Food security is threatened by the combined pressures of increasing populations and climate change. Agricultural land vulnerable to overexploitation environmental Within this review, we identify role multiple cropping systems as an adaptation method towards Intercropping, relay or simultaneous cultivation two more crops, agroforestry, incorporation trees on at least 10% agricultural land, provides alternative practice which can provide many advantages over industrial sole cropping. Examples from these are given indicate how increased yield, stability, ecosystem services societal benefits when adopted. We also discuss instances where may be maladaptive desired not achieved. Finally, highlight important considerations constraints limiting adoption alternate modelling approaches used reduce uncertainty altering systems. This review challenges traditional concept increase crop yields whilst maintaining sustainability. Future research should aimed overcoming revolutionise global production.

Abstract International initiatives set ambitious targets for ecological restoration, which is considered a promising greenhouse gas mitigation strategy. Here, we conduct meta-analysis to quantify the impacts of restoration on emissions using dataset compiled from 253 articles. Our findings reveal that forest and grassland increase CH 4 uptake by 90.0% 30.8%, respectively, mainly due changes in soil properties. Conversely, wetland increases 544.4%, primarily attributable elevated water table depth. Forest have no significant effect N 2 O emissions, while reduces 68.6%. Wetland enhances net CO uptake, transition sources sinks takes approximately years following restoration. The ecosystem exchange restored forests decreases with age, about 3-5 afforestation reforestation sites, 6-13 clear-cutting post-fire sites. Overall, forest, decrease global warming potentials 327.7%, 157.7% 62.0% compared their paired control ecosystems, respectively. suggest afforestation, reforestation, rewetting drained wetlands, restoring degraded grasslands through grazing exclusion, reducing intensity, or converting croplands can effectively mitigate emissions.

The increasing emission of greenhouse gases such as CO2, CH4, and N2O from the soil has become a growing concern globally. To address this issue, biochar emerged an environmentally friendly amendment that can affect gas permeability reduce emissions. biochar-soil-plant system exhibits complicated interaction promotes plant productivity root elongation, further impacting objective paper is to provide comprehensive review effects on consequently in vegetated soil. begins by discussing basic characteristics its impact microstructure. It then explores both non-vegetated mechanisms through which influences are explained terms modified aeration, water holding capacity, adsorption, pH, available nutrients, activity microbes enzymes. role plants biochar-amended also analysed comparing group with non-vegetation group. includes discussion various methods used measure permeability, steady-state transient methods, well measurement techniques, chamber micrometeorological methods. Finally, future research directions proposed highlight corresponding roots biochar-induced variation emission.

Traditional agroforestry practices have economic, social, and environmental benefits to sustain human ecological systems. The demand for short-term economic benefit has derived from the traditional towards monoculture cash crop production in tropics. This study aimed assess greenhouse gas emission reduction capacity of systems concerning biomass soil carbon stocks districts Amhara Region, Ethiopia. From three practices, namely, multistory, woodlots, parkland, 300 smallholder farmers' farms were randomly selected carry out vegetation inventory 180 litter sampling. samples taken depths 0-20 cm, 20-40 40-60 cm. all woody plants was estimated using already developed allometric equations. mean total sink multistory is 40.7 ton ha−1 which significantly (p < 0.001) higher than woodlot, 20.8 ha−1, parkland 5.4 ha−1. ecosystem (biomass plus soil) 199.5 134.4 108.0 Soil organic accounted 72-88, 83-88, 92-98% stored respectively. revealed that could contribute sinks soils making it one nature-based solutions climate change mitigation. reduces emissions hence enhances mitigation adaptation roles existing land uses.

Abstract Atmospheric nitrous oxide (N 2 O) is a potent greenhouse gas, with long atmospheric residence time and global warming potential 273 times higher than CO . N O emissions are mainly produced from soils influenced by biotic abiotic factors that can be substantially altered anthropogenic activities, such as land uses, especially when unmanaged natural ecosystems replaced croplands or other uses. In this study, we evaluated the spatial variability of (maize, soybean, wheat, sugar cane crops), paired grasslands forests they across wide environmental gradient in Argentina, identified key drivers governing using structural equation modeling. We conducted on‐farm field measurements over years at nine different sites, including (mean rainfall 679 to 1090 mm year −1 mean temperatures 13.8°C 21.3°C), diverse plant species life forms, ecosystems, Semiarid Chaco Northwest Argentina Pampas Southeast. On average, agricultural systems emitted more twice (+120%), had soil water content (+9%), (+3%), nitrate (+19%) but lower ammonium (−33%) ecosystems. found use was main driver directly affecting NO 3 − contents both croplands. Urgent management practices aimed reducing needed mitigate their contributions climate change.

Agroforestry systems play important roles in carbon (C) sequestration western Canada. However, the effect of agroforestry system type and their component land-uses (forested area cropland) on soil organic C (SOC) stability is poorly understood. We studied SOC surface soils from two (shelterbelt hedgerow system) A 61-day laboratory incubation was used to assess biological stability, compared thermal measured during ramped combustion. The shelterbelt had a lower than as indicated by higher cumulative respiration loss incubation. Cumulative forested 1.63 1.57 times that cropland, indicating former. Thermal indicators, CO2-T50 (the temperature at which half CO2 produced), DSC-T50 exothermic energy released) ROI (return investment) were influenced interactive effects land-use, while TG-T50 mass lost) Ed (energy density) land-use land-use. Hedgerow cropland (higher TG-T50) area, there no difference among areas system. conclude planting trees agricultural land form alters stabilities, may have more stable system, thus, maintaining enhance promote climate change mitigation.

Abstract Enhancing our understanding of carbon (C) stock in diverse horticulture and fruit-based agroforestry systems has potential to provide farmers with supplementary advantages terms poverty alleviation livelihood development which can significantly benefit C market initiatives like UN-REDD (reducing emissions from deforestation forest degradation). Therefore, the current study aimed assess biomass accumulation, storage economic efficacy seven agro-ecosystems, namely guava-based agri-horticulture system (AHS), mango-AHS, guava- pure orchard (PO), mango-PO, Indian gooseberry -PO, teak boundary plantation (TBP) annual cropping (ACS) under two different landscape positions viz ., upland lowland semi-arid region Vindhyan ranges. The result indicated that mango-AHS accumulated ( p < 0.05) higher (26.01 t ha −1 ) vegetation density (13.01 whereas, soil (35.23 ), litter (0.64 total (46.63 was maximum mango-PO closely followed by mango-AHS. guava-PO exhibited sequestration (2.11 yr CO 2 abatement (7.76 rate compared other credit generation 129.76 US$ year . However, most lucrative providing net returns 4835.48 5.87 benefit–cost ratio. credits help getting an additional income; however, impact low (1.16–6.80%) when weighed against overall systems. Overall, concluded should adopt systems, especially establish mutually beneficial relationships between mitigation climate change stability. Graphical
