The synthetic textiles are most responsible for non-biodegradable microplastic release during laundry washing cycles. European directives try to promote and encourage the use of natural textiles, such as delicate fabrics, as a new ecological approach. Delicate fabrics aren’t resistant to multiple microdamages by commercial products with proteases, rapid wear, loss of elasticity and fabric strength, and colour fading due to protein structure of these fibers. The aim of this research was to evaluate the beneficial effects of transglutaminase (TGase) in household products for the regeneration of microdamages and regulation of the elasticity of delicate fabrics during laundry washing cycles. In the present study, the effects of TGase on silk and wool were investigated by modern methods: scanning electron microscopy (SEM) and deformation-strength technique using Shimadzu AG 10kNX. SEM showed that the bonds formed by TGase exhibited high resistance of fibers before and after protease application. TGase in laundry washing gel provided the restoration of silk and wool fibers up to 85% after 10 washing cycles. The elasticity of delicate fibers was increased by 16% after 1 wash cycle. The strength of silk and wool was improved by 2 and 5 times, respectively, with decrease in fiber elongation. Thus, TGase can be promising compound to provide the deep regeneration of microdamages and increase longevity of delicate fabrics.
Experimental and Numerical Investigation of Energy Absorption Characteristics of a E-Glass/Epoxy Crash Box
Authors: Bilmez S A , Taşdemirci A
Published: March 2024

Crash boxes are energy absorbing components generally placed at the front end of cars to reduce the amount of damage at especially low impact velocities. The number of electric vehicles has been increasing recently, so weight reduction studies are. For this reason, lighter glass or carbon fiber reinforced composite crash boxes are preferred instead of steel ones. In the current study, the dynamic compression behavior of a rectangular cross-section thin-walled composite crash box was investigated both experimentally and numerically. The main aim of the study was to understand the effective damage modes and monitor the deformation sequence experimentally and numerically. Once the numerical model is verified then it can be further used to reveal the behavior at different impact velocities and geometries. The methodology followed in the study first started with the static mechanical characterization of the composite material. Within the scope of this study, 2×2 twill-woven glass fiber/epoxy crash boxes were produced using the vacuum bagging method. Quasi-static compression and tension tests were carried out in accordance with ASTM D3039 and ASTM D6641 standards. In the numerical part, Radioss finite element package was used with the material model of MAT 25 along with the failure option of Tsai-Wu. Experimental dynamic crushing tests of the crash box was carried out using a custom made drop-weight tester at impact velocity of 4.4 m/s and dropping mass with 450 kg. The material model constants were obtained once the coupon based static and dynamic tests were completed. From the dynamic crushing tests, maximum and mean force values of 225 and 65.0 kN were noted, respectively. There is close agreement between the experimental and numerical results both in terms of force and displacement values. This verified numerical model can further be used to investigate the crushing characteristics at different impact conditions.

The exciton-polaritons derived from the light-matter interaction of an optical bound state in the continuum (BIC) with the strong excitonic resonance in a transition metal dichalcogenide (TMD) monolayer can inherit ultra-long radiative lifetimes and significant nonlinearities up to room temperature. Yet such realization can be challenging with conventional approaches to the photonic cavity design, typically due to poorly-resolved Rabi splittings at room temperature and an unstable energy positioning of the BIC state. We show and experimentally validate a strategy to dramatically improve the state-of-the-art on both points, by embedding a tungsten disulfide (WS2) monolayer deep within a Bloch-surface-wave stack, where the photonic mode is moulded by a 1D photonic crystal with a compound periodicity. In particular, we introduce a deterministic placement principle to the design of the PhC, allowing to stabilize the energy positioning of a topologically-protected BIC polariton eigenstate, with an effective mass which we can robustly pre-assign at choice as either positive or negative. This is in stark contrast to typical waveguide realizations of polariton BICs: only negative polariton effective masses can be commonly achieved, while sudden jumps to a weaker-interacting positive-effective-mass BIC are at the same time possible upon small perturbations, in fact hijacking the advantage from a topological protection when present.
Landscape position mediates drought vulnerability in California valley oak (Quercus lobata)
Authors: Trumper Matthew L , Griffin Daniel , White Michael D
Published: March 2024

