Gno to the gnostics - Third Sector

http://www.thirdsector.co.uk/news/Article/980738/Gno-gnostics/
by Rosamund McCarthy

This is an article in Third Sector Magazine of 2nd February. I find it a compelling argument, rational, and very elegantly written. Anyone who despairs of understanding how evangelical missionaries etc can be deemed charitable should read. It's relevant to conservation, when the amount of charitable giving to conservation is compared with the amount given to faith organisation. Worth a read.

The God Delusion

Over a Christmas drink one of my neighbours, stimulated by seeing the faithful going to church on Christmas eve, made an interesting point, which distinguished 'believers' from 'non-believers'.

Non-believers often have very fulfilling lives, and at the end of their life can look back and think they may or may not have done something useful, creative or productive. But what about all those believers, from the pope downwards, who devote their lives to the service of what many of us think of as a delusion? If we are right and they are wrong, then a large part of their entire life has been wasted on a futile gesture (Even one hour a week in church adds up to the equivalent of about a year of ones life). At least the non-believers don't have this worry; doesn't this every bother them? And perhaps this is a major hindrance to wildlife conservation, and also why so many conservationists are non-believers (I include atheists, agnostics and anti-theists in this category). A Non-believer cannot just sit and pray that god will sort it all out, a non-believer is more likely to think that he or she must get on and do something. It would be an interesting area for reasearch.

Christmas is coming and the Goat is getting fat

Regular readers will know my views on goats, and will also know that there has been a massive drought and die off of domestic lo]ivestock in East Africa. Any details of what is happening, plus your views will be very welcome, as I am planning to write more on this subject.

Another week goes by....

My blogs are getting fewer and fewer. And for those that read them my apologies. However, the reason is that the World Land Trust is getting busier and busier. Despite the recession, we are getting more and more companies wanting to support us. I have mentioned this several times already, but it is still true. The current interest is clearly influence by the up and coming discussions in Copenhagen relating to Climate Change, and carbon offsetting. However, I think we are all missing one major issue, which is only faintly heard in the background. The 'elephant in the room' is the human population. Recent predictions indicate that the UK's population is going to grow to an unsustainable 70 million or more. But this is insignificant compared with the predictions for other parts of the world.

As far as I am concerned there are two over-riding priorities for conservation: first save as much of the world's natural habitats as possible, and second support any initiative that addresses the human population crisis. Everything else pales into insignificance by comparison. This is not to say that the myriad other conservation activities are not worthwhile, but without natural habitat in the future, captive breeding, research etc are all futile.

Copehagen and human population

The Copenhagen meetings did not focus on the one issue that drives our demand for fossil fuels and results in all the CO2. That is human population growth.

If I was trying to be controversial, I might suggest that far from trying to conserve energy and trying to develop renewable sources of energy we should be opposing these changes. Why? Because increasing the energy supply and keeping prices down will simply allow the human population to carry on increasing. How? Because cheap energy allows food to be grown in an otherwise unsustainable way, and that in turn will slow down the rate of human mortality from malnutrition (one estimate I read was that 18 million deaths a year are related to malnutrition, and that figure is probably rising). A cynical view, perhaps. But realistic from a biological perspective. Read Malthus if you are not convinced

However one looks at it, the human population cannot continue to increase indefinitely. Nor can economic growth be sustained indefinitely. History is bound to repeat itself, and in the past numerous civilizations have over-reached their resources, and crashed. It is bound to happen again. To me that is as certain as death and taxes. For millennia famine, disease and war have been a natural part of the human population control mechanism. And if they are repressed for too long then eventually they re-appear with catastrophic results. History teaches that very basic lesson, which Malthus understood all too clearly. And it will happen again, unless an alternative method of population control is implemented.

Britain is set to have a population of over 70 million, all squezzed into an area of less than 94,000 square miles, or just over 60 million acres. With large areas unsuitable for farming, and with so much of the prime agricultural land now covered with roads, buildings and other infrastructure, there is considerably less than a quarter of an acre per person for growing food. Clearly unsustainable -- and yet this is presumably the lifestyle that is being advocated for the so called less developed countries.

