Category: Agriculture & Farming

Farming and animal husbandry are typical activities in rural communities and the motor of economy especially in the developing countries, e.g. Asia, South America and Africa. Supporting these basic activities is imperative for achieving sustainable socio-economic developments in many developing countries. Successful urbanization strategies around the world are very much related to supporting rural communities and integrating them with the rest of society through effective management of farming and animal husbandry sectors.

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.

How Abnormal is Abnormal – Flooding in MENA and Africa

Coordinated data on weather disasters and the associated impacts on population are becoming increasingly important, as the collective damage can be enormous. Abnormal weather conditions started to be more frequent probably becuase of global warming. Just during the first part of May 2014 a series of abnormal weather conditions took place in many parts in Africa and the MENA regions, below are some examples. These abnormal events of weather conditions are very rare to take place in these regions on times scales of at least several decades. These abnormal weather conditions that hit many countries in the same time-period can be an indication of large-scale phenomena/effects, but what???

6 May 2014, Burundi. Flooding kills 50 after torrential rains and storms that triggered mudslides, landslides and swept away homes, cut off roads and power, injured people, destroyed schools, houses, goods and public infrastructures. Houses in the poorer parts are often made of mud bricks and can’t resist against water and mudslides and landslides.

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.

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.

Berlin/IPCC – Greenhouse Gas Emissions Are Still Accelerating

Berlin, 13 April – A new report by the Intergovernmental Panel for Climate Change “IPCC” indicates that global emissions of greenhouse gases have accelerated despite reduction efforts. The report, also, shows that many pathways to substantial emission reductions are available. As, many other atmospheric pollutants and toxic compounds are expected, also, to be associated with the emissions of greenhouse gases, then enhanced degradation in world aquatic and ecosystems will be taking place in parallel. In addition, the sites where these emissions are taking place there would be additional local and regional problems as well to the workers, in particular “high occupational levels of pollution” and the public health of individuals “air quality” in general.

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.

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.

Do-It-Yourself: How Does Methane Biodigester Work?

There are many technical approaches and levels of complexity for turning leftover food and manure till biogas. Understanding the underlying science and concepts in a simple way can help to gradually construct and develop own solutions to achieve affordable, efficient and friendly fuctional facilities.

You have input material, i.e. initial reactants that are processed under reduced “anaerobic” conditions, i.e. air free from oxygen through using sealed containers, at a suitable temperature, and more or less neutral conditions. The temperature range can vary around 40 degrees celsius, and to be controlled using heat from the sun along with suitable insolation if necessary, i.e. depending on region and season. The initial reactants have to be crushed to facilitate the bacterial reaction where we have two types of bacteria, e.g. those creating acidity and those producing methane. There are high-energy organic matter, i.e. those with high sugar and high carbohydrate content, and low-energy organic matter such as grass and manure (more or less consumed organic matter). High-energy food promote production of acidity, i.e. “acid” type of bacteria while the other methane-producing bacteria are much more accessible in animal manure. The liquid leftover “effluent” from the whole process may be used fertilizer, however it can be beneficial to do some analysis to see the quality in relation to the composition of the reactants. In this context, adjustment of the control parameters, i.e. temperature, duration and acidity as well as the composition of reactants can be part of development and optimization of the production facilities.

Would Algae solve our Food, health and Energy Needs?

Our understanding of algae, their unique and rich diversity, is shifting more and more towards finding industrial applications for production of useful products, in particular, food (human food, fish food and animal food), energy and farmaceutical products. There are known methods and tools to extract oil and other valuable products from algae, also to change the genetic content and chemical composition of many algae.

Many and many organizations give lots of money for research for commercialization of algae. Research takes is typical path fuelled by society needs, human hopes for prosperity and fears from environmental threats. In this amazing journey of what we are right now and where we are heading to, there are several important facts to be known, e.g. benefits and threats. There are, also, key interests in understanding the potential of artificial photosynthesis as a new path, not yet fully understood, for production of energy.

Algae are “biochemical reactors” that can recycle carbon to produce organic compounds in different forms, which indeed is the origin of all the gas and oil reservoirs around the world. Multi-hundred-million dollar industries have invested in many products, e.g. sushi wrap, oils, dental impression, ice cream thickener, cosmetics, medical products, plastics… etc. They still invest more and more money for production of energy-rich food, biofuel from algae and use of wastewater to grow algae as well as for the extraction of other useful products like coloring agents and anti-oxidant, agro-culture business for production of food in the fish and shellfish industries.

