Erosion in the coastal areas of the Vietnamese Mekong Delta: Current challenges and solutions

Coastal erosion is one of the types of geological disasters that is occurring quite commonly and seriously in the Mekong Delta. The problem of landslides and erosions is one of the major concerns for coastal stability. Currently, along 9 coastal provinces, there are over 115 serious erosion and landslide points; each year, a total of 300 –500 hectares of coastal land can be lost. Erosion and landslides narrow the area of mangrove forests, residential land, and aquaculture land of local people. The Mekong Delta has to spend billions of VND yearly to build breakwaters and sea dikes and restore mangrove forests. Many structural and non-structural measures have been implemented to reduce the risk of erosion over the past two decades. However, there is not much assessment of the sustainability of landslide prevention projects. The research question is what are the challenges and difficulties in the ongoing fight against erosion in the coastal plain. Through a practical approach from surveying works in coastal areas, the results show that choosing an effective solution depends mainly on the cost factor and the terrain of the ground. Water resource management policy on the Mekong River system is difficult to find a satisfactory answer.

Applying GIS and Markov chain in establishing the land use change map and forecasting land use changes in Thach That district, Hanoi city

The study applied GIS and Markov chains to assess land use changes in the period 2015-2020 and forecast land use change trends in Thach That district, Hanoi city until 2030. Using two maps of the land use status quo map in 2015 and 2020 of Thach That district and 2 period land statistics, the research result has established a land use change map in Thach That district for the period 2015 - 2020 for 16 types of land with a land change rate of 9.63% of the total natural area. During this period, the land types that tend to increase are Perennial crop land; Special-use Forest land; Aquaculture land; Other agricultural land; Residential land; Special-use land; Land for religious establishments; Land for beliefs establishments and Specialized water surfaces with an increased rate of 0.05-2.28%. In contrast, land types with a decreasing trend are Annual crop land; Production Forest land; Protective Forest land; Cemetery land, cemetery, funeral home, crematorium; Land of rivers, streams, canals and streams; Other non-agricultural land, and Unused land which decreased at a rate of 0.02-2.34%. It is forecast that by 2030, agricultural land will have 10,271.28 hectares (accounting for 54.90%), non-agricultural land will have 8,432.22 hectares (accounting for 45.07%), unused land will have 4.76 hectares (accounting for 0.03%). Performing a T-Test (Paired two sample for Means) between the area from the forecast and the planned area until 2030 shows that ρ = 0.979 > 0.05. Thus, it proves that the results of forecasting land use changes to 2030 using the Markov chain compared to the land use planning plan of Thach That district do not have too big a difference. The results of assessing land use changes and making forecasts of land change trends in the Thach That district contribute to helping policymakers have an objective view of land-use planning and economic development sustainably.

Biochar for Improving Growth Performance of Shrimp and Environmental Quality in an Inland Saline Culture System.

The current study, which lasted 45 days, was designed to find a more effective way to use the vast resources of salt-affected land and ground saline water for aquaculture. Biochar made from agrowaste was used as a sediment amendment. The 100 g of biochar was applied to 25 kg of sediment (i.e., 9.0 ton ha-1) in 300L capacity fiber reinforced plastic, and Penaeus vannamei (P. vannamei) (2.74 ± 0.03 g) was stocked at 90 juveniles m-2 in inland ground saline water of salinity 10 ppt fortified with potassium levels that are 50% equivalent to those of seawater. Among different treatments, T1 indicates paddy straw biochar (PSB) application in sediment; T2 indicates sediment amended with KOH-activated PSB; T3 indicates sugar cane bagasse biochar (SBB) application in sediment; and T4 indicates sediment amended with KOH-activated SBB. Compared to the control the potassium (K+), alkalinity, total hardness, calcium/magnesium ratio, and pH of the water increased significantly (P ≤ 0.05) in treatments where biochar was used as an amendment in sediment. The T3 treatment had the best Ca/Mg ratio (1.00:3.12). In water, the magnitude of increase in K+ concentration from high to low followed the order: T2 > T4 > T1 > T3 > control. The concentration of NH4+-N in water was found to be increasing in control, whereas in the rest of the treatments, it decreased significantly from day 1, until the end of the experiment. Compared to control, the bulk density was decreased, and sediment cation exchange capacity and water holding capacity were increased significantly in treatments where biochar was used as an amendment. The soil microbial parameter measured in terms of soil enzyme dehydrogenase was significantly different among treatments at the end of the experiment. Weight gain (%), specific growth rate (SGR), survival (%), and feed conversion ratio of P. vannamei varied significantly in T1, T2, T3, and T4 compared to the control. The SGR (2.38b ± 0.05% day-1) and weight gain (%) in T2, and survival (96.1b ± 2.0%) in T3 treatment were found to be the highest at the end of the experiment. When biochar was mixed with sediment in the inland saline system, an improvement was seen in sediment quality, water quality, and growth characteristics of P. vannamei.

