Subjects: Environmental Economics and Policy

description: The main objective in this paper is to promote thinking on what "sustainable development" or "ecologically sustainable development" means for a small trading country. After a brief acknowledgement of some of the diverse literature on sustainability, there is a consideration of some realities facing a small trading economy. The balance of the paper comprises a discussion of the scope for a small country to enhance sustainability. This is done under several headings, corresponding to different classes of resources. Although some of the discussion in the paper is couched in general terms, much of it is in the context of Australian conditions.
On the relationship between mean observations, spatial averages and the Dyer-Roeder approximation in Einstein-Straus models

description: The redshift and redshift-distance relation in different Einstein-Straus models are considered. Specifically, the mean of these observables along 1000 light rays in different specific models are compared with predictions based on the Dyer-Roeder approximation and relations based on spatial averaging. It is shown that in certain limits, including those studied earlier in the literature, the Dyer-Roeder approximation and relations based on spatial averages agree with each other to a good precision regarding the redshift and redshift-distance relation and make good predictions of the mean of the exact relations. In limits where the two methods disagree, the Dyer-Roeder approximation clearly yields the better approximation of the true mean. This is explained by demonstrating the effect of boundary terms and integrated Sachs-Wolfe contributions but it is pointed out that the result seems to be valid for other Swiss-cheese models as well. Lastly, an expression for the redshift drift in Einstein-Straus models is presented and used for studying the behavior of this quantity in particular Einstein-Straus models.

description: The Painleve test is very useful to construct not only the Laurent series solutions of systems of nonlinear ordinary differential equations but also the elliptic and trigonometric ones. The standard methods for constructing the elliptic solutions consist of two independent steps: transformation of a nonlinear polynomial differential equation into a nonlinear algebraic system and a search for solutions of the obtained system. It has been demonstrated by the example of the generalized Henon-Heiles system that the use of the Laurent series solutions of the initial differential equation assists to solve the obtained algebraic system. This procedure has been automatized and generalized on some type of multivalued solutions. To find solutions of the initial differential equation in the form of the Laurent or Puiseux series we use the Painleve test. This test can also assist to solve the inverse problem: to find the form of a polynomial potential, which corresponds to the required type of solutions. We consider the five-dimensional gravitational model with a scalar field to demonstrate this.

Fifth Annual Performance Survey of Reinforced Concrete Pipe Culverts
Creators: name: Hughes, Ronald D.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1965
Subjects: subject: Transportation Engineering

description: For many years, engineers have sought a simplified method for determining the strength requirements for underground conduits under various conditions of bedding and backfilling. Methods of installation and the general lack of a uniform design criteria tended to restrict the usefulness of rigid pipe culverts. With the advent of the interstate construction program and the increased mileage of highways meeting high design standards, the number of pipe culverts installed under high fills was significantly increased. This, of course, accented even more so the need for a more straightforward criteria for design and installation of rigid pipe in order that maximum utilization of pipe strengths might be realized and that settlement in the roadway surface near the installation might be minimized. In an effort to satisfy the needs for a simplified design method for rigid pipe, the Bureau of Public Roads in cooperation with Professor M. G. Spangler of Iowa State College and the American Concrete Pipe Association initiated a study of reinforced concrete pipe design and installation procedures. As a result of this study, a stylized, rational criterion was developed and distributed to the various state highway agencies as B. P. R. Circular Memorandum 22-40, dated April 4, 1957.
A NEW SUBGENUS AND TWO NEW SPECIES OF TRECHUS FROM ETHIOPIA (Coleoptera, Carabidae)

description: Two new species of Trechus from the Oromia Province (Ethiopia) are described in the present note. In the first part we describe Archeotrechus, a new microphtalmic Trechus, characterized by the dilation of only the first tarsal segment in males and by the aedeagus with the dorsal part amost completely divided into two lobes: a sclerified connection exists only in the region of the basal ostium. To this subgenus we ascribe the new species Trechus (Archeotrechus) relictus, from the area of Mt. Sgona (Batu), of yellow-brown colour, rather flattened, with non sinuate pronotum and blunt fore and hind angles; two discal setae in the third stria. The aedeagus is much elongated, with a spherical apical button, copulatory piece triangular, lanceolate, with a sharp apex, little sclerified and very simple, typical of ancestral forms, like for instance Minitrechus Vigna Taglianti & Magrini, 2009. The female gonostyli, short and curved, bear at the apex two big setae on the inner edge. In the second part of the note we describe Trechus (s. str.) oromiensis, a new species of bipartitus Group (sensu novo), characterized by the presence of only one discal seta on elytra and by peculiar features of the aedeagus.

