“…Finally, agroecological practices contribute to improving the sustainability of agroecosystems while being based on various ecosystem services such as nutrient cycling, biological nitrogen fixation, natural regulation of pests, soil and water conservation, farming system resilience, biodiversity conservation, land degradation and carbon sequestration (Wezel et al, 2014). Common agroecological practices include reduced tillage, elimination of chemical synthesized fertilizers and pesticides, and use of biofertilizers, organic fertilization, drip irrigation and carbon addition to soil and constitute examples of activities associated with NBS in agricultural landscapes that address agricultural production (Wilhelm, 2021;Zeng et al, 2023). Comparison of simulated and measured (A) WSA (%) and (B) SOC and OC in AC1, AC2, cPOM and AC3 (tC/ha).…”

The water ecosystem food (WEF) nexus duly acknowledges the complex interdependencies among water, ecosystems, and food production, underscoring nature based solutions (NBS) as an efficacious strategy for navigating these interconnections. In this research, four different NBS (terraces, riparian forest, livestock management and agro ecological practices) were assessed in terms of their impact to WEF nexus. The Karst-SWAT and the one-dimensional integrated critical zone (1D-ICZ) models were used to simulate the impact of NBS on water quantity and quality as well as on soil ecosystem services of Koiliaris River Basin, which serves as an illustrative example of a basin that has experienced severe soil and biodiversity degradation. The Karst-SWAT model showed that a combination of NBS of terraces and riparian forest can reduce soil erosion and the sediment load by 97%. The 1D-ICZ model successfully simulated the soil-plant-water system and showed that agro ecological practices affect biomass production, carbon and nutrient sequestration, soil structure and geochemistry.

“…Suitable pathways may follow government schemes as seen for instance for cocoa agroforestry production in Ghana, West Africa or impact investments into sustainable agricultural landscapes (49,50). Second, lock-ins from cultural values, palatability, perceived health benefits, and social norms (51,52) are of critical consideration. For instance, olive oil production in Italy is a cultural heritage and likely much more difficult to substitute compared to soy production in Brazil, which is driven by large corporations rather than culture (53,54).…”

Global vegetable oil production is a crucial ingredient for food and household products but also a major source of greenhouse gas (GHG) emissions and other environmental externalities. A diversified supply may improve sustainability and resilience of profitable vegetable oil production globally. Here, we provide the first spatial assessment of the environmental and economic effects of major vegetable oil crops soybean, palm, rapeseed, sunflower, groundnut, and olive globally, based on new data from a meta-analysis and life cycle assessment. We show that diversified vegetable oil production through a highly productive oil tree cropCamellia oleiferacan reduce GHG emissions, water use, land use, and pesticide use by 14.0%, 4.9%, 7.3%, 9.3%, respectively and increase farmer income by 82.6%. When considering enabling conditions for technology and policy support, these benefits increase 1.3, 2.1, 1.8, 1.7, and 3.2 folds, respectively. Our results provide practical guidance where and how diversified oil crop production can advance a sustainable food system transformation and help to mitigate climate change.

A sound fallow program may potentially reduce food production and hence farmers' income in the short term but can help mitigate farmland pollution, improve food productivity, and enhance ecological protection in the long term. In China, degrading quality of arable land, soil pollution, and groundwater overexploitation require urgent implementation of suitable fallow schemes. We used existing spatial factors influencing the implementation of fallow schemes (including the delineated ecological protection red lines [EPRL], soil pollution, groundwater overexploitation, and arable land quality), and determined farmers' willingness to fallow to understand priority areas of fallow in China under multi‐scenario simulation. Results show that of all farmers willing to fallow, only 2.17% of farmers actively participated in a fallow scheme. Compared to other factors determining fallow implementation, our multi‐scenario simulation found that: (1) scales of the high fallow scheme exhibit a descending order of PES (priority to ecological security scenario, 20.58%) > MCL (minimum production capacity loss scenario, 19.52%) > PFW (priority to farmers' willingness scenario, 18.98%) > PFS (priority to food safety scenario, 15.30%) and that (2) the loss of grain production capacity in implementation of the high fallow scheme is PES (17.32%) > PFW (14.36%) > PFS (13.66%) > MCL (9.67%). We recommend that the implementation of the fallow program at a national level should consider farmers' willingness to participate in a fallow scheme, the loss of food production capacity in the short term, as well as the mitigation of arable land pollution, the improvement of ecological protection, and the safeguard of global food security in a long term.
