Summary: Cereals-soybean intercropping has not been extensively studied, but comparing different intercropping practices with monocropping practices in Indonesia's rainfed areas showed significant yield advantages and economic benefits. Intercropping of rice-maize, rice-soybean, and maize-soybean resulted in higher yields, gross margins, and lower production costs compared to monocropping of rice, maize, or soybean. The potential for small farmers to increase yields and profits through intercropping in rainfed areas with a wet climate is substantial.

Summary: This study examines the impact of mechanization in land preparation (MLP) on irrigation water productivity (IWP) and identifies the factors influencing IWP. The findings indicate that adopting MLP significantly improves IWP. The determinant of higher IWP is whether farmers adopt MLP, rather than the channel they use to access farm machines. The effects of MLP adoption on IWP increase consistently across different quantiles.

Summary: This study establishes an evaluation framework of water use efficiency (WUE) coupling crop cultivation, commutation and consumption processes, and assesses the impact of virtual water flow on provincial irrigation water use efficiency in China. The results show that virtual water flow is conducive to water resource conservation and irrigation WUE improvement when judged by the indicator of water productivity per unit of output (IWP), but the result is just the opposite when judged by another indicator of irrigation efficiency (IE). The evaluation framework proposed in this study can inspire research on agricultural water assessment, management, and regulation combining the physical and virtual water.

Summary: Urban agriculture is seen as a sustainable feature of cities, providing economic, social, and environmental benefits. However, it is unclear how these benefits may compete or reinforce each other. This study uses an integrated modelling framework to analyze the characteristics of urban agriculture in different settings, applying proxy measures for economic, social, and environmental benefits. The results show that the optimal farming area and agricultural practices depend on the objectives pursued, with a preference for commercial urban agriculture for economic objectives and gardening urban agriculture for maximizing participation in the food system. In different locations, the model selects different forms of urban agriculture based on the specific objectives and assumptions.

Summary: Urban Agriculture (UA) is a widespread practice of food production within cities. The economic viability of UA depends on factors such as land and labor costs. This study analyzes these costs and calculates the margin and benefit-cost ratio for different UA scenarios in Adelaide, Australia and Kathmandu Valley, Nepal. The results show that high-value crops have the potential to make UA economically viable in Adelaide, but low-value crop scenarios are less likely to succeed in both locations. Land cost is identified as the primary driver of UA cost, while labor cost is a critical difference between the two cities, affecting the economic viability in Adelaide where the wage rate is high. To improve economic viability, governments and planners should consider providing subsidised land and labor arrangements. Home food gardens with access to available land and labor as spare time activities may represent the best way to produce food in cities without exceeding market costs.
