“…So far, different attempts have been made to come up with an appropriate agronomic and pre-harvest management to increase potato tuber productivity in Ethiopia (Worku et al., 2013; Gebru et al., 2017; Kolech et al., 2015; Diro, 2016). However, Very few studies have been attempted to assess the extent of losses at different stages and all of them are survey based works and they are subjective (Tadesse et al., 2018; Emana and Nigussie, 2011; Urge et al., 2015). It is therefore, important that objectively evaluating the post-harvest quantitative and qualitative loss be given as much attention as production practices.…”

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. Load tracking approach was used by simulating existing postharvest handling and storage practice of potato tuber in the study area. Quantitative post-harvest loss assessment along the supply chains, qualitative loss and shelf life estimation at retail market were investigated using standard methods. Results showed that more mechanical damages and seepage loss were observed in case of poor road quality and transportation. During extended storage time (30 days) at ambient environment, potato tubers transported from Dedo to Jimma resulted in high average weight loss (17.9 ± 0.9%), significant loss in firmness (7.0 ± 0.6N in average) and average vitamin C content of 9.20 ± 0.05mg/100g as compared to tubers transported from Seka to Jimma market. This implies that, lack of good road access and transportation facility contributed for more external mechanical damages and internal injuries which will critically enhance rate of degradation of tubers in later stages of storage.

“…Postharvest management determines food quality and safety, competitiveness in the market, and the profits earned by producers. In most developing countries, postharvest management of produce is far from satisfactory (Tadesse et al, 2018). The major constraints include inefficient handling and transportation; poor technologies for storage, processing, and packaging; involvement of too many diverse actors; and poor infrastructure.…”

“…Kiaya (2014) states that food losses are mainly due to poor infrastructure and logistics, lack of technology, insufficient skills, knowledge and management capacity of supply chain actors and lack of markets (these factors are largely common amongst poor small-scale farmers). Hence, most food losses are experienced by poor farmers who become greatly disadvantaged due to the losses as this has financial implications (Tadesse et al, 2018). Therefore, it is of paramount importance to interrogate the extent to which national policies in Lesotho integrate post-harvest management practices.…”

“…Food availability can be increased without further exploitation of natural resources if food losses are curbed. Tadesse et al (2018) assert that increasing the food availability is therefore not only increasing the productivity in agriculture, but also lowering losses. Minimizing this loss has a great significance for food security, economic growth and welfare of the society (Kasso and Bekele, 2018).…”

Despite global efforts to increase food availability and curb high incidence of malnutrition in Africa, there are concerns with regard to high post-harvest losses in Africa. Lesotho like most countries in sub-Saharan Africa faces documented challenges with food insecurity and nutrition. Food availability could be increased by reduction of post-harvest losses without further exploitation of resources. Mitigation of post-harvest losses is seen as a possible antidote for increasing food availability and nutritional status in countries experiencing high food losses. This study investigated the extent of integration of post-harvest management in agricultural policy in Lesotho and strategies to minimise post-harvest losses. Purposive sampling was utilised in order to select a sample of twenty-five respondents on which interviews were conducted. Thematic analysis was used to identify a set of overarching themes that can be used to describe the policy environment and strategies to reduce postharvest losses. The analysis suggests that there is absence of a direct policy to guide post-harvest management activities in Lesotho, it is only referred to indirectly in other policies with the exception of dairy products sector which has a direct post harvest management policy. Strategies to curb postharvest losses were also identified. The study concludes that there is need for a direct policy to address post-harvest management in Lesotho.

“…Domestic consumption of both fresh and processed Irish potato stands at 4.63 kg/capita (FAOSTAT, 2015). Irish potato was introduced to Nigeria in the early 19th Century when it was first planted in the Jos Plateau (Taiy et al, 2017;Tadesse et al, 2018). Plateau State has an average maximum temperature of 31.7oC and a minimum temperature of 15oC.…”

Notable efforts are ongoing to improve Irish potato production in Plateau State, the major producer of the crop in Nigeria. However, little attention has been given to the profitability of the enterprise while the determinants of profitability level are scanty in the literature. Thus, paper analyses the profitability of Irish-potato farming using primary data from 252 Irish potato farmers in Plateau State, Nigeria. Cost structure and profitability level of Irish potato farming were investigated using farm budgeting technique while probit regression model was used to examine the determinants of profitability level of Irish potato farms. Irish potato farming was found to be profitable with most (53.97%) farmers at high profitability level. The net farm income was ₦604, 245.81 per hectare with returns per naira spent of ₦1.70. The cost structure showed that costs of seeds, labour and fertilizer made up the largest share of the total cost of production per hectare. The probability that a farm will be at high profitability level was determined by agrochemicals, sex, farm size and labour at 1% level, respectively. It was concluded that increasing agrochemicals, reducing farm size and labour and being a male farmer will improve profitability level of Irish potato farms. This study recommended that increased use of agrochemicals and more efficient use of labour and farm land be encouraged among potato farmers increase their profitability level.
