La demanda de biocombustibles se está incrementando debido a la necesidad cada vez mayor de energéticos, el alza en el costo del petróleo, la búsqueda de fuentes de energía renovables y no contaminantes y el deseo de aumentar los ingresos agrícolas en los países en desarrollo. Asimismo, ha aumentado en forma drástica la necesidad de contar con cultivos, como el maíz y la caña de azúcar, que pueden utilizarse como materia prima para producir biocombustibles. Esta demanda ha tenido a nivel mundial un impacto significativo y cada vez mayor en los sistemas alimentarios.

High food prices are not only causing a humanitarian crisis, but also putting at risk the development potential of millions of people. Global agriculture markets are undergoing structural changes, and the next three to four years will pose great challenges for achieving an affordable and accessible food supply for the world's most vulnerable. Soaring food and fuel prices are creating a "perfect storm" for the world's most vulnerable.

"Part of the difficulty in responding to the food crisis is the lack of credible and up-todate data on the impacts of food prices on poor people and on the effects of policy responses. Such information would allow international and national decision makers to use feedback to adjust their responses and achieve maximum effectiveness. Much more investment and sound coordination is needed in this area. So far, national and international responses to the food crisis are mixed in terms of their likely effectiveness.

In 2008, a year in which the global population—particularly the world’s poor—was confronted by both the financial and food-price crises, agricultural systems faced changes that led to market disruptions, reduced growth, mass protests, and a string of political efforts to reshape the design and governance of food systems.

"The dramatic rise and volatility of food prices over the last year have shaken the global food system. Governments and the international development community generally have responded to various aspects of the food crisis, but questions remain about whether the right actions are being pursued, how best to respond, and what the future holds.

El dramático aumento y la volatilidad de los precios de los alimentos durante el último año han sacudido al sistema alimentario mundial. Por lo general, tanto los gobiernos como la comunidad dedicada al desarrollo internacional han respondido ante diversos aspectos de la crisis alimentaria, pero todavía permanecen las preguntas sobre si se han tomado o no las acciones más adecuadas, cuál es la mejor forma de responder y qué nos aguarda en el futuro.

The report includes three essays about Responding to the World Food Crisis: Getting on the Right Track by Joachim von Braun, High Global Food Prices: The Challenges and Opportunities by Josette Sheeran, and Policy Implications of High Food Prices for Africa by Namanga Ngongi.

Fisheries are complex and interdependent ecological and social systems that require integrated management approaches. The actions of one person or group of users affect the availability of the resource for others. Managing such common pool resources requires conscious efforts by a broad range of stakeholders to organize and craft rules enabling equitable and sustainable use of the resources for everyone?s benefit. Collective action is often a prerequisite for the development of community-based institutions and the devolution of authority...

In this brief, we explore the role that social institutions -specifically property rights and collective action - may play in the development of agroforestry.... In the future, property rights and collective action will play increasingly pivotal roles in defining rights and responsibilities over the externalities of tree management practices.

"This paper describes the emergence of improved traditional planting pits (zaï) in Burkina Faso in the early 1980s as well as their advantages, disadvantages and impact. The zaï emerged in a context of recurrent droughts and frequent harvest failures, which triggered farmers to start improving this local practice. Despair triggered experimentation and innovation by farmers. These processes were supported and complemented by external intervention. Between 1985 and 2000 substantial public investment has taken place in soil and water conservation (SWC).

Floodplain wetlands are the major common pool natural resource in Bangladesh. Mostly men fish, and both men and women collect aquatic plants and snails. Case studies contrast a women-only, men-only, and mixed community based organization (CBO), each of which manages a seasonal floodplain wetland. The two CBOs in which women hold key positions are in Hindu communities where more women use aquatic resources, work for an income, and belong to other local institutions. In the oldest of these CBOs, more women have gradually become office bearers as their recognition in the community has grown.
