ASTI global assessment of agricultural R&D spending

Overall, global agricultural R&D spending in the public and private sectors steadily increased between 2000 and 2008. As further proof of positive development, most of this growth was driven by developing countries, since growth in high-income countries stalled. But, spending growth in developing countries was largely driven by positive trends in a number of larger, more advanced middle-income countries—such as China and India—masking negative trends in numerous smaller, poorer, and more technologically challenged countries. Countries in this last group are often highly vulnerable to severe volatility in funding, and hence in spending, which impedes the continuity and ultimately the viability of their research programs. Many R&D agencies in this group lack the necessary human, operating, and infrastructural resources to successfully develop, adapt, and disseminate science and technology innovations.

Looking Ahead in World Food and Agriculture

Fuelled by the turbulence of world agricultural markets, the debate on relations among agriculture, food security, natural resources, population growth and economic development has been revamped over the last few years. how are growth prospects and the expected evolution of per capita income in the long term going to affect the agricultural and food economy? Are the natural resources available, such as land and water, sufficient to feed a growing population? What role can economic incentives and technical change play in shaping resource use and supply? What are the priority areas where investment and research should be directed? How may the use of agricultural products in biofuel production affect markets? And how can climate change affect production possibilities and markets? Around these questions, in 2009, FAO’s Economic and Social Development Department organized a Forum and a High-Level Expert Meeting on How to Feed The World in 2050. This volume follows up on that initiative, by gathering updated versions of technical materials prepared for the occasion, along with further work. the book seeks to sustain the debate on the future of the global agricultural and food economy. Its contents were designed to interest both a technical audience and a wider range of professionals working around the world in areas related to agriculture, in both public and private institutions

Agricultural Policy Impact Analysis with Multi-Market Models: A Primer

Many governments intervene directly in agricultural product, in particular food, markets. A quantitative assessment of the impact of the policy changes on the desired objectives is important as it helps inform and shape the policy debate on the reform alternatives and increases transparency of government policy. This paper reviews the literature on multi-market models which offer more accurate ex ante impact analysis than single-market models by including potentially important indirect effects. While fairly complex and requiring large amounts of data multi-market models are however much simpler than computable general equilibrium models. They are typically applied at the sector level and have proven quite popular in particular in agricultural policy reform impact analysis. While more recent work has emphasized the poverty reduction and income distribution objective the models can generate a range of information relevant to policy makers. Key Words: Multi-market models, agricultural policy impact analysis.

A new index to assess soil quality and sustainability of wheat-based cropping systems

Sustainability index was calculated to assess soil quality under the influence of different fertilizer management practices. It is based on the area of the triangle in which nutrient index, microbial index and crop index of soil represented the three vertices of a triangle. Nutrient index reflected the nutrient status of soil and was calculated from the measurements of various soil chemical parameters. Microbial index was calculated by determining various soil microbial and biochemical activities and crop index by measuring of crop yield parameters. Eighteen soil indicators were determined to assess nutrient index, microbial index and crop index in order to compare the effect of different sources of nutrients such as green manure, farmyard manure and chemical fertilizer in a rice/corn– wheat rotation. The indices were applied to assess the sustainability of five field experiments with respect to the different fertilizer treatments. The long-term application of organic manures in rice/corn–wheat cropping system increased the index value because it increased the nutrient index, microbial index and crop index of soils. The use of only chemical fertilizers in the rice–wheat cropping system resulted in poor soil microbial index and crop index. In corn–wheat system, additional application of FYM at 10 t ha−1 before sowing corn made the system more sustainable than application of 100%NPK; the sustainability index values were 2.43 (the highest for this system) and 0.93, respectively.
