Agrobiodiversity conservation is vital for achieving sustainability, but empirical studies on the effects of different practices or measures on crop diversity are rare. This study aims to estimate the effects of raising conservation awareness (RCA), building diversity blocks (BDB), and their combination on crop diversity among 240 randomly selected households surrounding the Rupa Lake Watershed in Nepal. Based on descriptive analysis and multiple regression models, the results indicate that the two single measures had no significant effect on the numbers of crop species and varieties grown by households in 2018. However, the combination of RCA and BDB had a significantly positive effect on the number of crop varieties, especially for grain and vegetable crops. Considering that these crops are essential in the daily lives of local people, the results indicate that a strategy that combines both awareness raising and on-farm conservation measures can generate higher crop diversity and better serve the climate-resilient livelihoods of people in mountainous areas.

A watershed consists of more than two regions intending to apply ecological compensation to solve the transboundary pollution problems. For this purpose, we develop a differential game model to investigate each region's optimal strategy and show the following main conclusions: (1) There is a set of optimal ecological compensation rates that improve the welfare of each region and produce Pareto improvement results. (2) Ecological compensation shifts partial pollution reduction investments from downstream to upstream regions and increases total reduction investments in the basin. (3) Ecological compensation improves the water ecosystem and increases each region's yield and income level.
