FINANCIAL STRESS AND FARM INSECURITY AS PREDICTORS OF BURNOUT AMONG FARMERS IN RURAL COMMUNITIES IN RIVER STATE, NIGERIA 经济压力和农业不安全是尼日利亚河州农村社区农民倦怠的预测因素
E. Emily
Many factors, including the psychological condition of burnout, consistently threaten the contemporary agricultural ecosystem in Nigeria. The present study examined farmers' burnout based on financial stress and farming insecurities in a sample of farmers recruited from different farming communities in  River state, Nigeria. Two hundred and fourteen respondents completed a self-report measure of financial stress, farming insecurity, and burnout. Two hypotheses were tested using data from the respondents. Multiple regression was performed on the data, and the result demonstrated a statistically significant effect of financial stress (?=186) and farming insecurity (?=167) on farmers' burnout. An observation of the R2 indicated that the predictor variables explained about 28.8% of the variation in farmer burnout. The result has implications for developing agricultural output and food security.
许多因素,包括倦怠的心理状况,持续威胁着尼日利亚的当代农业生态系统。本研究调查了来自尼日利亚河州不同农业社区的农民样本中基于财务压力和农业不安全感的农民倦怠。214名受访者完成了一份关于经济压力、农业不安全感和职业倦怠的自我报告。使用受访者的数据对两个假设进行了检验。对数据进行多元回归分析,结果显示经济压力(?=186)和农业不安全感(?=167)对农民职业倦怠的影响具有统计学意义。对R2的观察表明,预测变量解释了28.8%的农民职业倦怠变异。这一结果对发展农业产出和粮食安全具有启示意义。

Diversity of Induced M1V4 Mutant Population of Cassava (Mahinot Esculanta Crantz) 木薯M1V4突变体诱导群体的多样性
M. Kinyua, H. Okwaro
ABSTRACTCassava owns a small genome (about 770 Mb), it is considered as an allopolyploid with a high level of heterozygosity characteristics which severely hamper the speed and ease of introgressing useful genes in cassava. Mutation techniques form a classical procedure of development of variation in crops like cassava while genetic markers can be used to reveal genetic variation in the germplasm. This study was undertaken to determine the genetic relatedness of mutagenised cassava early generation populations through phenotypic and genetic marker procedures. Diversity of mutagenised population of cassava at M1V4 generation was examined at seedling stage in the greenhouse and at adult stage in the field through checking phenotypic and genetic traits. Plant height, number of lobes on leaves, petiole colour, number of nodes per stem and gel separation of PCR products developed from SSR markers differed significantly between selected putative mutants as well as in comparison with parent line. For example plant height of the 10 selected mutants ranged from 16 cm to 113cm where the parent grew to 24.33 cm while the number of nodes ranged from 11 to 24 with the parent having 13 nodes. Diversity of the mutant lines was demonstrated and further studies can be undertaken to quantify the variation for breeding and production of cassava.   
