Forestation Programs.



Forestation means establishment of a forest naturally or artificially on an area which was previously for forests or not so as to cover the area with tree or forest.
Forests cover a third of all land on earth, providing vital organic infrastructure for some of the plane’s densest, most diverse collections of life. But in the huge impact of the world is deforestation. Deforestation can be define as, the unscrupulous and indigenous forest and wood lands. There are many reasons of that, such as
  • ·         Deforestation also occurs due to overgrazing and conversion of forest to pasture for domestic animals
  • ·         Peoples involves cutting trees for sale as timber or pulp.
  • ·         It employs heavy machinery to remove cut trees and build roads.
  • ·         Mining, industrial development and hydroelectric power plant projects are also causes of deforestation.
  • ·         Dams open the previously inaccessible forest and damage ecosystems.
  • ·         Other reasons includes fire, pest, etc.

Effects of deforestation are,

  • ·         Deprivation of shelter for birds, insects and food for animals and human beings.
  • ·         Deceased oxygen and increased carbon dioxide.
  • ·         Scarcity of fuel wood.
  • ·         Increase draughts.                                                 
  • ·         Melting of ice caps causing floods.
  • ·         Increased soil erosion.
  • ·         Increased pollution.

Forestation Programs.


  • ·         Use of pesticides to reduce damage to forest.
  • ·         Control the forest fire created by human activity due to carelessness.
  • ·         Use of modern technology.
  • ·         Reduce demand though technological interventions.
  • ·         Strengthening the central and state forestry administration and institutions.
  • ·         Expansion of forest area can be achieved by implanting trees in forest with people’s participation.
  • ·         Celebrate environment day to create awareness among people about how forestation can help in improving environment.

Importance of forestation program.
            The importance of forestation cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
  • ·         Forest pump out oxygen we need to live and, absorb the carbon dioxide we exhale.
  • ·         Nearly half of all known species live in forests, including 80% of biodiversity on land.
  • ·         Many millions more live along or near forest fringes.
  • ·         By growing a canopy to hog sunlight, trees also create vital oases of shade on the ground.
  • ·         Large forests can influence regional weather patterns and even create their own microclimates.

Group 26- Forestation programs

Group 10- Forestation programs

By planting 50 million trees on our national forests, we are investing in healthy forests for today and for future generations. Consensus on the need for international co-operation to combat climate change has resulted in increased attention to the role of forests in storing carbon and the large quantity of C02 emissions that could be avoided if deforestation was halted. Deforestation and forest degradation are the second leading human cause of CO2 emissions contributing to global warming according to the Intergovernmental Panel on Climate Change. It is estimated that deforestation and forest degradation account for approximately 17 percent of global greenhouse gas (GHG) emissions. Furthermore, tropical forests capture and store carbon – since the turn of the century tropical forests are estimated to have removed 22-26% of all human caused carbon emissions.

Developing countries have an excellent opportunity to pursue low-carbon development strategies going forward. Many low and middle income countries are seeking to pursue the twin goals of development and combating climate change. Deforestation and degradation represent over one third of total emissions in developing countries, where many large tropical forests are found.
The Sustainable Development Goals the Sustainable Development Goals underline the need to balance objectives and potential trade-offs between poverty reduction, growth and sustainability. Trade-offs between climate change objectives and other goals International efforts to help developing countries decrease deforestation rates must balance carbon reduction and development goals and strive to formulate clear, coherent models of change.

Several mention the growing agreement on the need to further encourage and promote sustainable livelihoods for those living in or near forest areas and to address land-use issues as a necessary step in reducing deforestation rates and CO2 emissions. Additionally, the drivers of deforestation are often factors outside of the forest sector and therefore programmers designed to halt or reduce deforestation must address a broader range of related issues, including: land tenure, agricultural policies, the potential for climate smart agricultural practices, alternative livelihoods, livestock and gazing practices, urban expansion, mining policies, and other social and economic drivers of deforestation and change in land use.



These challenges seem to stem from unanticipated obstacles and capacity gaps that need to be addressed prior to full programmer implementation. Recent evaluations highlight the complexity of initiatives in the sector, the slow pace of progress and the need for programmers to adopt a cross-sectorial approach. Not only is a cross-sectorial approach needed, but bilateral development providers also need to focus on environmental policy integration and the overall coherence of their international development co-operation portfolios.

