Agroecological approaches to sustainable development

Frontiers in Sustainable Food Systems, Год журнала: 2024, Номер 8

Опубликована: Ноя. 21, 2024

Agroecology has emerged as a fundamental paradigm for developing innovative solutions to major global concerns such food security, biodiversity loss, and climate change. The core subject of conservation emphasizes agroecology’s role in the preservation native species, pollinators, beneficial creatures through practices agroforestry, cover crops, decreased chemical inputs. Agroecological principles polyculture, crop diversity, integrated pest control help improve security by increasing stability nutrition. encourages carbon sequestration, soil health, greenhouse gas reductions, resulting climate-resilient farming systems. literature review revealed that no article thoroughly discusses all critical hitting challenges, change, single study can be addressed using agroecological principles. This attempts make connection between numerous challenges may solved techniques order facilitate sustainable growth while protecting environment. examines benefits incorporating methodologies into agriculture, with an emphasis on agroecosystem resilience, improving socioeconomic circumstances smallholder farmers, rural livelihoods, local communities, contributing change mitigation. It provides complete concepts their advantages, making it excellent guide policymakers, academics, practitioners who is working build resilient system. emerges light hope, boosting agricultural output also environment, ultimate goal achieving harmonious cohabitation mankind natural world.

Knowing the lay of the land: changes to land use and cover and landscape pattern in village tank cascade systems of Sri Lanka

Frontiers in Environmental Science, Год журнала: 2024, Номер 12

Опубликована: Июнь 24, 2024

Social-ecological systems (SESs) possess a great diversity of land use and cover (LULC) types with unique assemblages biodiversity ecosystem services. However, LULC changes due to landscape fragmentation are emerging as major threats the system productivity SESs around world. This study examined extent patterns in Village Tank Cascade Systems (VTCSs) Sri Lanka using satellite imagery GIS techniques between 1994 2021. Multispectral Landsat images (5 TM 8 OLI/TIRS) obtained from Google Earth Engine were classified machine learning algorithms. Overall accuracies 85.9% (1994) 88.6% (2021). The change matrix spatial pattern metrics used examine dynamics over VTCS landscapes. results revealed that forest, which is dominant class covering 73.7% total area was reduced by 206,725 ha transformation into agricultural (70.43%) scrub (24.33%) lands Over this time has gradually changed forest land-dominated landscape, showing significant negative correlation ( p < 0.001; R 2 > 0.868), particularly southeastern region. Landscape analysed based on eight calculated at both levels FRAGSTATS analysis software. At level, structure became more dispersed complex shape. Heterogeneity noted have increased weakening connectivity, whereas process had accelerated. dominance patches decreased, isolation increased, connectivity shape complexity leading loss fragmented habitats. number within aggregated performance indicators show VTCSs experienced gradual environmental sustainability. Assessment along can help monitor impacts determine ecological integrity. Thus, provides scientific guidance for restoration degraded effectively improve productivity.

Perspective Chapter: Redesigning Agroecological Practices for Enhanced Resource Use Efficiency in Agroecosystems

IntechOpen eBooks, Год журнала: 2025, Номер unknown

Опубликована: Март 3, 2025

The projected population of 9.1 billion in 2050 will necessitate a rise food production to accommodate an extra burden the human population. Consequently, it is imperative discuss innovative agricultural methods that have potential produce greater quantity while being environmentally friendly. In this chapter, we summarized pros and cons based on diversification following agroecological practices. current system poorly integrated with other activities processes (pesticide herbicide spray, bio-fertilizers, selection crop rotation, allelopathy) found be notorious for its wasteful use resources, which has adverse effects environment, biodiversity, economy. Quantitative analysis suggested integrate world’s chain sustainability agroecosystem improving carbon-to-nitrogen (C:N) ratio, soil properties, water, nutrient cycling. Redesigning practices (legume-based mulching, no/zero tillage, split fertilization, advanced irrigation practices, biological pest control measure, organic fertilization) synergized approach, leads matter recycling, soil-borne insect-pest pathogenic resistance, adaptability, net farm productivity. Therefore, redesigning inevitable increase resource efficiency within agroecosystems. This chapter invaluable those working academia, government, private sector promote sustainability.

Response of soil general and specific functions following loss of microbial diversity: A review

Soil Security, Год журнала: 2024, Номер 15, С. 100151 - 100151

Although an alarming rate of global biodiversity loss is occurring, the effects belowground microbial diversity on soil functioning still remain uncertain and debated across numbers experiments data. In this context, we synthesize evaluate impacts ecosystem from published literatures, elaborate probable mechanisms different response in terms general specific functions. The results showed that decreases both (e.g. pollutant degradation, methane metabolism, pathogen control) functions C N mineralization, respiration, biomass production), indicating functional redundancy may be overestimated, even for processes drive link between are influenced by environmental factors nutrient condition, pollution stress, moisture content). However, high stability crucial explaining maintenance function under scenario declining, which involves process genotypic/phenotypic traits effects. summary, our review has implications improved understanding regarding relationship general/specific functions, with suggestions future research provided.

Smallholder agriculture in African dryland agroecosystems has limited impact on trophic group composition, but affects arthropod provision of ecosystem services

Agricultural intensification is a major driver of biodiversity loss, but the majority studies highlighting these threats come from industrialised agriculture in temperate countries global North. However, more than 30% food production produced by smallholder farmers, particularly Africa. We know very little about impact farming practices on arthropod communities and associated ecosystems dryland agroecosystems. investigated trophic group composition (detritivorous, herbivorous, predatory & mixed feeders) levels ecosystem functions replicated maize fields, paired adjacent natural bushveld habitats edge between them north-eastern Namibia central-eastern Botswana during dry wet seasons. Predator activity densities differed significantly depending season, with higher numbers season lower compared to fields.

Functional diversity of ground beetles improved aphid control but did not increase crop yields on European farms

Ecological Applications, Год журнала: 2024, Номер 34(8)

Опубликована: Окт. 7, 2024

Abstract Land‐use intensification is often associated with a decline in functional diversity, potentially undermining the provision of ecosystem services. However, how changes traits affect processes remains poorly understood. Variation trait values among species community may drive processes. Alternatively, mass ratio hypothesis proposes that dominant local are related to Using data from 159 farms six European countries, we quantified impact and landscape‐level land‐use intensity on ground beetles as pest control agents. We then assessed extent which diversity community‐weighted mean relate cereal yield. In addition, responses land use effects different yield varied their compare relative studied. Functional improved aphid removal, but did not translate into higher crop yields. Pest aphids was enhanced by proportion smaller, mobile preference for vegetation layer. Smaller, predatory communities The magnitude were more strongly influenced body size than other traits. Our study provides evidence reduced management can improve supporting small‐sized, macropterous beetles. contrast claims ecological intensification, our joint analysis direct indirect via suggests services cannot compensate gap due reduction intensity.
