| Fertile land and fresh water constitute two of the most fundamental resources for food production. These resources are affected by environmental, political, economic, and technical developments. Regional impacts may transmit to the world through increased trade. With a global forest and agricultural sector model, we quantify the impacts of increased demand for food due to population growth and economic development on potential land and water use. In particular, we investigate producer adaptation regarding crop and irrigation choice, agricultural market adjustments, and changes in the values of land and water. |

| Soil fertility and the lack of fertilizer use in Africa are frequently discussed topics. The problems of land degradation and low agricultural productivity, which result in food insecurity and poverty, are particularly severe in the rural highlands of Ethiopia. In many areas, a downward spiral of land degradation and poverty appears to be occurring. Finding solutions to these problems requires identifying effective entry points for farmers, governments, and civil society organizations, and understanding the potential impacts and tradeoffs that are likely to arise from alternative interventions. This report seeks to improve that understanding, using a bioeconomic model of land management and agricultural production developed for a community that is fairly... |

| Modernization of traditional agriculture entalls increased participation of the smallholder sector in the exchange economy. The achievement of this participation requires an open trade regime, domestic policies that ensure against market failures and public policy that effectively permits use of a new production technology for sustained growth. To open up these opportunities to small farmers, investment in rural intrastate is essential, as is investment in education that will enable these farmers to participate as entrepreneurs in the growth process must stimulate employment and increased returns to land. Nontraditional vegetables for export have a higher labor content and therefore promise to help foster rural modernization. In this study of... |

| The economic impact of globalization, particularly on poverty, and the changes in agri-food markets have received much attention in recent years. However, the intersection of these two trends has been neglected. The present volume fills this gap by focusing on the way globalization of agri-food systems affects the world’s poor and its impact on food and nutrition security in developing countries. Rather than offering a single policy prescription or simplistic messages about globalization being 'good' or 'bad', the book acknowledges the complexity of the subject by including a variety of policy and research perspectives. The contributors analyse in details the links between poverty and globalization. They examine the different interactions between the... |

| With its focus in irrigation technology and commercialization of rice in West Africa, this study addresses the question of how agricultural growth in Sub-Saharan Africa may improve food security. Over the last few decades in Africa, rice has ranked second after maize among cereal that have contributed to the overall growth of cereal output. In West Africa, rice imports have grown rapidly during the last two decades. Future decisions on irrigation investments and technology choices will be critical importance in view of numerous past failures and excessive costs of irrigation in Sub-Saharan Africa. This research by Joachim Von Braun, Detlev Puetz, and Patrick Webb is to be seen against the backdrop of policy priorities resulting from the earlier work of... |

| Success in ensuring a continuous, adequate supply of food is one of the most important bases on which governments of low-income countries are judged by their people. This is because downward fluctuations in food supplies wreak great privation on low-income people and redistribute real income away from them. In view of this, the International Food Trade and Food Security Program at the International Food Policy Research Institute (IFPRI) has undertaken a series of studies of food supply management in developing countries. Among the policies considered have been schemes to compensate for fluctuations in food production and supply and in foreign exchange availability at the national, regional, and international levels. IFPRI's studies of food management... |

| The role of agriculture in India’s economic development continues to be of great importance, as a producer of food, as an employer of about two-thirds of the labor force, and as a source of purchasing power for much of the nonagricultural consumer goods and services in the economy. Thus, rapid growth in agricultural is essential for sustainable growth and development of the economy. Within agriculture, foodgrain production is by far the major activity, covering about 80 percent of the cropped area in India and providing the main staple source of food. Foodgrains provide almost all the calories and proteins consumed by the poor and provide the rural poor with the bulk of their employment and income. Further, with a population of some 800 million people,... |

| Poverty reduction is one of the overarching objectives of most of Sub-Saharan Africa and other low-income countries. Accordingly, one of IFPRI’s major research themes focuses on policies and strategies for poverty reduction. This research report contributes knowledge to that theme. It also contributes to IFPRI’s ongoing investigation of policies and strategies that foster broad-based and environmentally sustainable agricultural and rural development. In Uganda, where soil erosion and depletion of soil nutrients are widespread, land degradation is a major cause of declining productivity and increasing poverty. In this study, Ephraim Nkonya and his colleagues measure the relative merits of various household income strategies and land management practices in... |

| Descriptions of Sciurus ingrami Thomas, 1901 nests are not available in the literature. In this study, a survey was made of the distribution of S. ingrami nests in a woodlot located near to the headquarters of the Serra do Caraça Reserve, in state of Minas Gerais, where there is a high concentration of Syagrus romanzoffiana (Chamisso) Glassman palm tree, among other exotic tree species. The nest-building behaviour and the nest characteristics, such as height from the ground, total circumference, diameter of the entrance, and the position of the nest in the tree - in the crown, along the trunk or in a side branch, were described. |

| The amount of carbon dioxide (CO2) of the Earth´s atmosphere is increasing, which has the potential of increasing greenhouse effect and air temperature in the future. Plants respond to environment CO2 and temperature. Therefore, climate change may affect agriculture. The purpose of this paper was to review the literature about the impact of a possible increase in atmospheric CO2 concentration and temperature on crop growth, development, and yield. Increasing CO2 concentration increases crop yield once the substrate for photosynthesis and the gradient of CO2 concentration between atmosphere and leaf increase. C3 plants will benefit more than C4 plants at elevated CO2. However, if global warming will take place, an increase in temperature may offset the... |
