Historical landmarks of decent work

Structured Abstract Purpose: this article systemizes the main historical milestones which led to the current concept of decent work and presents some implications for business. Approach: after presenting the scenario which gives a special meaning and importance to decent work, the historical landmarks are systematized until the definition of the Decent Work Agenda. Findings: Decent work is a concept that has evolved since the ILO Foundation in 1919 and had several important steps throughout its development: Philadelphia Declaration in 1944, ILO constitution update in 1946, Universal Declaration of Human Rights in 1948, Human Development Report, first edition in 1990, World Summit for Social Development in 1995, ILO Declaration on Fundamental Principles and Rights at Work in 1998, World Economic Forum in 1999, Global Compact in 2000, United Nations Millennium Declaration in 2000, ILO Declaration on Social Justice for a Fair Globalization in 2008, Global Jobs Compact in 2009, and inclusion in the 2030 Agenda for Sustainable Development. Throughout this development we can witness the refinement and operationalization of the concept, its institutionalization and its spread at political level, at least as an intention. Practical implications: the business area is a privileged forum to turn policies into practices and some examples are provided. Value: although decent work emerged in a very different social and economic scenario from the present time, it is claimed to be even more topical and relevant for the development of business and society today.

Cork oak transplant: A new reality? A Physiological Approach to maximize sucess rate.

Cork oak tree (Quercus suber L.), in Portugal, is considered the national tree and have special demands and legal protection when dealing with silviculture management (pruning, debarking, thinning). Being a species of slow growth, cork oak transplanting procedures can be a valuable asset either from the economic or ecological rationales to relocate trees, re-populate areas affected by high tree mortality, increase tree density to control erosion on montado ecosystems or landscape design. This study focuses the impacts and physiological responses of ten juvenile rain fed cork oak trees (with diameter at breast height between 6 and 16cm), when subjected to transplant operations. The work was conducted in a cork oak woodland experimental plot at the campus of the University of Évora (SW Portugal), during the year of 2015. Tree’s transplants were performed with a truck-mounted hydraulic spade transplanter coupled with a proposed methodology to maximize tree survival rates, addressing techniques to limit canopy transpiration and to improve root systems prior to transplant. Tree ecophysiological indicators (sap flow, leaf water potentials and stomatal conductance) were monitored comprising the periods before and after transplant operations, and water stress avoidance practices were established to promote post-transplant tree status recovery, including irrigation to match average daily accumulated sap flow. Transplant operations were considered successful when the tree's water uptake inferred from sap flow exhibited a high correlation with solar radiation and returned to its undisturbed or pre-transplant water potential gradients in the following 2 to 3 weeks. The post-transplant tree nourishment follow up included permanent sap flow measurements and identified the time elapsed after transplantation from which the tree recovers its normal transpiration thresholds and response. Our results suggest that by following the proposed methodology the sampled cork oak trees exhibited a transplant success rate of 90%.
