  • 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. ...

  • The Effect of Off-farm Work on the Intensity of Agricultural Production

    Changes in agricultural production methods have been associated with environmental pressure and a loss of natural habitats. This paper explores the extent to which farmer participation in off-farm work (an increasing phenomenon in most developed countries) changes the intensity of agricultural input use focusing, in particular, on fertilizer and crop protection product use. A sample selection ...

  • Field degradation of aminopyralid and clopyralid and microbial community response to application in Alaskan soils

    High latitude regions experience unique conditions that affect the degradation rate of agrochemicals in the environment. In this study, data collected from two field sites in Alaska (Palmer and Delta) were used to generate a kinetic model for aminopyralid and clopyralid degradation and to describe the microbial community response to herbicide exposure. Field plots were sprayed with herbicides ...

  • 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 ...

  • Assessing agroforestry`s advantages

    Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only ...

  • Climate and Economic Benefits of Agroforestry Systems

    Introduction Agriculture is well known as a significant contributor to global greenhouse gas emissions, but emerging practices in land management have the potential to curtail these emissions and reverse much of the ecological and climate harm caused by overly intensive systems. One such practice, cultivation and conservation of trees in agricultural practices, or agroforestry, is an important ...

  • Chemical composition and mammary cancer inhibitory activity of dry bean

    The global economic burden caused by chronic diseases such as diabetes, heart disease, and cancer is enormous. Little information exists about the role that specific crops in the diet play to reduce these diseases. To address this question, the phenolic and flavonoid contents, oxygen radical absorbance capacity (ORAC), and anticancer activity of six market classes of dry bean (Phaseolus vulgaris ...

  • Recovery based on plot experiments is a poor predictor of landscape‐level population impacts of agricultural pesticides

    Current EU regulatory risk assessment allows application of pesticides provided that recovery of non‐target arthropods in‐crop occurs within a year. Despite long‐established theory of source sink dynamics, risk assessment ignores depletion of surrounding populations and typical field trials are restricted to plot‐scale experiments. Here, we use agent‐based modelling of 2 contrasting ...

  • Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment

    Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

  • The Importance of Scales in the Agricultural & Farming Industry

    Weighing scales are essential and necessary equipment required for a wide range of applications. Whether intended for personal, industrial or commercial use, they serve one important function – providing accurate weight measurements for varied loads. In the agricultural sector, scales are indispensable tools and without them, it would be almost impossible to manage farms or carry out trade! ...

  • Can superfoods boost the planet’s health, too?

    As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, ...

  • Surprising ways Kenyans are embracing climate-smart agriculture

    In rural Kenya, where it may only rain twice per year, farmers and herders are embracing so-called “climate-smart” agriculture. The video above, produced by the World Bank, begins by showing how John and Mary Obuom have transformed their one-acre farm into a model of sustainable practices. The family plants a diversity of crops in case one or more fails in a given year. A thicket of ...

  • Downstream Voices - Wetland Solutions to Reducing Disaster Risk

    Until recently, the world’s response to inevitable climate change was based on producing ever more precise forecasts of what would happen locally – running ever more sophisticated climate models to generate data on the climate in Bamako, Mali in 2040, for instance – and then working out how to “adapt” to the change. While ever bigger super-computers with ever more ...

  • New tools and farmer training could revolutionize pesticide management in West Africa

    Field schools that train farmers in alternative methods of pest control have succeeded in nearly eliminating the use of toxic pesticides by a community of cotton growers in Mali, according to a new FAO study published today by the London-based Royal Society. The study was conducted in two areas - the Bla ...

  • How good is GLASOD?

    The Global Assessment of Soil Degradation (GLASOD), commissioned 20 years ago by the UN Environment Program (Oldeman et al., 1991), collated expert judgments of many soil scientists to produce a world map of human-induced soil degradation. It has been an important source for national and international environmental policy decisions but has been criticized on the grounds that its qualitative ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • Carbon Sequestration: Addressing Climate Change and Food Security through Sustainable Agriculture

    Introduction To meet the demands of a growing, increasingly urban global population (approximately 9 billion by 2050), the World Bank calculates that global food production must increase by 70% in the next 35 years. This is a great challenge not only because of the volume of food that must be produced, but because agricultural conditions will not remain constant or predicable ...
