This book creates a scientific base for the development and testing of sustainable production and land use systems in ecologically fragile and economically disadvantaged mountainous regions in Southeast Asia; to develop concepts for rural institutions that can reduce rural poverty and food insecurity, and improve livelihoods in mountainous regions in Southeast Asia; and to explore methods for analyzing complex ecosystems and their interactions with the socio-cultural, economic and institutional environment.
Agricultural development research aims to generate new knowledge or to retrieve and apply existing forms of knowledge in ways that can be used to improve the welfare of people who are living in poverty or are otherwise excluded, for instance by gender-based discrimination. Its effective application therefore requires ongoing dialogue with and the strong engagement of men and women from poor marginal farming communities. This book discusses opportunities afforded by effective knowledge pathways linking researchers and farmers, underpinned by participatory research and gender analysis. It sets out practices and debates in gender-sensitive participatory research and technology development, conc...

Pectins are one of the classes of complex structural plant cell wall polysaccharides. They are localized in the middle lamella and primary cell wall of higher plants. Pectins have a long-standing use as gelling agents whereas their enzymatic degradation or modification plays an important role in the processing of agricultural crops and the manufacturing of foods and beverages. Progress in pectin and pectinase research has been most prominent in two areas over the past 5 years. The first one concerns the analysis and elucidation of the complex chemical structure of pectin and identification of novel enzymes involved in the degradation of these structures. The second area concerns the mode of ...
