Soil degradation in sub-Saharan Africa is a serious problem that causes declines in agricultural productivity linked to hunger and poverty. The study was conducted in the Kulkullessa sub-watershed of Goro Gutu District in Eastern Ethiopia to assess the effects of climate-smart soil and water conservation (SWC) practices and slope gradient on selected physicochemical properties of the soil and the soil’s organic carbon stocks. The farmland conserved by stone bund (SB), bench terrace (BT), and gras strip (GS) five years after construction with two slope gradients (15-20%) and (21-30%) was selected. Twenty-four composite soil samples were collected from a depth of 20 cm and tested in the Haramaya University soil laboratory. The study found that climate-smart SWC practices were very effective on the soil physicochemical properties and soil organic carbon stock (SOCS) of the study area. Similarly, the slope gradient brought considerable variation in soil physicochemical properties and soil organic carbon stock. On farmland that a bench terrace had preserved, the bulk density (BD) value was lower. The recorded value for total porosity on the farmland conserved by BT was also positively higher and significant (p ≤ 0.05). Likewise, the higher mean values for micronutrients and SOCS were recorded on farmlands conserved by SB, BT, and GS in contrast to the values recorded on non-conserved farmland (NCF) in the study area. Based on the study findings, climate-smart soil water and conservation practices have outstanding potential for improving soil physicochemical properties essential for agricultural crop production, climate change adaptation, and strengthening smallholder farmers’ resilience.

This research aimed to evaluate the efficacy of contemporary digitization methods for archaeological sites, specifically focusing on aerial approaches. The study is concentrated on the examination of two primary methods: LiDAR sensor and photogrammetry. The chosen case study revolves around the Camp of the V Macedonica Legion, a pivotal feature of the former Roman city now known as Turda, a city in Cluj County, Transylvania, Romania. Through analysis and comparison, the paper revealed that each of these aerial 3D scanning techniques possesses unique strengths, which, when combined, offer a comprehensive approach to archaeological digitization. These complementary attributes must be carefully considered and integrated considering the specific requirements and objectives of the archaeological project at hand when selecting the appropriate method. Furthermore, the research underscores the pivotal role of presenting archaeology in 3D, emphasizing its significant impact on both public and academic audiences. Achieving this presentation necessitates the utilization of specialized software for modelling, rendering, and animating objects of interest, thus enhancing the accessibility and engagement of archaeological findings. The comprehensive findings of this study demonstrate the vast potential offered by aerial 3D scans in the field of archaeology. Moreover, it serves as a potential call for the meticulous selection of the analysis method, recognizing its crucial role as a valuable tool for researchers and archaeologists. By leveraging 3D technologies in their activities, professionals in the field can significantly enhance the accuracy, depth, and accessibility of their archaeological investigations, thereby enriching our understanding of the past.

This study aimed to investigate the use and effectiveness of Indigenous Knowledge Systems (IKS) in managing landslides in Kanungu District, Uganda. The study used the Likert scale and the multivariate probit (MVP) model and found that marginalization was a significant challenge facing local interventions in landslide disaster management. Factors such as farm size, credit availability, social group membership, access to extension services, farming experience, accessibility of weather and climatic information, and perception of climatic changes influenced the adoption of IKS, both positively and negatively. The study concludes that education programs should focus on farmer capacity building to mitigate landslide risks and emphasizes the application of IKS in landslide hazard management.

