How Is Food Produced?
Supplementary Notes: (PJ Shlachtman): Food Resources How is Food Produced? What Plants and Animals Feed the World? • 15 plant and 8 animal species supply 90% of our food • wheat, rice and corn provide ~50% of the calories people consume; all three are annuals • 2/3 of the world's people live primarily on grains (rice, wheat and corn) The Two Major Types of Food Production • Industrialized agriculture (high-input agriculture) o uses large amts. of fuel energy, water, commercial fertilizers & pesticides • Plantation agriculture (cash crops) • Traditional subsistence agriculture • Traditional intensive agriculture The Green Revolution (1950-1970) Increased yields per unit of area of cropland Involves three steps 1. developing and planting monocultures of key crops 2. lavishing fertilizer, pesticides and water on crops to produce high yields 3. increasing the intensity and frequency of cropping A second green revolution (1967+) began when fast-growing dwarf varieties of rice and wheat were introduced into developing countries Case Study: Food Production in the U.S. • Production doubled since 1940 • Agribusiness – replacing smaller family farms w/ large corporate farms. • Each US farmer feeds about 140 people How Are Livestock Produced? • 10% of the world's land is suitable for producing crops • 20% is used for grazing cattle and sheep • Developed countries consume >50% of the world's grain • Poor developing countries eat mostly grain and live low on the food chain Traditional Agriculture • Interplanting - simultaneously grow several crops on the same plot of land • Common interplanting strategies: 1. Polyvarietal cultivation 2. Intercropping 3. Agroforestry (alley cropping) 4. Polyculture 1 World Food Problems 1950-1990: • amount of food traded in the world market quadrupled • population growth is outstripping food production • Factors leading to the slowdown in the growth of per capita grain production: 1. -

EENY-170 Ladybirds, Ladybird beetles, Lady Beetles, Ladybugs of Florida, Coleoptera: Coccinellidae1 J. H. Frank R. F. Mizell, III2 Introduction Ladybird is a name that has been used in England for more than 600 years for the European beetle Coccinella septempunctata. As knowledge about insects increased, the name became extended to all its relatives, members of the beetle family Coccinellidae. Of course these insects are not birds, but butterflies are not flies, nor are dragonflies, stoneflies, mayflies, and fireflies, which all are true common names in folklore, not invented names. The lady for whom they were named was "the Virgin Mary," and common names in other European languages have the same association (the German name Marienkafer translates Figure 1. Adult Coccinella septempunctata Linnaeus, the to "Marybeetle" or ladybeetle). Prose and poetry sevenspotted lady beetle. Credits: James Castner, University of Florida mention ladybird, perhaps the most familiar in English being the children's rhyme: Now, the word ladybird applies to a whole Ladybird, ladybird, fly away home, family of beetles, Coccinellidae or ladybirds, not just Your house is on fire, your children all gone... Coccinella septempunctata. We can but hope that newspaper writers will desist from generalizing them In the USA, the name ladybird was popularly all as "the ladybird" and thus deluding the public into americanized to ladybug, although these insects are believing that there is only one species. There are beetles (Coleoptera), not bugs (Hemiptera). many species of ladybirds, just as there are of birds, and the word "variety" (frequently use by newspaper 1. -

