Water Drainage Techniques

...and maintenance Under ordinary conditions rain water seeps into the ground and forms underground water. Most of the water that falls as rain soaks into the ground or gets carried away by rivers. But in urban areas, the built environment alters the natural drainage of water, with hard surfaces increasing both the rate and amount of rainwater that turns into run-off. And it has to go somewhere. Traditional piped ‘drains’ have a limited capacity to cope with the high levels of surface water generated by extreme rainfall events. And, when the capacity of one or more parts of the drainage system is exceeded, the worst happens. For example, in the floods of June 2007, extreme rainfall in the Midlands and the north of England led to large-scale urban flooding, with over 55,000 properties affected: two thirds of these were from surface water run-off overloading drainage systems. In addition to flood risk, large amounts of surface water run-off can cause water quality problems. As water runs over hard urban surfaces, it picks up pollutants that are washed into water courses. For example, run-off from roads contains heavy metals and hydrocarbons which can seriously impact on water quality. A well planned drainage infrastructure helps to manage water run-off by preventing domestic properties and other spaces such as paved public areas, car-parks, driveways and roads acting as conduits for run-off water. And it is more sustainable to manage storm water in...

Multiple Use Systems

...Multiple Use Systems Louise Whiting, FAO Introduction Historically people, communities, and water managers have been using man-made delivery systems or natural water systems deliberately for more than a single use. In many rural and urban areas, domestic water networks are used for small-scale productive activities. Similarly, irrigation systems are often de facto providing large amounts of water within their command areas that facilitate access to water for many other uses through recharge of surface streams and groundwater. Lastly aquatic systems (wetlands including rice-based systems) provide many critical productive and ecosystem services to nearby populations (World Water Council, 2009). A recent analysis of large irrigation systems has shown that the vast majority (more than 90%) of irrigation schemes are being used for a range of uses that go well beyond the production of crops for which they were designed (Renault, 2008). Fortunately, a multiple-use services (MUS) concept continues to emerge as an increasingly effective alternative approach to providing water services for the full range of uses, aiming to meet people’s multiple water needs in an integrated manner. MUS can be understood as a participatory, integrated and poverty-reduction focused approach in poor rural and peri-urban areas, which takes people’s multiple water needs as a starting point for providing integrated services, moving beyond the conventional sectoral barriers of the domestic and productive...

ABSTRACT This study compared resource allocation, yield, net farm income and resource use efficiency under private and government controlled vegetable irrigation schemes. Production data covering three vegetable enterprises were collected from 280 respondents. This consisted of 141 from private and 139 from government irrigation schemes, in the Kwanar-Are irrigation areas of Katsina State, Nigeria. Descriptive and econometric analyses were used to analyze the sample data. Our results indicated that though more purchased inputs are allocated in government scheme, the private scheme was more efficient in terms of resource use. Average net farm incomes per hectare were N373,040, N427,070 and N285,975 for pepper, tomato and onion enterprises respectively under the private irrigation schemes. They were N210,045, N325,891 and N244,748 for pepper, tomato and onion enterprises respectively in the government irrigation schemes. Similarly, average returns on naira investment were higher under the private irrigation scheme.

Agricultural Adaptation Strategies to Climate Change Impacts

...is expected to intensify existing problems and create new combinations of risks, particularly in Africa. The situation is made worst due to factors such as widespread poverty, overdependence on rainfed agriculture, inequitable land distribution, limited access to capital and technology, inadequate public infrastructure such as roads, long term weather forecasts and inadequate research and extension. By lessening the severity of key damages to the agricultural sector, adaptation is the key defensive measure. Adaptation to climate change involves changes in agricultural management practices in response to changes in climate conditions. This paper reviews agricultural adaptation strategies employed by farmers in various countries in Africa in cushioning the effects of climate change. The common agricultural adaptation strategies used by farmers were the use of drought resistant varieties of crops, crop diversification, change in cropping pattern and calendar of planting, conserving soil moisture through appropriate tillage methods, improving irrigation efficiency and afforestation and agro-forestry. The paper concluded that improving and strengthening human capital through training, outreach programmes, extension services at all levels may improve capacity to adapt to climate change impact.