Future climate change will exacerbate drought stress in water-limited ecosystems. However, topography can alter the fine-scale climatic and hydrologic conditions that mediate plant response to meteorological drought. Here, with six new valley oak (Quercus lobata) tree-ring width chronologies, we assess how topography acts as a mediating factor on tree growth and drought sensitivity. Because valley oaks are known to be highly dependent on subsurface water, we predicted that trees growing in riparian sites would be less sensitive to precipitation variability due to greater access to groundwater. Trees were sampled in the Tehachapi Mountains of California across a landscape gradient of sites ranging from 375–1650 m elevation and across upland (55–69 m mean height above nearest drainage) and riparian (2–6 m mean height above the nearest drainage) hillslope positions. Interannual tree growth patterns and drought sensitivity varied substantially in association with hillslope position and elevation. Valley oak radial growth showed a consistently weaker response to precipitation at riparian sites. The influence of hillslope position on drought sensitivity varied with elevation, such that the riparian buffering effect was weakest at sites higher in the watershed and strengthened, progressively, toward the lower elevation sites with greater climatic water deficit. Upland tree growth exhibited a strong response to high-frequency interannual precipitation variability at the high elevation site, whereas trees at lower elevation upland sites responded more to low-frequency decadal trends in precipitation, possibly reflecting hydrogeological processes by which precipitation feeds groundwater lower in the watershed. Our results are consistent with groundwater-dependence of valley oak and indicate that riparian habitats are the most likely refugia for the species during prolonged drought.

The international community, through treaties such as the Paris agreement, aims to limit climate change to well below 2 °C, which implies reaching carbon neutrality around the second half of the century. In the current calculations underpinning the various roadmaps toward carbon neutrality, a major component is a steady or even expanding terrestrial carbon sink, supported by an increase of global forest biomass. However, recent research has challenged this view. Here we developed a framework that assesses the potential global equilibrium of forest biomass under different climate change scenarios. Results show that under global warming carbon storage potential in forest aboveground biomass gradually shifts to higher latitudes and the intensity of the disturbance regimes increases significantly almost everywhere. CO2 fertilization stands out as the most uncertain process, with different methods of estimation leading to diverging results by almost 155 PgC of above ground biomass at equilibrium. Overall, assuming that the sum of human pressures (e.g. wood extraction) does not change over time, that total forest cover does not change significantly and that the trend in CO2 fertilisation as it is currently estimated from satellite proxy observations remains, results show that we have reached (or are very close to reaching) the peak of global forest carbon storage. In the short term, where increased disturbance regimes are assumed to act quicker than increased forest growth potential, global forests might instead act as a carbon source, that will require even more effort in decarbonization than previously estimated. Therefore, the potential of forests as a nature-based solution to mitigate climate change brings higher uncertainties and risks than previously thought.

A region’s ability to expand and flourish depends heavily on its road system. Roads that are smooth and effective facilitate communication between different locations, the movement of people, and the transit of commodities. Thus, people movement within a region is greatly impacted by the quality of road service. One of the principal thoroughfares in Malang Regency is Kawi Road, which has two two-way lanes without a median and an effective road width of eight meters. It is a primary collector hierarchy (2/2 UD). There is a lot of traffic on Kawi Road since it connects two local activity hubs, Blitar and Lumajang, and acts as a national road. This study’s main objective is to characterize Kawi Road in Kepanjen District, Malang Regency, with regard to its attractiveness and generation of land use, performance, and modeling. In compliance with the 2014 Indonesian Road Capacity Guidelines, the following research methodologies were used: road capacity analysis, saturation degree analysis, multiple linear regression analysis, and road service level analysis. The research makes use of field observation data. According to calculations, Kawi Road can handle 2826.63 passenger car units per hour. Its peak performance was reached between 15:00 and 16:00, or 0.87 (LOS E).

Published: March 2024

Rain is the main factor causing landslides; rainwater can enter the soil through rock gaps and then accumulate in the impermeable layer; the layer then becomes a slip plane that triggers the landslide. This study aims to determine the level of influence of rainfall on landslide events in Batu City in 2021. Batu City is one of the main tourist cities in Indonesia, so security and safety are the main factors that must be considered. The method used in this research is a descriptive analysis of rainfall and landslide data. The analysis process was approached with a literature review and simple mathematical calculations visualized on a 2D map using GIS and Geostudio to simulate groundwater infiltration and safety factors. The results showed that the number of landslide events increased with increasing rainfall. The rainfall for Batu City is between 1749.15-2238.73 mm, while most landslides occur in January and February. Landslides in Batu City in 2021 occurred 78 times, most of which occurred in Songgokerto Village (15 incidents). The intensity of rainfall greatly influences the occurrence of massive landslides; apart from changing the physical properties of the soil or rock, the mechanical properties also change rapidly. The wetting-drying process will make the properties of soil particles and rock aggregates more vulnerable or the durability index of the soil and rock layers will decrease due to continuous rainfall.

