Globally, postharvest losses contribute to food shortages and ongoing food insecurity. Food production is continued to be lost and wasted. Agricultural practices in most Middle Eastern countries including Oman are not progressive in achieving food security and sustainability due to the arid and semi-arid climatic conditions, poor productivity and postharvest losses. Food loss and waste reduction efforts have received a lot of attention because of the importance of enhancing productivity, food security and overall sustainability. Value addition of agricultural products has a higher impact on productivity by lowering waste and improving profit. Therefore, this study aimed to evaluate the current status of agricultural production and productivities, value addition needs, and quantify the technology transfer and capacity building needs for value addition leading to productivity improvement in agriculture, and to investigate the value addition based agritourism potentials for adoption in Oman. Four agricultural products with potential for value addition were selected for the study; date, banana, tomato, cucumber, and six governorates growing those crops were selected for the study. Questionnaire surveys as primary data collection were distributed among the stakeholders such as farms, value addition industries, relevant ministries and other institutions to collect the required data about the current status and potentials for value addition, technology transfer, capacity building, productivity improvement and on agritourism. The crops selected in this study are all seasonal in which farmers and growers face challenges such as postharvest handling losses, marketing, price variations, as well as competition with imported products. Value addition of agricultural products can improve the shelf life of the products for longer periods and sell during off seasons. Six prominent date value-addition factories and a few tomato factories were visited for data collection, while secondary data were collected on banana and cucumber as there were no value addition factories available in the sultanate. The most value-added considered for the study were; date with nuts, syrup, and paste of Khalas and Fardh date varieties under date value-added products, banana chips, paste and juice under banana value-added products, tomato ketchup, paste and juice under tomato value-added products and cucumber pickle, paste and juice under cucumber value-added products. According to the number of methods used in value-addition, four mechanization levels were categorized on each value addition process. The productivity ratios were computed to determine the productivity improvement by each value-added product from the raw product base values. Protocols on value addition were developed as value addition guidelines and procedures sheets, each sheet comprised 13 important features. These protocols are for the use of farmers, growers, extension officers, planners, institutions and all stakeholders. The potential agricultural sites, necessary activities and value-added products for promoting agritourism were identified. The SWOT analysis on five categories was conducted in this study on productivity improvement, value addition, technology transfer, capacity building and agritourism. The results showed several hindrances promoting value addition in Oman; only very few Small and Medium Enterprise category farm landholdings could be found with large sizes of 2-10 ha or more, only 4% each of date and tomato farms out of 72 and 25 farms, 2% of banana farms out of 45 farms had some technology transfer and capacity building activities conducted, while no such activities used for value addition by cucumber farms. The technology transfer and capacity building are in the initial stage and need more efforts and investments in order to promote value addition. In the case of productivity improvement through value addition, date value-added products achieved the highest productivity ratios (dates with nuts 540% in Khalas and 360% in Fardh). The potential productivity improvement in other crops also showed highly positive results in productivity ratios (value-added products with the highest ratios; banana chips 854%, tomato ketchup 600% and cucumber paste 650%). Under protocol development for value addition, 36 value addition guideline sheets were developed, 9 for each crop, and each comprised 13 guideline features such as mechanization level, investment, technology transfer and capacity building needs, possible productivity improvement and net profit. According to agritourism, only 3%, 7%, 8% and 0% of 72 date farms, 45 banana farms, 25 tomato farms and 16 cucumber farms, respectively, were applying some form of agritourism. Potential agritourism destinations and farm activities were identified and potential income generation was computed. Five different SWOT matrices were developed on value addition, technology transfer, capacity building, productivity improvement, and agritourism. The SWOT analyses recognized the strengths, weaknesses, opportunities and threats and hence strategies and steps required for improvements under each category could be recommended. The lack of SME-type farms with larger farm landholdings is one of the major weaknesses hindering value addition industry. This required to be rectified and promoted among all governorates to improve the value addition industry. The technology transfer and capacity building required for value addition are also in their infancy state due to lack of supporting program, financial support, institutional, public and private sector collaborations that need more attention and support to improve. Value addition has the potential to improve land, water and labor productivities significantly under arid conditions. The value addition industry aligns with agritourism which can generate more farm income and benefit both sectors; it need initiatives to make awareness programs for farmers and tourists and develop farm visiting activities. The developed guidelines-procedure sheets will provide decision-making support for farmers, producers, and extension officers and will improve product quality, farm income, productivity, new jobs, and agricultural sustainability. Most of the above recommendations align well with Oman's 20-year holistic development plan of Oman Vision 2040.
