Abstract The success in the seed production of the sand goby (Oxyeleotris marmorata) has contributed to the protection of natural resources and the availability of seed for aquaculture. About 30-50 million sand goby fingerlings are produced in hatcheries for domestic and export markets every year. Grow-out production systems of sand goby developed in the 1990s. It helped to increase the incomes of many fish farmers and contributed to the country's foreign exchange earnings. Constraints to hatchery-produced seed for grow-out have resulted in difficulties for sand goby seed producers. Hatchery-produced seed commands a higher price than wild seed and thus is not able to completely replace the natural seed supply. However, wild seed is of uneven size and capture methods are not standardized, resulting in the fish body being easily scratched, leading to disease and mortality. The fish is sensitive to changes in environmental conditions and vulnerable to diseases which are difficult to treat. The market for this species is also limited.

The rapid changes that societies have gone through in the last few decades have led to the increase in the prevalence of malnutrition in all its forms and to the degradation of natural resources and the environment. The change in the dietary habits and production systems are responsible for much of this change. Some territorial diets have been shown as potentially capable of reversing these trends by positively contributing to the health of people and the environment such as the Mediterranean Diet and the New Nordic Diet. In this paper, we review the contribution of these 2 diets to health and nutrition and to environmental, sociocultural, and economic sustainability proposing pertinent indicators. Learning from a culturally established diet and a constructed one, tradeoff could be reached to ensure better health and sustainability outcomes. Strong factors for achieving this goal lie in building on the sociocultural appropriation of diets, having the proper tools and indicators, investing in cross-sector collaboration and policy coherence, and having the necessary political support to push the agenda of sustainability forward.

Health concerns have gained proportional attention among the peoples and governments of the world. Or at least it looks that way! Terms like Cholesterol, Triglyceride, Diabetes, Tumor, Benign, Malignant are all too familiar to many. Health food and diets have mushroomed into large money making industries. I wonder if they are life-saving too! Furthermore, it is becoming more difficult to separate between health and environment. Hence, the deterioration of health conditions all over the world is closely associated to impairments in environmental conditions and natural resources.

Informal Seed Supply

Formal and informal seed supply systems of rice (Jumla, Bara and Kaski), finger millet and taro(Kaski) were studied in three ecosites of Nepal during 1999-2001 to understand the processes ofseed flow, seed production, seed selection and storage systems. A survey was conducted at 48 to96 households. Informal seed supply was the only system in Jumla and Kaski and formal systemexisted only in Bara. The main sources of seed were farmer's own saved seed (67-91%), seedfrom neighbors and relatives. Exchange of germplasm was the main basis of fulfillment fromother sources. All farmers obtained seed from their own village, while farmers introducedmaterials occasionally from outside village. Most of the farmers followed seed selection beforeor after crop harvest. Rice field selection and plant selection based on a fixed set of criteria wasthe common practice. Non lodged plants with more grain per panicle, bold grains, well-maturedand uniform plants, long panicle, true to type, good looking grains, free from diseases andinsects were the main rice seed selection criteria. All farmers from both sites stored rice seeds bylocal methods in the locally available containers. Mor and Mudkothi are the special strawcontainers to store rice seed in Bara. Dhara is a special mud structure used to store rice seeds inJumla. Finger millet seed supply system was mostly similar to that of rice seed system. Ninetyone percent farmers saved seed for their own use; however, many of them changed finger milletseeds lots or varieties regularly for their particular plot. Ears selection during harvest by setcriteria for seed purpose was the common practice. Farmers stored finger millet seed carefully insmall locally available containers and tried their best to maintain the quality of seed duringdifferent stage of seed production. Taro has diverse planting materials: cormels, corms witheyes, suckers and corm with small cormels. Taro planting materials management is totallyinformal and almost 89% farmers saved these materials for their use and replaced them mostlyafter 3 years. Farmers had fixed criteria of corms and cormels selection for planting purpose andfocus and more on disease free. Storage of planting materials was locally by using localmaterials and methods. Understanding of seed system in various crops helps to developconservation strategy.Key words: Seed flow; seed production; seed selection; seed storage; seed systemDOI: 10.3126/narj.v6i0.3343Nepal Agriculture Research Journal Vol.6 2005 pp.39-48

The paper describes a method for creating new and increasing the yield of existing varieties based on analysis variability elements of rice varieties yield structure under influence of environmental conditions. Seeding rates are used as a source of variability. Following trait are analyzed: seeds field germination, survival plants before harvesting, total tillering of plants, realization of total tillering, graininess of panicle, fertility of spikelets, weight of 1000 grains. Based on analysis, through onnections conjugated elements, the optimal values of elements structure of yield are determined, at which it takes the maximum value. Based on a set of optimal values, theoretical model of studied rice variety is being developed. Then, according to panicles selected in variety, single-row plots are sown for further propagation, rows with parameters of the yield structure elements set same with model of variety are selected, which makes it possible to increase the yield of Mavr rice variety by 39.18 centners / ha or 45.61%.

