thermodynamic and economic evaluation of co2 refrigeration systems

Many countries are encountering serious problems of scarcity of natural resources as well as soil erosion and degradation. Agroforestry is being promoted as a more appropriate land use system than monocropping practices for smallholders worldwide. Unfortunately, detailed studies on the sustainability of different land use systems are limited. As land has started to deteriorate, many farmers are turning to traditional agricultural systems. The researcher studied three traditional agroforestry practices in Yemen and their role in maintaining soil fertility and productivity in the short and long term as compared with monoculture. SCUAF software was used to determine the impact of different farming systems on soil properties, and the outputs of the simulation were used to determine the productivity of each system. This book is divided into 8 chapters which present fascinating information on the importance of agroforestry in soil conservation, as well as the profitability of farms. It is an invaluable book for researchers, policy makers, and all those interested in the sustainable management of farms, the achievement of food security, and the alleviation of poverty.
