Onion is one of the important vegetable crops grown by farmers mostly for market purpose. This study focus on explore the challenges and opportunities of small-scale irrigation onion production at fentale district. Samples of 180 onion producer smallholder households were selected through multi-stage random sampling from the three kebeles of Fentale district. Sources of data were both the primary and secondary sources. The primary quantitative data were collected through Interview schedule while the qualitative were collected by FGD and KIIs methods. The data analysis methods also encompassed both quantitative and qualitative. Descriptive statistics (percentage) were employed to analysis quantitative data while qualitative data were analysed by narrations and interpreting the meaning of words. The result of the descriptive statistic reveals that the high cost of inputs, fluctuation in irrigation access, disease and pest, the input supply shortage, high labour cost, flood problem and informal sources of seed were the challenges of onion production at the study area. Besides the high income gained from onion, access to irrigation, good weather condition and the high yield of onion from a small plot were the major opportunities to produce onion at the area. Finally, the researcher recommended that the Government organizations and other responsible bodies should ensure the equal distribution of irrigation water for both upper and lower streams, and strengthen inputs supply chains.
洋葱是农民种植的重要蔬菜作物之一,主要用于市场。本研究的重点是探讨芬泰尔地区小规模灌溉洋葱生产的挑战和机遇。采用多阶段随机抽样的方法,从芬塔莱区3个乡镇抽取180户洋葱生产小农样本。数据来源包括主要来源和次要来源。主要定量资料采用访谈法收集,定性资料采用FGD和KIIs法收集。数据分析方法也包括定量和定性两方面。定量数据采用描述性统计(百分数)进行分析,定性数据采用叙述和释义进行分析。描述性统计结果表明,投入成本高、灌溉渠道波动、病虫害、投入供应短缺、劳动力成本高、洪水问题和种子来源不正规是研究地区洋葱生产面临的挑战。除了洋葱的高收入外,获得灌溉、良好的天气条件和小块洋葱的高产量是该地区生产洋葱的主要机会。最后,研究人员建议,政府组织和其他负责机构应确保上下游灌溉用水的平等分配,并加强投入物供应链。

We investigated the accumulation of iron fillings in corn flour in the Tamale Metropolis using a permanent magnet. We also assessed the metal accumulation in food delicacies and the possible metal concentration in consumers. We then categorised the food vendors in the Metropolis into domestic, ‘low class’ and ‘high class’ commercial vendors. The results revealed that corn flour milled with new pair of plates is likely to contain 1.5 folds Fe than flour milled with old pair of plates. Furthermore, wet milling is the safer choice for producing corn flour than dry milling due to its low metal concentration (mg/g). Nonetheless, there was no trace of Fe in the porridge samples from the commercial vendors yet the samples from households had the largest metal accumulation and metal concentration. This indicates that consuming koko prepared at home will lead to more (≈ 1.20mg/g) metal concentration in the body. Incidentally, there was no metal accumulation and no metal concentration from any of the ‘high class’ commercial TZ vendors due to sieving, demonstrating that they offer the best choice for TZ consumption. Even so, the worse choice for TZ consumption came from the ‘low class’ commercial TZ vendors due to lack of sieving. As such, the worst meal preference is to eat 3-square (breakfast, lunch and supper) meals of banku prepared at home. Yet, the best meal preferences are: either eat 3-square meals of TZ from ‘high class’ commercial TZ vendors; or take 3-square meals of porridge (koko) from ‘high class’ commercial porridge vendors; or eat 3-square meals combination of TZ and porridge (Koko) from the ‘high class’ commercial vendors. Results of the study will influence responsible ‘consumption and production’ of food (a Sustainable Development Goal; SDG 12) in order to erase hunger (SDG 2). It will also trigger healthier eating habits (meal preferences) to boost and sustain the health and well-being of individuals (SDG 3).
我们用永磁体研究了玉米面粉中铁填料的积累。我们还评估了食品中金属的积累和消费者中可能存在的金属浓度。然后,我们将大都市的食品供应商分为国内、“低级”和“高级”商业供应商。结果表明,新板磨玉米粉的铁含量可能是旧板磨玉米粉的1.5倍。此外,湿法磨粉比干法磨粉更安全,因为湿法磨粉的金属浓度(mg/g)较低。尽管如此,来自商业供应商的粥样中没有铁的痕迹,但来自家庭的样品中金属积累和金属浓度最大。这表明,食用在家制作的可可会导致体内金属浓度增加(≈1.20mg/g)。顺便说一句,由于筛分,没有金属积累,也没有来自任何“高级”商业TZ供应商的金属浓度,这表明他们为TZ消费提供了最佳选择。即便如此,由于缺乏筛分,较差的TZ消费选择来自“低级”商业TZ供应商。因此,最糟糕的饮食偏好是吃在家准备的三顿饭(早餐,午餐和晚餐)。然而,最好的饮食偏好是:要么吃“高级”商业TZ供应商提供的3平方顿TZ;或者从“高级”商业粥摊贩那里买一份3平方顿的粥(koko);或者从“高级”商业供应商那里吃三顿TZ和粥(Koko)。研究结果将影响负责任的粮食“消费和生产”(可持续发展目标;可持续发展目标12),以消除饥饿(可持续发展目标2)。它还将引发更健康的饮食习惯(膳食偏好),以促进和维持个人的健康和福祉(可持续发展目标3)。

