Category: Urbanization & Household

Urbanization refers to the increasing population in urban areas, primarily large cities and metropolitan areas. Already more than half of the world’s population lives in urban areas and according to the United Nations it is predicted to increase to 64% and 86% in the developing and developed countries respectively by 2050. Modernization, industrialization and the associated impacts of rationalization are basic drivers of urbanization and didn’t happen overnight. Such evolution has interesting historical and cultural background. The accelerating urbanization has, however, diverse economic, environmental and social effects and thereby strong impacts on the process of achieving sustainable socio-economic developments around the world. In this context, landscape architecture, civil engineering and design are primary components for construction and development of large-scale living areas that can effectively integrate urban and rural areas. This evolution may involve diverse landmarks and structures to meet preset environmental, social-behavioral and aesthetic requirements both in terms of needs and standards. Systematic investigations and compilation of necessary social, ecological, and geological information including processes in the landscape and necessary interventions are of interest in this context. The scopes of profession include urban planning and design; environmental, social and cultural aspects (parks, recreation, storm and rain/snow/sand management); green infra-structures; trade and service centers; ….. . In addition to private estate and residence landscape, supplementary infrastructures should be in place to effectively couple urban and rural areas.

Lessons to be Learned – Most Polluted Air and Water on Earth

Among the most important indicators for life on earth are air and water qualities with poor qualities of air and water it becomes difficult, even impossible, to sustain life in any form. In some places in the world abuse of the natural resources, e.g. blind exploitation, production and use, have caused serious degradation and enormous damage, of natural environments. Exploitation, production and consumption are associated with environmental, ecological and human costs in form of “environmental, ecological and health degradation” and if such costs are not accounted for we will have negative sustainability balance. With gradual pile-up of such environmental, ecological and health debt, as is the case in the given examples, there would be no places on earth for suitable and sustainable life.

Is Your City Sustainable? Top Five Most Sustainable Cities in the World.

The following are currently considered to be the top five most sustainable cities in the world:  VANCOUVER, CANADA; SAN FRANCISCO, U.S.; OSLO, NORWAY; CURITIBA, BRAZIL; and COPENHAGEN, DENMARK.

When it comes to implementing sustainable initiatives these cities are leading the globe in how that achieved and/or can achieve sustainable cities through using renewable energy and by cutting back on emissions. Among common sustainability characteristics of these cities (http://archive.rec.org/REC/Programs/SustainableCities/Characteristics.html) are:

leadership in using and developing renewables; green transport and traffic with low emissions; strict and green buildings with improved energy efficiency and ongoing LEED-certified green building projects); high marks for air quality and clean environment; waste management with efficient and high recycling rates; reserve high percent of land to green spaces, ongoing projects for efficient electric car traffic (Vancouver and San Francisco); protected forest, parks waterways, and agriculture land (e.g. Oslo, Curitiba); intelligent lighting adjusting intensity depending on traffic conditions and weather (Oslo); bio-methane from waste to power mass transit and heating; projects for cutting carbon emissions by 50 percent in coming decades with goals to be the world’s first carbon neutral capital by 2025 (Copenhagen); heating system powered by high percent renewable energy, mainly from biomass from residual waste with plans to reach 100 percent renewable sources for heating in most the cold regions in the world (Oslo); innovative program that allows people to exchange trash for transit tokens or fresh produce (Curitiba); projects to get 50 percent of the population on two wheels by 2015 by closing down some major roads to cars and developing an additional 43 miles of bike lanes and requiring all new developments to incorporate some level of vegetation into building designs (Copenhagen).

Lessons to be learned – Flood losses in Europe to ‘increase four fold’ by 2050

Humans have always worried about weather not only on for days and short-terms but also distant future and over longer periods (climate) especially for food security, living and for creation of settlements.  Future Tellers, Horoscope or Science are different forms of predicting the unpredictable depending on cultural, social and economic conditions. For science “what you can’t measure doesn’t exist”, even though there are uncertainties in “weather/climate” sciences as such knowledge rely on models. First we develop models through existing knowledge, we keeting improving knwledge through research. Then in parallel models are developed, tested and improved untill they can reproduce the reality and if so the models become reliable and acceptable. What regards climate and weather we seek answers on when, where, how and to which extent the climate/weather would/can be, also assessing the expected disasters, damage, losses and costs. Such knowledge/data are helpful what regards management and actions.

The best journal in science “Nature, Climate Change” has published data from the most accurate model yet developed showing that annual floods in Europe will increase four fold and the associated annual costs will be 23.5 bn Euros by the middle of the century. About 2/3 of these changes are due to human development and not by climate change. It is clear now that instead of assessing individual flood risks, maximum water discharges over large numbers of river basins or parts of catchments can give much better predictions what regards large-scale and long-term predictions.