摘要木薯基因组较小(约770 Mb),被认为是一种具有高杂合性的异源多倍体,严重阻碍了木薯有用基因渗入的速度和方便性。突变技术形成了木薯等作物变异开发的经典程序,而遗传标记可以用来揭示种质中的遗传变异。本研究旨在通过表型和遗传标记程序确定诱变木薯早期种群的遗传相关性。通过表型和遗传性状的检测,在温室育苗期和田间成虫期对M1V4代木薯诱变群体的多样性进行了检测。所选突变体的株高、叶上裂片数、叶柄颜色、每茎节数和PCR产物凝胶分离度与亲本相比存在显著差异。例如,10个突变体株高为16 ~ 113cm,亲本株高为24.33 cm;节数为11 ~ 24个,亲本株高13个。突变系的多样性已得到证实,可以进行进一步的研究,以量化木薯育种和生产的变异。

Analysis of Land Use and Land Cover Changes in Ikot Abasi coastal Area from 1986-2016, Southern Nigeria, Using Landsat TM and ETM+ Images and GIS 基于Landsat TM、ETM+影像和GIS的尼日利亚南部Ikot Abasi沿海地区1986-2016年土地利用和土地覆盖变化分析
Iberedem E. Uko, R. Offiong
Ikot Abasi coastal area in Southern Nigeria, have witnessed enormous human activities which include commercial agriculture, industrial activities and urban development over the decades. Due to increasing land use in different dimensions the land cover in the area has been affected. This necessitated the gathering of land use and land cover statistically-based information which is the basis for monitoring and planning of sustainable coastal area management. This study was carried to quantitatively describe changes of land use and land cover in Ikot Abasi coast, Akwa Ibom State, from 1986 to 2016 using Landsat TM and ETM+ of the area, 1986 and 2013; and to carry out change detection in land cover between 1986-2016 in the study area. Image processing and change detection analysis were done through image interpretation processes using Erdas Imagine 9.2 software, and image Minus Algorithm of the mathematical Toolbox within ArcGIS 9.2 software respectively. Statistics indicated that out of 32,452.91ha area of land cover in 1986, the portion of land cover that has changed between 1986-2016 stood at 19,094.84ha (57.96%), while the portion of land cover that remain unchanged within that period was only 13,849.59ha (42.03%). With increasing human activities, more hectares of land cover are anticipated to be reduced in coming years. The study therefore, recommended sustainable agricultural practices such as bush fallowing, non-bush burning practice and selective tree cutting and implementation of development that is ecologically sustainable.
在尼日利亚南部沿海地区,数十年来见证了大量的人类活动,包括商业农业、工业活动和城市发展。由于不同尺度土地利用的增加,该地区的土地覆盖受到了影响。这就需要收集以统计为基础的土地利用和土地覆盖资料,这些资料是监测和规划可持续沿海地区管理的基础。利用1986年和2013年的Landsat TM和ETM+数据,定量描述了阿夸伊博姆州Ikot Abasi海岸1986 - 2016年土地利用和土地覆盖的变化;并对研究区1986-2016年土地覆盖变化进行检测。图像处理和变化检测分析分别使用Erdas Imagine 9.2软件和ArcGIS 9.2软件中的数学工具箱中的图像减算法进行图像判读处理。统计表明,1986年3242.91 ha的土地覆盖面积中,1986-2016年间发生变化的土地覆盖面积为19094.84 ha(57.96%),而同期保持不变的土地覆盖面积仅为13849.59 ha(42.03%)。随着人类活动的增加,预计未来几年将有更多公顷的土地覆盖面积减少。因此,该研究建议采取可持续的农业做法,如丛林休耕、非丛林焚烧和选择性砍伐树木,并实施生态可持续发展。

Incidence of Predators and Anthropogenic Activities Affecting Beekeeping in Nigeria 尼日利亚影响养蜂业的捕食者发生率和人为活动
Lawal A. A., M. S., Oyerinde A. A.