description: Clearly, the question which is the workshop title permits of no single simple answer. This paper addresses it in the particular context of taxation. The argument is that in this context the sustainability debate seems to have had rather little effect on economists' thinking and policy advice. While it is true that taxation is looked upon more favourably than some alternative instruments for environmental policy implementation, there does not appear to have been much in the way of thinking about. or policy advice on, taxation per se in the context of concern for sustainability promotion.
A generalisation of the mass-sheet degeneracy producing ring-like artefacts in the lens mass distribution

description: The inversion of a gravitational lens system is, as is well known, plagued by the so-called mass-sheet degeneracy: one can always rescale the density distribution of the lens and add a constant-density mass-sheet such that the, also properly rescaled, source plane is projected onto the same observed images. For strong lensing systems, it is often claimed that this degeneracy is broken as soon as two or more sources at different redshifts are available. This is definitely true in the strict sense that it is then impossible to add a constant-density mass-sheet to the rescaled density of the lens without affecting the resulting images. However, often one can easily construct a more general mass distribution -- instead of a constant-density sheet of mass -- which gives rise to the same effect: a uniform scaling of the sources involved without affecting the observed images. We show that this can be achieved by adding one or more circularly symmetric mass distributions, each with its own center of symmetry, to the rescaled mass distribution of the original lens. As it uses circularly symmetric distributions, this procedure can lead to the introduction of ring shaped features in the mass distribution of the lens. In this paper, we show explicitly how degenerate inversions for a given strong lensing system can be constructed. It then becomes clear that many constraints are needed to effectively break this degeneracy.

description: We provide strong evidence that the asymptotically free (1+1)-dimensional non-linear O(3) sigma model can be regularized using a quantum lattice Hamiltonian, referred to as the "Heisenberg-comb", that acts on a Hilbert space with only two qubits per spatial lattice site. The Heisenberg-comb consists of a spin-half anti-ferromagnetic Heisenberg-chain coupled anti-ferromagnetically to a second local spin-half particle at every lattice site. Using a world-line Monte Carlo method we show that the model reproduces the universal step-scaling function of the traditional model up to correlation lengths of 200,000 in lattice units and argue how the continuum limit could emerge. We provide a quantum circuit description of time-evolution of the model and argue that near-term quantum computers may suffice to demonstrate asymptotic freedom.

description: Nella presente nota viene elevato a livello specifico Trechus nicoleae Moncoutier, 1986, considerato in passato come sottospecie di T. liguricus Jeannel, 1921 (Moncoutier 1986, 1990) o di T. putzeysi Pandellé, 1867 (Coulon 2004). Esso risulta ben distinguibile dagli affini T. putzeysi (con il quale convive in parte dell’areale) e T. liguricus, per la diversa morfologia dell’organo copulatore maschile: le differenze di morfologia esterna non vengono considerate un carattere diagnostico costante e affidabile. Viene confermato il nomen invalidum per Trechus [liguricus] nicolianus Moncoutier, 1990, e vengono confermate le sinonimie con le rispettive forme tipiche di T. putzeysi vesulinus Jeannel, 1927 (Vigna Taglianti 1993) e T. liguricus mancinii Jeannel, 1921 (Magrini 1990).

We characterize the state of the emitted atom beams by observing strong number squeezing up to -10 dB in the correlated two-particle modes of emission. We furthermore demonstrate genuine two-particle interference in the normalized second-order correlation function $g^{(2)}$ relative to the emitted atoms.

description: In the Hubble Ultra Deep Field (HUDF) an abundance of galaxies is seen with a knot at one end plus an extended tail, resembling a tadpole. These "tadpole galaxies" appear dynamically unrelaxed--presumably in an early merging state--where tidal interactions likely created the distorted knot-plus-tail morphology. Here we systematically select tadpole galaxies from the HUDF and study their properties as a function of their photometric redshifts. In a companion HUDF variability study, Cohen et al. (2005) revealed a total of 45 variable objects believed to be Active Galactic Nuclei (AGN). Here we show that this faint AGN sample has no overlap with the tadpole galaxy sample, as predicted by theoretical work. The tadpole morphology--combined with the lack of overlap with the variable objects--supports the idea that these galaxies are in the process of an early-stage merger event, i.e., at a stage that likely precedes the "turn-on" of any AGN component and the onset of any point-source variability.

