Afghanistan The Central Asian Tar Baby by Gregory K. Taylor

The recent covert operation of 2 May, 2011, that resulted in the assassination of Osama bin Laden in Abbottabad, Pakistan drew America's attention back to the war in Afghanistan. The longest war in America's history, unlike other shooting wars, flies well below the conscious radar of most Americans. This is quite understandable considering that we occasionally hear about it when we are watching the news or when we see the death count at the end of a related program. Otherwise, we are required to make no visible, conscious, sacrificial effort that would remind us of the war; and honestly we're just too damn busy struggling to survive.
When I heard about the assassination, I went searching for a paper I wrote a few years ago on Afghanistan and its history. A fairly comprehensive explanation of how Afghanistan came to be, its struggle with foreign powers, and its religious fervor.
Lamenting the last year of floods, famine, and earthquakes which have bedeviled Afghanistan, a woman asks about the most recent earthquake of 31 May 1998, "What kind of curse has God put on our country?" (Oakland Tribune) And to illustrate the geopolitical concerns of bay area Afghans regarding human suffering as it relates to regional nuclear weapons testing. Tufa Ahmad of Fremont, California stated, "The earthquake is a disaster we can't do anything about. We're prone to disasters. But people in the world should know that Afghanistan is more dangerous than any atomic bomb. People there have suffered so much, they're going to explode." (Oakland Tribune)
What this Afghan (presumed) refugee/expatriate alludes to is the historical calamities that have beleaguered Afghanistan almost from its inception. Afghanistan has been manipulated, exploited, and militarily occupied by expansionist and colonial powers. During the past two decades Afghanistan has suffered from a precipitous drop in population due to death and disease caused by warfare. Between April 1978, when a violent coup d'etat brought to power a radical pro-Soviet political party, and early 1986 perhaps one-third of the populace fled the country. According to the United Nations, this constituted the largest refugee population in the world." (Nyrop and Seeking xxi)
Afghanistan, historically, has been a heterogeneous society, and like the rest of Central Asia the majority of people belong to the Sunnis Islamic sect (approximately two-thirds) and the remaining one-third is affiliated with the Imani Shiism faith--all are Muslims. These contentious groups were nationalized into one nation in 1747 by Ahmad Shah. "His success in war, piety, justice, wise political leadership, and conformity to the traditions of the Pushtuns won him a great deal of popular support, and his name became revered in Afghan history as the father of his country, Ahmad Shah Baba." (Magnus, Naby 30) Ahmad Shah conducted many military forays against non-Muslims acquiring an empire the distance to present-day Iran and India. Subsequent hereditary rulers over the years became more and more litigious. As a result, the empire fractured into sundry principalities, the precursor to the demise of Afghanistan's Golden Age Empire.
Geopolitically, the major players were the empires of Britain and Czarist Russia with the chess game being played out in Central Asia--and the various pieces being strategically positioned in opposition. "As in earlier times, two great empires confronted each other, with Central Asia lying between them. The Russians feared permanent British encroachment into Central Asia as the British moved northward taking control of the Punjab, Sind, and Kashmir. Equally suspicious, the British viewed Russian absorption of the Caucasus and Georgia, Kirghiz and Turkmen lands, and Khiva and Bu khara as a threat to British interest in the Indian subcontinent." (Nyrop and Seeking 24)
Subsequent wars like the first Anglo-Afghan war, euphemistically named, Auckland's folly, resulted in Russia's absorption of territories that once belonged to Ahmad Shah Durran's empire left Britain totally befuddled. Russia's hegemony over Central Asia in general and Afghanistan in particular was not to be easy--and it was thwarted in the final analysis by societal tradition.
These indivisible traditions related strongly to community land and its concomitant state irrigation system. "Land cannot be separated from the irrigation system and therefore from any community as a collective user of the irrigation system." (Malik 98) Czarist Russia at first maintained community coherence by preserving traditional structures, but later, in apparent contradiction, precipitated a revolt in both Central Asia and Kazakhstan by attempting to alter the norms of traditional society. Traditions are so deeply embedded in the psyche of Central Asia that land reforms instituted by the government of Afghanistan was the genesis of the Afghan resistance. Central Asia's over-all decline of its intellectual base, as it relates to tradition, is directly proportional to societal standards. For one, the study of technology is not encouraged--to do so would deprive the rural community of expert assistance, and without the requisite technical skills the infrastructure of a country will be forever wanting.
