Salinity stress remains one of the world's oldest and the most serious environmental problem, which substantially hampers crop productivity in many arid and semi arid regions. Several reclamation measures like additions of gypsum, sulphur and sulphuric acid to soils, and construction of wells and drainage canals to reduce concentrations of salts in root zones had been advocated and used by many nations. However, these practices were discontinued due to escalating energy costs. The development of salt tolerant crop cultivars presents a possible alternative to expensive engineering approaches...

Wetland ecosystems are interconnected and §interactive within a watershed. In Uchalli Wetlands §Complex the environmental pressure of drought and §growing demand of agriculture has taken its toll of §wetlands. The study revealed about 73% decline in §the water surface area and 90 % in birds population §and loss in the interconnectivity among wetlands §disrupting the drainage network and the hydrological §regime leading to irreversible changes in wetland §quality. Various measures including the creation of §wetlands restoration team is suggested to help §restore the degraded lakes,...

A correlative study was conducted to test the impact of urban congestion on the avian diversity in Lahore, Pakistan. A feeding station, offering a variety of seeds, was installed in the nine towns of Lahore and the number of birds that visited the station was noted in both the monsoon and winter season.Winter showed a significant increase in the abundance of birds in comparison with the monsoon season.Grain preference observed, proved Bajra, Indian Millet and Red Indian Millet were the preferred seeds in all areas while Mustard seeds, Corn and Chick Peas were least preferred. 49 species were...

Over the past two decades, Bangladesh has enjoyed impressive economic growth rates and is now poised to become an upper Middle Income Country. Over the same period, the country has made considerable progress in reducing official poverty levels and in meeting its MDG targets. Despite this success, Bangladesh still has a sizeable proportion of its population living in poverty or extreme poverty; and it continues to see levels of inequality steadily rising. Furthermore, Bangladesh remains one of the most climate-vulnerable countries in the world, with millions living in low-lying areas at risk...
