Understanding the determinants of agricultural productivity requires accurate measurement of crop output and yield. In smallholder production systems across low- and middle-income countries, crop yields have traditionally been assessed based on farmer-reported production and land areas in household/farm surveys, occasionally by objective crop cuts for a sub-section of a farmer’s plot, and rarely using full-plot harvests. In parallel, satellite data continue to improve in terms of spatial, temporal, and spectral resolution needed to discern performance on smallholder plots.
Previous literature suggests subpar teaching is a primary reason why rural Chinese students lag behind academically. We initiate an investigation into the potential of educational technology (EdTech) to increase teaching quality in rural China. First, we discuss why conventional approaches of improving teaching in remote schools are infeasible in China’s context, referring to past research. We then explore the capacity of technology-assisted instruction to improve academic performance by examining previous empirical analyses. Third, we show that China is not limited by the resource constraints of other developing countries due to substantial policy support and a thriving EdTech industry. Finally, we identify potential implementation-related challenges based on the results of a preliminary qualitative survey of pilots of EdTech interventions. With this paper, we lay the foundation for a long-term research investigation into whether EdTech can narrow China’s education gap.
Empirical evidence from developed countries supports the idea that parent-teacher interaction is high and improves student outcomes. The evidence from developing countries is, however, decidedly mixed. Using longitudinal data from nearly 6000 students and their 600 teachers in rural China, we show the prevalence of parent-teacher interaction is generally much lower than that of developed countries. We also show parent-teacher interaction, when it exists, can have positive effects on raising academic achievement and reducing learning anxiety. We demonstrate that the prevalence and effectiveness of parent-teacher interaction in a developing country context varies considerably due to both demand-side and supply-side factors.
Studies suggest that students’ prior performance can shape subsequent teacher evaluations, but the magnitude of reputational effects and their implications for educational inequality remain unclear. Existing scholarship presents two major perspectives that exist in tension: do teachers primarily use reputational information as a temporary signal that is subsequently updated in response to actual student performance? Or do teachers primarily use reputational information as a filter that biases perception of subsequent evidence, thus crystallizing student reputations and keeping previously poor-performing students stuck in place? In a field experiment, we recruited a random sample of 832 junior high school teachers from the second-most populous province of China to grade a sequence of four essays written by the same student, and we randomly assign both the academic reputation of the student and the quality of the essays produced. We find that (1) reputational information influences how teachers grade, (2) teachers rely on negative information more heavily than positive information, and (3) negative reputations are crystallized by a single behavioral confirmation. These results suggest that students can escape their prior reputations, but to do so, they must contradict them immediately, with a single confirmation sufficient to crystallize a negative reputation.
There is a significant gap in academic achievement between rural and urban students in China. Policymakers have sought to close this gap by improving the quality of teaching in rural areas through teacher professional development (PD) programs. However, there is limited evidence on the effectiveness of such programs. In this paper, we evaluate the impact of a PD program-National Teacher Training Program (NTTP) and find that the NTTP has no effect on math achievement. We also find that while the program has a positive effect on math teaching knowledge of teachers, it has no significant effect on teaching practices in the classroom. Taken together, these results indicate that teachers may have improved their knowledge for teaching from NTTP, but did not apply what they learned to improve teaching practices or student learning.
Wheat is the most important staple crop grown in Australia, and Australia is one of the top wheat exporting countries globally. Timely and reliable wheat yield prediction in Australia is important for regional and global food security. Prior studies use either climate data, or satellite data, or a combination of these two to build empirical models to predict crop yield. However, though the performance of yield prediction using empirical methods is improved by combining the use of climate and satellite data, the contributions from different data sources are still not clear.
Although students in rural and migrant schools in China generally have not performed well, a share of each cohort has been able to thrive in school and to test into academic high school and college. To understand the origins of persistence, specifically, why some students learn more than do others, researchers have identified certain sources of the problem. Few studies, however, have paid attention to the role that low levels of cognitive development of students play in their academic performance.
Understanding the causes of economic inequality is critical for achieving equitable economic development. To investigate whether global warming has affected the recent evolution of inequality, we combine counterfactual historical temperature trajectories from a suite of global climate models with extensively replicated empirical evidence of the relationship between historical temperature fluctuations and economic growth. Together, these allow us to generate probabilistic country-level estimates of the influence of anthropogenic climate forcing on historical economic output.
