Study of the variation trend, abrupt behavior and relationship between climate and planting structure in a cold region of China: a case study of Heilongjiang Province
Climate change has changed planting structure greatly in cold regions. Studies are needed that understand the relationship between climate change and agriculture in cold regions and to serve as references for studies of the impact of climate change on agriculture in similar areas. This paper uses Heilongjiang Province as a case study; seven test methods and mutual information were used to ...

Central Asian irrigation sector in a climate change context: some reflections
According to expert opinion, the Central Asian region is likely to experience climate-induced changes with the irrigation sector being the most vulnerable to any change. Climate change impacts are interconnected with land use and socio-economic changes, and many other processes of a human–environmental system. Assessment and adequate information sharing play a critical role in decision ...

Climate, vulnerability and farming: a preliminary study among Australian food growers
The present study examines climate change, vulnerability to climate, and other environmental challenges from the perspective of 80 horticulture operators from different Australian states. Vulnerability in the form of storms and droughts are respondents’ main environmental concerns; in some cases, the impact of wildlife displacement is affecting their production outputs. In addition, substantial ...

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 ...

Impacts of climate change on irrigation water requirements for rice–wheat cultivation in Bagmati River Basin, Nepal
This study highlights the spatial and temporal impacts of climate change on rice–wheat cropping systems, focusing on irrigation water requirement (IWR) in the Bagmati River Basin of Nepal. The outputs from a general circulation model (HadCM3) for two selected scenarios (A2 and B2) of IPCC and for three time periods (2020s, 2050s, and 2080s) have been downscaled and compared to a baseline ...

Assessment of climate change impacts on irrigation water requirement and rice yield for Ngamoeyeik Irrigation Project in Myanmar
This study analyzes the impacts of climate change on irrigation water requirement (IWR) and yield for rainfed rice and irrigated paddy, respectively, at Ngamoeyeik Irrigation Project in Myanmar. Climate projections from two General Circulation Models, namely ECHAM5 and HadCM3 were derived for the 2020s, 2050s, and 2080s. The climate variables were downscaled to basin level by using the ...

Changes in water demands under adaptation actions to climate change in an irrigation district
Climate change will affect the water balance of irrigated agriculture. Therefore, farmers and irrigation managers should consider adapting to new scenarios. Changes in water demands in a Mexican irrigation district were studied using an irrigation-scheduling model. The impact on water demands of two potential adaptation actions, adjusting planting season and using longer-season varieties ...

Evaluation of climate change impacts and adaptation strategies for maize cultivation in the Himalayan foothills of India
This study evaluates the impacts of climate change on rainfed maize (Zea mays) yield and evaluates different agro-adaptation measures to counteract its negative impacts at Sikkim, a Himalayan state of India. Future climate scenarios for the 10 years centered on 2025, 2055 and 2085 were obtained by downscaling the outputs of the HadCM3 General Circulation Model (GCM) under for A2 and B2 ...

Modeling the impacts of increase in temperature on irrigation water requirements in Palakkad district: a case study in humid tropical Kerala
Rise in temperature is one of the predicted impacts of climate change with significant implications on water resources management. An attempt has been made to calculate the water requirement of crops in different agro-ecological zones of Palakkad district in humid tropical Kerala using the CROPWAT 8.0 model. Sensitivity analysis was done for a simulated rise in temperature from 0.5 to 3.0 ...

Stocks, Chemistry, and Sensitivity to Climate Change of Dead Organic Matter Along the Canadian Boreal Forest
Abstract Improving our ability to predict the impact of climate change on the carbon (C) balance of boreal forests requires increased understanding of site-specific factors controlling detrital and soil C accumulation. Jack pine (Pinus banksiana) and black spruce (Picea mariana) stands along the Boreal Forest Transect Case Study (BFTCS) in northern Canada have similar C stocks in aboveground ...

Projection of future climate change impacts on nonpoint source pollution loads for a forest dominant dam watershed by reflecting future vegetation canopy in a Soil and Water Assessment Tool model
This study is to assess the future impact of climate change on hydrological behavior considering future vegetation canopy prediction and its propagation to nonpoint source pollution (NPS) loads. The SWAT (Soil and Water Assessment Tool) model was used for the assessment. For a forest dominant ChungjuDam watershed of South Korea, the MIROC3.2hires climate data of SRES A1B and B1 scenarios were ...

Assessment of climate change impact on crop yield and irrigation water requirement of two major cereal crops (rice and wheat) in Bhaktapur district, Nepal
Rice and wheat are major cereal crops in Nepal. Climate change impacts are widespread and farmers in developing countries like Nepal are among the most vulnerable. A study was carried out to assess the impact of climate change on yield and irrigation water requirement of these cereal crops in Bhaktapur, Nepal. Laboratory and soil-plant-air-water analysis showed silt-loam being the most ...

Using Technology to cut carbon emissions and improve agriculture
Greenhouse gases from agriculture account for more than 10% of total emissions globally, roughly equivalent to the entire global transport sector. Meanwhile, it is estimated that agricultural production will need to increase by about 70% by 2050 to keep pace with global population growth. What’s more, the real impacts of climate change on the agricultural ...
