Soil bacteria and fungi play key roles in the functioning of terrestrial ecosystems, yet our understanding their responses to climate change lags significantly behind that other organisms. This gap is particularly true for drylands, which occupy ∼41% Earth´s surface, because no global, systematic assessments joint diversity soil have been conducted these environments date. Here we present results from a study across 80 dryland sites all continents, except Antarctica, assess how changes...
Abstract Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These “fertile islands” are major drivers of dryland ecosystem structure functioning, yet we lack an integrated understanding the factors controlling magnitude variability at global scale. We conducted a standardized field survey across 236 drylands from five continents. At each site, measured composition, diversity cover perennial plants. Fertile island...
Abstract. Soil indicators may be used for assessing both land suitability restoration and the effectiveness of strategies in restoring ecosystem functioning services. In this review paper, several soil indicators, which can to assess ecological dryland ecosystems at different spatial temporal scales, are discussed. The selected represent viewpoints pedology, ecology, hydrology, management. Two overall outcomes stem from review. (i) success projects relies on a proper understanding their...
During the last decades, pastoralist, and agropastoralist populations of world’s drylands have become exceedingly vulnerable to regional global changes. Specifically, exacerbated stressors imposed on these adversely affected their food security status, causing humanitarian emergencies catastrophes. Of stressors, climate variability change, land-use management practices, dynamics human demography are a special importance. These factors affect all four pillars security, namely, availability,...
Hyperarid, arid, semiarid, and dry subhumid areas cover approximately 41% of the global land area. The human population in drylands, currently estimated at 2.7 billion, faces limited access to sufficient, affordable, nutritious food. We discuss interlinkages among water security, environmental energy economic health food security governance, how they affect drylands. Reliable adequate supply, prevention contamination, increase potential for ample food, fodder, fiber production. Protecting...
ABSTRACT Winter cover cropping plays an important role in conservation farming. In the Midwest region of USA, strips planted with Austrian winter peas [AWP ( Pisum sativum L.)], radishes [RAD Raphanus sativus and a mixed both cultivars (MIX) were compared during spring season to determine their impact on soil quality at 0–5 5–10 cm depths. The treatments RAD, AWP, MIX had highest, intermediate, lowest bulk density impacts (1·67, 1·52, 1·50 Mg m −3 , respectively). An opposite trend was...
This study reviews the potential use of biochar as soil amendment in afforestation, reforestation, agroforestry, fruit tree orchards, and bio-energy plantations. Implementing this practice could sequester large amounts carbon (C) over long-term, potentially offsetting anthropogenic emissions dioxide, mitigating climate change. On a global scale, between 2 109.2 Pg biochar-C 1.75 billion ha degraded deforested lands agroforestry systems. An additional considerable amount be sequestered...
This essay addresses climate change and its main causes over the last three decades. Between 1992–2021, global emissions of greenhouse gases (GHGs) have risen continually. Specifically, major socioeconomic sectors – including (1) energy, (2) industry, (3) land-use/land-use change/agriculture, (4) transportation, (5) building/construction, (6) waste treatment/disposal emitted enormous amounts GHGs. 1992–2019, combined annual GHG by 53% from 32.6 to 49.8 Gt CO2 equivalent (CO2e). The...
