农业生产“三品一标”促进农民增收的作用机理及实现策略

农民农业生产质量效益较低,是导致其农业经营增收乏力的重要原因。农业生产“三品一标”对提高农民的农业经营质量效益有积极作用,有助于破解生产成本高企、同质化低价竞争、分享全产业链增值收益不足、生产经营风险高的困局。实施农业生产“三品一标”促进农民增收,会遇到小农户较难直接对接“三品一标”行动且与“三品一标”的要求不够适应、规模农户投资“三品一标”的成本压力和收益风险较大、农产品“优质不优价”等难点问题。为此,要构建小农户与农业生产“三品一标”的有效衔接机制,适应农业生产“三品一标”的要求提升小农户发展能力,降低规模农户投资“三品一标”的成本压力和收益风险,建立健全农产品优质优价的良性机制。

Standards of Ecological Compensation for Traditional Ecoagriculture:Taking Rice-Fish System in Hani Terrace as an Example

Traditional eco-agriculture provides many ecosystem services which are important for the local environment, especially in mountain areas. In order to encourage the farmers to engage in coo-agriculture, it is necessary to establish an eco-compensation mechanism for them. As the compensation standard is one of key issues in establishing eeo-compensation mechanism, this paper calculated the standard based on the farmers＇ willingness to accept （WTA） and the input-output analysis of eco-compensation. We took the traditional rice-fish eco-agriculture as the research object, conducting field surveys in Hani Terrace of Honghe County. Through the questionnaires in 2o11, we obtained the farmers＇ willingness to accept government compensation and market compensation. Then, the research evaluated the output of eco-compensation, the economic value of rice-fish paddy ecosystem services. Finally, under different market compensation standards, we compared the input and output of government compensation. The results show that, in 2011 the government should to pay farmers 7462 yuan.ha^-1·a^-1 to meet their willingness, but the output （ecological benefit） was only 7393 yuan.ha^-1·a^-1. However, whenthe rice price increases 1 yuan·kg-1 because of the limited use of chemicals in the next year, the government just has to pay farmers 4062 yuan.ha^-1·a^-1 and the surplus will be 3331 yuan.ha^-1·a^-1.

Sustainability of Local Food Supply Chain in the New Theory Agriculture

World food production and its economic have rapidly grown over a decade; and number of supply chain management research has also increased in this field. However, this development relates to natural resources depletion and deterioration of quality of life in rural population, especially in smallholder farmers. Thailand has practiced the New Theory Agriculture （NTA）, one application aligned with sufficient economy. This theory not only remedies damaged natural resources but also helps smallholder farmers to improve quality of life; and it is analogous to local food supply chain theory, that is well-known in western countries. However, NTA has not been measured its sustainability. Following sustainable food criteria and sustainable agriculture criteria, this paper uses an Indicator of Sustainable Agricultural Practice （ISAP） to measure sustainability at farm level of small rural community＇s network called Inpaeng, a case study that has practiced NTA. The result of assessment in this case implies that NTA yields sustainability to local food supply chain more than monocrop system.

Trends in major and minor meteorological variables and their influence on reference evapotranspiration for mid Himalayan region at east Sikkim, India

Abstract： Estimation of evapotranspiration （ET） for mountain ecosystem is of absolute importance since it serves as an important component in balancing the hydrologic cycle. The present study evaluates the performance of original and location specific calibrated Hargreaves equation （HARG） with the estimates of Food and Agricultural Organization （FAO） Penman Monteith （PM） method for higher altitudes in East Sikkim, India. The results show that the uncalibrated HARG model underestimates ET0 by 0.35 mm day^-1 whereas the results are significantly improved by regional calibration of the model. In addition, this paper also presents the variability in the trajectory associated with the climatic variables with the changing climate in the study site. Non- parametric Mann-Kendall （MK） test was used to investigate and understand the mean monthly trend of eight climatic parameters including reference evapotranspiration （ET0） for the period of 1985 - 2009. Trend of ET0 was estimated for the calculations done by FAO PM equation. The outcomes of the trend analysis show significant increasing （p ≤ 0.05） trend represented by higher Z-values, through MK test, for net radiation （Rn）, maximum temperature （Tmax） and minimum temperature （Train）, especially in the first months of the year. Whereas, significant （0.01 ≥ p ≤0.05） decreasing trend in vapor pressure deficit （VPD） and precipitation （P） is observed throughout the year. Declining trend in sunshine duration, VPD and ET0 is found in spring （March - May） and monsoon （June - November） season. The result displays significant （0.01≤ p ≤0.05） decreasing ET0 trend between （June - December） except in July, exhibiting the positive relation with VPD followed by sunshine duration at the station. Overall, the study emphasizes the importance of trend analysis of ET0 and other climatic variables for efficient planning and managing the agricultural practices, in identifying the changes in the meteorological parameters and to accurately assess the hydrologic water balance of the hilly regions.

