Smallholders represent a significant portion (38%) of oil palm cultivation in Indonesia, and represent a critical component of the palm oil industry, as well as constitute a significant opportunity to improve livelihoods in resource-poor settings. Smallholders’ engagement in oil palm cultivation began as part of Indonesian government to promote tree plantation crops in the late 1970s. The initial programme consisted basically of direct state investments through state-owned companies (PTPN) and was integrated with government-sponsored transmigration programmes to provide a labor force for the new plantations. This integration was embryonic for smallholder engagement in state-led agribusiness. The emergence of smallholder oil palm planters constituted a spread effect of plantation development led by the government. The state agribusiness-driven policy has transformed rural areas and settlement development was started in the surrounding of large-scale oil palm plantation.

Root cause of good and bad - AgriYouthNepal Friday Sharing with Dipendra Shahiagriyouthnepal
The world is so much divided on the GMO debate. The world population is expected to reach 9 billion by 2050, and billions of people go to bed hungry each day. To tackle the problem of poverty, hunger and malnutrition, scientists have developed plant varieties that could fight disease, enhance flavor, resist pests, improve nutrition and survive drought by modifying the DNA of one organism through the introduction of genes from another. Around the world, communities are fighting against the cultivation of genetically engineered crops while there are scientists who advocate for GMOs. Are they safe? How do they impact the environment? Can they improve food security? Is the world better off with or without GM food?

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

9. Why? one of the main reasons is…
Lower concern and effort in genetic exploration
and pre-breeding by both public research and
domestic seed companies, due to
• Low interest and role conflicts of public
breeding
• low interest and capacity of private seed
companies

10. Missing linkage: Genetics exploration and Pre-breeding
中国玉米育种的技术缺环
• Quick jump and limited foundation in
breeding research (从原始OPV跨入双交种阶

13. Why? another reason….
No right Vs for right location and right farmers…
Limited understanding of the differentiation and changes of
the context, farmers’ farming system and their livelihood
Socio-economic change and climate change
- urbanization/migration, market and income driven, low interest in
agriculture, extreme weather, more drought,
Income structure change: less % of farming come
labor change: farming labors are women and the old now
farming system change:-more easy cash crop, less food
crop, less labor input

16. Participatory Plant Breeding (PPB) Definition
PPB:
close collaboration between researchers and
farmers and other stakeholders, covers the
whole cycle of activities associated with plant
genetic improvement. (Identify objectives,
materials, fields, selection, evaluation, and
improvement, small scale seed production,
distribution etc)
PVS: Participatory Varietal election (PVS)….is
just involve farmers in part/s of the cycle…
17. Why participatory plant
breeding?
为什麽参与式育种
• Marginal, stress prone regions farmers’
needs
• Biodiversity + productivity increase are
twin goals for sustanable yield increase
• Diversity maintenance + exploration is a
base for both farmer and formal systems
18. Major PPB steps/activities in two systems
• Aim: Linking formal and farmers’ systems and enhancing
their complementary supporting roles
Formal breeders: 1) M collection, documentation, farmers’ needs
2) field experiment, lab analysis,
3) Strategic crossing
4, Ex-situ conservation
Farmers: a) participate in evaluation, selection and experiment
b) improvement of OPV supported by breeders
c) direct adoption of appropriate impr OPVs & hybrids
d) in-situ conservation
e) small scale seed production and value adding

• (1)170 landraces collected in field, documented in 3
provinces (Gunagxi, Yunan, Guizhou) in 2009-2010
• (2) Lab analysis of landraces’ biodiversity, grouping of the
170 landraces in ICS, CAAS, 2010
• (3) experiment for comparison of 34 landraces collected 20-
30 years ago with same lines in cultivation now (2009-2010)

21. In Genetic resource exploration (2)
4)170+31 landraces for joint experiments
(evaluation and screening) 3 sites, two repeats
in 3 provinces in 2011,
(5) Strategic grouping and crossing of their own
landraces by the 5 breeding groups from the 3
provinces in different sites for specifically local
adaption
(6) Lab analysis of landraces’ biodiversity, grouping
etc (201 landraces in 2011)
23. Initial results of Lab result: of 170 landraces,
Field and Lab analysis analysis enhancing recognition of
landraces, TK and farmers’ roles
2009-2010
The same germplasm (20-30 years ago and now) are different, in field ones are more
diversity rich and adaptive to changes ….. Adaptation, evolution… process
170 landraces had been assigned into 2 groups clearly with remarkable diversity,
two maize agro-ecosystems
The genetic structure of the landraces was well compatible with geographical pattern.
Gene flow occurred in the SW
Characteristic diversification due to the bio-ecological environments, farmers’
selection based on their rich culture, TK and diversified livelihood needs
24. PPB in farmers’ field

areas, need integrated approach and collaboration …..
35. Some recommendations
Linking science research with farmers’ needs
1. More efforts in GR exploration and pre-breeding with
more involvement of farmers, to ensure genetic gains
keep pace with climate change and demand
2. Experimenting with farmers, understand farmers’ needs
and interests, match breeding priority with farmers’ needs
3. Decentralized and regional specific technology
development and extension strategies
4. Extension and farmer training: public extension (farmer
field school, in field advices etc), farmer cooperatives,
enterprise contracting farming,
5. linking different disciplines, stakeholders (inc farmers),
sectors, levels via Integrated and collaborative approach
