“…Furthermore, due to a lack of consumption data for irrigation water, we did not investigate this factor. In addition to increasing the use of physical inputs, R&D investment and institutional changes (e.g., the household contract responsibility system with remuneration linked to output) in China are also considered to be stimulating factors that improve the wheat yield [ 46 ], which should be investigated in a follow-up study.…”

“…Most of the previous studies have focused on investigating the impact of climate change on crop yields at the national level [ 44 , 46 ] or the regional level [ 37 ]. However, in China, the climate conditions, crop varieties and management patterns vary from each province.…”

“…Wang et al [ 56 ] investigated the effects of irrigation and nitrogen regimes on wheat growth and yields based on field experiments in Henan Province and found that the wheat yield was significantly impacted by irrigation and nitrogen fertilization. You et al [ 46 ] argued that using physical inputs could compensate for the negative effects of climate change on the wheat yield. Martín et al [ 57 ] modeled the impact of climate change on the wheat yield under different climate change scenarios using a calibrated version of AFRCWHEAT2 and found that agriculture management factors such as altering sowing the date and the nitrogen fertilization increased wheat yields.…”

Modeling the impacts of climate change and technical progress on the wheat yield in inland China: An autoregressive distributed lag approach

et al. 2017

This study aims to evaluate the impacts of climate change and technical progress on the wheat yield per unit area from 1970 to 2014 in Henan, the largest agricultural province in China, using an autoregressive distributed lag approach. The bounded F-test for cointegration among the model variables yielded evidence of a long-run relationship among climate change, technical progress, and the wheat yield per unit area. In the long run, agricultural machinery and fertilizer use both had significantly positive impacts on the per unit area wheat yield. A 1% increase in the aggregate quantity of fertilizer use increased the wheat yield by 0.19%. Additionally, a 1% increase in machine use increased the wheat yield by 0.21%. In contrast, precipitation during the wheat growth period (from emergence to maturity, consisting of the period from last October to June) led to a decrease in the wheat yield per unit area. In the short run, the coefficient of the aggregate quantity of fertilizer used was negative. Land size had a significantly positive impact on the per unit area wheat yield in the short run. There was no significant short-run or long-run impact of temperature on the wheat yield per unit area in Henan Province. The results of our analysis suggest that climate change had a weak impact on the wheat yield, while technical progress played an important role in increasing the wheat yield per unit area. The results of this study have implications for national and local agriculture policies under climate change. To design well-targeted agriculture adaptation policies for the future and to reduce the adverse effects of climate change on the wheat yield, climate change and technical progress factors should be considered simultaneously. In addition, adaptive measures associated with technical progress should be given more attention.

“…The variation in the pattern of rainfall has also affected more than one billion people in South Asia [3]. Researchers including [4][5][6][7][8][9][10][11][12][13][14][15] and many others have shown that climate change poses threats to agriculture, food and water supplies, especially in the developing economies. Most of the models indicate that climate variation would adversely affect the yield of wheat in South Asia.…”

Analysis of the Nexus of CO2 Emissions, Economic Growth, Land under Cereal Crops and Agriculture Value-Added in Pakistan Using an ARDL Approach

The present study attempts to explore the correlation between carbon dioxide emissions (CO2 e), gross domestic product (GDP), land under cereal crops (LCC) and agriculture value-added (AVA) in Pakistan. The study exploits time-series data from 1961 to 2014 and further applies descriptive statistical analysis, unit root test, Johansen co-integration test, autoregressive distributed lag (ARDL) model and pairwise Granger causality test. The study employes augmented Dickey–Fuller (ADF) and Phillips–Perron (PP) tests to check the stationarity of the variables. The results of the analysis reveal that there is both short- and long-run association between agricultural production, economic growth and carbon dioxide emissions in the country. The long-run results estimate that there is a positive and insignificant association between carbon dioxide emissions, land under cereal crops, and agriculture value-added. The results of the short-run analysis point out that there is a negative and statistically insignificant association between carbon dioxide emissions and gross domestic product. It is very important for the Government of Pakistan’s policymakers to build up agricultural policies, strategies and planning in order to reduce carbon dioxide emissions. Consequently, the country should promote environmentally friendly agricultural practices in order to strengthen its efforts to achieve sustainable agriculture.

“…The climatic intensity effect is determined by rainfall levels, patterns of temperature, the natural tolerance parameters for crops, the income per capita, the economic activities fraction those related to agriculture and pattern of employing of existing land (Benhin, 2006).

In South Asia, production of cereal crops is already under heat stress.…”

Efforts to sustain the global food system are suffering from the serious challenge of agricultural vulnerability to climate change. The current study is aimed at exploring the relation among yields of major food crops (wheat, rice and maize), climate change (temperature and rainfall), and technical progress (fertilizer and agricultural machinery) in Pakistan. In this regard, Autoregressive Distributed Lag (ARDL) model is employed using time series data over a period to time 1989 to 2015. To determine the co-integration, bound F-test results validate equilibrium for a long-run and short-run between yields of major food crops, temperature, rainfall, fertilizer and agricultural machinery. The long-run estimates indicate that area and temperature have a significant yet found a negative impact on wheat yield. However, for wheat yield, the coefficient of fertilizer usage was positive and had a significant effect. For rice crop, the coefficient of rainfall was found negative and had a statistically significant effect. The study concludes that climatic factors have a moderately negative impact on the yields of major food crops. The technical instruments and machinery needed to be enhanced since it plays an important role in increasing the yields of the crops. To deal and mitigate the negative effects of climate change, the government needs to develop agricultural adaptation policies, improve irrigation facilities and introduce high yielding and disease-resistant varieties for these food crops to ensure food security in the country.
