Asian farmers sucking the continent dry
Nobody seems to have done anything about this. This is a timebomb. If it is not prevented there will be mayhem.
"The numbers of tubewells have increased from 2700 in 1950 to over 600 000 in the year
2003. The number of users are over 2.5 million farmers, who exploit groundwater through their own tubewells or
hire from their neighbors. Patterns of use are highly variable and there is little understanding about any adverse
interaction, which is likely to result due to the unsystematic and erratic nature of groundwater exploitation."
"Because of the absence of groundwater management in the private sector, anyone can install a tubewell
anywhere in his land and can extract whatever amount of water he wants any time without consideration of the
detrimental effect of his action on the resource."
"tubewells has started showing stress on the aquifer in the form of excessive draw-down and deterioration of groundwater quality. This requires serious attention and the urgent adoption of measures for proper groundwater management.
A groundwater regulatory framework should be introduced and implemented for the sustainability of
groundwater use. Recharge of groundwater should be increased by increasing canal diversions, rainwater
harvesting and check dams.
In Pakistan, the irrigation system was designed for very low cropping intensities, but with population pressure,
the design capacity is unable to cope with the actual cropping intensities. The difference between crop water
requirements and canal supplies is met through exploitation of groundwater. The watertable data of the last 15
years indicates that in 43 canal commands the watertable is depleting."

PAKISTAN’S GROUNDWATER RESERVOIR AND ITS SUSTAINABILITY
Here's Daily Times on ongoing hydroelectric dams and irrigation canals construction in Pakistan:
The prime minister said that the timely completion of hydropower projects was vital for controlling floods along with mitigating water and power shortfall. The government is prioritising the water storage projects, he added.
Raja directed the WAPDA chairman to expedite the work on Kachhi canal, Rainee canal, RBOD-1 and RBOD-III. These projects would be instrumental in controlling the floods as well as for irrigation purposes, he added.
The chairman apprised the prime minister about the progress on eight ongoing projects with cumulative capacity of about 1,500 megawatts (MW).
Out of these, six projects of about 400 MW including Jinnah Dam 96 MW, Gomal Zam Dam 17MW, Satpara Dam 17 MW, Allai Khwar 121 MW, Duber Khwar 130 MW and Jabban Dam 22 MW would be completed in 2012 while the work on Neelum-Jhelum with production capacity of 969 MW and Golen Gol with capacity of 106 MW was progressing at full swing, said the chairman.
The prime minister directed the chairman to take up work on small and medium-sized dams especially in Balochistan and FATA on priority. The prime minister also directed WAPDA chairman to work on war footing to repair the breaches in the canal networks affected by recent floods in Sindh and Balochistan, so that the infrastructure could be restored.

Here's a Dawn Op Ed by Pak hydrologist Dr. Hasan Abbas:
...Do we produce enough electric power in Pakistan? No. Do we have enough water storage capacity? Well, it depends on 1) how we define ‘enough’; and 2) ‘where’ we want to store. Of all the available water in the Indus basin of Pakistan, approximately 95 per cent is directed to agriculture of which over 70 per cent goes waste; less than 30 per cent of it is the actual requirement for the crops we grow.
---
We can build a new dam to store water, or we can use an available storage space in the form of natural ‘aquifers’. Current knowledge of hydrogeology tells us that water storage is carried out better in aquifers than in dams.
If only we refill the depleted aquifers under the city of Lahore, we can store more water than the Tarbela reservoir — that too with the least social and environmental impact.
Rachna, Thal and Bari Doabs all offer excellent aquifers which could be exploited for storage, offering a potential storage capacity hundreds of times more than that of Tarbela, Mangla and Kalabagh combined. Although refilling an aquifer would be expensive, it would be much cheaper than building a large dam.
What about power? Do we need a dam for it? Let’s do some simple math here: the dam building might cost $10 billion with an estimated generation capacity of 5GW. This power, however, enters the grid only after completion of the dam which might take, say, 15 years.
With the prevailing technology of solar power, it costs approximately 90 cents to produce one watt. Given $10bn, we produce 10GW and production can start within the first few months of the project, progressively reaching 10GW in, say, two years.
So what is better — $10bn for 10GW in two years or $10bn for 5GW after 15 years plus the huge social and environmental impact?

The donor countries also share part of the project proportionate to their share of ‘donation’, thus creating jobs and businesses for their own citizens involved in that project. With this, their ‘donated’ capital comes back to re-circulate within their own economies, while the economy of the country being ‘helped’ hardly benefits.
Till the project is complete, the host country accumulates a huge debt, plus interest, without having earned anything. As soon as the project starts delivering, the host country is obliged to meet the loan repayment schedule.
The lending agencies yet again dictate the price of economic goods delivered by the project to match the repayment instalments. The host government returns the loan with interest by making its citizens pay a higher price (than the actual production cost) over a period of 30 years or so.
By the time loans are paid back the project has already lived its useful life and is in a state requiring major overhauls. For example, the lake behind a dam is silted and the power-generating infrastructure is in need of critical repairs and replacements.
This is usually the time when teams of ‘experts’ on behalf of the lending agencies start appearing on the scene yet again, ‘advising and warning’ the host government on the ‘next mega project’ which is deemed ‘absolutely necessary’ to fix the ‘critical’ problems they have identified, or else face doom.
Poor countries like us end up ‘raising the dykes of Mangla dam’ and then keep paying for the facility which they thought they had already paid for. Now we know who are the ‘experts’, where they come from, and why they ‘care’.