A recent evaluation by Belgium found that while many of their programmers had positive results in stabilizing or increasing the land area covered by forests, greater attention could be paid to negative environmental externalities, such as the impact of other programmers on forest coverage.

Community Forestry Management (CFM) has been identified as one of the best approaches for sustainable forest resource management and livelihood enhancement of the community’s dependent on forest resources. The CFM approach recognizes that the communities themselves are in a better position to protect forests, reduce forest degradation and deforestation provided, that they are empowered and facilitated with knowledge of the ecosystem and best practices, technologies, market linkages, access to credit and ability to partner with the Government, private sector, NGOs and other entities.

The goal of this four year “Sri Lanka Community Forestry Programme (CFP)” is “to improve the management of natural resources to support livelihoods and contribute to poverty reduction in the dry and intermediate zones.” The CFP is designed in line with the Haditha (Green) Lanka Strategy and Action Plan (2009) and Caring for Environment - National Environmental Action Plan for 2008 to 2012 (2008).

  • The project started field operations in October 2012. 
  • By March 2013 work has been initiated in 24 sites and community level Forestry Management Plans are being prepared in those sites. Plan preparation will be over by May 2013. 
  • In 2012, productivity was enhanced in 3,402 home gardens 
  • Work in another 67 sites will be initiated within the first quarter of 2013 
  • Forty-five (45) motor bikes and thirty-five (computers) were provided to the Forest Department to distribute among its field offices, thereby helping to improve their capacity and access 
  • A Programme Management Unit states stablished at the premises of Forest Department to facilitate the implementation of the programme.

Group 10-  Waste Management Strategies

Waste management or waste disposal are all the activities and actions required to manage waste from its inception to its final disposal. This includes among other things collection, transport, treatment and disposal of waste together with monitoring and regulation. It also encompasses the legal and regulatory framework that relates to waste management encompassing guidance on recycling.

waste can take any form such as:
  • Liquid
  • Solid
  • Gas
 Each form has different methods of disposal and management. Waste management normally deals with all types of waste whether it was created in forms that are industrial, biological, household, and special cases where it may pose a threat to human health. It is produced due to human activity such as when factories extract and process raw materials. Waste management is intended to reduce effects of waste on health,  aesthetics and environment.

It builds on and retains the core principles of the 2006 Strategy, and places a renewed emphasis on the Waste Hierarchy.

strategies:

  • development of a waste prevention programmes.
  • development of a new recycling target for local authority collected municipal waste
  • introduction of a statutory requirement on waste operators to provide specified data on commercial and industrial waste
  • new and more challenging collection and recycling targets for packaging and waste electrical and electronic equipment
  • introduction of a landfill restriction on food waste
  • implementation of legislation on carrier bags
  • development of detailed proposals for an Environmental Better Regulation Bill
  • minimizing or avoiding adverse impacts on the environment and human health.
  • Allow economic development and improvement in the quality of life
  • Conserve resources of water, energy, raw materials and nutrients
  • Control pollution of land, air and water.
  • Enhance business performance and maintain corporate social responsibility.
  • Improve occupational health and safety.


Strategies of medical waste management

  •         Development of awareness among the service provider by sensitization.
  •          Proper capacity development of the service providers by providing training.
  •          Development of in house management of waste.
  •          Development and adoption of option for the final disposal of waste depending upon the situation, type of hospital, amount of waste production.  


Industrial waste management

Typical techniques :
  •      Waste avoidance and minimization
  •          Landfills
  •          Incineration
  •          Deep well injection 
Effective strategies

  •     The 4 R’s strategy
  •         Industrial symbiosis

Energy efficient solutions in buildings -G14


Energy efficient solutions in buildings

Buildings are of different kinds and types in the modern world with the technological development. So, the energy usage in the buildings were increased as a result of the technological development. Major areas where the buildings use energy are in heating, ventilation, air conditioning, lighting and in major appliances such as water heating, refrigerators, freezers, dryers etc. and as result of these energy consumption in the buildings are increasing day by day. It is considered that buildings are the largest energy consumers in the world. So that to reduce this matter, energy efficient solutions were introduced to modern buildings.

Energy efficient buildings are designed with a low consumption of energy as possible. Energy efficiency in buildings can be defined as a cost-effective way while contributing to the environmental climatic challenges by producing economic and social benefits, anticipating regulatory requirements and reducing or elimination of greenhouse gas emissions. There are 4 categories of energy efficient buildings which can be identified in modern buildings. Those are low energy buildings, passive energy buildings, zero energy buildings and plus energy buildings. Zero energy building is a building with zero net energy consumption which it is achieved by producing same or higher amount of energy that is used by the buildings and also it has zero carbon emissions.