China-European Innovative Cooperation For Cleaner Cities

Chinese and European experts are cooperating, through meetings, conferences, roundtables and workshops, to gain valuable insights into clean energy. Government and business stakeholders highlighted their willingness to strengthen EU-China cooperation on energy security. Sustainability concepts to do more with less harm are developed in Europe for successful applications of the “reduce, reuse, recycle” hierarchy in industry. Based on this, it is possible to re-design products that, after their useful life, they can be much environment-friendly than what is possible today.

The China-Europe cooperation involves a “Demo Zone Initiative” that supports the city of Urumqi in technological innovation, low-carbon urban planning and circular economy by introducing successful EU experiences and technologies. Urumqi is one of the most pol- luted cities in China and the world because of heavy air pollution from industrial sulfur dioxide emissions. The dominant industries are petrochemical, metallurgical and textiles. The goal of the “Demo Zone Initiative” is to establish a win-win method to be replicated in other Chinese cities using a toolkit for urban action and district energy planning with local project financing and public-private partnerships (PPP).

The Chinese-European cooperation, by being inter-sectorial and inter-disciplinary, has synergistic effects that bring added value to education, public awareness, construction, industry, transport, environment, decision-making, capacity building, education, research and development.

China’s Energy Needs – The Water Resources Set The Roof for Energy Use.

In production strategies, more energy means more work gets done, it can also mean more conservation in energy can generate more work. The difference between these strategies is not only saving energy to get the same amount of work but it is the enormous saving of assocaited waste and pollution which in turn means more quality life, water for healthy food and conservation of environment. This makes the essence of modern sustainability, three-fold saving “energy-water-food” with enormous feedback on health, life quality and biodiversity. In this context, a  strategic question in the use of energy for production and living is: how much is enough in energy use and consumption? Can we humans use and consume as much energy as we wish and what are the limits? Are there any roofs for our energy needs for consumption, in this case what are these roofs, how they can be defined, monitored and implemented?

Indeed, global water scarcity started to be more pronounced is not because water on our planet is becoming less but it is because our energy needs for consumption are becoming not only unrealistically high but they are currently unaffordable and even inaccessible for future generations.

MENA – Impacts of Political Instabilities and Wars on Water Resources.

Since late 1040’s, water resource management in the MENA region (Middle East and North Africa including Algeria, Bahrain, Egypt, the United Arab Emirates, Iran, Iraq, Israel, Yemen, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Saudi Arabia, Syria, Tunisia, Qatar, the occupied Palestinian territories and Western Sahara “former Spanish Sahara”) faced several negative impacts as a result of asymmetric power relations, volatile political situations, political instabilities with periodic/continuous conflicts and wars. Under such conditions water policies were mainly focused on national short-term interests for securing supply and services with little, or even no, consideration to entire water cycle, e.g. the large-scale and long-term trans-boundary nature of the water resources in regions with shared rivers and/or shared groundwater resources. Furthermore, periodic conflicts and wars hindered developing appropriate economic-political instruments for efficient water-use and flexibility to manage long-term and large-scale supply and demand. Also, Integrated Water Resource Management “IWRM” for trans-boundary waters were lacking coherent policies of equitable and reasonable use, i.e. by being based on such factors as social and economic needs, size of population, access to other water sources, etc. The added-value to national and regional programs from several international donors involved in MENA water issues (the World Bank, UNDP and USAID) was therefore rather limited.

In addition to trans-boundary political conflicts, national governance is/was hampered by a lack of coherent laws, seemingly incompatible political interests, weak environmental legislation for over-exploitation of groundwater and over-consumption of water for irrigation with associated pollution and in-economic use of water. Pesticides, herbicides, industrial pollution, agricultural and household waste resulted in serious impacts on water quality, in addition to saline intrusion of the aquifers near the seas.

The Water Crisis in the MENA Region – Making the Most of Scarcity.

Water in the MENA region is integrated into the wider economic policies of the countries of the region and therefore water issues have to be addressed to multi-sectorial audience to bring about a broad reform within the current political and economic climate.  Indeed, MENA is using more water than it receives each year and most of the countries in the MENA region cannot meet current water demands. The situation is likely to be worse and per capita water will fall by half already before 2050, with serious impacts for the region’s already stressed aquifers and natural hydrological systems.

