El objetivo de este estudio fue identificar opciones que permitan mejorar la productividad caprina en una microcuenca con dos poblados en las regiones áridas del norte mexicano. El estudio se realizó durante los años 2004 al 2007 y se basó en el enfoque de sistemas de producción. Se evaluaron aspectos socioeconómicos y ecológicos al nivel de macrosistema para identificar diferencias socioeconómicas y con posibles opciones generadoras de ingresos, y determinar la idoneidad del área para producir cabras e identificar tierras bajo cultivo que pudieran reconvertirse en tierras de pastoreo.
The agro-ecosystem is a system composed of population, natural resources and economic activities related in a dynamic interaction in terms of socio-ecological and socio-economic relations conditioned by endogenous and exogenous factors. With time, the agro-ecosystem undergoes changes. By analysing the agro-ecosystem dynamics over a period of time, we can plan the agro-ecosystem for higher level of production and productivity, achieving higher level of resource use and environmental efficiency and maximise food security as well as livelihood security.
The latest turmoil of production and price volatility in the global food sector has put agriculture back to the top of the development agenda. Population growth, changing consumer preferences, bioenergy demand and climate change are some of the huge challenges for agricultural production today and in the future. In the last decades, productivity has been constantly improved through the introduction of improved crop varieties and the greater use of mechanization, irrigation, chemical fertilizer and pesticides.
Various indications that research and development efforts are escalating in developing countries indicate the slight shift of such countries from just being end markets to being developers. The aggregate adoption of biotech crops in developing countries is clearly approaching that in developed countries. The next generation biotech crops with superior traits, with improved properties and quality traits will likely be created and deployed in developing countries, particularly in Asia, where half of the world’s population dwells.
Recent studies in the literature examining impact of government seed price intervention on adoption of Bt cotton get different results depending on the specifics of the situation analyzed. According to one study, reduction in seed prices enables farmers to buy seeds at lower prices and this can result in surge of area sown under Bt cotton. The other view holds that seed price interventions have little impact on the adoption rates rather these interventions may adversely affect firms’ incentives to innovate. Which of the two views characterize adoption of Bt cotton in India?
LenCD has prepared a joint statement on results and capacity development (presented in this publication), which stresses that meaningful, sustainable results are premised on proper investments in capacity development and that these results materialize at different levels and at different times, along countries’ development trajectory. To provide evidence in support of this statement, LenCD launched a call for submission of stories.
This report is organized into nine chapters. Chapter one provides the introduction to the report. Chapter two presents alternative approaches to agribusiness development and chapter three discusses the role of agribusiness incubators. Chapter four discusses the challenges of agribusiness incubators and chapter five presents a typology of agribusiness incubators. Chapter six elaborates on the evolution of incubators over time. Chapter seven presents the analysis of impact and cost-benefits. Chapter eight summarizes good practices and lessons learned.
Tanzania has tremendous potential to support a thriving agribusiness sector. Agriculture is diverse and extensive, employing more than 80 percent of the population, and contributing about 28 percent of Gross Domestic Product, or GDP and 30 percent of export earnings. A wide range of agricultural commodities are produced in Tanzania, including fiber (sisal, cotton), beverages (coffee, tea), sugar, grains (a diverse range of cereals and legumes), horticulture (temperate and tropical fruits, vegetables and flowers) and edible oils.
Interest in farmland is rising. And, given commodity price volatility, growing human and environmental pressures, and worries about food security, this interest will increase, especially in the developing world. One of the highest development priorities in the world must be to improve smallholder agricultural productivity, especially in Africa. Smallholder productivity is essential for reducing poverty and hunger, and more and better investment in agricultural technology, infrastructure, and market access for poor farmers is urgently needed.
The World Bank Group has a unique opportunity to match the increases in financing for agriculture with a sharper focus on improving agricultural growth and productivity in agriculture-based economies, notably in Sub-Saharan Africa.
