  • Changing climate changes soils

    Varied predictions for soil organic matter as climate changes The hottest months. The snowiest winters. Catastrophic floods and droughts. Climate change impacts lives across the world in drastic and unpredictable ways. This unpredictability also extends to the more subtle – yet still important – effects of climate change. For example, it is ...

  • Adaptation of pulse crops to the changing climate of the northern great plains

    Climate over the northern Great Plains has generally warmed over the last 60 yr. The rate of warming has varied temporally and spatially, confounding trend analysis for climate indicators such as increased length of the growing season. Change in precipitation has been even more variable. Despite this variability, present-day trends in temperature and precipitation generally coincide with the ...

  • 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 ...

  • A matter of keeping the litter dry

    Asger Petersen from the marshland in the southwestern corner of Denmark has been producing chickens for nearly twenty years. Eight years ago Asger changed to organic with outdoor runs. From consultant to farmer For many years I was a consultant in the Danish poultry industry. My trade was feed formulation. Since I became a poultry farmer myself, I have seen a lot of changes ...

  • Effects of changes in climatic variables on maize crop water requirements in Huang–Huai–Hai watersheds, China

    The study of crop water requirements (CWR) under climate change is critical for reasonable crop irrigation. In the present study, the effects of changes in climatic variables from 1961 to 2010 on maize CWR in Huang–Huai–Hai (HHH) watersheds in China were investigated. Five daily climatic factors including maximum temperature (Tmax), minimum temperature ...

  • Mitigating climate change through oil palm cultivation

    Oil palm requires 7-11 times less land area than soyabean, rapeseed and sunflower to produce the same amount of oil. Therefore, the use of palm oil for food and biofuel, has saved 97-159 million ha of land from being deforested for cultivation with lower yielding oil crops. This has avoided 27-45 billion tonnes of carbon dioxide (CO2-e) emissions. Oil palm also sequesters eight times more CO2 ...

  • Agricultural research `key to easing climate-change impacts`

    Agricultural research should be a strategic priority of the UN's efforts to lessen the impacts of climate change, according to a report launched at a UN climate change conference in Doha, Qatar. The report, released by a group of leading international experts in climate change and agriculture last month (30 ...

  • 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. ...

  • A call to conserve crops’ wild cousins

    Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Trend analysis in reference evapotranspiration and aridity index in the context of climate change in Togo

    Reference evapotranspiration is a key parameter in hydrological and meteorological studies and used to determine the actual water use rate for various crops. The objectives of this study were to explore trend in the grass-reference evapotranspiration (ETo) through years 1961–2011 and to identify trend in the aridity index as an indicator of change in climate in Togo. ETo was calculated using ...

  • The impact of climate change and soil salinity in irrigation water demand on the Gaza Strip

    The presented work analyzes the potential impacts of the temperature, precipitation changes and water salinity on agricultural water demand. The study was carried out on five representative orchard crops (olive, palm, grapes, citrus and guava) that cover around 83% of the orchard farms in Gaza Strip. To achieve this goal, CropWat modeling software version 8.0 is used to calculate the ...

  • Impact on Australia and Pacific Islands of climate change due to enhanced greenhouse effect

    Climate in any particular region of the Earth can change due to many factors. Potentially one of the most significant is changes in atmospheric concentration due to increased emission of greenhouse gases. This could lead to significant changes in temperature and precipitation on a regional basis with significant effects on regional economies and societies. Potential impacts on Australia are ...

  • Accounting for adaptation in assessing impact of climatic variations on crop yields: an empirical study of Arizona

    The goal of this paper is to analyze the impacts of climatic variation around current normals on crop yields and explore corresponding adaptation effects in Arizona, using a unique panel data. The empirical results suggest that both fertilizer use and irrigation are important adaptations to climate change in crop production. Fertilizer use has a positive impact on crop yields as expected. When ...

  • 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 ...

  • Burkina Faso farmers lead the way on food security and climate change resilience

    If you want to know how to grow crops in the face of climate change, drought, and land degradation, ask Ousséni Kindo, Ousséni Zoromé, or Yacouba Sawadogo—three farmers in Burkina Faso’s Yatenga region. Policy makers, researchers, and NGO representatives gathered earlier this year at ...

  • Analysing the links between agriculture and climate change: can 'best management practices' be responsive to climate extremes?

    Rural communities the world over depend on agriculturally–based livelihoods. In the Canadian prairies, access to sufficient quality and quantity of water can be challenging. Agriculture is fundamentally susceptible to access to water during critical crop germination and growth periods. Climate change models for the Canadian prairies indicate, in general, that summer growing seasons will ...

  • Can genetic engineering help quench crops’ thirst?

    Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close ...

  • Irrigation water requirements for seed corn and coffee under potential climate change scenarios

    The impact of potential future climate change scenarios on the irrigation water requirements (IRRs) of two major agricultural crops (coffee and seed corn) in Hawai'i was studied using the Irrigation Management System (IManSys) model. In addition to IRRs calculations, IManSys calculates runoff, deep percolation, canopy interception, and effective rainfall based on plant growth parameters, site ...