It is time for a wake-up call. The British government still subsidises children, millions of pounds are spent on infertility treatments, at a time when a significant decrease in the human population is essential in the medium term, if not in the short term. And in the long term, without population control, nature will intervene.

Meanwhile, every 11 seconds another person (net) is added to the population of the USA -- one of the most energy hungry nations in the world. That's nearly 3 million a year, all demanding economic growth and masses of cheap energy.

The politicians were certainly fiddling while Copehagen was burning.....

Water, water everywhere

The Fourth plinth in London's Trafalgar Square was used by a student from Ipswich to highlight water awareness. Dressed as a toilet, he carried a placard stating that "water and sanitation are human rights". PR from Water Aid, the charity backing him claimed that 2.5 billion people lack basic sanitation. Presumably this implies that everyone has a right to a flush toilet.

A great idea, But has anyone actually given any thought as to where all the water for this human right will come from? Or where all the toilet paper that will be flushed down these toilets will come from? Or where all the effluent will go? Like so many of the quick fix solutions to world poverty being inflicted on the less developed world, virtually no thought is given to the environmental impacts. I have tried to gather data on this topic, and would be really interested to see copies of any correspondence relating to EIAs [Environmental Impact Assessments]; I know for a fact that many aid charities do not carry them out, so it is always worth writing to charities to find out if they carry them out, and with what results. What is the Environmental impact of changing traditional farming methods to 'improved' western technology? What is the environmental impact of using artificial fertilisers, pesticides? What is the environmental impact of deep boreholes for water?

I do not have a problem with emergency aid, following natural or even man-made disasters, but long-term, so called development aid, is often ill thought out, with little or no thought about the long-term environmental consequences. And providing water for everyone to use with western style profligacy is one of the biggest potential disasters I can think of. Meanwhile, we at the World Land Trust are working with several of our partner NGOs, to conserve watersheds. They are just as important as the tropical forests that often grow around them.

Is a flush toilet a basic human right or is it a luxury?

Population press release

For this blog, I have simply pasted a press release from the Optimum Population Trust. The World Land Trust and OPT share the same Patron (Sir David Attenborough) and I believe that the activities of OPT are every bit as important as anything the WLT does. Politicians still avoid the P word, but human Populations are the only real threat to the planet. Read on.......

CONTRACEPTION IS “GREENEST” TECHNOLOGYFamily planning cheapest way to combat climate change
Contraception is almost five times cheaper than conventional green technologies as a means of combating climate change, according to research published today (Wednesday, September 9).
Each $7 (£4) spent on basic family planning over the next four decades would reduce global CO2 emissions by more than a tonne. To achieve the same result with low-carbon technologies would cost a minimum of $32 (£19). The UN estimates that 40 per cent of all pregnancies worldwide are unintended.
The report, Fewer Emitters, Lower Emissions, Less Cost, commissioned by the Optimum Population Trust from the London School of Economics*, concludes that “considered purely as a method of reducing future CO2 emissions”, family planning is more cost-effective than leading low-carbon technologies. It says family planning should be seen as one of the primary methods of emissions reduction.
Meeting basic family planning needs along the lines suggested would save 34 gigatonnes (billion tonnes) of CO2 between now and 2050 – equivalent to nearly six times the annual emissions of the US and almost 60 times the UK’s annual total.
Roger Martin, chair of OPT, said the findings vindicated OPT’s stance that population growth must be included in the climate change debate. “It’s always been obvious that total emissions depend on the number of emitters as well as their individual emissions – the carbon tonnage can’t shoot down, as we want, while the population keeps shooting up. The taboo on mentioning this fact has made the whole climate change debate so far somewhat unreal. Stabilising population levels has always been essential ecologically, and this study shows it’s economically sensible too.

“The population issue must now be added into the negotiations for the Copenhagen climate change summit in December.** This part of the solution is so easy, and so cheap, and would bring so many other social and economic benefits, from health and education to the empowerment of women. It would also ease all the other environmental problems we face – the rapid shrinkage of soil, fresh water, forests, fisheries, wildlife and oil reserves and the looming food crisis.

