A methodological system for hydraulic heritage assessment: a management tool
Traditional irrigation systems are spatial units with a remarkable cultural and heritage value, which in turn generate water landscapes. They are part of hydraulic heritage, which includes material, ideational and symbolic assets. However, the assets related to historical irrigation systems and their landscape units have been poorly studied and evaluated. This paper develops a methodological ...

The role of a hybrid phytosystem in landscape water purification and herbicides removal
The performance of a hybrid phytosystem in landscape water purification and herbicides removal was investigated. The phytosystem operating in an arboretum is located in the Minhang Campus of Shanghai Jiao Tong University, China. The phytosystem is composed of two purification stages: sedimentation Stage 1 without external air supply; and Stage 2 with an external air supply. Stage 2 is also ...

Losing fertile matter to the sea: How landscape entropy affects climate
Under natural conditions order is created by interactions between water, temperature, chemical gradients, ground surface, and organisms. However, in the 'developed' landscape, order is replaced by randomness. The de-coupling of energy and water cycles is observed in eutrophication, as irreversible matter losses break closed metabolic cycles in coenotic structures. Another cause of landscape ...

Funding for forests: the potential of public ballot measures
A variety of measures exist to prevent deforestation or forest conversion to other land uses. Some of these measures, such as purchasing land outright for conservation or purchasing conservation easements, are designed to permanently protect forests by precluding future residential or commercial development on the tract of land. But these approaches all require money. One approach to raising ...

Re-coupling the carbon and water cycles by Natural Sequence Farming
The techniques of Natural Sequence Farming (NSF) were developed during hands-on management of degraded farmland in the Upper Hunter Valley region of Australia. Early settlement of the continent by people with European cultural assumptions disrupted established interactions of water, soil, and plants resulting in lost fertility. Moreover, agricultural practices such as clearing, burning, ...

Critical source area management of agricultural phosphorus: experiences, challenges and opportunities
The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

Environmental impacts of community-based forest management in the Philippines
Community-based forest management (CBFM) is a major strategy in managing forest lands in the Philippines. Forest and land management activities implemented in CBFM project sites include management of tropical forests (enrichment planting, timber stand improvement or TSI and limited harvesting), rehabilitation of degraded lands (reforestation, assisted natural regeneration (ANR)) and agroforestry. ...

Irrigating with reclaimed water through permanent subsurface drip irrigation systems
ABSTRACT In Hawaii, reclaimed water has been used in agricultural irrigation and the irrigation of golf courses and other large landscaped areas. However, the Hawaii Department of Health's new "Guidelines for the Treatment and Use of Reclaimed Water" published in November 1993, limits uses of reclaimed water through overhead sprinkler irrigation systems. The subsurface drip irrigation concept ...

Aquarium of Novice, How to Set Up a Low Tech Planted Tank?
More and more people like to make an aquarium landscape, but they do not know the specific steps, have been afraid to try this! Today, we will tell you a brief introduction about the process of novice landscape. First of all, prepare a 60*45*45 fish tank. It is best to use fish tank filter box, which flow is up to 600L per hour, set up LED water grass fish tank light is the best. If you want to ...

Water reuse through subsurface drip irrigation systems
Water reuse in Hawaii has been primarily relegated to agricultural irrigation and irrigation of golf courses and other large landscaped areas. The continuing effort to conserve and preserve potable water resources emphasizes using alternative water sources for irrigation. Agriculture, golf courses, highways, parks, playgrounds and cemeteries are among the heaviest users of irrigation water due to ...

Unearthing a sustainable soil health strategy
Most farmers can agree that although there’s no silver bullet to a bumper crop, healthy soil plays a crucial role, from seeding to harvest and beyond. But how much is understood about what really happens beneath the surface of the field? “Well-functioning soil will retain, provide and recycle nutrients and water, and will support a diverse array of biota in the soil-plant ...

Impact of Agri-environment measures
The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...

Soil and water: towards a larger-scale perspective of their relations
Land use changes over time have altered relations between soils and water cycles throughout Europe. There are regions where forests were cut for agriculture or herding, or for industrial, mining, and/or railroad use. Soils were lost, through mud floods, and the water cycles changed so that their present status is one of badlands and/or desert-like areas. Early stages in the path to degradation ...
