Drip irrigation has received considerable attention from policy makers because of its significant contribution towards resource saving, enhanced agricultural productivity and environmental sustainability. This paper explores the potential benefits of drip irrigation adoption by addressing the social benefits and costs in Southern India. The study shows that adoption of drip irrigation technology has resulted in significant external and private benefits. The social benefit–cost ratio (SBCR) ranged from 4.33 to 5.19 at a 2% discount rate under different scenarios across regions. This confirms that a wide adoption of drip irrigation produces sufficient social benefits to justify the subsidization of drip irrigation. Water management policy should focus attention on the promotion of drip irrigation in regions where water and labour scarcity are critical.

Community-based Forestry (CBF) is now a popular approach for landscape restoration, forest management, biodiversity conservation and support for rural livelihoods worldwide. The Himalayan country Nepal has been at the forefront of CBF for over four decades, with almost 40% of the total population directly involved in protecting and managing more than 32% of the country’s forested land. However, in the past, the focus of CBF in Nepal was the provision of goods for local subsistence, and there has been limited analysis of the role of CBF in providing ecosystem services (ES) from restored forest landscapes. Based on material drawn from a literature review and a stakeholders’ workshop, this paper analyses changes in Nepalese forest policies to provide a more holistic framework for CBF that provides a wider range of ES and to potentially underpin payments for ecosystem services in Nepal. The analysis indicates that Nepal’s forest policy and practices are still dominated by a narrowly conceived notion of forest management that does not accommodate the holistic concept of ES. The study illustrates that CBF provides many ES from local to global benefits as result of forest restoration. For example, timber, firewood, food, and water have local importance, while climate regulation, flood/erosion control, and habitat improvement have global importance. Many innovative cases are emerging in the long journey of CBF in Nepal that demonstrate more diverse management strategies, new forms of tenure rights and autonomy in institutional spaces. These can potentially provide a catalytic platform for the wider adoption of the ES framework in CBF regimes, in order to focus and reward forest management more directly for the provision of services such as water, biodiversity, climate regulation and recreation. Consequently, this study discusses the issues and challenges that are impeding the implementation of the ES concept in Nepal and suggests some ways forward.

Black soldier fly colonies can produce about 100 times more protein per year than chicken or soybeans, not to mention cattle, on the same area of land. The flies can directly feed on different types of organic wastes, leapfrogging closed loop processes within a circular food economy. Also, where no protein is needed, for example, to feed fish or pigs, the larvae can be processed into high-quality biodiesel. However, can this be done at scale? The answer is ‘Yes’. The report showcases some of the leading global businesses in Black Soldier Fly production.