“All of these would be easier to solve with fewer people, and ultimately impossible to solve with ever more. Meanwhile each additional person, especially each rich person in the OECD countries, reduces everyone’s share of the planet’s dwindling resources even faster. Non-coercive population policies are urgently needed in all countries. The taboo on discussing this is no longer defensible.”
The study, based on the principle that “fewer people will emit fewer tonnes of carbon dioxide”, models the consequences of meeting all “unmet need” for family planning, defined as the number of women who wish to delay or terminate childbearing but who are not using contraception.*** One recent estimate put this figure at 200 million. UN data suggest that meeting unmet need for family planning would reduce unintended births by 72 per cent, reducing projected world population in 2050 by half a billion to 8.64 billion. Between 2010 and 2050 12 billion fewer “people-years” would be lived – 326 billion against 338 billion under current projections.

The 34 gigatonnes of CO2 saved in this way would cost $220 billion – roughly $7 a tonne. However, the same CO2 saving would cost over $1trillion if low-carbon technologies were used.

The $7 cost of abating a tonne of CO2 using family planning compares with $24 (£15) for wind power, $51 (£31) for solar, $57-83 (£35-51) for coal plants with carbon capture and storage, $92 (£56) for plug-in hybrid vehicles and $131 (£80) for electric vehicles.

However, the study may understate the CO2 savings available because the estimates of unmet need are based on married women alone, yet some studies suggest up to 40 per cent of young unmarried women have had unwanted pregnancies.

Mr Martin added: “The potential for tackling climate change by addressing population growth through better family planning, alongside the conventional approach, is clearly enormous and we shall be urging all those involved in the Copenhagen process to take it fully on board.”

**In a statement issued last month, OPT called on climate change negotiators to ensure that population restraint policies are adopted by every state worldwide to combat climate change. Family planning programmes in poorer countries should be treated as legitimate candidates for climate change funding. The statement was endorsed by OPT patrons including Sir David Attenborough, Dr. James Lovelock and Jonathon Porritt. See: www.optimumpopulation.org/submissions/climatechange09.pdf.

The authors calculate that in the US each child adds 9,441 tonnes of carbon dioxide to the carbon legacy of an average female, equivalent to 5.7 times her lifetime emissions.

Professional Fundraisers

As readers of my past blogs will realise, I have little time for professional fundraisers, and I have explained previously why the WLT has not signed up to the FundRaising Standards Board. Some time back, I read in the May issue of Professional Fundraising, that "more than a third of Fundraising Standards Board members have failed to submit obligatory complaints figures to the regulator".
And while I am writing about complaints, a couple of days ago Vivien received a massive envelope from the Red Cross, all very personalised, with cards, address labels and a pen, and a lapel badge -- it must have cost quite a bit to produce, and clearly the intention is to embarrass recipients into donating to the Red Cross. But only a couple of days previously we happened to have been to a local Red Cross Fundraiser in our village hall. So my immediate reaction is very negative indeed towards the Red Cross. I have always disliked giving 'free gifts' as an incentive for charitable donations, and like organisations that indulge in 'chugging' immediately put them on a black list for donations. And I wonder how many other people react in the same way. The problems is that these forms of fundraising do produce some results, and they are often fairly immediate, which is why professional fundraisers like them. But how many legacies and big donations are lost by the organisations indulging in such techniques? Any one else got views or experiences?

Green colonialism?

I picked up a leaflet about a scientific symposium being organised by the Zoological Society of London. The Title was Biodiversity Monitoring and Conservation:Bridging the Gaps Between Global Commitment and Local Action. A very worthy concept. But interestingly the list of contributors seems to be composed completely of representatives of the Big NGOs (BINGOs) and university and other institutions from the developed world. The views of those actually doing the action, implementing conservation, carrying out the monitoring do not seem to be involved. I recognise that this is not a symposium that will have any real executive functions, but it does seem a bit odd that so few (none?) of those at the sharp end are involved. The WLT is involved in a lot of programmes that involve monitoring -- to ensure the actions we are taking are effective, and most of this involves biodiversity in some way or other (or at least species diversity monitoring), but one thing we are certain of, is that unless the local conservationists are actively involved in all initiatives, there is a good chance that the conservation actions will not be sustainable. The ZSL has a reputation for being a bit reactionary, but one might have hoped that with over 20 speakers giving presentations, one or two might have been from organisations based in the less developed parts of the world, actually involved in the monitoring long-term; there are quite a lot of them.

more awards for conservation and charity

I have written about my dislike for awards in the past. Such as the Charity Times awards for 'Best charity'. In particular I dislike awards which require an entry fee, and even worse, often a large payment to attend the awards ceremony. And most of the people I have discussed this with agree with me.



