As urbanization surges in China, particularly in the Harbin–Changchun Urban Agglomeration (HCUA), the delicate balance between land use for production, ecology, and living spaces is increasingly under pressure. Recent research led by Xiaomeng Wang from the College of Earth Sciences at Jilin University delves into these pressing land use conflicts, offering insights that could reshape agricultural strategies in the region.
The study employs the Production–Ecological–Living Space (PELS) theory alongside a Patch-generating Land Use Simulation (PLUS) model to analyze land use dynamics and conflicts from 2000 to 2030. What emerges is a complex picture where agricultural needs clash with urban expansion and ecological preservation. Wang notes, “The competition for land is intensifying, which not only affects agricultural productivity but also has significant implications for ecological health and urban planning.”
One of the key findings indicates that from 2000 to 2020, land use types in the HCUA have been predominantly agricultural and ecological, yet the overall area designated for ecological space has decreased. This trend raises alarms about the sustainability of agricultural practices in the face of mounting urban pressures. The research highlights that absolute conflicts—where living space encroaches on production space—are most severe in the western plains of the region. Here, the agricultural sector might face increasing challenges as urban sprawl continues to encroach on prime farmland.
In terms of future scenarios, the research suggests that under an economic development scenario, land use conflicts could intensify, particularly as living spaces expand at the expense of agricultural and ecological areas. Conversely, the sustainable development goals (SDGs) scenario proposes a more balanced approach, suggesting that with careful planning, it’s possible to maintain agricultural productivity while enhancing ecological integrity.
Wang emphasizes the importance of strategic land use planning, stating, “Our findings underscore the need for a nuanced approach that reconciles agricultural needs with urban development and ecological preservation.” This perspective is crucial for policymakers and agricultural stakeholders who must navigate the complexities of land use in a rapidly changing environment.
The implications for the agriculture sector are profound. Farmers and agribusinesses may need to adapt to a landscape where land availability is increasingly contested. This could mean exploring innovative farming practices, such as vertical farming or agroforestry, which might allow for productive use of land without compromising ecological integrity.
As urban areas continue to expand, the insights gleaned from this research, published in the journal ‘Land’ (translated from Chinese), serve as a vital reference for sustainable land management. The study not only sheds light on the current state of land use conflicts but also provides a framework for future developments in agriculture and urban planning, making it a significant contribution to ongoing discussions about sustainable development in rapidly urbanizing regions.
