Quy mô tích hợp Multi-Phân tích của Agroecosystems: Thay đổi công nghệ và tương thích sinh thái Theo phân tích được trình bày trong chương trước, một sự gia tăng của áp lực nhân khẩu học và bioeconomic trên hành tinh của chúng ta là động lực chính của sự tăng cường sản xuất nông nghiệp ở cấp độ hệ thống canh tác. Đổi lại, một sự tăng cường mạnh mẽ của sản xuất nông nghiệp có thể được liên kết với một sự can thiệp mạnh mẽ hơn về cơ chế tự nhiên của các quy định của hệ sinh. | 10 Multi-Scale Integrated Analysis of Agroecosystems Technological Changes and Ecological Compatibility According to the analysis presented in the previous chapter a general increase ofboth the demographic and bioeconomic pressure on our planet is the main driver of intensification of agricultural production at the farming system level. In turn a dramatic intensification of agricultural production can be associated with a stronger interference on the natural mechanisms of regulation of terrestrial ecosystems that is to a reduced ecological compatibility of the relative techniques of agricultural production. To deal with this problem it is important to first understand the mechanisms through which changes in the socioeconomic structure are translated into a larger interference on terrestrial ecosystems. This is the topic of this chapter. Section studies the interface socioeconomic contextfarming system. At the farm level in fact the selection of production techniques is affected by the typology of boundary conditions faced by the farm. In particular this section focuses on the different mix of technical inputs adopted when operating in different typologies of socioeconomic context. Section deals with the nature of the interference on terrestrial ecosystems associated with agricultural production. A few concepts introduced in Part 2 are used to discuss the possible development of indicators. The interference generated by agriculture can be studied by looking at the intensity of the throughput of appropriated biomass per unit of land area. Changing the metabolic rate of a holarchic system such as a terrestrial ecosystem requires 1 a readjustment of the relative size of its interacting parts 2 a redefinition of the relation among interacting parts and 3 changing the degree of internal congruence between produced and consumed flows associated with its metabolism. When the external interference is too large we can expect a total collapse of the original system
