Background of project Footer
Background of project The Nobel Prize-winning 2007 Intergovernmental Panel on Climate Change (IPCC) Report identifies Southeast Asia as among the most vulnerable regions on Earth. This is due in part to the geography of Vietnam as a low-lying coastal nation, the absolute number of people living in vulnerable, low elevation coastal zones (LECZ), defined as the contiguous area along the coast that is less than 10 m above sea level
Background of project Vietnamese researchers predict that a sea- level rise of 100 cm would cause a predicted land loss of km or 21.1 % of the Mekong River Delta’s land mass. This level of loss would expose and/or displace 17.1 million people, which is 23.1% of the population. For instance: Dongthap province - A province in Vietnam is a region located in the end of Mekong river. This province has about 1.67 million population in the area 3283 km2, population density 507 people per km2.
Background of project Energy Fresh water Transport ation Economy Waste Electricity in 2011 around 1,240 GWh and more than 99% families get electricity connection, electric price is cents per MWh Fresh water is for 85% families in 2010, the price is around cents per m3 Solid waste is 3.7 million ton per year, from domestic waste around 2.3 million ton per year including manure, percentage of organic waste is around 59% and recycle waste is only 13%, the treatment cost for each family is about 50 cents per month.
Background of project Footer Raining season: from May to November Drying season: from Dec to Apr 39000m3/sec in raining season. In the flood case, the water level can reach 4 meters above sea level Advantage: recharge ground water, making soil more fertile and provide nutrients, ect. Disadvantage: physical damages, water supplies, diseases, transport, economic, ect.
Background of project Sustainability development suggestion: 1.Energy: hydropower based, biogas 2.Water: raining storage, disinfection 3.Agriculture – Food: new technology 4.Health: improve sanitation system 5.Education: SD awareness, flooding risk management 6.Transport: boats, bridges, flood surviving kits, swimming training 7.Information: new development 8.Economy: fishing, new development 9.Architecture: new structures 10.Waste – The scope of project! The solid waste management problems to this province are lack of facilities to collection system, old and ineffective landfill plants, difficulties in the wet season whenever flood occurs
Project development Footer From Ark’s Project ‘One’ of Linda Beamish – Eco-Ark Design Consultant with solutions for an organic & ethical farm in a high risk flood zone.
Project development Footer Smart Waste Snorkeler (SWS) System was proposed for underwater waste management after the grand flood in 2031
Project development Footer Floating Architectural Structures Ideas
Project development Footer Landfill technology basis and toward to the floating or water –based treatment to organic waste
Project development Utilize barge structures Consider modified container structure Waste storage and closed treatment
Project development Project achievement: improve awareness of population to segregate solid waste by put different kind of containers for organic waste, recycle waste and hazardous waste. Consider using the recycled material bags made from coconut cover or grass, leaves. Proposal solid waste treatment on water –based: -Should have a floating supporting structure and enough strong in flood case -Leakage prevention systems -Closed system and can fermentation organic waste to produce biogas for energy usage -Easy to put waste inside and automatic closed Fixed volume
Project development Supply chain: -Suppliers: containers, barges, waste bags, transportation, supporting structures -Customers: residential area for around 20” volume of solid waste Saving current solid waste treatment costs Investment cost for one unit: -Barge cost: >30,00EUR (200ton) -Container cost: 1500EUR -Other cost Employment: Create new production – waste bags from biodegradable materials at local Employees for operating and collecting of this system
Project development Education: solid waste segregation to each family, sustainability development, health effects from untreated solid waste in the flood case, living with the flood training Networks: budget investment to purchase and install the system, subsidies to bags production, fines to families not collection and separate waste, sell biogas for users Scaling of projects: can apply for Mekong Delta regions Technology development: Government or NGOs support the budget on technology development of solid waste treatment methodologies on water- based.
