Production Problems

The climate of Kuwait can be characterized as hot (maximumin excess of 45°C), and dry during the summers (May to October), with high evaporation (16 mm/d). Night-time temperatures also remain relatively high during these summer months. Rainfall over the course of the year is very low, usually being limited to less than 100 mm, which falls primarily during the winter months. Likewise, while the country's sand and dust storms occur primarily during the summer months, there may be occasional flurries at almost any time during the year, causing major additional problems with unprotected production of sensitive food crops, like strawberries. Water is also one of the country's most limiting resources, with all ground-water being highly brackish. Strawberry production, on a commercial basis is a relatively new development in Kuwait. Pre-war production (under protected and unprotected environments) had increased to over 125 tons, on approximately 5 ha of land, providing about 75% of the then existing demand. Strawberry growers set their plants in November and harvest fruit in May. If production could be maintained on a year round basis, at high quality levels, demand would presumably also be significantly higher. While yields had increased to about 25 tons per hectare, production problems include pests (including aphids), cultural practices and adapted cultivars. Current and planned work will be discussed.

History Of

Although Japan had its own distinctive ‘pre-history’ of cultural studies, which produced some excellent research on popular culture, which can be traced back to the 1920s, the current state of cultural studies has been criticized by conventional mainstream academics; whereas the younger generation has been attracted by cultural studies as a new academic trend. An important new development in cultural studies in Japan is Cultural Typhoon. This new movement seeks to avoid institutionalization and create an alternative academic public sphere alongside broadened cultural practices, social activities and political interventions. Cultural studies in Japan can be seen as a part of a new diversity in cultural studies, which has some potentialities to move beyond the academy and open new dialogical spaces for communication and cultural intervention.

Production Problems

Farmers are looking for new crops to grow to diversify their farms and increase profitability. Medicinal herbs are often of interest because they are generally perceived as being easy to grow, in high demand, return good prices, and serve as useful rotational crops. In reality, most farmers who have not previously grown medicinal herbs do not understand the global herb market. They do not know how to find a buyer or which herbs to grow. To help growers produce and market medicinal herbs, we initiated the Medicinal Herbs for Commerce Project. We also conducted studies on production problems for a variety of herbs. An issue that should be addressed is that there are hundreds of medicinal herbs in commerce and it is impossible for a small number of research programs to independently answer all the questions that are being asked by the industry. Developing a consortium of researchers around the world to coordinate efforts on how best to grow and process medicinal herbs and to create a database of information for farmers and agricultural advisors would be a great service for this industry.

Most of the points raised by the Panel members, Drs. Roger Revile, Harold Thomas and Robert Dorfman, have been answered in the comment by Dr. Frank M. Eaton. Dr. Nazir Ahmad has further elaborated some of the issues involved. The author will confine his remarks to two basic issues, namely, pumping of water for irrigation purposes in the non-saline high quality ground¬water areas in the Northern Zone of the Indus Plain and provision of horizontal sub-surface drainage facilities in areas where the groundwaters are saline and unfit for irrigation use. The author is happy to note that the Panel members acknowledge the significant contribution made by private tubewells to the productivity of agri¬culture in West Pakistan. The author agrees with the Panel members that private tubewells will be developed mainly in areas that have adequate supplies of high quality groundwater and not in areas where the groundwater is too saline to be applied to land without dilution with canal water. Ina previous article, the author proposed that horizontal sub-surface drain¬age facilities should be provided in the saline groundwater areas [5, pp.387-395]. The Panel members do not agree with this and propose instead deep tubewells for irrigation as well as for drainage purposes. They suggest that with the use of deep tubewells and canal water the salt be flushed out of the root zone and washed downward with recycled pumped water to be stored underground.

Ground Water Contamination

There are approximately 17,000 acres of fresh market vegetables and potatoes being produced on Long Island where irrigation is a routine agricultural production practice. Irrigation water is obtained from individual wells which pump water from an extensive underground aquifer. Although the quantity of water available for irrigation is not limited at present and will not be in the foreseeable future, the combination of agricultural practices, sandy soils and low soil pH's have had an impact on water quality. Certain pesticides move easily through the porous Long Island soils and are not quickly broken down at the naturally low pH levels of these soils. The use of Temik (aldicarb) for potato production resulted in ground water contamination with this chemical and spurred action by horticultural researchers and county and state agencies to define the scope of, and provide a potential solution for, contamination of Long Islands ground water. Thus, considerable effort has been expended on research and implementation programs to prevent ground water contamination with agricultural chemicals. Much of this effort has involved attempts to alter cultural practices, such as irrigation and pesticide application methods in order to decrease the potential for leaching of contaminants into the ground water. In addition, alternate crops have been considered which may require less irrigation and fewer pesticides than those traditionally grown. Specific research projects and government agency policies pertaining to agricultural water usage on Long Island will be discussed.

ABSTRACT Biological soil crusts (biocrusts) are slow-growing, phototroph-based microbial assemblages that develop on the topsoils of drylands. Biocrusts help maintain soil fertility and reduce erosion. Because their loss through human activities has negative ecological and environmental health consequences, biocrust restoration is of interest. Active soil inoculation with biocrust microorganisms can be an important tool in this endeavor. We present a culture-independent, two-step process to grow multispecies biocrusts in open greenhouse nursery facilities, based on the inoculation of local soils with local biocrust remnants and incubation under seminatural conditions that maintain the essence of the habitat but lessen its harshness. In each of four U.S. Southwest sites, we tested and deployed combinations of factors that maximized growth (gauged as chlorophyll a content) while minimizing microbial community shifts (assessed by 16S rRNA sequencing and bioinformatics), particularly for crust-forming cyanobacteria. Generally, doubling the frequency of natural wetting events, a 60% reduction in sunlight, and inoculation by slurry were optimal. Nutrient addition effects were site specific. In 4 months, our approach yielded crusts of high inoculum quality reared on local soil exposed to locally matched climates, acclimated to desiccation, and containing communities minimally shifted in composition from local ones. Our inoculum contained abundant crust-forming cyanobacteria and no significant numbers of allochthonous phototrophs, and it was sufficient to treat ca. 6,000 m2 of degraded dryland soils at 1 to 5% of the typical crust biomass concentration, having started from a natural crust remnant as small as 6 to 30 cm2. IMPORTANCE Soil surface crusts can protect dryland soils from erosion, but they are often negatively impacted by human activities. Their degradation causes a loss of fertility, increased production of fugitive dust and intensity of dust storms with associated traffic problems, and provokes general public health hazards. Our results constitute an advance in the quest to actively restore biological soil covers by providing a means to obtain high-quality inoculum within a reasonable time (a few months), thereby allowing land managers to recover essential, but damaged, ecosystem services in a sustainable, self-perpetuating way as provided by biocrust communities.