The Disaster Resilient Village Program (Destana) is a program that held by National and Regency Disaster Management Agency. However, the connection of Destana to the holistical aspect such as geologic landscape aspect is a discoursive material that appeals to many disaster management practitioners, scholars, international donors or governments. This study aims to explore the urgency of Disaster Resilient Geosites-Village Program from the risk condition, regulation, and community perception. Geopark Jogja and Geopark Gunung Sewu with their 20 geosites was purposively selected as the site of investigation. A qualitative research method involving focus group interviews (FGI), interviews, risk analysis using InaRisk, and regulatory analysis was used to explore and capture urgency of Disaster Resilient Village Program in geosites context, that called as Disaster Resilient Geosites-Village Program. Based on the results, several essential urgency were underlined for all approaches as follows: (1) all village with geosites have high to medium risks of disasters (2) geosites facing decline in the physical and environmental carrying capacity, which consequently leads to increased disasters risks for the community villages (3) local wisdom that develops in geosite areas is beneficial for disaster risk reduction efforts, and (4) well-conserved geosites support the local economic resiliency through tourism and geoproducts. These urgencies are expected to improve the community resiliency through a program aimed at reducing disaster risk through the mainstreaming of geosite functions into village-level policies and actions to enhance community resilience. This urgency study can stimulate community-level pilot projects that can be replicated in other areas or even elevated to government-level policies

Floods disaster have caused much damage and disruption to the continuity of education. Therefore, disaster risk reduction efforts must be carried out, especially in the school environment. This study aims to analyze how Disaster Risk Reduction efforts are conducted in elementary schools in the Grogol flood-prone area, Indonesia. This research is quantitative research with a survey design. Data collection is carried out using questionnaires and documentation. The instrument used is a closed questionnaire with indicators of Disaster Risk Reduction, including knowledge and attitudes, school policies, preparedness planning, and resource mobility. The population in this study were five elementary schools located in flood-prone areas of Grogol, Indonesia, including SDN Madegondo 1, SDN Madegondo 3, SDN Pandean 1, SDN Kadokan 1, and SDN Pandean 2. Respondents in this study were 40 teaching staff who consisted of principals, homeroom teachers, and teachers from each elementary school. The data analysis technique used is descriptive statistical data analysis. The results of this study were shocking; even though floods overflow the river almost every year, all schools in the flood-prone areas were classified as in the low class in implementing Disaster Risk Reduction for flood disasters. One factor that has a dominant influence was the absence of an official policy from the government that officially regulates the implementation of Disaster Risk Reduction for flood disasters in the region. The results of this study are expected to be used as a basis for implementing disaster risk reduction by elementary schools against floods.

The urban heat island (UHI) condition has received significant attention because it has the potential to negatively impact life quality and comfort, especially livability and level of comfort. Semarang City, the capital of Central Java, has been attracting many people to live and causing land use conversion to built-up areas. This study aims to observe the land surface temperature (LST) trend and to analyse the UHI spatiotemporal pattern in Semarang based on satellite time series data within 10 years. Land cover and LST were extracted from Landsat data of 2008, 2013, and 2019. Based on the results, it was observed that the vegetated area has reduced from 20.347 Ha to 7.241 Ha, while the average LST value has increased from 29.24°C to 31.31°C in 2008 and 2019 respectively. We also found that the UHI pattern, which was initially detected only in a few areas in 2008 and was focused in the city centre, has gradually spread to the east and south of Semarang in 2019. The result also shows the spatiotemporal trend of land cover conversion and UHI areas, which can be beneficial for mitigation planning in the future.

