Dynamic Agricultural Household Bio-Economic Simulator (DAHBSIM) model description


Book Description

DAHBSIM is a dynamic, bio-economic model of agricultural households that was designed to be applied to a rural, developing country-setting, for the purpose of addressing questions around the biophysical constraints to on-farm agricultural productivity, and the whole-farm implications of alternative strategies to sustainable agricultural intensification. The model links socio-economic and biophysical aspects, in order to better illustrate the environmental and human welfare implications of different agricultural production practices, as they are influenced by policy-driven changes in prices of inputs or outputs, or by changes in the physical environment.




Agricultural Input Subsidies


Book Description

This book takes forward our understanding of agricultural input subsidies in low income countries.




Sustainable Intensification


Book Description

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.







Strategies and Priorities for African Agriculture


Book Description

In the first decade of the twenty-first century, countries within Sub-Saharan Africa reached milestones that seemed impossible only ten years ago: macroeconomic stability, sustained economic growth, and improved governance. Continuing this pattern of success will require enhancing the region’s agricultural sector, in which a large proportion of poor people make a living. The authors of Strategies and Priorities for African Agriculture: Economywide Perspectives from Country Studies argue that, although the diversity of the region makes generalization difficult, increasing staple-crop production is more likely to reduce poverty than increasing export-crop production. This conclusion is based on case studies of ten low-income African countries that reflect varying levels of resource endowments and development stages. The authors also recommend increased, more efficient public investment in agriculture and agricultural markets and propose new directions for future research. The last ten years have been an encouraging time for one of the world’s poorest regions; this book offers an analysis of how recent, promising trends can be sustained into the future.







The Role of Smallholder Farms in Food and Nutrition Security


Book Description

This open access book discusses the current role of smallholders in connection with food security and poverty reduction in developing countries. It addresses the opportunities they enjoy, and the constraints they face, by analysing the availability, access to and utilization of production factors. Due to the relevance of smallholder farms, enhancing their production capacities and economic and social resilience could produce positive impacts on food security and nutrition at a number of levels. In addition to the role of small farmers as food suppliers, the book considers their role as consumers and their level of nutrition security. It investigates the link between agriculture and nutrition in order to better understand how agriculture affects human health and dietary patterns. Given the importance of smallholdings, strategies to increase their productivity are essential to improving food and nutrition security, as well as food diversity.




The Future of Philippine Agriculture under a Changing Climate


Book Description

The Philippine economy has grown rapidly since 2010, but despite this growth, poverty and inequality remain high. Two-thirds of the poor live in rural areas, and the weak performance of the agriculture sector has contributed to the slow improvement in livelihoods. The challenge for agriculture will further increase, with climate change posing a growing threat to the sector. But agricultural transformation to spur sustained growth and reduce poverty is still possible under climate change with aggressive institutional reforms and implementation of the right mix of policies and programmes. The identification of the suitable policy and programme combination requires an accurate assessment of the key drivers of agricultural growth and food security; the impacts of climate change on agriculture and the overall economy; and the effectiveness of policies for adaptation and growth. This book addresses these big issues, focusing on enhancing the adaptation capacity of the Philippine agriculture sector. It is designed to provide a much-needed base of knowledge and menu of policy options to support decision- and policymaking on agriculture, climate change, and food security. The volume uses newly generated data, modelling outputs, and innovative analyses to provide a scientific basis for a variety of adaptation measures under different sets of climate change scenarios to guide decision-makers in strategic planning and policy formulation. “As we have actually experienced in Leyte, an island province in the Visayas where Super Typhoon Yolanda (Haiyan) struck, disasters caused by natural hazards could completely negate economic gains, devastate families and shatter dreams. Our greatest challenge is to make ourselves better prepared for and be more resilient to such disasters. Natural hazards need not always lead to loss of so many lives and properties. This book shows us ways and provides tools to draw up climate change and socioeconomic scenarios at the regional and provincial levels, allowing us to identify strategies for mitigating climate change risks.” — Ernesto M. Pernia, Secretary of Socioeconomic Planning, National Economic and Development Authority, Philippines “This book by top Philippine researchers combines state-of-the-art biophysical and economic modeling of climate impacts and adaptation policies with in-depth synthesis of agriculture, natural resources, climate trends, and policies. It provides a comprehensive assessment of climate change impacts on agriculture and the broader economy to provide important insights for Philippine policymakers.” — Dr Cynthia Rosenzweig, Head, Climate Impacts Group, NASA Goddard Institute for Space Studies and Co-Founder of the Agricultural Model Inter-comparison and Improvement Project (AgMIP)




Quantitative foresight modeling to inform the CGIAR research portfolio


Book Description

This report provides a quantitative assessment of the impacts of alternative investment options on the CGIAR’s SLOs (relating to poverty – SLO1, food and nutrition security – SLO2, and natural resources and ecosystem services – SLO3) in the context of changes in population, income, technology, and climate to 2050 as well as for key SDGs of importance to the developing world. The report serves as a source of information and evidence of the impact of CGIAR efforts in agricultural R&D as well as the role of complementary investments. It is intended to help the CGIAR Centers, CG Research Programs (CRP), system management, and donors to complement other efforts to assess the overall impact and benefits of investing in international and national agricultural research programs.




Practical Applications of Agricultural System Models to Optimize the Use of Limited Water


Book Description

Completely devoted to applicati on of models to opti mize the use of limited water and nutrients in various climates, this collecti on will inspire confi dence in the capacity of modeling to tackle the biggest threats to secure agriculture. To obtain the most producti on from available water while maintaining natural resources, we need whole system–based quanti tati ve knowledge and tools to help select appropriate crops and manage water and associated inputs on a site-specifi c basis under changing climate. Site-specifi c experimental results are available for limited locati ons, limited periods of ti me, and limited management opti ons. Well-tested process models of cropping systems can extend fi eld research results to long-term weather conditi ons, as well as other climates and soils, allowing us to explore new management opti ons. The case studies in this volume are promising examples of these kinds of soluti ons.
