Agroecology represents one of the main alternatives in Uruguay and other countries to production models generated by the green revolution. In Uruguay, agroecology has become more popular but is still marginal, despite the existence of a national plan (Law 19717) that promotes it. The implementation of agroecology needs a knowledge generation system to support it; however, research on agroecological transition processes is still incipient. The objective of this work is to improve the knowledge of the family livestock farmers’ decision-making processes through the study of socio-productive practices, and consequently contribute to actions and public policies closer to farmers. The practices highlighted in this work allowed a typology elaboration that represents the possible pathways through which family livestock farmers move towards agroecology. The agroecological transition is conjugated in plural.
在乌拉圭和其他国家,生态农业是替代绿色革命产生的生产模式的主要选择之一。在乌拉圭,生态农业越来越受欢迎,但仍然处于边缘地位,尽管存在一项促进它的国家计划(1977年法律)。生态农业的实施需要知识生成系统的支持;然而,对农业生态转型过程的研究尚处于起步阶段。这项工作的目标是通过对社会生产实践的研究,提高对家庭畜牧农民决策过程的认识,从而促进更贴近农民的行动和公共政策。在这项工作中强调的实践允许类型学阐述,代表了家庭畜牧业农民走向农业生态学的可能途径。农业生态转型是复数形式。

Bacterial canker and the premature death of young stone fruit trees, caused by different members of the Pseudomonas syringae ( Ps ) complex, affects commercially grown apricot orchards. Altogether, 70% of samples of mother apricot tree scion varieties ( Prunus armeniaca L.) from different European localities consisted of Pseudomonas strains which are highly pathogenic to detached apricot twigs in the pathogenicity test. These strains were attributed to phylogroup PG02 and PG03, and rpoD sequencing confirmed a similarity to strains of Pseudomonas syringae pv. syringae and Pseudomonas amygdali pv. morsprunorum race 1 known to be pathogenic to apricot, respectively.

In this article, preparation types of Tarhana according to the regions in Turkey and 9 important varieties are tried to be explained. Main materials; yogurt or Kurut, wheat flour or cracked wheat, chickpeas, lentils, garlic, tomatoes, mint, red pepper, green pepper, salt and butter. If desired, sour plum, cranberry fruit, tarhana herb, dried meat and sugar beet, onion, garlic, tomato paste, hot pepper can also be added. It is widely believed that it takes its name from the word ‘Darhane in Turkish’, that is, weak economic power. Tarhana; it is the oldest and well-known soup in Turkish cuisine. There is no region or town in Turkey that does not produce and consume Tarhana. It is a flavored soup with a high nutritive rate and energy, prepared by drying, with a long shelf life. Its material is easily available and serviceable. With these features, it had been a reason for preference among nomadic Turks and has been made developed over time. The spice in Tarhana has an antiseptic and relaxing effect. It is a protein-rich, balanced and healthy food. Those who live in cold climates, rural areas and nomadic life; The slightly spicy one is an ideal food for the elderly and the sick. Southeastern Anatolia region prefers spicy. Tarhana is known throughout the Ottoman geography. It is known and loved in a wide geography such as Anatolia, the Balkans, North Africa and Central Asia. How it is prepared; It varies according to the possibilities, climate, culture of the geography where it is produced and the skill of the person who prepared it. There are varieties such as Sour Tarhana, Sweet Tarhana, Flour Tarhana, Göce Tarhana, Tooth Tarhana, Cranberry Tarhana, Red and White Tarhana. Red Tarhana, Göce Tarhana, Tooth Tarhana and Flour Tarhana are the most common. Its production and consumption is high in the provinces of Uşak, Muğla, Antalya, Isparta, Afyonkarahisar, Edirne, Van, Malatya and Kahramanmaraş. Recently, industrial production for instant soup has been started. However, we do not have numerical information about the amount of production and consumption.