"Totalitarianism" of any sort, be it religious or otherwise, engenders a national brain-drain. Consequently, a student of non-Central Asian extraction is more likely to enroll in technical school and upon graduation will leave the country if prevailing government interest in his skills are lacking. So, the Central Asian student is grounded in subjects that perpetuate--if you will---Traditional Values. "Students of Central Asian nationalities prefer to study history, especially history of their own people or that of bordering Muslims countries. They concentrate mostly on studying ancient and medieval history, ethnography, and archaeology. The central Asian intellectuals believe that all that is theirs is 'good.' The source of this perception lies in the denial of everything that contradicts tradition. There own national values are given preference." (Malik 103)
Into this mix comes the liquidation of the Soviet Union with an increasing Islamic fundamentalism epicentrally in Tajikistan. "Independence came to the Central Asian republics not as a result of a victory of the national-liberation forces; it came as a 'present' after the liquidation of the Soviet union by the three leaders of the Slavic republics: Russia, the Ukraine, and Byelorussia (AKA: White Russian Soviet socialist Republic). The main theater of instability in Central Asia is Tajikistan. It is not an accident, in this republic all negative peculiarities typical of Central Asian republics reached their apex; deformed and weak economy, overpopulation, unemployment, low level of mass culture, religious fanaticism, and arrogance of local intellectuals." (Malik 111)
In close proximity to one another, Afghanistan and Tajikistan helped to propagate fundamentalism into Central Asia. Russia was unable to stop the flow of arms from neighboring Pakistan into Afghanistan. The border apparently leaked like a sieve with the porosity of Swiss cheese and all attempts at interdiction failed.
"Weapons and ammunition continue to cross the border from Afghanistan. According to the deputy chief of the Russian border troops stationed in Tajikistan, groups of fighters from Tajikistan, including not only Tajikis but Uzbeks as well, receive military training in the Afghan province of Kunduz. Hekmatyar's commanders head the forays into Tajikistan. The power-grab process by the Afghan fundamentalists that was predicted is apparently under way." (Malik 112)
From the day Iran seized American embassy personnel and paraded them on the world stage as hostages for over a year, Islamic fundamentalism and its far-reaching tentacles have been feared and talked about, much like the domino theory of the Viet Nam war. "In 1972, Habib ur-Rahman, one of the founders of the Islamic party of Afghanistan, said: 'We do not recognize borders. The day will come when Muslims of all the world will live under a common flag with the same coat of arms. If we attain power we shall struggle for Islam in Afghanistan and in the whole world, where our brothers live under the yoke of communism. Are the inhabitants of Bukhara, Samarkand and Tajikistan not Muslims? What about the Tatars? Are they not our brother?'" (Malik 113)
Afghanistan's history is replete with territorial land grabs. "At first the Afghans were a dynamic and expansionist empire, the last successors to the Central Asian imperial tradition of the Kushans, Huns, Ghaznavids, Seljuks, Mongols, Timurids, and Uzbeks." (Magnus, Naby 60) Only the rise of Europe as an expansionist power brought to an end such domination.
Afghanistan's religious zeal, and the concept of borderless Islam, meets with some success in Central Asia. "Of all the states in the region, Afghanistan is the only one that continues to press for the adoption of universal Islamic practice…" (Magnus, Naby 172) It appears that even the Iranians no longer hold such a world view. Perception of Islam as a unified power must be reckoned with as a serious threat to the geopolitical status-quo. The superpower bipolarity of the past has given way to the existence of one superpower, the United States, which sees itself under threat by Muslims. Hence a future unified Muslim region, such as Central Asia, can potentially come to be regarded as a threat not only in the eyes of some U.S. policy makers but also from the perspective of a Russia embroiled in proxy and direct war with Muslim radicals (Tajikistan).
