The Kerry Lugar Distraction

The Kerry-Lugar Bill has become the black-hole of Pakistani political debate. Its din of conflicting rhetoric and opinion drowns out everything else. Even good sense. Sovereignty, which reference to any nearby encyclopedia will tell you, is a quality, possessed by a sovereign, of having supreme and complete control over a territory. In light of the KLB (it’s even got its own acronym), we seem to have gotten this concept mixed with ghairat. While all this is most amusing, it is no substitute for meaningful debate about the future of this country.

Too many others have offered their expert opinion on the new American administration’s attempt to change how and whom it funds in this Islamic Republic. It’s mildly surprising how so much of the debate has remained centered on the idea that Pakistan’s “sovereignty” (may Allah bless it and protect it with the Bomb) will be irrevocably tarnished. This is an old debate that has its antecedents in our characteristic dependency on the United States and paranoid concern of what others think of us. I’m surprised that the debate hasn’t moved beyond the hackneyed jingoism we’ve been forced to read and hear these past few weeks. I’m surprised that so little of the debate has dealt with the reality that it’s basically the folks whose names have been left off the payroll who are hopping mad at being passed over. But that just proves that KLB is a massive black-hole of political debate.

While the KLB debate goes on consuming all the air in the room, the real challenges this country faces remain unaddressed. We are a country of nearly 170 million mostly poor and illiterate people that is facing an energy crisis, a population explosion and potential water scarcity. Environmental degradation already costs the economy at least Rs. 1 billion a day and kills hundreds of thousands of us a year. And soon we will be forced to play one of the worst hands Nature has ever dealt man: Climate Change and the water scarcity, food shortages, population migrations, increased incidents of disease and natural disaster it will bring. To this equation, add the variables religious extremism, militancy and terrorism.

And here we are, with this KLB debate, talking of nothing but whether or not it is acceptable for Pakistan to be a beggar and a chooser. I would think that saner counsel (“get whatever you can get and be thankful”) would prevail.

In the next ten years, it is estimated that rural to urban migrations will transform our rustic rural people into an urban people. It’s estimated that, by 2050, as many as 65 percent of Pakistanis will live in cities. The failure of population stabilization policies means that, by then, there will be nearly 300 million Pakistanis. Three challenges immediately come to the fore.

First, where are you going to get the electricity? We’ve got a woefully inadequate installed capacity somewhere in excess of 20,000MW, nearly 25 percent of which is wasted in an efficient distribution and transmission system (a day ago, I read that, “because of forced closures, fuel shortages and some scheduled closures”, the PEPCO system is only generating 11,750MW). The Planning Commission estimates that, by 2030, Pakistan will need approximately 164,000MW of electricity to meet it demands. Of course, at the moment, such an amount seems impossible and if efforts don’t start now to increase installed capacity, improve line-losses and think up ways of jumping to a “smart grid”, the our ability to industrialize our economy will be compromised.

Second, will there be enough water? About 90 percent of our water resources are consumed in irrigation, yet unlined canals, water theft and out-dated farming practices mean that 40 percent of this is lost to inefficiency. The remaining 10 percent of our water resources are consumed as drinking water and for sanitation. Almost all of our water resources are from glacial melt. At Partition, our water resources stood in excess of 5,000 cubic meters per capita. Now, they are fast falling to less than 1,000 cubic meters per capita. The rate at which climate change is affecting glacial melt have surprised researchers, and it is predicted that, after accelerated melting (which means flooding and lots and lots of silt) our glacial water resources will be depleted. This is set to happen in the next 100 years.

Third, will there be enough food? Climate Change, outdated farming practices and depleting water resources will have an effect on food productivity. All of our cash crops are going to be affected by Climate Change. Of course, there will always be mitigation and adaptation, but even if food production can be maintained through science and discipline there is no telling the effect on rural economy and society. Certainly Climate Change will contribute to the great desire of people to move from the labor of subsistence farming to the potential offered by the cash economy of an urban area.

Parenthetically, let me again mention the proposal to lease hundreds of thousands, if not millions, of hectares of arable land to certain Arab is a bad idea that hasn’t been clearly thought out yet. Also, how come no one raises the question of sovereignty at the thought that our government was/is to negotiate the lease of such land under the guise of foreign investment? The Lahore High Court has done the right thing, while disposing of a petition filed before it by a farmers union, by requiring any such negotiation be brought to its notice.

An increase in the number of people in cities will put stress on the availability of housing, sanitation infrastructure, employment opportunities, healthcare facilities, educational institutions, transportation services and recreational space. All these are already stretched beyond capacity, but nobody involved in the windbag KLB debate seems to have an eye on what’s around the corner.