本文根据土耳其的不同地区,对塔哈那的制作类型和9个重要品种进行了阐述。主要材料;酸奶或Kurut,小麦粉或碎小麦,鹰嘴豆,小扁豆,大蒜,西红柿,薄荷,红辣椒,青椒,盐和黄油。如果愿意的话,酸梅、蔓越莓、香草、肉干和甜菜、洋葱、大蒜、番茄酱、辣椒也可以加入。人们普遍认为,它的名字来自“土耳其语中的Darhane”,意思是经济实力薄弱。Tarhana;它是土耳其菜中最古老、最著名的汤。土耳其没有一个地区或城镇不生产和消费塔哈纳。它是一种营养价值高、能量大的调味汤,采用干燥制得,保质期长。它的材料是容易获得和维修。由于这些特点,它一直是游牧突厥人偏爱的原因,并随着时间的推移而发展。塔哈那的香料有杀菌和放松的作用。它是一种富含蛋白质、均衡健康的食物。那些生活在寒冷气候、农村和游牧生活的人;微辣的是老人和病人的理想食物。安纳托利亚东南部地区喜欢吃辣。塔尔哈纳在整个奥斯曼帝国地理中都很有名。它在安纳托利亚、巴尔干半岛、北非和中亚等广泛的地区都很有名,也很受欢迎。它是如何准备的;它根据生产它的可能性、气候、地理文化和准备它的人的技能而变化。有各种各样的Tarhana,如酸Tarhana,甜Tarhana,面粉Tarhana, Göce Tarhana,牙齿Tarhana,蔓越莓Tarhana,红色和白色Tarhana。红色塔哈纳、Göce塔哈纳、牙齿塔哈纳和面粉塔哈纳是最常见的。其产量和消费量在uuriak, Muğla,安塔利亚,Isparta, Afyonkarahisar, Edirne, Van, Malatya和kahramanmaraku等省很高。最近,速溶汤的工业化生产已经开始。然而,我们没有关于生产和消费数量的数字信息。

Climate variability and change is one of the greatest threats facing humanity, with far-reaching and devastating impacts on people, ecosystem services, natural resource-base and the natural environment as a whole. This paper aims to evaluate the impact of rainfall variability on agricultural production in Jakiri Sub-Division of the Northwest Region of Cameroon. Previous studies on the impact of climate on agriculture focused on stakeholder signatures to climate change adaptation to the agrarian sector of the Bui Plateau, which revealed that despites glaring consequences of climate, the Jakiri Council only allocates only 1% of its annual budget for climate action. Data sources for this study included the administration of 211 questionnaires to cover the three agro-ecological zones of Jakiri Sub-Division, rainfall data collected from UNVDA Ndop (lowland zone), National Meteorological Service (mid-altitude zone) and the Oku Wildlife Sanctuary (highland zone). The Rainfall Anomaly Index (RAI) was used in analysing rainfall data. Results revealed that rainfall is reducing as depicted by the increasing trends in RAI. Farmers also perceived that food crop production has been decreasing. Despite these perceptions, some crops like cassava that is drought tolerant has been increasing. Again, rice production at the Wahsi-Ber Plain has been increasing. This calls for the development and production of more drought tolerant food crops to ensure sustainable rural livelihoods.
