Island Southeast Asia has recently produced several surprises regarding human history, but the region’s complex demography remains poorly understood. Here, we report ∼2.3 million genotypes from 1,028 individuals representing 115 indigenous Philippine populations and genome-sequence data from two ∼8,000-y-old individuals from Liangdao in the Taiwan Strait. We show that the Philippine islands were populated by at least five waves of human migration: initially by Northern and Southern Negritos (distantly related to Australian and Papuan groups), followed by Manobo, Sama, Papuan, and Cordilleran-related populations. The ancestors of Cordillerans diverged from indigenous peoples of Taiwan at least ∼8,000 y ago, prior to the arrival of paddy field rice agriculture in the Philippines ∼2,500 y ago, where some of their descendants remain to be the least admixed East Asian groups carrying an ancestry shared by all Austronesian-speaking populations. These observations contradict an exclusive “out-of-Taiwan” model of farming–language–people dispersal within the last four millennia for the Philippines and Island Southeast Asia. Sama-related ethnic groups of southwestern Philippines additionally experienced some minimal South Asian gene flow starting ∼1,000 y ago. Lastly, only a few lowlanders, accounting for <1% of all individuals, presented a low level of West Eurasian admixture, indicating a limited genetic legacy of Spanish colonization in the Philippines. Altogether, our findings reveal a multilayered history of the Philippines, which served as a crucial gateway for the movement of people that ultimately changed the genetic landscape of the Asia-Pacific region.

This paper examines the effective practices and constraints of community-based forest management enterprises (CBFEs) in Nepal in providing income benefits to the poor. The tenure reform clarity and strengthening of tenure rights at community level through various CBFM programs in Nepal in the last few decades has enhanced opportunities for the rural people to benefit from forest-based enterprises. However, a key concerns as these programs have advanced over the years has been whether the poor benefit from them given their high dependence on the forests. To examine this question, 28 CBFE from Nepal's mid-hills and mountain districts were selected purposively from among forest user groups (FUGs) engaged in income-generating activities, varying in their size of membership, use of forest products and stage of growth. These CBFEs have been broadly categorised into FUGs, networks, cooperatives and companies. The contribution from enterprises to the household economy was found to be greatest from companies, followed by cooperatives and then networks. The effective practices of the CBFEs in increasing income benefits were found to include representation of the poor and marginalized groups in executive committees in the FUGs-based enterprises, targeted employment of the poorest in the collection of non-timber forest products and in processing units in networks, and enabling the poor to own share capital in cooperatives and companies. The common constraint across all these categories was found to be lack B. H. Pandit ICIMOD, GPO box: 3226, Kathmandu, Nepal of adequate capital to sustain the enterprises without external support.The specific constraints were small membership and land size among FUGs, lack of legal recognition of networks, lack of management skills and member discipline for cooperatives, and lack of raw materials and marketing capacity for companies. The paper also discusses: the importance of further policy support to formalize forest user groups into networks, cooperatives and private companies; value addition to forest products; and capacity building for CBFEs, government line agencies and business services providers.

The Philippines is one of the many countries that currently acknowledge the presence of indigenous peoples (IPs) within their territories. This acknowledgment often comes with a formal recognition of the rights of IPs, including the right to practice their customary laws. Because of the equal existence of overarching state laws, this formally leads to a situation of legal pluralism for IPs. For many forest conservation advocates, legal pluralism for IPs, particularly with regard to land ownership and forest management, is expected to help conserve forests. This expectation, however, is founded on the erroneous assumption that the traditional land use of IPs is nondestructive and that traditional land ownership is communal. Using a relatively long historical perspective, this article demonstrates that these assumptions do not apply to the Kalanguya of Tinoc, the Philippines. In contrast to the notion of IPs being market-averse, this article further demonstrates that many Kalanguya have been and remain "capitalists". The article favors the inclusion of a market-based forest conservation policy, which is arguably consistent with the reality of value pluralism.
