This paper examines the spatial pattern of food discount stores in Switzerland, where private actors made location decisions without interference from planning regulations until 2016.
Intensive agriculture is among the main drivers of diversity decline worldwide. In Central Europe, pressures related with agriculture include habitat loss due to the consolidation of farming units, pesticide and fertilizer use, and shortened crop rotations. In recent decades, this development has resulted in a severe decline of agrestal plant communities.
The near elimination of inland salt marshes in Central Europe occurred throughout the 19th and 20th centuries, and the currently remaining marshes exist in a degraded condition. This work examines the impact of groundwater level on the growth of plants from a seed bank obtained from a degraded salt marsh in proximity to still existing one through an ex-situ experiment.
Forests cover about 40 % of the European Union (EU), providing a wide spectrum of invaluable ecosystem services to more than half a billion people. In order to protect and harness this crucial asset, EU policies are advancing multifunctional management.
Tree root systems stabilize hillslopes and riverbanks, reducing landslide risk, but related data for the humid tropics are scarce. We tested fractal allometry hypotheses on differences in the vertical and horizontal distribution of roots of trees commonly found in agroforestry systems and on shear strength of soil in relation to root length density in the topsoil.
Spatial planning plays an important role in cropland protection, but its effectiveness is often questioned in the face of ongoing urban and infrastructure growth. Moreover, methods to assess the effectiveness of spatial planning are lacking. In Switzerland, the revision of the national spatial planning act in 2014 was a new starting point for stricter prescriptions on urban development.
L’objectif du présent rapport est d’offrir un cadre conceptuel permettant de faire face aux problèmes de sécurité alimentaire dans une situation de pénurie d’eau pour l’agriculture.
This edition of Unasylva comes in the wake of the United Nations Conference on Sustainable Development, Rio+20,which, among other things, produced a document called The Future We Want.
This document details the activities that were undertaken by the Food and Agriculture Organization of the United Nations (FAO) and cooperating agencies (the Department of Agriculture, Forestry and Fisheries of South Africa (DAFF), the Africa Union Inter-African Bureau for Animal Resources (AU-IBAR) and the Southern Africa Development Community (SADC)) leading to the production of a Regional Aqu
Aquatic genetic resources (AqGR) play a crucial role in contributing to global food security and nutrition, as well as sustainable livelihoods.