This study evaluated the incidence of predators and anthropogenic activities affecting beekeeping in Nigeria. Questionnaires were administered in Oyo, Ogun and Osun States in the Forest Vegetation and Kaduna, Niger and Kano States in the Savanah vegetation zones of Nigeria. Data obtained were analyzed with parametric statistical tool of mean. The result showed that the largest populations of beekeepers were Bachelor Degree and National Certificate in Education NCE holders (25.0% each), MSc (8%), National Diploma ND (8%) and Postgraduate Diploma PGD (9%).  Assessment of human activities that were harmful to beekeeping identified by respondents in the forest vegetation zones revealed indiscriminate use of pesticide (16.67%), theft (33.33%) and herdsmen activity (cattle rearing) (31.82%) while savannah vegetation zones had the following record, indiscriminate use of pesticide (25.00%), theft (35.33%) and herdsmen activity (35.71%). Avoidance of scattering honeybee (Apis mellifera L.) combs around the apiary was found as the most effective method in preventing spread of insect pests. Other methods include: hive sanitation, hive positioning, handpicking of insects, the use of spent engine oil, regular weeding, fencing of apiary and use of bee pen. The hives painted with green coloured paint was reported by respondent to control wasp, spider, termites and lesser wax moth. Beekeepers reported weeding as the most effective method used in controlling predators as it was noted that apiaries regularly weeded controlled the following predators with their respective incidence level: rat (8.33%), snake (12.50%), toad (29.7%), frog (20.83%) and ghecko (37.50%) while the most significant was lizard incidence which was 54.17%. Report from respondents on traditional methods to detect apiary problems categorized into predator and human activities include: decreasing size of colony, majority of bees staying outside the hive, sighting of pests in the apiary and abscondment of bees while human interference was noticed with dead bees found in and outside the hive, inactive bees, trace of burnt grasses and shrubs in the apiary and felled hives from stands.
本研究评估了尼日利亚养蜂业的捕食者和人为活动的发生率。在森林植被的奥约州、奥贡州和奥孙州以及尼日利亚萨凡纳植被带的卡杜纳州、尼日尔州和卡诺州进行了问卷调查。采用参数化均值统计工具对所得数据进行分析。结果表明,养蜂人以学士学位和国家教育证书(各占25.0%)、硕士(8%)、国家文凭(8%)和研究生文凭(9%)居多。森林植被带对养蜂有害的人类活动评价主要为滥用农药(16.67%)、盗窃(33.33%)和牧民(养牛)活动(31.82%),草原植被带主要为滥用农药(25.00%)、盗窃(35.33%)和牧民活动(35.71%)。避免蜜蜂在蜂房周围散布蜂巢是防止害虫传播的最有效方法。其他方法包括:蜂箱卫生,蜂箱定位,手工采摘昆虫,使用废机油,定期除草,围栏蜂房和使用蜂笼。被访者报告将蜂箱涂成绿色以防治黄蜂、蜘蛛、白蚁和小蜡蛾。养蜂人认为除草是控制捕食者最有效的方法,因为养蜂场定期除草对捕食者的控制程度分别为:大鼠(8.33%)、蛇(12.50%)、蟾蜍(29.7%)、青蛙(20.83%)和壁虎(37.50%),而蜥蜴的发生率最高,为54.17%。从应答者的报告中可以发现蜂房问题的传统方法,这些问题分为捕食者和人类活动,包括:蜂群规模缩小,大多数蜜蜂呆在蜂房外,在蜂房内发现害虫,蜜蜂潜逃,而在蜂房内外发现死蜜蜂,蜜蜂不活跃,在蜂房中发现烧焦的草和灌木的痕迹,以及从林分上砍伐的蜂房。

Household Energy Choice for Cooking Fuel and Underlying Circumstances in Non-Formal Urban Settlements in Kenya 肯尼亚非正规城市住区家庭烹饪燃料的能源选择及其基本情况
Dan Oduor Oluoch, G. Nyamasyo
This study investigated the choice of cooking fuel and underlying circumstances in Kibra slums in Nairobi County, Kenya. The study focused on various factors that influence household choice of cooking fuel and those which could keep household away from using other cooking fuels in non-formal settlements areas in the urban set-up. The study was both quantitative and qualitative and used questionnaires and observation schedules to collect data among targeted households. The findings suggest that various factors play crucial roles in determining household choice of improved fuel for cooking but most dominant factors were; time spent to cook a meal, ease of lighting, affordability, availability of fuel and its storage. The study also realized that lack of sufficient income has little influence on people to adopt or reject improved fuels. The paper argues that more data and necessary information need to be provided on the merits and demerits of various types of improved cooking fuel to the household in the slums and the its environs to enable the residents make better choices. The findings of this study indicated that for fuel choice at various household levels, it is still a challenge as some of the households targeted did not have any good reason why they use their preferred fuel type and have no much knowledge on any dangers associated with their cooking fuel choices apart from when they witness an incidence or incidence which could be considered as dangerous.