The three challenges highlighted above also overlap, in one way or another, with the role of the city. The centrality and importance of urban management in the future of Pakistan must not be underestimated. In the near future, the issues of housing, sanitation, employment, health, education and poverty will all primarily be urban issues. Even issues like energy can be regulated by the of size and manner in which our cities are run. The latest sustainable development initiatives are experimenting with "urban farming" to reduce emissions resulting from the transport of produce from the field onto the dinner-table. Urban areas produce disproportionately large quantities of the world’s green house gas emissions, and for sure Climate Change mitigation and adaptation strategies have huge urban components.

At the moment, our cities are managed by junior to mid-level bureaucrats acting on the instructions of provincial governments (though the City District Government of Karachi, it must be said, is the most independent) that have woefully little knowledge of what makes cities tick. At the moment, they are centers of sprawl, congestion and pollution with rapidly growing katchi abadis and slums. Yet, while these challenges seem insurmountable, they are, in fact, completely manageable. Enrique Penalosa, the charismatic former Mayor of the Colombian city of Bogota who transformed his city in only three years, told me once that the only thing we need to do to start is a vision of the type of city we want to live in.
Now wouldn’t that be a debate worth having?

Climate Change affecting agriculture in Karachi

Here's a chilling article about the effects climate change is having on our urban areas.

Climate change affecting agriculture in Karachi

Karachi

Researchers from the University of Karachi (KU) Department of Geography have discovered the relationship between climate change and increase in the incidence of diseases, and the decrease in agricultural products in and around Karachi.

Former chairman of the department Dr Syed Jamil Hasan Kazmi along with his team of researchers worked on the impact of global warming on agriculture in Karachi on vector-born diseases (Malaria and Dengue) and the transformation of ecological systems within the mega city. Dr Kazmi has been working in Gadap, Kathor, Malir, Memon Goth, Darsano Channa and Hub agricultural areas for 20 years. “These were the fertile areas in 60s and provided fresh fruits and vegetables to the city. The mammoth growth of the city adversely affected the agriculture. Now the city meets only 10 per cent of the demand for fruits and vegetables from these areas.”

The irrigation of these agricultural lands was usually through the wells that were providing water after digging 20-30 feet below the surface. The rainfall pattern in the city has changed drastically since 1985, decreasing the frequency and intensity of rain in the city. This has resulted in drought of underground water levels. Now water can only be 400-500 feet deep. The high temperatures have evaporated the rain water quickly leaving the underground water levels dry. Two small ‘Check Dams’ have been built in Thuddo (North East of Super Highway) but it is sufficient for a 20 km area only.

“These people are living in the area for more than 300 years. Agriculture, which is their livelihood, is threatened by the change in climate and urban encroachment over the suburbs of the city. Now they have started sand mining in their areas to compensate for the loss of the agricultural production. This is very harmful as the unchecked removal of sand will create more ecological problems”, says Dr Kazmi.

According to Dr Kazmi, fruits and vegetables grown in the area cost more than the ones coming from Badin, Thatta, Sajawal, Hyderabad, Mirpurkhas, Tandojam and Rahim Yar Khan. “It is highly priced due to the shortage of water and extensive labour required to grow the crops in a semi-arid environment”, he explains.

Another effect of the lowering of the ground water level is the advance of sea water which causes salinity, due to which land ceases to be fertile. The Total Dissolved Solids (TDS) in these areas have a density of 3500 mg/litre compared to the World Health Organisation’s standard of 500 mg/litre. Elevated total dissolved solids can result in water having a bitter or salty taste, and can result in incrustations, films, or precipitates on fixtures, corrosion of fixtures, and reduced efficiency of water filters.

“Water is a good solvent and picks up impurities easily. Dissolved solids include any minerals, salts, metals, cat ions or anions dissolved in water. TDS comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates) and some small amounts of organic matter”, Dr Kazmi elaborates.

The mangroves also need fresh water, and due to saline water, these valuable plants wither and ultimately die. This has resulted in Pakistan sliding down the world ranking for mangroves from 13 to 21. With the country heading for an environmental disaster, concerned individuals in the government and in the civil society have pinned their hopes on the Intergovernmental Panel on Climate Change (IPCC).

IPCC is a scientific intergovernmental body set up by the World Meteorological Organisation (WMO) and by the United Nations Environment Programme (UNEP) to provide the decision-makers and others interested in climate change with an objective source of information about climate change. It was established by the WMO and UNEP in 1988 given that climate change is a complex issue, and policymakers need objective sources of information about the causes, consequences and measures necessary.

Measures for Clean Energy

Below is an op-ed by Arif Pervaiz of the Clinton Climate Initiative that was published in Dawn


THE world is moving in the direction of a low-carbon economy not because it can afford the luxury — no one in today’s world has spare change — but because investments in energy efficiency and clean energy can create jobs, reduce waste, help revive economies and lower harmful greenhouse gas emissions that are causing global warming.

Some argue that for Pakistan, whose total carbon emissions are minuscule — measuring less than 0.4 per cent of the global total — reducing greenhouse gas emissions is not a priority.