La specie risulta affine, per i caratteri dell’edeago e della lamella copulatrice, ad alcune specie del Sud dell’isola, quali T. pellita Leo, Magrini & Fancello, 2005 e T. regina Leo, Magrini & Fancello, 2005, ma se ne differenzia nettamente per alcuni caratteri peculiari: in primo luogo per l’habitus molto stretto e allungato, “cliviniforme”, con pronoto che presenta un valore PMW/PL di solo 0,93, uno dei più bassi all’interno del genere, ed elitre parallele ai lati per buona parte della loro lunghezza, con denticolazione marginale piuttosto ridotta, di soli 10-11 denticoli presenti nei 2/3 basali dell’elitra. L’endofallo presenta una lamella copulatrice simile a quella delle due specie citate, ma molto più sottile in visione laterale e fornita di una seconda lamina dorsale, ampia e meno sclerificata, non presente negli altri due taxa. La nuova specie, per i suoi peculiari caratteri morfologici, si pone per ora in posizione isolata rispetto ai gruppi di specie già noti, e presenta caratteristiche più tipiche di un abitatore di ambiente endogeo o sotterraneo superficiale che non di un elemento proprio di ambiente sotterraneo profondo.

description: As an attractive candidate for dark matter, the primordial black holes (PBHs) in the mass range ($10^{15} \sim 10^{16}$)$\mathrm{g}$ could be detected via their Hawking radiation, including neutrinos and antineutrinos of three flavors. In this paper, we investigate the possibility to constrain the PBH as dark matter by measuring (anti)neutrino signals at the large liquid-scintillator detector of Jiangmen Underground Neutrino Observatory (JUNO). Among six available detection channels, the inverse beta decay $\overlineν^{}_e + p \to e^+ + n$ is shown to be most sensitive to the fraction $f^{}_{\rm PBH}$ of PBHs contributing to the dark matter abundance. Given the PBH mass $M^{}_{\rm PBH} = 10^{15}~{\rm g}$, we find that JUNO will be able to place an upper bound $f^{}_{\rm PBH} \lesssim 3\times 10^{-5}$, which is 20 times better than the current best limit $f^{}_{\rm PBH} \lesssim 6\times 10^{-4}$ from Super-Kamiokande. For heavier PBHs with a lower Hawking temperature, the (anti)neutrinos become less energetic, leading to a relatively weaker bound.

The present collection of turtles from the Judith River Formation consists of isolated and fragmentary carapace and plastron plates. These are in most instances inadequate for generic identification and only two genera have been distinguished, namely Trionyx and Basilemys. Baenid turtles may also be present but the material is too fragmentary for identification. The chelonians previously reported from the Judith River Formation are Baena, Polythorax, Plastomenus, and possibly Adocus (see Hay, 1908).

description: We present an analytic theory for the optical properties of ellipsoidal plasmonic particles covered by anisotropic molecular layers. The theory is applied to the case of a prolate spheroid covered by chromophores oriented parallel and perpendicular to the metal surface. For the case that the molecular layer resonance frequency is close to being degenerate with one of the particle plasmon resonances strong hybridization between the two resonances occur. Approximate analytic expressions for the hybridized resonance frequencies, their extinction cross section peak heights and widths are derived. The strength of the molecular - plasmon interaction is found to be strongly dependent on molecular orientation and suggest that this sensitivity could be the basis for novel nanoparticle based bio/chemo-sensing applications.

description: Nel presente lavoro sono riportate le attuali conoscenze faunistiche riguardanti i Coleoptera (Carabidae, Chrysomelidae) e i Lepidoptera (Hesperioidea, Papilionoidea) della Valle della Nava (Provincia di Lecco, Italia). Viene documentata l’attuale situazione ambientale in un’area ancora scarsamente soggetta alla pressione antropica, tramite lo studio delle comunità di questi gruppi tassonomici. Indagini analoghe hanno dimostrato in più di un caso di essere adatte ad evidenziare gli effetti dell’alterazione ambientale di un determinato territorio, consentendo di ricavare utili informazioni per la gestione degli habitat in esso presenti (Thiele 1977; Brandmayr 1983; Pizzolotto 1994, Balletto et al. 1982a, 1982b). I dati provengono da 7 anni di ricerche entomologiche effettuate con svariate tecniche di raccolta, a cui si aggiungono alcuni dati inediti ricavati dall’esame della collezione Brivio conservata presso il Museo Civico di Storia Naturale di Milano. È stata rilevata la presenza di 180 specie (68 di Carabidae, 72 di Chrysomelidae, 40 di Lepidoptera Hesperioidea, Papilionoidea). Considerata la piccola dimensione dell’area di studio (circa 75 ettari) i dati ottenuti sono particolarmente indicativi e interessanti. Vengono infine esposte alcune considerazioni zoogeografiche e ecologiche.

