Management of the land-sea interface is essential for global conservation and sustainability objectives because coastal regions maintain natural processes that support biodiversity livelihood billions people. However, assessments have focused strictly on either terrestrial or marine realm. Consequently, understanding overall state Earth's poor. We integrated human footprint cumulative impact maps in a assessment anthropogenic pressures affecting regions. Of globally, 15.5% had low pressure, mostly Canada, Russia, Greenland. Conversely, 47.9% were heavily affected by humanity, most countries (84.1%) >50% their degraded. Nearly half (43.3%) protected areas across exposed to high pressures. To meet objectives, all nations must undertake greater actions preserve restore within borders.costa, huella humana, impacto humano cumulativo, litoral, presión restauración, tierras vírgenes Resumen El manejo de la interfaz entre tierra y el mar es esencial para los objetivos mundiales conservación sustentabilidad ya que las regiones costeras mantienen procesos naturales sostienen biodiversidad al sustento miles millones personas. Sin embargo, análisis se han enfocado estrictamente en ámbito marino o terrestre, pero no ambos. Por consiguiente, conocimiento del estado general planeta muy pobre.

Evaluation of landscape ecological risk in key ecological functional zone of South–to–North Water Diversion Project, China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 147, P. 109934 - 109934

Published: Jan. 25, 2023

The key ecological functional zone plays a significant role in maintaining ecosystem security, water conservation function and environmental protection. However, owing to rapid industrialization urbanization, some zones have undergone great changes land use, which has changed the landscape pattern characteristics resulted risks, affecting regional environment security. In this study, core source area of Middle Route China's South–to–North Water Diversion Project is selected as case study. A risk index (ERI) was constructed evaluate driven by use transformation. Moreover, ERI's spatiotemporal were investigated using combination geographic information systems geostatistical techniques, reveal dominant types associated with risks their causes. We found that (1) there not notable shift level increased slightly from 2010 2015. conversion previously unproductive into places for industrial production agricultural productive played phenomenon. From 2015 2020, Danjiangkou Reservoir officially started operation. Furthermore, improvement residents' awareness protection natural forest significantly reduced risk. (2) strong positive autocorrelation, exhibiting high east center, low west periphery. (3) An obvious corresponding relation exists between impacts topography, soil, climate on patterns Additionally, strict policies implemented Chinese government realized remarkable achievements promoting risks. Our study can provide decision–making basis local authorities conduct prevention activities ensure sustainable northward flow clean water.

Assessing Changes in Land Use/Land Cover and Ecological Risk to Conserve Protected Areas in Urban–Rural Contexts

Land use/land cover (LULC) changes in response to natural factors and human activities constitute a pressing issue for the conservation of Protected Areas urban–rural landscapes. The present study investigated LULC Jajrud Area (JPA) Kavdeh Wildlife Refuge (KWR) Tehran province, Iran, between 1989 2019. To inform ecological measures JPA KWR, were identified monitored using Landsat imagery from In addition, landscape risk (ER) was evaluated by conducting pattern index analysis. Then, importance different indicators affected ER these two PAs assessed Delphi method, expert opinions solicited through questionnaire. As JPA, high-density pasture declined most over 1989–2019, 38.6% (29,241 ha) 37.7% (28,540 ha). contrast, built-up areas increased most, 10.4% (7895 11.9% (9048 Water bodies also increased, 0.88% (676 0.94% (715 cropland gardens 2.14% (1647 3.4% (2606 Built-up 0.05% (45 0.09% (75 0.69% (538 0.71% (552 Finally, decreased 29.4% (22,603 28.5% (21,955 At same time, high very classes more so compared KWR. considering both changes, method demonstrated that greatest impacts occurred JPA.
