Participatory Irrigation Management and its Financial Viability: A Case Study

Water is a key input of agriculture. In the past, the area under cultivation was small and there was less stress on farmers to grow more and more of each crop. Water was considered a free good. The situation has changed since. The increase in cropping intensity has led to a rise in the demand for irrigation water. Water is not a free good any more. The provision of irrigation water to the farmer’s fields is going to be costlier. The Government of Pakistan is spending heavily on the operation and maintenance of the irrigation system yet shortage of funds is a major reason for deferred maintenance, which threatens the operational integrity of the irrigation system [World Bank (1988) and Haq (1995)]. The shortfall in O&M funding was estimated to be more than 24 percent in 1993 [World Bank (1994)]. As poor O&M has direct effect on the productivity of agriculture, indirectly it affects the whole economy [Carruthers (1981)]. The allocation of funds for the increasing O&M costs is becoming a problem for the Government of Pakistan with every successive year. One logical answer to this problem is to increase abiana1 fees from the users of irrigation water supplies. The revenue collected through abiana may be used for O&M purposes, but it has been reported that the revenue collection is far less than the expenditures incurred. Resultantly the gap has been increasing every year [Chaudhry (1989)]. This situation demands investigation of abiana recovery and increasing O&M costs to know the real situation which in turn will help in deciding whether it is feasible to divert the financing of O&M activities towards farmer organisations (completely or partially). This paper aims at estimating the present level of operation and maintenance expenditures of the H-4-R Distributary and the present situation of the abiana collection and the extent of its leakage through different means.

Distributed and Load-Adaptive Self Configuration in Sensor Networks

Proactive self-configuration is crucial for MANETs such as sensor networks, as these are often deployed in hostile environments and are ad hoc in nature. The dynamic architecture of the network is monitored by exchanging so-called Network State Beacons (NSBs) between key network nodes. The Beacon Exchange rate and the network state define both the time and nature of a proactive action to combat network performance degradation at a time of crisis. It is thus essential to optimize these parameters for the dynamic load profile of the network. This paper presents a novel distributed adaptive optimization Beacon Exchange selection model which considers distributed network load for energy efficient monitoring and proactive reconfiguration of the network. The results show an improvement of 70% in throughput, while maintaining a guaranteed quality-of- service for a small control-traffic overhead

Dynamic symmetrical topology models for pervasive sensor networks

The success of pervasive computing environments using ubiquitous loco-dynamic sensing devices is very dependent upon the sensor deployment topology (DT) employed. This paper presents a systematic mathematical model for efficient sensor deployment and provides a comparison with other popular topologies. The model focuses upon blanket coverage of a surveillance area using a minimum number of sensing devices, with minimal infra-sensor overlapping to reduce collisions and co-existence problems. Simulation results are presented for the hexagonal, triangular and square grid topologies for various dimensions of surveillance area. The results confirm that the hexagonal model gives optimal performance in terms of requiring the minimal number of sensors. The paper also highlights the improved performance of ubiquitous wireless sensor networks when a hexagonal topology (HT) is used

A Reverse transcription-polymerase chain reaction (RT-PCR) based detection of foot and mouth disease in District Faisalabad, Pakistan during the Year 2016

Foot and mouth disease is an economically devastating disease of livestock that mainly effect cloven-hoofed animals i.e. sheep, goat, cattle, pig, buffalo, deer etc. The aim of this study was to determine the serotypes circulating in the region during 2016. Sampling was done from different outbreaks initially on the basis of clinical signs and later reverse transcriptase-polymerase chain reaction (RT-PCR) was employed for the confirmation of FMDV genome. Out of total 72 samples, 65 were found positive which were then serotyped into type O (n=30), Asia1 (n=19) and A (n=5). Some samples (n=5) were found positive for more than one serotype that were subjected to reverse transcriptase loop-mediated isothermal amplification assay (RT-LAMP) for serotype determination

Poverty in Pakistan: trends and issues

In Jehangir, Waqar A.; Hussain, Intizar (Eds.). Poverty reduction through improved agricultural water management. Proceedings of the Workshop on Pro-poor Intervention Strategies in Irrigated Agriculture in Asia, Islamabad, Pakistan, 23-24 April 2003. Lahore, Pakistan: International Water Management Institute (IWMI).The phenomenon of poverty is receiving the increasing attention of policy makers and institutions with an attempt to improve the living standards of the third world countries. Pakistan is no exemption to that. As the majority of third world population is concentrated in rural areas and dependent on agriculture sector for income, it becomes of special interest to dig into the root causes of poverty in these areas. A number of studies have shown that poverty is concentrated in the rural areas of Pakistan. However, a wide variation in estimates of poverty was experienced owing to various approaches and different poverty lines used by the researchers in estimating the incidence, depth, and severity of poverty. Recently, the Government of Pakistan addressed this issue by circulating the official poverty line. Poverty being a complex phenomenon, its determinants vary from time to time and across different areas. However, most of the studies indicate that poverty in Pakistan is concentrated in rural areas of Pakistan. Applying dollar a day poverty line shows that the poverty in Pakistan is higher as compared with many other Asian countries

Online Load Balancing for Energy-Aware Anycast Routing

Anycast routing offers a flexible paradigm for resource constrained, ad hoc sensor networks, where sensors can route data to any available server. The selection policy of servers in an anycast scenario could assist in keeping the network operating quiescently for a required time frame. This paper proposes a novel load balancing model to make anycast routing decisions based on route efficiency, and remaining life-times of the servers. The model makes use of the historical load and channel capacity profiles to accurately estimate the remaining life of each server. The results show that the proposed technique achieves effective reconfiguration performance to meet the network time-to-live requirement and also maintains better load-balance with anycast routing protoco

HUSEC: A heuristic self configuration model for wireless sensor networks

The Network State Beacons (NSB) exchange rate is the critical parameter in monitoring the dynamic state of any self-configuring ad hoc sensor network. Along with the network state and the overhead control traffic, it determines both the time and nature of any proactive reconfiguration activity that is necessary to counteract any degradation in network performance. While traditionally selected at random, this rate of beacon exchange significantly affects the accuracy with which the variations in network state are tracked. It is therefore imperative to adapt this rate to the variation in load profile and attempt to maintain its value within predefined bounds which can be optimised to keep the network operating quiescently, while conforming to its various Quality-of-Service (QoS) requirements. This paper presents a novel, heuristic self-configuration (HUSEC) model which addresses this optimisation problem. The simulation results confirm that the model reconfigures the network more effectively to not only achieve higher throughput, but also greater network integrity, with minimal control traffic and resource overheads
