17pgs, There is a lack of data on resources used and food produced at urban farms. This hampers attempts to quantify the environmental impacts of urban agriculture or craft policies for sustainable food production in cities. To address this gap, we used a citizen science approach to collect data from 72 urban agriculture sites, representing three types of spaces (urban farms, collective gardens, individual gardens), in five countries (France, Germany, Poland, United Kingdom, and United States). We answered three key questions about urban agriculture with this unprecedented dataset: (1) What are its land, water, nutrient, and energy demands? (2) How productive is it relative to conventional agriculture and across types of farms? and (3) What are its contributions to local biodiversity? We found that participant farms used dozens of inputs, most of which were organic (e.g., manure for fertilizers). Farms required on average 71.6 L of irrigation water, 5.5 L of compost, and 0.53 m2 of land per kilogram of harvested food. Irrigation was lower in individual gardens and higher in sites using drip irrigation. While extremely variable, yields at well-managed urban farms can exceed those of conventional counterparts. Although farm type did not predict yield, our cluster analysis demonstrated that individually managed leisure gardens had lower yields than other farms and gardens. Farms in our sample contributed significantly to local biodiversity, with an average of 20 different crops per farm not including ornamental plants. Aside from clarifying important trends in resource use at urban farms using a robust and open dataset, this study also raises numerous questions about how crop selection and growing practices influence the environmental impacts of growing food in cities. We conclude with a research agenda to tackle these and other pressing questions on resource use at urban farms.
15pgs, ative NTFPs species are found. We surveyed Appalachian family forest owners in 14 Southwest Virginia counties about their interest in forest farming and likelihood of leasing land for this purpose. We also asked about the owner's residency and historical connection to the region as well as contemporary land uses, and identified the following types of uses: Absentee and vacationers, newcomers, longtime farming residents, and longtime nonfarming residents. We mailed 1,040 surveys and 293 were returned (28.9%). Forty-five percent were interested or extremely interested in forest farming and 36% were likely or extremely likely to lease land. Rates of interest in forest farming and leasing were similar across owner types, suggesting broad appeal among family forest owners.
9 pages, via online journal, The conversion of population and land from rural to urban areas has been widely explored; however, the spatial change in rural settlements and its relations to population changes involved in urbanization have been ignored. This paper aims to reveal the underlying human-land relationship from the perspective of rural settlement urbanization (RSU). Based on identifying the spatiotemporal characteristics of RSU in Wuhan city circle from 2009 to 2016, we analyzed the human-land relations using a combination of a dynamic coupling model and a decoupling model. The results showed that a total area of 27.77 km2 (accounting for 0.81% of the level in 2009) of rural settlements was converted to urban construction land from 2009 to 2016. Although the rural population decreased by 32.21%, the overall size of rural settlements increased by 104.62 km2, and 37 counties had a low-level coordination between population urbanization and RSU. Only 2 counties emerged with high-level coordination in this process. Additionally, the changes in rural settlements and rural population showed a strong negative decoupling; that is, the population decreased while the area of rural settlements increased. Combining the decoupling results with the coupling analysis, eight human-land relationship patterns in rural settlement urbanization were identified, and “strong negative decoupling–low-level coupling” was the main pattern observed in counties, which summarized the human-land relations in most RSU and should be given priorities in improving rural human-land relationships. The question of how to promote harmonious human-land relationships lies at the core of promoting balanced urban-rural development. This research could provide a decision-making basis for formulating a sustainable development strategy for urban-rural integration.
13 pages, Grassland farms form the basis of grassland resource management in China. Farm sizes in China are generally small, which obviously increases the risk of grassland ecosystems. It is necessary to analyze the impact of farm size on grasslands from the perspective of livestock production in order to improve grassland management. This study combines field investigations and statistical analysis from 2004 to 2020, using a total of 126 farms from the Xilinguole League of Inner Mongolia in China as samples. These sample farms are divided into large farms and small farms. Different production scale and management behaviors are explored, along with their different impacts on grassland resources use. The results show that the expansion of farm size is constrained by the government management policies. Different behaviors are adopted by large and small farms in terms of finance, grassland circulation, and overgrazing management. The differentiation mechanisms of different farm size and the utilization of grassland resources are clarified in this study. This work suggests that managers promote sustainable use based on farm size and build appropriate policies to avoid future risks. The results of this study can provide a framework for solving similar problems.

24 pgs, Increasing interest in farmers’ local soil knowledge (LSK) and soil management practice as a way to promote sustainable agriculture and soil conservation needs a reliable means to connect to it. This study sought to examine if Visual Soil Assessment (VSA) and farmer workshops were suitable means to engage, communicate and preserve farmers’ LSK in two mountainous communes of Central Vietnam. Twenty-four farmers with reasonable or comprehensive LSK from previously studied communes were selected for the efficacy of VSA and farmer workshops for integrating LSK into a well-accepted soil assessment tool (VSA). In field sites chosen by the farmers, VSA was independently executed by both farmers and scientists at the same time. Close congruence of VSA scores between the two groups highlighted that farmers could competently undertake VSA. Farmers’ VSA score was compared with their perception of field’s soil quality. For the majority of farmers’ perception of soil quality was consistent to their VSA score (62.5%), while the remainder perceived their soil quality was lower than their VSA score. For most farmers their assessment of soil quality using VSA valued their LSK, and the two measures were well aligned. Soil colour and presence or vulnerability to erosion were common soil characteristics mentioned by farmers and affected the final VSA score. Farmers’ participation in VSA and workshops strengthen farmers’ confidence in their LSK and provided guidance on the impact of their soil management on soil improvement and conservation.
9 pages, via online journal, Economists have touted partnerships between smallholders and agribusiness firms that cultivate high-valued export crops as a means of raising smallholder incomes and achieving rural development. However, some case studies show that such partnerships can deny smallholders the ability to benefit from their lands. This essay examines how this dynamic occurs by comparing the experiences of agrarian reform beneficiaries (ARBs) in the Davao Region of the Philippines. The paper finds that contracts which deny ARBs the benefit of their holdings are those that deprive them of key abilities such as determining who can use land and withdraw it from a partnership. Such contracts arise when ARB groups lack attributes that enhance their capacity for collective action, information gathering, and legal advocacy.

6 pages, via Online journal, Most agricultural soils are depleted of their soil organic matter (SOM) reserves. A severe loss of SOM content may degrade soil functionality, its capacity for provisioning of essential ecosystem services, and soil health. Therefore, restoration of SOM content in soils of agroecosystems may reverse the degradation trends, enhance ecosystem services (Banwart et al. 2015), and advance Sustainable Development Goals of the United Nations. (Lal et al. 2018a). Increase in SOM content may also partially replace the use of chemical fertilizers and supplemental irrigation, while restoring the environment.
