2. The Environmental Impact of Industrialization

  • 2-1. Overview of Vietnam's industrial growth

  • Vietnam has experienced rapid industrial growth, achieving an impressive annual growth rate of 14% in recent years. This trajectory coincides with the nation's broader economic reforms initiated during the Doi Moi period, which catalyzed a transition from a centrally planned economy to a more market-oriented approach. As a result, the number of industrial enterprises has surged, presently numbering around 3, 000, with a significant portion—approximately half—classified as heavy industry. However, this expansion has not come without considerable environmental costs.

  • The industrial boom has increased the demand for natural resources, leading to significant ecological degradation. Not only has there been a notable rise in the volume of industrial waste, but the quality of wastewater management has also deteriorated. Studies indicate that most industrial wastewater, particularly from heavy industries, is discharged improperly. This lack of adequate treatment poses serious threats to Vietnam's rivers and ecosystems. For example, pollution levels in the Ku Cing River have significantly increased due to mining activities, and similar issues are evident in the Hong River, heavily affected by waste from industrial zones.

  • The urbanization accompanying industrialization has further compounded environmental issues. In cities like Hanoi, where rapid development has resulted in more than 300 industrial enterprises, the strain on infrastructure is palpable. The city's outdated sewage and drainage systems, coupled with a notable influx of vehicles emitting toxic gases, are contributing to increasing air pollution and urban flooding. Heavy rainfall frequently overwhelms these systems, resulting in flooded streets and substantial public health risks.

  • 2-2. The issue of wastewater management

  • Wastewater management in Vietnam is critically undermined by rapid industrialization. The burgeoning industrial sector generates vast amounts of wastewater, much of which is released into the environment without adequate treatment. It is estimated that only a fraction of discharged wastewater meets the required environmental standards, leading to severe repercussions for water quality in rivers and other natural water bodies.

  • The failure to effectively manage wastewater not only compromises water availability for domestic and agricultural use but also disrupts aquatic ecosystems. Rivers such as the Hong and Ku Cing have been identified as severely polluted, resulting in the death of aquatic life and the degradation of biodiversity. These issues are exacerbated by the lack of adequate regulatory enforcement and public awareness surrounding the importance of proper wastewater disposal and treatment practices.

  • Furthermore, public institutions have struggled to keep pace with the growing industrial sector, as highlighted by the lack of infrastructure capable of handling the volume and toxicity of industrial waste. Many industrial facilities are equipped with outdated technologies that are incapable of treating wastewater effectively. Consequently, this negligence highlights an urgent need for investment in modern treatment facilities, alongside stricter enforcement of existing environmental laws.

  • 2-3. Pollution of water sources and its repercussions

  • The pollution of water sources in Vietnam stands as one of the most pressing environmental issues resultant from industrialization. Rivers and lakes, once vital for agriculture, drinking water, and biodiversity, are now heavily contaminated due to industrial discharge and inadequate sewage treatment. This situation poses significant health risks to local communities that rely on these water sources for their daily needs.

  • For instance, communities near the polluted Hong River have been reported to suffer from various health problems, including gastrointestinal diseases, skin conditions, and other waterborne illnesses. The degraded water quality adversely affects not only human health but also agricultural practices, as contaminated water is often used for irrigation. This leads to food safety concerns, compounded by the bioaccumulation of harmful substances in crops cultivated using polluted water.

  • The repercussions of water pollution extend beyond immediate health issues; they also threaten to derail socio-economic development in affected regions. For example, fishing communities face declining fish stocks as aquatic ecosystems collapse under the pressure of toxic waste. This degradation leads to loss of livelihoods and increases poverty levels among populations already struggling economically. To mitigate these challenges, comprehensive policies addressing pollution sources and investment in cleaner technologies are critical for restoring water quality and protecting public health.

3. Assessing Climate Change Impacts in Vietnam

  • 3-1. Key climate change indicators: temperature rise and sea level increase

  • Vietnam is experiencing significant climate change, exemplified by rising average temperatures and increasing sea levels. Observational data indicate a notable warming trend, with average annual temperatures rising by approximately 0.24 °C to 0.28 °C per decade in coastal areas, particularly at Vung Tau and Ca Mau stations. This trend reflects a broader pattern of climate warming, with various regions of Vietnam observing significant temperature increases and altered precipitation patterns over the past five decades. Specifically, the northern coastal regions have reported an increase in maximum temperatures, while minimum temperatures have risen even faster, underscoring the complexity of climate dynamics within the country. Moreover, sea level rise poses a serious threat to Vietnam’s extensive coastal areas. Data from monitoring stations indicate an average sea level rise of about 2.8 mm per year from 1993 to 2008. Projections suggest that a one-meter rise in sea level could inundate approximately 11% of the population and 7% of agricultural land. This scenario would drastically impact densely populated and economically vital regions, particularly the Mekong Delta, where significant portions of land could be lost to rising seas, exacerbating challenges related to salinity intrusion and flooding.