Mitigation of land fires that occur in wetland areas, especially in peatlands, continues to be addressed by the community in Banjarbaru, South Kalimantan Province. Local wisdom that applies in the community, which includes local knowledge, local value, local skills, local sources, and regional society solidarity, is expected to reduce the risk of land fires. The research objective is to analyze the value of local wisdom for peatland fire reduction in the wetland area of South Kalimantan. The respondents interviewed were 30 from the Community and Fire Care Community or Masyarakat Peduli Api (MPA) members. Local wisdom prevailing in the community can reduce the risk of peatland fires. The community has the local knowledge, local value, local skills, local sources, and local society solidarity in managing peatlands. Peatlands managed by communities are less likely to burn than unmanaged lands. The tapulikampar system is a local wisdom in the Banjar community to prepare agricultural peatlands without burning. The Banjar community also has good skills in managing peatlands, which are not easily damaged and prone to burning. Cooperation between community groups in MPA is also well implemented in monitoring land fires and suppression efforts. The community makes maximum efforts so that peatlands are not damaged, and the risk of fire can be reduced because potential resources on peatlands must be passed on to the next generation.
The assessment of flood hazard in Pondok Keumuning village of Langsa City, Aceh due to heavy rain in 2020

Published: March 2024

Langsa faces the recurring threat of floods every year, primarily caused by high rainfall resulting in surface runoff in the Langsa Watershed. However, there is uncertainty regarding the specific causes of flooding in the city. This research discusses the flood hazards generated by Langsa River due to high rainfall in Keumuning Village, Langsa City, in 2020. The data utilized in this study includes daily rainfall data obtained from PTPN I Langsa, specifically from the Kebun Lama (KLM), Kebun Baru (KBR), and Tualang Sawit (TWS) stations. Additionally, observed water level data is collected from the Keumuning water gauge station operated by the Aceh Irrigation Agency. Since there is no river discharge record at the Keumuning water gauge station, the Nreca method is used to analyze the direct runoff from the Langsa Watershed due to rainfall, linking it to the water level at Keumuning. Historical flood event data is compiled from the Regional Disaster Management Agency of Langsa City, online media sources, and interviews with flood-affected communities. The research findings indicate that floods in Keumuning Village, Langsa, are triggered by high rainfall, leading to increased river discharge as a result of heavy rainfall at the TWS station (located upstream in the Langsa Watershed) with a 2-year return period. This can result in flooding for the villages around the Langsa River. Similarly, suppose rainfall reaches a 2-year return period at the KLM and KBR stations situated within the middle and downstream of the Langsa Watershed. In that case, it poses a flood threat to the upstream villages along the estuary branches. However, further studies are necessary to assess compound floods triggered by tidal water levels, rainfall, and river discharge in the vicinity of these estuary branches.

Remote sensing technology advancements have opened novel possibilities for precise and effective landslide investigation. Because both regions have rocky topography, this study will employ unmanned aerial vehicles (UAVs) or drones to examine landslide activity on the west side of Mount Lawu, namely in Nglelaka Hamlet, Segorogunung Village, Ngargoyoso District and Guyon Hamlet, Tengklik Village, Tawangmangu District. Landslides are caused by the rocks and their geological conditions. As a result, extensive monitoring is essential to ensure that mitigation activities are carried out exactly. The spatial and descriptive analysis strategy was employed in this study. Data collecting methods used included landslide censuses and field surveys. A Geographic Information System was then used to process the data. According to the research findings, the landslide in Nglelaka Hamlet was of the translational kind, but the landslide in Guyon Hamlet was of the termite type. The findings of this study helped us better understand the dynamics of landslides in diverse locations, particularly in difficult-to-reach areas, and demonstrate how beneficial UAVs can be in gathering data for disaster management and community resilience. Drones for landslide studies offer valuable information to local governments and stakeholders, allowing them to develop preventative measures and emergency response plans, lowering the impact of landslides on residents and infrastructure.

Land use with mixed crop cultivation practices, or agroforestry, is currently important for small farmers because it provides economic resilience and ecosystem-based solutions for climate change adaptation. This research is to examine the role of agroforestry in the homegarden of communities living on peatlands in supporting household economic resilience and the impact of climate change on their livelihoods. In-depth interviews using questionnaires and field observations were carried out for data collection. The research results show that agroforestry based on fruit plants such as Durio kutejensis, Artocarpus champeden, Lansium domesticum, and Parkia speciosa is found in Pulang Pisau Regency, while the mixed crop pattern of Pinang catechu, Coffea liberica, and Cocos nucifera is found in West Tanjung Jabung Regency. This type of land use provides economic stability for farming households on peatlands. Farmer experience and knowledge, species preferences, markets, land ownership, and labor availability are considered in implementing mixed cropping systems. Access to credit and capital and increasing farmers’ abilities during harvest and post-harvest are really needed by farmers. Therefore, support from various stakeholders and pro-farmer policies is needed so that mixed cropping systems can improve the livelihoods of small farmers and reduce their vulnerability to climate change.