Subjects: Agricultural Finance

description: Although credit can be directed with sufficient facility toward some economic activities, the same cannot be said about agriculture, first because there are thousands of clients and secondly, most of them do not meet the requirements for obtaining a loan. Moreover, they do not know how to utilize credit and frequently they do not accept the general conditions that the credit institutions establish. Unfamiliarity with the sources of funds is another problem. Therefore, if credit does not accompany other complementary services, like technical assistance for example, the farmers present low modernization indexes, and productivity levels are not very different in relation to those who do not use credit. Given the importance that agricultural credit has for the Costa Rican economy and its role in the country's development, it is necessary to examine the agricultural credit situation with emphasis on the last eight years. For this reason the method of analysis employed in this study is descriptive and diagnostic.

description: The main difficulties in constructing a viable early Universe bouncing model are: to bypass the observational and theoretical \emph{no-go} theorem, to construct a stable non-singular bouncing phase and perhaps, the major concern of it is to construct a stable attractor solution which can evade the BKL instability as well. In this article, in the homogeneous and isotropic background, we extensively study the stability analysis of the recently announced viable non-minimal bouncing theory in the presence of an additional barotropic fluid and show that, the bouncing solution remains stable and can evade BKL instability for a wide range of the model parameter. We provide the expressions that explain the behavior of the Universe in the vicinity of the required fixed point i.e., the bouncing solution and compare our results with the minimal theory and show that ekpyrosis is the most stable solution in any scenario.

description: We consider a strongly correlated ladder with diagonal hopping and exchange interactions described by $t-J$ type hamiltonian. We study the dynamics of a single hole in this model in the presence of a static non-magnetic (or magnetic) impurity. In the case of a non-magnetic (NM) impurity we solve the problem analytically both in the triplet (S=1) and singlet (S=0) sectors. In the triplet sector the hole doesn't form any bound state with the impurity. However, in the singlet sector the hole forms bound states of different symmetries with increasing $J/t$ values. Binding energies of those impurity-hole bound states are compared with the binding energy of a pair of holes in absence of any impurity. In the case of magnetic impurity the analytical eigenvalue equations are solved for a large (50 X 2) lattice. In this case also, with increasing $J/t$ values, impurity-hole bound states of different symmetries are obtained. Binding of the hole with the impurity is favoured for the case of a ferromagnetic (FM) impurity than in the case of antiferromagnetic (AFM) impurity. However binding energy is found to be maximum for the NM impurity. Comparison of binding energies and various impurity-hole correlation functions indicates a pair breaking mechanism by NM impurity.

description: Nella presente nota viene descritto Otiorhynchus (Lixorrhynchus) milazzoi n. sp. della Sicilia occidentale: di questa specie viene fornita solo una descrizione incompleta per l’assenza degli organi genitali nell’unico esemplare noto e nei resti raccolti. Il nuovo taxon, il primo per la Sicilia, amplia notevolmente verso Sud l’areale di questo sottogenere. Nel lavoro viene ribadita anche la validità generica di Ioniorhynchus Magrini, Meoli & Abbazzi, 2005 (ingiustamente considerato, a nostro avviso, sottogenere di Otiorhynchus da Osella, 2008a), per le nette differenze del genitale maschile nei confronti di Otiorhynchus Germar, 1822.

description: The agricultural sector in Costa Rica, as in many other developing countries, has been playing an important role in the economic development of the country. This sector presently contributes approximately 30 percent of the gross national product, generates 69 percent of the total foreign exchange, and employs 47 percent of the total labor force in the country. Nevertheless, full use of labor is reflected in the form of open or disguised unemployment in the agricultural sector. There are no reliable estimates of the magnitude of these forms of unemployment, but it is likely that underemployment or migration might have increased. This underemployment of human resources has stimulated a greater migration towards the main cities, causing a disproportionate growth of these urban centers. The disproportionate growth of the urban centers has brought about a sharp increase in the urban centers has brought about a sharp increase in the urban demand for food, which is exerting pressure on the existing marketing channels. In order to avoid inflationary pressures on the economy, it is necessary that increases in the demand for food products be accompanied by a parallel growth in the supply of agricultural products, which will require a matching expansion in the marketing channels.

