Integrated landscape approaches have been identified as key to addressing competing social, ecological, economic, and political contexts and needs in landscapes as a means to improve and preserve agrobiodiversity. Despite the consistent calls to integrate traditional and local knowledge and a range of stakeholders in the process of developing integrated landscape approaches, there continues to be a disconnect between international agreements, national policies, and local grassroots initiatives. This case study explores an approach to address such challenges through true transdisciplinary and multi-stakeholder research and outreach to develop solutions for integrated landscapes that value and include the experience and knowledge of local communities and farmers. Working collaboratively with small-scale agroforestry farmers in Southern Brazil who continue to use traditional agroecological practices to produce erva-mate (Ilex paraguariensis), our transdisciplinary team is working to collect oral histories, document local ecological knowledge, and support farmer-led initiatives to address a range of issues, including profitability, productivity, and legal restrictions on forest use. By leveraging the knowledge across our network, we are developing and testing models to optimize and scale-out agroforestry and silvopastoral systems based on our partners? traditional practices, while also supporting the implementation of approaches that expand forest cover, increase biodiversity, protect and improve ecosystem services, and diversify the agricultural landscape. In so doing, we are developing a strong evidence base that can begin to challenge current environmental policies and commonly held misconceptions that threaten the continuation of traditional agroforestry practices, while also offering locally adapted and realistic models that can be used to diversify the agricultural landscape in Southern Brazil.

To develop biodegradable food packaging, different biopolymer blend ratios of cassava starch (S) and soy protein isolate (P) (S100, S85P15, S70P30, S55P45, S40P60, and P100) were prepared by the extrusion method and then characterized. Before their application in foods, these blends must be characterized to enable the selection of the optimum materials for different packaging applications. For this purpose, the thermal and structural properties of the blends and possible interactions between the polymers were analyzed by thermogravimetric analysis (TG), dynamic mechanical analysis (DMA), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR) spectros- copy. The moisture and oil resistance (surface energy, water vapor permeability (WVP), moisture content and solubility, and oil permeability), mechanical properties (tensile and puncture strength), and transparency of the blends were also investigated. The addition of protein resulted in crosslinking between the starch and protein chains and increased the crystallinity, as observed by FTIR, XRD, and DMA. Consequently, the stiffness of S40P60 increased, presenting a 120 % higher elastic modulus, and the WVP decreased 25 % compared to S100, likely due to the crosslinking of the polymer chains promoted by the addition of protein. In contrast, the S70P30 blend had greater hydrophilicity, leading to 68 % increase in moisture content and WVP, respectively. The S40P60 blend presented 22 % higher water solubility than the other blends. The S85P15 blend exhibited higher dispersive energy ability, and consequently, higher permeability to oil. P100 was 19 % less transparent than the other samples. Concerning the studied blends, S40P60 presented a low water vapor and oil permeability and low dispersive energy, while also presenting low transparency. Therefore, the use of this blend should be considered for packaging for foods with high lipid contents MenosTo develop biodegradable food packaging, different biopolymer blend ratios of cassava starch (S) and soy protein isolate (P) (S100, S85P15, S70P30, S55P45, S40P60, and P100) were prepared by the extrusion method and then characterized.
