A savanna, or savannah, is a grasslandecosystem characterized by the trees being sufficiently small or widely spaced so that thecanopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of C4grasses.[1] Some classification systems[which?] also recognize a grassland savanna from which trees are absent.[2] This article deals only with savanna under the common definition of a grassy woodland with a significant woody plant component.
It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forest. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season. Savannas are associated with several types of biomes. Savannas are frequently in a transitional zone betweenforest and desert or prairie. Savanna covers approximately 20% of the Earth's land area. The largest area of savanna is in Africa.
Pastoralists are people who depend for their living primarily on livestock. They inhabit those parts of the world where the potential for crop cultivation is limited due to lack of rainfall, steep terrain or extreme temperatures. In order to optimally exploit the meager and seasonally variable resources of their environment and to provide food and water for their animals, many pastoralists are nomadic or semi-nomadic.
The type of livestock pastoralists keep varies according to area, and includes sheep, goats, cattle and camels, but also yaks and horses in Central Asia, buffalo in South Asia, llamas and alpacas in South America, and reindeer in the Palearctic region. An important characteristic of pastoralists is their close relationship with their animals. The identity of pastoralists is based on the close association with their livestock that forms a key component of their social and ritual life. By keeping animals under conditions that are close to the wild, but giving them the benefit of protection and health care, pastoralists represent a cultural counterpoint to industrialized animal production in the west.
There is no reliable information available on the number of pastoralists worldwide. According to one estimate, there are around 17.3 million pastoralists in Africa, 3.4 million in the Middle East and South Asia and no more than 2 million in Central Asia (Sandford, 1983).
Pakistan has highest deforestation rate in Asia COMMEMORATED every year on June 5, since 1972, the World Environment Day is a principal vehicle through which the awareness of the environment is stimulated across the world.
It was started by the United Nations General Assembly in 1972 and is hosted every year by different countries with a different theme. It was the first occasion on which the political, social and economic problems of the global environment were discussed at an intergovernmental forum with a view to actually taking corrective action.
The World Environment Day is an opportunity for us all to be involved in something which is critical for our shared future and work in a coordinated manner to empower us all to play an active role in protecting our environment.
The theme of the World Environment Day 2011, in support of the UN International Year of Forests (IYF), is “Forests: Nature at Your Service” a theme that encompasses the issues of deforestation and need to protect green spaces. It also underscores the variety of life-sustaining services that forests provide and calls for action to protect these resources and move towards a green economy.
The environment day is observed every year to highlight troubles and issues pertaining the environment, and how issues like poverty, economy and health are essentially linked to environmental degradation. This year’s theme, forests, harbours the world’s most precious natural resources and communities. These resources are utilised in food, agriculture, medicine, clothing and much more, hence making them a critically important link in the environmental chain.
Pakistan has only 2.5 percent of forest cover with an alarming rate of deforestation. The annual rate of deforestation in Pakistan is -2.1 percent, no Asian country has a forest degradation rate higher than this.
The largest conversions of forest land have taken place in Punjab and Sindh, corresponding to 99,711 acres and 27,874 acres respectively and this is distressing as the government continues with deforestation.
Forests are important in the fight against greenhouse gasses which are impacting climate change. They absorb water and ensure that it is filtered, sustained, and gradually available for consumption. Their degradation does not only impact forest cover ratio of a country, it also leads to real life problems such as soil erosion, damaged watershed areas, leading to pollution in water bodies and endangering water availability in the long term.
A senior lawyer and president of ECO Green Society, Akhtar H Awan, said that he believed that environmental development was one of the key pillars that would achieve sustainability for future generations. He said that the need of the hour was to formulate policies and strategies aiming at sustainable forestry development by adopting holistic and integrated approach to manage forests’ resources.
Forests cover one third of the earth’s land mass, performing vital functions and services around the world which make our planet alive with possibilities. In fact, 1.6 billion people depend on forests for their livelihoods.
Pakistan being in a region of mountains and glaciatic landscape is more susceptible to climatic changes, obvious examples regarding the fact are the intermittent flash floods and harsh weather conditions, to which forests are the keys to cope with these issues.

Humayun in exile.
·The Mughal domain came under the control of one of those nobles, Farid Khan Suri, who assumed the regional name of Sher Shah Suri. Humayun would spend the next 15 years in exile in Sind, Iran, and then Afghanistan.
·During this exile, Humayun's Persian wife, Hamida Begum, a native of Turbat-I Shaykh Jam in Khurasan, gave birth to the future emperor Akbar.
·After Sher Shah's death on 1545 AD, the kingdom survived for about nine years in the hands of his son, Islam Shah. But Islam Shah's unconciliatory nature alienated many Afghan chieftains.
·Eventually, the squabbling for succession among Sher Shah's followers allowed Humayun and the Mughals to return to power in 1555 Iran's Shah Tahmasb (1524-76) had provided Humayun with the necessary troops to recapture Kandahar and then Kabul. Unfortunately, less than a year after regaining power, Humayun died unexpectedly at the age of 48 when he fell down the steps of his library with a handful of books while in his haste to obey the muezzin’s call to prayer on 27 January 1556.