This paper describes the current level of human capital in China and seeks to identify a number of education-related challenges that may slow down the nation’s economy from transitioning to high-income status. Relying on recent census-based data from OECD for the rest of the world and using data from the 2015 Micro-Census for China, the authors show that the low levels of education of China’s labour force is really a problem that has its roots in the past (in the 1970s, 1980s, and 1990s). In recent years (since 2000), China has been investing heavily in education as shown by the increasing the share of youth, including rural youth, attending high school. Despite this recent effort to raise the nation’s human capital, the education system still faces several challenges in trying to provide high-quality education for all youth. First, the government must figure out a way to overcome the relatively low rates of participation in high school by rural students. Second, there is concern that many vocational schools, especially those in rural areas, cannot deliver quality education. Finally, the paper will show that many rural students may be unprepared due to poor early childhood development outcomes.
We assess and compare computer science skills among final-year computer science undergraduates (seniors) in four major economic and political powers that produce approximately half of the science, technology, engineering, and mathematics graduates in the world. We find that seniors in the United States substantially outperform seniors in China, India, and Russia by 0.76–0.88 SDs and score comparably with seniors in elite institutions in these countries. Seniors in elite institutions in the United States further outperform seniors in elite institutions in China, India, and Russia by ∼0.85 SDs. The skills advantage of the United States is not because it has a large proportion of high-scoring international students. Finally, males score consistently but only moderately higher (0.16–0.41 SDs) than females within all four countries.
The Ethiopian government is planning on constructing the country’s first light rail in its capital city Addis Ababa. The project is expected to bring both short-term and long-term benefits: it can help with alleviating the city’s traffic congestion problem, and more importantly, lay the technological foundation for Ethiopia’s grand strategy for a national railway system. Once completed, this modern public transport system will boost the political legitimacy of the incumbent regime.
Millions of people worldwide are absent from their country’s census. Accurate, current, and granular population metrics are critical to improving government allocation of resources, to measuring disease control, to responding to natural disasters, and to studying any aspect of human life in these communities. Satellite imagery can provide sufficient information to build a population map without the cost and time of a government census.
Malaysia is a Southeast Asian nation strategically located along major regional trade routes. Its national government must balance intense geopolitical pressures from neighboring countries with the need for domestic economic growth. In an effort to divert trade routes away from Singapore and to increase connectivity between its coasts, Prime Minister Najib Razak has signed a Memorandum of Understanding with China to build a Chinese-backed East Coast Rail Link (ECRL) across peninsular Malaysia. As an outspoken Member of Parliament in the opposition Democratic Action Party (DAP), Dr.
Unlike performance incentives for private sector managers, little is known about performance incentives for managers in public sector bureaucracies. Through a randomized trial in rural China, we study performance incentives rewarding school administrators for reducing student anemia -- as well as complementarity between incentives and orthogonally assigned discretionary resources. Large (but not small) incentives and unrestricted grants both reduced anemia, but incentives were more cost-effective. Although unrestricted grants and small incentives do not interact, grants fully crowd-out the effect of larger incentives. Our findings suggest that performance incentives can be effective in bureaucratic environments, but they are not complementary to discretionary resources.
Using the Bayley Scales of Infant and Toddler Development-III (BSID-III), we examine the rates of developmental delays among children aged 0–3 years in four major subpopulations of rural China, which, altogether, account for 69% of China's rural children and 49% of children nationwide. The results indicate that 85% of the 3,353 rural children in our sample suffer from at least one kind of developmental delay. Specifically, 49% of the children have cognitive delays, 52% have language delays, 53% have social emotional delays, and 30% have motor delays. The results suggest that these high rates are due to two main factors in the parenting environment. The first is micronutrient deficiencies, which are reflected in a high prevalence of anemia (42%). The second is an absence of interactive parenting inputs, such as storytelling, reading, singing, and playing. Although we find these inputs to be significantly and positively associated with better developmental outcomes, only a small share of caregivers engage in them. With this large and broad sample, we show that, if China hopes to build up enough human capital to transition to a high-income economy, early childhood development in rural areas urgently requires more attention.
