The passive hybrid allows for high self-sufficiencies of 84.6% in summer and 25.3% in winter, which are only slightly lower than those of a standard system.
In both scenarios, demand exceeds supply earlier than the comparison scenario - in 2017 for medium self-sufficiency and 2019 for high self-sufficiency.
Both self-sufficiency scenarios result in workforce demand substantially exceeding workforce supply in 2025, by approximately 9,300 doctors for medium self-sufficiency and 15,200 under high self-sufficiency.
It follows that, in spite of a very high self-sufficiency rate, the country imports about 11% of its supply of the aggregate "Cereals and Milk" with only about 90% of its domestic supply coming from the country's own production.
In particular, the differences between metabolic pathways of neuronal and astrocytic networks do not imply the occurrence of lactate exchange between cells, most likely because neurons and astrocytes do possess a relatively high self-sufficiency for both glycolytic and oxidative glucose metabolism (see [ 20] and references therein).
The management effect was primarily caused by lower net imports of fodder and fertilisers to the organic farms and the following higher self-sufficiency in fodder.
The higher self-sufficiency rate needs more arable land.
They found that high rice self-sufficiency rates require a high level of import restriction, but this policy is expected to lead to a lowering of household food consumption.
The third experiment would impose a high grain tariff (GTI) to protect domestic grain producers and thus to encourage a high grain self-sufficiency rate.
At the present, China imposes higher import tariffs for grain products than for other agricultural commodities to maintain a high grain self-sufficiency rate.
Since arable land "Red Line" policy provides a critical point of arable land, the study aims to assess whether this critical points are sufficiency to ensure high grain self-sufficiency rates in long term.
