FAO, EU Help Develop Tank Ecosystem in Podiwewa
The environs of the Podiwewa, a minor irrigation tank in Moneragala was a hive of activity recently as the villagers from Thimbirigas-ara in Buttala joined the Moneragala District Secretary, D.S. Pathma Kulasooriya and officials of the Department of Agrarian Development to plant saplings around the Podiwewa to develop the tank ecosystem.
The Podiwewa is intertwined with the lives of 43 farmer families in Thimbirigas-ara as it irrigates paddy farms and other field crop cultivations while also providing a water source for daily needs.
Supported by the Food and Agriculture Organization of the United Nations (FAO) and the European Union, saplings such as kumbuk, tamarind, mee and karanda were planted on the upstream section of the tank. palmyrah saplings were planted along the downstream edge of the tank bund.
The saplings were provided by our villagers and the Forest Department,” said Gunadasa, the President of the Thimbirigas-ara Farmers Organization. “We planted around 600 saplings in a one kilometre area. Each farmer has now taken on the responsibility of nurturing around 10-15 of these plants.”
The saplings that were planted in the upstream section of the tank (gas gommana) will eventually become natural wind barriers during high winds, reduce evaporation and erosion, and will protect the tank from illegal encroachments.
In Sri Lanka, the ecological segments of the village tank system play vital roles. The downstream reservation (Kattakaduwa) is the stretch between the tank bund and paddy fields.
It contains flora which acts as a downstream wind barrier, minimizes seepage and prevents polluted water containing salt and heavy metals from flowing into paddy fields.
The soil ridge (iswetiya) of the tank diverts sediments/silt, thereby preventing soil erosion.
The waterhole (godawala) in the tank inlets act as a source of drinking water for wildlife and livestock while trapping the sediments, which would otherwise flow into the tank.
However, most of the ecological components of village tanks that have existed for centuries are disappearing. Encroachment for cultivation purposes and removal of trees for various uses are some of the main reasons. The cause stems from a lack of awareness on the importance of the tank ecosystem. FAO Technical Officer (Moneragala District), Ranjith Pushpananda said, “developing the ecosystem of irrigation tanks is crucial as tanks mitigate the effects of natural disasters such as drought and floods.”
“For instance, the storage of excessive runoff water in tanks during heavy rains reduces flooding and conserves water for use in the dry season. Irrigation tanks also enhance biodiversity. The importance of the tank ecosystem was shared with the villagers of Thimbirigas-ara.
The villagers constructed the soil ridge of the tank and the waterhole prior to the tree planting initiative,” he said. Gunadasa said, “We became aware of how the environment helps us and the importance of protecting the tank and its surroundings.
At a time when trees are being cut down and forests are being cleared, planting saplings on the tank bed of the Podiwewa is an example to villagers that depend on tanks. The future generation of Buttala will greatly benefit from it.” The Podiwewa is being rehabilitated by FAO under the European Union Support to District Development Programe (EU-SDDP) which has a total financial envelope of EUR 60 million. Improvements to the irrigation channel and spillway of the Podiwewa, widening of the tank bund and improving the access road to the tank are ongoing. Once rehabilitation works are completed, the farmers of Thimbirigas-ara will conduct regular ordinary maintenance of the tank and will continue to conserve the tank ecosystem.

Concerns deeper than the Ocean
Life is believed to have started in the oceans. Oceans are described by scientists as the origin of life being an island nation, the ocean is never too far from us and our lives are very much linked to it. We know the beauty as well as bounty the ocean brings us. The World Oceans Day being June 8 conceived and adopted in 1982 at the Earth Summit held in Rio De Janeiro, Brazil gives an opportunity to recognize the importance of the underwater world. The law and the institutions of justice are pillars of stability in our communities, it is vital that, they remain strong and relevant in times of crisis too.
