Neglected implications of land-use and land-cover changes on the climate-health nexus

Abstract

Climate change can substantially affect temperature-related mortality and morbidity, especially under high greenhouse gas emission pathways. Achieving the Paris Agreement goals require not only drastic reductions in fossil fuel-based emissions but also land-use and land-cover changes (LULCC), such as reforestation and afforestation. LULCC has been mainly analysed in the context of land-based mitigation and food security. However, growing scientific evidence shows that LULCC can also substantially alter climate through biogeophysical effects. Little is known about the consequential impacts on human health. LULCC-related impact research should broaden its scope by including the human health impacts. LULCC are relevant to several global agendas (i.e., Sustainable Development Goals). Thus, collaboration across research communities and stronger stakeholder engagement are required to address this knowledge gap.

Hydrological responses to the synergistic climate and land-use changes in the upper Lancang river basin

“…The warming trend has favored vegetation growth in Tibetan Plateau over the past decades [6]. Land and climate continuously interact, ending with changes in complex biophysical and biogeochemical processes and human activities in the context of coupled nature-human system [7][8][9][10] Specifically, climate change has triggered land use changes, especially an upward expansion of cropland in the mountain regions [11]. During 1992-2015, the grassland, the primary vegetation cover, in the region declined by 22 621 km 2 ; while the cropland increased by 15 015 km 2 .…”