本研究调查了肯尼亚内罗毕县基布拉贫民窟烹饪燃料的选择和基本情况。这项研究的重点是影响家庭选择烹饪燃料的各种因素,以及那些可能使家庭在城市结构中的非正规住区地区不使用其他烹饪燃料的因素。本研究采用定量和定性相结合的研究方法,采用问卷调查和观察表的方式对目标家庭进行数据收集。研究结果表明,各种因素在决定家庭选择改进的烹饪燃料方面起着至关重要的作用,但最主要的因素是;做饭的时间,照明的便利性,价格的可承受性,燃料的可用性及其储存。该研究还认识到,缺乏足够的收入对人们采用或拒绝改进燃料的影响很小。本文认为,需要向贫民窟及其周边地区的家庭提供更多关于各种改良烹饪燃料的优缺点的数据和必要信息,以使居民做出更好的选择。这项研究的结果表明,对于不同家庭级别的燃料选择,这仍然是一个挑战,因为一些目标家庭没有任何充分的理由为什么他们使用他们喜欢的燃料类型,除了当他们目睹一个或多个可能被认为是危险的事件时,他们对与他们烹饪燃料选择相关的任何危险没有太多的了解。

Trichomonas Vaginalis Infection Among Students of University of Port Harcourt 哈考特港大学学生阴道毛滴虫感染调查
Eze Chinwe N., Edwin Queen Okwuchi
Trichomonas vaginalis is one of the most common curable sexually transmitted disease. Untreated Trichomoniasis in women can cause cervicitis, vaginites and pelvic inflammatory disease. Trichomonas vaginalisis contributes to high risk of cervical cancer in women and HIV in men. This is an institutional based cross- sectional descriptive study conducted among two hundred (200) female students of Delta Hostels, University of Port Harcourt. High vaginal swabs (HVS) and urine samples were collected from consented students and examined for the presence of T. vaginalis under the microscope. A total of 32(16%) were infected and results obtained from HVS showed a prevalence of 32% compared to urine microscopy which no positive sample was detected. Students between the age group 15-25yrs had the highest prevalence of infection 31(17.2%) while the age group 26-35 years had 1(5%). However, the difference was statistically significant. Based on marital status all were single and had 32(16%) prevalence. This study observed a high prevalence of T. Vaginalis and its symptoms among the study population. The study also noted that high vaginal swab microscopy showed better detection sensitivity compared to urine microscopy. The best option for prevention and control is to educate students on personal hygiene and safe sex practice.
阴道毛滴虫是最常见的可治愈性传播疾病之一。未经治疗的女性滴虫病可引起宫颈炎、阴道炎和盆腔炎。阴道毛滴虫是女性患宫颈癌和男性感染艾滋病毒的高危因素。这是一项基于机构的横断面描述性研究,在哈考特港大学三角洲旅舍的200名女学生中进行。收集同意的学生的阴道拭子(HVS)和尿液样本,并在显微镜下检查阴道绦虫的存在。共有32例(16%)感染,HVS结果显示,与未检测到阳性样本的尿液显微镜相比,患病率为32%。15 ~ 25岁学生感染率最高,为31(17.2%),26 ~ 35岁学生感染率最高,为1(5%)。然而,差异在统计学上是显著的。根据婚姻状况,所有人都是单身,患病率为32%(16%)。本研究观察到阴道绦虫及其症状在研究人群中的高患病率。该研究还指出,与尿液显微镜相比,高阴道拭子显微镜的检测灵敏度更高。预防和控制的最佳选择是对学生进行个人卫生和安全性行为的教育。

Technologies and Sustainable Development: The Cultural Landscapes of the Mediterranean 技术与可持续发展:地中海的文化景观
P. D. Antonio, F. Romano, Vincenzo Nunzio Scalcione, C. D’Antonio
The research aims to highlight how Matera and Pompeii, both UNESCO sites are united by a thousand-year-old history always alive, a heritage made of archaeological remains, paintings, frescoes and intangible goods. Henry Vollam Morton in his book "A traveler in Southern Italy" tells of his visit to Matera in the 60’s, when the Sassi had been abandoned and the population moved for the most part to new neighborhoods, and the city appears to his eyes as "an incredible Pompeii” suspended between past and future, once lived and then