Coastal and marine resources
Sri Lanka is a small island in the Indian Ocean with a coastline of about 1,760 km. The ‘territorial limits’ of the island extend to 12 miles (19.2 km) offshore, beyond which lies the ‘contiguous zone’ under the provisions of the UN Law of the Sea. Sri Lanka has jurisdiction over an Exclusive Economic Zone (EEZ) which extends 200 nautical miles outwards from the shoreline and covers an area of over 230 000 km2 of the ocean. Along its coast line are a variety of ecosystems which include sandy beaches, rocky shores, lagoons and estuaries, mangrove stands, salt marshes and sand dunes. In the shallow waters off the coastline are found sea grass beds, coral growths and coral reefs. The other coastal ecosystems of significant importance are the mangroves and coastal wetlands. They serve as habitats for a large number of commercially important species, as food producers, run-off retainers, salt traps, water purifiers and as coastal stabilizers. Mangroves are among the few woody plants which can tolerate the undiluted salinity of the open sea. The seas overlying the Continental shelf are referred to as coastal. They support our coastal fisheries, which are the main source of marine fish production. Beyond the edge of the continental shelf is the ‘continental slope’, which descends rather steeply to the floor of the deep ocean. The waters beyond the continental edge form our ‘offshore’ ocean waters.
Marine biological resources include fishery, shrimps, lobster, crash, sea cucumber, economically valuable sea weeds, and a large number of ornamental fish.
International protection
The United Nations Convention on the Law of the Sea was adopted by the third United Nations Conference on the Law of the Sea (UNCLOS III) on April 30, 1982 after lengthy conference negotiations at which 157 Governments took part. On December 10, 1982 the Convention was signed by 119 delegations. The final Convention consisted of a preamble and 445 Articles, divided in to 17 parts and 9 annexes. It can be seen that the Law of the Sea Convention is not restricted to codifying, consolidating and reaffirming the existing international law. In addition, it establishes novel concepts such as the exclusive economic Zone (EEZ), the regime for Archipelagic State and the common heritage of man kind. Article 2 of Part II provides for the breadth of the territorial sea to be up to a limit of 12 nautical miles. Article 46 provided for the establishment of a 200 nautical mile exclusive economic Zone. Article 118 of part II introduced a new concept of Archipelagic baselines, helping to delimit the territorial sea and other zones of Archipelagic States. There are special provisions in Articles 56, 61, 62 and 119 of the UNCLOS III for conservation of the living marine resources. Article 91 of the UNCLOS III is also important concerning the rights and duties of coastal states.
Sri Lanka is a party to the Law of the Sea Convention acceded to by Sri Lanka on December 10, 1982 and exercises jurisdiction over the territorial sea, continental shelf, the exclusive economic zone and the contiguous zone in keeping with the definitions laid down in that convention.
Constitutional protection
Environmental protection has received constitutional recognition in Sri Lanka under 1978 Constitution of Sri Lanka. Chapter VI on Directive Principles of State Policy and Fundamental duties of the 1978 Constitution makes specific reference for promoting environmental well being under Article 27(14). The corresponding duty of a citizen to promote ecological security also finds expression in the Constitution under Article 28. (f)
Under the 13th Amendment enacted in 1987, powers and functions of government are categorized into three lists, namely the Provincial Councils Lists (List 1), the Reserved List (List II), and the Concurrent List (List III). Protection of the environment has been listed as a concurrent subject in List III. This means that Parliament may make laws with respect to the protection of the environment after consultation with all provincial councils, as it seems appropriate. Under List 1, the function of environmental protection within the province is assigned to provincial councils to the extent permitted by or under any law made by the Parliament.
Legislative protection
During the British period in Sri Lanka from 1796 – 1948, they paid some attention to the protection of coastal and marine resources in the country. Accordingly several relevant statutes were enacted. The Crown Lands Ordinance (1947) was enacted amongst other things to provide for the administration and control of inland waters and to define the crown’s rights in what are known as Res Publicae and Res Communes in Roman Dutch Law. The legal position regarding State control over the foreshore must now be ascertained by reference to the Crown Lands Ordinance, the Coast Conservation Act, and other Statutes regulating land use and development.
