TL;DR: In this article, the conventional wisdom that post-1950 population growth, leading to extensive deforestation of the Himalayas, is the cause of catastrophic flooding of Bangladesh and northern India is challenged.

TL;DR: Complementarity of in situ (on-farm) conservation with ex situ conservation together with crop improvement in such marginal areas are suggested.
Abstract: There is a growing realisation world over that the introduction of modern agriculture has to be supplemented with measures to conserve biodiversity in situ if yield gains are to be stabilized. Hence, there is a growing interest from agricultural development specialists and conservation biologists for understanding the socioeconomic factors determining the conservation of biodiversity in situ. The present study was conducted with the objective of understanding the in situ (on-farm) conservation of agrobiodiversity in traditional agroecosystems taking the Urgam valley in north-western Himalaya of India, as a case study. An inventory was made of traditional crops and wild economic species for subsistence, and the structure of forest resource base, traditional knowledge related to resource management and use. Institutional and scientific challenges for in situ (on-farm) management of crop diversity were studied and are discussed in this paper. Complementarity of in situ (on-farm) conservation with ex situ conservation together with crop improvement in such marginal areas are suggested.

TL;DR: In this paper, the authors present evolutionary models of food acquisition, and discuss examples of the associated empirical research among humans, focusing on hunter-gatherers and forager-horticulturalists.
Abstract: This chapter presents evolutionary models of food acquisition, and discusses examples of the associated empirical research among humans. The principal focus will be upon hunter-gatherers and forager-horticulturalists with little or no market involvement. The chapter examines subsistence decisions, given the technology and resource acquisition abilities of the people in question. It assesses progress toward the complementary goals of explaining observed variation in diet and food acquisition strategies among and within human groups and developing general models of behavioral decision making. The chapter reviews the application of optimization theory to dietary decisions and the most general foraging models: prey choice, patch choice, and combined prey and patch choice models. It discusses ways in which traditional human economies are likely to violate the assumptions of most existing foraging models, and some areas in which studies of humans are likely to contribute to a general understanding of subsistence behavior in all organisms.

TL;DR: In this paper, a farm programming model was constructed to analyze the impact of marketing strategies on the introduction of new technology in the semiarid region of the Sahel, and the authors found that marketing strategies accelerated the technology introduction process and further increased farmers' incomes.