Basic research is needed, and even imperative, to solve central bottleneck in algae processing technology ranging from cultivation, harvesting, extraction of desired products, processing and refining. Micro-algae are known to grow very fast and there is commercial potential in industrial microbiology where molecular biology in combination with aquaculture and marine farming can yield hybrid and novel technologies. Unlike industrial small-scale microbial technologies, e.g. cheese, beer, alcohol that are based on “closed systems” trying to cultivate algae on large-scale, i.e. in open systems, is a great challenge. Algae are now looked upon as the most sustainable known potential source of biofuel. The challenges are transferring the many different types of small-scale bioreactors to open systems for growing algae at large scale. Up-scaling of algae-based technology leads to emergent issues that are not fully controlled, e.g. competitor algae, predators and diseases (bacteria and viruses). Up-scaling to large-scale open systems, therefore, requires solving a wide-range of difficulties and threats including those arising from varying weather conditions, e.g temperature, and much work is still needed.

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.

Feedback Impacts of Land-Water Qualities on Agricultural Technologies.

Agricultural production is very much dependent on land-water resources and in recent decades there have been trends towards new agricultural solutions either to substitute the increasing degradation in land-water qualities or to find new agricultural alternatives more suitable for arid and semi-arid climate.

Degradation in water quality resulting from waste, pollutions and sanitation on the one hand, and reduced land quality due to decreasing soil fertility, man-made technological interferences “dams”, soil erosion and climate change on the other, triggered new shifts in agricultural technologies. Traditional agricultural techniques are becoming more and more dependent on artificial fertilization either to compensate for decreasing soil fertility and/or to increase soil productivity.

Chemical pesticides are still in use, inefficient irrigation routines and further pressures on water resources have, also, caused gradual degradation in land-water resources in particular the large-scale and long-term negative impacts on water resources.

These trends have forced shifts towards new agricultural technologies that either rely on less land and indoor green-house solutions and/or what is known as “complete liquid fertilizers” as well as clean sterilized organic-fertilization. These solutions, foliar spray, fertigation programs, hydroponic solutions, aireal/soil application of “liquid complete” and/or “sterilized clean organic” ferilizers” have new advantages. However they either shifted focus to alternative solutions that may require additional costs, i.e. making food production less economic, or made farming and agriculture that can not afford the new technologies to continue their “business-as-usual” traditions.

WHO – Air Pollution Is World Biggest Health Risk – Air Quality Guidelines

Air pollution has become the world’s single biggest environmental health risk. According to WHO it is linked to around 7 million death or nearly one in eight death in 2012. The new figures are more double previous estimates and suggest that outdoor pollution from traffic fumes and coal-burning, and indoor pollution from wood and coal stoves, kill more people than smoking, road death and diabetes combines.

The document is WHO’s Air Quality Guidelines Global Update 2005. These Guidelines offer guidance to policy-makers on reducing the effects on health of air pollution for the four most common air pollutants – particulate matter, ozone, nitrogen dioxide and sulfur dioxide. Also, issues affecting the use of the guidelines in risk assessment and policy development.

This document contains Part (1) Application of air quality guidelines for policy development and risk reduction; Part (2) Risk assessment of selected pollutants (Particulate matter, Ozone, Nitrogen dioxide, Sulfur dioxide).

Air Pollution Is An Increasing Global Threat to Public Health and The Environment

Air pollution is a worldwide problem especially in many big cities and industrial areas around the world. Emission of fine particulate matter (e.g. aerodynamic diameter ≤ 2.5 µm; PM_2.5) , chemicals (e.g. biogenic VOC) and pollutants (e.g. heavy metals), and associated photo-chemical reactions (e.g. production of tropospheric ozone) in the atmosphere as well as in-cloud interactions (e.g. acid rain) experienced dramatic changes since the industrial revolutions. Concentrations of hazardous pollutants in global atmospheric air masses, dry and wet precipitates have been subject to gradual increasing reaching harmful levels for air-quality what regards human health (e.g. lung cancer, mortality) and the environment (e.g. negative impacts for forests and vegetation and quality of life in aquatic eco-systems) in many places around the world.

Climate change influences air quality through several mechanisms, including changes in photochemical reaction rates, biogenic emissions, deposition/re-suspension, and atmospheric circulation. Several techniques/approaches were used in such studies including atmospheric chemistry, climate model inter-comparison, high-resolution satellite observations together with a global atmospheric models and extensive compilation of surface measurements to better represent global air pollution exposure.