Poor rural areas in China exhibit the country’s highest rates of child mortality, often stemming from preventable health conditions such as diarrhea and respiratory infection. In this study, we investigate the association between breastfeeding and disease among children aged 6–24 months in poor rural counties in China. To do this, we conducted a longitudinal, quantitative analysis of socioeconomic demographics, health outcomes, and breastfeeding practices for 1802 child–caregiver dyads across 11 nationally designated poverty counties in southern Shaanxi Province in 2013–2014. We found low rates of continued breastfeeding that decreased as children developed: from 58.2% at 6–12 months, to 21.6% at 12–18 months, and finally to 5.2% at 18–24 months. These suboptimal rates are lower than all but one other country in the Asia-Pacific region. We further found that only 18.3% of children 6–12 months old met the World Health Organization (WHO)-recommended threshold for minimum dietary diversity, defined as consuming four or more of seven specific food groups. Breastfeeding was strongly associated with lower rates of both diarrhea and cough in bivariate and multivariate analyses. As the first analysis to use longitudinal data to examine the relationship between continued breastfeeding and child illness in China, our study confirms the need for programmatic interventions that promote continued breastfeeding in order to improve toddler health in the region.
It is commonly believed that reading challenges should be addressed early to reduce the likelihood that developmental delays will impact students over the long term. However, students in developing countries often have limited access to reading resources. In this study, the authors used a randomized controlled trial of 11,083 fourth‐ and fifth‐grade students in 120 primary schools in rural China to examine the causal effect of an in‐class library program on student reading outcomes and academic achievement in schools with poor reading resources over an eight‐month period. An in‐class library was installed in each of the selected classes in the 40 treatment schools. The authors found that the program significantly improved student affinity toward reading and student reading habits, and in these regards, it narrowed the gap between male and female students, between low‐ and high‐performing students, and between left‐behind children and children living with parents. However, the authors found no overall effect of the program on reading and academic achievement and a negative effect on student confidence in reading. There was also no effect on student, teacher, and primary caregiver perceptions toward the effect of independent reading on academic achievement, nor any effect on whether teachers and primary caregivers provided reading instructions to students. The authors propose three possible explanations for these findings: a lack of reading instruction from teachers and caregivers, a lack of reading materials specifically tailored to local needs and interests, and the relatively short duration of the intervention.
In 2013, President Barack Obama announced Power Africa, the U.S.’s initiative to bring energy infrastructure to Sub-Saharan Africa. In the years following, the initiative enjoyed bipartisan support and congress passed enabling legislation in 2016. Despite early momentum for Power Africa, the initiative has yet to achieve its potential. This case follows the challenges and limitations of Power Africa in the face of growing and evolving Chinese pressures on the African continent. At a time when China is investing more than ever in Africa’s infrastructure, the U.S.
The emergence of a global digital ecosystem has been a boon for global communication and the democratization of the means of distributing information. The internet, and the social media platforms and web applications running on it, have been used to mobilize pro-democracy protests and give members of marginalized communities a chance to share their voices with the world.
On August 9, 2018, the Shorenstein Asia Pacific Research Center (APARC) hosted a conference, “Break Through: Women in Silicon Valley, Womenomics in Japan" with support from the Acceleration Program in Tokyo for Women (APT).
This publication summarizes the agricultural policy analyses conducted in nine Caribbean countries (Suriname, Guyana, Haiti, Dominican Republic, Jamaica, Belize, Barbados, The Bahamas, and Trinidad and Tobago) in the framework of the IDB’s Agrimonitor initiative. The document discusses how agricultural policies affect producers and consumers as well as how the limited funding for agricultural services, such as research and infrastructure, could limit the ability of Caribbean farmers to compete effectively in global markets.
This case examines the environmental permitting process leading up to the construction of the Bui Dam, the second largest hydropower facility in Ghana. Intended to provide much needed relief to the nation’s persistent power challenges, the project secured proper funding from China Exim Bank in 2005, fulfilling several decades of attempts to build the dam. At issue, however, are the potential environmental and social impacts associated with dam construction.
