For a better production, agriculture areas need to recover at least 20% of natural habitat

International agreements aim to conserve 17% of Earth's land area by 2020 but include no area-based conservation targets within the working landscapes that support human needs through farming, ranching, and forestry. Through a review of country-level legislation, this study found that just 38% of countries have minimum area requirements for conserving native habitats within working landscapes. The study argues for increasing native habitats to at least 20% of working landscape area where it is below this minimum. Such target has benefits for food security, nature's contributions to people, and the connectivity and effectiveness of protected area networks in biomes in which protected areas are underrepresented. Other urgings of the review include maintaining native habitat at higher levels where it currently exceeds the 20% minimum, and a literature review shows that even more than 50% native habitat restoration is needed in particular landscapes. Including a >20% native habitats within working landscapes restoration target offers an unrivaled opportunity to simultaneously enhance biodiversity, food security and quality of life. The post-2020 Global Biodiversity Framework is an opportune moment to include a minimum habitat restoration target for working landscapes that contributes to, but does not compete with, initiatives for expanding protected areas, the UN Decade on Ecosystem Restoration (2021–2030) and the UN Sustainable Development Goals. informacion[at] Garibaldi et al (2020) Working landscapes need at least 20% native habitat.

The Atlantic trade winds regulate the arrival of migratory birds to the Canary Islands and the reproduction of falcons

The Atlantic trade winds regulate the arrival of migratory birds to the Canary Islands and the reproduction of falcons

Large-scale environmental forces can influence biodiversity at different levels of biological organization. Climate, in particular, is often associated with species distributions and diversity gradients. However, its mechanistic link to population dynamics is still poorly understood. Here, the full mechanistic path by which a climatic driver, the Atlantic trade winds, determines the viability of a bird population is unravelled. The breeding population of Eleonora's falcons in the Canary Islands was monitored for over a decade (2007–2017), and different methods and data to reconstruct how the availability of their prey (migratory birds) is regulated by trade winds were integrated. GPS allowed tracking foraging movements of breeding adults, weather radar was used to monitor departure of migratory birds, and an individual-based, spatially explicit model simulated their migration trajectories. Results demonstrate that regional easterly winds regulate the flux of migratory birds that is available to hunting falcons, determining food availability for their chicks and consequent breeding success. By reconstructing how migratory birds are pushed towards the Canary Islands by trade winds, most of the variation (up to 86%) in annual productivity for over a decade is explained. This study unequivocally illustrates how a climatic driver can influence local-scale demographic processes while providing novel evidence of wind as a major determinant of population fitness in a top predator. informacion[at] Gangoso et al (2020) Cascading effects of climate variability on the breeding success of an edge population of an apex predator.