Since Independence in 1948, successive governments had extensively paid attention towards the protection of coastal and marine resources. National legislation like the Maritime Zones Act No. 22 of 1976, Fisheries and Aquatic Resources Act No. 2 of 1996, Coast Conservation Act No. 57 of 1981, Marine Environment Protection Act 2008 etc., are compatible to a great degree with the international law on the subject introduced by UNCLOS 111.
The Coast Conservation Act also defines foreshore in a slightly modified and specific manner as the ‘area of the shore of the sea between the mean high water and the mean low water mark (Section 42). Nevertheless it does not qualify the provisions of the Crown Lands Ordinance regarding the State’s right to control and manage the seashore and issue permits in respect of it.
It merely affirms that the ‘administration, control, custody and management of the Coastal Zone (a much wider area as defined in section 42 is in the Republic in Sri Lanka’). (Section 2)
The legal position regarding the sea is also a matter for international law. However, today Sri Lankan statutes contain provisions that regulate State rights and interest in respect of the sea. It is useful to briefly refer to the Maritime Zones Law No 22 of 1976 the major legislation that regulates this subject (Sections 11,12) and the Marine Pollution Prevention Act No 59 of 1981. ‘The sea’ for the purposes of our law has been defined by the Marine Pollution Prevention Act as ‘Sri Lankan waters’ (Section 37). This is defined as including specific areas of the sea around the island by the Maritime Zones Law. This law declares the extent of territorial sea and the other maritime Zones of Sri Lanka. It gives President of the Republic the power to declare by the proclamation published in the Gazette the limits of the territorial of sea of Sri Lanka, specifying the base lines from which such limits may be measured. The territorial sea is defined as the sea beyond the land and the internal waters (Section 2 (1)).
The law also provides for a similar declaration of the limits of the contiguous zone, which shall extend seawards from the outer limits of the territorial sea (Section 4). Other areas which can be declared as part of the Sri Lankan waters are ‘the exclusive rconomic zone’, and the pollution prevention zone (an area adjacent to the territorial sea, its sea bed and subsoil.
The Maritime Zones Law vests the State (the Republic of Sri Lanka) with sovereign rights in the territorial sea and its bed and subsoil. (Section 2(3)). This includes the air space above the territorial sea. The State is vested with rights over the all natural resources within exclusive economic zone. It has also exclusive right to control scientific research in this area and in regard to construction, maintenance and operation of scientific devices that are necessary for exploring and exploiting the resources of this zone or for any other purpose. It has the sovereign rights of economic use and the right to explore, exploit conserve and manage the natural resources of this zone (Section 5)2)(3)). Similar rights have been vested in regard to the continental shelf. (Section 6).
The Coast Conservation Act No 57 of 1981 by its Section 2 places the administration, control, custody and management of the coastal zone in the hands of the state. The Coast Conservation Department is the agency with authority over the coastal zone. The coastal zone is the area lying within 300 m landwards of the mean high water line and the area within 2 km seawards of the mean low water line. In the case of water bodies connected to the sea, the landwards boundary extends 2 km from the natural entrance points. (Section 42).
The Coast Conservation Act No 57 of 1981 and its amended Act No. 64 of 1988 prohibits any person to engage in a development activity within the coastal zone, unless such person is authorized by a permit issued by the Director of Coast Conservation. Section 6 of the Act provides for the appointment of a Coast Conservation Advisory Council mandated with advising the Minister of Fisheries on all development activities proposed to be commenced in the coastal zone, reviewing the Coastal Zone Management Plan (CZMP) and forwarding recommendations to the Director/ Coast Conservation.
The Marine Pollution Prevention Authority (MPPA) was established by the Marine Pollution Prevention Act No 59 of 1981. The purpose of this Act is to give effect to the several international conventions of marine pollution and civil and criminal liability to which Sri Lanka has become a signatory. The MPPA has authority over Sri Lanka waters which includes the territorial sea, contiguous zone, the exclusive economic zone, the continental shelf and pollution prevention zone as defined in the Maritime Zones Law No 22 of 1976.
