The Path to Reducing Fresh Produce Losses in Harvest & Post-Harvest

One third of food produced is either lost or wasted. According to FAO, globally there is more loss of food in the supply chain before it reaches markets than due to food waste by consumers. It is to the benefit of all of the stakeholders—farmers, handlers, processors, traders and governments - to work on avoiding harvest and post-harvest losses as a solution to producing food for a growing population.

One of the main challenges facing Ethiopia today is to ensure food security for its highly increasing population growth. Although the country's production is much lower than the national demand, there are high post-harvest food losses. Among several causes at different levels, absence of infrastructure plays a critical role in quantitative and qualitative losses of mainly fruit, vegetable, root and tuber crops. This study was initiated to investigate impact of two different production areas having different road access on qualitative and quantitative loss of potato tuber in extended storage time.

1. Introduction

Quality of fruits and vegetables is a combination of attributes or properties that give them value in terms of human food. Components of quality include appearance, texture, flavor, and nutritive value Table 1. Growers and shippers are concerned that their commodities have good appearance and few visual defects. But to them a useful cultivar of a given commodity must score high on yield, disease resistance, ease of harvest, and shipping quality. Plant breeders have given these characteristics higher priority over flavor and nutritional quality. To receivers and market distributors, quality of appearance is most important; they are also keenly interested in firmness and long storage life. Traditionally, postharvest biology and technology research has concentrated on using appearance and texture as parameters for quality evaluation

Horticultural crops are not widely cultivated in Ethiopia due to small-scale farming systems and poor pre- and post-harvest handling techniques. It can be concluded that the horticulture crop producers in the Northern part of Ethiopia use different cultural practices adopted from innovative technologies and their own tradition cultural practice, and hence they have been increasing the potential for production of fruits and vegetables. However, there are many production constraints during cultivation, harvesting, transportation, marketing and consumption of fruits and vegetables, and hence post-harvest loss was listed as a main challenge to perishable crop producers. Therefore, designing further research on innovative technologies for access supply and consumption of horticultural crops should be required because they are more cash crops than other crops are. In addition, capacity building on post-harvest handling techniques of fruits and vegetables should be promoted.

Isaac Kojo Arah, Gerald K. Box HP , Ho, Ghana. Tomato production has increased in recent years due to the economic and nutritional importance of the crop. This increase is made possible by the numerous research advances made along the entire value chain. However, scientific research has been focussed mainly on production whilst neglecting postharvest issues. Tomato producers have therefore enjoyed good harvests in recent times, though the good harvests of those from developing countries do not translate into profit as most are lost after harvest. From this study, it was revealed that the postharvest quality and shelf life of the fruit in part will depend on some postharvest handling practices and treatments carried out after harvest.

Metrics details. Horticultural crops are sources of vitamins, minerals and dietary fiber, but their cultivation is not widely practiced in developing countries, like Ethiopia due to small-scale farming systems and poor pre- and post-harvest handling techniques. In Ethiopia, particularly in northern region, the production of horticultural crops usually practiced in very few pocket areas, such as at river and lakesides. Thus, the production of fruits and vegetables is just at the beginning stage and getting momentum by governmental and non-governmental organizations. To assess the production potential and post-harvest losses of fruits and vegetables, a survey research was conducted in Tigray Regional State, northern Ethiopia. From the study area, Atsbiwenberta district was selected with its four purposely selected Kebeles Kebelle is the lowest administrative division of Ethiopia next to districts in each administrative region Ruwafeleg , Felegewoni , Golgolnaele and Hayelom in which respondents 30 households from each Kebele were participated. Data were collected from both primary and secondary data and analyzed using simple descriptive statistics like frequency, mean and percentage.

Post-harvest Losses of vegetables and fruit occur at all points in the value chain from production in the field to the food being placed on a plate for consumption. Post-harvest activities include harvesting , handling, storage , processing , packaging , transportation and marketing. Losses of horticultural produce are a major problem in the post-harvest chain.

Фонтейн промолчал. И словно по волшебству в этот момент открылась дверь, и в комнату оперативного управления, запыхавшись, вбежала Мидж. Поднявшись на подиум, она крикнула: - Директор. На коммутатор поступает сообщение. Фонтейн тотчас повернулся к стене-экрану. Пятнадцать секунд спустя экран ожил. Сначала изображение на экране было смутным, точно смазанным сильным снегопадом, но постепенно оно становилось все четче и четче.

Как старшему криптографу ей полагался терминал с самым лучшим обзором. Он был установлен на задней стороне компьютерного кольца и обращен в сторону шифровалки. Со своего места Сьюзан могла видеть всю комнату, а также сквозь стекло одностороннего обзора ТРАНСТЕКСТ, возвышавшийся в самом центре шифровалки. Сьюзан посмотрела на часы. Она ждет уже целый час. Очевидно, Анонимная рассылка Америки не слишком торопится пересылать почту Северной Дакоты. Сьюзан тяжело вздохнула.

Она посмотрела на вентиляционный люк и принюхалась. Но запах шел не оттуда, его источник находился где-то поблизости.
