This paper investigates the effects of agricultural aid on food security in African countries during the the 1990 to 2012 period. Defining food security as increases in agricultural productivity and controlling for a large number of covariates, we find that agricultural aid, at the aggregate level, aid to the agricultural sector has positive and statistically significant effect on food security...

Based on China’s carbon emissions of agriculture, the authors appraise the area differentiation of carbon emissions of agriculture; examine the influential factors of agricultural carbon emissions in China. The results show that the performance of China’s agricultural carbon emissions is on the rise. The agricultural carbon emissions in the west of China increase rapidly. The area differentiati...

In North Carolina, secondary agricultural education programs can now offer a state adopted integrated biotechnology course entitled Biotechnology and Agriscience Research. Empirical evidence was needed to identify and describe factors related to the intent of agricultural educators to adopt this curriculum in order to assist teachers during this transition. North Carolina agricultural educators...

Recently, land use and land cover change have received increased attention, and an approach is required that can assess agricultural land use intensity on a general basis. This study demonstrated the usefulness of a tool for characterizing and assessing agricultural land use intensity in Beijing mountainous region. An emergy analysis and principal component analysis (PCA) were adopted to obtain...

The exploratory correlational-regression study investigated the extent that the variability in the number of agricultural awareness activities conducted by elementary teachers in east-central Iowa could be explained by selected teacher characteristics—degree of education, grade level, agricultural classes, agricultural experience, and perceptions toward integrating agriculture. A sample of 689 ...

Increase in CO2 emissions induced by agricultural inputs in China since its socialist market economic reforms may hinder its sustainable economic development. More attention has been paid to changes in agricultural land use and overall land use benefit; however, relatively less attention has been paid to changes in CO2 emissions induced by agricultural inputs in China since the reforms. The car...

Xinjiang's agricultural carbon emissions showed three stages of change, i.e., continued to rise, declined and continued to rise, during 1991-2014. The agriculture belonged to the "low emissions and high efficiency" agriculture category, with a lower agricultural carbon emission intensity. By using the logarithmic mean divisia index decomposition method, agricultural carbon emissions were decomp...

On the example of a commercial microfinance institution (MFI) in Tanzania this paper investigates first whether agricultural firms have a different probability to get a loan and whether their loans are differently volume rationed than loans to non-agricultural firms. Second, we analyze whether agricultural firms repay their loans with different delinquencies than non-agricultural firms. Our res...

Agricultural productivity is determined and limited in general by a combination of the natural environment and technical measures. If non-capital intensive management is assumed, the natural potential and constraints are of specific importance for the agricultural land use and its productivity. In this context, the Potsdam Institute for Climate Impact Research (PIK) in cooperation with the Max ...

a r t i c l e i n f o A good harvest usually leads to a collapse of agricultural prices since the price elasticity of agricultural products is relatively low. To stabilize the market and protect farmers, many countries have introduced a target zone policy, together with product purchasing or price subsidy strategies. This article analyzes the effect of a target zone with different strategies op...
