Opportunities and challenges for mangrove management in Vietnam


Book Description

In Vietnam, mangrove forests have been threatened by economic pressures and climate change. This report aims to analyze both opportunities and constraints for mangrove protection and management in Vietnam.The study found that local people appreciate the role that mangroves play in providing income, an attractive landscape and shelter from climate change related floods and storms. Many communities would be willing to contribute between USD 2-20 per year to a trust fund so as to protect their forests. A large number of policies and projects promote mangrove conservation activities. This has helped strengthen law enforcement, raised local awareness of the role and importance of maintaining forests, and restricted the conversion of mangroves to other economic activities. Government policies and development projects also provide capacity building, training and seedlings for mangrove reforestation activities at the studied sites. Additionally, new incentives such as payment for forest environmental services (PFES) are emerging as a potential source of finance to support mangrove protection and development in the future. Collective action for mangrove protection is widely recognized and promoted among study sites. People have self-organized strikes and protests to oppose converting mangroves to other economic purposes.Many policies and projects offer social and economic incentives for mangrove protection. However, they are impeded by insecure tenure, land grabbing, elite capture, inequitable benefit-sharing, and unclear responsibilities among government agencies at central, provincial and multilateral levels. Access to information on both policies and projects is difficult for local people. The monitoring and evaluation systems, incentives and disincentives designed by policies and projects have low enforcement and compliance. Policies and projects strongly emphasize and create incentives to replant mangrove forests, rather than to maintain and conserve existing mangrove forest areas. Incentives are also designed to compensate local labor costs for replanting mangrove or patrolling activities, rather than addressing the direct drivers of deforestation and degradation.Protecting mangroves requires a policy shift in land-use planning to address the drivers of mangrove deforestation and degradation. These drivers, in turn, respond to national and provincial economic development agendas, which focus on aquaculture expansion and migration. Cross-sectoral coordination also needs to be further enhanced to improve effectiveness in law enforcement. Enhancing local participation in mangrove forest protection and development requires a gender-sensitive approach and enabling conditions, such as well-enforced policies, accountable and transparent benefit-sharing, and inclusive decision making.




Competing for Land, Mangroves and Marine Resources in Coastal Vietnam


Book Description

This book presents a historical and ethnographic study of changing mangrove management in northern Vietnam over the past 100 years, grounded in a case study in the Red River Delta in northern Vietnam. The book shows that three primary socio-economic dynamics have affected mangroves: enclosure movements that have restricted access by different user communities over time, such as the exclusion of women; changing valuation of mangroves and their products and services; and social and class differentiation caused by privatization of once common resources. The result of these pressures have been erosions of norms, rules, and collective action to protect and nurture mangroves, leading to widespread loss of coastal forests. Sustainable mangrove management will require attention to these dynamics to address current-day land conflicts. The book will be of interest to policy-makers, practitioners, and academics and students in forest policy, management and governance; rural livelihoods; and globalization and agrarian change.




Methodology for assessing the role of mangroves in trace metal(loid) filtration to develop a mechanism of payments for environmental services for mangroves in Vietnam


Book Description

This document aims to provide an understanding of the scientific methodology that can be employed to demonstrate, monitor and assess mangrove-relevant environmental services by using case studies of mangroves in Hai Phong City and the Can Gio district of Ho Chi Minh City in Vietnam. In addition to previous work, this methodology evaluates the water purification services of mangroves in the context of existing policies on payment for forest environmental services in Vietnam, and discusses lessons learned, and funding requirements for effective assessment, evaluation and monitoring of the service. The findings contribute to identifying users and buyers of mangrove environmental services and developing implementation and monitoring mechanisms for payment for forest environmental services (PFES) through the application of environmental indices. The document is made in the hope that future studies can apply its methodology in other regions of the country to develop a database for evaluating the roles of mangroves throughout Vietnam.







Who will buy? Potential buyers for mangrove environmental services in Vietnam


Book Description

Key messagesWhen it comes to mangroves in Vietnam, the payment mechanism for forest environmental services (PFES) can be applied to 8 types of environmental services: (1) carbon absorption and storage; (2) sedimentation and sludge reduction; (3) coastal erosion protection; (4) wave shielding; (5) supplying clean water, filtering heavy metals and pollutants; (6) spawning grounds provision; (7) landscape – tourism; and (8) food and ingredient provision.There are 20 potential buyer groups that could pay for mangrove environment services in Hai Phong. These include: companies focused on dredging, sand mining, clean water, energy, banking, petroleum, entertainment, tourism, shipbuilding, air transport, and producers of agricultural, forestry and aquatic products; fishing and sea ports; those involved in the coastal economic zone; industries focused on mining and metallurgy, transportation and thermal power; dike management groups; and residential communities. While some buyer groups have expressed strong commitment to make payments (e.g. banks, energy companies, those producing agricultural, forestry and aquatic products), more research is needed to understand how willing other parties are to participate in paying for environmental services.In Hai Phong, two of these environmental services – (1) carbon absorption and storage and (5) clean water provision and heavy metal filtration – have the largest number of potential buyers.To develop a mechanism for payment for environmental services, four key questions must be answered: (1) Which services are being paid for? (2) Who is paying? (3) How much is the payment? and (4) What is the revenue and expenditure mechanism? Answering these will need long-term, thorough research, particularly demonstrating stakeholders use of environmental services. Based on the pre-feasibility study in 2018–2019, this policy summary answers the first two questions. The last two will be answered in another policy brief, once the study is complete in 2020.




Effect of Hydrology on Mangrove Ecosystems


Book Description

The development and distribution of mangrove forests vary depending on both biotic and abiotic factors. Differences in structure and function of mangroves are reflected in differences in their environmental setting, including their hydrological regime. However, The influence of hydrology on the mangrove forests of Vietnam has received little scientific attention, therefore the purpose of this book was to determine the effects of hydrology on specific structural attributes and functional processes within the mangrove ecosystems of Can Gio district, HCM City in southeastern Vietnam. This research addressed on: What are the characteristics of the hydrological regime at the Can Gio mangrove forest? and How does the hydrological regime in the Can Gio mangrove forest affect soil properties, sedimentation, litter decomposition, primary production and species distribution.I owe a debt of gratitude to Dr. Irving A. Mendelssohn, my major professor at LSU, Who has extolled a substantial amount of energy to guide me to complete the research and I would like to thank the MHO-8 (NUFIC) program for providing the financial assistance




Funding the protection and development of mangrove forests at sub-national level


Book Description

Existing financial incentive mechanisms (FIMs) to protect and develop mangrove in Ben Tre, Tra Vinh and Ca Mau come from 6 primary sources: central state budget; provincial state budgets; national scheme on Payment for Forest Environmental Services; foreign projects; public-private partnerships; and the private sector. These FIMs have provided funding to incentivise forest owners and provincial government agencies for better mangrove protection and development. Nevertheless, accessing to these funding schemes is difficult for forest owners due to complex procedures, the requirement to have high-counterpart funding, and high initial investment costs to meet access criteria. Due to challenges to access FIMs, these existing incentives are not attractive enough for forest owners to change their behaviour toward better mangrove protection and development.




Where to Put the Mangroves


Book Description

The objective of the thesis is to assess the trade-offs between shrimp aquaculture production and the delivery of the nursery habitat function from mangrove forest in Vietnam. Trade-offs are analysed by mean of a spatially explicit bio-economic model.