abandoned. Today both realities live again thanks to people and institutions who believed in the possibility to restore their life through technology and to resurface enclosed treasures still to be discovered. Pompeii, an ancient Roman colony, although it seems for its history a crystallized city, is always alive and moving thanks to the continuous discoveries that make it one of the most visited destinations with an exponential growth of tourists. Matera was in the last century with the agricultural neighborhood and it is now because like other cities it is into the phase of experimenting with ultra-fast 5g telephony. The 5G experiment has shown that the use of satellite technologies can be of great help to the management and sustainability of cultural landscapes because of support to the development of culture and creativity to the management of visitors, the organization of the tourist destination and the use of cultural heritage and also it enhance and preserves agricultural landscapes and productions, as an expression of the relationship of the community with the natural space.
这项研究旨在突出马泰拉和庞贝这两个联合国教科文组织遗址是如何通过一千年的历史联系在一起的,这是一项由考古遗迹、绘画、壁画和非物质物品组成的遗产。亨利·沃拉姆·莫顿(Henry Vollam Morton)在他的书《意大利南部的旅行者》(A traveler in Southern Italy)中讲述了他在60年代访问马泰拉的经历,当时萨西人已经被遗弃,大部分人都搬到了新的社区,在他看来,这座城市就像一座“令人难以置信的庞贝”,悬浮在过去和未来之间,曾经有人居住,后来又被遗弃了。今天,由于人们和机构相信有可能通过技术恢复他们的生活,并重新发现仍待发现的封闭宝藏,这两个现实又活了起来。庞贝,一个古罗马的殖民地,虽然它在历史上似乎是一个结晶的城市,但由于不断的发现,它总是充满活力和感动,使它成为游客数量呈指数增长的最热门目的地之一。马泰拉在上个世纪是农业区,现在是因为像其他城市一样,它正进入超高速5g电话试验阶段。5G实验表明,卫星技术的使用可以极大地帮助文化景观的管理和可持续性,因为它支持文化和创意的发展,游客的管理,旅游目的地的组织和文化遗产的利用,它还可以增强和保护农业景观和生产,作为社区与自然空间关系的表达。

Changing Pattern of wetlands 湿地格局的变化
P. Pokhrel
The climate of Damak was unhealthy until 1965 A.D. The D. D.T. spray program started here only since 1963. Before 1963 Damak was a home of malaria. This area was dreadful due to the wide due to the wide-presence of poisonous creatures like cobras, Karent (Bungarus lividus), and scorpions. There were a lot of oxbow lake, marshes, quicksand, Holies and swamps inside the tick and dense forests of Damak. It used to be a very difficult situation to the local cowboys to rescue the new foot travelers from hill areas who plunged into the marshes. But Damak, these days, has lost its past physical landscape. The people who visited Damak in the 1960's and 1970's can hardly recognize present Damak. The actual identify of Damak still are the marshes and wetland areas. The name " Damak" itself is derived from the word "Daldal" which means "marshes" in English. In Dhimal language, " Damdam" means "Daldal" meaning " marshy". So from " Damdam" the name " Damak" was derived. This land is hard to plough as it is marshy. The paddy is planted only after digging the field with a spade. So the meaning of Damak reflects "shiny bright". As we step on one part at marshy land (Damdam place), the other part produces shiny fountains. With references to legends and proofs, Damak can be said to have been a marshy area before 1960.
