Climate change and variability impacts on grazing herds: Insights from a system dynamics approach for semi‐arid Australian rangelands por Godde, Cécile M., Dizyee, Kanar, Ash, Andrew, Thornton, Philip K., Sloat, Lindsey L., Roura, Eugeni, Henderson, Benjamin B., Herrero, Mario

“…While intensification strategies and favourable climates increased long‐term herd sizes, they also resulted in larger reductions in animal numbers during droughts and raised total enteric methane emissions. In the face of future climate trends, the grazing sector will need to increase its adaptability. …”

Synthesis of agricultural land system change in China over the past 40 years por Sun, Z., You, L., Müller, D.

“…For example, while the spatial concentration of crops and intensification of agriculture may have positive effects on the agricultural productivity necessary to meet increasing food demand, they also have caused the loss of biodiversity, depletion of water resources, soil exhaustion, surface and groundwater pollution, and increased carbon emissions (Kleijn et al., 2008; Matson, Parton, Power, & Swift, 1997; Searchinger et al., 2008; Tilman, Balzer, Hill, & Befort, 2011). …”

Market analysis for cultured proteins in low- and lower-middle income countries. por Herrick, T., Gannon, S., Kreis, Katharine, Zobrist, S., Harner-Jay, Claudia, Goldstein, J., Mason, S., Olander, L., Pérez, N., Ringler, Claudia, Shindell, D., Parker, M. E.

“…In addition, meeting this growing demand for animal-source foods will require rapid increases in livestock production, which has significant environmental impacts, requiring considerable land, water, chemical, and energy inputs.10,17,18 Global food production is responsible for roughly one-quarter of all greenhouse gas emissions, most of which (up to 80%) are related to livestock.20,21 Livestock production is also a contributor to water pollution, deforestation, land degradation, overfishing, and antimicrobial resistance.20,22,23 Given these challenges, this report aims to assess the market for potentially more sustainable alternative proteins and their potential for use in LMIC settings. …”
