Mental performance in 8-year-old children fed reduced protein content formula during the 1st year of life: safety analysis of a randomised clinical trial

In humans, maximum brain development occurs between the third trimester of gestation and 2 years of life. Nutrition during these critical windows of rapid brain development might be essential for later cognitive functioning and behaviour. In the last few years, trends on protein recommendations during infancy and childhood have tended to be lower than that in the past. It remains to be demonstrated that lower protein intakes among healthy infants, a part of being able to reduce obesity risk, is safe in terms of mental performance achievement. Secondary analyses of the EU CHOP, a clinical trial in which infants from five European countries were randomised to be fed a higher or a lower protein content formula during the 1st year of life. Children were assessed at the age of 8 years with a neuropsychological battery of tests that included assessments of memory (visual and verbal), attention (visual, selective, focused and sustained), visual-perceptual integration, processing speed, visual-motor coordination, verbal fluency and comprehension, impulsivity/inhibition, flexibility/shifting, working memory, reasoning, visual-spatial skills and decision making. Internalising, externalising and total behaviour problems were assessed using the Child Behaviour Checklist 4\u201318. Adjusted analyses considering factors that could influence neurodevelopment, such as parental education level, maternal smoking, child\u2019s gestational age at birth and head circumference, showed no differences between feeding groups in any of the assessed neuropsychological domains and behaviour. In summary, herewith we report on the safety of lower protein content in infant formulae (closer to the content of human milk) according to long-term mental performance

Tenure insecurity and investment in soil conservation: evidence from Malawi

Tenure insecurity can have important consequences for the conservation of natural resources. This paper focuses on two main sources of tenure insecurity, informal short-term tenancy contracts, and customary gender-biased inheritance practices. Using a large plot-level dataset from Malawi, the analysis employs a linear probability model with household fixed effects and finds that both sources of insecurity have a negative effect on soil conservation investments. These findings suggest that future land reforms should deal with the informality of the land rental market and address the gap between users and owners of land created by existing customary practices

Effects of dual land ownerships and different land lease terms on industrial land use efficiency in Wuxi City, East China

In the current Chinese land administration system, two types of land ownership including state and collective ownership coexist and the industrial land use rights can be transferred between different land lease terms. Previous studies found the significant relationship between land ownerships and lease terms with agriculture land use efficiency, but it is still unclear for the industrial land use efficiency. This study researched the effects of China's dual land ownerships and land lease terms on rural town industrial land use efficiency. Questionnaires of 294 industrial enterprises in Hudai, Qianqiao, and Xibei in Wuxi City, East China, were studied using two multiple linear regression models. The results showed that collective land with incomplete property rights caused land use inefficiency of lower industrial enterprises’ output per hectare of land. The industrial enterprises’ outputs per hectare from collective land were 2.16 million Yuan (0.31 million US dollar) and 2.06 million Yuan (0.30 million US dollar) less than those from state land in these two models, respectively. Different land lease terms negatively correlated with the use efficiency of rural industrial land. The outputs per hectare of industrial enterprises using the long term lease were 1.30 million Yuan (0.19 million US dollar) less than those using the short term lease in model 2. Our results highlight the importance of the integrated urban-rural land system and tailored lease terms of industrial land to increase the utilization efficiency of industrial land

Titling community land to prevent deforestation: An evaluation of a best-case program in Morona-Santiago, Ecuador

Assigning land title to collective landholders is one of the primary policies land management agencies use to avoid deforestation worldwide. Such programs are designed to improve the ability of landholders to legally exclude competing users and thereby strengthen incentives to manage forests for long-term benefits. Despite the prevalence of this hypothesis, findings about the impacts of land titling programs on deforestation are mixed. Evidence is often unreliable because programs are targeted according to factors that independently influence the conversion of forests. We evaluate a donor-funded land titling and land management program for indigenous communities implemented in Morona-Santiago, Ecuador. This program offers a close to best case scenario for a land titling program to reduce deforestation because of colonization pressure, availability of payments when titled communities maintain forests, and limited opportunities for commercial agriculture. We match plots in program areas with similar plots outside program areas on covariates that influence the conversion of forests. Based on matched comparisons, we do not find evidence that land titling or community management plans reduced forest loss in the five years following legal recognition. The results call into question land titling as a direct deforestation strategy and suggests land titling is better viewed a precursor to other programs. (C) 2015 The Authors.

Tenure security, human capital and soil conservation in an overlapping generation rural economy

We develop an overlapping generation model of rural agricultural households to examine whether tenure security and subsistence needs influence the choice between unexploited topsoil and investment in children's human capital as the mode of transfer of wealth. A unique dataset from Bangladesh finds that tenure security is associated with greater topsoil conservation and lower human capital investment. Therefore, there exists a tradeoff between these two modes of transfer. We suggest that increased public expenditure on schooling, which substitutes private expenditure, may lower the pressure on land and soil resources

Economics of Land Degradation Initiative: Methods and Approach for Global and National Assessments

Healthy land ecosystems are essential to sustainable development, including food security and improved livelihoods. Yet, their key services have usually been taken for granted and their true value underrated, leading to land degradation becoming a critical global problem. This pattern of undervaluation of lands is about to change in view of the rapidly rising land prices, which is the result of increasing shortage of land and high output prices. Despite the urgent need for preventing and reversing land degradation, the problem has yet to be appropriately addressed. Policy actions for sustainable land management are lacking, and a policy framework for action is missing. Such a framework for policy action needs to be supported by evidence-based and action-oriented research. The Economics of Land Degradation (ELD) initiative seeks to develop such a science basis for policy actions to address land degradation. The purpose of this methodological paper is to provide with sound and feasible standards for ELD assessment at global and national levels. Only if some basic standards are identified and adhered to, comparative assessments can be conducted between countries and useful aggregation of findings, based on these case studies, can be achieved. Therefore, using the Total Economic Value (TEV) framework, the paper identifies minimum core standards that need to be adhered to in all country case studies to generate comparable material for international assessment and ELD policy guidance. It also identifies additional and desirable areas of information and analyses that would add value to the country case study material. The proposed framework is also intended as a forward-looking agenda which can guide future research