Climatology of Guinea： Study of Climate Variability in N＇zerekore

N＇zerekore is a geographical region of Guinea, which houses a weather observatory located at longitude 8.8°, latitude 7.7° and altitude 475 m. This region is of major socio-economic interest for the Country. The climatological study of this region shows the variability of each parameter. The objective of this study was to analyze meteorological parameters trends and to assess the space-time evolution of some agro-climatic risks related to the main trends observed in the meteorological parameters regime of this region. In this study, programming tools were used for processing and analyzing meteorological parameters data, including temperatures, rains, wind, evaporation and storms measured in this observatory from 1931 to 2014. The interannual, annual and daily variations of these parameters were obtained, as well as temperature, precipitation anomalies and agroclimatic indexes trends. The analyzing of these variations explained that September is the rainiest months, and the year 1932, 1957 and 1970 are normal, rainy and dry year, respectively. The evaporation increased since 1971 from January to March and November to December. A positive temperature anomaly was observed since 1973 with the maximum 26-33 ℃ and the minimum 16-21 ℃. A dominant westerly wind with a speed of 2.6 m/s was determined. Agro-climatic parameters in N＇zerekore have high variability. From 1931 to 2014, three major periods can be distinguished： a wet period from 1931 to 1977, a dry period from 1978 to 1994 and rainfall variability from 1995 to 2014. The trend of these parameters explains the impact of climate change in this part of the world. This is exacerbated by human activity （deforestation）, thus mitigation measures are necessary. It would be useful to extend this study throughout the country.

Institutional Constraints to the Competitiveness of the South African Citrus Exports

This paper examined the dual institutional constraints arising from the market liberalisation of the South African citrus industry and the stringent food safety health and private standards associated with the globalisation of the agri-business industry. The aim of this paper was to explore the institutional challenges influencing the competitiveness of the South African citrus industry in the export markets. It also explored the implications of the institutional environment on market access. The logistic regression model was used to analyse the statistical data while simple ranking was used to indicate the new and emerging forces affecting the profitability of the industry in recent years. The results show that access to market information, economies of scale, compliance with strict food safety and quality standards, lack of proper infrastructure including transport and challenges of managing a business within the international business environment exerted significant effects on the competitiveness of the industry as well as the ability of domestic producers to enter the export markets. There is need for government intervention especially aligned to investing in infrastructure. Coupled with the support of private institutions, the government needs to support the exporters and producers in complying with private standards.

The circulation physiology of agroecosystems

This paper represents an effort to enlarge the understanding of the biophysical foundation of agroecosystemsby using an analogy with the circulation of the blood in the human body. The circulation function in the human body canbe represented as arterial pressure. The factors affecting arterial pressure in the human body have direct counterpartsin the cultivation-husbandry system. The relationship between circulation pressure and the factors affecting that pressurein the cultivation-husbandry system are similar to the relationship between the arterial pressure and factors affectingarterial pressure in the human body. Furthermore, circulation resistance in the cultivation-husbandry system can beshown to be analogous to the calculation of peripheral resistance in the human body by Poiseuille’s formula.

Factorial analysis of the effect of sugarbeet vinasses on agroecological indices in horticultural field

The impact on soil of applying sugarbeet vinasses （V） was analyzed through a field experiment in horticulture greenhouse, arranged in a 23 factorial design. Two levels of three independent variables--application of V, use of polyethylene cover （PC） on the soil. and soil depth （D）---on various dependent variables were studied. Vinasses favoured crop yield and reduced the number of Meloidogyne incognita juveniles in soil. The concentrations ofN. P and K increased with the interaction VxD, with PC also increasing N concentration. The amounts of humic acids and humin decreased with D; fulvic acid concentration increased with V, but decreased with the interaction VxPC. Soil physical factors were improved mainly with D and V. Aromaticity of humic acid-like fractions increased ~＇itb V. In general, V showed significant effects mainly on the topsoil, suggesting low leaching risks. The results indicate that the levels of the independent factors improving a group of variables were not the same that those contributing to another group. Therefore, their best combination should be determined for each scenario to achieve optimum agroecological performance.

