Climate change is the major factor that affects crop yield and productivity in the long term. The changing climate scenario is now impacting farmers’ lands and their outcomes in both developed and developing countries. The intercropping of crop species or varieties that have high arable capability is a promising technique for increasing crop production without increasing agricultural inputs. In intercropping, the selection of varieties, optimum sowing time, method of plant arrangement, and sowing proportion are required to make the design suitable for an intercropping system. Intercropping is one of the most highlighted agronomic practices helping to improve soil health (structure, …

Weather Information And Decision-Support Tool Needs Assessment, Lily Calderwood, Glen Koehler, Sean Birkel, Erin H. Roche
The Journal of Extension
University of Maine researchers developed three commodity-specific grower focus groups (lowbush blueberry, apple, mixed vegetable) to discuss and survey 1) current access to weather information, and 2) interest in weather-based decision support tools. NOAA National Weather Service (30%) (n=47) was most commonly cited as a weather information source. Growers ranked greater forecast accuracy (31%) and localization (19%) (n=48) as highest priorities. Only 34% of growers reported current use of weather-based decision support tools, but 86% expressed interest in future use (n=134). The project team is using grower input to improve weather data access and decision-support tools for Maine farmers.

Short-Term Changes Of Leaf Area Index, Light Transmission, And Gap In A Temperate Mixed Deciduous Forest Ecosystem In Bartın, Turkey, İlyas Bolat, Ömer Kara, Meli̇h Öztürk
Turkish Journal of Agriculture and Forestry
In this study, leaf area index (LAI), light transmission, and gap were estimated by using the hemispherical photograph analysis technique with Hemisfer software version 1.5.3 for a temperate mixed deciduous forest. The height of the overall vegetation in the stand ranged from 15 to 20 m, and the diameters of the trees in the stand at breast height varied between 14 and 28 cm. This study showed that the mean value of LAI increased by 4% in the 5-year period from 2007 to 2012. LAI was significantly (P < 0.05) greater in 2012 than in 2007, whereas the mean percentage of light transmission was significantly lower in 2012 than it was in 2007. In addition, there was a significant (P < 0.01) correlation between LAI and light transmission, and there was also a statistically significant correlation between the gap and light transmission (P < 0.05). According to long-term meteorological data (1982-2012), this study also demonstrated that the mean air temperature rose approximately 1.0 °C between 2007 and 2012. Consequently, this study indicated that LAI varies with respect to time and the increase of LAI leads to a decrease in light transmission. Additionally, the air temperature and precipitation have a significant influence on the LAI.

Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis
Journal of Environmental and Resource Economics at Colby
The global agriculture sector is responsible for close 20% of the aggregate anthropogenic greenhouse gas (GHG) emissions emitted since the start of the industrial age. Much of these emissions are attributed to the degradation of soils due to land use change when native ecosystems were converted to agricultural fields. Soil organic carbon (SOC) has been found to decrease in temperate soils when the native (such as a forest or grassland) ecosystem is replace by croplands. The aggregate amount of organic carbon stored in soils globally is estimated be 3.3x the size of the atmospheric carbon pool. Further soil degradation and …

Global Perspectives On First Generation Liquid Biofuel Production, Rok Fink, Saso Medved
Global Perspectives On First Generation Liquid Biofuel Production, Rok Fink, Saso Medved
Turkish Journal of Agriculture and Forestry
Transport today is mostly sustained by liquid fossil fuels, despite the fact that the invention of the combustion engine started with biofuels. However, known environmental impacts and the instability of the fossil-fuel market have revived the status of biofuels. Some concerns have appeared regarding how emerging global climate changes will affect biofuels' feedstock production, since agriculture is strongly dependent on climate variables. Therefore, numerical models were introduced to calculate how temperature and precipitation could affect crop production for biodiesel and bioethanol production. Furthermore, 4 scenarios projected by the Intergovernmental Panel on Climate Change were put into the calculations. The results …

Cultural Responses To Climate Change In The Holocene, Richard Prentice
Anthós
Variable Holocene climate conditions have caused cultures to thrive, adapt or fail. The invention of agriculture and the domestication of plants and animals allowed sedentary societies to develop and are the result of the climate becoming warmer after the last glaciation. The subsequent cooling of the Younger Dryas forced humans to concentrate into geographic areas that had an abundant water supply and ultimately favorable conditions for the use of agriculture and widespread domestication of plants and animals. Population densities would have reached a threshold and forced a return to foraging, however the end of the Younger Dryas at 10,000 BP …