 Energy efficient buildings can be constructed by using quality building and insulation materials which prevent heat loss in the building and by producing natural lighting and ventilation to the building as much as possible.
Natural lighting and ventilation can be supplied for the building with the use of wind direction, cross ventilation, landscape to channel cooling breeze and the sun direction and those can be used in places such as courtyards, louvers, openings, verandahs etc. New technologies for heating, cooling, and ventilation not only can achieve large gains in efficiency, but they can improve the way building systems meet occupant needs and preferences by providing greater control, reducing unwanted temperature variations, and improving indoor air quality. Innovations include glass coatings that reduce absorption and re-emission of infrared light, thermal conductivity improvements (e.g., multiple panes of glass, filling gaps between glass panes using argon, krypton, or xenon,13 and improved frame design), and the use of low-iron glass to improve visible clarity.  

Lighting quality plays an essential role in buildings and it uses high amount of energy. A well-designed lighting system can enhance
productivity and the energy consumption. good building and lighting design, window and window covering technologies (such as blinds and diffusers), lighting sensors and controls (including occupancy sensors and light sensors), and lighting devices (LEDs and others) can be identified as main strategies to improve the efficiency and quality of lighting. Good lighting design can ensure that light levels are adjusted to user requirements.

Energy use in buildings depends on a combination of good architecture and energy systems design and on effective operations and maintenance once the building is occupied.
And thus, creating or designing buildings with good energy systems can reduce the energy consumption in buildings. By using energy efficient solutions in buildings, energy consumption and GHG emissions. This will led to a more advantageous and environmental friendly building constructions with increase of sustainability in the buildings.

Forestation Programme

Srilanka is among the world’s most impoverished nations, with a significant young population (48% under the age of 20) entering into their working life and in need of employment. Escalating demand for, and pressures on, land and natural resources from increasing population growth (approximately 1.53%), rapidly rising unemployment, internal migration, and developments in infrastructure and other economic sectors, combined with legislation that is not fully formed and weakly enforced, exposes our forests to unsustainable exploitation and leads to conflicts over rights of access and use. Nonetheless, Srilanka has succeeded in maintaining varied and extensive forests covering more than 10.8 thousand hectares, including plantations and bamboo. They contain biologically unique landscapes and areas of significant cultural heritage, and are potentially highly productive. Furthermore, Srilanka forests are intimately linked to agriculture and in-land fisheries, and to maintaining the sustainability and productivity of both these sectors. Services provided by forest ecosystems include regulation of local water-circulation, mitigation of droughts and floods, and reduction of waterway sedimentation. Forests are, therefore, a key factor in national development, and their sustainable use could provide considerable benefit to our country and her people. Opportunities are arising in international markets for processed and high-value forest products along side potential markets for carbon sequestration. Novel, innovative forms of financing are emerging through ‘payment for environmental services’ for conservation of forest resources and biodiversity. The majority of our rural population are subsistence farmers, 75% of these, as well as landless families, depend on access to natural forest resources for essential products, energy and food, particularly in times of hardship. Forests also provide household opportunities for diversification, supplementary income, and employment created by forest product-based enterprises. It is a challenging task to achieve a balance between economic development and broader community benefits from forests and environmental protection, but one which we cannot afford to ignore. Well managed, equitably developed renewable forest resources can form the basis for a profitable modern economic sector while still maintaining or even expanding their ecosystem functions, biodiversity and ecological variation.
While the forests have substantially provided the basis for rural livelihoods they have also been a source of conflict and exploitation. During the 1980s, the triple-party Government used the forests for cover, and its resources to finance their activities. This  version of our National Forest Programme (2010-2029) considers changing conditions for our forests and society and our role in the global context. It provides strategic directions that place governance at the heart of sustainable forest management and increasing forest contributions to national development objectives.
Benefits of the Afforestation:
Increased Employment:

In Afforestation work, approximately eighty per cent of the total amount of expenditure is incurred on account of wages on such works as soil digging, sowing, weeding etc. which is done mostly by landless and otherwise very poor laborers. A part of the increased population of the next few decades might well be absorbed in the fields of employment that will be opened as a result of availability of vast amounts of raw material. Here against the avenues of employment will mostly benefit the poor and middle class people.
Creation of an Economic Capital:

