  • Delta Drainage and Irrigation System - Case Study

    Background Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) watershed, ...

  • Relationship between Riparian Vegetation and Stream Benthic Communities at Three Spatial Scales

    We examined the influence of riparian vegetation on macroinvertebrate community structure in streams of the Upper Thames River watershed in southwestern Ontario. Thirty-three µ-basins (129–1458 ha) were used to identify land cover variables that influenced stream macroinvertebrates. Micro-basins represented the entire drainage area of study streams and were similar in stream order (first, second) ...

  • Rajang Delta threatened by floods

    This paper presents a case study of the Rajang Delta in Sarawak, Malaysia where peatland subsidence will cause flooding, rendering more than half of the Rajang Delta unsuitable for any agriculture cultivation due to severe floods in 50 years. The land area which will be inundated is 3 times the size of Singapore!! What a great loss! Case study summary: The case study reveals that ...

  • Towards climate-responsible peatlands management

    Peatlands are lands with a naturally accumulated peat layer at their surface. They are found all over the world and come in many forms, display many different characteristics and are used in many different ways. Even though peatlands extend over a relatively small portion of the earth’s land surface, they hold a large pool of carbon. There is no universal definition of peatlands. For the ...

  • Nutrient transport characteristics of livestock manure in a farmlan

    Background :Livestock excretions containing high concentration of nutrient, pig liquid fertilizer, and cattle manure were applied to agricultural land. The characteristics of nutrient transport were examined in surface runoff and groundwater by an artificial rainfall event at real scale field site. Also, the effects of the artificial rainfall event on the characteristics of residual soil after ...

  • Social and biophysical impacts of watershed development programmes: experiences from a micro-watershed area in India

    Rainwater conservation and soil erosion prevention are vital for the economic and financial sustainability of dry land agriculture. An integrated watershed development programme is thus a means of achieving these goals. Presently, integrated watershed management is receiving worldwide recognition as an effective model for watershed planning. A watershed is considered the basic geographical ...

  • Environmental and social impacts of oil palm cultivation on tropical peat

    The palm oil sector has created in the past few decades millions of jobs. Over the next decade, the Indonesian government plans to double the annual production of palm oil, creating new jobs for an estimated 1.3 million households. Although the cultivation of oil palm on peatlands creates new income opportunities for many farmers in the short term, longer term economic implications remain ...

  • Going organic for the climate

    Also in the world of climate change, organic is the way to go. I am not writing about organic food here, despite my personal interest in the topic, but about peatlands, which are soils with a substantial layer of organic matter at or near the surface. Well, they are the way to go for the climate as long as you treat them well. If not, they become a vigorous source of greenhouse gas emissions. ...

  • Profitability maps as an input for site-specific management decision making

    For over a decade, farmers have been collecting site-specific yield data. Many have formed doubts about this investment because of their inability to directly apply this information as feedback for improving management. The objective of this case-study analysis was to investigate how site-specific decisions can be improved by transforming a long-term multiple-crop yield-map dataset into profit ...

  • Soy Cultivation in South America

    The expansion of soy bean Soy cultivation has shown an increasing expansion throughout Argentina, Brazil, Bolivia and Paraguay, in the last decade. This remarkable increase is explained by its economical importance in the region, and as a consequence, it is difficult to regulate its progress and attenuate its potential socio-environmental impacts. In 2012, in these 4 countries the ...

  • Learning from past civilizations

    To understand our current environmental dilemma, it helps to look at earlier civilizations that also got into environmental trouble. Our early twenty-first century civilization is not the first to face the prospect of environmentally induced economic decline. The question is how we will respond. As Jared Diamond points out in his book Collapse, some of the early societies that were in ...

  • Why Drip Irrigation Design is Crucial to Your Success

    Drip irrigation is one of the most cost-effective and efficient watering methods in agriculture. It has become incredibly popular in the past 50-years and has been widely adopted by agriculturalists in dozens of countries throughout the world. In simple term, drip irrigation works by sending water through plastic pipes into drip emitters. These emitters are specifically designed to release water ...