Assessing 30-Year Land Use and Land Cover Change and the Driving Forces in Qianjiang, China, Using Multitemporal Remote Sensing Images

Assessing Land Use and Land Cover Change (LULCC) related with aquaculture areas is vital for evaluating the impacts of aquaculture ponds on the environment and developing a sustainable aquaculture production system. Most studies analyze changes in aquaculture land in coastal areas, and little research focuses on the inland area, where the conversions between agriculture and aquaculture land is primarily driven by socioeconomic factors. This study assessed LULCC related to aquaculture areas in Qianjiang City, China, from 1990 to 2022, using multitemporal Landsat images and a combination of decision tree classifier and visual interpretation. The LULCC was analyzed by the transition matrix. Results showed that the main LULC type was farmland, which accounted for more than 70% of the study area from 1990 to 2022. The built-up and aquaculture land showed an increasing trend year by year. In contrast, there was a gradual decline in forest/grass land from 1990 to 2016, and then its area increased slightly from 2016 to 2022 due to the policy of returning farmland to forest. Water areas were mainly composed of rivers and ponds, with subtle changes during the study period. The main driving forces of LULCC in Qianjiang City were economic and policy factors, with rapid GDP growth and government policies being the dominant factors.

A quantitative analysis of the impact of reclamation on the stability of coastal wetlands

The ecological stability of coastal areas is seriously affected by tidal flat reclamation. Understanding the spatial characteristics of the impact of reclamation on stability, as well as the contribution of different use types of reclamation to stability change, is important for mitigating the negative effects of reclamation. In this study, multi-source and multi-temporal remote sensing images were combined to quantitatively analyze the relationship between reclamation and stability in different regions of the coastal area in Jiangsu Province, as well as the relative contribution of different use types of reclamation to the stability change. The results showed that: Different forms of statistical relationships between reclamation and stability existed in reclaimed area and non-reclaimed area, respectively, while a significant quadratic function relationship existed in the whole affected area, and the stability index decreased first and then increased with the increase of reclamation amount, with a threshold of 1243 km2; In different buffer zones within the non-reclaimed area, the impact intensity of reclamation showed spatial decay characteristics; The use type of reclamation that has the greatest impact on stability in the reclaimed area is aquaculture land, while in the non-reclaimed area it is arable land. In addition, aquaculture land, arable land and hydraulic engineering land have negative effects on stability, while salt industry land has positive effects.

Distribution, sources, and ecological risk assessment of polychlorinated biphenyls (PCBs) in the estuary of Dagu River, China

Four different types of 0–30 cm soil/sediment samples were collected from aquaculture land, farmland, industrial land and river bottom sediment in the estuary area of Dagu River, and the pollution status and sources of 7 PCB congeners were analyzed. The results showed that the mean values of Σ7PCBs in soil/sediments of different land use types were 5.01 ng g−1 dw for industrial land, 3.6 ng g−1 dw for estuarine sediments, 2.09 ng g−1 dw for farmland soil and 1.78 ng g−1 dw for farming land. All samples were at low pollution levels and pose little ecological risks. PCBs in the samples are mainly comprised of highly chlorinated biphenyls, and their content decreases gradually with increasing sampling depth. Based on the principal component analysis, it is concluded that the main source of PCBs in the study area is shipping activities, in addition to atmospheric transport and sedimentation sources.

