Polylepis species represent one of the most important and endemic woodlands of the mid- and high-elevation regions of the Andean Cordillera. I provide a review of the current situation of Polylepis woodlands, discuss the potential effects of various conservation measures and consider the likely impact of climate change on tree phenology and tree regeneration, aiming to foster the conservation and sustainable management of these woodlands through proper environmental planning. I argue that in addition to the delineation and extension of protected areas, it is essential to incorporate actions such as forestation, forest policies, environmental education and local community participation. To be effective, conservation measures should be implemented in an international transdisciplinary research framework and in harmony with site-specific conditions. Finally, given the likely but uncertain influences of climate change on Polylepis woodlands, further research (and communication of that research) is needed to improve forest management strategies and research priorities for the Andean region.
Lotus sanguineus is one of the endemic taxa from Mediterranean Region of Turkey. It has hitherto been known from type locality and was assessed under VU and EN categories despite the lack of information on the population size, number of location and habitat quality. This study aims to determine the global conservation status and conservation strategies of the narrow endemic species. We collected all available data and evaluated them with the field studies. We reported the sizes of populations, altitude, coordinates, habitat types and the threats it faces for each locality. GeoCAT analyses at global levels indicate the extent of occurrence 19.965 km2 and area of occupancy 9 km2 and there could be an inferred decline due to habitat loss and fragmentation of the original population, suggesting this species might be classified as Critically Endangered, based on criterium B1ab (i, ii, iii) + 2ab (i, ii, iii) in the Red List categorization. Conservation priorities include life history and ecology studies, in-situ conservation, population monitoring and ex-situ conservation to prevent the destruction of the existing gene pool.
Food and nutritional (in)security remain an important matter of concern, especially in developing countries. Despite the efforts to enhance food security among smallholder soybean households, the proportion of the undernourished population in Butere Sub-County still remains high for unknown reasons. Therefore, the purpose of this paper is to examine the determinants of food security among smallholder soybean households in Butere Sub-County, Kenya. The study adopted the exploratory research design. A multi-stage sampling procedure was used to select a sample of 201 respondents. Cross-sectional data were gathered through face-to-face interviews using pretested semi-structured questionnaires and analyzed using ordered logistic regression model. Household Food Insecurity Access Scale was used to measure and categorize the soybean household food (in)security status. The results revealed that the household food (in)security status differed across soybean households and was greatly influenced by an interplay of socio-economic, market, and institutional factors. Age of the household head negatively influenced food security, whereas the level of soybean commercialization, education, livestock units, network density, extension visits, and credit access were positively associated with household food security. The study recommends policy interventions that seek to ensure intensive literacy development, frequent extension and training, improved access to credit, and reinvestment in productive assets or inputs for increased production, commercialization and food security. Strengthening of social ties and increased allocation to safety net programs for the aged, vulnerable, and resource-poor households are also recommended.
The common bean (Phaseolus vulgaris L.) has been the subject of a number of studies and has been described by many authors as a legume with low nitrogen fixing potential compared to other legume species. The first objective of this study is to assess the development and growth of P. vulgaris L. var. Djedida and its yield at different developmental stages (vegetative, flowering and fruiting), in the presence and absence of nitrogen fertilizer (Urea 46) in an arid climate and in a soil containing high level of CaCO3 and assimilable phosphorus. The second objective is to carry out a survey on nodulation, number of spores and mycorrhizal infection under these conditions. The results showed that the nitrogen fertilizer amendment is mainly significant (p< 0.0001) for various morphological parameters. Indeed, great improvement was observed on the majority of the morphological parameters with considerable percentages. However, no significant effect was reported for the roots length. In addition, a negligible number of nodules were obtained in the plot without fertilization and no significant effect on the number of spores was recorded. Furthermore, the effect of fertilization on the arbuscular intensity (a%, A%) and on mycorrhizal colonization (M%, m%) of the roots was found to be significant. The soil in the arid region of Biskra showed significant mycorrhizogenic potential, although the conditions in this region were not very favorable for their development, which could constitute an effective biological resource to improve the tolerance of host plants to biotic and abiotic constraints.
This study deals with the diversity of forest vegetation in the Slivenska Mountain (Eastern Stara planina) and presents a contemporary classification scheme for the identified syntaxa. A total of 137 relevés were collected and analyzed using specialized software (JUICE 7.0 and PC-ORD Version 4). As a result, forest vegetation is classified into 10 associations, 3 subassociations, 4 variants and 5 communities They belong to 7 alliances, 5 orders and 3 classes: Carpino-Fagetea sylvaticae, Quercetea pubescentis and Alno glutinosae-Populetea albae. The recorded 18 distinguished vegetation groups show a relatively high diversity of forest plant communities of the study area.
The study assessed coping strategies adopted during economic recession by male and female members of rural households in Osun State, Nigeria. The study specifically examined the perceived causes of economic recession, investigated the perceived effects and identified the coping strategies adopted by the male and female members of the rural households during economic recession and their level of adoption. A multistage procedure was used to select 120 respondents from 6 local Government Areas of the State. An interview schedule was used to collect data from the respondents. The collected data were analysed using appropriate descriptive and inferential statistics such as frequency counts, percentages, means and independent T-test analysis. The mean ages of the male and female respondents were 45.2 ± 14.1 years and 37 ± 12.6 years respectively. The majority of the males (78.3%) and females (80%) were married with the mean household size of 7 ± 3 people for the male and 6 ± 2 for the female respondents. The cause of economic recession mostly perceived by the male and female respondents was poor economic planning (mean=3.87, 3.77), while prioritizing spending (mean=2.80, 2.52) was the most adopted strategy by both males and females. No significant difference was found in the effects of economic recession on the male and female respondents (t = -0.19; p >0.05) and likewise no significant difference was found in their economic recession coping strategies (t=0.115; p ≥ 0.05). The study concluded that there was no significant difference in the economic recession coping strategies between the male and female members of rural households in the study area.
The study assessed the gender involvement of sedentary Fulani in dairy farming practices in Osun State, Nigeria. A multi-stage sampling procedure was used to select 256 respondents from 12 Local Government Areas (LGAs) inhabited by the sedentary Fulani in the study area. Interview schedules were used for quantitative data collection. Data were analyzed and interpreted using descriptive statistics such as frequency counts, percentages, means and standard deviations while one-way ANOVA was used to draw inferences on the hypothesis. The results showed that the mean age of the male and female respondents was 34.05 ± 12.49 years and 33.33 ± 13.14 years respectively. The majority of the male (85.9 %) and female (89.8 %) respondents had no formal education. The mean herd size of male and female respondents was 20 ± 2 and 5 ± 2 heads of cattle respectively. All of the male respondents indicated that fencing, grazing and milking were male gender roles, while all female respondents indicated that cleaning of pens, sales of milk/milk products and processing of milk were female gender roles. The study showed that 42.7% of the male and10.2% of the female respondents had high level of involvement in dairy farming activities, while 24.7% of the male and 44.2% of the female respondents had low level of involvement. Further results revealed that there were significant differences (F = 312.80) between the male and female respondents in their involvement in dairy farming practice. The study concluded that there is gender gap in male and female involvement in dairy farming practices.