 
The extensive Afforestation will not only provide direct employment of lakhs of poor people as indicated above but will create a permanent capital of immense value. The increased Afforestation envisaged in the plan when completed is likely to more than double the output of timber.
Increased Food and Fodder Production: 

To the unwary it may appear suppressing how rising of forests will increase the food production. It will also provide grazing facilities and solve the problem of fodder for cattle.
Avenues of Cottage Industry:

The vast amount of raw material that will be available from the increased forests will open up unlimited scope for a number of cottage industries such as furniture, sports goods, match industry, wood carryings, basket making, pencil making, hand-made paper industry, house building etc.
Regulation of Streams, Rivers and Underground Water:

One of the greatest needs of the time is to control and regulate such forces of nature as rain and wind to the best advantage of man. The role of forests in cushioning the beating rain, the intercepting a part of the precipitation and conserving it and releasing it gradually through the springs, needs no further elucidation
Increasing Longevity of Dams and Reservoirs:

The extensive forests that will be raised over the catchment areas of the rivers on which great dams and reservoirs are being built will prevent the erosion of the top soil to a great extent and thereby the silting up of the beds of impounded lakes will be greatly reduced. By reducing the velocity of rushing rain waters, the wooded lands constitute the best insurance against denudations, devastating floods, disappearance of springs and silting up of the beds of reservoirs, canals and rivers. So important is the role of vegetation over the catchment area of our river systems that their proper afforestation must precede every irrigation project.
Disadvantages of Afforestation
1. It comes with real opportunity costs.
One potentially huge drawback of afforestation is the simple fact that it comes with real opportunity cost, where the transformed lands can no longer be used residential developments and agriculture that are highly beneficial to the society through more supply of food and housing for those who need them.
2. It can affect biodiversity.
Under poor management, this method can result in a reduction of biodiversity in the local ecosystem; introduction of potentially invasive and non-native species; modification of particular biomes; reduced stream flow; and loss of agricultural revenue. As you can see, native grasslands that are converted into forests might not be able to contain the same habitat for local species. Also, mismanaged reforestation efforts could result in the production of a monoculture that lacks plant diversity and lessens the number of available habitats for inhabitants of the forest.
3. It can bring some problems of ecotourism. 
If the purpose of afforestation is ecotourism, it may be subject to potential problems that come with ecotourism, such as littering and harm to wildlife.
While you can see the process of afforestation as a positive one, offering a lot of benefits to both the environment and society, it is also accompanied by the fact that it can also bring about some drawbacks. By assessing its advantages and disadvantages, you will be able to build a well-informed opinion on whether it is good for the world as a whole, or not.

Group 6 - Waste management strategies

Waste management strategies
Waste management includes all aspects of the process to manage waste from its manufacture to its ultimate disposal. Waste management is collection, transportation, and disposal of garbage, sewage and other waste products. Waste can take any form that is either solid, liquid or gas and each have different methods of disposal and management.
A number of waste prevention techniques are available, and they are commonly summarizes as the 
3R concept. As ReduceReuse, and RecycleThese are three essential components of environmentally- responsible consumer behavior. This is waste management hierarchy.
Reduce
Reducing the amount of packing particularly can have a great impact on environmental damage. 
Using natural materials can also help. To manage the waste, most effective way is to reduce waste 
before it becomes rubbish.
Following are the some examples:
• Become informed about the environmental impact of products. If not satisfied, search for better alternatives.
• Bulk buy when possible, but don’t buy more than can be used
• Choose products with less packaging
• Choose products with recyclable and reusable packaging
• Carry reusable shopping bags or boxes
Reuse
Following are the some example:
• Donate unwanted clothing, furniture and other goods to charities.
• Use rechargeable batteries rather than single- use batteries.
• Use retreated tires if they are appropriate.
• Carry lunches in a reusable container rather than disposable wrappings
• The introduction of a landfill restriction on food waste.
Recycle
Recycling recovers materials used in the home or in industry for further uses only recycle after trying to reduce and reuse.Recycling has environmental, economic and social advantages.
The most important reason for waste collection is the protection of the environment and the health of the population. Rubbish and waste can cause air and water pollution. Rotting garbage is also known to produce harmful gases that mix with the air and can cause breathing problems in people.