Agricultural inputs have crucial role to deliver increased productivity and sustained agricultural growth in an economy. However, adequate empirical research is not available related to effects of agricultural inputs use on agricultural productivity in Nepalese context. Thus, empirical study was conducted so as to reveal the effects of agricultural inputs use in agricultural production sector. This study utilized time series data of 30 years (1990 to 2019) retrieved from various secondary data sources of agricultural input supply in Nepal. Then, data obtained were processed and analyzed in two ways: First, Compound Annual Growth Rate (CAGR) of different agricultural inputs were estimated using Log-Lin regression model. Second, the parameters estimates of Cobb-Douglas regression analysis was obtained taking Agricultural GDP as the dependent variable and independent variables viz. cultivated area, irrigated area, population engaged in agriculture, fertilizer consumption, pesticides application, improved seeds used and government expenditure. The results depicted that growth rate of various agricultural inputs use had raised significantly and was in increasing trend during the study period. Furthermore, cultivated area, irrigated area and pesticides application were found statistically significant and had significant impact on growth of agricultural GDP (Gross Domestic Product).
农业投入品在提高生产力和促进农业持续增长方面发挥着至关重要的作用。然而,关于尼泊尔农业投入物使用对农业生产力的影响,还没有充分的实证研究。因此,本文进行了实证研究,以揭示农业投入物在农业生产部门使用的影响。本研究利用了从尼泊尔农业投入供应的各种二手数据源中检索的30年(1990年至2019年)时间序列数据。然后,对数据进行两方面的处理和分析:首先,利用Log-Lin回归模型估算不同农业投入品的复合年增长率(CAGR)。其次,以农业GDP为因变量,以耕地面积、灌溉面积、从事农业的人口、化肥用量、农药用量、良种用量和政府支出为自变量,得到Cobb-Douglas回归分析的参数估计。结果表明:研究期间,各类农业投入品的使用增长率显著提高,并呈增加趋势。耕地面积、灌溉面积和农药施用量对农业GDP的增长具有显著的统计学意义。

The activity was conducted for two consecutive years, 2019 and 2020 cropping season at Ambo and Dandi districts of West Showa Zone with the objective to evaluate for grain yield, yield related traits and farmers’ perception or preference and the performance of improved teff variety along with recommended package. Sites were selected based on teff production potential of the area. Two districts and three PAs from each district and eighteen target farmers were purposively selected on the ground that they are the leading producer of teff in the area. Training was given for farmers, Development Agents and experts on production of improved teff technologies from site selection up to postharvest practices of improved teff variety. Quantitative data such as yield data was collected and analysed using SPSS, whereas farmers feedback were analysed qualitatively. Recommended seed and fertilizer rate were used for the demonstration trial establishment. According to the result of Dagim variety, mean grain yield 18.79 qt/he and 25.51 qt/he were recorded in Ambo and dendi districts respectively. Thus, Dagim variety is recommended for further scaling up activities at Ambo and Dendi districts taking into consideration of its productivity. Farmers of those areas should use the variety in order to increases their teff production and enhance their income from teff.
该活动于2019年和2020年种植季连续两年在西昭和安博区和丹地区进行,目的是评估粮食产量、产量相关性状和农民的感知或偏好,以及改良的苔麸品种的表现和推荐包装。地点的选择是基于该地区的苔麸生产潜力。有目的地选择了两个区和每个区3个保护区和18个目标农民,理由是他们是该地区苔麸的主要生产者。为农民、发展机构和专家提供了关于改良teff技术生产的培训,从场地选择到改良teff品种的收获后做法。利用SPSS软件收集和分析产量等定量数据,对农民反馈进行定性分析。示范试验设置采用推荐种肥率。根据Dagim品种的结果,Ambo和dendi地区的平均产量分别为18.79 qt/he和25.51 qt/he。因此,考虑到其生产力,建议在Ambo和Dendi地区进一步扩大Dagim品种的活动。这些地区的农民应该使用该品种,以增加他们的苔麸产量并增加他们的苔麸收入。