  • 3-2. Consequences on socio-economic development

  • The implications of climate change on Vietnam's socio-economic development are profound. Due to its geographical vulnerability, the country faces increased natural disasters, including floods, droughts, and more intense storms, all of which disrupt daily life and economic activities. The National Steering Committee for Natural Disaster Prevention and Control reported nearly 1, 964 incidents of various natural disasters in the previous year, inflicting severe damage on infrastructure and human lives. With over 70% of the population residing in coastal zones and low-lying deltas, the socio-economic fabric of Vietnam is under threat from rising sea levels and extreme weather events. Economic studies predict a potential contraction of Vietnam's GDP by up to 10% due to climate change impacts. Agriculture, a cornerstone of the Vietnamese economy, is particularly susceptible. It contributes nearly 25% of GDP and sustains the livelihoods of around 60% of the population. However, with adverse climate conditions expected to lead to yield reductions ranging from 12% to 24% in staple crops like rice, food security and agricultural productivity are at risk. The ongoing transformation of land due to climate stressors is likely to displace agricultural communities, creating additional socio-economic challenges and driving urban migration.

  • 3-3. Government response and environmental policies

  • In recognition of the looming threats posed by climate change, the Vietnamese government has instituted a series of proactive measures aimed at mitigating impacts and enhancing resilience. Following recommendations from the National Party Congress, protecting the environment and adapting to climate change has been positioned as a priority within national policy.

4. The Role of Irrigation in Vietnam’s Agriculture

  • 4-1. Current state of irrigation practices

  • Irrigation plays a crucial role in Vietnam's agricultural landscape, particularly in the context of its status as one of the largest rice exporters since the late 1980s. Although Vietnam experiences high annual rainfall, averaging around 1940 mm, the distribution of this precipitation is uneven both temporally and spatially. This reality necessitates widespread irrigation practices to bridge the gaps where natural rainfall falls short. As a result, irrigated agriculture has become the largest water user in the nation. Over the past four decades, there has been significant investment in irrigation infrastructure, amounting to approximately 125 trillion VND, which has led to the establishment of around 100 large to medium-scale hydraulic works and over 8, 000 various irrigation systems, including reservoirs, weirs, and drainage gates. This infrastructure primarily supports paddy field irrigation, which is predominant in the Mekong Delta and coastal regions of Vietnam.

  • Management of irrigation resources is primarily state-dominated. However, recent reforms have initiated a shift towards more participatory approaches, including the establishment of water user associations (WUAs) and the promotion of participatory irrigation management (PIM) in several provinces. These evolving management strategies reflect a broader trend towards integrated water resources management, aimed at maximizing agricultural productivity while also addressing environmental concerns. Despite these advancements, challenges such as outdated systems, inadequate maintenance, and the reliance on heavy chemical use in farming persist, highlighting the complexity of irrigation management and its environmental ramifications.

  • 4-2. Irrigation’s impact on environmental sustainability

  • The impact of irrigation on environmental sustainability in Vietnam is multifaceted and poses significant challenges that require careful assessment. While irrigation is essential for agricultural productivity, particularly in supporting the extensive cultivation of rice, it also contributes to various environmental issues. One major concern is the pollution of water resources, which has been exacerbated by the overuse of pesticides and fertilizers in irrigation practices. Many farmers, lacking proper training and equipment, apply these chemicals at rates significantly higher than recommended, resulting in water contamination and detrimental health impacts. The runoff from agricultural fields can lead to toxic pollution in local water bodies, further stressing Vietnam’s rivers and ecosystems.

  • Moreover, the infrastructure associated with irrigation systems often suffers from inefficiencies that lead to high levels of water loss—some systems operate at only 44% of their designed potential. This inefficiency not only wastes valuable water resources but also contributes to saline intrusion in coastal areas, particularly during dry seasons. The degradation of soils due to erosion and chemical deterioration is another significant consequence of current irrigation practices. Such environmental impacts necessitate an urgent reevaluation of irrigation strategies in Vietnam, promoting practices that enhance sustainability while maintaining agricultural productivity.

  • 4-3. Challenges related to water sources for irrigation

  • Vietnam's irrigation practices face substantial challenges, particularly regarding the sources of water used for irrigation. The country has a varied water availability profile, with an estimated annual total of 830-840 billion m3 of water; however, only about 37% of this water is generated on Vietnamese territory. The uneven distribution of water, both temporally and spatially, leads to significant regional disparities. For instance, northern regions might experience severe water shortages during the dry season, while the Mekong Delta is often faced with saline intrusion due to sea-level rise exacerbated by climate change.

  • Furthermore, the dependence on both surface water and groundwater sources presents additional complexities. While surface water is more abundant, it is also more susceptible to pollution from agricultural runoff and urban activities. Meanwhile, groundwater resources remain underutilized due to insufficient infrastructure and a lack of robust management practices. Overall, the challenges surrounding water sources for irrigation in Vietnam underscore the need for integrated management approaches that balance agricultural demands with sustainable water use, particularly in the face of changing climate conditions that are likely to intensify water scarcity issues.