The article presents the analytical description of the current situation of aquaculture development in Samtskhe-Javakheti region and in Georgia in general. The data about sector development natural potential are provided, the indicators of the fish production dynamics are analyzed in the paper. Water resources have a great potential and their ecological-sound use enables Georgia to meet not only an internal demand of the country on the fresh water fish, but also due to specifics of the local waters, produce export product. Internal water resource of fresh water for fishery production includes total water surface of 16,900 ha of 860 lakes. Samtskhe-Javakheti region is distinguished with the specific water resources compared to other regions. The regions is rich with the hydro-resources, including the R. Mtkvari water-collecting basin, the basin of the rivers Uraveli, Paravani, Borjomistskali and Gujaretistskali with total size 6,250 m2, with the total water resource of 3, 475 mln m3. The region territory covers 15 non-drying, 25 drying and 64 little lakes, 5 water reservoirs transforming into the swamp of the hydro-resource objects. The total size of the basin of the main lake exceeds 983 m2, the volume of the water reaches to 400 million m3. The water reservoir located in the Lirbalakhi basin in the region includes 2.08 million m3, and the size of the swamps is 817 ha in the region. The article studies the dynamics of the land plots occupied by aquaculture. According to the data, there is 23% of growth of the land plots occupied by aquaculture in entire Georgia; while the situation is different in the target region, there is 10% of reduction, followed by reduction of the share of aquaculture land from 11.1% until 10.6%. Study of the aquaculture fodder supply demonstrated that use of combined fodder is increasing in Georgia; average rate of the growth consists of 5-7 % in the country, while the rate is higher in Samtskhe-Javakheti region, where use of combined fodder achieved 35% of growth. There is tendency of growth in use of all kind of fodder. The index of the fodder expenses reached 1.30 throughout entire country, while it is 1.38 in Samtskhe-Javakheti, indicating strengthening of the fodder basis and intensive development of the field. The analysis of fish production dynamics is also an indicator for the further development of the aquaculture. In 2021 compared to 2019, there is 16% of growth in production of the fish, comprising 2,861 tons. The growth achieved 24% in the same period in the region what can be considered as a positive phenomenon in fishery production in Georgia, where the share of the fish farms (family-run) was increased up to 60% with growing engagement of the farmers aged 25-45 from 20% up to 29%. The rate of fish production is in compliance with the increased rate of water stock. The study revealed the specific problems (fish structure, diversification of the fodder, veterinarian service, growing of young fish) requiring solution to increase development of fresh water fish breeding, making financial sustainability of farming and economic growth of the region.

Are Aquavoltaics Investable? A Framework for Economic and Environmental Cost-Benefit Analysis

Aquaculture has long been a significant industry in Taiwan, contributing significantly to the country’s GDP through both exports and domestic consumption. However, certain aquaculture practices have faced criticism due to their heavy groundwater usage, resulting in environmental damage such as land subsidence in the southwestern region of Taiwan. In order to change the industry’s negative environmental image and achieve the ambitious targets set by the Taiwanese government, including 20 GW of solar photovoltaic power by 2025 and net-zero carbon emissions by 2050, the utilization of aquaculture lands, particularly aquaculture ponds, has emerged as a promising option for solar power development. As the government promotes the symbiosis of aquaculture and solar PV power to attain its renewable energy goals, various stakeholders have engaged in discussions surrounding this approach. Consequently, it is crucial to assess the costs and benefits of such integrated practices from both economic and environmental perspectives, as it will play a pivotal role in shaping the future of the industry. A comparative analysis reveals that an aquaculture–electricity symbiosis with a capacity of 227 MW can further reduce carbon emissions by approximately 150,393.6 tons of CO2e per year, along with reductions of 56.8 tons/year of SOx, 82.3 tons/year of NOx, 3.7 tons/year of PM2.5, and 4.6 tons/year of PM10. These environmental benefits are equivalent to approximately TWD 7626.43 million annually. (Note: CO2e refers to carbon dioxide equivalent, SOx refers to sulfur oxides, NOx refers to nitrogen oxides, PM2.5 refers to fine particulate matter, and PM10 refers to particulate matter with a diameter of 10 μm or less).