气候变率和变化是人类面临的最大威胁之一,对人类、生态系统服务、自然资源基础和整个自然环境产生深远和破坏性的影响。本文旨在评估降雨变率对喀麦隆西北地区Jakiri分区农业生产的影响。先前关于气候对农业影响的研究主要集中在布伊高原农业部门适应气候变化的利益相关者签名上,结果表明,尽管气候变化带来了明显的后果,但Jakiri委员会仅将其年度预算的1%用于气候行动。本研究的数据来源包括对Jakiri分区三个农业生态区211份调查问卷的管理,以及从UNVDA Ndop(低地区)、国家气象局(中海拔区)和Oku野生动物保护区(高地区)收集的降雨数据。降雨异常指数(RAI)用于分析降雨资料。结果表明,降水呈减少趋势,RAI呈增加趋势。农民们还认为粮食作物产量一直在下降。尽管存在这些看法,但木薯等耐旱作物的数量一直在增加。同样,瓦西-贝尔平原的稻米产量一直在增加。这就要求开发和生产更耐旱的粮食作物,以确保可持续的农村生计。

Carlos Modesto Martínez Hernández
In the last years we had worked in the use of slow sand filters for the decontamination of biodigesters effluents and the sugar mill oxidation lagoons. The work was carried out with the objective of eliminating the contamination of these effluents located in some sugar mills as: “Carlos Baliño”, “George Washington” and “Melanio Hernández”. The effluents were taken in the central region of Cuba (Santo Domingo, Manacas, Villa Clara and Tuinicú, Sancti Spíritus). The effluents were proven to passing through by the slow sand filter in cascades before different investigated treatments. The effluents were diluted in distilled water in the different proportions: T1 (10%), T2 (25%), T3 (50%), T4 (75%), T5 and T6 (not diluted). In the effluents, they were determined: their physical-chemical and microbiological characteristics, previous and later to passing through by the slow sand filters. In most of the effluents, so much their physical-chemical properties, like as the microbial load a remarkable reduction was obtained; obtaining values which are in accordance with the Cuban norms [1-3]. The slow sand filtration has been broadly used as method to improve the quality of the water in different regions of the planet, due to its simplicity in the operation and to its numerous advantages. It has been demonstrated that the slow sand filters have worked in a successful way in areas so much urban as rural around the world, many of which subsist in a precarious way, allowing improvements as regards public health and in the quality of the inhabitants’ life of these areas, even in it has been evidenced their good operation and the positive impact that generate this type of technologies. In recent investigations [4-10], it has been evaluated the method of slow sand filtration like alternative to obtain not very aggressive effluents of oxidation lagoons to the environment with local materials diminishing costs and offering an alternative before the current conditions of these effluents, which are poured to the means with high value of contamination. Some of these studies, they have referred to the implementation a slow sand filters systems to laboratory scale with the purpose of improving the effluents of oxidation lagoons, and later on to measure certain parameters of the effluents and to compare them with the Cuban norm [1] of residual water and [2] for the use of the residual of the sugar cane industry for to irrigate the sugar cane. In the investigations indexed previously, it has been able to verify that the slow sand filters were a good alternative to improve the quality of the biodigesters effluents, obtaining high percentages of removal of chemical oxygen demand (COD), biological oxygen demand (BOD5), total solids (TS), fecal coliform, total coliform and pseudomonas aeruginosas in recent investigations. On this base, this work had the main purpose of to evaluate the effect of slow sand filters for the improving the sugar mill oxidation lagoon effluents with d
