  • The localization of agriculture

    In the United States, there has been a surge of interest in eating fresh local foods, corresponding with mounting concerns about the climate effects of consuming food from distant places and about the obesity and other health problems associated with junk food diets. This is reflected in the rise in urban gardening, school gardening, and farmers’ markets. With the fast-growing local foods ...

  • Soil water recharge for grassed and forested land covers on the Oak Ridges Moraine, southern Ontario, Canada

    Soil water recharge (R) below 1 m depth was estimated via a 1-d water balance for grasslands, hardwood stands and red pine plantations on the Oak Ridges Moraine (ORM) in southern Ontario, Canada. Annual R values (431–696 mm) were in the order of previous estimates for outcropping sands and gravels on the ORM (∼400 mm); however, they only partially supported hypothesized ...

  • Land accounts for Europe 1990-2000

    Changes in land cover in Europe reflect modifications in the uses of land, which often compete for the same resource: development of artificial surfaces for housing, transport and economic activities; intensification or extensification of agriculture practices; conversion of natural land to agriculture or farmland abandonment; afforestation or deforestation. Accounting for land cover change in a ...

  • Soil Management for Sustainable Agricultural Productivity in Bangladesh

    Introduction: The 'rules of road' by which agricultural researchers measure the impact of their work are being restudied. The first conclusion is that it is impossible to choose between food needs of today and food needs of 100 years from now. Somehow the food ...

  • “Swapping Land” to Produce Sustainable Palm Oil in Indonesia

    Indonesia has the world’s third-largest rainforest, which is a haven for biodiversity and an economic lifeline for many rural communities. However, Indonesian forests are in rapid decline and the country regularly tops deforestation hotspots lists. The key to protecting Indonesia’s forests remains ...

  • Mapping of forest cover and assessment of ecosystems and ecosystem services related to local livelihoods

    The municipality of Santa Cruz del Quiché, located in the Quiché Department of Guatemala, is characterized by degraded natural resources and a population highly vulnerable to climate change impacts. As part of the Partners for Resilience programme, Guatemalan Red Cross and Wetlands International conducted a study to map the forest cover and ecosystems of the Cucubá river ...

  • 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) ...

  • The Chilean Water Allocation Mechanism, established in its Water Code of 1981

    A long narrow strip of land (no more than 430 km wide) between the Andes and the Pacific Ocean, Chile stretches 4,630 km from near lat. 18°S to Cape Horn (lat. 56°S), including at its southern end the Strait of Magellan and Tierra del Fuego, an island shared with Argentina. In the Pacific Ocean are Chile's several island possessions, including Easter Island, the Juan Fernández ...

  • Valuation of nitrogen retention as an ecosystem service on a catchment scale

    An ecosystem service approach was used to study the water purification service exemplified by impacts of land management scenarios. Nitrogen retention was calculated in two agricultural catchments by the dynamic Integrated Nutrients in Catchments (INCA)-N model. The monetary valuation was based on purification efficiency of artificial wetlands. The set of scenarios were based on existing ...

  • Detection of biotic responses to urbanization using fish assemblages from small streams of western Georgia, USA

    We examined relationships between stream fish assemblages and land use alteration associated with urbanization in 15 lower Piedmont watersheds along an urbanization gradient north of Columbus, western Georgia. Based on land cover data from 2002 Landsat 7 TM imagery aerial photos, streams drained watersheds that were largely urban, developing (suburban), agricultural (pasture), managed pine ...

  • Corn and soybean mapping in the united states using modis time-series data sets

    Monitoring and mapping of U.S. croplands has long been a primary goal of many users of earth observation satellite data. The advantages of using low spatial and high temporal resolution data are (i) increased ability to monitor the phenological change of crop plants, and (ii) the possibility of generating consistent large area crop cover maps. This study investigates the potential of 500-m MODIS ...

  • Interactive Forest Atlas of Equatorial Guinea

    The synthesis document of the Interactive Forest Atlas of Equatorial Guinea (V1.0) gives an overview of the forest sector in Equatorial Guinea through 2013. It starts with a discussion of forest legislation and follows with information about land use allocation and land cover types in the National Forest Reserve through July 2013. Amongst others, the Interactive Forest Atlas of Equatorial Guinea ...

  • Farmers' (local and colonists) perceptions of environmental changes in the forest frontier of the upper Amazon, Peru

    Amazon ecosystem degradation profoundly impacts life supporting processes of global importance such as climate regulation, as well as local conditions for livelihoods. In Peru's highland jungle, an expanding deforestation front of forest conversion to agriculture has vastly transformed the landscape. Small–scale farming, the main driver of forest degradation, and consequently household natural ...

  • Flood risk for farmer and dyke relocation

    The Biosphere Reserve Lower Saxonian Elbe Valley (Biosphärenreservat Niedersächsische Elbtalaue), which was created on the basis of an unanimous decision by the Lower Saxonian State Parliament in 2002, represents Lower Saxony’s contribution to the UNESCO Biosphere Reserve ‘Flusslandschaft Elbe’ (Elbe River Landscape). It stretches for about 100 kilometres south-east of ...

  • Riparian woody plant diversity and forest structure along an urban-rural gradient

    Changes in riparian woody plant assemblages are anticipated in the southeastern United States due to increases in urbanization rates. Because riparian forests serve important roles in maintaining water quality and biodiversity, understanding how they respond to urbanization is crucial. The objective of this study was to examine forest structure and woody vegetation diversity indices of riparian ...

  • Losing Soil

    In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

  • Agroforestry Mitigates Climate Change

    Climate changes, as one of the biggest threats to a global food security, highly influence natural resources that are essential for crop production. Farming is not only affected by the impact of climate changes, but it’s also a significant contributor to global greenhouse gas emissions. Intensive farm practices that include both farm production and change of land use, directly affect the ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Zimbabwe`s New Farmers Fail to Deliver

    HARARE, Zimbabwe, (ENS) - Six years after President Robert Mugabe sanctioned violent invasions of Zimbabwe's commercial farmland - mostly but not entirely white owned - by landless peasants, the facts show that the so-called new farmers have failed dramatically to produce crops to feed their countrymen. The poor peasants who led the invasions, at the behest of Mugabe, have ...
