suggested method by looking at five key commodities'
price histories: wheat, millet, sorghum, maize, and
rice. Developing nations that produce a major portion
of the world's these crops or are among the top
producers globally are the primary focus of the study,
along with the average production share worldwide.
From 2005 to 2017, we use training data. From 2018
to 2022, we test the model. From 2023 to 2030, we
predict the worldwide prices of key commodities. The
goal of making these forecasts is
to provide farmers and policymakers with more
information they can use to make informed decisions
that will help in the global struggle for food security.
In support of the viability of the economy and
agricultural development, there needs to be stability in
the agricultural futures market (Tingting Zhang, et
al.,2023). Due to the complexity of changes in
agricultural futures prices, it is not easy to overcome
the restrictions that the current data preprocessing
techniques put in place for improvement of the
models’ ability to forecast. In this study, we propose
a novel VMD-SGMD-LSTM model that combines
state-of-the-art quadratic decomposition with an AI
framework. First, we use VMD to clean up the raw
futures price data, and then we let SGMD deal with
the rest of the components. Secondly, several modal
components are predicted using the LSTM model, and
then the result is achieved using the predicted values
from the different components. In addition, using data
from the Chinese agricultural futures market for
wheat, maize, and sugar, this study offers empirical
analysis in one-step, two-step, and four-step forward
forecasting scenarios, respectively. By
outperforming other benchmarked models in terms of
predictive power and resilience across several
agricultural futures, the results show that the VMD-
SGMD-LSTM hybrid model suggested here
overcomes the constraints of earlier research.
Predicting agricultural prices accurately is critical
to achieving the agricultural sector's sustainable and
healthy development, making it a popular study issue
in the sector (Feihu Sun, et al.,2023). It delves into the
many ways of forecasting, including classic,
intelligent, and combination model approaches, and
discusses the difficulties that researchers have when
trying to estimate the prices of agricultural
commodities. The findings of the study propose the
following: (1) the ARIMA and exponential smoothing
price forecasting of agricultural products will be a
developing trend for the future, and understanding the
reasons for the combination will help improve
accurate forecasting; (2) future forecasting models
will continue to incorporate structured, unstructured
data, and variables; and (3) when forecasting these
agricultural product price estimates, accuracy of
values in addition to trend forecasting accuracy will be
advantageous. This manuscript serves to progress a
future durability research agenda, as it reviews and
analyses price forecasting agricultural product
methods.
Predicting agricultural commodity prices with any
degree of accuracy is difficult because of how
complicated and unpredictable these markets are
(Kapil Choudhary, et al., 2025). Predictions made
using current models are generally inaccurate because
they do not account for non-stationary and nonlinear
trends in pricing data. A new hybrid VMD-LSTM
model is introduced to address these challenges; it
combines genetic algorithm, variationally mode
decomposition and long short-term memory (LSTM)
to enhance prediction accuracy. The proposed model
uses GA-optimized VMD, a technique for breaking
down price series into intrinsic mode functions (IMFs)
with the desirable property of sparsity, to speed up the
convergence process. Next, model and forecast each
of these IMFs separately using LSTM models that
have been optimized using GA. The final step in
generating the actual price series is to combine the
predictions of all IMFs. The VMD-LSTM is put to the
test in comparison to three other LSTM and
decomposition-based models using monthly pricing
data for maize, palm oil, and soybean oil (EEMD-
LSTM, CEEMDAN-LSTM). It is possible to measure
the efficacy using directional prediction statistics, root
mean square error and mean absolute percentage
error. As compared to the next best CEEMDAN-
LSTM, VMD-LSTM decreases RMSE by 56.93%,
MAPE by 44%, and palm oil by 21.67% and soybean
oil by 25.85%, respectively. The improved prediction
accuracy of VMD-LSTM is further supported by
TOPSIS and the Diebold-Mariano test. Farmers,
dealers, and policymakers might all benefit from the
proposed model's improved agricultural price
predicting capabilities.
3 METHODOLOGY
The research on the topic of agricultural product price
forecasting is one that is all-encompassing,
interdisciplinary, and constantly evolving. Data
sources, data types, data quality, data processing
techniques, model design techniques, and model
evaluation techniques are always evolving, which
means that the methods used to predict the values of
agricultural goods will also be improved and updated.
The employment of combination optimization
methods by predictive models has been demonstrated