But there are other awards, where agreement is rarer. And that is awards for individuals. There are a number of prizes that are given to individuals who are deemed to be significant in some way or other. But I also have serious reservations about giving awards to individuals, for a number of reasons. First, it is always very difficult to decide who deserves an award. Very often it is the pushiest person, as modesty is rarely rewarded. Second, awards frequently contain an element of political correctness. And third they feed the contemporary obsession with celebrity culture. But the backers for awards just love giving them to individuals, largely because of this latter reason -- they can generate more publicity. The reality is that while the charismatic individual can achieve a lot, ultimately it is organisations that make the real, sustainable, long lasting difference. The really good charismatic individuals do not need awards, but the organisations they represent and work for often struggle to get funds and recognition.



It was some while back that I began to have doubts about the value of rewarding individuals with conservation 'Oscars' when helping BBC Wildlife Magazine draw up a list of the most influential conservationists. And this list did not have prize money attached to it. The problem was, that even with a long list of only British conservationists, that it was a little bit like competitive team sports -- someone had to lose, and it did not mean that the losers were any worse, or the winners were any better. But we only ever hear about the elation of the winners. What about the depression of the losers? At least when it's an organisation it is not so dependent on an individual's ego, or presentation abilities. And at least with an organisation it stands a better chance of having a lasting effect.

New Naturalists hit by recession?

I happened to look at Collins' New Naturalists on sale on ebay, and it seems that they have been hit by the recession, as prices seem to be in free fall. The market for this remarkable series has seen incrdible prices paid for the rarer editions, but it has also seen many of the volumes changing hands among 'collectors' who are not actaully that interested in the contents, buit more interested in the condition of the dust-wrapper.m The advantage of this (to my mind, silly) market, is that it has enabled HarperCollins to publish many more volumes in the series than would otherwise have been possible. It is a great pity that a similar collectors' market did not develop for the World Naturalist series of Weidenfield and Nicolson. An equally important series in my vbiew, never surpassed, but alas, no longer being published.

Monitoring mega-expenditure of NGOs

My regular readers will know that I am a critic of foreign aid, and I am also a critic of Oxfam. I also monitor many websites of charities, mostly to see how they present themselves, and to ensure that any criticisms that might be made do not apply to the World land Trust. A major problem with any large charity is that it almost impossible to understand what really goes on when reading their accounts. When a charity the size of Oxfam presents its accounts, it is done in round millions, and it is almost impossible to know what these figure concern. The charity can give away as much or as little information as it likes. But it does lead to an enormous potential for misunderstanding. I am sure there are very good explanations, for example, on the Oxfam website it indicates that grants paid to overseas recipients in FYE 2008 totalled £16 million going to 50 organisations. Yet in the same annual rport it is stated that the UK payroll cost £93 million, with 25 staff earning over £60,000 p.a. As I wrote above, I am sure there is a perfectly good reason for these figures, but what it does show is how difficult it is to undertand accounts when they are hidden in fiogures with 6 noughts on the end.



One of the more obviousreasons can be found by looking at the sources of income, and since a huge amount comes from governments, it is likely that this is expected to be spent on UK staff so that it stays at home to be taxed, and therefore returned to sender....

Environmentally disastrous public transport

I have just been looking at the local railway service's website. There's an amazing array of special offers encouraging people to travel by train. And very environmentally friendly one might think. But is it? The answer is a resounding NO. Most of the journeys being made using these astounding special offers are undoubtedly not essential. An in many cases it is not a case of going by train instead of by car. It is simply encouraging people to travel more and more. And if the trains from Norwich are only half full with people making essential journeys, it makes economic sense to fill the rest of the train with cheap travellers. And that way the rail service is not only profitable, but it can justify itself.