The agricultural sector continues to be the backbone of the Moroccan’s economy, employing 38% of the active working population and contributing to 13% of Gross Domestic Product (GDP). However, Moroccan agriculture is subject to multiple constraints, including volatility due to climatic conditions which continue to condition the economic performance of the country as a whole, despite the decrease in the share of agriculture in the sectoral composition. The main objective of this study is to econometrically explore the causality nexus between agriculture and GDP in Morocco, especially since the sector has benefited from new development strategies. Using Moroccan time series over the period 1980 to 2017, the paper employed the Granger causality based on the vector autoregressive model (VAR) in a dynamic multivariate framework, using five macroeconomic variables: GDP per capita, agricultural GDP, investment rate, money supply, and trade openness. The empirical results from the analysis detect the presence of bidirectional Granger causality between agriculture and GDP, implying a feedback relationship, and some unidirectional causal relationships involving the other macroeconomic variables used in the VAR model. The findings have important policy implications for the government to establish effective agricultural strategies, in particular with the inauguration of the new agricultural strategy «Green Generation» in 2020.
农业仍然是摩洛哥经济的支柱,雇佣了38%的劳动人口,贡献了13%的国内生产总值(GDP)。然而,摩洛哥农业受到多种制约,包括气候条件的波动,尽管农业在部门构成中的份额有所下降,但气候条件继续制约着整个国家的经济表现。本研究的主要目的是用计量经济学方法探讨摩洛哥农业与GDP之间的因果关系,特别是因为该部门受益于新的发展战略。本文以1980 - 2017年摩洛哥时间序列为研究对象,采用人均GDP、农业GDP、投资率、货币供应量和贸易开放度5个宏观经济变量,在动态多变量框架下采用基于向量自回归模型(VAR)的格兰杰因果关系。分析的实证结果发现农业与GDP之间存在双向格兰杰因果关系,这意味着一种反馈关系,以及涉及VAR模型中使用的其他宏观经济变量的一些单向因果关系。研究结果对政府制定有效的农业战略具有重要的政策意义,特别是随着2020年新农业战略“绿色一代”的启动。

This study is conducted to measure the effects of climate responsive variables on agricultural production rate in Bangladesh. Agriculture production is affected by the climate changes and natural disasters that cause farmers enormous financial losses. The study focused on the application of fuzzy logic to find out the effect of climate changes on the agricultural production of Bangladesh. The objective of the study is to see the proposed fuzzy system will aid farmers for taking decision of selecting right crop to get the optimal yield. A set of fuzzy rules have been utilized to obtain inference of agriculture production on different linguistic variables. Altered combination of climate variables like temperature, weather disasters, water availability, monsoon level, diseases, species extinction and deforestation are considered as fuzzy linguistic variables generated through sets of different fuzzy rules and applied to estimate agriculture production rate. Findings show that as temperature and weather disaster increases to its highest level the agriculture production reduces to its lowest level. Furthermore, temperature and water availability has a homogeneous effect on agriculture production which indicates that the effects of increased temperature are balanced by the supply of available water. The effects of temperature and monsoon level to agriculture production indicate high precipitation due to monsoon level damages agricultural production. Moderate temperature with pure water availability resulted from moderate monsoon level produces medium agriculture production. It was found that the minimum spread of diseases can produce moderate level of agriculture production. Nonetheless, species extinction has a long term effect on production and deforestation has an immediate effect on agriculture production. In conclusion, climate variables like weather disaster, deforestation, spread of disease, species extinction damage and reduce the agricultural production rate. The study demonstrates the application of fuzzy logic to examine the impact of climate change on the agriculture production in Bangladesh.
本研究旨在测量气候响应变量对孟加拉国农业生产率的影响。农业生产受到气候变化和自然灾害的影响,给农民造成巨大的经济损失。研究的重点是应用模糊逻辑找出气候变化对孟加拉国农业生产的影响。研究的目的是看到所提出的模糊系统将帮助农民选择合适的作物,以获得最优产量的决策。利用一组模糊规则对不同语言变量进行农业生产推理。气候变量如温度、天气灾害、水资源供应、季风水平、疾病、物种灭绝和森林砍伐的改变组合被认为是通过不同的模糊规则集产生的模糊语言变量,并应用于估计农业生产率。研究结果表明,随着温度和天气灾害增加到最高水平,农业生产下降到最低水平。此外,温度和水的可用性对农业生产的影响是均匀的,这表明温度升高的影响被可用水的供应所平衡。温度和季风水平对农业生产的影响表明,季风水平导致的高降水破坏了农业生产。温和的温度和纯水供应导致适度的季风水平产生中等的农业生产。研究发现,最小的病害传播可以产生中等水平的农业生产。然而,物种灭绝对生产有长期影响,而森林砍伐对农业生产有直接影响。总之,气候变量如天气灾害、森林砍伐、疾病传播、物种灭绝破坏和降低农业生产率。该研究展示了模糊逻辑的应用,以考察气候变化对孟加拉国农业生产的影响。

