Data of this study were collected from primary and secondary sources. Primary sources of data were collected using two sets of structured questionnaires. A total number of three hundred （300） questionnaires were administered on categories of respondents in this study. Results of this study revealed that food crops are the major crops cultivated in the study area, and the effects of climate change on agricultural production results in soil loss, plant nutrient loss, textural change, increase in pest and diseases and poor yield germination etc.. This study therefore recommended that cover trees should be planted, which will provide shade and reduce heat, due to climate change and the preservation of underground water.展开更多

In this paper, the main policies that influence agricultural NPS pollution are chosen, and a method to evaluate the impacts of agricultural and rural economic policy system on agricultural NPS pollution is brought forward. According to this, the questions about how and to what degree the policy system influence on agricultural NPS pollution are discussed.展开更多

This study analysed the impact of CC on forestry and agriculture in a typical UK rural environment. The study interrogates this complex question using the Perception Based Analysis (PBA) methodological approach. Data analysis utilized chi square test and one-way analysis of variance (Anova) in comparing the impact of climate change and human factors on forest and agricultural ecosystems, (significance level α = 5%), calculated ρ = 0.36 > 0.05. This non-significant ρ value suggests that the null hypothesis Ho “climate change is responsible for the changes in forest and agricultural ecosystem in the case study area” could be true.展开更多

From sponge cities to sponge villages, it is an effective way to use the low-impact development (LID) technology to solve rural water ecological environment problems. Through the investigation and analysis of the hydrology, soil, runoff, vegetation and other factors in the Wei River wetland of Fengxi New City of Xixian New Area, this study attempts to construct a LID route suitable for managing the rural water ecological environment in the northwest, so as to provide a reference for the construction of green infrastructure and sponge cities of rural areas in the northwest.展开更多