达马克的气候一直到公元1965年都很不健康,而d.d.t喷雾项目直到1963年才开始。1963年以前,达马克是疟疾的发源地。这个地区非常可怕,因为这里到处都是有毒的生物,比如眼镜蛇、卡伦特(Bungarus lividus)和蝎子。在达马克的蜱和茂密的森林里,有很多牛轭湖、沼泽、流沙、圣地和沼泽。对于当地的牛仔来说,解救那些从山区跳入沼泽的新来的徒步旅行者是一件非常困难的事情。但如今,达马克已经失去了过去的自然景观。在20世纪六七十年代访问过达马克的人几乎认不出现在的达马克。达马克的实际身份仍然是沼泽和湿地地区。“达马克”这个名字本身来源于“达达尔”这个词,在英语中是“沼泽”的意思。在迪马尔语中,“Damdam”的意思是“Daldal”,意思是“沼泽”。所以Damdam这个词就衍生出了Damak这个名字。这块地是沼泽,很难耕种。要用铁锹把地挖好,才能种上水稻。所以Damak的意思反映了“闪亮明亮”。当我们踏上沼泽地的一部分(大坝的地方),另一部分产生闪亮的喷泉。根据传说和证据,达马克在1960年之前可以说是一个沼泽地区。

Variation of Social Acceptance: Kashimbila Multipurpose Dam Stakeholders in Focus 社会接受度的变化:喀什比拉多用途水坝利益相关者的焦点
Bala Wunubo, M. Ibrahim
Long ago, rivers have always been sustaining livelihoods through the utilization of different natural resources available in their basins. All over the world, many rivers have been dammed in the spirit of performing various purposes: agricultural irrigation, domestic water supply and power generation or flood control. The World Commission on Dams brought into focus the debate on dam related impacts on local economies, societal cultures, livelihoods security and environmental conservation. The outcome of the World Commission on Dams consultation strongly recommended the involvement of stakeholder groups to address appropriately all issues associated with dams. Therefore, the aim of this study is to examine the variation of social acceptance among different project stakeholders. Mixed research method was adopted for the study and the instruments used for data collection were questionnaire, interview and observation. The respondents were drawn from people living within close fringes of the dam. The estimated population of the area is 247, 657 and the sample size of the research is 269. The participants for interview were identified using a stratified sampling method while those whom questionnaire were administered on were identified using simple random sampling. The responses received suggest that dam project capture attention of dam stakeholder groups, if its components are of interest to the community members. These results indicated that there is an existence of variation among Kashimbila Multipurpose Dam (KMD) stakeholder groups in choosing factors that influenced their acceptance. On this basis it is recommended that project developers should always bear in mind the pressing needs of the affected communities during decision and planning processes of the proposed projects.
很久以前,河流一直通过利用其流域内可用的各种自然资源来维持生计。在世界各地,许多河流都以各种目的筑坝:农业灌溉、家庭供水和发电或防洪。世界水坝委员会使有关水坝对当地经济、社会文化、生计安全和环境保护的影响的辩论成为焦点。世界水坝委员会磋商的结果强烈建议利益相关者团体的参与,以适当地解决与水坝有关的所有问题。因此,本研究的目的是考察不同项目利益相关者之间社会接受度的差异。本研究采用混合研究方法,数据收集工具为问卷调查、访谈和观察。调查对象是居住在大坝周边地区的居民。该地区估计人口为247,657人,研究样本量为269人。访谈对象的识别采用分层抽样法,被调查者的识别采用简单随机抽样法。收到的反馈表明,如果大坝项目的组成部分对社区成员感兴趣,那么大坝项目就会引起大坝利益相关者群体的注意。这些结果表明,喀什比拉多用途大坝利益相关者群体在选择影响其接受度的因素方面存在差异。在此基础上,建议项目发展商在拟定项目的决策和规划过程中,始终牢记受影响社区的迫切需要。
