China Title: Impact of digital economy on agricultural land use in sub-Saharan African countries Abstract: This study investigates the effects of digital economy (DE) on agricultural land use (ALU) in seven sub-Saharan African (SSA) countries, specifically from 2006 to 2022. Using a moderating mediation model on panel data, the work explores the extent to which the DE, as proxied by fixed telephone subscriptions, internet usage, and mobile penetration, influences the degree and intensity of ALU. The results indicate that ALU is often supported by DE, as technology will lay the groundwork for improved land management and agriculture. Results show that DE has a positive influence on ALU, with a more substantial effect being observed in countries such as Kenya and South Africa, where more developed digital infrastructure and governance are in place. In contrast, Uganda and Zambia exhibit lower impacts due to lower levels of digitalisation and governance barriers. The patent applications (PAs) and water management represent the positive mediators of the efficiency of land-use improvement. The study highlights the need for government-enabling policies and digital infrastructure so that the promise of digital technologies and their uptake for agricultural production in SSA is fully fulfilled. Whenever technology is integrated with an appropriate resource management policy, SSA societies have the potential to achieve sustainable agricultural development and food security.

The paper systematically analyses 63 peer-reviewed articles from 2013 to 2025, focusing on key optimisation techniques, including multi-criteria decision-making (MCDM), vehicle routing problems (VRP), and path planning problems (PPP). The findings highlight how logistics optimisation can reduce operational costs, improve resource utilisation, and enhance supply chain resilience. Additionally, the study identifies gaps in inbound logistics research and emphasises the need for further integration of digital technologies. Future research should focus on comprehensive, technology-driven solutions to improve adaptability and transparency in agricultural supply chains. Key findings reveal that optimised logistics models can lead to cost reductions of up to 58%, emissions savings of over 60%, and significant improvements in delivery time, field efficiency, and customer satisfaction.

China Title: An assessment of climate risks on the stability of biomass supply and biofuel production Abstract: Global warming has altered regional temperatures and precipitation, potentially leading to deviations from planned biofuel production and emission-reduction targets. This study revisits the market equilibrium of agricultural and biofuel production under climate risk, using updated IPCC projections. It employs a two-stage stochastic programming model to examine the overall effect of climate change on Taiwan's biofuel production. The results indicate that biofuel production depends on the level of climate impact and emission prices. In addition, total input use is generally between 2.79 and 4.72 million tonnes. The higher the gasoline price, the sooner the producer will exhaust its production capacity. While Taiwan could sustain biofuel production when gasoline and emission prices are high, a substantial land-use change would occur. Approximately 74 500-81 900 hectares of idle land will return to production. However, the increase in cropland supply may not lead to biofuel expansion, as it has a limited ability to offset emissions.

Using panel data from 13 major agricultural trading countries from 1990 to 2022, we applied cross-sectional dependence tests, fixed-effects panel regressions, and panel Granger causality analyses to examine the degree of interdependence and directionality in price movements. Our results reveal significant cross-sectional dependence, suggesting that global price shocks reverberate across the national markets. The panel regression estimates indicate a statistically significant and positive effect of international prices on domestic prices, with a stronger transmission observed in developed economies. Panel Granger causality tests confirm that global price indices significantly predict domestic price changes in most countries, although reverse causality is limited to large exporters, such as the United States, China, and Brazil. Robustness checks across sub-periods (1990-2005 vs. 2006-2022) and country groupings validate the stability and heterogeneity of the price transmission mechanisms. These findings underscore the increasingly integrated nature of food markets and the evolving dynamics of price volatility. The policy implications highlight the importance of multilateral coordination in food trade, differentiated policy tools tailored to country development levels, and the need for strategic buffering mechanisms to manage the growing global volatility in agricultural prices.