Published: March 2024

Forest fires in Türkiye have devastated 2.5 million hectares of habitat over four decades, posing a grave threat to Mediterranean forest ecosystems. This study compares machine learning techniques: Decision Trees (DT), Naive Bayes (NB), Random Forest (RF), Artificial Neural Networks (ANN), and Support Vector Machines (SVM), for predicting forest fire vulnerability. Using a dataset encompassing various factors like precipitation, soil moisture, temperature, humidity, wind speed, land cover, elevation, aspect, slope, proximity to roads/electricity networks, and population density, the models were trained and tested. The dataset classified vulnerability into four classes: very low, low, moderate, and high. Evaluation metrics included overall accuracy, precision, sensitivity, F1-score, Cohen kappa, and cross-validation (CV).RF exhibited the highest performance (accuracy: 0.80, precision: 0.78, sensitivity: 0.80, F1-score: 0.78, Cohen kappa: 0.71, average CV: 0.71), predicting fire vulnerability classes very low (14.99%), low (0.68%), moderate (65.41%), and high (18.90%) with notable accuracy. DT yielded consistent results, while NB performed stably, though slightly lower than RF and DT. However, ANN and SVM demonstrated lower performance and higher variability. These findings advocate for RF as the most accurate algorithm for forest fire risk prediction, emphasizing its crucial role in proactive fire risk management strategies.

Peat fires on cleared and drained tropical peatlands continue to cause tremendous damage to their ecological functions, contribute to global warming, and reduce in health of local communities, where the fire incidents in 2019 and 2020 correlated with weather conditions. The research aims to determine and clarify the correlation between rainfall dynamics and the occurrence and severity of peat fires in degraded tropical peatlands in South Sumatra, Indonesia. The research was conducted by recording rainfall Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) data, surface and peat fuel, and peat fire area primer data from 2019 to 2020. The results show that two types of weather correlate with the size of the burned area in the Ogan Komering Ilir (OKI) regency. Temporal rainfall distribution, quantity, and duration a determining factor for the transition of surface fires to peat fires, especially in the role they play in the hydrology and moisture conditions of peat and surface fuels. This study will present the effect of rainfall in the dry and wet dry seasons on peatland fires and the extent of peat fires that occurred in two years.

This study aims to determine the types of feed pollen consumed by the bee species Tetragonula biroi. The research has the objective of providing information to the public regarding the sources of feed for T. biroi honey bees, which are located in Kuajang Village, Binuang District, Polewali Mandar Regency, West Sulawesi. The research was conducted between February and April 2020. A comparative method was employed to examine the shapes of plant pollen found around the meliponiary in comparison to the shapes of pollen discovered in honey and bee bread. Samples were prepared using the acetolysis method and stained using safranin. The research findings indicate the presence of 23 identified flowering plant species in the vicinity of the meliponiary, along with their identification in bee bread. However, only 12 species were identified in honey. Coconut pollen exhibited the highest percentage, accounting for 44.8% of honey and 38.13% of bee bread, categorizing it as a secondary pollen type.

The success of developing plantation forests relies on obtaining high-quality seeds, achievable through generative and vegetative propagation. However, some plants face constraints with generative methods, prompting the exploration of vegetative propagation alternatives. Pulai seeds (Alstonia scholaris) were used for vegetative seed propagation through the use of cuttings in this study. Genetic and environmental factors were identified as significant determinants affecting cutting propagation success. The research aimed to assess how different shoot parts impact Pulai plant cutting growth using the Water Rooting Technique (TWR), known for its simplicity and minimal requirements. Employing a randomized block design with three treatments (shoot tips, mid-shoots, and shoot bases) replicated three times, each treatment combination included 50 cuttings. Observations focused on parameters such as percent growth, shoot growth time, shoot height, root length, total dry weight, shoot dry weight, root dry weight, and shoot-to-root ratio. Statistical analysis using Analysis of Variance (ANOVA) indicated significant differences, confirmed by the HSD follow-up test. The mid-shoot treatment proved to be the most effective method in influencing all observed parameters, highlighting its importance in fostering Pulai cutting growth.
The Prophetic Body
Authors: Portier-Young Anathea E
Published: March 2024