Beilschmiedia mannii (Meisn.) Robyns and Wilczek is an underutilised fruit tree valued for its nutritional benefits, but threatened by habitat destruction in Nigeria. Morphological characterisation was performed in order to elucidate the insufficient information on its morphological attributes in southwestern Nigeria. The study aimed at characterising the species population using the fruits, seeds, leaves, and the trees morphological attributes according to the habitats georeferenced by GPS. Different mother trees of the species were sampled for the study. Two distinct fruit colours (green and black) were identified, along with corresponding seed colours (red and cream). The species exhibited three primary fruit shapes, with corresponding seed shapes (ellipsoid, globose, and oval). B. mannii was encountered in the riparian, mangrove, and upland habitats. Significant differences were observed in the fruit weight, width, and length, seed weight, length and width, as well as mesocarp weight, leaf length and width between the two distinct colours, and amongst the shapes, and the habitats. The dendrogram-based clustering analysis revealed that the green morphotype and ellipsoid-shaped fruits formed the first cluster, while combinations of black and green fruits resulted in morphotypes with globose and ovate shapes in the second cluster. These findings highlight the presence of intraspecific diversity in the species with significant potential for species selection, breeding and improvement. This empirical data has important implications for the initiation of species domestication and conservation efforts.
Beilschmiedia mannii (Meisn.) Robyns and Wilczek 是一种未得到充分利用的果树，其营养价值很高，但在尼日利亚却受到栖息地破坏的威胁。为了澄清尼日利亚西南部有关该物种形态特征的信息不足的问题，我们对该物种进行了形态特征描述。该研究旨在根据全球定位系统提供的栖息地地理坐标，利用果实、种子、叶子和树木形态特征来描述该物种种群的特征。研究对该物种的不同母树进行了取样。确定了两种不同的果实颜色（绿色和黑色）以及相应的种子颜色（红色和乳白色）。该物种的果实有三种主要形状，种子也有相应的形状（椭圆形、球形和椭圆形）。在河岸、红树林和高地栖息地都发现了甘露百合。在两种不同颜色、不同形状和不同生境之间，果实重量、宽度和长度，种子重量、长度和宽度，以及中果皮重量、叶片长度和宽度均存在显著差异。基于树枝图的聚类分析显示，绿色形态和椭圆形果实构成第一聚类，而黑色和绿色果实的组合导致球形和卵形形态构成第二聚类。这些发现凸显了该物种种内多样性的存在，为物种选择、育种和改良提供了巨大潜力。这些经验数据对启动物种驯化和保护工作具有重要意义。

Climate change has exacerbated difficulties for both the environment and humans in recent years, with major consequences on the resilience and ecological diversity of forests, including those of silver fir (Abies alba Mill.). Because cold stress is an important challenge to silver fir seedling growth, particularly in the early phases of development, the goal of this study was to find potential genetic resources with appropriate responses to the action of low temperatures. Thus, traits of interest were studied in the early stage of seedlings from seven different Romanian provenances. Soil electrical conductivity, root weight, and total seedling weight were found to be related to seedling growth and biomass elements. The results revealed substantial differences depending on geographical origin. Garda Seaca provenance had the highest seedlings tolerance. Exposure to varying low temperatures revealed minor variations between seedlings from the control and those treated to −20 °C, which might be explained by the current temperatures in Romania’s silver fir producing area. However, exposing to −40 °C all seedlings showed deterioration. Soil electroconductivity reduced as exposure temperature decreased, emphasizing the link between cold stress and soil effects on fir seedling growth. Some Romanian provenances could be useful for future silver fir breeding or afforestation and reforestation operations.
近年来，气候变化加剧了环境和人类面临的困难，对包括银冷杉（Abies alba Mill.）在内的森林的恢复能力和生态多样性造成了重大影响。由于低温胁迫是银冷杉幼苗生长的一个重要挑战，尤其是在发育的早期阶段，因此本研究的目标是找到对低温作用有适当反应的潜在遗传资源。因此，本研究对来自罗马尼亚七个不同产地的幼苗早期阶段的相关性状进行了研究。研究发现，土壤导电率、根重和幼苗总重与幼苗生长和生物量元素有关。研究结果表明，不同产地之间存在很大差异。加尔达-西卡（Garda Seaca）产地的秧苗耐受性最高。在不同的低温条件下，对照组和在-20 °C条件下处理的幼苗之间的差异很小，这可能与罗马尼亚银冷杉产区目前的气温有关。然而，在零下 40 °C的环境中，所有幼苗的适应能力都有所下降。土壤电导率随着暴露温度的降低而降低，强调了冷胁迫和土壤对冷杉幼苗生长影响之间的联系。罗马尼亚的一些产地可用于未来的银冷杉育种或造林和再造林活动。