Survey and Conservation of Indigenous Fruits of Western Ghats

Western Ghats region of India is one of the biodiversity hotspots of the world. The topography, wide rainfall variation and varied temperature conditions enable inhabitancy of several plant species. This plant wealth is being used in various forms by tribes and natives of the area for centuries. These gain further importance due to the fact that ripe fruits serve as a source of food and medicine to tribes throughout the year. These wild fruits are source of minerals and vitamins in the diet of the rural people. The potential productivity and floristic diversity of the area have attracted the experts. There are more than 50 wild edible fruit species are available in Western Ghats region. These belong to 25 families and 38 genera. Out of the 25 families, the important ones as a source of fruits are Apocynaceae, Anacardiaceae, Euphorbiaceae, Moraceae, Sapotaceae and Sapindaceae. The fruiting period of different species ranges between two and six months. The highest number of species mature from April to May. The availability of these fruits reduces after October. Some of these fruits, such as Mangifera indica, Artocarpus heterophyllus, Carissa carandas, Emblica officinalis and Syzygium cuminii, have been given emphasis in order to identify high yield and high fruit quality clones and standardization of production technologies. The collection, conservation and utilization on some of the fruits, such as Garcinia indica and Garcinia gummigutta have started at various research organizations. Some other fruits, namely Chrysophyllum roxburghii （Family Sapotaceae）, Canthium parviflora Lamk syn. Plectronia parviflora （Lam.） Bedd. （Family Rubiaceae）, Elaeagnus conferta Roxbsyn, Elaeagnus latifolia L. （Family Elaeagnaceae）, Securina leucopyrus syn. Flueggea leucopyrus （Family Euphorbiaceae）, Elaeocarpus tuberculatus Roxb. （Family Elaeocarpaceae）, Nephelium stipulacum Bedd. syn. Doratoxylon stipulatum （Family Sapindaceae） have potential for commercial cultivation. Thus, attempts were made with the objective of recording availability of these species, proximate analysis and their on farm and off farm conservation at Central Horticultural Experiment Station （CHES）. Few plants were also provided to local growers on farm conservation. The continuous depletion of forest and the increasing human disturbance resulted in losses of these species. There is need to conserve these fruits for future.

Ecoagriculture evaluation of household level in red soil area of China

A hundred and twenty-one households in Yujiang county, Jiangxi province were investigated by adopting questionnaire method, and the evaluation system of index was established according to the integrative, hierarchical, scientific, practical, comparative and dynamic principles. The investigation data were firstly standardized and then processed with SPSS software. The index weight was confirmed by principal component analysis. Finally, the evaluation scale of ecoagriculture was calculated. The results showed that the evaluation value ranged from 0.141 to 0.689 for 121 households. Agricultural status of 113 households got the primary phase of ecoagriculture which accounting for 93.38%; 7 households into the second phase, representing 5.79% and only 1 household into the third phase according to the evaluation value. However, the ecoagriculture was divided into 5 stages, according to the evaluation value. Therefore, the ecoagriculture has huge potential to develop in red soil area, China.

Private Provision of Environmental Public Goods:A Pilot Program for Agricultural Heritage Conservation

While the true value of environmental goods may be captured in a one-off payment, it may be easier to add a smaler amount to a private good by means of donation and colect the total environmental value over time. For that, however we need to ensure the smaller amount of a heritage conservation donation added to a private good is adequate so that we can ifnd retailers to participate in such fund-raising activities. We test the contingent valuation method’s criterion validity by comparing their stated purchasing behavior with their actual behavior. The price increase from the addition of the donation did not affect total sales of the commodity. Adding a donation to specialized private goods may be an effective way to colect landscape and agricultural heritage conservation do-nations. Furthermore, our ifndings suggest that funds can be colected without affecting commodity sales. This ap-proach is effective in other environmental protection activities.