Biblical prophecy involves more than words: it is always also embodied. After assessing the implications and origins of a logocentric model of biblical prophecy, this book proposes an alternative, embodied paradigm of analysis that draws insights from disciplines ranging from cognitive neuroscience to anthropology. The body’s vital and necessary role in prophetic mediation emerges through analysis of portrayals of prophets’ embodied religious experience and practice in diverse texts from the Hebrew Bible and Old Testament. Prophetic call narratives reveal a correspondence between embodied encounter with God and embodied mission to God’s people and a programmatic synergy of word and body. First-person narratives facilitate audience transport in ways that extend the embodiment of prophetic mediation through text to audience. Visible transformations of the prophetic body mark it as other, even monstrous, reflecting a liminal position between heaven and earth, life and death. Ascetic practice and religious ecstasy make the prophet’s body a mediating bridge. They also hold power to shape social realities. Prophetic mobility similarly links God and people across time and space. A different kind of movement, affect and emotion, likewise proves central to prophetic mediation. The prophetic body becomes a locus of interembodiment and node of circulating affect between God, people, and place. The body of the prophet is not accidental but rather vital and necessary to the prophet’s mediating role. The prophet’s embodied religious experience, transformations, mobility, and affect are both means (how mediation occurs) and objects (part of what is mediated) of prophetic mediation.
Becoming Other

Chapter 5 examines the visible transformations of Moses and Miriam in Exod 34 and Num 12. Prophetic bodies are border bodies, inhabiting but also crossing the boundary between human and divine realms. The contrasting bodily transformations of Moses and Miriam share a striking feature: each is rendered monstrous. Moses’ metamorphoses give visible, bodily form to the liminality and power of the prophetic role. His transformed body paradoxically mediates divine power and presence to the people while isolating him from them. The temporary transformation of Miriam similarly evinces her liminality and isolates her from the people. By contrast with Moses, however, her transformation effectively curtails her prophetic power by denying her access to God, people, and place.
Transformative Practice

Published: March 2024

Chapter 6 analyzes textual portrayals of the transformative practices of askêsis and incubation. By transforming the body in culturally specified ways, the prophet also claims power to transform social realities. Bodily disciplines of askêsis shape the prophet’s person. They may prepare the prophet to encounter the deity or receive revelation or be an efficacious component of prophetic intercession. Prophetic ascetic practice can strengthen, challenge, or reshape social relationships and structures and even alter the cosmos. In Exodus and Deuteronomy, Moses’ askêsis pushes up to and beyond the limits of what is humanly possible, making his body a bridge between impossibility and possibility, human and divine, death and life. His resulting transformation presages and makes possible the people’s. Incubation is less clearly attested among Israel’s and Judah’s prophets. Instead, in 1 Sam 1–3 this liminal practice emerges at a moment of national transition to inaugurate new structures of leadership and open prophetic channels of mediation that had previously been closed.
Anger and Tears

Chapter 9 considers affect and emotion as key components of prophetic embodiment. A theoretical framework drawn from neurobiology, social science, and cultural studies illumines affect’s embodied and social character while establishing its vital role in cognition, decision making, and behavior and its capacity to effect social change. In Jonah, affect is a site of negotiation and transformation. The concluding dialogue of Jonah prompts critical reflection to increase affective attunement between prophet and God. In Jeremiah, unattributed laments, interdictions against prophetic intercession, and the reversal of interdiction construct the prophet’s body as a node of circulating affect between deity, people, place, and prophet.
Peacemaking in an authoritaraian context in Africa: Promoting peace from below in Cameroon
Authors: Lefort-Rieu Claire
Published: March 2024

Cameroon, traditionally overlooked on the international peace agenda, has recently received increased attention due to mounting security challenges. Operating under an authoritarian regime that denies conflicts while promoting a narrative of stability, the course of international peace-from-below initiatives is profoundly influenced by this constrained political environment. Through in-depth case studies of three ongoing humanitarian crises—the Central African refugees’ influx, the Boko Haram/Islamic State West Africa Province insurgency, and the Anglophone conflict—this article contends that localized peace approaches, centring on grassroots reconciliation, may obscure broader structural issues, silence non-state political claims from below, and absolve the state of its responsibilities. Embracing such methodologies not only reinforces authoritarian dynamics but also exhibits a performative dimension, contributing to the establishment of a ‘victor’s peace’ in the absence of military victory.
