Since the 1970s, federal policies promoting migration and encouraging agricultural development of large farms, logging, and ranching have led to the deforestation of vast areas of the Amazon rainforest.Though these policies have largely been replaced, deforestation continues. What effects do current macroeconomic and regional policies and events have on deforestation and on the well-being of settlers on the agricultural frontier?

a synthesis
Documents de politique et mémoiresdécembre, 1995Afrique sub-saharienne, AfriqueThe workshop participants were clear that now is the time for choices, and that without the will to make those choices, the likelihood of success in boosting agricultural growth on a sustained basis would be small. Without such growth, it will not be possible to improve food security or halt natural resource degradation. It seems unlikely that all countries of Africa will choose to put in place the necessary conditions for growth, which makes it all the more important to decide at the outset which conditions are most likely to beget further success.

The previous sections have highlighted the importance of assets as a determinant of bargaining power within marriage. Both formal and informal institutions underlie asset accumulation and provide the basis for property rights. When women face social and legal restrictions in acquiring certain forms of assets, such as land, they may resort to accumulating other “assets” and investing in other forms of capital.

seuls les petits agriculteurs peuvent y parvenir
Documents de politique et mémoiresdécembre, 2003Afrique orientale, Afrique occidentale, Afrique australe, Afrique sub-saharienne, AfriqueContrairement aux prévisions communément admises quant à l’aggravation du déclin économique de l’Afrique, une récente étude présente une vision alternative plus positive de l’avenir de ce continent. De nouveaux engagements politiques, une gestion du programme de développement sous égide africaine ainsi que l’accroissement de l’intérêt et des investissements dans les petites exploitations agricoles ont le potentiel d’arrêter, voire d’inverser la tendance spiroïdale de la famine, de la pauvreté, de la dégradation environnementale, des maladies et des guerres civiles.

only the small farmer can do it
Documents de politique et mémoiresdécembre, 2002Afrique orientale, Afrique occidentale, Afrique australe, Afrique sub-saharienne, Afrique"In contrast to popular predictions of Africa’s worsening economic decline, recent research supports an alternative and more positive vision of Africa’s future. New political commitment and African ownership of the development agenda, combined with a renewed focus on and investments in smallholder-led agriculture, have the potential to halt or reverse the current downward spiral of hunger, poverty, environmental degradation, disease, and civil strife.

"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).

The impressive growth in aquaculture is now commonly dubbed a “blue revolution.” In some Asian countries, fish availability has increased at a faster rate in recent decades than did cereal availability during the Green Revolution. As an example, Bangladesh is one country where aquaculture has increased almost eightfold since the early 1990s. This growth has important implications for food and nutrition securities. Yet, there is little research on the determinants and impacts of this growth to document the lessons, identify evolving issues, and guide policy discussions.

Climate change projections internationally accepted as being reliable indicate that most countries in the Pacific region will suffer large-scale negative impacts from climate change. These impacts are likely to include elevated air and sea-surface temperatures, increasingly unpredictable rainfall patterns, rising sea levels, and intensification of extreme weather events such as tropical cyclones and El Niño-related droughts.

For decades, policymakers and development practitioners have debated benefits and threats of property rights formalization and private versus customary tenure systems. This paper provides insights into the challenges in understanding and empirically analyzing the relationship between tenure systems and agricultural investment, and formulates policy advice that can support land tenure interventions. We focus on Ghana, based on extensive qualitative fieldwork and a review of empirical research and policy documents.
