Does participatory water management contribute to smallholder incomes? Evidence from Minle County, Gansu Province, P.R. China

Since the early 1990s, the Chinese water sector has undergone an important institutional reform that has shifted major responsibilities in irrigation management from the government toward water users, organized in so-called Water User Associations (WUAs). Such participatory water management is not only assumed to increase water use efficiency, but also to stimulate the incomes of member households. This study aims to provide empirical evidence of the impact of participatory water management on WUA performance and farmer incomes, using data collected for the year 2007 among 317 households and 35 WUAs in Minle County, Gansu Province. We find that having democratically elected leaders has a positive effect on WUA performance, by increasing investment levels and improving canal quality. Participation in decision making, however, has a significant negative impact on canal quality and does not affect other WUA performance indicators. Two aspects of WUA performance, investment levels and financial health, are found to have a positive impact on the farm income of member households, while water use per mu has a significant negative impact on farm incomes. We find evidence that households belonging to better performing WUAs increase their farm incomes at the expense of non-farm income. The resulting net impact of participatory water management on total household income is not significant for the households in our sample

Are farm households’ land renting and migration decisions inter-related in rural China?

Economic reforms in rural China have stimulated the development of land and labour markets. The increasing importance of these two markets suggests that they might be closely inter-related, but proper statistical tests are lacking. This paper examines the factors that determine the participation of farm households in land renting and migration, and investigates whether participation in land renting and migration influence each other, using a seemingly unrelated bivariate probit regression. Data from a household survey held in 2000 in three villages in the north-east of the Jiangxi Province were used to estimate the land renting and migration equations. Household characteristics, fixed factors, household land and labour endowments, institutional factors, and land and labour prices were used as explanatory variables in both equations. We found that the error terms of the land renting equation and the migration equation were strongly correlated, confirming that there is a negative relationship between land renting and migration

Beyond Speculative Robot Ethics

In this article we develop a dialogue model for robot technology experts and designated users to discuss visions on the future of robotics in long-term care. Our vision assessment study aims for more distinguished and more informed visions on future robots. Surprisingly, our experiment also lead to some promising co-designed robot concepts in which jointly articulated moral guidelines are embedded. With our model we think to have designed an interesting response on a recent call for a less speculative ethics of technology by encouraging discussions about the quality of positive and negative visions on the future of robotics.

Land tenure reforms and land conservation investments in China – what does real option value theory tell us?

Land conservation investments can make an important contribution to avoidance and mitigation of land degradation. Lack of tenure security and land transferability may, however, limit the extent to which farmers undertake such investments. Using real option value theory, this paper investigates the expected impact of the market-oriented tenure reforms in China since 1998 on land conservation investment incentives. It postulates that the reforms are more likely to elicit land conservation investments in areas where land markets are developing. This paper further argues benefits of the land tenure reforms will be underestimated if only the intrinsic but not the time value of changes in the investment incentives will be considered. The findings obtained from this research provide a better understanding of the relationship between the land tenure reforms and land conservation investments, and are likely to serve sustainable land management in China and elsewhere

A systematic review of attitudes, anxiety, acceptance, and trust towards social robots

As social robots become more common, there is a need to understand how people perceive and interact with such technology. This systematic review seeks to estimate people’s attitudes toward, trust in, anxiety associated with, and acceptance of social robots; as well as factors that are associated with these beliefs. Ninety-seven studies were identified with a combined sample of over 13,000 participants and a standardized score was computed for each in order to represent the valence (positive, negative, or neutral) and magnitude (on a scale from 1 to − 1) of people’s beliefs about robots. Potential moderating factors such as the robots’ domain of application and design, the type of exposure to the robot, and the characteristics of potential users were also investigated. The findings suggest that people generally have positive attitudes towards social robots and are willing to interact with them. This finding may challenge some of the existing doubt surrounding the adoption of robotics in social domains of application but more research is needed to fully understand the factors that influence attitudes

Assessment of personal care and medical robots from older adults' perspective

Demographic reports indicate that population of older adults is growing significantly over the world and in particular in developed nations. Consequently, there are a noticeable number of demands for certain services such as health-care systems and assistive medical robots and devices. In today's world, different types of robots play substantial roles specifically in medical sector to facilitate human life, especially older adults. Assistive medical robots and devices are created in various designs to fulfill specific needs of older adults. Though medical robots are utilized widely by senior citizens, it is dramatic to find out into what extent assistive robots satisfy their needs and expectations. This paper reviews various assessments of assistive medical robots from older adults' perspectives with the purpose of identifying senior citizen's needs, expectations, and preferences. On the other hand, these kinds of assessments inform robot designers, developers, and programmers to come up with robots fulfilling elderly's needs while improving their life quality

A brief review of robotics technologies to support social interventions for older users

In the last few decades, various studies demonstrated numerous robotics applications that can tackle the problem of the ageing population by supporting older people to live longer and independently at home. This article reviews the scientific literature and highlights how social robots can help the daily life of older people and be useful also as assessment tools for mild physical and mental conditions. It will underline the aspects of usability and acceptability of robotic solutions for older persons. Indeed, the design should maximise these to improve the users' attitude towards the actual use of the robots. The article discusses the advantages and concerns about the use of robotics technology in the social context with a vulnerable population. In this field, success is to assist social workers, not to replace them. We conclude recommending that care benefits should be balanced against ethical costs
