POSSESSION OF AGRICULTURAL LAND (AGRICULTURAL HOLDING) AS A PARAMETER OF AGRICULTURAL ACTIVITY [PDF]

open access: yesZeszyty Naukowe Wyższej Szkoły Humanitas Zarządzanie, 2019
The purpose of the article is to show that the concept of agricultural activity, like the concept of an agricultural producer conducting it, can be characterized by reference to the possession of agricultural land (agricultural holding) in the meaning of civil law.

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming

open access: yesAdvanced Science, EarlyView.
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...
