Most countries in the Near East and North Africa saw a steady improvement in food security and nutrition up to the beginning of the decade. Food production was rising and undernourishment and poverty were receding. However, the situation has deteriorated since 2012, largely driven by increasing conflicts and protracted crises as well as water scarcity and climate change.
Emphasis in agricultural research for many years has concen trated on crop production. This emphasis has become more important in recent years with the realization that the population worldwide is outstripping the food supply. There is, however, another side to increasing the availability of the food supply. This simply involves preservation of the harvested crop·for human consumption. The losses incurred in harvesting, handling, transportation, storage and marketing crops have become a greater problem as the distance from the farm to the ultimate consumer increases. In the Western world where modern transportation, storage facilities, and marketing technology are widely used, post-harvest technology requires a large input of energy which increases costs considerably. There fore, losses are more significant and the ability to provide fresh fruits and vegetables, out of season, at reasonable costs will depend on reduced post-harvest losses throughout the marketing chain from the farm gate to the ultimate consumer. The reduction in post-harvest losses depends on proper use of current technology and further developments derived from a broad spectrum of scientific disciplines. Biochemistry, plant physiology, plant pathology, horticulture, agronomy, physics, engineering and agricultural economics, all provide knowledge which has been useful and will be useful in the future for improving post-harvest technol ogy and crop preservation. This volume records the Proceedings of the NATO Advanced Study Institute on Post-Harvest Physiology and Crop Preservation, held at Sounion, Greece, April 28 - May 8, 1981.
"Furnishes exhaustive, single-source coverage of the production and postharvest technology of more than 70 major and minor vegetables grown in tropical, subtropical, and temperate regions throughout the world. Provides comparative data for each vegetable presented. "
Fruits and vegetables, commonly termed as "fresh produce" are an important component of the human diet, as these provide various beneficial and essential health-related compounds. Nevertheless, fresh produce is susceptible to postharvest deterioration and decay along with loss of certain nutrients due to innapropriate storage conditions and lack of standard postharvest technologies. In addition, the short shelf life is considered another major constraint that must be extended after harvest to ensure a wider availability window of the fresh produce for consumers. From this perspective, the use of postharvest approaches is considered imperative to reduce the deterioration of harvested fresh produce in order to extend their storage and shelf life potential on a sustainable basis. Sustainable Postharvest Technologies for Fruits and Vegetables covers various aspects of postharvest technologies with major developments over the recent past and provides a way forward for the future. The sustainable use of various technologies and elicitors could be adapted from farm to fork in order to conserve the eating quality of fresh produce. Therefore, this book covers various sustainable postharvest treatments and technologies that could be considered highly effective for the delay of postharvest senescence and deterioration. Among the various technologies, the use of preharvest treatments, controlled atmosphere, dynamic control atmosphere, modified atmosphere and hypobaric conditions has tremendous potential for the fresh fruits and vegetables industry. In the same way, cold plasma, pulsed light, ultraviolet light, ultrasound technology, nanoemulsions, nano-packaging, electrolyzed water, high pressure processing, ozone gas, irradiations, edible coatings, vacuum packaging and active packaging with slow releasing compounds along with nanotechnology are highly practicable and possesses tremendous potential to be used in the maintenance of overall eating quality and storage life extension of the fresh produce. Key Features: Overviews the major factors affecting postharvest physiology and shelf life potential of fresh produce. Focuses on major sustainable technologies having the potential to maintain postharvest quality and extend shelf life of fruits and vegetables. Describes practical and recent advances of various approaches indispensable for the maintenance of overall eating quality and food safety attainment for fresh produce on a sustainable basis. Covers how quality maintenance and shelf life rely on preharvest practices, nonthermal treatments, storage atmospheres, packaging materials, active packaging, edible packaging, coating application techniques, nanotechnology and ecofriendly plant extracts and natural antagonists.
Africa's Geography presents a comprehensive exploration of the world’s second largest and most culturally diverse continent. Author Benjamin Ofori-Amoah challenges common misconceptions and misrepresentations of Africa from a geographical perspective, harnessing the power of modern geographic mapping technology to explore this unique continent. This text provides thorough coverage of the historical, cultural, economic, and political forces that continue to shape Africa, applying geographic context to relevant past and contemporary issues. Coverage of economic development, climate and biogeography, transportation and communication, manufacturing and commerce, and mining and agriculture provides foundational knowledge of this vast and complex continent. Ideally suited for multiple areas of classroom study, this text offers an effective and flexible pedagogical framework. Coverage of the entirety of Africa enables students to develop a cohesive portrait of the continent as a whole and identify the dynamism of its nations, cultures, and economies. Engaging and accessible narrative strengthens comprehension, while examples of historical and contemporary events increase student interest. Innovative and unique, Africa’s Geography is an essential resource for cross-disciplinary investigation of this fascinating part of the world.
