“…To complete this work, it would be necessary to introduce, as STICS inputs, variations in other climatic factors (rainfall and radiation) and predictions of increased [CO 2 ] levels. Indeed, rainfall may be a determinant factor in mountain forage systems without irrigation and for forage drying in the field [11]. In parallel with introducing rainfall parameters, the cutting date could be calculated within STICS as a function of no-rain days after cutting, which also increases forage conservation time.…”

Impact of global warming on the growing cycles of three forage systems in upland areas of southeastern France

-The simulations supplied by a combination of a global climate model and a weather generator allowed the creation of two climate scenarios including an increase and/or monthly variations in temperature for the 2070-2100 horizon, which were compared with two currently available series (1961-1990 and 1990-2000). Three forage systems applied in upland areas of southern France were simulated using the STICS model (silage maize, perennial alfalfa and grasses) and the outputs were introduced into a digital elevation model. We noted changes in precocity which allowed the sowing of silage maize varieties with longer crop cycles at lower altitudes and an enlargement of the crop zone above 700-800 m. When introducing monthly temperature variations, we observed major frost damage which decreased maize yields. As for gramineous and alfalfa grasslands, we obtained a lengthening in the growing period with earlier first cut dates and sometimes the possibility of a supplementary cut.climatic change / silage maize / alfalfa, gramineous / upland area / crop model

“…However, an increase in temperature during crop development will depress yields in those regions where summer temperature and water stress are already limiting factors for plant growth (Rosenzweig & Tubiello 1997). Similarly, higher rainfall can enhance grass growth in regions where water is a limiting factor, but it will be detrimental on grazing and grass conservation in areas with poor water drainage due to water logging (Cooper & McGechan 1996). This regional variation of the impact of climate change on agricultural production eventually leads to differences in farms’ responses to such change in different regions (Mendelsohn et al 1996; Bryant et al 2000; Tan & Shibasaki 2003; Seo & Mendelsohn 2008; Walker & Schulze 2008; Nelson et al 2009, 2010; Ciscar et al 2013; Shrestha et al 2013; Witzke et al 2014).…”

Irish farms under climate change – is there a regional variation on farm responses?

et al. 2014

The current paper aims to determine regional impacts of climate change on Irish farms examining the variation in farm responses. A set of crop growth models were used to determine crop and grass yields under a baseline scenario and a future climate scenario. These crop and grass yields were used along with farm-level data taken from the Irish National Farm Survey in an optimizing farm-level (farm-level linear programming) model, which maximizes farm profits under limiting resources. A change in farm net margins under the climate change scenario compared to the baseline scenario was taken as a measure to determine the effect of climate change on farms. The growth models suggested a decrease in cereal crop yields (up to 9%) but substantial increase in yields of forage maize (up to 97%) and grass (up to 56%) in all regions. Farms in the border, midlands and south-east regions suffered, whereas farms in all other regions generally fared better under the climate change scenario used in the current study. The results suggest that there is a regional variability between farms in their responses to the climate change scenario. Although substituting concentrate feed with grass feeds is the main adaptation on all livestock farms, the extent of such substitution differs between farms in different regions. For example, large dairy farms in the south-east region adopted total substitution of concentrate feed while similar dairy farms in the south-west region opted to replace only 0·30 of concentrate feed. Farms in most of the regions benefitted from increasing stocking rate, except for sheep farms in the border and dairy farms in the south-east regions. The tillage farms in the mid-east region responded to the climate change scenario by shifting arable production to beef production on farms.

Determination of available workdays of a tractor for field operations is very significant in design, development, and selection of efficient machinery systems for agricultural operations. Available workdays vary and generally based on average daily temperature and amount of precipitation. In this study, an excel program was developed to determine the available workdays of a tractor in field operations. Available workdays of a tractor over the Southeastern Anatolia Project (Turkish: Güneydoğu Anadolu Projesi, GAP) region, opened for irrigation in 1995, were calculated with this software by using the meteorological data of the region. Results indicated significant changes in available workdays from east-to-west and north-to-south. Considering the 15 days period, maximum number of work days corresponds only 33% of the total period in April.