In a globalised, market-driven world, it remains at the same time a myth and a marginal phenomenon. Empirically, subsistence agriculture for a long time seemed to be restricted to developing countries, with only a few cases reported in Western Europe (CAILLAVET and NICHELE 1999; THIEDE 1994). Governmental support offered to subsistence agriculture was mainly done through agricultural development policies, the main objective being to have subsistence farmers participate in markets. -
The Jumping Plant-Lice (Hemiptera: Psylloidea) of the Maltese Islands
BULLETIN OF THE ENTOMOLOGICAL SOCIETY OF MALTA (2020) Vol. 11 : 103–117 DOI: 10.17387/BULLENTSOCMALTA.2020.18 The jumping plant-lice (Hemiptera: Psylloidea) of the Maltese Islands David MIFSUD* ABSTRACT. Twenty-one species of jumping plant-lice accommodated in five different families are here recorded from the Maltese Islands in an annotated checklist. The Aphalaridae is represented by four species (Agonoscena targionii (Lichtenstein), Blastopsylla occidentalis Taylor, Colposcenia aliena (Löw) and Glycaspis brimblecombei Moore), of which two (B. occidentalis and G. brimblecombei) are alien species originating from Australia. The Homotomidae is represented by Homotoma ficus (Linnaeus) and Macrohomotoma gladiata Kuwayama, the latter being an alien species originating from the Far East. The Liviidae is represented by Euphyllura olivina (Costa), Diaphorina lycii Loginova and Psyllopsis fraxinicola (Foerster). The Psyllidae is represented by Acizzia uncatoides (Ferris & Klyver), Cacopsylla myrthi (Puton) and C. pyri (Linnaeus), of which Acizzia uncatoides is an alien species originating from Australia. Finally, the most species-rich family is the Triozidae, represented by nine species (Bactericera albiventris (Foerster), B. crithmi (Löw), B. trigonica Hodkinson, Heterotrioza chenopodii (Reuter), Lauritrioza alacris (Flor), Trioza centranthi (Vallot), T. galii Foerster, T. kiefferi Giard and T. urticae (Linnaeus)). For each of the above species, collection data, distribution, host- plant data and other relevant information is provided. Lycium intricatum Boiss. is a new host-plant record for Diaphorina lycii, and Rhamnus lycioides subsp. oleoides (L.) Jahand. & Maire is a new host-plant record for Cacopsylla myrthi. A host- plant shift is documented for Bactericera crithmi, which alternates between Ferula melitensis Brullo et al. in winter and Crithmum maritimum L. -

Buku ini sangat penting dalam bidang pertanian khususnya dalam proses peningkatan produksi pertanian. Masalah-masalah yang sering muncul dan dihadapi dalam budidaya pertanian yaitu semakin banyaknya model pertanian yang monokultur dalam skala yang luas. Model pertanian seperti ini kecenderungan mempunyai keanekaragaman hayati yang rendah sehingga cenderung rentan terhadap serangan organisme pengganggu tanaman (OPT). Populasi OPT pada umumnya lebih banyak dibandingkan dengan populasi musuh alaminya. Solusi untuk mengatasi kondisi agroekosistem dengan keanekaragaman hayati yang rendah yaitu dengan merekayasa agroekosistem semirip mungkin dengan ekosistem alami. Buku ini menjadi salah satu referensi bagi mahasiswa dan masyarakat umum untuk merekayasa sebuah agroekosistem dengan tujuan untuk meningkatkan peran musuh alami sehingga proses keseimbangan ekosistem dapat terwujud. -

Two field experiments have been set up to investigate possibilities for self sufficiency based on an adjusted traditional diet and alternatively based on a vegan diet. The project focuses on the respective land requirements, an adapted choice of crops and the appropriate ecological production methods based on human labour. This report analyses the experiences and results from this year's vegan food plot. Space requirements for self-sufficient production based on a vegan diet are considerably lower than for any diet, which consists of a lot of meat. -

Directions for Long-Term Research in Traditional Agricultural Systems of Micronesia and the Pacific Islands
Micronesica 40(1/2): 63-86, 2008 Directions for long-term research in traditional agricultural systems of Micronesia and the Pacific Islands HARLEY I. MANNER College of Liberal Arts and Social Sciences, University of Guam, UOG Station, Mangilao, Guam 96923 Abstract— Following a review of the major systems of traditional agriculture, this paper briefly considers the role of traditional agriculture in environmental modification, and the related concepts of sustain- ability, agricultural intensification, carrying capacity, biodiversity and agricultural disintensification (abandonment). Research interest in traditional agricultural systems of the Pacific Islands has waned considerably since the 1960s and there are few current studies of these systems in Micronesia. Both species and cultivar diversity of the traditional agricultural systems of the region are high and may contribute significantly to their sustainability. However, there is little ongoing research on the role of biodiversity in these traditional systems. Some reasons for the apparent lack of research in the ecology of traditional agricultural systems are presented. The Pacific-Asia Biodiversity Transect (PABITRA) network emphasizes investigation of the function of biodiversity and the health of ecosystems in the tropical Pacific Islands. Accordingly, PABITRA’s focus should be on long-term monitoring of traditional agricultural systems in order to define their structural and functional characteristics and the relationship between diversity and sustainability. Given the rapid rate of modernization, the documentation of traditional agricultural knowledge and resources is imperative as this knowledge is rapidly being lost. Introduction Traditional agriculture has a profound effect on the biodiversity and landscape ecology of the Pacific Islands. The most viable and sustainable of these traditional systems are those which mimic the structure and function of their corresponding natural ecosystems.
