Stakeholders sustainable management in agriculture: lessons from participatory processes
XXIII International Conference Society for Human Ecology, «Navigating complexity: human-environmental solutions for a challenging future», Lisbon 7-10July 2018.Stakeholders are nowadays encouraged to become actively involved in the sustainable management of the territory and, in rural areas such as Castro Verde which is Natura 2000 Special Protection Area and nowadays a UNESCO Biosphere Reserve, as well as in the all country, equilibrium between nature conservation and farm production systems is a key factor for sustainability. This paper focuses on the contribution of local actors to evaluate the agro-environmental commitments applied during the last Portuguese Rural Development Program (PRODER/2007-2013). It aims to propose adjustments and new ideas to improve agricultural sustainable practices by assessing the existing commitments and supporting new public strategies regarding the new 2014-2020 programming cycle of the European Agricultural Fund for Rural Development. This was accomplished through the participation of local stakeholders in a set of five workshops, each one in different agricultural region of Portugal. The three-hour workshops were based on interactive techniques as drivers to generate debate, promote knowledge exchanges and produce new knowledge to be presented to policy makers

LesserKestrel_chick_data
Biometries (mass and wing lenght) and posterior recruitment in the population of Lesser Kestrel (Falco naumanni) chicks ringed as fledglings between 2003 and 2014 in Castro Verde Portugal. Information on brood (clutch size, laying date) of each chick is also provided
Data from: Mechanisms and fitness consequences of laying decisions in a migratory raptor
Seasonal decline in breeding performance is a commonly observed pattern in birds, but disentangling the contributions of environmental conditions (“timing” hypothesis) and individual quality (“quality” hypothesis) to such a pattern is challenging. Moreover, despite the strong selection for early breeding, the individual optimization model predicts that each individual has an optimal breeding window. We investigated the causes and consequences of laying decisions in the lesser kestrel (Falco naumanni) by combining a long-term dataset on reproductive traits with information on food availability. A marked seasonal decline was found in breeding success, mostly mediated by a decline in clutch size. The “timing” hypothesis, supported by the decline in consumption of mole crickets, key prey for prelaying females, seems to explain the seasonal trend in clutch size, as this pattern was recorded in both higher (adults) and lower (yearlings) quality individuals. Contrarily, the higher proportion of yearlings breeding late in the season, rather than a decay in food availability during chick rearing, seems to drive the decline in fledging success, giving support to the “quality” hypothesis. Advanced breeding and increased clutch size, as proxies of reproductive effort, were not offset by lower survival. Low repeatability in both these traits suggests that individual quality is a dynamic attribute and reproduction costs are minimized by individual optimization. Understanding the mechanisms driving individual breeding decisions is critical to anticipate species’ ability to cope with environmental changes. Here, we show that lesser kestrels failing the prelaying food window opportunity compromise reproductive performance, mostly regardless of their individual quality
