An ex ante evaluation of factors affecting farmers' land use is presented, using surveyed data gathered from low-income maize and vegetable farmers in a southern Philippines watershed at the forest margin to measure how land and labour allocations for various crops respond to changes in expected...

This chapter covers the history of integrated pest management (IPM), organizational structure of IPM, pesticide policy, IPM application in major crops (rice, maize and cabbage), impact of KASAKALIKASAN (an IPM programme with farmers as the main participants) on agricultural production, and...

This chapter covers the following aspects of the Integrated Pest Management Collaborative Research Support Program (IPM CRSP): background, organizational and operational structure, mode of collaboration, participatory rural appraisal process, annual work plan development and its implementation,...

Results are presented of field experiments during 1998-2003 in the Manupali River Watershed (Mindanao, Philippines) designed to evaluate tree-based (Eucalyptus grandis) and improved fallow (sunflower and Tithonia diversifolia) production systems with annual crops (tomato, maize, beans [Phaseolus]...

This chapter explores land use decisions made by farmers in the upper Manupali watershed, Philippines. A panel of farm-level data (1994-2002) is used to quantify responses to economic shocks, and thereby to understand the leverage that policies affecting agricultural prices can be expected to exert ...

This chapter presents a framework for measuring the changes in economic and environmental outcomes that occur in watersheds subject to land degradation, both in partial and in general equilibrium. This framework is used to calculate changes in upland land degradation due to changes in economic...

This chapter provides a case study of the eventual approval of Bt maize in the Philippines amidst a contentious environment. This case study of the commercialization of Bt maize in the country demonstrates the crucial role of science communication in technology development and acceptance. The...

This chapter discusses the various ways the system of shifting cultivation has been modified to make it a more intensive system of agriculture. Attempts to modify shifting cultivation include the integration of trees into farmlands to form agroforestry systems, enrichment of fallow vegetation with...

Fungal diversity plays a vital role in sustaining human life, either benefiting or threatening food security. Benefits that derive from fungi range from food and medicine, to decomposition of organic matter, recycling of nutrients and as plant growth promoters, including biological control of...