To be sure, there are a few die-hard Islamic states and the move toward sectarian governance is on the rise, however, in general what has resulted in the fallout of such religious ferocity is a hybrid of the two; that is, a combination of secular and sectarianism. The Central Asian countries that employ such a combination are Azerbaijan, Uzbekistan, Tajikistan, and Kyrgyzstan--with Afghanistan being the lone Islamic state.
It is unclear to what extent Afghanistan will continue to influence its neighbors. It has cracked down on its population to such a degree even most Islamic nations muse with incredulity. The wholesale firing of women from their jobs cuts off Afghanistan's metaphoric nose to spite its face. The veil and all it entails is back in vogue and the men are required to don beards under threat of punishment. Refugees who once had dreams of returning home remain abroad. Tufa Ahmad's prognostication of impending disaster from Afghanistan appears to be inevitable. As to whether it will garner world attention remains to be seen.

The coconut crab, Birgus latro, is a species of terrestrial hermit crab, also known as the robber crab or palm thief. It is the largest land-living arthropod in the world, and is probably at the upper size limit of terrestrial animals with exoskeletons in recent Earth atmosphere at a weight of up to 4.1 kg (9.0 lb). It is found on islands across the Indian Ocean and parts of the Pacific Ocean as far east as the Gambier Islands, mirroring the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar.
The coconut crab is the only species of the genus Birgus, and is related to the terrestrial hermit crabs of the genus Coenobita. It shows a number of adaptations to life on land. Like hermit crabs, juvenile coconut crabs use empty gastropod shells for protection, but the adults develop a tough exoskeleton on their abdomen and stop carrying a shell. Coconut crabs have evolved organs known as "branchiostegal lungs", which are used instead of the vestigial gills for breathing. They cannot swim, and will drown if immersed in water for long. They have developed an acute sense of smell, which has evolved convergently with that of insects, and which they use to find potential food sources. Mating occurs on dry land, but the females migrate to the sea to release their fertilised eggs as they hatch. The larvae are planktonic for 3–4 weeks, before settling to the sea floor and entering a gastropod shell. Sexual maturity is reached after about 5 years, and the total lifespan may be over 60 years.
Adult coconut crabs feed on fruits, nuts, seeds, and the pith of fallen trees, but will eat carrion and other organic matter opportunistically. The species is popularly associated with the coconut, and has been widely reported to climb trees to pick coconuts, which it then opens to eat the flesh. While coconut crabs can climb trees, and can eventually open a coconut collectively, coconuts are not a significant part of their diet. Coconut crabs are hunted wherever they come into contact with people, and are subject to legal protection in some areas. In the absence of precise information, the IUCN lists the species as Data Deficient.
Description
Birgus latro is the largest land-living arthropod in the world; reports about the size of Birgus latro vary, but most sources give a body length of up to 40 cm (16 in), a weight of up to 4.1 kg (9.0 lb), and a leg span of more than 0.91 m (3.0 ft), with males generally being larger than females. The carapace may reach a length of 78 mm (3.1 in), and a width of up to 200 mm (7.9 in).
The body of the coconut crab is, like that of all decapods, divided into a front section (cephalothorax), which has 10 legs, and anabdomen. The front-most pair of legs has large chelae (claws), with the left being larger than the right. The next two pairs, as with other hermit crabs, are large, powerful walking legs with pointed tips, which allow coconut crabs to climb vertical or overhanging surfaces. The fourth pair of legs is smaller with tweezer-like chelae at the end, allowing young coconut crabs to grip the inside of a shell or coconut husk to carry for protection; adults use this pair for walking and climbing. The last pair of legs is very small and is used by females to tend their eggs, and by the males in mating. This last pair of legs is usually held inside the carapace, in the cavity containing the breathing organs. There is some difference in colour between the animals found on different islands, ranging from orange-red to purplish blue; in most regions, blue is the predominant colour, but in some places, including the Seychelles, most individuals are red.
