Cui Q Energy in Agroecosystem 2020 torrent

Textbook in PDF format

Agroecosystem is the unit of agricultural ecosystem study, including all the elements inside this unit. Its unique is as the name defined, human activities are the core of this ecosystem, like other agricultural activities. Relying onwhich, agroecosystem has simpler species and backward energy flow into them
comparing with natural ecosystems.
Since energy is the sources of agriculture products, the analysis and prediction of energy has always been a research focus. This book covers topics about energy demand modeling, energy efficiency analysis, energy use assessment of agroecosystems. Usually researches follow biomass production and fuel trade-offs to analyze energy efficiency of agroecosystems. However, other measurement concepts as exergy have been more and more popular. While analyses of energy efficiency in agroecosystems’ biomass production offer important insights in the context of sustainable land management and biomass production, much of them focused on the energy efficiency of either food or energy provision. Comprehensive analyses at the total agroecosystem level that study long-term change in agroecosystem energetics in the course of the socioecological transition have been addressed in this book. On the other hand, basis topics for agroecosystem research such as land-use change, fertilizer/pesticides risk assessment, adaptation to climate change have been kept evolving with novel methodologies. These methodologies and topics were addressed with detailed case studies in this book
