This study reviewed research published after 1990 on the economics of agricultural mechatronic automation and robotics, and identified research gaps. A systematic search was conducted from the following databases: ScienceDirect, Business Source Complete, Wiley, Emerald, CAB Abstract, Greenfile, Food Science Source and AgEcon Search. This identified 4817 documents. The screening of abstracts narrowed the range to a dataset of 119 full text documents. After eligibility assessment, 18 studies were subjected to a qualitative analysis, with ten focused on automation of specific horticultural operations and eight related to autonomous agricultural equipment. All of the studies found some scenarios in which automation and robotic technologies were profitable. Most studies employed partial budgeting considering only costs and revenues directly changed by the introduction of automation or robotics and assuming everything else constant. None examined cropping system changes, or regional and national impacts on markets, trade and labour demand. The review identified a need for in-depth research on the economic implications of the technology. Most of the studies reviewed estimated economic implications assuming that technology design parameters were achieved and/or based on data from prototypes. Data are needed on the benefits and problems with using automation and robotics on farm. All of the studies reviewed were in the context of agriculture in developed countries, but many of the world’s most pressing agricultural problems are in the developing world. Economic and social research is needed to understand those developing country problems, and guide the engineers and scientists creating automation and robotic solutions.

A systematic review was conducted to examine expected economic outcomes of rubber-based agroforestry systems during mature rubber stage in comparison with monoculture rubber farming. Twelve studies were identified for a narrative synthesis of economic outcomes of the mature rubber production systems. The review found that whilst monoculture rubber production may produce higher income in some cases, particularly when rubber prices are high, profitable diversified rubber agroforestry systems were reported in all but one study. Rubber agroforestry has the potential to reduce the vulnerability of smallholders to volatile markets for rubber, particularly if the share of income from secondary species is substantial. Shade-tolerant crops with small canopies (e.g. coffee, bamboo and tea) are reported as ideal intercrops for rubber. Economically advantageous systems reported appeared to be rubber combined with species which provide additional income in the medium to long term (e.g. sheep and high value timber) and/or enhance ongoing cash flow with a lengthy productive lifespan and regular harvests (e.g. durian and gnetum). However, these systems are subject to many constraints such as labour availability, investment and management capacity and market conditions for secondary products. The review showed an absence of farm portfolio studies aimed at finding risk reducing enterprise combinations. Future research on economic outcomes of rubber agroforestry systems should firstly distinguish traditional jungle rubber from rubber agroforestry systems which use clonal rubber similar to those used in monoculture rubber, and secondly consider the full value of secondary products even if they are grown for own consumption.

This multiple case-based study investigates the relationship between recruiting agents and the UK universities who act as their principals. The current extensive use of agents in UK higher education may be seen as an indicator of the financial impact made by international students. The study analyses the practice of agent management and explores the manner in which power and control interact. The study employed semi-structured interviews and group discussions involving up to 6 respondents from each of the 20 UK case institutions. The qualitative data reveal a considerable variation in the manner in which the universities manage their agency relationships. Through the joint consideration of control measures and use of power, five distinctive approaches have been identified. The study also reveals that over-dependence on agents reduces the power of the principal, and consequently, the principal's ability to exercise control, particularly in highly competitive global and national markets.

Urban agriculture refers to any type of activity located within or around a city designed to provide ecosystem services. Given the rapid population growth and urbanization, urban agriculture is seen as a potential alternative route to a more sustainable urban food system. This review answers the main question: What are the benefits of non-commercial of Urban Agriculture (NCUA) forms and its contribution towards food production? using a systematic literature review approach. The methodology involved capturing 1355 recent articles from qualified search engines, using key terms according to the defined question, then screened for relevance and the defined scope of this review, resulting in a final selection of 40 articles for analysis. The results show that implementing NCUA practices has multifaced social, economic, and environmental benefits, such as improving people’s health, reducing expenditure on food and creating sustainable cities, highlighting the need to recognize the multifaceted role of NCUA in promoting a more sustainable lifestyle and strengthening local communities and engagement. Moreover, awareness of urban agriculture differs between developed and developing countries, as does the recognition and valorization of its benefits. Further research is needed to examine the enabling factors and barriers to NCUA adoption in different urban context, the resource implications, and the long-term sustainability of these practices.