Building a large dam for water management and electricity generation is an expensive, unsustainable and outdated idea. Today’s knowledge offers far more economical and sustainable solutions. We must get our investment priorities right — using vision, foresight and the latest knowledge at hand.
Here's a Hydroworld report on Korean investment in Pak hydro sector:
LAHORE, Dec. 26 -- To harness water resources for electricity generation, two memoranda of understanding (MOU) have been signed by the government of Khyber Pakhtunkhwa, the Pakistan Water and Power Development Authority (Wapda) and Korean firms. The agreement involves developing two hydropower projects in a public private partnership with a cumulative power generation capacity of 1,161 MW. According to an announcement made here on Monday, this agreement emerged from President Zardari's recent visit to Korea.
The first MoU was signed with Korea Midland Power Company (KOMIPO) for the 496 MW-Lower Spat Gah Hydropower Project and the second with K-Water/Daewoo consortium for the 665 MW-Lower Palas Valley Hydropower Project. The MoU was signed by Wapda Chairman Raghib Shah, KPK Shydo Managing Director Bahadur Shah, KOMIPO Chairman and CEO Choi Rak and K-Water representative in Pakistan, No Hyuk Park.
Korean Ambassador to Pakistan, Choong Joo Choi, was also present. Addressing the ceremony, he termed the signing of the MoU a milestone that would bring the two countries closer.
Shah said that the Korean firms, which were selected through international competitive biddings, will bring in with them an investment of more than two billion dollars for the construction of the two hydropower projects. This shows the confidence that international financial institutions have in Wapda for the implementation of projects in the water and hydropower sectors, he added.
Shah further said that the two projects will contribute more than 4.5 billion units of electricity to the National Grid annually. He said that they are part of the strategy for optimum utilisation of the water resources to help overcome electricity shortages and stabilise power tariff for the consumers. He said that Wapda is implementing more than 20 projects to generate roughly 20,000 MW of electricity and store 12 million acre feet of water.
Lower Spat Gah Hydropower Project is located on a left bank tributary of River Indus with its confluence some eight kilometers downstream of Dasu town in district Kohistan. Moreover, Lower Palas Valley Hydropower Project is located on another left bank tributary of River Indus with its confluence some 12 kilometers upstream of Patan town in Kohistan district

Here's PakTribune on reduced hydel power in winter causing increased load shedding:
The current wave of load-shedding will end soon, as water flow in canals will come to normal levels in coming days and production of electricity will increase. The government is making all-out efforts to cope with the current situation and eliminate load-shedding.
The energy mix of the country consists of around 34% electricity generation from hydel resources and 66% from oil and gas. Reports show that hydropower production has dropped from 6,500 megawatts to 1,500MW these days.
Every year, canals are closed in winter for de-silting and the Indus River System Authority (Irsa) curtails water releases from major reservoirs of Mangla and Tarbela during December and January, leading to a sharp decline in hydropower production.
On the other hand, gas companies also cut supply in winter to those power producers, which have nine-month gas supply agreements, disrupting electricity production. Thus, the shortfall increases and the Ministry of Water and Power is left with no choice but to opt for power outages.
However, considering the scale of gas and water curtailment, the power supply has been managed very well. The ministry is mindful of providing maximum relief to people by resorting to load-shedding mostly during night and very less power cuts in day time so that routine life of people is not disturbed.
The canals are expected to be opened in the second week of January and production of hydropower will increase and outages will come down.
The ministry is also making alternative plans to cope with the power crisis as it is working to increase the generation capacity of existing power plants.
It is very important that the people should also come forward and help the government in conserving electricity, which could be done by saving power through all possible ways. This way, they will not only be helping the government, but will also reduce their electricity bills....

Here's news on hydroelectric dam projects in FATA:
ISLAMABAD: The Water and Power Development Authority (Wapda) iss working on a number of large and medium-sized dams in the federally administered tribal areas (Fata) including the Gomal Zam Dam in South Waziristan and the project was likely to be completed by end of January.
Official sources told APP here on Thursday that the hydropower component of the dam had already been completed, while progress on the irrigation and flood protection component of the project was almost near completion.
Gomal Zam Dam is being constructed in the Khjori Kach area of South Waziristan, over the Gomal River which iss also one of the significant tributaries of Indus River. The dam will irrigate 163,086 acres of barren land of Tank and districts of Dera Ismail Khan.
The dam will have a gross live storage of water of 1.14 million acre feet (MAF), whereas 0.36 MAF of perennial and flood flow of the Gomal River will provide irrigation water to barren lands.
A small power plant was installed at the foot of the dam. Designed by an Italian company, the plant will produce 17.4 megawatts of power.
The multipurpose project will boost development in the remote area by enhancing irrigation, controlling flash floods and producing economical electricity. The dam was initially conceived in the late 1800s for meeting the water needs of Dera Ismail Khan.