Agriculture production is affected by the climate changes and natural disasters that cause farmers enormous financial losses. The study focused on the application of fuzzy logic to find out the effect of climate changes on the agricultural production of Bangladesh. The objective of the study is to see the proposed fuzzy system will aid farmers for taking decision of selecting right crop to get the optimal yield. A set of fuzzy rules have been utilized to obtain inference of agriculture production on different linguistic variables. Altered combination of climate variables like temperature, weather disasters, water availability, monsoon level, diseases, species extinction and deforestation are considered as fuzzy linguistic variables generated through sets of different fuzzy rules and applied to estimate agriculture production rate. Findings show that as temperature and weather disaster increases to its highest level the agriculture production reduces to its lowest level. Furthermore, temperature and water availability has a homogeneous effect on agriculture production which indicates that the effects of increased temperature are balanced by the supply of available water. The effects of temperature and monsoon level to agriculture production indicate high precipitation due to monsoon level damages agricultural production. Moderate temperature with pure water availability resulted from moderate monsoon level produces medium agriculture production. It was found that the minimum spread of diseases can produce moderate level of agriculture production. Nonetheless, species extinction has a long term effect on production and deforestation has an immediate effect on agriculture production.

Malian economy is largely based on agriculture, with mango being one of the country's main agricultural exports. The Koulikoro District is one of the main mango production areas in Mali. The sector is subject to numerous challenges, including vulnerability to rainfall variability. The objective of this study was to document the vulnerability of orchards, particularly those based on the Kent and Keitt varieties, in relation to cultivation practices. The approach used to document this issue was based on surveys and interviews with mango farmers of the Kent and Keitt varieties, to identify cultivation practices and the origins of the vulnerability of orchards to rainfall variability in the district. The results show that mango plantations are mainly managed by young, illiterate people, whose age range is 41-46 years. The orchards are small, with areas ranging from 0.25 ha to 3.00 ha, half of which are located on gravelly soils. Women are very poorly represented (6.52% of the sample) in this production activity. Mango seedlings are generally planted during the rainy season, with a high vegetative recovery rate at the start, but a very low survival rate in the months and years following the vegetative recovery. Water sources are traditional wells and streams (temporary and permanent). Manual watering is practiced by more than 80% of farmers. To conserve soil moisture, farmers mulch with or without basins under the mango trees. The lack of technical assistance and rainfall are the major constraints identified. Traditional water sources, primitive watering methods and poor moisture conservation techniques are factors that increase the vulnerability of orchards to rainfall variability.
马里经济主要以农业为基础,芒果是该国主要的农产品出口产品之一。库利科罗区是马里主要的芒果产区之一。该部门面临着许多挑战,包括易受降雨变化的影响。本研究的目的是记录果园,特别是那些基于肯特和基特品种的果园,在种植实践方面的脆弱性。用于记录这一问题的方法是基于对肯特和基特品种芒果种植者的调查和访谈,以确定种植方法和果园易受该地区降雨变化影响的根源。结果表明,芒果种植园主要由年龄在41-46岁之间的年轻文盲管理。果园很小,面积从0.25公顷到3.00公顷不等,其中一半位于砾石土壤上。妇女在这一生产活动中的代表性非常低(占样本的6.52%)。芒果幼苗一般在雨季种植,开始时营养恢复率很高,但在营养恢复后的几个月和几年中成活率很低。水源是传统的水井和溪流(临时的和永久的)。80%以上的农民都采用人工灌溉。为了保持土壤水分,农民在芒果树下用或不用盆覆盖。所查明的主要制约因素是缺乏技术援助和降雨。传统的水源、原始的灌溉方法和较差的保湿技术是增加果园对降雨变化脆弱性的因素。