Although Birgus latro is a derived type of hermit crab, only the juveniles use salvaged snail shells to protect their soft abdomens, and adolescents sometimes use broken coconut shells to protect their abdomens. Unlike other hermit crabs, the adult coconut crabs do not carry shells but instead harden their abdominal terga by depositing chitin and chalk. Not being constrained by the physical confines of living in a shell allows this species to grow much larger than other hermit crabs in the family Coenobitidae. Like most true crabs, B. latro bends its tail underneath its body for protection. The hardened abdomen protects the coconut crab and reduces water loss on land, but has to be moulted periodically. Adults moult annually, and dig a burrow up to 1 m (3 ft 3 in) long in which to hide while vulnerableIt remains in the burrow for 3 to 16 weeks, depending on the size of the animal. After moulting, it takes 1 to 3 weeks for the exoskeleton to harden, depending on the animal's size, during which time the animal's body is soft and vulnerable, and it stays hidden for protection.

Respiration

Except as larvae, coconut crabs cannot swim, and they will drown if left in water for more than an hour. They use a special organ called abranchiostegal lung to breathe. This organ can be interpreted as a developmental stage between gills and lungs, and is one of the most significant adaptations of the coconut crab to its habitat. The branchiostegal lung contains a tissue similar to that found in gills, but suited to the absorption of oxygen from air, rather than water. This organ is expanded laterally and is evaginated to increase the surface area; located in the cephalothorax, it is optimally placed to reduce both the blood/gas diffusion distance and the return distance of oxygenated blood to thepericardium. Coconut crabs use their hindmost, smallest pair of legs to clean these breathing organs and to moisten them with water. The organs require water to properly function, and the coconut crab provides this by stroking its wet legs over the spongy tissues nearby. Coconut crabs may drink water from small puddles by transferring it from their chelipeds to their maxillipeds.
In addition to the branchiostegal lung, the coconut crab has an additional rudimentary set of gills. Although these gills are comparable in number to aquatic species from the families Paguridae and the Diogenidae, they are reduced in size and have comparatively less surface area.

              The coconut crab has a well developed sense of smell, which it uses to locate its food. The process of smelling works very differently depending on whether the smelled molecules are hydrophilic molecules in water or hydrophobic molecules in air. As most crabs live in the water, they have specialised organs called aesthetascs on their antennae to determine both the concentration and the direction of a smell. However, as coconut crabs live on the land, the aesthetascs on their antennae are shorter and blunter than those of other crabs and look more like those ofinsects. While insects and the coconut crab originate from different evolutionary paths, the same need to detect smells in the air led to the development of remarkably similar organs, making it an example of convergent evolution. Coconut crabs flick their antennae as insects do to enhance their reception. They have an excellent sense of smell and can detect interesting odours over large distances. The smells of rotting meat, bananas, and coconuts, all potential food sources, catch their attention especially. Research has shown that the olfactory system in the coconut crab's brain is well-developed compared to other areas of the brain.


Coconut crabs mate frequently and quickly on dry land in the period from May to September, especially between early June and late August. Male coconut crabs havespermatophores and deposit a mass of spermatophores on the abdomen of the female; the abdomen opens at the base of the third pereiopods, and fertilisation is thought to occur on the external surface of the abdomen as the eggs pass through the spermatophore mass. The extrusion of eggs occurs on land in crevices or burrows near the shore. Shortly thereafter, the female lays her eggs and glues them to the underside of her abdomen, carrying the fertilised eggs underneath her body for a few months. At the time of hatching, the female coconut crab releases the eggs into the ocean. This usually takes place on rocky shores at dusk, especially when this coincides with high tide. The empty egg cases remain on the female's body after the larvae have been released, and the female eats the egg cases within a few days.
           The larvae float in the pelagic zone of the ocean with other plankton for three to four weeks, during which a large number of them are eaten by predators. The larvae pass through three to five zoea stages before moulting into the post-larval glaucothoe stage; this process takes from 25 to 33 days Upon reaching the glaucothoe stage of development, they settle to the bottom, find and wear a suitably sized gastropod shell, and migrate to the shoreline with other terrestrial hermit crabs. At that time, they sometimes visit dry land. Afterwards, they leave the ocean permanently and lose the ability to breathe in water. As with all hermit crabs, they change their shells as they grow. Young coconut crabs that cannot find a seashell of the right size often use broken coconut pieces. When they outgrow their shells, they develop a hardened abdomen. The coconut crab reaches sexual maturity around five years after hatching.  They reach their maximum size only after 40 to 60 years.
