“…For example, double cropping has been used by corn (Zea mays L.), soybean (Glycine max L.), and wheat (Triticum spp. L.) growers in Brazil due to its high efficiency in land use and resource utilization (Elobeid et al, 2019). In Europe, an empirical analysis showed that increased diversification of land use and management in wheat fields in a Mediterranean climate can increase yield resiliency caused by climate change (Reidsma and Ewert, 2008).…”

Double-cropping strawberry (Fragaria × ananassa Duch.) and lettuce (Lactuca sativa L.) could be a sustainable alternative practice for diversified specialty crop growers. Plastic mulch is beneficial for strawberry and lettuce production with soil-biodegradable mulch (BDM) providing opportunities to reduce plastic waste generation and costs of mulch disposal. The objective of this study was to compare non-biodegradable plastic mulches and BDM to bare ground cultivation in a strawberry–lettuce double-cropping system in a Mediterranean climate. A split-plot randomized complete block design experiment with mulch treatment [non-biodegradable polyethylene (PE) film, “weedmat” (woven, PE-based), BDM, and bare ground control] as the main factor and double-cropping rotation scheme (rotation 1 or 2) as the split-plot factor was conducted between 2020 and 2021. Strawberry yield was overall greatest when mulched with BDM, PE, and weedmat compared to the bare ground control. Total soluble solids (TSS), pH, and total titratable acidity (TA) of strawberry differed due to harvest date, but only pH differed due to mulch treatment. For lettuce canopy cover, rotation 2 had greater canopy cover (86%) compared with rotation 1 (66%) 30 days after transplanting. Average head weight (0.4 kg) and head length and diameter (both 20 cm) did not differ due to mulch or rotation. Average soil temperatures under PE and BDM were ~1.5°C higher than under weedmat and 2.5°C higher than the bare ground control. Soil under weedmat had the highest moisture content, whereas the PE, BDM, and bare ground treatments had similar levels. PE, BDM, and weedmat provided equivalent weed suppression, whereas the bare ground control had the most weeds. BDM deterioration estimated as percent soil exposure (PSE) was greatest (59% PSE) by the end of the experiment, whereas PE had 18% PSE and weedmat had no deterioration. Results show that despite high levels of deterioration, BDM performs similarly to PE in terms of soil temperature and moisture modification, weed suppression, and promotion of crop growth and yield in a double-cropped system. Double-cropping strawberry and lettuce is a promising alternative for growers to diversify their crop type and with potential economic benefits by increasing mulch lifespan.

“…The concept of "indirect land-use change" (ILUC) is the most contested aspect within the land use emission category. It emerged in the discussion on biofuels when it was realized that new types of demand for agricultural products, beyond global food supply, would be partially responsible for expansion into new production areas (and thus for emissions associated with such expansion), even if the origin of specific products could be traced to low-emission areas (e.g., not linked to recent forest conversion) [79,80] . In practice, however, ILUC remains controversial as the attribution involves scales beyond the reach of individual producers or consumers and may need to shift to broader product categories.…”

Carbon Footprints

The urgent global reduction of greenhouse gas emissions depends on political commitments to common but differentiated responsibility. Carbon footprints as a metric of attributable emissions reflect individually determined contributions within, and aggregated national contributions between, countries. Footprints per unit product (e.g., of food, feed, fuel, or fiber) require a lifecycle analysis and support individual decisions on consumption and lifestyles. This perspective presents a framework for analysis that connects the various operationalizations and their use in informing consumer and policy decisions. Footprints show geographical variation and are changing as part of political-economic and social-ecological systems. Articulation of footprints may trigger further change. Carbon footprints partially correlate with water and biodiversity footprints as related ecological footprint concepts. The multifunctionality of land use, as a solution pathway, can be reflected in aggregated footprint metrics. Credible footprint metrics can contribute to change but only if political commitments and social-cultural values and responsibilities align.

“…However, the continued expansion of biofuels will not only exert high pressure on agricultural prices but also dramatically impact the environment and greenhouse gas emissions [59]. Using the life cycle theory, Meng et al [60] have studied the evaluation system of sustainability of biomass liquid fuels. However, this study has yet to include the impacts of land use changes on agricultural prices and greenhouse gas emissions.…”

To explore the potential of growing energy crops and then producing liquid fuels in marginal land in China, in this paper, the status quo of existing biomass resources and marginal land utilization in China have been first analyzed and the development process of biomass liquid fuels has then been reviewed. Through the investigation, we have found that alternative fuels such as bio-diesel, bio-based alcohols, ethers, and esters will be the current and future research focuses. Secondly, using ethyl levulinate (EL) as our research subject, we have explored the production capacity of growing energy crops in marginal land and their potential to prepare liquid fuels. Then, the carbon sequestration of energy crops, the carbon emissions of liquid fuels, and the influence of liquid fuels on land use changes have been deeply analyzed. This study has revealed that the potential of sweet sorghum, cassava, jatropha curcas, and switchgrass cultivation in China in producing is 75.76 million tonnes, 1.52 million tonnes, 4.57 million tonnes, and 5.16 million tonnes, respectively. Among these crops, sweet sorghum and switchgrass have a higher production capacity and are more suitable to be planted on marginal land and used to produce liquid fuels. The planting of these two crops has absorbed about a 111.11million tonnes and 7.57 million tonnes of carbon dioxide (CO2), respectively, presenting significant carbon sequestration and oxygen-producing effects. Finally, the problems in developing marginal land have been summarized. Furthermore, we have proposed policy recommendations for marginal land development, energy crop cultivation, and liquid fuel development suitable for Chinese conditions, hoping to provide essential data for China's land restoration and biomass liquid fuel development.
