Tree Rings Reveal Mixtures Of Aspen And Spruce Exhibit Greater Drought Resilience In A Planted Field Experiment, Jéssica Chaves Cardoso, Linhao Wu, Marcel Schneider, Charles A. Nock

Aspen Bibliography

Boreal forests provide a wealth of ecosystem services, many of which are linked to forest productivity. Climate change is expected to increase the frequency, duration, and severity of drought, and undermine the productivity of western boreal forests. Favouring species mixtures has emerged as a potential strategy to increase forest resilience to drought. To test the hypothesis that mixtures of trembling aspen and white spruce were more productive than pure stands because they were more resistant and resilient to drought, we analyzed community and species responses to drought utilizing measurements of annual growth obtained from stem disc samples from a planted …

Nexus Between Rural Agricultural Land Ownership And Agricultural Credits Access: A Case Of Tanzania, Gelas Rubakula

Journal of Humanities and Social Sciences

Agricultural investment in low- and middle-income countries faces credit access challenges. Several financial institutions, particularly banks, normally impose some conditions where the possession of a land title deed is required to access agricultural credits. This paper examines whether, and to what extent, rural agricultural land ownership influences agricultural credit access for rural farmers in Tanzania. The study focuses only on rural farmers and tries to find out whether these smallholder farmers can use their land, which is largely unformalized, as a collateral for credit access. The study survey was cross-sectional, using quantitative data collected in December 2017 to March 2018 …

Leveraging Social Ties To Financial Gains: Exploring The Impact Of Social Capital In Rural Development, Mallory L. Rahe, Andrew J. Van Leuven, Trey Malone

Department of Agricultural Economics Faculty Publications

Social capital, defined as networks of individuals linked through bonding or bridging relationships, plays a crucial but poorly conceptualized role in place-based development. The word “capital” implies an underlying value of the social connections throughout a community, and this study explores how these social relationships are used to initiate, plan, access financial capital, and implement economic development projects in rural areas. We avoid county-level aggregation bias and use a divergent pathway case study of projects across eight communities to examine how social ties are used during rural development in places with both high and low financial capital. Both types of …

Place Branding: More Than Just A Logo, Marilyn R. Schlake

Cornhusker Economics

Place branding can distinguish one community from another. In a landscape of locations that provide the same amenities, environments, and opportunities, branding can help a community “stand out.” However, what is usually missing is a place brand developed in association with the community’s history, values, social connections, and organization associations that have evolved.

Turkish Journal of Agriculture and Forestry

Chromium (Cr) is an extremely toxic metal for all living organisms and its concentration in the environment is constantly increasing due to human activities. Plants quickly absorb the Cr subsequently, it enters the human food chain and poses serious health issues. Chromium toxicity causes a serious reduction in plant growth by inducing oxidative damage and disturbing protein synthesis, enzyme activity, and nutrient uptake. Plants use diverse mechanisms to mitigate the Cr toxicity however, they are inadequate against higher concentrations of Cr. Thus is essential to diminish Cr toxicity and increase the ability of plants to tolerate Cr stress. Nano-particles (NPs) …
