![]() ![]() One of the reasons for this is our incomplete understanding of the past natural vegetation distribution in the various topographic units of the CLP under different climate scenarios. Although the Chinese government has addressed the problem of soil erosion via an afforestation programme, there have been several negative outcomes. Soil erosion and related ecological restoration present a tremendous challenge to the socioeconomic development of the Chinese Loess Plateau (CLP). Sun, Aizhi Guo, Zhengtang Wu, Haibin Li, Qin Yu, Yanyan Luo, Yunli Jiang, Wenying Li, Xiaoqiang Reconstruction of the vegetation distribution of different topographic units of the Chinese Loess Plateau during the Holocene Finally, the relative contributions of environmental, current and historic anthropogenic factors on vegetation distribution were assessed using regression-based variation partitioning. between the number of BRT false presences per grid cell and human impact was evaluated using hurdle models. Subsequently, to test for anthropogenic vegetation transformation, the relationship. The contribution of each predictor variable to the best models and the accuracy of all models were assessed. types, represented by remote-sensing-based land-cover (LC) types, as a function of environmental factors. Methods  Boosted regression trees (BRTs) were used to model the distribution of African vegetation. Greve, Michelle Lykke, Anne Mette Overgaard, Anne BlachĪim  To assess the influence of natural environmental factors and historic and current anthropogenic processes as determinants of vegetation distributions at a continental scale. If farmers want to improve their economic condition, it needs innovation and creativity in the process of planting, harvesting, packaging and marketing vegetable products.Įnvironmental and anthropogenic determinants of vegetation distribution across Africa Intermediate distribution channels play a greater role in determining vegetable prices. The type of distribution channel prevailing in Boyolali area are traditional and modern distribution channels. Respondents from this study consisted of farmers, wholesalers, small trader and end consumers. The method used in this research is quantitative and qualitative. This study aims to identify the distribution channel and the formation of vegetable prices derived from Boyolali area. The limited amount of vegetable production and the inhibition of the vegetable distribution channel creates a scarcity of vegetables that result in price increases. Currently the number of vegetable production in Boyolali region can no longer meet the needs of local communities. Identification of Distribution Channels to Create Sustainable Vegetable Pricesĭirectory of Open Access Journals (Sweden)įull Text Available The price of vegetables has a role as a contributor to the rate of inflation. ![]() While promising, more work is needed to understand the impacts of such programs on in-store environments and consumer behaviors. Results suggest that healthy food distribution programs may reduce certain supply-side barriers to offering fresh produce in small retail venues. Produce prices offered through the program approximated those at wholesale markets, and were lower than prices at full-service grocers. ![]() Analysis of sales data showed that, on average, the total volume of produce distributed through the program increased by six pounds per week over the study period (95% confidence limit: 4.50, 7.50) trends varied by store and produce type. One-fourth of survey respondents reported no recent experience selling produce. ![]() Seventeen stores participated in the program over the study period. Assessment methods included: (1) a brief survey examining the characteristics, purchasing habits, and attitudes of stores entering the program (2) longitudinal tracking of sales data examining changes in the volume and variety of fruits and vegetables distributed through the program and (3) the collection of comparison price data from wholesale market databases and local grocery stores. This study examined the impacts of a healthy food distribution program in Los Angeles County over its first year of operation (August 2015-2016). While promising, little is known about how these programs affect the availability of fresh fruits and vegetables in underserved communities. Healthy food distribution programs that allow small retailers to purchase fresh fruits and vegetables at wholesale prices may increase the profitability of selling produce. Early Impacts of a Healthy Food Distribution Program on the Availability and Price of Fresh Fruits and Vegetables in Small Retail Venues in Los Angeles.ĭeFosset, Amelia R Gase, Lauren N Webber, Eliza Kuo, Tony ![]()
