Developing New Strategies to Support Future Caregivers of the Aged in Canada: Projections of Need and their Policy Implications

Projections of future need for Canadian continuing care services typically uses current utilization patterns and population aging. Accurately assessing this need is much more complex since disability patterns among the elderly are changing and availability of caregivers is affected by changes in family structure. This paper projects annual growth rates between 2001-2031 in the need for informal and formal support among elderly Canadians and discusses the policy implications of the increasing demand for informal caregivers. Using Statistics Canada's LifePaths micro-simulation model, these projections incorporate disability rates and the potential availability of informal caregivers. The authors conclude that continued focus on family to meet the needs of elderly Canadians without increased support is not sustainable in the long term. New strategies to support Canadian caregivers are proposed and their economic feasibility in the public and private markets are evaluated.population aging, caregiving, disability, informal and formal support

Projection of future needs for home care services typically uses current utilisation patterns and population ageing. Accurately assessing this need is much more complex since disability patterns among the elderly are changing and availability of caregivers is affected by changes in family structure. This paper projects annual growth rates between 2001-2031 in the need for informal and formal support among elderly in Quebec and discusses the policy implications of the increasing demand for informal caregivers. Using Statistics Canada Life Paths micro-simulation model, these projections incorporate disability rates and the upcoming availability of informal caregivers. The authors conclude that continued focus on family to meet the needs of elderly without increased formal support is not sustainable in the long term.Population aging, caregiving, disability, informal and formal support, Quebec

Data from: Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

AbstractThe idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are measured. Here, we use a pest-control database encompassing 132 studies and 6,759 sites worldwide to model natural enemy and pest abundances, predation rates, and crop damage as a function of landscape composition. Our results showed that although landscape composition explained significant variation within studies, pest and enemy abundances, predation rates, crop damage, and yields each exhibited different responses across studies, sometimes increasing and sometimes decreasing in landscapes with more noncrop habitat but overall showing no consistent trend. Thus, models that used landscape-composition variables to predict pest-control dynamics demonstrated little potential to explain variation across studies, though prediction did improve when comparing studies with similar crop and landscape features. Overall, our work shows that surrounding noncrop habitat does not consistently improve pest management, meaning habitat conservation may bolster production in some systems and depress yields in others. Future efforts to develop tools that inform farmers when habitat conservation truly represents a win–win would benefit from increased understanding of how landscape effects are modulated by local farm management and the biology of pests and their enemies