Unfortunately this has been taken to new limits in London. Here, travel cards allow a cap to be put on the cost of traveling each day on the London Underground. However many journeys you make, it gets no more expensive. The upshot of this is almost certainly many people use their card for journeys of one or two stops, making the underground even more unpleasantly overcrowded, but at the same time allowing the operators to claim that public transport is incredibly popular.

I think a fact that most environmentalists promoting public transport have failed to grasp, is that public transport can only really be environmentally friendly, in a centrally controlled political system, such as once operated in the Communist world. I recall visiting Czechoslovakia in the 1960s when train travel was dirt cheap, car travel only for a few, bus travel more expensive than trains, and air travel too expensive for most people. With central controls, then all fares can be regulated to ensure the right balance is achieved. But with the type of free-for-all we now have, with subsidised fuel for air travellers, and all travel actually responsible to shareholders (which means there is a legal obligation to maximise profit above all other considerations), there is virtually no prospect of an environmentally friendly public transport system. And while I am at it, I will remind everyone, that air travel is now de facto part of public transport, and often much more fuel efficient than the average rural bus service. But of course there is a difference, in that most air travel is non essential. {Having written that, I realse that many rural bus services are now packed with pensioners swanning around on their passes, making them most of free travel.

More people travelling more and more. That's the real problem. And everyone wanting more of everything, and wanting it cheaper than before. Thereby driving the manufacture of goods overseas where environmental controls are less stringent, the production of food overseas where welfare standards are lower etc etc etc. Depressing. Perhaps a positive aspect of the economic downturn is that we are all realizing how much 'stuff' we all buy that we don't really need. Perhaps some politicians may even realise that continued economic growth is simply not sustainable if it is dependent on constantly expanding human populations.

Dead Aid by Dambisa Moyo

Dead Aid is a brilliant summary of some of the views I have been espousing for many years. The Authoress, unlike me, can back it all up with facts; she is a Zambian, who has worked in the World Bank, and her book is a devastating indictment of foreign aid in Africa. I am sure all the government aid agencies will dismiss it -- they would wouldn't they? And I am sure Oxfam, Christian Aid, St Geldorf and all the others trying to 'Wipe out Poverty in Africa' will dismiss it. And I am sure not every little detail is interpreted exactly right. But I am also sure that the overall thesis has hit the nail on the head.

Foreign aid is the cause of corruption and poverty in most of Africa. And anyone who thinks otherwise should read this book. Before giving another cent or Penny read it.

Emergency aid is one thing, and will always be needed, but so-called 'development aid' is quite a different matter, and this is the aid that actually helps prevent real development, and feeds corruption. And it also has often huge benefits to the donors. In fact after reading Moyo's account it seems that these are the only real long term beneficiaries: pop-stars, politicians and donors get a real feelgood kick out of it, meanwhile the poor get poorer, and the rich get richer.

As she points out, governments seem all to eager to listen to Bono and Geldorf -- but how often do they listen to those who actually live and try to work in Sub-Saharan Africa? Why should a pop-star know more than them?

I would actually go slightly further than Moyo, as I see elements of cultural imperialism in most aid programmes. Pushing cows that produce more milk into African economies, where the majority of the inhabitants are lactose intolerant is a classic example. I would also argue that there is little difference between the cultural imperialism of the 21st century and the Missionary zeal of the 19th century. The end results are not dissimilar: a form of ethnicide.

Volunteer Travellers

In the course of work today I had cause to look at a couple of websites for volunteer travellers -- those going abroad to do good works. In fact while the intentions are often very good, I do have serious reservations about how much real good most of these young travellers do, For a start they can often be taking away employment from locals. The average trip will cost the volunteer something around £1500-£3000 for a month's 'holiday' -- often a year's employment for a local. But more important is the lack of transparency of many of the companies involved. Most of the young altruistic volunteers assume that the companies are also philanthropic. But a quick look at the websites reveals...... very little. Unlike charities, they do not have to publish their accounts, nor reveal who is paid what.

Whenever I am asked about gap year volunteering, or 'expeditions' I always say 'caveat emptor'. Earthwatch and a few (relatively few, I am afraid) do a great job, but there are a lot of others who are little more than travel companies with the profits going to the shareholders or ownwers -- even when they appear altruistic.

