Economic Damage

In developing countries in general and in Vietnam in particular, flood induced economic loss of agriculture is a serious concern since the livelihood of large populations depends on agricultural production. The objective of this study was to examine if climate change would exacerbate flood damage to agricultural production with a case study of rice production in Huong Son District of Ha Tinh Province, North-central Vietnam. The study applied a modeling approach for the prediction. Extreme precipitation and its return periods were calculated by the Generalized Extreme Value distribution method using historical daily observations and output of the MRI-CGCM3 climate model. The projected extreme precipitation data was then employed as an input of the Mike Flood model for flood modeling. Finally, an integrated approach employing flood depth and duration and crop calendar was used for the prediction of potential economic loss of rice production. Results of the study show that in comparison with the baseline period, an increase of 49.14% in the intensity of extreme precipitation was expected, while the frequency would increase 5 times by 2050s. As a result, the seriousness of floods would increase under climate change impacts as they would become more intensified, deeper and longer, and consequently the economic loss of rice production would increase significantly. While the level of peak flow was projected to rise nearly 1 m, leading the area of rice inundated to increase by 12.61%, the value of damage would rise by over 21% by 2050s compared to the baseline period. The findings of the present study are useful for long-term agricultural and infrastructural planning in order to tackle potential flooding threats to agricultural production under climate change impacts.

The provisions of food in order to fulfill the requirement for humankind could be followed through the implementation of the process of agricultural production. However, the food requirement could only be fulfilled self-sufficiently if food supplies were higher than the total consumption. The trend of the Indonesian rice production rises the problem that immediately must be overcome. This was caused by increasing consumption continuously resulting from the increase in population growth. Besides that, the other problems are rice field transformation, from rice field to industrial and residential area.

<p>Food security has long been a challenge for East Africa region and is becoming a pressing issue for the coming decades because food demand is expected to increase considerably following rapid population and income growth. Agricultural production in the region is thus required to intensify, in a sustainable way, to keep up with food demand. However, many challenges face the sustainable intensification of the agricultural production including low productivity, inadequate management, small scale operations, and large climate variability. Several pilot initiatives, that involves a bundle of land and water management practices, have been introduced in the region to tackle such challenges. However, their large-scale implementation remains limited. In the framework of a research project which is jointly implemented by the International Institute for Applied System Analysis (IIASA), the Lake Victoria Basin Commission (LVBC) and the International Crops Research Institute for Semi-Arid Tropics (ICRISAT), we analyse up scaling opportunities for water and land management practices for the sustainable and resilient intensification of rice and fodder production systems in the extended Lake Victoria Basin in East Africa. The expected outcome of this project is to provide an improved understanding of up scaling of such practices through model simulations and integrated analysis of political economy aspects, governance and social and gender dimensions.</p><p>This paper presents an integrated upscaling modeling framework that combines biophysical suitability analysis and economic optimization. Several production system options (i.e., management practices) for rice intensification are examined at high-spatial resolution (0.5°x0.5°) in the extended Lake Victoria basin. The suitability analysis identifies suitable area for the production system options based on a combination of various biophysical factors such as climate, hydrology, vegetation and soil properties using the Global Agroecological Zones (GAEZ) model and the Community Water Model (CWaTM). The economic optimization identifies the optimal combination of those production systems that maximizes their overall contribution to agricultural economic benefits having satisfied various technical and resource constraints including commodity balance, land availability and suitability, water availability, labor availability and capital constraints. A set of socioeconomic (e.g., impact of population and income growth on food demand and agricultural productivity) and climate change (e.g., impact on water resources availability) scenarios based on combinations of the Shared Socioeconomic Pathways (SSPs), Representative Concentration Pathways (RCPs), and co-developed bottom-up policy scenarios, through stakeholders’ engagement with the Basin Commission (LVBC), have been utilized to simulate the modeling framework. Results of this study show the existence of significant opportunities for the sustainable intensification of rice production in East Africa. Moreover, the study identifies the key biophysical and economic factors that could enable the upscaling of sustainable land and water management practices for rice production in the region. Overall, this study demonstrates the capacity of the proposed upscaling modeling framework as a system approach to address the linkages between the intensification of agricultural production and the sustainable use of natural resources.</p>