Northeastern states, Sikkim, Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura – falling in Eastern Himalaya and Indo-Burma hotspots, house a large number of indigenous communities, mostly forest and forest fringe dwellers, whose economy is also dependent on livestock. To maintain the health of various livestock they practice ethnoveterinary medicine (EVM) which is so important yet scarcely studied. This review is based on eleven core research publication on EVM practices representing these states. Several other peer reviewed publications were also consulted for analysis and synthesis of the contents like, Physiography and Phyto-diversity, Indigenous Communities, Livestock and Common Ailments, Healer Plants, Bio-Active Components and Drugs, Potential Distribution. Analysis revealed that only twenty-three communities out of >200 are researched upon. All most all the livestock are covered in the studied area by using herbal preparation from 195 plants. However, research on pharmacological and distributional details is scanty and needs further exploration since similar plants (Asparagus racemosus, Allium sativum, Azadirachta indica, Cannabis sativa, Centella asiatica, Curcuma longa, Drymaria cordata) for ethnomedicine use (for humans) are recorded from various locations and used by different communities. Nevertheless, current compilation of data seems to be useful in the sense of preservation of the indigenous knowledge, otherwise on decline due to oral transfer from one to another generation.

Spiders are generalist predators which have been found to benefit paddy crops as biological control agents. The present study was taken up at Bargarh district of Odisha, India to study and compare the spider diversity in the two cropping seasons with effect of abiotic factors on species abundance in rice lands. The observations were made across two cropping seasons during Rabi and Kharif cropping seasons to assess the seasonal influence on spider population. Seventeen families of spiders were recorded during the study out of which Rabi cropping season recorded 17 families, while Kharif season recorded 13 families. In total, 60 genera and 93 species were identified based on 2694 individuals collected where females recorded 67.6% while 18.8% were juveniles and 13.6% were male spiders. The highest species diversity was found in Araneidae family (28) while Tetragnathidae (n=1106) recorded the highest abundance. The correlation of spider abundance with abiotic factors was found to vary in both cropping seasons, where rainfall and windspeed were found to control spider colonization to a considerable extent but not found significantly corelated to abundance, while it was strongly correlated positively with relative humidity. Spider abundance and species diversity was more in the Rabi season (summer crop). Five dominant families were reported commonly from both cropping seasons: Tetragnathidae, Araneidae, Lycosidae, Salticidae and Oxyopidae. Spiders observed during the study belonged to seven different feeding guilds.

The improved economic performance and development created some new challenges, such as high urbanisation rates and environmental degradation worldwide. In this context, the presented article focuses on the relationships among urbanization, specifically the urban attraction challenge, and its impact on ecosystems in El-Faqih Ben Saleh City in Morocco. Besides, the urban attraction challenge refers to the dynamics that draw individuals to cities, encompassing economic opportunities, education, healthcare, and cultural amenities, while also posing challenges like overpopulation and resource strain. The article discusses how urban expansion often clashes with rural areas, affecting land use, the environment, and social dynamics. The boundaries between these urban and rural areas pose multiple issues and need an integrated planning strategy. The study employs Geographic Information System (GIS) technology, using high-resolution Google Earth Pro imagery, to assess the impacts of urbanization on the environment in El-Faqih Ben Saleh City. The obtained results reveal the city’s rapid urban growth and its consequences, such as deforestation, pollution, and agricultural land loss. The findings highlight the need for sustainable urban planning, green infrastructure, and mixed land use to mitigate these impacts. The case study of El-Faqih Ben Saleh City, considered as a small city to understand the broader dynamics of contemporary urbanization, emphasizes the importance of balancing urban growth with environmental and agricultural preservation.
经济表现和发展的改善带来了一些新的挑战，例如世界范围内的高城市化率和环境退化。在此背景下，本文将重点关注摩洛哥法齐赫本萨利赫市城市化之间的关系，特别是城市吸引力挑战及其对生态系统的影响。此外，城市吸引力挑战是指将个人吸引到城市的动力，包括经济机会、教育、医疗保健和文化设施，同时也带来了人口过剩和资源紧张等挑战。本文讨论了城市扩张如何经常与农村地区发生冲突，影响土地利用、环境和社会动态。这些城市和农村地区之间的边界构成了多重问题，需要一个综合规划战略。该研究采用地理信息系统(GIS)技术，利用高分辨率的Google Earth Pro图像，评估El-Faqih Ben Saleh市城市化对环境的影响。获得的结果揭示了城市的快速发展及其后果，如森林砍伐、污染和农业用地流失。研究结果强调了可持续城市规划、绿色基础设施和混合土地利用的必要性，以减轻这些影响。El-Faqih Ben Saleh市的案例研究强调了平衡城市发展与环境和农业保护的重要性。El-Faqih Ben Saleh市被认为是一个小城市，可以了解当代城市化的更广泛动态。
