    摘要、提要註: The northern Indian landscape in Uttar Pradesh state has an agricultural history of over 10,000 years, and has been converted to a high human-density smallholder farmland for many centuries now. Biodiversity conservation in such areas is challenging due to habitat attrition, and a high degree of human disturbance. In recent years, conservation is compounded by changing climate. Few tropical agricultural areas with long agricultural histories have been explored under assumptions they are species depauperate dominated by synanthropes (species reliant on humans activity). Understanding drivers of species populations, species richness and abundance on such landscapes can provide insights to maximize species persistence and aid in increasing species richness and abundance. In this dissertation, I explore the relative importance of habitat attrition and changes in rainfall patterns on breeding success and long-term population viability of two large waterbird species of conservation concern using an eight-year data set from south-western Uttar Pradesh (Chapter 1). Analyses underscore the importance of wetlands retained by farmers to improve breeding success, and sensitivity analyses unambiguously identified land conversion to development as being the most important factor that requires being controlled to ensure long-term large waterbird persistence on the landscape. I also explore factors influencing modelled multi-season occupancy for 56 resident bird species across 24 districts and highlight the importance of remnant habitat and low agricultural intensification for persistence of resident species (Chapter 2). Remnant habitat is important to improve occupancy of birds especially those of wetland and woodland guilds, and a landscape-scale approach to conservation is required to maximize species persistence in Uttar Pradesh. I provide the first high-resolution distribution maps for the species analysed. Finally, I assess in detail the drivers of bird species richness, abundance of five habitat guilds, and abundance of 30 species across three seasons in 24 districts using explanatory variables across three spatial scales (Chapter 3). I showcase complex seasonal patterns of abundance-variables associations that result due to seasonal variations in crops, demonstrate the relatively high species richness of largely non-synanthropic species persistent on the landscape, and underscore the importance of habitat patches retained by farmers for common use to maximize abundance of birds in Uttar Pradesh. Smallholder farms comprise one-third to half of all farmlands, and are largely ignored by conservationists who assume they are of low conservation importance. My thesis underscores the need to provide better coverage of landscapes with smallholder farming. Dominant existing strategies to enable biodiversity conservation in agricultural landscapes are economic compensation to farmers, and increasing set-aside areas. Including locally relevant strategies, such as the traditional retaining of habitat patches for community use, alongside other used techniques will enable greater efficiency in reconciling biodiversity conservation alongside agriculture globally.
