Esta metodología para la evaluación participativa de pastizales y tierras de pastoreo (denominada PRAGA) se desarrolló a través del proyecto "Evaluación participativa de la degradación de la tierra y la gestión sostenible de la tierra en sistemas de pastizales y pastos", financiado por el Fondo para el Medio Ambiente Mundial y ejecutado por FAO y la UICN. La metodología se probó en cinco países (Burkina Faso, Kenia, Kirguistán, Níger y Uruguay) para comprobar su eficacia y valor.

In rangelands and grasslands, land degradation has an immediate and local impact by disrupting ecosystems from functioning, threatening livelihoods and negatively affecting social cohesion. It also threatens productivity while dovetailing with the threats of climate change in these ecologically fragile areas. The understanding of land degradation in rangelands and grasslands is weak, which is attributed to a lack of robust data and a misunderstanding of management objectives.

In this publication, we take stock of the knowledge and know-how induced by the BIODEV2030 project’s first step, which is to assess the main threats to biodiversity and provide elements to address the following specific questions: how were main threats to biodiversity identified and ranked and associated sectors selected in each country? Were the different methods converging in identifying top threats?

Nature-based Solutions (NbS) are seen as a response to many societal challenge. It is becoming increasingly obvious that protected and conserved areas (PCAs) are a major vehicle for NbS and essential to their success in many situations.

This report presents the results of a broad assessment of freshwater diversity in the Douro river basin in Spain and Portugal. The Douro river basin is the largest of the Iberian Peninsula, and an ecological region of great value due to the high diversity of ecosystems and the number of species. A total of 14 sites, either identified as Key Biodiversity Areas (KBAs) or potential KBA sites, were surveyed for fish and macroinvertebrate species.

Com base no volume de rejeitos lançados e na extensão das áreas atingidas, o rompimento da Barragem de Fundão, em Mariana, Minas Gerais, foi o maior desastre ambiental de todos os tempos na mineração brasileira, e um dos mais graves do mundo. Ao serem transportados a jusante da barragem rompida, os rejeitos foram se acumulando ao longo dos rios e alcançaram o estuário do Rio Doce, na ecorregião marinha do Leste brasileiro, afetando importantes ecossistemas.

Based on the volume of tailings releases and the distance they travelled, the Fundão Dam failure in southeast Brazil (Mariana, Minas Gerais state) was the largest ever environmental disaster in Brazil’s mining industry, and one of the world’s most serious. As they dispersed downriver, the tailings accumulated along the riverbanks and reached the Rio Doce estuary in the Eastern Brazilian Marine Ecoregion.