In coming decades, economies and population structures will force enhanced demands for water supply and irrigation, in addition to new needs to address industrial and urban pollution. Future management of water resources will be further complicated as the major part of the region’s water flows across international borders and climate change will introduce complex shifts in rainfall patterns. If the MENA region will not be able to meet these combined challenges the socio-economic consequences could be enormous, e.g. erratic drinking water services, more expensive desalination for cities and there would be needs for emergency supplies during droughts. Unreliable water resources, depletion of aquifers, service outages will cause stress on expensive infrastructure, depress farmers’ incomes, intensify local/regional conflicts with short- and long-term effects on economic growth and poverty, social tensions within and between communities, and increasing pressure on public budgets.

Post 1960s water policies of securing supply and services require switch toward better water management with consideration to entire water cycle and not the separate components, also use of economic instruments for water efficiency and flexibility to manage variations supply and demand. Changes in planning should include integrating water quality and quantity and consider the entire water system, promotion of demand management, tariff reform for water supply, strengthening of government agencies and stronger enforcement of environmental regulations. Also, shift from low-value uses to higher-value needs. Equal involvement of all stakeholders in water management policies including stakeholders outside irrigation, water resource management, and water supply and sanitation, e.g. within agriculture, trade, energy, real estate, land, finance, and social protection.

Reforms for sustainable socio-economic water management should involve: political and technical policies; effective interactions with non-water decision makers; accountability of government agencies and water service to the public as well as transparency for good and bad performance.

Renewables Changed Bitter AC-DC Rivals to Successful Marriage

Thomas Edison and his Direct Current “DC” technology lost the historical so-called “War of the Currents” to Alternating Current “AC” in the 1890s that was championed by the Edison rivals Nikola Tesla and George Westinghouse. The argument was AC was far more efficient at transmitting electricity over long distances.

Edison, inventor of light bulb and the world’s first DC power distribution system in 1882 was not totally wrong to insist on the needs for DC distribution grid. The technological advantages of AC over DC at that time dedicated the success and expansion of AC power distribution grids initially developed in 1886 by Westinghouse and Stanley with major inputs from Nikola Tesla. An AC power system allowed voltages to be “stepped up” by a transformer for distribution, thus reducing power losses, and then “stepped down” by a transformer for consumer use. The AC technology became gradually mature for large-scale grid up-scaling. However, the advances of DC power distribution for long-distance power transmission took a revival in 1954 when the Swedish company ASEA, predecessor of ABB, the Swiss maker of power and automation equipment, linked the island of Gotland to mainland Sweden with high-voltage DC lines.

However, by late 19th century science and technology was too blind to recognize the problems associated with the use of fossil fuel, e.g. coal, oil and gas, for production and distribution of electric power. During the 20th century it has been an accelerating pile-up of threats not only from fossil fuel consumption what regards the green-house impacts on climate, but also the associated impacts on water resources from fossil fuel production in form of enormous and irreversible environmental pollution and degradation of ecological and water qualities.  With birth of renewables, e.g. solar, wind, geothermal, hydropower and wave power, and the continuous advances in associated DC and smart technologies the advantages of DC distribution grids became once more apparent. They are economic for high-voltage and high-capacity runs over very long distances, they are better suited to handle the electricity produced by solar and wind farms, which starts out as direct current.

Follow the emerging needs for transformation to renewables and the implementation of more sustainable management policies.

China’s Renewable Challenges for Efficient and Optimized Grid

China’s need for energy to serve its citizens and industries will accelerate tenfold in the period 2000-2035, i.e. from 1TWh to 9.6 TWh. Until now the share of renewables in China’s energy mix is about 17% while the major part of its energy, about 80%, is provided through fossil coal.

China’s challenges are related to its relatively very young renewable programs, and that the regions of highest energy demands are not matching China’s geographic distribution of its renewable energy production. Another challenge for China is the integration of its regional grids to a more efficient and optimized grid especially with consideration to the additional emerging renewable energies and the associated needs for storage. With these challenges a clear energy saving policy is needed for integrating renewable energy into China’s system. This is not an overnight and easy task especially if sustainable policies have to be taken in consideration for the reduction of greenhouse gas emissions which will remain to be one of the most serious difficulties for China not only from climatic view point but also from environmental and air quality prospective.

South Africa’s Sustainability Challenge: Food; Energy and Water

By 2030 South Africa will have 60 million people, i.e. more than double of today’s population, to feed. Today’s water and energy resources are already used up for living and providing food. The only solution is SUSTAINABLE planning and recognizing the way these three resources, i.e. food, energy and water, are INTER-CONNECTED.  We need sustainability as much as sustainability needs us.

Canada Oil Sands – How Sustainable is Sustainable?

