1.       Tigray region:

Tigray is one of the nine administrative regions of Ethiopia [also known by its official name Federal Democratic Republic of Ethiopia]. It has a total population of 6.2 million people out of which 85% live in the rural areas. The region has about 51.8 % of its total population which are with in the economically active age group. Based on the 2007 census, the region is reported to have an ethnic composition, 94.98% Tigrawai (Tigriyan ethnic group), 2.6% Agew-Amhara, 0.7% Erob and 0.05% Kunama. What is more, Tigrigna, Erobgna, and Kunamgna are the most spoken languages in the region. However, the working language is Tigrigna.

The region has long history, [over 4 thousand year old Axumaite kingdom] civilization and is home to Emperor Yohannes IV and General Alula Abanega patriotic figure in the Ethiopian history. The Axumite kingdom was once very powerful and had tremendous influence around present day Rea sea countries. It left rich architectural and archaeological heritage worth visiting. If you are interested in ancient history and civilization it has a lot to offer and Tigray should be on your priority list.

1.1.  Avifauna of Tigray
The Tigrayan highlands are not very wide, because the Tacazze River, one of the tributaries of the Nile, draining the major part of the Tigrayan highlands, separates them from the Semien Mountains, west of it. Through the river valley and adjacent hills birds typical for the Sudan-Guinea biome can penetrate far into the highlands where they sometimes can be seen alongside birds typical for the Somali-Masai biome, that enter the highlands from the East. For instance White-fronted Black Chats Myrmecocichla albifrons and Chestnut-crowned Sparrow Weavers Plocepasser superciliosus together with Brown-tailed Rock Chats Cercomela scotocerca and Rüppell's Weavers Ploceus galbula. Although there are many more interesting aspects about the savannah birds of these two biomes, for the visitor to Tigray the highlands probably have the most interesting habitats and avifauna.
The avifauna of Ethiopia includes a total of of 924 species, of which 23 are endemic and 3 are rare or accidental. In Tigray(see figure below) the estimated bird specie is more than 500 [more than half of the Ethiopian birds are found in this region]. It is not a coincidence that Tigray is rich in birds. The variety in habitats over a vast altitude range is huge. It extends from 3999 m above sea level [in Tsibet Mountain] to 500 m above sea level in Tekeze valley.  The birds treated here are birds available in Tigray (excepted those highlighted with yellow which are given for sake of comparison)

Some of the common bird   Orders
 1. Podicipediformes:
The order Podicipediformes (Fürbringer, 1888) has 22 species, 6 genera and one family (the Podicipedidae). The family is characterized by slender, pointed bills and lobed feet. They are all called by common name grebes.

Grebes are small to medium-large sized freshwater diving birds with lobed toes. They are an excellent divers and swimers. Due to the position of their feet being placed far back on their body they are quite ungainly on land. Globally about 20 species grebes are known among 3 species occur in Ethiopia.






          Figure 2. Tachybaptus ruficollis                                                            Figure 3. Podiceps cristatus            

Adult Podiceps cristatus is charaterized by black frills on the sides of the head and black tuft on each side of the crow. It is found in fresh water lakes and some of the recently contructed reserviours of tigray.

Adult Tachybaptus ruficollis have chustnut red face and throat.just like Podiceps cristatusit, it occurs in freshwater lakes and dams. but sometimes it is seen in slow flowing rivers  

1.1       Pelicans

Pelicans are characterized by long hook-tiipped bills and with a distinctive pouch under the beak suspended from the mandible and upper part of throat. Like the other members of the order Pelecaniformes, they have webbed feet with four toes. There are 8 species worldwide out of which 2 of these species namely: Pelecanus onocrotalus and Pelecanus rufescens occur in Ethiopia. Taxonomically pelicans are classified into Order: Pelecaniformes. Family: Pelecanidae
  1. Great White Pelican Pelecanus onocrotalus
  2. Pink-backed Pelican Pelecanus rufescens
Adult Pelecanus onocrotalus are completely white with black and grey flight feathers (characyterized as pinkish white). They occur throught Ethiopia and Tigray (see picture below from lake hashengie). The immature Pelecanus onocrotalus dusky white in colour
Pink-backed Pelican adults are pale grey in colour with very well developed (large) crest. During flight their deep vinous-pink rump and back are easy distingushing characteristics