IUCN in retreat

IUCN -- the International Union for Conservation of Nature and Natural Resources-- has just had a retreat. So I read in their newsletter today. And I always find the concept faintly worrying. To start with the idea of being in retreat has a distinctly negative connotation. And even if I sweep that aside, it then has a rather austere, monastic inference. Neither appeals to me. And while it might be a useful function, for the staff and board members to get together, I am not sure it is something that deserves publicity. Cynics in the conservation world have suggested that IUCN stands for International Union for Conversation about Nature, or even worse, I Used to Conserve Nature. The fact remains that too many meetings, with too many delegates are what IUCN has become known for. We need fewer conferences, fewer meetings, less research and more action. Much more action.

Needless to say there was no mention of the most serious of all conservation issues: human populations. IUCN seems to avoid this much of the time. But I was glad to hear over the weekend, that Sir David Attenborough has beome patron of the Optimum Population Trust.

Flying off to Sicily

Last Thursday I flew off to Sicily for a long weekend. Recharging of batteries etc. It was one of the best times of the year for seeing orchids, and we saw loads of them, together with masses of other wild flowers, plus migrating birds of prey. But of course many people then criticise trips like this -- flying and all that carbon footprint. How do I justify it? The answer is, I don't really have any logical justification. It does have a carbon footprint, but since on the whole I lead a relatively low-carbon life, I suppose I feel, a little bit of indulgence is justified. Furthermore, my raison d'etre for conserving wildlife, is my own personal enjoyment of it. But while flying, I did feel that the best way of reducing the amount of carbon is to ensure that fair and realistic prices are paid for air travel. And certainly it is getting much more expensive, and there were fewer people on the plane. But it's a dilemma which is not easily solved. What do others who fly a lot feel about this?

Easter weekend

A few days away from the office, and some glorious spring weather. Slow worms were under the sheets of corrugated iron that I have strewn around the garden to provide a hiding place for them. Also a common shrew and a bank vole were under the sheets as well. The dawn chorus seems a bit better than recent years with at least four singing male blackcaps. And I saw my first swallow on Saturday. And best of all, in our tiny patch of woodland, I found a nice crop of Morels -- a spring fruiting fungus, that is truly delicious.

And an interesting piece of behaviour. Over winter I have kept our five Japanese Quail in the greenhouse -- they hate the wet cold English winter, and seemed very happy, and became exceptionally tame. On Sunday, I decided to put some seed trays in the green house, and gave it a thorough wetting, and the quail also had a great time in the shower. Then next day their behaviour totally changed. They became very flighty -- they had only ever run around, never taking flight -- and very vocal. Did the shower I had given them, trigger a migration response? Unfortunately none of the books I have (including the Handbook of Birds of the World give any information that enlightens me on this. Any leads from my readers would be
welcome.

And so today, back to work, with a few donations resulting from Simon Barnes' article in the Times (fewer than I expected, probably because with the beautiful weekend weather, no one was reading their papers, they were all in the garden!)

Wildlife, rainforests and vegetarianism

A few of WLT's supporters have suggested that being vegetarian is a way of saving wildlife and rainforests. As is so often the case, the answers are never that simple.

I was brought up a vegetarian (unusual in the 1940s and 50s), but changed in the 1960s to an omnivore diet. The fact is that while there is no question that we do not need to eat the vast quantities of meat that 'developed' (i.e. rich) societies eat, an omnivore diet actually makes as much sense as a vegetarian diet. Grazing sheep on upland pastures can be an efficient way of maintaining interesting habitats, and even in vegetarian areas of India cows are kept to provide manures.

More controversial is the fact that huge areas of rainforest have been devastated for the production of soya beans, which are among the mainstays of vegetarian and vegan foods. The more responsible soya producers only use organic soya, but even those do often get it from areas that were historically rainforest.

My personal belief is that the answer does not lie in vegetarianism per se, but in eating very limited amounts of high quality (organic, pesticide free, locally produced, cruelty free) meat, and locally produced vegetables when ever possible. But international trade is also important to benefit the poorer parts of the world, so ethically and environmentally friendly rice and other cereals etc should not be ignored.

Unfortunately there is no simple answer, other than simply reducing the size of the human population and its aspirations to ever increasing material wealth.