description: Orarabion dominici n. gen n. sp. della sottotribù Melambiina viene descritto su esemplari provenienti dal’Oman settentrionale. Il nuovo genere è caratterizzato principalmente dal corpo attero, massiccio, la taglia relativamente grande, le elitre con strie sottili ed interstrie piane, le protibie con margine esterno largamente arrotondato ed apice svanito, l’organo copulatore maschile relativamente allungato con lunga e fitta pubescenza all’apice dei parameri. La localizzazione geografica del nuovo genere è estremamente eccentrica rispetto all’areale dei restanti generi Paleartici della sottotribù cui sembra essere più affine.

description: We quantize three Friedmann-Robertson-Walker models in the presence of a negative cosmological constant and radiation. The models differ from each other by the constant curvature of the spatial sections, which may be positive, negative or zero. They give rise to Wheeler-DeWitt equations for the scale factor which have the form of the Schroedinger equation for the quartic anharmonic oscillator. We find their eigenvalues and eigenfunctions by using a method first developed by Chhajlany and Malnev, and use the eigenfunctions in order to construct wave packets for each case and evaluate the time-dependent expected value of the scale factors. We find for all of them that the expected values of the scale factors oscillate between maximum and minimum values. Since the expectation values of the scale factors never vanish, we conclude that these models do not have singularities.

Subjects: Resource /Energy Economics and Policy

description: Energy use and it's availability, now and in the future, have been of increasing concern as the decade of the 1970's elapsed and the 1980's begin. This paper describes a farm energy audit project that addressed this concern of energy use by farms in Michigan. The objectives of this paper are fourfold. First, is documentation of the Michigan Farm Energy Audit Study. This involves the step-by-step procedure as to formulation and development of the project. The second objective is to report the results of Phase I of the project. The third objective is to evaluate the feasibility of going from a pilot program to a more generalized system. This evaluation includes specification of the changes needed to expand the project to a more general system. Finally, the fourth objective is to evaluate the potential use and benefits of the project for farmers.

description: How do dairy farms manage their human resources and how can the farms achieve competitive advantage through the human resource management (HRM) function? This inductive study of six dairy farms in Michigan explores those two questions using the resource-based theory (RBT) framework. Onsite interviews were conducted with 7 managers, 6 herdsmen and 7 non-supervisory employees. An interpretive research paradigm was used for both within case and between case analyses. Drawing insights from the RBT which postulates that valuable, rare, inimitable, and non-substitutable resources confer competitive advantage, results from this study indicate that dairy farms have the potential to achieve competitive advantage through their HRM function. While there are similar HRM practices across cases like recruiting and selection, the integration of specific HRM practices with the organizational culture (values of farm managers, relationships based on kinship and friendship ties) and resource endowment leads to different organizational outcomes (costly mistakes by employees, voluntary turnover and termination) Finally, based on propositions developed from this study and RBT literature, a conceptual framework is proposed to guide future research on how to empirically test the relationship between the HRM function and performance of farm enterprises to ascertain whether human resources are a potential source of sustained competitive advantage.
Quantification and Correction of Systematic Errors Due to Detector Time-Averaging in Single-Molecule Tracking Experiments

description: Single-molecule tracking is a powerful way to look at the dynamic organization of plasma membranes. However, there are some limitations to its use. For example, it was recently observed, using numerical simulation, that time-averaging effects inherent to the exposure time of detectors are likely to bias the apparent motion of molecules confined in microdomains. Here, we solve this apparently limiting issue analytically. We explore this phenomenon by calculating its effects on the observed diffusion coefficients and domain sizes. We demonstrate that the real parameters can be easily recovered from the measured apparent ones. Interestingly, we find that single-molecule tracking can be used to explore events occurring at a timescale smaller than the exposure time.