Poultry Nutrition

SummaryIn the context of mismanagement of natural resources going with an increasing consumption of protein from animal origin through the world population, one major challenge for the future in animal nutrition is the improvement of its efficiency and hence sustainability. Up to now, a broad range of methods like feed additives or technological treatments have been available to improve the efficiency or the production of pig-derived and poultry-derived food and hence the sustainability in pig and poultry nutrition. Nevertheless, the exact knowledge of the mode of action of these tools is a prerequisite for their successful application. Furthermore, information concerning their impact on the nutrient availability of the different feedstuffs is of great importance, in order to formulate diets that cover the animals’ requirements. Diets covering the animals’ performance level ovoid undersupplies, which can lead to health problems on the on hand, on the other hand the emissions of nitrogen are kept as low as possible.As a result, the consumption of natural resources like grains can be considerably reduced and the substitution of regional by-products from the feed and food processing industry like wheat bran, dried distillers grains with solubles or rapeseed meal can be dramatically enhanced in diets for monogastric animals, thus contributing to more sustainable livestock production. By improving the efficiency of the production of animal-derived food, the term “sustainable’’ remains highly significant. Increasing efficiency plays an important role in ensuring that the resources required for pig and poultry nutrition are foreseeably available. Currently, there is a combination of different tools like feed additives or technological feed treatments the most promising way of improving sustainability in pig and poultry production systems.

Pangasius Bocourti

Abstract The two pangasiid catfish, Pangasius bocourti and P. hypophthalmus, are widely cultured in the Mekong Delta, Vietnam. However, seed supply until recently was dependent on fry and fingerlings caught from the Mekong River. In 1994, a research programme was carried out on artificial seed production of these two species in captive conditions. In 1995, about 30,000 fingerlings were first produced in An Giang and Can Tho provinces and a proper technique of induced breeding, progressive human chorionic gonadotropin (hCG) treatment, was determined. This technique, involving two steps of hCG injections, successfully induced ovulation in 66% of 67 treated females of P. bocourti. Application of this technique to other pangasiid catfish species such as P. conchophilus, P. hypophthalmus, P. mekongensis, and P. larnaudii also resulted in breeding success. Research on larval rearing has also been conducted to improve the growth and survival of pangasiid larvae. Extension of research findings of induced breeding and larval rearing has allowed mass seed production of pangasiid catfish in the Mekong Delta.

For most of the colonial period, the Codrington family had exclusive control over the island of Barbuda. Deploying the labor of enslaved African workers, they developed the island into an important source of food and other supplies to provision their sugar plantations on nearby Antigua. This chapter examines how Barbuda’s natural resources, built landscape, and labor system were all directed toward that purpose. In particular, it compares the Codringtons’ management strategies with those of Samuel Martin and William Byam, who sub-leased the island from 1746 to 1761. In addition, Anderson argues that enslaved people on Barbuda experienced a unique form of bondage geared toward herding and cultivation of food crops rather than sugar production. It also examines how the particular environmental conditions on Barbuda both offered opportunities and presented challenges for the people lived and worked there.

In India the potential of tourism sector is considerable in terms of earning foreign exchange. That is why the government has initiated many programmes and schemes to attract foreign tourists. It has also given a rise to the allied industries to earn profits and diversify may it be hotel industry or aviation sector. As the means of communication are developing and the countries are becoming more open and globalised the tourism industry has got new impetus and dimensions. The spread of education and the development of internet have widened the scope of this industry. This new trend has made the tourism industry a very potential industry in many terms for a developing nation like India. But on the same hand it has posed a great threat to the natural resources also and the stakeholders involved in this sector has started responding to such initiatives through CSR measures. For measuring such initiatives no specific parameters have been defined and they are subjective to a great extent. Therefore a need arises to analyse such initiatives and their growing need for creating sustainability.