LAHORE: Work on Kurram Tangi Dam, a multi-purpose project in North Waziristan Agency, is set to kick off in the next two months, with the Water and Power Development Authority (Wapda) needing swift handover of land and effective security arrangements.
Briefing Khyber-Pakhtunkhwa Governor Barrister Masood Kausar, Wapda Chairman Syed Raghib Shah revealed that the project had been divided into three components for effective implementation.
Construction work on the first component will be initiated in March this year. In this phase, a weir, two canals covering an area of more than 16,000 acres, two power houses of about 19 megawatts and a 132-kilovolt transmission line will be constructed. Annual benefits of the first component have been estimated at about Rs1.7 billion.
Shah asked the governor to help in early handover of land to Wapda and ensure effective security arrangements.
He said the United States Agency for International Development (USAID) had expressed interest in providing funds for the first component. An environment assessment study is also underway to pave the way for the financing....

Here's a report on Pakistan climate change policy:
Disaster-prone Pakistan has launched its first ever national policy on climate change, detailing how it plans to tackle the challenges posed by global warming, mitigate its risks and adapt key sectors of the country's economy to cope with its consequences.
Pakistan is highly vulnerable to weather-related disasters such as cyclones, droughts, floods, landslides and avalanches. Devastating floods in 2010 disrupted the lives of 20 million people – many more than the 2004 Indian Ocean tsunami – and cost $10 billion.
The climate change policy, developed with the support of the United Nations Development Programme (UNDP), recommends some 120 steps the country could take to slow down the impact of global warming, as well as adapt sectors such as energy, transport and agriculture.
Measures include flood forecasting warning systems, local rainwater harvesting, developing new varieties of resilient crops, promoting renewable energy sources and more efficient public transport.
"The National Climate Change policy takes into account risks and vulnerabilities of various development sectors with specific emphasis on water, food, energy and national security issues," said Rana Mohammad Farooq Saeed Khan, Minister for Climate Change at the launch of the policy is Islamabad on Tuesday.
But the policy needs a concrete action plan to back it up, with details, budgets and timelines first, some newspaper commentators said, adding that only then could there be a chance of effective implementation.
Questions have also arisen about where the money to fund implementation will come from and whether Pakistan's provinces have the capacity and expertise to put it in place.
Last year, a major U.N. report said the world needed to prepare better to deal with extreme weather and rising seas caused by climate change, in order to save lives and limit deepening economic losses.
UNDP's Pakistan Director Marc-André Franche said addressing changing weather patterns would help the country's economic development.
"Pakistan is among the most vulnerable countries facing climate risks and mechanisms need to be devised for greener, more resilient options for growth and sustainable development, said Franche at the launch.
"I hope the policy will help key stakeholders in identifying capacities and skills for the successful implementation of the policy," he added.

Here's Dawn on US energy help for Pakistan:
US Ambassador Richard Olson reiterated on Tuesday the commitment of the United States to extend full help and cooperation in resolving the energy crisis faced by Pakistan.
Addressing a function here at Tarbela Dam project, along with Water and Power Development Authority (Wapda) Chairman Syed Raghib Abbas Shah to recognise the completion of the US funded Tarbela Dam restoration project the US ambassador said, “The United States understands that Pakistan is facing an energy crisis and we are committed to doing our part.”
The restoration of three generators at Tarbela added 128 megawatts of power to the national grid.
He said, “The work completed here at Tarbela contributes enough electricity to supply two million customers, and helps provide relief to those suffering from extensive power shortages.”
Wapda Chairman Syed Raghib Abbas Shah appreciated the support of the United States to the energy sector in Pakistan.
The US Agency for International Development (USAID) provided $16.5 million to the Pakistan Wapda to repair three power generation units and to train Tarbela’s staff to operate the upgraded equipment to increase production of electricity at Tarbela.
Relieving Pakistan’s energy crisis is a top priority for US assistance to Pakistan, said Olson.
In addition to Tarbela, the United States is also funding other high impact projects, such as the rehabilitation of the Mangla dam, and renovation of thermal plants at Jamshoro, Guddu, and Muzaffagarh, which have already added over 650 megawatts since October 2009.
The US government is also co-financing the completion of the Gomal Zam and Satpara dams which will add another 35 megawatts and irrigate more than 200,000 acres.
Finally, the US is helping to replace thousands of highly inefficient agricultural and municipal water pumps throughout the country to save additional megawatts.
These projects are expected to add 900 megawatts to the national power grid by the end of 2013, enough energy to power two million households and businesses.
