Abstract

Climate and environment have a significant impact on vegetation growth in terrestrial ecosystems, particularly in mountainous regions like Pamir Mountains in Central Asia where sustainable gross primary production (GPP) and food security is a major societal challenge. Numerous in-situ studies have revealed the influence of one or two environmental factors on vegetation growth, but the maximum significant effect of climatic and environmental factors on GPP over time at a large scale remains unknown. This research explores spatiotemporal patterns of the lagged and cumulative effects of sixteen climate and environmental indicators on GPP from 2015 to 2023 in GBAO Central Asia using the most up to date MOD17H2 GPP product. Results demonstrate an early increase in GPP from winter 2015 to summer 2015, followed by a constant fall until January 2023, after which it begins to increase again. Matter and energy flow are well-combined in the Pamir Mountain ecosystem, where photosynthesis, carbon cycle, climate and environmental conditions, and solar energy conversion into chemical energy all contribute to the overall output known as GPP. This study emphasizes the critical relevance of understanding the legacy effect, namely the cumulative impact of climate and environmental influences on terrestrial ecosystems and propose enhancing GPP by adjusting composition, configuration, and policies to sustain food security.

期刊介绍： Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action. Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers. All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
