Ageism: A Factor in the Nutritional Vulnerability of Older People?

Unlike other population groups, the rights, needs and contributions of older people in developing countries are not well understood. With the absence of information about how to assess the nutritional status and vulnerability of older people, HelpAge International joined forces with the London School of Hygiene and Tropical Medicine in the early 1990s to launch a research programme. Seven years later some of the basic questions can now be answered but there remains much more to do.
Although older people are increasingly acknowledged as a vulnerable group in emergencies, NGO responses often fail to meet their needs. The question is whether there are real difficulties in service adaptation or whether ageism is one of the greatest barriers to the provision of appropriate services for older people.     

Socioeconomic determinants of long-term cropland fallowing: smallholders in north-western Uganda

SUMMARY

Long-term cropland fallowing decisions of farmers in the West Nile Province of Uganda were studied. Tabular and regression methods are used to examine the relationship between farm and household factors and seasons of net fallowing. The results show that farmers plan to decrease the rate of fallowing in the immediate future. Serious (but undocumented) problems in maintaining cropland productivity could result. Population density had a large and negative effect on net fallowing (seasons of fallowing less seasons of crops), decreasing from the current average of ?0.6 seasons to ?2.21 seasons for a doubling of population. This 268% decrease in the use of fallowing could occur in as few as 13.5 years, assuming a 3% annual population growth rate. Farms larger in size, but with no increase in per capita cropland availability, had a higher rate of net fallowing. Cashcrop production was negatively associated with net fallowing, whilst farmer age had a positive association.

The results have implications for both agricultural policy and guidance for further research on cropland fallowing. Increased cash-cropping should not be recommended unless the full economic costs of using land resources are evaluated. Much of the increased area for cash-crop production would come from fallowed land, decreasing the rate of fallowing and thus increasing the potential for soil degradation. Fallowing has long been used in the area to maintain cropland productivity. Building upon farmers current practices and improving fallowing through the use of green manures and agroforestry could prove to be more economical than the use of mineral fertilizers. Investigating why farms larger in size and those with older head-of-households were able to use fallowing more effectively may provide key information for the development of more productive fallowing technologies.     

Investigation of stakeholders' awareness and adoption of Inherently Safer Design (ISD) principles in South African utility industry projects

The paper examines the level of awareness of stakeholders in adopting Inherently Safer Design (ISD) principles in the Project Life Cycle Management (PLCM) of South African Energy utility projects. It seeks to understand whether stakeholders in the latter stages of the Project Life Cycle are competent to make design change decisions on these projects. ISD principles are essentially useful for reducing risks and as such, safety experts have acknowledged it as an excellent approach in the design process. However, there are no known efforts to date that attempt to integrate ISD concepts into PLCM. This paper seeks to fill this gap. This study, through the review of extant literature establishes that ISD principles can be used in project procurement, and adopts a quantitative survey approach in obtaining information from stakeholders in the South African utility industry. Findings reveal that the principles of inherent safety are permeating into the management of South African utility projects but the level of awareness and its adoption are below optimal levels. It also emerged that there is a divergent awareness of ISD strategies amongst PLCM stakeholders and that the design engineers are better informed about the ISD approach of eliminating risks and hazards in the industrial systems studied than other stakeholders. The findings also indicate that the level of awareness of stakeholders of ISD principles is greater within earlier project phases. Based on these findings, the paper concludes that the hazards witnessed within the project execution and finalization phases could be as a result of the low levels of awareness, divergent views and lower use of ISD strategies by PLCM stakeholders. It is suggested that the level of awareness of the principles, concepts, basics and benefits of integrating ISD into PLCM be raised amongst stakeholders functioning within utility industry project procurement in South Africa and that design changes be limited to the earlier phases of utility project procurement.