description: During entomological research carried out in the Pontine Islands (central Italy, Latium, Latina province), Dapsa gemina Audisio & De Biase, 1996 (Coleoptera, Endomychidae), previously known only from coastal areas of NE Algeria, has been recorded in Italy and in Europe for the first time. This new record suggested the authors to shortly discuss the possible scenario of a relatively recent, late Pleistocene passive transportation of Dapsa gemina and of the related D. obscurissima Pic, 1904 (sharing a very similar disjunct geographic distribution) by marine drift of masses of vegetal debris from North Africa.

description: ($ABRIDGED$) We probe the physical properties and large-scale environment of radio AGN in the faintest FR population to-date, and link them to their radio structure. We use the VLA-COSMOS Large Project at 3 GHz, with resolution and sensitivity of 0".75 and 2.3 $μ$Jy/beam, respectively, to explore the FR dichotomy down to $μ$Jy levels. We classify objects as FRIs, FRIIs or hybrid FRI/FRII based on the surface-brightness distribution along their radio structure. Our control sample is the jet-less/compact radio AGN (COM AGN) which show excess radio emission at 3 GHz VLA-COSMOS exceeding what is coming from star-formation alone; this sample excludes FRs. Largest angular projected sizes of FR objects are measured by a machine-learning algorithm and also by hand, following a parametric approach to the FR classification. Eddington ratios are calculated using scaling relations from the X-rays, while we include the jet power by using radio luminosity as a probe. We investigate their host properties (star-formation ratio, stellar mass, morphology), and we explore their incidence within X-ray galaxy groups in COSMOS, as well as in the density fields and cosmic-web probes in COSMOS. Our sample is composed of 59 FRIIs, 32 FRI/FRIIs, 39 FRIs, and 1818 COM AGN at 0.03 $\le z \le$ 6. FR objects have on average similar radio luminosities ($L_{\rm 3~GHz}\rm \sim 10^{23}~W~Hz^{-1}~sr^{-1}$), spanning a range of $\rm 10^{21-26}~W~Hz^{-1}~sr^{-1}$, and lie at a median redshift of $z ~\sim ~1$. FRs reside in their majority in massive quenched hosts ($M_{*}~> 10^{10.5} M_{\odot}$), with older episodes of star-formation linked to lower X-ray galaxy group temperatures, suggesting radio-mode AGN quenching. Irrespective of their radio structure, FRs and COM AGN are found in all types and density environments (group or cluster, filaments, field).

PROSPECTS AND PROBLEMS OF WHEAT SURPLUS IN WEST PAKISTAN DURING 4TH FIVE YEAR PLAN

Subjects: Crop Production/Industries

description: The area now constituted as West Pakistan was considered the granary of British India. Despite this, the area has been troubled by food problems during many of the years since independence. A major reason is the high rate of population growth. As the National Government improved the public health facilities, after independence, the death rate declined but the birth rate remained high. The population in 1931, of areas which came to be West Pakistan, was 23.6 million persons, with a growth rate of 1.2 percent; in 1941 it was 28.3 million and growth at 2.0 percent; in 1951 it was 33.7 million and 1.9 percent. For 1966 the estimate is 48.8 million, a doubling of the population in 35 years, implying a doubling of food requirements without any improvement in diet. But in addition, developmental activities have increased the level of income, thus increasing the demand for food. In West Pakistan, both factors substantially increased the demand for wheat, as it is the major component of the diet of the people. As increasing demand was not matched with an expanding supply, chronic food problems occurred, and the Government had to resort to imports, a burden on the meager foreign exchange resources of the county. Realizing the impact of this wheat shortage on the whole economy, the Third Plan laid down the objective to achieve self-sufficiency in foodgrains. It suggested both extensive and intensive methods to increase foodgrains production, with wheat as the most prominent crop in West Pakistan.

description: Lesotho is largely agrarian. More than 90 percent of the Basotho population lives in rural areas. Agriculture provides an important source of income for over 50 percent of the rural population and is the largest contributor to GDP. Apart from migrant labour in the Republic of South Africa (RSA) and limited work in administration and commerce in the few urban centers, there are few employment opportunities other then agriculture. Under production of maize coupled with a growing population has lead to great shortages of maize in Lesotho. The hunger and nutritional problems associated with the maize shortage problem prompted the Government of Lesotho to set out self-sufficiency goals, which if met would help solve the maize shortage problem. In view of the great maize shortage that Lesotho is faced with, the intent of this paper is to (1) investigate the most important determinants of maize supply; (2) make supply and demand projections of maize to 1985; and (3) to formulate alternatives which can be used by decision makers in setting policy.
