Conventional farming practices can lead to soil degradation and a decline in productivity. Regenerative agriculture (RA) is purported by advocates as solution these issues that focuses on health carbon sequestration. The fundamental principles of RA are keep the covered, minimise disturbance, preserve living roots year round, increase species diversity, integrate livestock, limit or eliminate use synthetic compounds (such herbicides fertilisers). overall objectives rejuvenate land provide environmental, economic, social benefits wider community. Despite RA, vast majority growers reluctant adopt due lack empirical evidence claimed profitability. We examined reported mechanisms associated with against available scientific data. literature suggests agricultural such minimum tillage, residue retention, cover cropping improve carbon, crop yield, certain climatic zones types. Excessive chemicals biodiversity loss ecosystem degradation. Combining livestock agroforestry same landscape several co-benefits. However, vary among different agroecosystems may not necessarily be applicable across multiple agroecological regions.

Experimental impacts of grazing on grassland biodiversity and function are explained by aridity

Nature Communications, Год журнала: 2023, Номер 14(1)

Grazing by domestic herbivores is the most widespread land use on planet, and also a major global change driver in grasslands. Yet, experimental evidence long-term impacts of livestock grazing biodiversity function largely lacking. Here, we report results from network 10 sites paired grazed ungrazed grasslands across an aridity gradient, including some largest remaining native planet. We show that partly explains responses multifunctionality to grazing. greatly reduced steppes with higher aridity, while had no effects relatively lower aridity. Moreover, found further changed capacity above- below-ground explain multifunctionality. Thus, plant diversity was positively correlated excluded livestock, soil Together, our cross-site experiment reveals depend levels, more arid experiencing negative ecosystem highlight fundamental importance conserving for protecting

Plant root mechanisms and their effects on carbon and nutrient accumulation in desert ecosystems under changes in land use and climate

New Phytologist, Год журнала: 2024, Номер 242(3), С. 916 - 934

Опубликована: Март 14, 2024

Summary Deserts represent key carbon reservoirs, yet as these systems are threatened this has implications for biodiversity and climate change. This review focuses on how changes affect desert ecosystems, particularly plant root their impact mineral nutrient stocks. Desert plants have diverse architectures shaped by water acquisition strategies, affecting biomass overall Climate change can disrupt communities, with droughts impacting both shallow deep‐rooted groundwater levels fluctuate. Vegetation management practices, like grazing, significantly influence soil composition, microorganisms, biomass, Shallow‐rooted susceptible to human interference. To safeguard understanding architecture deep layers is crucial. Implementing strategic practices such reducing grazing pressure, maintaining moderate harvesting levels, adopting fertilization help preserve plant–soil systems. Employing socio‐ecological approaches community restoration enhances retention, limits expansion, reduces CO 2 emissions. underscores the importance of investigating belowground processes role in shaping landscapes, emphasizing urgent need a comprehensive ecosystems.

Dryland microbiomes reveal community adaptations to desertification and climate change

The ISME Journal, Год журнала: 2024, Номер 18(1)

Опубликована: Янв. 1, 2024

Abstract Drylands account for 45% of the Earth’s land area, supporting ~40% global population. These regions support some most extreme environments on Earth, characterized by temperatures, low and variable rainfall, soil fertility. In these biomes, microorganisms provide vital ecosystem services have evolved distinctive adaptation strategies to endure flourish in extreme. However, dryland microbiomes they are under threat due intensifying desertification climate change. this review, we a synthesis our current understanding microbial life drylands, emphasizing remarkable diversity adaptations communities. We then discuss anthropogenic threats, including influence change outline knowledge gaps. Finally, propose research priorities address those gaps safeguard sustainability fragile biomes.