The Marine Pollution Prevention Act No 59 of 1981 gives effect to the following five International Conventions:
1. The International Convention on the Prevention of Pollution of the Sea by Oil 1954, as amended;
2. The International Convention on Civil Liability for Oil Pollution Damage, 1969;
3. The International Convention on the Establishment of an International Fund for Compensation for Oil Pollution Damage 1971;
4.The International Convention relating to Intervention on the High Seas in Case of Oil Pollution Casualties, 1969; and
5. The International Convention for the Prevention of Pollution from Ships, 1972 and the Protocol of 1978.
National Aquatic Research Development Agency (NARA) has been established under the Act No.54 of 1981 for development of marine resources and it handles research and some aspects of development of this subject. This is a comprehensive Act with regard to Fisheries Regulations made in 1941and 1981. National Aqua Culture Development Authority was established under the Act No. 55 of 1998.
Fauna and Flora Protection (Amendment) Act, No 49 of 1993 Provides for six categories of protect areas – among which are a marine sanctuary and natural reserve. Fisheries and Aquatic Resources Act No 2 of 1996 provides for the management and regulation of fisheries and aquatic resources in Sri Lanka and its repeals the Fisheries Ordinance No 24 of 1940, the Chank Fisheries Act No. 08 of 1953, Perl fisheries Ordinance No 2 of 1925 and the Whaling Ordinance of No. 02 of 1936.
The Marine Environment Protection Authority Act of 2008 provides for the prevention, reduction and control of pollution in Sri Lankan territorial sea, coastal areas as well as other sea areas.
The Act established the Marine Environment Protection Authority as a Regulatory body to administer the Act. The Coast Guard Department established under the Coast Guard Act No. 14 of 2009 is to implement the laws of the land and international laws on the territorial waters of Sri Lanka.
Issues and remedies
Toxic materials entering coastal areas and territorial and seas result in coastal erosion and destruction of fish nursery areas. Hence, the global marine environment in the territorial sea is increasingly threatened by inter alia, over fishing, global climate change, habitat modification and destruction of it.
Sea erosion induced by river sand mining, and population pressure resulting from more people finding livelihoods and employment in coastal areas, as well as a booming tourist industry that has exceeded the carrying capacity in several locations causing extensive damage to the critical ecosystems, have led to substantial lowering of the protective and buffering capacity of the habitats of the coastal zone.
The magnitude of devastation resulting from the tsunami that Sri Lanka and several other Indian Ocean countries experienced awakened authorities, civil society, and all other organised groups to the reality of observing the level of unpreparedness, either to face and mitigate such calamities, or manage an expedient recovery plan.
Coral reefs in the territorial sea should be declared as bio reserves and should be further protected. Strict marine resource laws should be enacted by all tropical countries to prohibit coral reef mining for building or other purposes. The territorial sea bed drilling has a harmful impact on territorial sea marine resources. Therefore territorial sea drilling in sensitive coral reef areas has to be totally banned. Oil tanker shipping routes must be specified to avoid coral reef areas and other marine resources in the territorial sea.
The oil spill is very dangerous to living biological marine resources in the territorial sea. Safety standards of ships, vessels seaworthiness and harbour rules and regulations should be introduced under the Shipping Law and heavy penalties have to be imposed on polluting vessels in the territorial sea areas.
At this stage it should also be pointed out that the scope of State’s rights in the Coastal and Marine resources as well as natural resources of Sri Lanka are not absolute rights. In fact, the President of the Republic of Sri Lanka, being the Head of State of Sri Lanka, serves not as an owner but only as a ‘custodian’ of all natural resources of the country inclusive of coastal and marine resources.

Let us protect our biodiversity
On Sunday May 22, the international community marks an important day but unfortunately not many people are aware of its deep significance. The United Nations has proclaimed May 22 as the International Day for Biological Diversity (IDB) to increase understanding and awareness of biodiversity issues. In December 2000, the UN General Assembly adopted May 22 as IDB, to mark the adoption of the text of the Convention held on May 22, 1992 by the Nairobi Final Act of the Conference.
