SUMMARYDue to the potential impact of climate change and climate variability on rainfed production systems, both farmers and policy makers will have to rely more on short- and long-term yield projections. The goal of this study was to develop a procedure for calibrating the Cropping System Model (CSM)-CROPGRO-Soybean model for six cultivars, to determine the potential impact of climate change on rainfed soybean for five locations in Georgia, USA, and to provide recommendations for potential adaptation strategies for soybean production in Georgia and other south-eastern states. The Genotype Coefficient Calculator (GENCALC) software package was applied for calibration of the soybean cultivar coefficients using variety trial data. The root mean square error (RMSE) between observed and simulated grain yield ranged from 201 to 413 kg/ha for the six cultivars. Generally, the future climate scenarios showed an increase in temperature which caused a decrease in the number of days to maturity for all varieties and for all locations. This will benefit late-planted soybean production slightly, while the increase in precipitation and carbon dioxide (CO2) concentration will result in a yield increase. This was the highest for Calhoun and Williamson and ranged from 31 to 49% for the climate change projections for 2050. However, a large reduction in precipitation caused a decrease in yield for Midville, especially based on the climate scenarios of the Global Climate Models (GCMs) Commonwealth Scientific and Industrial Research Organisation's model CSIRO-Mk3.0 and Geophysical Fluid Dynamics Laboratory's model GFDL-CM2.1. Overall, Calhoun, Williamson, Plains and Tifton will probably be more suitable for rainfed soybean production over the next 40 years than Midville. Farmers might shift to a later planting date, around 5 June, for the locations that were evaluated in the present study to avoid potential heat and drought stress during the summer months. The cultivars AG6702, AGS758RR and S80-P2 could be selected for rainfed soybean production since they had the highest rainfed yields among the six cultivars. In general, the present study showed that there are crop management options for soybean production in Georgia and the south-eastern USA that are adapted for the potential projected climate change conditions.

The Impact

Purpose Farmers' adaptation strategies in agricultural production are required to minimise the negative impact of climate change on a nation's food production in developing countries. Based on the panel data of the provincial level in China from 2000 to 2017, this study aims to analyse the changing climate over recent years and farmers' adaptation strategy in terms of cropping in agricultural production. Design/methodology/approach This study uses Simpson's diversity index (SDI) to measure the degree of crop diversity planted by farmers and evaluate the influence of climate change on farmers' cropping strategy using the fixed-effect model. Further, the authors estimate the impact of farmers' cropping strategy on their economic performances in two aspects including yields and technical efficiency of crops. Findings The empirical results show that the overall climate appears a warming trend. Different from farmers in some other countries, Chinese farmers tend to adopt a more specialised cropping strategy which can significantly improve the technical efficiency and yields of crops in agriculture. In addition, as a moderating role, the specialised cropping can help farmers to alleviate the negative impact of climate change on technical efficiency of their crops. Originality/value First, previous studies showed that the changing climate influenced farmers' adaptation strategies, while most studies focussed on multiple adaptation strategies from the farm-level perspective rather than cropping strategy from the nation-level perspective. Second, the present study investigates how the cropping strategy affects the economic performance (in terms of the technical efficiency and crop yields) of agricultural production. Third, the stochastic frontier analysis method is used to estimate the technical efficiency. Fourth, this study explores the moderating effect between farmers' cropping strategy and technical efficiency by introducing an interaction item of SDI and accumulated temperature.

Tujuan dari penelitian ini adalah menganalisis strategi adaptasi komunitas nelayan terhadap dampak perubahan iklim. Lokasi penelitian di desa nelayan Asilulu, ditetapkan secara purposive mewakili karakteristik desa pesisir di kawasan pantai utara pulau Ambon Maluku. Metode yang digunakan adalah metode kasus historis sebuah metode studi sosiologi yang memadukan dua pendekatan yaitu sosiologi sejarah dan sejarah sosiologis. Pengumpulan data dilakukan dengan metode hermeunetik dan dialektika dalam waktu kurang lebih 2 tahun (April 2010 Juni 2012) menggunakan teknik pengamatan berperan serta, focus group discussion, wawancara mendalam, dan studi pustaka. Penelitian menunjukkan hasil bahwa komunitas nelayan di desa Asilulu telah merasakan dampak dari perubahan iklim yang menekan sistem penghidupan mereka meliputi kenaikan permukaan laut, intensitas badai dan gelombang tinggi, perubahan fishing ground dan kekacauan musim tangkap. Kerentanan komunitas dikategorikan tingkat sedang dan karenanya masih dalam area coping range komunitas. Nelayan melakukan adaptasi proaktif dan reaktif dalam strategi adaptasi fisik, sosial-ekonomi, dan sumber daya manusia yang sejauh ini mampu meningkatkan lebar selang toleransi sehingga kerentanan dapat dikurangi dan resiliensi sistem meningkat. Kondisi ini membuat komunitas nelayan cukup resilien.The purpose of this study is to identify the adaptation strategies of a fishing community to respond the impact of climate change. Location of the study in the fishing village Asilulu, determined purposively to represent the characteristics of the coastal villages in the north coast of the island of Ambon Maluku. The method used is the method of historical case a sociological study method that combines two approaches, historical sociology and sociological history. Data collected between April 2010-June 2012, using the technique of participant observation, focus group discussions, in-depth interviews, and literature. Research shows that the fishing community in the village Asilulu have felt the impact of climate change which suppress their livelihood systems include sea level rise, storm intensity and high waves, changes in fishing grounds and fishing seasons chaos. Community vulnerability and therefore categorized as being still in the area of community coping range. Fishermen proactive adaptation and reactive adaptation strategies in physical, socio-economic, and human resources are so far able to increase the width of the tolerance interval so that vulnerabilities can be reduced and the resilience of the system increases.
