ECOSYSTEM SERVICES AND RIVER RESTORATION

Understanding the economic and social value of ecosystem services in a river system can help prioritise river restoration projects. Currently, public administrations rarely consider river restoration projects as investments. Funding for restoring natural capital is substantially lower than the funding available to build and maintain built infrastructure. By reframing river restoration projects as restoration of natural capital it is possible to attract the financial resources needed to restore river systems and better integrate environmental and social values.

HOW CAN A RIVER BE HYDROLOGICALLY RESTORED?

This technical note on river restoration discusses how hydrological restoration should be incorporated in river restoration, and which are the most adequate strategies to design and implement the restored (functional) flows in rivers. Restoration of a river's flow regime should be the first step in any attempt to recover its ecological integrity, as the flow pattern determines, more than any other physical or environmental feature, the structure and spatial-temporal functioning of the river system.

WHAT IS RIVER RESTORATION?

This technical note explores the concept of river restoration, addressing it as a process to re-establish or recover a natural system through the elimination of the impacts that degrade it throughout a prolonged period of time, until a natural and self-sustaining functioning is achieved. The process of restoration must attain naturalness, functionality, dynamism, complexity, diversity and resilience of the natural system. Real restoration is, therefore, self-restoration.

CHANNEL GRADIENT: Calculation process using GIS

This technical note on river restoration adresses the calculation of river channel gradients using Geographic Information Systems (GIS). The channel gradient is a fundamental parameter in the geomorphologic characterisation of river systems; it is a reflection of the changes in the longitudinal sequence of a river through the presence of waterfalls, step pools (fasts and pools), riffle pools (rapids and pools), etc., which makes it a discriminating factor of environmental dynamics of differentiated processes.

RIVER SINUOSITY INDEX: Geomorphological characterisation

This technoical notes on river restoration explores the concept of sinuosity. Sinuosity is used to define the degree of meandering of a riverbed, which is then used to establish geomorphological river types.

FLUVIAL TERRITORY: Restoration space

This technical note on river restoration explores the concept of Fluvial Territory as a space of sufficient width and continuity to retain or regain the hydro-­‐geomorphologic dynamic, obtain a continuous riverside passageway that would ensure ecological diversity (Habitats Directive 1992/43/CE) and the bioclimatic function of the river system, comply with a good ecological state (Water Directive 2000/60/CE), laminate the avenues naturally (Flood Directive 2007/60/CE), solve management problems of floodable areas, as well as improving and consolidating the landscape around the river.

Lineamientos para una ganadería ambientalmente sustentable en el Delta del Paraná

Los humedales brindan una amplia variedad de bienes y servicios ecosistémicos fundamentales para la sociedad. Por esta razón, a lo largo de la historia de la humanidad han constituido sitios de gran atracción, donde florecieron culturas importantes debido a la oferta de agua y de numerosos recursos naturales básicos. Las funciones ecosistémicas de los humedales y, en última instancia, los bienes y servicios que estos proveen a la sociedad,dependen de las características de los componentes, la estructura y los procesos que tienen lugar en estos ecosistemas. Sin embargo, para que la provisión de bienes y servicios se mantenga a largo plazo, es necesario que se preserve la integridad ecológica de los humedales.

Keep it fresh or salty

This report provides guidance for program and project developers from, or working in, developing
countries on the numerous funds and finance mechanisms that can provide carbon finance for wetland carbon conservation and restoration. It also highlights ways to access and link carbon activities with non-carbon based sources of financing.

The Role of Mangroves in Fisheries Enhancement

Some 210 million people live in low elevation areas within 10 km of mangroves and many of these directly benefit from mangrove-associated fisheries. Yet, these people are often unaware of the key role mangroves may play, especially if the associated fisheries are offshore.

A new study by Wetlands International, The Nature Conservancy and the University of Cambridge, concludes that mangrove conservation and restoration in areas close to human populations will render the greatest return on investment with respect to enhancing fisheries.

Kajian Lingkungan dan Sosial Ekonomi dalam Perencanaan Program Rehabilitasi dan Pemberdayaan Masyarakat di Gampong Layeun

Pada Juli 2014, Wetlands International diundang Clinton Global Initiative (CGI) untuk bersama-sama memikirkan dan berkontribusi dalam pemulihan mata pencaharian masyarakat desa Layeun. Pada pertemuan yang dihadiri Presiden Clinton, CGI berkomitmen memberikan bantuan berupa 12 unit kapal tangkap. Di saat yang sama, Wetlands International juga berkomitmen untuk memfasilitasi masyarakat melakukan kegiatan pemberdayaan ekonomi yang diintegrasikan dengan restorasi pesisir. Kedua program ini diharapkan mampu bersinergi agar dapat memberikan dampak yang lebih signifikan bagi pemulihan perekonomiam masyarakat dan lingkungan pesisir.