 

Increasing energy demands and pressures on Conventional Light Oil “CLO” of the Eastern Hemisphere (85% of the global inventory) have shifted the focus to Unconventional Heavy Oil “UHO” and Conventional Tar Sands “CTS” deposits around the world. The major part of “UHO” is in the Western Hemisphere (69% of the inventory), mainly the USA, while the majot part of “CTS” is being found in Canada. We have to keep in mind that the world inventories of UHO” and “CTS” may, indeed, exceed the global inventories of “CLO”.

Unconventional oil sources and oil sands are created in the same way as conventional oil—that is, through the combination of organic material, heat, and pressure. The main difference between the two is their ability to move underground. Conventional oil migrates upward due to its buoyancy. This oil moves through pathways in the underground rock in its fluid state and becomes trapped between impermeable layers of rock. Unconventional oil and oil (tar) sands, meanwhile, is formed in sealed spaces of rock, or being mixed with sand, and is not able to move up; it therefore remains in the source rock/sand, trapped in pores or unconnected pores. Unconventional oil and oil or tar sands are therefore produced and extracted using techniques other than conventional method used in Conventional Oil industries. Governments across the globe are investing in unconventional oil sources due to the increasing scarcity of conventional oil resources. 

Due to the different nature of accumulation and existence in underground formations and difficulties associated with production/extraction of unconventional oil and oil sands there are multiple of additional environmental threats and climatic impacts. Production and extraction of unconventional oil and oil sands consume much more water, have enhanced negative impacts on the environment in terms of produced waste, contamination and pollution especially what regards degradation of aquatic life, eco-systems and bio-diversity. Moreover, carbon dioxide emissions from the production and extraction of unconventional oil and oil sands are relatively higher, up to 20%. Indeed, the climatic and environmental (http://blogs.worldwatch.org/revolt/unconventional-oil-implications-for-the-environment-and-greenhouse-gas-emissions-2/) impacts of unconventional oil and oil sands are not fully understood and consequence assessment analyses are fragmentary, incomplete and far from being representative especially what regards the large-scale and long-term impacts and threats.

Transformation to Clean Energy – The Canadian Challenges

The world is currently facing growing pressures for transformation to clean energy in order to mitigate the environmental and climatic impacts of traditional energy sources. For Canada transformation to clean energy is still a big challenge, however it represents a unique opportunity for traditional energy producers and clean energy producers to team-up. These players have to come-up with a coherent task with the government to assure further development of traditional sources of energy in environmentally responsible manner while at the same time start grow more quickly to clean electricity sector. Resolving these issues will make it possible to meet the challenges for the transition to clean energy.

Similar challenges for countries with high carbon dioxide emission per capita, also, exist around the world but not all the countries have the same possibilities and resources for full and quick transformation to clean energy because of necessary huge capital investments, access to the required high-tech infra-structure/expertise and above all the political will. However, countries with low carbon dioxide emissions per capita, e.g. in Africa and South America, have to implement policies and encourage promotion of clean energy production while building up their technology, industry and production sectors.

Lessons to be learned – The Sustainability Program of North Ireland

While there are no “standard maps” for achieving successful sustainable socio-economic developments everywhere in the world, yet we can learn from exiting strategies and solutions. Naturally, nations around the world have own conditions, structures, needs and may exist in different stages of development with complex internal and external political, economical and trade relations. Assessing the existing models and strategies helps formulating short and long-term roadmaps that are appropriate and suitable to the socio-economic needs and conditions. Successful socio-economic developments can’t be based on random actions and have to follow robust strategies emanating from effective, collective and coherent interactions between all sectors and on all levels. In this context, cloudy and conflicting interesting “within and between” nations can be major obstacles for achieving sustainable socio-economic developments.

An example on how to build national roadmaps for bring about successful socio-economic developments even under economic constrains is given here.

Mechanized Agriculture in Sudan – Collapse of Sustainable Land-Water Management.

UNEP along FAO, ICRAF and a number of Sudanese NGOs and institutes describe how and why the agricultural sectors in Sudan were gradually degraded and moved rapidly towards more or less total collapse because of environment over-taxation. Since the introduction of mechanization of rain-fed agriculture by the British in 1944 several negative impacts, due to lack of control and planning, were piled up during the last half of the 20th century. This has caused large-scale destruction of environment and triggered severe negative impacts in other sectors as well. The traditional and mechanized agriculture account for 55 and 45 percent respectively of the rain-fed cultivated area. The importance of the irrigated sub-sector is reflected in the fact that while it makes up only 7 percent of the cultivated area, it accounts for more than half of the crop yields. However, irrigated land has own problems. Rapid, uncontrolled privatization, random investment and failure to couple education and research to market and society needs are major causes.

