概括
尼泊尔的一项新的社区城市化规模显示,城市化增加与减少家庭粮食不安全有关. 农业职业并没有显著改变这种关系,强调了在粮食安全研究中需要细微的城市化措施的需要.
科学领域:
- 粮食安全和营养
- 城市化和发展研究研究.
- 农业经济学 农业经济学
背景情况:
- 城市化对粮食系统和粮食安全产生重大影响,特别是在低收入和中等收入国家.
- 现有的"城市与农村"分类往往是二进制和非标准化的,限制了研究.
- 对城市化对粮食安全影响的细微理解对于政策制定至关重要.
研究的目的:
- 为尼泊尔开发一个新的社区城市化规模.
- 评估社区城市化与家庭粮食安全之间的关联.
- 探索农业职业在尼泊尔农业生态区的改变作用.
主要方法:
- 在尼泊尔的63个社区,对4285个有幼儿的家庭进行了多阶段的调查.
- 社区城市化规模的开发,使用8个领域的因子分析.
- 多层混合效应物流回归分析城市与粮食安全的关联,并根据农业职业对效应的修改.
主要成果:
- 社区城市化得分各不相同,山区和山丘地区的大多数农户报告粮食不安全.
- 社区城市化程度较高与家庭粮食不安全率较低显著相关 (OR:0.82;CI:0.71,0.94).

Key Elements for Plant Nutrition
18.7K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

The Roles of Bacteria and Fungi in Plant Nutrition
35.2K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
