Water Crisis and Water Management in Pakistan 1- Introduction Water plays a vital role in a country’s economy. Water has been critical to the making of human history. The earliest agricultural communities emerged where crops could be cultivated with dependable rainfall and perennial rivers. Simple irrigation canals permitted greater crop production and longer growing seasons in dry areas. Some of the problems faced by the world population are as below. • More than a billion people lack access

and congestion ➢ Soil contamination includes surface runoff‚ leakage into groundwater‚ liquid spills‚ wastewater discharge and littering. If toxins are spilled on the ground or if an underground storage tank leaks‚ soil can become contaminated. Well known contaminants include herbicides and pesticides. ➢ Water pollution is the contamination of water bodies such as lakes‚ rivers‚ oceans‚ and groundwater by human activities. It occurs when pollutants are discharged directly or indirectly

DEFORESTATION INTRODUCTION: Deforestation refers to the cutting‚ clearing‚ and removal of rainforest or related ecosystems into less bio-diverse ecosystems such as pasture‚ cropland‚ or plantations. Examples of deforestation include conversion of forestland to farms‚ ranches‚ or urban use. Thus‚ deforestation is an important issue to be discussed. It has adverse effects on each living beings’ life. Deforestation has become a huge concern in today’s life as there has been a rise in the decline

The water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor

definition of the issue - what is it Land management is the process of managing the use and development of land resources. Over the past few two centuries of exploitation on our land resources‚ has taken a heavy toll on our soils. What are the causes of this issue? e.g land degradation‚ salinity and overgrazing Firstly‚ land degradation is any change in the land that reduces its existing or potential productivity. It commonly occurs wherever the natural balance in the landscape is changed by

ABSTRACT This paper discusses the implications of the water policies on agriculture in Africa. Water Policies play various roles in African agriculture to ensure food and nutrition security and environmental sustainability. The main challenge being faced by the continent is that there are no clear policies that guide the distribution of water scarcity for food production. The objectives of the paper were to examine the extent to which water policies affect African agriculture and highlight

FOUNDATION is the lowest supporting layer of a structure. * Purpose: Transfer the building load to the soil. * The size of the foundation is determined by the weight of the building and the load bearing capabilities of the soil. * When the load bearing capabilities of the soil is low‚ a footing is usually used. Types of Foundation 1. Shallows Foundations * Shallow foundations are those founded near to the finished ground surface; generally where the founding depth (Df) is less than

Further into his research‚ Loris found that “Studies by the Environmental Protection Agency (EPA)‚ the Groundwater Protection Council‚ and independent agencies have found no evidence of groundwater contamination”(Loris). So contrary to popular belief‚ there are actually no studies that prove that fracking contributes to any form of water contamination. And while it is believed that the chemicals used