在过去的几年里,我们一直致力于使用慢砂过滤器净化生物消化池废水和糖厂氧化泻湖。开展这项工作的目的是消除位于" Carlos Baliño "、" George Washington "和" Melanio Hernández "等糖厂废水的污染。这些污水取自古巴中部地区(圣多明各、马纳卡斯、维拉克拉拉和Tuinicú、圣蒂Spíritus)。实验证明,在不同的处理方法之前,污水都能通过慢砂级联过滤器。在蒸馏水中按不同比例稀释:T1(10%)、T2(25%)、T3(50%)、T4(75%)、T5和T6(未稀释)。在污水中,测定了它们的物理化学和微生物特性,前后通过慢砂过滤器。在大多数流出物中,它们的物理化学性质,如微生物负荷,都得到了显著的减少;获得符合古巴规范的数值[1-3]。慢速砂滤由于其操作简单和众多优点,已被广泛用于改善地球不同地区的水质。事实证明,在世界各地的城市和农村地区,慢速滤砂机都取得了成功,其中许多地区的生存方式不稳定,从而改善了这些地区的公共卫生和居民的生活质量,甚至在这些地区也证明了它们的良好运行和产生这类技术的积极影响。在最近的调查中[4-10],已经评估了缓慢砂过滤的方法,如替代方法,使用当地材料将氧化泻湖的不太具有腐蚀性的废水排放到环境中,从而降低成本,并在这些废水的现状之前提供了一种替代方法,这些废水被倾倒到具有高污染价值的手段中。其中一些研究,他们提到了在实验室规模上实施慢砂过滤系统,目的是改善氧化泻湖的废水,后来测量废水的某些参数,并将其与古巴标准[1]的残余水进行比较,[2]用于使用甘蔗工业的残余水来灌溉甘蔗。在之前的调查中,已经能够验证慢砂过滤器是改善生物沼池出水质量的良好选择,在最近的调查中获得了很高的化学需氧量(COD)、生物需氧量(BOD5)、总固体(TS)、粪便大肠菌群、总大肠菌群和铜绿假单胞菌的去除率。在此基础上,研究了慢砂滤池对不同稀释率的糖厂氧化泻湖出水的净化效果。因此,本文以一种概括的方式提出了一些已获得的结果:

Relevance: According to the State of World Food and Nutrition Security, more than 820 million people remain hungry and 2 million are moderately or severely food insecure. The search for new raw materials rich in nutrients and present in Brazilian biodiversity is a new challenge, considering that in the current menu, only 30 species are food sources for 95% of the world’s population. It is expected that new advances in research and new cultivation technologies favor the agriculture of new species with potential use as food and input for the pharmaceutical industry. In this context, we consider that the Dioscorea genus with more than 150 native species, and with some species cultivated and used in food, can be better explored as new matrices rich in nutrients for consumption and as an input for the pharmaceutical industry. The cultivation of Dioscorea species, today is developed with outdated technologies and practiced by small farmers and consequently difficult to maintain production and a delicate harvest requiring new research and technologies to increase productivity and in post-harvest operations. Objective: this review aims to provide data on native species of Dioscorea , as a possible ally in the search for efficiency in the agricultural sector, food safety and source of inputs for the pharmaceutical industry. Methodology: it was based on data from scientific publications (2000 and 2020) collected in scientific databases using the keywords: Dioscoreaceae, Dioscorea ; “igname”; “yam” and “cará”. Result: Dioscorea species native to Brazil have chemical diversity, richness of nutrients and other metabolites, justifying their potential use in food and input for the pharmaceutical industry and other possible applications, as we have shown. Conclusion: New research approaches and new technologies applied to the study of native species in Brazil can generate knowledge in fighting hunger and in the search for target molecules that can be commercially exploited, promoting innovation in all sectors and environmental preservation as well as sustainable use.
相关性:根据《世界粮食和营养安全状况》,全球仍有8.2亿多人处于饥饿状态,200万人处于中度或重度粮食不安全状态。考虑到在目前的菜单中,只有30种物种是世界95%人口的食物来源,寻找富含营养和巴西生物多样性的新原材料是一项新的挑战。预计研究的新进展和新的栽培技术有利于培育具有潜在食品和医药工业投入价值的新物种。在此背景下,我们认为薯蓣属有150多种本地物种,其中一些物种被种植和用于食品,可以更好地作为富含营养的新基质用于消费和作为制药工业的投入。如今,薯蓣品种的种植是用过时的技术开发的,由小农进行,因此难以维持生产和精细的收获,需要新的研究和技术来提高生产力和收获后的操作。目的:本综述旨在提供薯蓣本地物种的相关资料,为提高农业部门的效率、食品安全和制药行业的投入来源提供可能的参考。方法:基于科学数据库收集的科学出版物(2000年和2020年)数据,关键词:薯蓣科,薯蓣;“igname”;" yam "和" car "。结果:原产于巴西的薯蓣物种具有化学多样性、丰富的营养物质和其他代谢物,证明了它们在食品和制药工业投入和其他可能应用中的潜在用途,正如我们所展示的那样。结论:应用于巴西本地物种研究的新研究方法和新技术可以为抗击饥饿和寻找可商业化开发的目标分子提供知识,促进所有部门的创新和环境保护以及可持续利用。