Wrong. What we should be looking at instead is our carbon intensity — measured in terms of greenhouse gas emissions per unit of GDP. Pakistan ranks in the bottom 14 out of 185 countries for its carbon intensity. Simply put, there are a lot of inefficiencies and wastage in our use of energy.

Actions aimed at greenhouse gas emissions reduction can result in better energy efficiency, less wastage, reduced pollution and improved public health. For these reasons, greenhouse gas reduction or ‘mitigation’ measures are important for us and should be part of our climate change strategy.

There are numerous initiatives that can be undertaken. Quite obviously we need to stem the ongoing haemorrhaging in our electricity system — 40 per cent of the electricity generated is lost. Why don’t the system’s losses get as much attention as talk of installing additional capacity?

Deployment of renewable energy as part of our energy mix has been very slow in coming. We need to devise a meaningful and ambitious plan for on-grid and diffused — district, neighbourhood and household — deployment of wind, solar PV, solar thermal, micro-hydels and other appropriate renewable technologies. The market for renewable energy solutions is emerging, but it needs

more support. Electricity loss reduction and renewable energy are viable solutions that should be focused on.

Another area in need of focus is transport and clean fuel. Rails and buses can carry more people per unit of energy consumed than private cars, but our investment priorities are highly focussed on the promotion of the use of private cars by a small elite. We need to start charging the real cost of car use and simultaneously develop effective mass transit systems. Car use should be taxed higher along with congestion and road-use charges, and car-free days should be introduced to encourage a shift to public transport.

It is important that any mass transit should be based on the local context, rather than technology. Subways and metros might appear attractive but they are very expensive and hard to maintain. Cheaper options like a Bus Rapid Transit System — planned for Karachi — are more appropriate, which partly explains why 80 cities around the world have or are in the process of developing a BRTS.

Mobility needs of the non-car-owning majority will require the building of extensive networks of navigable footpaths and bicycle tracks — this is important also from a public welfare standpoint. Especially when one considers the restricted recreational spaces available to families numbering eight, 12, sometimes 20 who live squeezed into tiny homes in congested localities.

Improvement in urban mobility and public health will have to include measures such as phasing out dirty-and-old buses, and two-stroke engines. Our refineries and petroleum suppliers need to start providing cleaner fuels — low sulphur diesel, pre-mixed fuel for two-stroke motorcycles — which have been promised for long. PSO has taken encouraging steps towards the production of bio-diesel. Production and deployment of bio-fuels — which don’t displace food crops and don’t require much freshwater — should be expanded and taken to scale.

There is vast untapped potential for generating energy using municipal waste. Some work is being done on this in Karachi, Lahore and Faisalabad, but needs support for wider development. Electricity generation through methane capture (at wastewater-treatment plants), and processing construction and demolition waste for reuse in construction, should also be explored.

Karachi dumps 400 million gallons of wastewater including raw sewage directly into the sea everyday. Lahore and other major cities also dump their untreated waste into fields and water bodies. This egregious act defiles the environment, kills aquatic life, and creates a public health hazard. In many areas around the country, sewage water is used to grow vegetables. Karachi desperately needs implementation of the city government’s Sanitation III project, which promises to put an end to this mindless practice.

Technology and expertise are available to treat all of this sewage water for reuse, and supply it to industry, and for urban farming and parks. The water savings from this could offset the need for large additional investments in urban water supply, provide an opportunity to use precious money for other social and economic investments and improve our environmental capital. We should also look to save billions of rupees by improving energy efficiency of equipment and processes at our water and wastewater utilities — where there is tremendous scope for savings.

Key to progress on realising benefits of a cleaner and more energy-efficient environment will be the institutional arrangements we craft. The main driver of a low-carbon economy will be the private sector, bolstered by the state’s policy and regulatory bodies for environment, availability of easy financing and local and international assistance. To play a meaningful role, relevant NGOs will need to go beyond generic ‘awareness raising’ to organising technical training, fostering linkages with local universities and technical institutions, and bringing in relevant international expertise.

A coherent climate change strategy should be formulated and pursued through a high-level, well-resourced and independent body, e.g. a climate change council, with representation from industry, business, professional bodies, universities, NGOs, donor agencies and concerned government departments, which can guide, direct and support climate change-related activities.

Additional technical and financial support required should come from bilateral and multilateral institutions and from our friends like the US and EU who can structure their aid in ways that promote ‘green’ investments.

Far from being a tree-huggers’ wish list, the actions discussed above have the potential to create thousands of employment opportunities for skilled and unskilled people, revive our engineering and technical institutions, increase capacity and business opportunities for the private sector, upgrade our infrastructure, and save hundreds of millions of dollars by reducing waste. Oil prices might be low now but they will increase again soon, and so it is a question of ensuring energy security for an uncertain future. The private sector and international financial and technical assistance will be important drivers in the move to a low-carbon economy, but it is that all-elusive political will which will determine the pace and extent of the change.