Limitation of project 1.Time limitation and resources to design or study new technology for waste treatment 2.Geography limitation and experiments or data collection 3.Not consider recycle waste or hazardous waste 4.Not calculate exact the number of population, just assume Mekong delta region, and solid waste volume or timing of treatment 5.Not define exact place to place the project in the residential area 6.Need more studies how to link to sustainability development like creating biogas for energy at least during the flood season or fertilizers for agriculture from the project 7.Not discuss to industrial waste
Conclusion 1.Raise the new technology of solid waste treatment based on the flood case to open the problem of technology solutions in case it can not be applied landfill or incineration Footer
Project work The aim: −To tackle a sustainability challenge in a developing country setting and provide solution(s) that could be realistically executed. −Research a variety of options, and judge them by the criteria of sustainability, viability and possibility to scale the process up. −Reflect the complexity of sustainability challenges. −Identify and analyse the limitations of the project work
−The area and its inhabitants generally lack of general infrastructures, products and services. −energy: lighting with kerosene lamps, cooking with conventional coal/wood stoves. −water and sanitation: water available from collection points, water shortages and contamination common. Overpumping threatening the water sources. No official sewage treatment. −waste: no waste segregation, waste goes to a landfill with a truck. −food: markets are limited, served by small scale farmers and international companies. Access to global markets relies on multinational companies. Local farmers suffer from lack of resources and impacts of climate change (droughts, floods).
Assignment 1.Develop alternative lighting and cooking solutions (or a holistic electricity system). 2.Provide clean drinking water and sanitation services for the village/suburb. -Technology approach -Service approach 3.Develop a solid waste management system. 4.Develop a system that will enchange agriculture production and access-to- markets. 1.Technology/system approach 2.Wider market approach Remember, you don´t have to solve the entire problem, but the impact should be significant and realistic.
Assignment Areas needed to be thought/developed 1. Core problem you want to solve? (four themes) 2. The different stakeholders you have to/could involve a. the core stakeholders (technology providers, logistics, finance institutions, access-to-markets) b. auxiliary stakeholders (education?) 3. Economic aspect? −What is the value of this solution to different stakeholders? −How the money will circulate between the stakeholders? −Is a link missing? −Could this solution interest other stakeholders (bring value to them)? Or should we ask, how could this problem/solution interest other stakeholders? −How can the value of the ”product” upgraded? (turn it around, how can the value of the problem be discovered?)
Scope of the project work A) The core technology or processes What technology options or processes the group will investigate? −Sustainable in every aspect of sustainability? −Suitable for the local context? Should the technology or process be adapted? B) Economical feasibility Self-sustaining and able to create value for the different stakeholders. −What are the income earning possibilities (different stakeholders?) −Instead of resulting in heavy investing, subsidies and conventional “selling products”, the aim is to determine and develop innovative income earning possibilities. −The initial investment needs must be estimated and included the consideration of the project link to the technology solutions Footer
Scope of the project work c) Auxiliary processes/technologies −What auxiliary components are needed for the project to succeed? −Educational, awareness building mechanism? −Financing mechanisms? −ICT, social media, growdsourcing ? d) Networks What different stakeholders are involved? Who are in the core roles and who auxiliary? −Local groups? Companies?NGOs?( Micro)finance institutions? Governance bodies? Community based organisations? e) Scaling up the project Can the project be scaled to another location, to 1 billion people? Does it need adaptation? The five different aspects are reflected through ideas and suggestions of concrete execution, not just theory. Footer
−i.e. the field and the solution, the business model, stakeholder networks, auxiliary components − The area you base your project. −- The technology consideration. What technology (technologies) you chose? How these could provide added value to the area and its inhabitants? −- The supporting tools and components that are needed for this project to be successful (ICT, logistics, education). −- The monetary consideration. What sort of earning logic could you promote with the technology (and the supporting components) in question. (Who are the customers, who are the ones providing a service..) −For instance from the scope of the project slide, the points you should have figured out are A (The core technology or processes), B (Economical feasibility), C (Auxiliary processes/technologies) (à B&C leads to point D: networks). − Footer
−1. Where you set your project. This is the starting point for your iteration. Are you thinking of waste management, energy, sanitation etc or maybe a combination of few of these. It might be easier not to start with one technological solution, rather seeing it from the need point of view (such as need of healthy living conditions (waste management), need of energy, need of food and water). 2. IMPORTANT: where does the money come from? I find it useful to think the money flows through in a practical village setting (system approach). Who are the stakeholders, how can you add value to them? Which are the interlinking connections between the different stakeholders? You can use a value chain approach, but do not be to conventional (a to b connections do not work) instead try to see who and how a member of the chain can provide a service to another one. 3. How would you execute this project in practise. Who do you need (NGOs, firms, micro financing)? How is the project managed? The members of the system you are creating need to have both motivation and means (=resources) in order to continue the project. Two most important questions throughout the project are Do I provide a solution to a real need of the system? (or how can I provide a solution to a need. This also applies to the monetary system of your project.) Do I add value in every step of my project. Value is not equal just to money. Footer