Aquaculture, household income and inequality in Vietnam’s coastal region

Using data from the 2020 Vietnam Household Living Standards Survey, we examine the link between aquaculture, household income, and inequality in Vietnam’s coastal region. Using a two-step cluster analysis, we identify five clusters of livelihood strategies (LS) pursued by local households. We find that about 13% of the total number of households are engaged in aquaculture, but only 6% pursued an aquaculture LS, while half the number of households followed a wage-earning LS. Our regression analysis shows that, on average, those in the aquaculture LS cluster have higher incomes than those in the wage-earning or “other income” LS clusters. Interestingly, the quantile regression result reveals that in the top percentiles of income distribution, those adopting an aquaculture livelihood attain higher incomes than those in all other livelihood clusters. This implies that there is a positive link between the choice of aquaculture LS and household income. Also, we find that aquaculture land is positively associated with the likelihood of participation in aquaculture and deriving income from it. Notably, Gini decomposition analysis indicates that the distribution of aquaculture land and income from it are highly uneven and skew much more towards the well-off. Given the significant positive relationship between aquaculture land and the profitability of the aquaculture LS, our findings imply that expanding the aquaculture sector (e.g., granting access to aquaculture land or/and training in skills for aquaculture farmers) may help local households boost their income and reduce inequality in the coastal region.

Implementation of Artificial Intelligence in Aquaculture and Fisheries: Deep Learning, Machine Vision, Big Data, Internet of Things, Robots and Beyond

The aquaculture and fishery industry are multi-billion-dollar business across the globe, and the demand for aquatic species produce increases exponentially throughout these years. However, the depletion of aquaculture lands and aquatic pollution are some of the major worrying predicaments challenging the future of this industry. Sustainable growth strategies are the only way out, and they must come hand in hand with the implementation of artificial intelligence to achieve the desired outcome high throughput in short time periods. The intelligent fish farm and smart cage aquaculture management system are some of the fruits of this drive, and the system keeps improving to date. In this review, we provide recent updates over the past half-decade of artificial intelligence implementation in fishery and aquaculture in hope to provide highlights and future directions to push the industry to greater heights.

Agriculture and aquaculture land-use change prediction in five central coastal provinces of Vietnam using ANN, SVR, and SARIMA models

Abstract Vietnam’s economy with agriculture and aquaculture still account for roughly 26% of the country’s gross domestic product, and nearly 70% of the Vietnamese population lives in rural areas; therefore, agriculture and aquaculture land use play a crucial role in the development process of Vietnam. Rapidly increasing population and infrastructure in rural areas and industrial zones lead to these land-use changes. Hence, these land-use change predictions are crucial for local authorities and the local people to make land-resource funds and set up planning. This article suggests support vector regression (SVR), artificial neural network (ANN), and seasonal autoregressive integrated moving average (SARIMA) methods to predict land-use change. By comparing the three models, the results indicate that almost all of the SVR models improve the accurate performance more than ANN and SARIMA in Quangtri, ThuThienHue, Danang, and Quảngnam provinces. Furthermore, the ANN model indicates more accurate forecasting than the SVR and SARIMA models in Quan Binh province. The result may be support for the Ministry of Natural Resources and Environment to conduct the land-use inventory and upgrade agriculture and aquaculture land-use change maps every 5 years. Afterward, the Department of Natural Resources and Environment’s provinces use the estimating database and update it manually.

