A Meta Analysis Of Rates Of Return To Agricultural R D

Analyze alternative national and international strategies and policies for meeting foof needs of the developing world on a sustainable basis, with particular emphasis on low-income countries and on the poorer groups in those countries.

This annual report monitors and evaluates agricultural policies in 54 countries, including the 38 OECD countries, the five non-OECD EU Member States, and 11 emerging economies. This year’s report focuses on policy responses to the COVID-19 pandemic and analyses the implications of agricultural support policies for the performance of food systems.

Recent mergers in the seed industry have led to concerns about market concentration and its potential effects on prices, product choice, and innovation. This study provides new and detailed empirical evidence on the degree of market concentration in seed and GM technology across a broad range ...

This report presents the latest updates related to food security and nutrition in Europe and Central Asia, including estimates on the cost and affordability of healthy diets. It also explores how governments are supporting the food and agriculture sector and how to repurpose policies and incentives to make healthy diets more affordable and agrifood systems more environmentally sustainable. The new estimates confirm that the prevalence of hunger at chronic or severe levels is relatively low in the ECA region, through the prevalence of food insecurity at moderate or severe levels can be quite high. The region is seeing alarmingly high – and rising – rates of overweight and obesity. The COVID-19 pandemic has added 25.5 million people in the region to the ranks of the moderately or severely food insecure, leaving them without access to safe, nutritious and adequate food. The war in Ukraine has made the situation worse. Almost all ECA subregions are experiencing increased costs and reduced affordability of healthy diets because of higher food prices and lower incomes. This report contains an in-depth analysis of the repurposing of food and agricultural policies to ensure the food systems transformation is better suited to addressing the “triple challenge” of achieving food security and good nutrition for better health, providing livelihoods to farmers and others connected to the sector, and reducing the nature and climate footprint of the sector. This report also reviews complementing policies within and outside of agrifood systems to assess whether repurposing efforts are impactful in the ECA region.

This report explains why Southeast Asian countries need to design pandemic recovery policies that hit both ambitious socioeconomic and environmental goals. The third in a four-part series, the report considers the impact of COVID-19 on Cambodia, Indonesia, Myanmar, the Philippines, and Thailand to show how a green recovery can help safeguard against future health crises. Analyzing areas including agriculture, cities, and oceans, the report lays out policy measures designed to identify, create, and finance green growth opportunities. It shows how COVID-19 has presented countries with a chance to hit the reset button and build a socially, economically, and environmentally resilient future.

This volume is written primarily for agricultural economists doing research on productivity. It includes discussions of the theoretical underpinnings of productivity measurement as well as the many practical considerations that go into translating this theory into actual measures of aggregated outputs and inputs. The unifying concept of agricultural productivity used across the chapters of this volume is aggregate total factor productivity (TFP) of the sector. The volume also contains detailed analysis of the underlying causes of agricultural productivity growth. Part I (chapters 2-6) examines agricultural productivity in high-income and transition countries. Part II (chapters 7-11) examines agricultural productivity growth and its driving forces in five important agricultural producers in Asia and Latin America. Part III (chapters 12-14) focuses on measuring and identifying constraints to agricultural productivity growth in sub-Saharan Africa. Part IV (chapters 15-16) gives a global perspective on agricultural productivity.

Since 1985, the Chinese government has given high priority to building roads, particularly high-quality roads that connect industrial centers. This report evaluates the contribution roads have made to poverty reduction and economic growth in China over the last two decades. It disaggregates road infrastructure into different classes to account for differences in their quality, and then estimates the impact of road investments on overall economic growth, agricultural growth, urban growth, urban poverty reduction, and rural poverty reduction. The report makes the case for a greater focus on low-quality and rural roads in future infrastructure investment strategies in China. It does so by showing how investing in low-quality and rural roads will generate larger marginal returns, raise more people out of poverty per yuan invested, and reduce regional development disparity more sharply than investing in high-quality roads. The study's findings will have considerable implications for China's infrastructure policy
