the uneven distribution of these sectors across countries and regions.