Managerial Pattern and Work Relations at Traditional Pond in Pangkajene and the Island District (Milkfish Aquaculture Case in Bonto Manai Village)

Improving the quality of traditional farmers on a technical, social and economic scale, is strongly influenced and determined by the capacity to carry out pond business activities related to managerial patterns and work relationships that are formed. This research was conducted in October – December 2021. Milkfish (Chanos-chanos) aquaculture business in Bonto Manai Village was chosen as the case, because the aquaculture system managed by the community is dominated the traditional aquaculture system. The purpose of this research is to analyze the knowledge of traditional aquaculture as a technical practice in managing aquaculture businesses, as well as to analyze the work relations of traditional aquaculture businesses which are internalized in the local culture of the community. The methodology used is a case research method with a descriptive qualitative data analysis approach described in the life history of the informants. The results showed that traditional farmers in milkfish (Chanos-chanos) aquaculture in Bonto Manai Village have acquired knowledge gained through experience passed down from generation to generation, starting from the construction and management of pond subgrade, seed stocking, rearing, harvest and post-harvest. Accompanied by rituals based on belief as a traditional value. The managerial pattern and work relations in the management of traditional pond business have three types of management, namely; aquaculture business which is self managed by the owner of the aquaculture land with involving two to three workers, aquaculture business which is managed based on a leasing system, and aquaculture business which is managed by a rapture system. Keywords: Managerial Pattern, Work Relations, Traditional Pond, Milkfish

Integration of geospatial technologies with multi-criteria decision analysis for aquaculture land suitability evaluation: The case of Fincha'a River Sub-basin, Western Ethiopia

Assessment of physical land suitability for aquaculture is a prerequisite for promoting fish farming and enhancing food security as increase in global population and fish demand is tremendously rising. In addition, our country is also riches in enough water resources and conducive environments. Despite these facts, the vast majority of the local communities in Ethiopia are not benefited from aquaculture due to limited information and infrastructures. This study intended to assess land suitability for aquaculture using geospatial techniques in Fincha'a river sub basin, western Ethiopia. In the present study, slope, river, road, market, land use land cover (LULC), soil types, land surface temperature (LST), rainfall, lakes and reservoirs were performed using multi criteria Evaluation (MCE) based Pairwise Comparison Matrix to evaluate land suitability for aquaculture. The results revealed that, about 51.4km 2 is highly suitable, while 843.5km 2 categorized under moderately suitable. About 1483.5km 2 were categorized under marginally suitable, while 56.5km 2 is not suitable for aquaculture. Based on the result, we recommend that, community awareness is required to utilize maximum potential of aquaculture farming, that may contribute towards poverty eradication and food security in Ethiopia. • Warm area and wetland areas were highly suitable for fish farming. • Analytical hierarchy process is a powerful method to generate land suitability for aquaculture. • Land suitability assessment can indicate the potential of particular land for different purposes. • Utilizing maximum potential of aquaculture farming, that may contribute towards poverty eradication and food security in Ethiopia is forwarded.

Kinerja Produksi Ikan Sidat (Anguilla Bicolor Bicolor) dengan Volume Air Pemeliharaan yang Berbeda pada Sistem Resirkulasi

Eel (Anguilla bicolor bicolor) rearing activities that develop in Indonesia generally still use a large volume of water. The application of a recirculation system reduces water requirements and at a small volume of water, the load on the container to accommodate water becomes lighter so that several containers can be arranged vertically. This study aims to determine the best water volume in eel rearing with a recirculation system on production performance. This study used a completely randomized design with four treatments and three replications. The treatments, namely the difference in the volume of water (VA) used in the maintenance container, included VA 2.5 L (A), VA 3.5 L (B), VA 4.8 L (C) and VA 5.8 L (D). Eels were reared for 60 days in an aquaverticulture system with a stocking density of 10 fish per container. The test parameters in this study included survival rate (SR), specific growth rate (LPS), absolute weight growth (PBM) and feed conversion (FCR) and coefficient of final weight diversity (KKb). Other parameters analyzed include water and land use analysis. The results showed that aquaverticulture with multilevel containers on eel produced the best water volume of 5.8 L with high production performance (100% survival, specific growth rate 1.60%/day). The volume of water needed to produce 1 kg of eel for 1 year is 27.69 liters and the productivity of aquaculture land is 86.14 kg/m2. During the COVID-19 pandemic, this system design has been applied on a laboratory scale, but has not been applied commercially in the community.