Mother's Love ፍቅሪ ኣዶ የናት ፍቅር


Teacher: Hello every one
Students: Hello teacher
TeacherHow are you doing today?
Students: we are fine thank you teacher
Teacher:  Good! now I am going to share with you about very important issue that you might not have thought of it. 
Some of the students murmured at the back and asked each other wow!! what is it? 
Teacher: silence please , did you ask What is it?  question to yourselves? It is Ok!! 
Here we go I am going to tell about it and share a wonderful thought today. It is just mother’s love. Do you really love your mother? 
Students: Yes we do they answered all out loud
Teacher:  Ok! Ok! No! doubt about it. But how much? That is what matters students.
Students: Alot
Teacher: Fine! different people express their Love to their mothers differently: some of us just gave her a hug, others bought a flower (strange! right?), some others are angry at her (ekk!! nonsense) and few others by writing a letter when they are far away only. While others saying no word to her but burn inside loving their mom (because they are mute to say a word, may be they have no appropriate word to express their love).
Teacher: How do you express your love to your mother? Say it now!!!!!
Here is a Poem by Helen
A Mother's love is something

that no one can explain,

It is made of deep devotion and

and of sacrifice and pain,

It is endless and unselfish

and enduring come what may

For nothing can destroy it

or take that love away . . .

It is patient and forgiving

when all others are forsaking,

And it never fails or falters

even though the heart is breaking . . .

It believes beyond believing

when the world around condemns,

And it glows with all the beauty

of the rarest, brightest gems . . .

It is far beyond defining,

it defies all explanation,

And it still remains a secret

like the mysteries of creation . . .

A many splendour miracle

man cannot understand

And another wondrous evidence

of God's tender guiding hand.

Convention on Biological DiversityConvention on Biological Diversity

Signed by 150 government leaders at the 1992 Rio Earth Summit, the Convention on Biological Diversity is dedicated to promoting sustainable development. Conceived as a practical tool for translating the principles of Agenda 21 into reality, the Convention recognizes that biological diversity is about more than plants, animals and micro organisms and their ecosystems – it is about people and our need for food security, medicines, fresh air and water, shelter, and a clean and healthy environment in which to live.

Introduction

The Convention on Biological Diversity (CBD) entered into force on 29 December 1993. It has 3 main objectives: 
  1. The conservation of biological diversity
  2. The sustainable use of the components of biological diversity
  3. The fair and equitable sharing of the benefits arising out of the utilization of genetic resources

The following links provide detailed information regarding the Convention and how it operates:
How the Convention on Biological Diversity promotes nature and human well-being?

Biodiversity - The Web of Life

Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity we see today is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans. It forms the web of life of which we are an integral part and upon which we so fully depend.
This diversity is often understood in terms of the wide variety of plants, animals and microorganisms. So far, about 1.75 million species have been identified, mostly small creatures such as insects. Scientists reckon that there are actually about 13 million species, though estimates range from three to 100 million.
Biodiversity also includes genetic differences within each species - for example, between varieties of crops and breeds of livestock. Chromosomes, genes, and DNA-the building blocks of life-determine the uniqueness of each individual and each species.
Yet another aspect of biodiversity is the variety of ecosystems such as those that occur in deserts, forests, wetlands, mountains, lakes, rivers, and agricultural landscapes. In each ecosystem, living creatures, including humans, form a community, interacting with one another and with the air, water, and soil around them.
It is the combination of life forms and their interactions with each other and with the rest of the environment that has made Earth a uniquely habitable place for humans. Biodiversity provides a large number of goods and services that sustain our lives.
At the 1992 Earth Summit in Rio de Janeiro, world leaders agreed on a comprehensive strategy for "sustainable development" -- meeting our needs while ensuring that we leave a healthy and viable world for future generations. One of the key agreements adopted at Rio was the Convention on Biological Diversity. This pact among the vast majority of the world's governments sets out commitments for maintaining the world's ecological underpinnings as we go about the business of economic development. The Convention establishes three main goals: the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of the benefits from the use of genetic resources.