Resilience

...or systems to adapt to adverse, stressful or tragic situations. For there to be growth there needs to be resilience so in a sense resilience does not mean a positive outcome but it can also lead to a negative one. According to Browning and Johnson (2010) there is a possibility that the definition of resilience has been misunderstood creating an impression of resilience and recovery being the same. This paper aims at expounding on resilience and its components and how it applies to everyday running of life and other systems that relate to life especially in India. There are many researchers that have come up with different components of resilience depending on where it is to be applied but in this paper there are five components that have applied in a general context. The application of these components will determine if the result of resilience will be positive or negative. This paper will discuss redundancy, diversification, network connectivity, feedback and recovery and how they have been practically applied to various places to build resilience especially in India and Punjab, Pakistan. It will further discuss two other components of resilience that is strongly related to the named components. Finally it will conclude on the basis of choosing the components and the importance of those components. Application of the components of resilience There are many systems that interact in their functioning. The world functions due to interactions such as humans and the eco-system and...

Waste Water Management

...Module 3 Case December 22, 2010 Professor Dr. Nathaniel Ofoe With the United States growing and cities becoming larger and larger day by day, communities have been battling water shortages all throughout the country. For the past fifty or so years reclaimed water has been used all over the world. Within the course of this case paper I will attempt to compare and contrast the secondary water treatment methods to that of the tertiary water treatment methods. Wastewater treatment is classified as primary, secondary, and tertiary treatment; this is the process of how wastewater actually becomes recycled water. The primary treatment process is the initial stage or in other words the beginning of how organic and inorganic solids are removed via sedimentation and flotation. During this initial stage approximately 40-60% of suspended solids and raw sewage are collected in sedimentation tanks and 25-35% of the biochemical oxygen demand (BOD) is removed from the waste stream. During the secondary treatment the out flowing from the primary treatment process contains residual organic and inorganic material. Secondary treatment systems will remove between 80-95% of suspended solids and (BOD) through two methods known as attached growth and suspended growth. Finally we are at the tertiary treatment process also known as the polishing process where treated water is filtered through fine sand or other granular material to remove solids. After the filtering process...

Indus River

...The Indus River Basin: The Continuing Water Disputes Between India and Pakistan Anise Ko August 7, 2014 Professor Beth Bennett Introduction The Indus River was a key factor in the development of the Asian civilization. It originates in the Tibetan plateau and flows through four different countries: Tibet, Afghanistan, India and Pakistan to end in the Arabian Sea. The Indus River catchment area is as follows: sixty percent of the area belongs to Pakistan, about twenty percent belongs to India, five percent belongs to Afghanistan and fifteen per cent belongs to Tibet (Aljazeera, 2011). There are a total of six main tributaries: Sutlej, Ravi and Beas flow through Punjab and the other three rivers of the Indus basin - Indus, Jhelum and Chenab run through the territory of Jammu and Kashmir (Harvard, 2011). Since the partition of the British Indian empire in 1947, Pakistan and India have fought over the province of Punjab and the state of Kashmir, which resulted in a partition of the area between the two countries. The water dispute is also closely related to partition of the Kashmir region, too. The six rivers run through India which controls Jammu and Kashmir, before reaching Pakistan and the part of Jammu and Kashmir governed by Pakistan (Harvard, 2011). The geological allocation described above brought out significant disadvantages to Pakistan in early the1950s as a consequence of the political conflicts between the two countries. The help of the World Bank together with...

Water Resource Management Case Study

...India’s first National Action Plan on Climate Change (NAPCC) outlining present and future policies and programs addressing climate mitigation and adaptation strategies. The plan identifies eight core “national missions” running through 2017, out of which National Water Mission is one of them. Emphasizing the overriding priority of maintaining high economic growth rates in order to raise living standards, the plan “identifies measures that promote our development objectives at the same time yielding co-benefits for addressing climate change effectively.” With water scarcity projected to worsen as a result of climate change, the plan sets a goal of a 20% improvement in water use efficiency through pricing and other measures. The following paper briefly discusses the mission, goals, strategies, implementation framework. It aims to evaluate the performance of the mission with the help of stakeholder analysis. INTRODUCTION India is faced with the challenge of sustaining its rapid economic growth while dealing with the global threat of climate change. This threat emanates from accumulated greenhouse gas emissions in the atmosphere, generated because of long term anthropogenic interventions and intensive industrial growth and high consumption driven lifestyles in developed countries. While engaged with the international community to collectively and cooperatively deal with this threat, India needs a national strategy to firstly, adapt to climate change and secondly, to further enhance...