STUDY ON POTENTIAL FEASIBILITY OF AQUACULTURE LAND USING GEOGRAPHIC INFORMATION SYSTEM (GIS) IN NORTH SEMARANG SEA

Marine culture in the North Semarang area is still not optimally utilized by the surrounding community. The selection of the location of aquaculture activities is needed to determine the feasibility of suitable land for aquaculture in the sea. However, due to the large number of fishing activities, ports, and dense settlements have an impact on water quality which affects marine aquaculture activities. The purpose of this study was to determine the condition of the waters, determine the level of land suitability using GIS, and the area of ​​land that can be used as a location for marine culture in the waters of North Semarang. The method used is by scoring and GIS. Parameters observed included protection, brightness, temperature, depth, current velocity, substrate, wave height, salinity, DO, BOD, COD, and pH. Furthermore, a scoring calculation is carried out to determine the suitability value which is then processed using GIS to produce a suitability map. The results showed that North Semarang waters were classified as S2 class (quite suitable) for marine aquaculture activities and with an area of ​​250,000 ha

Transformation and risk assessment of the East Kolkata Wetlands (India) using fuzzy MCDM method and geospatial technology

The East Kolkata Wetlands (EKW) is located on the eastern periphery of the city of Kolkata and extends up to the Bidyadhari-Matla River confluence. It is a Ramsar Site and acts as an absorber basin for a large number of contaminants drained from Kolkata. Agricultural lands, sewage-fed fisheries, garbage dumping fields, horticulture, and built-up areas are included in this protected area, that covers approximately 125 km2. It reveals that climate change reduces the variety of wetland ecosystem services and increases socio-economic vulnerability and economic stress. The human encroachment, reclamation of land for agriculture, aquaculture, and urban expansion in and around Kolkata has recently adversely threatened the EKW. The remotely sensed data, socio-economic data, and responses of inhabitants have been used to analyse the EKW’s risk and vulnerability. We employed geospatial analysis by using the Multi-Criteria Decision Making (MCDM) method using nine risk factors. An in-depth analysis of the EKW using geospatial techniques and the Fuzzy Analytic Hierarchy Process (FAHP) helped to understand the EKW transformations through vulnerability and risk analysis. The results show that the transformation of the wetland to aquaculture, eutrophication and pollution, road proximity, waste dumping, population density, and growth are the main factors for the deteriorating health, quality, and environment of the EKW. It also reveals that quantitative and qualitative evaluations of ecosystem services, wetland degradation, transformation, and cause-effect rapport should be periodically assessed using scientific methods like FAHP, RS, GIS to formulate resilient, integrated plans and strategy for the sustainable management of the EKW.

Land Use and Land Cover Change Detection in East Godavari District, India (2002-2020)

Land Use Land Cover (LULC) dynamics must be monitored and mapped because changes in land cover reflect the state of the ecosystem and provide a clear picture of optimal natural resource utilization. The goal of this study was to use Remote Sensing and Geographical Information System techniques to classify and map LULC in the study area. This research is divided into two sections: (1) LULC classification and (2) Accuracy assessment. Between the years 2002 and 2020, satellite remote sensing data was acquired from the United States Geological Survey and analyzed using Arc GIS 10.1 software. The study region was divided into six major LULC types: agricultural land, built up area, barren land, forest and sediment using the likelihood classified approach and quantifying the changes throughout the time period indicated. According to the findings, Settlement area increased from 1.22 % in 2002 to 10.8 % in 2020, barren land increased from 7.58 % to 12.96 % in the same period, agricultural area decreased from 21.83 % in 2002 to 18.53 % in 2020, and forest cover decreased from 8.9 % to 2% in the same period, according to the findings.