Source:http://www.cbd.int/convention
The Convention on Biological Diversity, as an international treaty, identifies a common problem, sets overall goals and policies and general obligations, and organizes technical and financial cooperation. However, the responsibility for achieving its goals rests largely with the countries themselves.
Private companies, landowners, fishermen, and farmers take most of the actions that affect biodiversity. Governments need to provide the critical role of leadership, particularly by setting rules that guide the use of natural resources, and by protecting biodiversity where they have direct control over the land and water. Under the Convention, governments undertake to conserve and sustainably use biodiversity. They are required to develop national biodiversity strategies and action plans, and to integrate these into broader national plans for environment and development. This is particularly important for such sectors as forestry, agriculture, fisheries, energy, transportation and urban planning. Other treaty commitments include:
  • Identifying and monitoring the important components of biological diversity that need to be conserved and used sustainably.
  • Establishing protected areas to conserve biological diversity while promoting environmentally sound development around these areas.
  • Rehabilitating and restoring degraded ecosystems and promoting the recovery of threatened species in collaboration with local residents.
  • Respecting, preserving and maintaining traditional knowledge of the sustainable use of biological diversity with the involvement of indigenous peoples and local communities.
  • Preventing the introduction of, controlling, and eradicating alien species that could threaten ecosystems, habitats or species.
  • Controlling the risks posed by organisms modified by biotechnology.
  • Promoting public participation, particularly when it comes to assessing the environmental impacts of development projects that threaten biological diversity.
  • Educating people and raising awareness about the importance of biological diversity and the need to conserve it.
  • Reporting on how each country is meeting its biodiversity goals.
Surveys
One of the first steps towards a successful national biodiversity strategy is to conduct surveys to find out what biodiversity exists, its value and importance, and what is endangered. On the basis of these survey results, governments can set measurable targets for conservation and sustainable use. National strategies and programmes need to be developed or adapted to meet these targets.
Conservation and sustainable use
The conservation of each country's biological diversity can be achieved in various ways. "In-situ" conservation - the primary means of conservation - focuses on conserving genes, species, and ecosystems in their natural surroundings, for example by establishing protected areas, rehabilitating degraded ecosystems, and adopting legislation to protect threatened species. "Ex-situ" conservation uses zoos, botanical gardens and gene banks to conserve species.
Promoting the sustainable use of biodiversity will be of growing importance for maintaining biodiversity in the years and decades to come. Under the Convention, the "ecosystem approach to the conservation and sustainable use of biodiversity" is being used as a framework for action, in which all the goods and services provided by the biodiversity in ecosystems are considered. The Convention is promoting activities to ensure that everyone benefits from such goods and services in an equitable way.
There are many examples of initiatives to integrate the objectives of conservation and sustainable use:
  • In 1994, Uganda adopted a programme under which protected wildlife areas shared part of their tourism revenues with local people. This approach is now being used in several African countries.
  • In recognition of the environmental services that forests provide to the nation, Costa Rica's 1996 Forestry Law includes provisions to compensate private landowners and forest managers who maintain or increase the area of forest within their properties.
  • In different parts of the world, farmers are raising crops within mixed ecosystems. In Mexico, they are growing "shade coffee," putting coffee trees in a mixed tropical forest rather than in monoculture plantations that reduce biodiversity. These farmers then rely entirely on natural predators common to an intact ecosystem rather than on chemical pesticides.
  • Tourists, attracted in large numbers by the spectacular beauty of marine and coastal diversity of the Soufrière area of St. Lucia, had a negative impact on the age-old and thriving fishing industry. In 1992, several institutions joined with fisherfolk and other groups with an interest in conservation and sustainable management of the resources and, together, established the Soufrière Marine Management Area. Within this framework, problems are dealt with on a participatory basis with the involvement of all stakeholders.
  • Through weekly "farmer field schools," rice farmers in several Asian countries have developed their understanding of the functioning of the tropical rice ecosystem - including the interactions between insect pests of rice, their natural enemies, fish farmed in the rice paddies, and the crop itself - to improve their crop management practices. This way they have increased their crop yields, while at the same time almost eliminating insecticide use with positive benefits in terms of environmental and human health. About 2 million farmers have benefited from this approach.
  • In Tanzania, problems surrounding the sustainable use of Lake Manyara, a large freshwater lake, arose following increased usage in recent decades. The formation of the Lake Manyara Biosphere Reserve to combine both conservation of the Lake and surrounding high value forests with sustainable use of the wetlands area and simple agriculture has brought together key users to set management goals. The Biosphere Reserve has fostered studies for the sustainable management of the wetlands, including monitoring the ground water and the chemistry of the escarpment water source.
  • Clayoquot Sound on the western coast of Vancouver Island, Canada, encompasses forests and marine and coastal systems. The establishment of adaptive management to implement the ecosystem approach at the local level is currently under development with the involvement of indigenous communities, with a view to ensuring rational use of the forest and marine resources.
  • Sian Ka'an Biosphere Reserve in Mexico has great cultural value with its 23 recorded Mayan and other archaeological sites while also being the home of some 800 people, mainly of Mayan descent. The reserve forms part of the extensive barrier reef system along the eastern coastline of Central America and includes coastal dunes, mangroves, marshes and inundated and upland forests. The inclusion of local people in its management helps maintain the balance between pure conservation and the need for sustainable use of resources by the local community.
Reporting
Each government that joins the Convention is to report on what it has done to implement the accord, and how effective this is in meeting the objectives of the Convention. These reports are submitted to the Conference of the Parties (COP) - the governing body that brings together all countries that have ratified the Convention. The reports can be viewed by the citizens of all nations. The Convention secretariat works with national governments to help strengthen reporting and to make the reports of various countries more consistent and comparable, so that the world community can get a clearer picture of the big trends. Part of that work involves developing indicators for measuring trends in biodiversity, particularly the effects of human actions and decisions on the conservation and sustainable use of biodiversity. The national reports, particularly when seen together, are one of the key tools for tracking progress in meeting the Convention's objectives.
