Climate change has been and is a hot issue around the globe, which countries are interested in promoting research. In Vietnam, climate change mitigation and environmental protection is always a prominent topic, identified by the Party and State as an important task.
Especially in recent years,
prolonged drought and lack of water for irrigation have seriously affected
coffee productivity in the Central Highlands, Vietnam. In order to find a
solution to the above situation, Dr. Nguyen Dinh Tien - Head of the Department
of Natural Resources and Real Estate Economics, Faculty of Development
Economics, VNU University of Economics and Business, and colleagues have
conducted researches related to the topic of efficient use of irrigated water
under prolonged drought conditions. In particular, there are 2 studies
published in prestigious international journals, including: "Improving the
efficiency of irrigation water use of Robusta coffee (Coffea míaphora) in Lam
Dong province, Vietnam" and "Technical efficiency of water use for
irrigation of Robusta coffee production in Dong Nai River basin (Vietnam): A
case study of Lam Dong province".
The article "Improving the
efficiency of irrigation water use of Robusta coffee (Coffea míaphora) in Lam
Dong province, Vietnam" (2021) was published in Sustainability - an
international, multidisciplinary, academic, peer-reviewed, open access journal
on human environmental, cultural, economic and social sustainability. It
provides an enhanced forum for research related to sustainability and
sustainable development, published Monthly online edition by MDPI Publisher.
The content of the study delves into
analyzing the efficiency of using water for irrigation for Robusta coffee in
Lam Dong province. The author uses the Cobb-Douglas production function to
determine the change in coffee yield with respect to the application of
irrigation water and other production factors, with data collected from 194
farmers, and the efficiency engineering (TE) and irrigation water use
efficiency (IWUE) were analyzed using a data envelope analysis (DEA) model. The
correlation of various factors with IWUE was determined using Tobit regression
model. The results from the Cobb-Douglas model show that the volume of
irrigation water, the amount of working capital, labor and production scale
significantly affect coffee yield. Indigenous people use irrigation water more
efficiently than farmers migrating from other localities. Tobit results
indicate that farmers' experience, education level, distance from farm to water
source, security of access to water, access to credit significantly influence
IWUE. New findings continue to suggest that mitigating water shortages in
coffee farms requires sub-regional and national policy support such as better
access to credit and extension services, create and manage household-level land
to improve agriculture through the application of appropriate technologies and
traditional knowledge.
At the Proceedings of the First
International Conference on Economics, Development and Sustainability (EDESUS
2019) entitled "Global Changes and Sustainable Development in Asian
Emerging Market Economies", the study "Technical efficiency of water
use for irrigation of Robusta coffee production in Dong Nai River basin
(Vietnam): A case study of Lam Dong province” by Dr. Nguyen Dinh Tien and
colleagues analyzed the efficiency of irrigation water for Robusta coffee in
Lam Dong province by using the Cobb-Douglas production function. Technical
efficiency (TE) and irrigation water use efficiency (IWUE) were analyzed using
a data envelope analysis (DEA) model. Cobb-Douglas results show that the volume
of irrigation water and the amount of working capital, labor and production
scale significantly affect coffee yield. The study recommends that preventing
and mitigating water shortages on coffee farms requires more than just support
from national policy (access to credit and extension services, training,
management, etc.). land) but also need to improve household efforts in
necessary farming activities.
The above two research papers have
pointed out the direct effects of climate change and drought on coffee farms in
Lam Dong province, Central Highlands, Vietnam. This is the basis for functional
agencies and local authorities to come up with solutions to deal with drought
and improve irrigation water sources, helping coffee farmers' lives to stabilize
and develop their businesses, economic.