The article considers methodical aspects of rice production planning in agricultural enterprises. The existence of a multitude development options for the rice production is affirmed, and in this connection the necessity of its optimal industrial structure is justified. The relationship between the distribution and specialization of agricultural production, as two different sides of the same process, is shown, the intertwining of natural and economic conditions, the uneven use of labor resources and fixed productive assets, that determine the territorial division of labor in agriculture and whose existence necessitates a combination of industries that are rational selection of crops and their varieties.

Increased demand for water for municipal and industrial uses throughout Taiwan has intensified the pressure to re-allocate water from agricultural to non-agricultural uses. The full policy implications of such water transfers must not only account for the value of lost agricultural production and income, but also any loss in the social value of multifunctional benefits from agricultural production. Focusing on two northern irrigation associations in Taiwan, this paper empirically assesses the changes in rice production and multifunctional values under the scenario of transferring water from agricultural to non-agricultural uses. We also compare these combined multifunctional values of land in agricultural production with the per hectare compensations for water transfer in 2002 to evaluate the current water transfer mechanism. The empirical results have significant policy implications. Despite substantial reductions in production and farm income, the compensation levels in both irrigation regions exceed those required to compensate farmers for the losses in net farm revenue, and do so by substantial margins.

Until 1949, Communist rule was still restricted to states where wheat forms the basis of agricultural production. But when Mao Tse-tung extended his control to territories south of the Yangtse river, thereby enabling Ho Chi Minn to establish later a twin régime hi North Vietnam, the problem of collectivisation first appeared in tropical areas where rice is the main agricultural crop. From then on, an unforeseen problem of major importance has confronted the two Asian Communist leaders. Unlike their other colleagues in the Socialist camp, these two have had to adapt the rigorous norms of the collective system to the production of rice, an extremely delicate aquatic plant. Their relentless efforts to accomplish this are unprecedented and, now that the practical experiment has been in progress for several years, it is possible to make a preliminary appraisal of the results.

Nesting Place

The farmers in Pangkalan Gelebak Village have the problem of their low agricultural productivity.  The high price of chemical fertilizers causes the ability of the population to purchase fertilizers to be deficient.  As a result, agricultural production is still far from optimal.  In addition, rice straw left alone in rice fields can become a nesting place for pests such as rats, leafhoppers, and others.  Therefore, it is necessary to transfer information on appropriate science and technology, which is environmentally friendly, to overcome the problems of farmers in Pangkalan Gelebak.  One way to overcome this is to provide counseling about the importance of processing rice straw into biofertilizers to increase production, train, guide, and practice techniques for making biofertilizers made from rice straw to increase agricultural production, especially rice, and practicing application techniques for biofertilizer made from rice straw.  Rice straw is the raw material for rice plants for farmers in Pangkalan Gelebak Village.  The method used is to make demonstration plots of rice plants organically, counseling about the importance of processing rice straw into biofertilizers to increase production, carried out from February to June 2018.  The results of using 400 kg/ha + 50 % chemical fertilizers can increase rice production from 3,5 tons/ha to 5,6 tons/ha (60,00% increase) when compared to using chemical fertilizers.

Institutional Framework

The Question Of the relative efficiency of agricultural production within the institutional framework of slavery flared in the 1970s. Fogel and Engerman (1971, 1977) found antebellum Southern agriculture to have been considerably more productive than previously thought. Although this aspect of their finding became generally accepted, the controversy focused on just how efficient slave production actually was compared to Northern agriculture (David and Temin, 1974; David et al., 1976; Schaefer and Schmitz, 1979; Wright, 1979).