Management of land-water resources in Africa is IMPERATIVE. However, past experiences show not only major failure but the great threats of the blind and random implementation of imported technologies, e.g. Sudan where its cultivable land is about 42 percent with frequent claims that it is the potential ‘breadbasket’ of Africa and Middle East. Agriculture, the largest economic sector in Sudan, became the heart of some of the country’s most serious environmental problems: wide-range of land degradation, riverbank erosion, invasive species, pesticide mismanagement, water pollution and canal sedimentation. Also rangeland’s vulnerability to overgrazing is high and its overlap with cultivation is a major source of potential conflict. The significance of these threats cannot be underestimated: not only are 15 percent of the population partly or wholly dependent on imported food aid, but the population is growing, per hectare crop yields are declining and the enhanced competition over scarce agricultural resources.

The agricultural sector in Sudan is the main source of sustained growth and backbone of Sudan’s economy. Unfortunately, the sector’s economic stake is declining more and more with the emergence of the oil industry. Sudan continues to depend heavily on agriculture, whose share fluctuates around 40 percent of the GDP. The crop and livestock sub-sectors together contribute 80 to 90 percent of non-oil export earnings. With these trends the country will face more unemployment and famine as fifty-eight percent of the active workforce is employed in agriculture and 83 percent of the population depends on farming for its livelihood.

Global warming adds new threats as the agricultural sector in Sudan is highly vulnerable to shortages in rainfall and there has been substantial decline in precipitation and climate change models predict that this trend will continue. Without major action to stop the wave of de-gradation and restore land productivity, the natural resource base will continue to shrink, even as demand grows. Resolving this issue is thus central to achieving lasting peace and food security.

Amazing High Tech Farm – A Complete Meal Using A Mobile!

Eric Maundu, owner and founder of “Kijani Grows” (“Kijani” is Swahili for green), isn’t a farmer, he’s an engineer with a computer science degree from USA. Maundu himself ran from agriculture in his native Kenya- where he saw it as a struggle for land, water and resources. In the USA he felt the negative impacts of urbanization, industrial waste and traffic pollution on contamination of soils and degradation in land-water resources. In industrial/urban areas and cities, freeways, roads, light rail and parking lots so there’s not much arable land and the soil is contaminated. With these threats in mind he realized he could farm without soil, with little water via aquaponics and with possibilities to use “self-cleaning” and recycling as well as that he could apply his robotics background to farming. An amazing combination of: physics; chemistry; biology; ecology; and computer science in one system.

No soil, instead Maundu is growing plants using fish and circulating water. It’s called aquaponics- a gardening system that combines hydroponics (water-based planting) and aquaculture (fish farming). It’s been hailed as the future of farming: it uses less water (up to 90% less than traditional gardening), doesn’t attract soil-based bugs and produces two types of produce (both plants and fish)., i.e. a full meal!

Maundu- by being trained in industrial robotics- has taken the agricultural craft one step further and made his “aquaponics” smart. Using sensors (to detect water level, pH and temperature), microprocessors, relay cards, clouds and social media networks. Maundu has programmed his gardens to tweet when there’s a problem, e.g. not enough water or when there’s news, e.g. an over-abundance of food to share. With these smart solutions the same information can be shared with farmers in Iceland and China.” Maundu believes that by putting gardens online, especially in places where solar-powered gardens are totally off the grid), is the only way to make sure that farming remains viable to the next generation of urban youth.

DIY – Biogas from leftover food and animal manure.

Waste from animals and household can have negative and harmful impacts on the environment, i.e. land-water resources, as well as on health because of degradation of sanitation and living conditions. However, when sorted and treated can be useful sources conservation of natural resources, for improves economy, for producing energy, (biogas or electricity, and fertilizers e.g. different forms of organic fertilizers). It is simply because leftover food and animal manure are organic matter rich in carbon which is a basic element for production of biogas. Breakdown of organic matter in the absence of oxygen, i.e. anaerobic digestion with anaerobic bacteria, can produce biogas. Biogas can, also, be produced by fermentation of biodegradable materials such as manure, sewage, municipal and green waste, plants and crops.

Note: In order to get the best possible out-put from DIY “DO-It-Yourself” you are strongly encouraged to address questions, give comments and contribute in discussions. This will in addition to bringing more clarity, will also contribute in making modifications and further adjustment or even developments for better adaptation to local conditions, e.g. climate, mixture of waste, availability of construction material, running conditions and maintenance aspects.