This year’s theme is, ‘Mainstreaming Biodiversity; Sustaining People and their Livelihoods.’ For those who do not know or do not care, Biological diversity or biodiversity is the term given to the variety of life on Earth. It is the variety within and among all species of plants, animals and micro-organisms and the ecosystems within which they live and interact. Biodiversity comprises the millions of different species that live on our planet and the genetic differences within the species. It also refers to the multitude of different ecosystems in which species form unique communities, interacting with one another and the air, water and soil.
Biodiversity is explored at three levels: genetic diversity, species diversity and ecosystem diversity. According to science journals, Human alteration of the global environment has triggered the sixth major extinction event in the history of life and caused widespread changes in the global distribution of organisms. These changes in biodiversity alter ecosystem processes and change the resilience of ecosystems to environmental change. This has profound consequences for services that humans derive from ecosystems. The large ecological and societal consequences of changing biodiversity should be minimized to preserve options for future solutions to global environmental problems.
Humans have extensively altered the global environment, changing global biogeochemical cycles, transforming land and enhancing the mobility of biota. Fossil-fuel combustion and deforestation have increased the concentration of atmospheric carbon dioxide (CO2) by 30% in the past three centuries — with more than half of this increase occurring in the past 50 years. We have more than doubled the concentration of methane and increased concentrations of other gases that contribute to climate warming. In the next century these greenhouse gases are likely to cause the most rapid climate change that the Earth has experienced since the end of the last glaciation 18,000 years ago and perhaps a much longer time. Industrial fixation of nitrogen for fertilizer and other human activities has more than doubled the rates of terrestrial fixation of gaseous nitrogen into biologically available forms. Run off of nutrients from agricultural and urban systems has increased several-fold in the developed river basins of the Earth, causing major ecological changes in estuaries and coastal zones.
The UN in a message to mark this event says Biodiversity is the foundation for life and for the essential services provided by ecosystems. It therefore underpins peoples’ livelihoods and sustainable development in all areas of activity, including economic sectors such as agriculture, forestry, fisheries and tourism, among others. By halting biodiversity loss, we are investing in people, their lives and their well-being.
The thirteenth meeting of the Conference of the Parties to the Convention on Biological Diversity (COP 13) to be held in Cancun, Mexico from December 4 to 17 this year will focus on the mainstreaming of biodiversity within and across sectors. This is closely linked to this year’s IDB theme.
According to the latest figures, Plant diversity and endemism in Sri Lanka are quite high. Of 3,210 flowering plants belonging to 1,052 genera, 916 species and 18 genera are endemic.[3] All but one of Sri Lanka’s more than 55 dipterocarp (Sinhalese “Hora”) are found nowhere else in the world. Sri Lanka’s amphibian diversity is only becoming known now. Sri Lanka may be home to as many as 140 species of amphibians. More than 50 known freshwater crabs are confined to Sri Lanka.
Though most Sri Lankans are not aware of this, the neo-colonial economic power blocks are quite aware. Experts and companies from those countries have been making subtle attempts to exploit Sri Lanka’s rare biodiversity. The national government needs to closely monitor this area and ensure that the full benefits of Sri Lanka’s biodiversity are obtained by our people for the common good of the country – (Source 19 May 2016- Daily Mirror (Sri Lanka): http://www.dailymirror.lk/109718/Let-us-protect-our-biodiversity#sthash.sfnjiZ6n.dpuf)
Canada Wildfires Have Grown 200,000 Acres, Thousands Evacuated
(Photo : Scott Olson/Getty Images)
Canadian wildfires have grown over 200,000 acres and many people have been forced to evacuate.
As the fire grew, many people were forced to go into evacuation. On Thursday, the Alberta government said there were more than 1,100 firefighters, 145 helicopters, 138 pieces of heavy equipment and 22 air tankers were sent to fight a total of 49 wildfires, with seven considered out of control.Currently, Candian officials help 8,000 people to airlift from Fort McMurray. The officials are hoping that the motorway to the south will be become safe by Friday so they can help move the remaining 17,000 people, according to BBC.
Luckily, there were no injured people reported. Is climate change the reason for more wildfires?
There are 1.9 billion hectares of boreal forest around the world, and Canada is home to 552 million hectares or 28 per cent of the world’s boreal zone according to Global News. Boreal forest is the largest terrestial biome, is also known as taiga or snow forest that consist mostly of pines, larches, and spruces. These forests are under threat by a climate change because of continues warming of temperature. Currently, boreal forests have already warmed by 0.5 C to 3 C. The continues rising of temperature linked to drier conditions.
According to the latest report of Intergovernmental Panel on Climate Change (IPCC), the area of boreal forest burned in North America has doubled over the past 20 years.
The three key ingredients to propagate wildfire weather conditions are hot weather, wind , and low humidity. A warming climate may produce two of the three ingredients. It could be warm air, which is usually associated with drier conditions. The wildfire could erupt if there is wind and a forest fire.

Leopards have lost 75% of their historical habitat
New research shows the big cats’ global range has shrunk by a shocking amount over the last 250 years.

The area of the world roamed by leopards has declined by three-quarters over the last two and a half centuries, according to the most comprehensive effort yet to map the big cat.
Researchers said they were shocked by the shrinking of the spotted hunter’s range, and that the decline had been far worse for several of the nine subspecies of leopards and in some parts of the world.
“We found the leopard had lost 75% of its historical habitat, we were blown away by that, it was much more than we feared,” said Andrew Jacobson, a conservationist at the Zoological Society of London and lead author of a new study on their range published in the journal PeerJ.
“Our goal has to be to raise consciousness about the plight of the leopard, it’s been flying under the conservation radar for a while. We hoped to raise its profile and say ‘this cat needs your attention’.”
The new work is the first known attempt to draw up a global, historical map of the leopard. Jacobson and researchers found that in 1750 it occupied a vast 35m sq km (13.5m sq mile) area throughout Africa, the Middle East and Asia. But after centuries of habitat loss and hunting caused by humans, that area shrank to just 8.5m sq km.
Leopards in Asia have been particularly badly hit, with six regions losing over 95% of habitat where the species has been, in Jacobson’s view, “almost completely wiped out”.
There appeared to be a clear link between Asia’s economic development and the leopard’s decline there, he said. “South-east Asia and China have been developed for a long period of time and that’s seriously constricted habitat in that area for decades. We worry this will be the trend we will see in Africa in coming decades, as economies grow.”
Even in Africa, the paper found, losses varied greatly, with their range decreasing 99% in North Africa, up to 95% in West Africa but only up to 51% in Southern Africa.
Leopards are a famously reclusive but adaptable species, living nocturnally and hunting a wider variety of prey than other species. They also appear more capable than other big cats at adapting to environments transformed by humans, with leopards living in the outskirts of Mumbai and Johannesburg.
There are no reliable population estimates but it is thought there are over a 100,000 left in Africa and perhaps fewer than 10,000 in Asia.
Jacobson, who is also part of theNational Geographic Society’s Big Cats Initiative, said it was not too late for leopards to bounce back. “I think the leopard can come back. The leopard is an incredibly adaptable animal, we just need to ease off on the hunting pressure, the persecution. They’re cats, they breed pretty well.”
But greater conservation efforts were needed to stop them suffering the dramatic declines seen by some other species, he said. “When people think of endangered animals they think of tigers, elephants, rhino. Thankfully the leopard isn’t in that category yet, and if we are more proactive about them we can stop them being in there.”
The new study – Leopard (Panthera pardus) status, distribution, and the research efforts across its range – examined 6,000 records at 2,500 locations, from over 1,300 sources, including other scientific literature and experts’ data, to draw up a detailed reconstruction of leopards’ range today and in 1750.
